Payments and billing
Acquiring, subscriptions, refunds, reconciliation
- Payme / Click and others
- Visa/Mastercard via provider
- Escrow and payment holds
- Payment webhooks, retries, dedup (idempotency)
- Receipts and fiscalization (if required)
We connect payments, authentication, maps/geo, chats/bots, CRM/ERP, media storage, push notifications, and product analytics. For every provider we implement webhooks with idempotency and retry logic, deliver GA4/Firebase event maps, and define SLA operating runbooks.
Choose the setup by your use case: start with one provider and expand step by step.

Reliability and scalability
Critical inbound events pass through idempotency control and queue processing, with retry policy based on exponential backoff. All events are logged and traceable in admin tools. Failures are classified (client / provider / network), metrics and alerts are visible in dashboards. For mission-critical flows, we enable two-step confirmation.
We connect widely used services to accelerate launch and reduce operational risk (subset of available integrations).
We review business model and define technical scope, success KPI, and scope boundaries so budget stays controlled.
We build an interactive prototype so you validate logic and flows before expensive implementation starts.
We create modern interface and UI kit. New features remain visually consistent and easy to scale.
Sprint-based execution with weekly demos. You see real progress continuously.
QA validates the product across devices. We handle App Store / Google Play release and analytics setup.
After launch we continue with SLA support and product growth based on real usage data.
Each webhook uses an idempotency key and delivery journal. We use queues and backoff retries, deduplicate duplicates, and track status in 24/7 monitoring.
Typically 3-7 business days per provider, including capture/refunds, statuses, webhook handling, test cases, and technical documentation.
Yes. We use provider adapters so you can switch providers and balance fees/risk without redesigning your application.
Yes. We deliver GA4/Firebase event schema (screens, parameters, user properties), reporting examples, and BigQuery export setup.
