Why outstaff instead of hiring in-house?
With Smartbrain.io you tap into a live bench of pre-vetted JavaScript professionals who have already solved expense tracking payment gateway headaches for banks, SaaS vendors and retail chains. Outstaffing slashes recruitment lead-time from months to days, eliminates payroll taxes and HR overhead, and lets you expand or shrink talent on demand. You keep full product ownership while we manage sourcing, vetting, compliance and continuous up-skilling. The result: lower total cost of ownership, faster feature delivery, and the freedom to focus on revenue rather than head-count.

What CTOs Say About Our Expense Tracking Payment Gateway Experts
Our two-week deadline looked impossible until Smartbrain.io deployed a senior Node.js & React pair already versed in micro-ledger architecture. They refactored our JavaScript microservices, plugged the new expense tracking payment gateway API, and lifted test coverage from 62 % to 91 %. Productivity jumped and my core team stayed focused on roadmap items.

Expense Tracking Payment Gateway Case Studies
Retail Chain Gains Real-Time Spend Visibility
Client: National big-box retailer with 420 stores.
Challenge: Legacy POS could not surface real-time data from the new expense tracking payment gateway, delaying reconciliation by two days.
Solution: A Smartbrain-supplied pair of JavaScript engineers wrapped the gateway with a TypeScript microservice and added WebSocket push to a React admin panel. Integration completed in 16 days, fully remotely.
Result: 38 % latency reduction in transaction reporting, $140 K annual labor savings, and same-day close of books.
FinTech SaaS Cuts Reconciliation Time
Client: Y-Combinator–backed SaaS for startups.
Challenge: Scaling transaction volume caused the existing expense tracking payment gateway function to exceed 10-second SLA.
Solution: Three senior Node.js developers from Smartbrain re-architected the Lambda pipeline with streaming parsers and DynamoDB batching while a React expert optimized the reporting UI.
Result: Reconciliation speed improved by 67 %; system now processes 1.2 M records nightly with zero throttling.
Global Logistics Slashes Payment Failures
Client: Fortune-500 logistics provider.
Challenge: Cross-border fees caused 4 % of shipments to error out in the expense tracking payment gateway module.
Solution: Smartbrain’s augmented Vue.js & Go team added currency-specific retry logic and GraphQL mutations, deploying via GitOps across 11 regions.
Result: Payment failure rate dropped to 0.3 %, saving $2.3 M yearly chargebacks and restoring customer trust.
