FAQ about credit cards billing

Debit payments are made with a debit card or with the debit feature of a combination card and debited from a bank account. Credit payments are made with a credit card or with the credit feature of a combination card.

You’ll receive a bill for your credit payments once a month and a 35-day interest-free billing period on average. When you receive the bill, you can decide whether you want to pay the agreed minimum payment, the entire outstanding balance or anything in between.

You can receive OP’s credit card bills as e-invoices, as direct payment or as a paper bill. To receive e-invoices, you need a Finnish bank’s online bank user identifiers. If you don’t have online bank user identifiers, you can use direct payment or a paper bill. E-invoice and direct payment are free-of-charge billing methods. For a paper bill we will charge 3 euros/bill.

If you have OP's credentials, you can check your credit card billing method as follows:

• OP-mobile: Accounts and cards - Select a card - Bill - Billing method
• Op.fi service (in Finnish): Rahat (tai Kortit) Money (or Cards) – Omat kortit My cards - Select a card – Laskutus Billing - Laskutustapa Billing method

If you do not have OP's credentials, you can use the chat feature (in Finnish) or call our Customer Service to check which billing method you are using. The K-Plussa Maksuaika card details are shown on the op.fi service that you can access with the user ID of any Finnish bank.

You can see the e-invoices and the related payment proposals on OP-mobile and the op.fi service at least two weeks before the due date. If the e-invoice shows no amount to pay out, it will go directly to the received e-invoices.

My archive is the easiest way to view the credit card bills you have received.You can find copies of bills in My archive for the past two years irrespective of the billing method.

Go to My archive as follows:

• OP-mobile: More - My profile - My archive or Select card – Billing – View bills
• op.fi service (in Finnish): your name – Oma arkisto My archive

You can view OP's e-invoices for more than the last two years on OP-mobile and the op.fi service.

Depending on the billing method, you can pay the bill in many ways; e-invoice, direct payment or using the barcode or account number in the paper bill.

When you order an e-invoice, you can choose that the e-invoice is automatically confirmed and paid on the due date. In such a case, the minimum monthly payment is automatically debited from the account of your choice. You can edit the payment until the due date. You can also set a maximum amount per bill so that any payments below that amount will be confirmed automatically. You will separately confirm any bills above that amount on OP-mobile or the op.fi service. The payment account and the settings for automatic payment always apply to all credit card bills from OP.

You can also repay your credit or pay your entire bill by using the Repay credit button on OP-mobile or the op.fi service. The credit repayment will be immediately displayed in the credit transactions and will be available right away. On OP-mobile, you can repay your credit easily and in real time by transferring money from your account to the credit card with the My transfer button on the homepage.

If you have used incorrect payment details and the payment is not shown in the credit or as a refund in your account, contact our Customer Service.

The payee and payee's account number are always the same for all OP credit cards. The reference is card-specific, in other words, it remains the same every month.

If your card is changed, for example, if it is replaced because you have lost your previous card, its validity has expired or the card is broken, the payment details will remain unchanged. If you apply for a new card, in other words, you make a new card agreement, the reference number will change.

You can repay the debt with an amount of your choice or pay off the balance in full. Repaying your credit is easy in OP-mobile or on the op.fi service. Select your card and then select Repay credit.

Extra repayments are free of charge, and you can make credit card repayments as frequently as you like. Repayments made with the Repay credit button will immediately be displayed in the credit transactions and will be available right away.

When you pay your credit card bill, it is entered as payment with a delay of 1–2 days, depending on the time of the day when you make the payment. The delay is due to the fact that the payment is entered in the pool account from where it is allocated to the correct credit card once a day, based on the reference number. 

You can also make a credit repayment or pay your entire bill with the Repay credit button in OP-mobile or on op.fi. The credit repayment will immediately be displayed in the credit transactions and will be available right away. In OP-mobile, you can repay your credit easily and in real time, by transferring money from your account to your credit card with the My transfer button on the homepage.

You can change the minimum payment or due date for upcoming bills, but the bill already created must be paid as such.

The minimum monthly payment is 3% and no more than 100% of the credit card balance. Due date options are 7th, 15th, 23rd and the last day of the month. If the credit card account has balance after the due date, we will charge interest and an account service charge for the balance in the next bill.

If the payment is delayed for two (2) weeks, you will get a reminder by post for which we will charge you 5 euros according to our Charges and Fees. We recommend paying the unpaid amount at the latest when the reminder has arrived. If the payment is delayed, getting a new credit from OP or increasing the credit limit may become more difficult.

