About the Buy Now Pay Later schema

We have provided a system that enables deferred payments.
BNP (Buy Now Pay Later) L is a modern form of payment that allows consumers to manage their spending while merchants and banks increase sales and revenue. The right implementation of BNPL in a fintech or bank can be a competitive advantage and attract new customers.

Payka - screen from the application

Payka allows users to pay utility bills such as energy, TV, Internet, or telephone (in the Buy Now Pay Later schema). The online payment process is fully automated, quick and simple: after selecting Payka method on the payment gateway, you enter your identification details, if you are recognized, you accept terms with an SMS code. Otherwise or if you use Payka for the first time, you are logging into your bank account to identify yourself through PSD2/AIS.

Payka’s payment process is fully secure. All transactions are encrypted and executed through secure servers and communication channels. The system is integrated with Blue Media’s payment gateway, so there is no need to integrate it with each utility provider separately.

Benefits of implementing BNPL

For the end user (consumer):

  • More financial freedom – spread the cost over instalments instead of paying everything upfront.
  • Interest-free payments – many BNPL options have 0% interest, making them cheaper than credit cards.
  • Easier access to products/services – customers can afford more significant purchases without immediate expenses.
  • No complex paperwork – a quick identity and credit check is often all that’s needed, with no lengthy applications.
  • Better cash flow management – funds stay available for other expenses instead of being locked into a single purchase.
  • Added security – users can check the product before paying using a ‘pay later’ model.

For the bank or fintech:

  • More customers and loyalty – flexible payment options attract new users and keep them engaged.
  • Valuable consumer insights – transaction data helps understand customer habits and tailor offers.
  • Higher transaction volume – BNPL encourages frequent purchases, boosting overall financial activity.
  • Competitive advantage – an alternative to credit cards and loans that keeps banks relevant in modern finance.
  • Increased e-commerce partnerships – BNPL raises the average transaction value, making it appealing for merchants.
  • Upselling opportunities – BNPL users may also be interested in premium accounts, insurance, or other banking products.

How does BNPL work?

Purchase a product or service

The customer selects the BNPL option when finalising an online or stationary shop order.
The retailer immediately receives the full amount from the BNPL provider (e.g. a fintech or bank).

Credit decision

Most BNPL services offer quick online verification, assessing creditworthiness through purchase history or credit scoring. Some skip full checks, increasing accessibility but also risk. Payments can be deferred or split into instalments.

Deferred payment or repayment in instalments

Pay later model – The customer has, for example, 14 or 30 days to make the payment at no extra cost.
Instalment model – payment is spread over several instalments (e.g. 3, 6, 12), often interest-free if paid on time.

Repayment of the obligation

The customer repays the instalments according to the schedule by transfer or automatic debit from the account/card.
In case of delays, additional fees or interest may be charged.
