View flowFailure modes
What usually breaks in Square integrations
Real failure modes APIWORX sees in production and how the managed service handles them.
Variation-level inventory drift
Square treats variations independently for stock. We sync at variation level, not item level.
Refund posting timing
Refunds arrive after settlement. APIWORX matches and posts compensating GL entries.
Multi-location pricing overrides
Per-location prices need careful mapping. We preserve overrides per-location.
