Money in, orders out, books that balance.
Payments, tax, and shipping are where integration mistakes cost real money. We wire gateways, tax engines, and your logistics partners into the store so every order is charged correctly, taxed correctly, shipped on time, and reconciled without a spreadsheet.
What does payments & logistics integration cover?
Everything between the customer paying and the box arriving: the payment gateway that charges the card, the tax engine that gets US sales tax right, the warehouse or 3PL that picks and ships, and the tracking that flows back to the customer. We integrate each piece cleanly and make sure the numbers reconcile at the end: what the gateway paid you matches what the store sold.
The money and delivery rails we wire.
Payment gateways
Cards, wallets, and the payment methods your customers expect: integrated cleanly, tokenized, and PCI-minded.
Tax engines
US sales tax calculated correctly at checkout through Avalara or Anrok: multi-state rules handled by the systems built for them.
Shipping & 3PL
Orders flow to your warehouse or 3PL automatically, and tracking flows back to the customer without anyone chasing it.
Returns that flow back
When a return happens, the refund, the restock, and the books all update: no orphaned credits, no ghost inventory.
Reconciliation
Payouts matched to orders automatically, so finance stops reconciling by spreadsheet.
Failure alerts
A failed charge, a stuck order, or a broken webhook raises its hand instead of silently losing revenue.
Correct at checkout. Correct in the books.
A store that charges wrong, taxes wrong, or ships late doesn't get a second order.
Discovery → Build → Certify → Scale
A senior-led delivery model built for revenue-critical commerce: predictable and transparent.
Discovery
We map the workflow, the constraints, and the compliance surface before a line of code.
Build
Senior engineers ship in two-week sprints. You see working software, not status decks.
Certify
Security and compliance are tested as we go (ADA/WCAG, PCI DSS, SOC 2 controls), never bolted on at the end.
Scale
We harden, instrument, and hand over, or stay on as your embedded product team.
Questions buyers ask us first
The ones your customers and your business need: major US gateways and wallets, and marketplace-grade providers when split payments are involved. We'll recommend the fit for your model in the strategy session.
We architect payment flows so card data stays out of your scope: tokenized and gateway-handled. For continuous PCI DSS support and evidence, that's our Managed Support & Compliance service, and the two pair naturally.
Through a tax engine built for it: we integrate Avalara or Anrok so calculation is accurate across states and you're ready for filing, instead of maintaining rate tables by hand.
Yes: if it has an API or a feed, we can connect it. Orders flow out automatically, tracking and stock levels flow back, and exceptions get flagged to a person.
Cross-border (multi-currency, localization, and international tax) is an add-on we build when a US brand expands. We'll tell you honestly what it adds in scope before you commit.
