Our Payment Gateway Development Process
Weeks 1-2 on a typical build: we map your transaction flows, target markets, payment methods and PCI DSS scope, then define a focused MVP so you can launch quickly.

Weeks 3-10: we build transaction processing, tokenization, fraud scoring and reconciliation in agile sprints, integrating with processors, banking APIs and your existing systems.
Weeks 10-14: QA, load and security testing and PCI DSS evidence preparation, then deployment, merchant onboarding and transaction migration. Timeframes are Groovy estimates and vary with scope.
Our team creates intuitive merchant and customer interfaces while selecting secure, scalable technologies—using microservices, high-performance databases, and modular architecture for future growth.
As a leading payment gateway software development company, we build secure, compliant, and scalable solutions aligned with global and regional financial standards. Our platforms enable seamless transactions, advanced fraud protection, and a smooth payment experience for businesses and their customers.
We set up the quarterly Approved Scanning Vendor (ASV) scans and annual penetration test cadence your acquiring bank requires to keep PCI-DSS attestation current.
Payment processing services run in a segmented environment isolated from the rest of your application infrastructure, reducing audit scope for the annual PCI assessment.
We architect to keep raw card data out of your systems entirely (tokenization + hosted fields), which minimizes your PCI-DSS SAQ scope to SAQ A or A-EP instead of the full SAQ D.
The PCI Security Standards Council lists v4.0.1 as the current PCI DSS version. Your validation level depends on your card-brand transaction volume (Visa’s explanation), so we confirm your level with your acquirer in discovery and design to it (PCI SSC).
For card payments with customers in the European Economic Area, PSD2 requires Strong Customer Authentication, typically via 3-D Secure. We build the authentication flow, exemption handling and off-session payment mandates (Stripe’s SCA guide).
We integrate identity verification, sanctions screening and transaction monitoring into merchant and customer onboarding, configured to the requirements of your sponsor bank, acquirer and operating regions.
Card numbers are replaced with tokens before they reach your core systems, and every payment page and API call runs over TLS 1.2 or higher. Webhooks are signature-verified, so only your processor can trigger payment events (see Stripe’s integration security guide).
We help fintech businesses build secure, scalable payment gateway software that supports revenue growth and customer loyalty. As a payment gateway software development company, we deliver end-to-end development from architecture to deployment, shaped around your transaction workflows, PCI DSS scope and growth plans. Whether you are building a custom gateway, adding payment methods or layering in fraud prevention, we combine engineering depth with fintech context so your platform stays reliable and regulation-ready.
We understand how a payment moves from checkout to authorization, capture, settlement and reconciliation. Our team builds gateway software that simplifies those flows for merchants while respecting card-network and acquirer rules.
We design to keep raw card data out of your systems, build encryption, tokenization and access controls in from the start, and prepare the evidence your assessor or acquirer asks for. See our fintech software development approach.
Groovy estimates (AI-First delivery): Stripe or Braintree integration with a fraud layer, about $18,000-$38,000 in 4-6 weeks; MVP custom gateway, $40,000-$80,000 in 8-12 weeks; enterprise multi-market gateway, $150,000-$260,000 in 20-28 weeks. Final quotes depend on scope; see our payment gateway development cost guide.
We design idempotent APIs, queue-based processing and ledger reconciliation so the platform grows from your first merchants to high transaction volumes. We also tell you honestly when integrating an existing processor is cheaper than a custom build.
Our engineers work across payments, lending and banking products. Explore our fintech software development company page or our digital banking and payment solutions.
Dashboards track authorization rates, declines, chargebacks and fraud indicators in real time, so your team can act on issues quickly instead of waiting for settlement reports.
We provide continuous optimization, processor and API updates, and support as card-network, PCI DSS and regional requirements evolve, so your gateway stays current after launch.

Alex
CEO, Chainex tech corporation
A payment gateway software development company designs, builds and integrates the software that securely transmits payment data from your checkout to processors, card networks and banks. At Groovy Web that includes custom gateway platforms, merchant onboarding, tokenization, fraud scoring, reconciliation and reporting, built around your transaction workflows.
These are Groovy estimates for AI-First delivery, not fixed quotes: about $18,000-$38,000 to integrate Stripe or Braintree with a fraud layer, $40,000-$80,000 for an MVP custom gateway and $150,000-$260,000 for an enterprise multi-market gateway. Scope, markets and PCI DSS level drive the final number. See the full payment gateway development cost breakdown or request a quote.
Typical Groovy estimates: 4-6 weeks for a processor integration, 8-12 weeks for an MVP custom gateway and 20-28 weeks for an enterprise gateway. A custom build usually runs requirements and architecture in weeks 1-2, core development in weeks 3-10 and testing and certification preparation in weeks 10-14. Timelines vary with scope and acquirer approvals.
We integrate cards, digital wallets such as Apple Pay and Google Pay, bank debits and buy-now-pay-later options, plus multi-currency support. With Stripe, for example, you can dynamically display 40+ payment methods. We also connect gateways to e-commerce platforms, CRMs, ERPs, banking APIs and fraud tools.
We design to minimize your PCI DSS scope (tokenization, hosted fields, network segmentation) and prepare ASV scans and assessment evidence. The PCI Security Standards Council lists v4.0.1 as the current version, and your validation level depends on card-brand transaction volume. For EEA customers we implement PSD2 Strong Customer Authentication with 3-D Secure (Stripe’s SCA guide). We are not a QSA, so your assessor signs off on attestation.
If your volume is modest, integrating a provider such as Stripe is usually faster and cheaper, and it can shrink your PCI DSS scope. A custom gateway makes sense when you need control over routing, pricing, merchant onboarding or multi-market operations, or you are building a payments product for others. We assess both options in discovery and recommend the cheaper route that meets your needs. Related reading: AI in payment gateways.
