The weekly check.
WHY DO IT
To catch payments that succeeded without updating your site.
HOW
Export transactions from your gateway for a period Compare against paid orders in your shop Investigate anything appearing in one and not the other
WHAT DISCREPANCIES MEAN
Payment without an order: webhook failure, or an abandoned checkout that still charged
Order without a payment: manually marked paid, or a test order
FOR PAYMENTS WITHOUT ORDERS
Find the customer, fulfil the order, and fix the webhook.
That customer paid and received nothing.
HOW OFTEN
Weekly for an active shop.
Monthly at minimum.
WHAT ELSE TO CHECK
That settlement amounts match transaction totals less fees That refunds are recorded on both sides
WHY THIS MATTERS COMMERCIALLY
Every unfulfilled paid order is a complaint, a chargeback and a lost customer.
Most shops never reconcile and never know.
WHAT TO RECORD
Discrepancies found and what caused them.
