- Source authority
- Define which system owns product, price, stock, customer, order, fulfilment, return, supplier, tax, payment, and accounting facts. Make conflicts and stale data visible.
- Vendor compatibility
- Confirm exact product, version, market, licence, API or file access, events, writes, rate limits, sandbox, certification, support and commercial terms. Never infer compatibility from a name.
- Inventory and money
- Allocation, adjustment, price, tax, tender, refund, supplier invoice, settlement, and accounting writes need approved rules, bounded permissions, audit, exception handling, and reconciliation.
- Customer and operational policy
- The retailer and advisers own fraud review, consumer remedies, accessibility, privacy, pricing, promotions, tax, security, fulfilment, inventory truth, vendor management, and incident response.
