POS Migration Checklist: How Busy Retail Teams Avoid Inventory Drift
Most POS migrations fail for one reason: teams validate feature lists instead of daily workflows.
Why migrations underperform
- Inventory and invoicing are treated as separate systems.
- Mobile checkout is added late and breaks reconciliation.
- Returns are tested last and expose data gaps.
The one-day workflow test
1. Receive and label new stock (including variants).
2. Run in-store and mobile checkout.
3. Process at least one return/refund.
4. Complete end-of-day stock and accounting handoff.
If any step needs manual patching, the stack is not production-ready.
What to measure
- Time per workflow
- Number of manual corrections
- Stock delta between expected and counted inventory
- Quality of bookkeeping export
Red flags
- Split catalog behavior across channels
- Unreliable return/inventory movement
- Reconciliation dependent on spreadsheets
Final check
The best POS decision is the one that removes end-of-day cleanup, not the one with the longest feature list.