If you have any questions, please contact our Customer Service at 0100 0500 (Mon–Fri 8–19). If you are unable to follow the payment scheme on which we have agreed, please call Credit Control at 010 252 7750 (Mon–Fri 9–15).

You can see your bills in My archive and on OP-mobile under the card details by selecting the Billing tab and then View bills. Check from your account transactions whether your previous bill has been paid and whether it has been paid using a correct account and reference number. Please contact our Customer Service if necessary.

Extra payment reduces your credit card balance, or then we take account of the payment in upcoming bills. You can also use the extra payment free of charge by making payments with your card. If you want to transfer credit to your account, we will charge for the transfer a fee according to our Charges and Fees.

On your bill, you will see your total credit card balance on the billing date. If there have been transactions on your credit card account after the billing date, you can check your balance on the date of payment on OP-mobile, the op.fi service or by contacting our Customer Service. You can make payments conveniently on OP-mobile or the op.fi service by using the Repay credit button. If you select Pay full amount, you will automatically pay the total balance on your credit card account on the payment date. We will charge any interest afterwards in your next bill.

To pay off the entire credit used in your old credit card, read the answer to the question "How do I pay off the amount of the entire credit used in the credit card?" If necessary, you can transfer credit facility from your new credit card to your account by using the Transfer to account feature. We will charge for the transfer a fee according to our Charges and Fees. You can ask our Customer Service to refund the fee to you as soon as your old card's balance is shown as paid.

The invoice contains all transactions and payments made on the credit card account during the billing period. It is possible that any purchases you made just before the turn of the billing period will not show until the next bill. This is because the purchases are not recorded in the credit card account immediately but with a delay of a few days, depending on the payment data transfer schedules of the merchant. At the time of purchase, the bank makes a preauthorisation for the purchase in the credit card account, in other words, gives the merchant a permission to sell, but the preauthorisation is not yet shown in the bill as transaction.

Transactions are shown in the bill based on their original dates of purchase or transaction. The bill shows the official name of the payee, which may be completely different from the name by which the company is commonly known or from the name shown in the receipt.

The minimum payment shown in the bill and in the payment proposal of an e-invoice or direct payment includes the agreed monthly instalment and any overdue monthly instalments and excess of the credit limit.

If there is a supplementary card attached to your account, or if you have received a new card with a new number, the bill will show all card transactions itemised by card number.

If you need not pay anything, the billed amount is 0 euros. If the bill shows a payable amount and the selected billing method is paper bill, a paper bill surcharge based on the list of charges and fees will be added to the bill. E-invoice and direct payment are free of charge.

Does the content of the credit card bill make you wonder? We have written an article to help you, in which we explain in detail the items and amounts found on the front and back of the credit card bill.  

Read here how you read your credit card bill

You will get a bill whenever there are transactions or payments in the credit card account. If you need not pay anything, the billed amount is 0 euros. Thus the bill may be just a bank statement of the payment you have made in the credit card account.

The Consumer Protection Act requires that a bank statement is created whenever there are transactions in the credit card account. The bank statement ensures that you will surely get information on the transactions.

The bill shows the official name of the payee, which may be completely different from the name by which the company is commonly known or from the name shown in the receipt. The company’s domicile may also be different from the one shown in the receipt. You can, for example, make Google searches on the Internet by using the company’s official name to find the name of the payee.

The bill also shows the date on which the purchase was made. However, the bill does not state directly whether the purchase was made online or in store. Think whether you may have bought something somewhere on the day in question.

If you don’t recognise the transactions shown in the bill, please contact our Customer Service immediately. Outside the opening hours of the Customer Service, call OP Deactivation Service at 0100 0555 (local/mobile network rate, available 24/7) and deactivate your card immediately. After your card has been deactivated, you will get a new card and PIN within 1–2 weeks in the delivery method you selected. You can make mobile payments with Apple Pay or Google Pay during that period, too. When the card is deactivated, you can add a new card to the Apple Wallet and Google Wallet apps. Garmin Pay and Samsung Pay can be used if the card has been previously added to the service. Once you have received the new card, you can add it to the service.

One bill always includes the transactions of approximately four weeks. The billing period begins on the day after the billing date and ends on the next billing date.

