Payments and checkout
Where architecture turns into revenue
A checkout has to satisfy the shopper, the payment scheme, the regulator and your finance team at the same time. Most checkouts are built for one of those four. We build for all of them and then measure the result step by step.
- Strong customer authentication with exemption logic, so low risk orders are not challenged unnecessarily
- Payment provider routing with automatic failover when an acquirer degrades
- Local payment methods per market, including the wallets and instalment products that decide conversion
- Guest checkout, address autocomplete, saved cards and one page flows where they measurably help
- Reconciliation to the cent, with settlement, fee and refund data landing in your finance system

Coverage
Methods, providers and the rules behind them
Payment mix is a market by market decision driven by data, not by which provider has the best integration guide.

01
Compliance without theatre
PCI DSS scope is kept to SAQ A by keeping card data out of your systems entirely. Where a business requirement forces a wider scope, we say so and price the consequence.
02
Fraud that does not block good orders
Rules and scoring tuned against your own chargeback and refusal data, with a review queue rather than silent rejection, and a monthly report on false positives.
03
Finance can close the month
Settlement files, scheme fees, refunds and chargebacks reconciled automatically against orders, with exceptions raised as tickets instead of spreadsheets.
