Frequently Asked Questions

Below you will find answers to the most common questions.
What’s the difference between a payment getaway and a payment processor?

A payment gateway is a tool that safely transmits online transaction data to the processor to continue the transaction life cycle. A payment processor takes part in the transaction, transferring data between you, the client, the issuing bank (the bank that issued your client’s card), and the acquiring bank (the bank in which your company account is registered). Simply put, the difference is that the payment gateway is an instrument that reports on the execution or rejection of transactions, and the processor facilitates the transaction itself.

How to choose the right payment gateway?

When choosing the most suitable payment gateway, consider such nuances as what currency the system accepts, in which countries it is available, and what commission per transaction it charges. The most reliable and popular solution is PayPal, which services more than 200 countries.

How much do you charge per configuration?

We evaluate the specification requirements that need to be developed. This can be either the implementation of changes in an existing business or programming a project from scratch. In any case, the price depends on the complexity and duration of development. We offer our customers the best prices.

How much time does project development take?

The time frame depends on the complexity of the project. The more development is needed, the more time it will take and the higher the price will be. Basic integration with payment systems takes up to one week, depending on the getaway. Designing of purchase forms and pages will take extra time. Also, note that you will have to wait for a response from the payment gateway provider after signing the agreement.

How do you store credit card information?

Saving credit card data in the database occurs only at the request of the user. All the solutions that we provide for the storage of user data comply with the best encrypting and security practices as well as local laws.