The bill contains all transactions and payments recorded in the credit card account during the billing period. It is possible that purchases you made just before the turn of the billing period will not be recorded until the next bill. You can normally see transactions in the credit card account a few days after the actual transaction and the related preauthorisation.

The table below shows the due date options for a credit card bill, the billing date and the billing period, in other words, the period of transactions shown in the bill.

If you want the transactions of one calendar month in a single bill, you should select the 23rd day of the month as the due date. In that case, the bill will be generated on the 1st day of the same month and it will show the transactions from the 2nd day of the previous month until the 1st day of the current month.

In the op.fi service, you can conveniently view your transactions for each billing period. Go to My cards, select your card and then select the Transactions tab.

Pay the amount in the bill that you see under "minimum payment". If you are unable to pay the bill, contact our Customer Service. We will take account of any refunds of transactions in upcoming bills. 

A monthly account service charge will apply if you have interest-bearing debt in your credit card account. The first credit card bill will never include either interest or account service charge. If the credit card’s total outstanding balance is not paid by the bill’s due date, then interest and an account service charge will be calculated on the balance after the due date and charged in the next bill.

An e-invoice is a bill sent to the op.fi service and OP-mobile in electronic format. Paying e-invoices is easy with a PC, tablet or smartphone. E-invoices are easy to use, flexible and secure, and have just one third of a paper bill’s carbon footprint.

The bill will arrive at least two weeks before its due date. You can choose when to pay the bill, from which account to pay it, and how much you will pay.

• If you have OP's credentials, you can order your credit card bills as e-invoices on OP-mobile or the op.fi service.
• If you don’t have OP's credentials, see your own bank’s instructions on how to start using e-invoices.

1. Go to the Billing tab under card details. 
2. Select Order e-invoice under Billing method. For the order, you don’t need any details because the payee’s details and the credit card bill reference number is automatically brought to the e-invoice order.
3. Select the payment account if you like.
4. If you like, you can also have your bills automatically confirmed and paid on the due date. If you select automatic payment, remember to always check the transactions listed in the bill before the bill’s due date. The payment settings you selected apply to all e-invoices of OP’s credit cards.
5. You have now ordered an e-invoice. You’ll get a notification of an incoming e-invoice by enabling notifications in the app’s settings.

1. First check the reference for your credit card. Select Omat kortit (My cards) under Kortit (Cards) and the card whose credit card bill reference you want to see. Then select the Laskutus (Billing) tab and you’ll see the bill’s reference number. You can also see the reference number in the paper bill.
2. Next select Vaihda e-laskuun (Switch to e-invoice) under Laskutusasetukset (Billing settings).
3. In the search field, type OP Vähittäisasiakkaat Oyj (OP Retail Customers plc). Select the payee OP Retail Customers plc with “Visa/Mastercard bill” as the subject of invoice and tap Jatka (Continue).
4. Enter your credit’s reference number.
5. Select payment account.
6. If you like, you can also have your bills automatically confirmed and paid on the due date. If you select automatic payment, remember to always check the transactions listed in the bill before the bill’s due date. The payment settings you selected apply to all e-invoices of OP’s credit cards.
7. Select Tilaa e-lasku (Order e-invoice). When ordering an e-invoice, you can also order a notification of a received e-invoice.

Check the billing date and the minimum payment amount in the bill. If you have paid at least the minimum payment amount after the billing date, you can ignore the bill.

If you have already paid the e-invoice you just received, you can delete it. You can delete an incoming e-invoice if you have already paid it. You can still find the e-invoice in the received e-invoices and in My archive. You will continue to have e-invoice as your billing method, and you will receive your next bill as an e-invoice.

In the op.fi service (in Finnish), you can delete an incoming e-invoice by selecting Muokkaa (Edit; a pen icon next to the invoice) – Poista maksu (Delete payment).

On OP-mobile, select the payment under either Confirmed or Unconfirmed payments - Delete payment.

Change the due date to a date of your choice, for example Today, and confirm the payment.

If you do not have access to OP-mobile or the op.fi service, direct payment is the easiest and safest way to pay bills. With direct payment, your bank will pay your bills for you on the due date. You will receive by letter a direct payment notification in which you can see the amount to be debited and the transactions on the card.

If you want to start using the direct payment option, call your own bank’s Customer Service to agree on this. Keep the latest bill close at hand to check the details needed for the payment.

