Understanding Embedded Finance: Benefits and Examples

How do you choose the right technology stack for payments?

At PixelPlex, we select technologies based on your specific requirements for transaction volume, latency, global reach, and compliance needs. We evaluate factors like real-time processing demands, scalability for peak sales, and ecosystem integration to match the optimal tech to your goals.

How long does it normally take to build a custom payment solution?

Typically, payment solution software development needs an MVP. This step might take from 4 to 7 months. The timeline is dictated by complexity. A basic gateway integration moves faster, while a full-scale payment facilitator (PayFac) platform with multi-party settlements and advanced risk management requires a longer, phased approach.

How does the interaction with the internal team happen?

We operate as a collaborative extension of your team. You'll review designs, participate in security workshops, and provide feedback on payment flows at critical stages. We manage the technical execution, but your domain expertise is vital to ensure the solution aligns perfectly with your business operations.

What specific payment features can you implement?

We commonly implement: white-labeled checkout experiences, subscription/billing engines, fraud detection suites, merchant onboarding systems, split payment/payout orchestrators, detailed analytics dashboards, and integrations with major processors (like Stripe, Adyen), banks, and accounting software (like NetSuite, Xero).

How is our financial data and intellectual property protected?

You retain full ownership of all source code, unique algorithms, and IP developed for your project. We enforce strict NDAs, adhere to industry security protocols (ISO 27001), and sign work-for-hire agreements that guarantee all rights are transferred to you upon project completion and payment.
