Localised for your market
Payment Gateway Integration in San Luis Potosí: local requirements we build for
Currency, tax, payments, data protection and 24/7 support — planned into the project from the first sprint.
Currency & pricing
Prices, invoices and reports in peso (MXN), with the transaction currency and FX rate stored on every record for cross-border sales.
Tax (VAT / GST)
Mexico applies VAT (IVA) 16%. We build tax-correct pricing, invoice fields and exportable tax reports; your accountant confirms treatment for your products.
Payments
Customers in San Luis Potosí expect SPEI / CoDi, OXXO Pay (cash), Cards with meses sin intereses and Mercado Pago — integrated with automatic reconciliation.
Data protection
Personal data is governed by the Federal Law on Protection of Personal Data Held by Private Parties (2025). We build consent, encryption, access logs and in-region hosting where required.
24/7 availability
San Luis Potosí is on UTC−6 (India (IST) is 11h 30m ahead). Our team works 24/7, so your full business day and any out-of-hours incident are covered.
Delivery timeline
Discovery starts within 5 business days of a signed proposal. Most payment gateway integration engagements ship a first production release in 6–14 weeks, with demos every two weeks.
The Challenge
Problems we see teams struggling with
High transaction failure and decline rates
Poor PSP routing and retry logic silently loses revenue on every failed or declined transaction.
Manual reconciliation overhead
Finance teams spend days manually matching PSP settlement reports against internal ledgers.
Limited payment method coverage
Missing local payment methods and currencies caps conversion in new markets.
No unified view across multiple PSPs
Operating multiple PSPs without a central orchestration layer makes routing, reporting, and risk management inconsistent.
FX cost leakage on cross-border transactions
Without FX-aware routing, businesses absorb worse conversion rates and hidden markup on every cross-border transaction than necessary.
Checkout abandonment from unsupported local methods
Requiring a card when local users expect a wallet, bank transfer, or QR payment method caps conversion before checkout even begins.
Our Approach
What our payment gateway integration work covers in San Luis Potosí
Payment orchestration & routing
Smart routing across multiple PSPs based on cost, success rate, and geography, with automated failover.
PSP & payment method integration
Cards, bank transfers, wallets, QR payments, and local payment methods integrated behind a single API.
Cross-border & multi-currency rails
FX-aware payment flows, local acquiring, and cross-border settlement built for global operators.
Crypto on/off-ramp integration
Fiat-to-crypto and crypto-to-fiat payment rails integrated into existing checkout and wallet flows.
Automated reconciliation
Ledger-matching engines that reconcile PSP settlement files against internal transactions automatically, flagging exceptions only.
Payment hub development
A central payment hub giving finance and product teams one dashboard across every PSP and rail.
Local payment method expansion
Adding region-specific rails — bank transfers, QR payments, mobile wallets — so checkout matches what customers in each market actually expect to use.

Our Approach
Our approach to development methodologies
Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your payment gateway integration project and your team in San Luis Potosí, Mexico.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so payment gateway integration priorities can change as you learn from users.
Kanban
Best for: Continuous delivery & support
A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.
Fixed-scope (Waterfall-style)
Best for: Well-specified builds
Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.
Lean MVP
Best for: New ventures
Build the smallest payment gateway integration release that proves demand, measure it with real users, then invest where the data points.
DevOps & CI/CD
Best for: Every project
Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.
Security-by-design (DevSecOps)
Best for: Regulated & high-value systems
Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.
