Payments and Checkout

Checkout and payment engineering: PSD2 and SCA with exemption handling, multi provider routing, local payment methods per market and reconciliation your finance team can audit.

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

Measured

Every step, before and after

Checkout funnel, five step legacy flow against a two step rebuilt flow

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.

Table 05. Method selection is validated against your own settlement data during discovery, not taken from a market report.

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.