If you have selected either automatic payment for your e-invoice or direct payment, the bank will try to debit the payment on the due date and on the following two banking days, in the morning and in the evening. If your account has insufficient funds for the payment, the payment will bounce, in other words, remain unpaid. The bounced payment will be shown for two weeks after the due date. You can’t edit the details of a bounced payment. Instead, you must make a new payment by using the same payment details.

If you made an e-invoice order after the billing date, you will not receive an e-invoice until the next billing period. The billing date is three weeks before the bill due date.

If you get even your next bill as a paper bill, check that your e-invoice orders include an order to the payee OP Retail Customers plc, that the subject of invoice is Visa/Mastercard invoice and that the reference is the reference shown in the billing details of your card.

OP-mobile: Reference: Accounts and cards - Select a card - Bill - Repay credit - Reference
Op.fi service (in Finnish): Reference: Rahat (tai Kortit) Money (or Cards) – Omat kortit My cards - Select a card – Laskutus Billing – Laskun viitenumero Reference number of bill

You can also delete the e-invoice order, make it again next day and check if your billing method changed into e-invoice. If necessary, contact us by chat (in Finnish), call us or send a message on OP-mobile or the op.fi service.

OP's credit card paper bill costs 3 euros per bill sent for outstanding credit card balances.

The paper bill surcharge is a fee for the additional service of sending your credit card bill on paper. The options for receiving your bill free of charge include e-invoice and direct payment. The paper bill surcharge will apply if you receive a bill for outstanding credit card amount to be paid is larger than 5 euros. If you receive a so-called bank statement which only lists the transactions for the billing period but there is nothing payable, the paper bill surcharge will not apply. The paper bill surcharge will apply from the very first paper bill.

Start using e-invoices or direct payment. These are free-of-charge billing methods.

• Switch to e-invoices if you have OP's or another bank's credentials.
• If you do not have the option of using OP-mobile or the op.fi service, you can start using direct payment.

How to start using e-invoices – See instructions for: How do I order an e-invoice?
How to start using direct payment – See instructions for: What is direct payment and how can I start using it?

We recommend that you order your bill as e-invoice to ensure that your bills are always safe.

Regardless of the billing method, you can find a copy of your bill in My archive.

Go to My archive as follows:

OP-mobile: More - My profile - My archive, or
op.fi service (in Finnish): your name – Oma arkisto My archive

The table below shows the due date options for a credit card bill, the billing date and the billing period, in other words, the period of transactions shown in the bill.

If you want the transactions of one calendar month in a single bill, you should select the 23rd day of the month as the due date. In that case, the bill will be generated on the 1st day of the same month and it will show the transactions from the 2nd day of the previous month until the 1st day of the current month.

If the due date is the last day of the month and it is on a weekend or a public holiday, the due date will be moved to the next month and, therefore, you may have two credit card bills due within the same calendar month. If you are using automatic payment and have selected the last day of the month as the due date, it is recommended that you change the upper limit of the automatic payment from a monthly limit to a bill-specific limit.

You can change the due date in the op.fi service. You can change the due date of your credit card bill once every six months.

• op.fi (in Finnish): Omat kortit My cards - Select card – Kortin ja luoton tiedot Card and credit details – Laskutus Billing – Laskun eräpäivä Bill due date – Muokkaa Edit

You have four options for the due date of your credit card bill: the 7th, 15th, 24th or the last day of the month. If you change the due date, the change will take effect from the next bill to be generated. Please note that the current billing period can be longer or shorter than usual due to the changed due date. If the due date falls on a weekend or public holiday, it will be postponed until the next business day.

If you don’t have OP’s credentials, you can change the due date by chat (in Finnish) or by calling us. The K-Plussa Maksuaika card details are shown on the op.fi service that you can access with the user ID of any Finnish bank.

The minimum payment is calculated as a percentage of the used credit on the billing date. As the outstanding balance decreases, so will the minimum payment. However, the minimum payment will always be at least 30.00 euros or less if the used credit is lower than the said amount.

When you receive the bill, you can decide whether to pay the agreed minimum payment, the entire used credit or anything in between. If you pay less than the entire used credit, then interest and an account service charge will be calculated on the remaining part after the due date.

You can change the minimum payment in the op.fi service (in Finnish). You can change your credit card’s minimum monthly payment every six months.

• op.fi (in Finnish): Omat kortit My cards - Select card – Kortin ja luoton tiedot Card and credit details – Laskutus Billing – Luoton kuukausierä Minimum payment – Muokkaa Edit

As your credit card's minimum monthly payment, you can select 3 / 5 / 10 / 20 or 100% of the credit card balance on the billing date. The change will take effect from the next bill to be generated.

