Fintech product and payment service development

In a payment product, users need to understand which transaction they are making and what happened to it after they confirmed it. Your team needs accurate statuses and reliable links between systems. We help design payment modules and customer accounts. We start with the product model, the roles involved and the requirements of the banks and payment providers that will process the transactions.

We map out the payment flow, access rights, activity history and interaction with external services. We build the interfaces and integrations and test how responses, errors and repeated notifications are handled. The terms of financial transactions and the required checks are defined together with your compliance and legal advisers. They become part of the product requirements and of the testing done before launch.

In our own products we have built Stripe payments and deployed document signing on the open-source DocuSeal engine. We can combine these areas with design, development and support. Browse our work at spng.space and describe your service model. Together we will identify the transactions to build into the first version.