Minimum payment is the smallest amount that you must repay on the due date you've chosen. If you choose 100% of the outstanding balance as minimum payment, all payments you’ve made on credit will be debited on the due date. In such a case, you can’t repay a smaller amount but you have to pay the bill in full.

If you don’t have OP’s credentials, you can change the minimum payment by chat (in Finnish) or by calling us. You can manage the K-Plussa Maksuaika card in the op.fi service with the user ID of any Finnish bank.

Purchases paid with a credit card or the credit feature of a combination card will be interest-free until the first due date. In other words, if you pay the entire outstanding balance on the due date, you will not have to pay any interest or account service charge. The interest-free period is 35 days on average. If you make a purchase just before the billing date, the interest-free period will be from at least 21 days up to almost 50 days.

Purchases paid with a credit card will be interest-free until the due date of the next bill. If the credit card account has credit drawn down after the due date, interest and an account service charge calculated for the balance will be charged in the next bill.

If you pay with credit and interest is charged, the interest rate is the 3-month Euribor + 8.95%, plus a monthly account service charge of €3.50.

The interest is always charged afterwards. After the interest-bearing debt has been paid off, the interest up to the payment date will be charged in the next bill. If only interest is charged in the bill, there will be no account service charge. 

Example 1: If you pay a purchase of €599 using your card’s credit feature and repay it in instalments of €50/month, there will be a total of 14 instalments. For this period, you will pay a total cost of €82.73, which includes interest of €37.23 and account service charges of €45.50. (01/25)

Example 2: : If you pay a purchase worth €599 with your credit card feature and pay off the credit in six identical instalments, each instalment will be €105.50 per month. For this period, you will pay a total cost of €32.02, which includes interest of €14.52 and account service charges of €17.50. (01/25)

If you decide to pay only part of the bill, then interest and an account service charge on the remaining debt will be charged in the next bill.

Interest accruing between the billing date and the due date is not included in the credit card balance. Therefore, if you have paid down your credit in instalments and now pay off the credit card balance in full, the interest accrued up to the payment date will be charged in the next bill.

The effective interest rate is a tool for comparing the cost of credit when applying for credit. It does not reflect the actual costs that you will incur, including a possible monthly charge for the card, account service fee and credit interest rate, which are charged only if you have interest-bearing balance on your credit card. The effective interest rate calculation ignores the fact that a credit card is intended for continuous use and that you can pay down your outstanding balance whenever you wish.

You will be informed of the effective interest rate when you apply for credit. Besides interest, the effective interest rate includes all other costs of credit.

The effective interest rate is calculated based on the assumption that the entire credit is drawn down at the same time, the card’s monthly charge is 2.95 euros and the monthly account service charge 3.50 euros, free of charge e-invoicing is in use and the credit is repaid in 12 identical monthly instalments.

For example, the card’s monthly charge is lower for owner-customers than stated in the calculation for effective interest rate, because the monthly charge is included in the owner-customer’s daily service package. In addition, the monthly charge is paid primarily using OP bonuses.

Below you can find examples of the effective interest rate calculated for the OP Classic card:

The effective interest rate calculated for used credit of EUR 2,000 is 18,53 % (01/2025) if the customer has no daily service package or other discounts applied. The estimated total amount payable would be 2,181.66 euros.

You can find a valid list of service charges and fees at op.fi/hinnasto.

You cannot directly pay bills by using your credit card, but you can transfer credit to your bank account and then pay the bill from your account. Please note that services like Purchase Protection Insurance and Product Protection Insurance for owner-customers do not apply when you pay from an account. They require payment directly with the card.

How to transfer credit:

• OP-mobile – Select a card - Bill - Transfer credit to your account, or use the My transfer function
• op.fi (in Finnish) – Omat kortit My cards – Select a card – Siirrä luottoa tilille tai Siirto omalle tilille Transfer credit to your account, or use the Transfer to own account function

Transfers are subject to a charge in accordance with the list of charges and fees. You can find the valid list of charges and fees at op.fi/hinnasto.

OP bonuses can be used to pay service charges, such as the card's monthly charge or card renewal. We will charge the costs of credit, such as transfer from credit to the account or account service charge, from the credit account. You can't pay them with the OP bonuses.

OP Retail Customers plc issues and manages OP’s payment and credit cards.
