your ERP / your ERP sync issues

ERP sync stuck? Before you call — read the error. 90% of cases are things you can fix yourself in 2 minutes.

Common errors and how to handle them

ErrorCauseWhat to do
401 / UnauthorizedToken expiredSettings → Integrations → reconnect
422 / ValidationMissing customer detailsAdd tax ID / business ID / address on the customer record
2422 (your ERP)Wrong VAT calculationCheck vatType — must be 0 from POS
404 / Item not foundSKU doesn't exist in ERPCreate the item in your ERP first, or remove the line
500 / Server errorERP is downWait an hour and retry. Check your ERP/your ERP status pages
TimeoutSlow response from ERPRetry "Sync" — usually goes through on the second try

Where to see everything

Settings → Integrations → Sync queue. You'll see the list of stuck documents, the specific error for each, and an individual "Retry" button.

Massive sync that's stuck

If 20+ documents are stuck — that's a broader issue. Don't click "Retry" 20 times.

  1. Check if it's the same error for all of them — if so, there's a systemic cause.
  2. Fix the cause (e.g. your tax ID changed).
  3. Click "Sync entire queue" — Tamit will process them one by one.
💡 Tip your ERP sometimes silently suspends API access if your subscription lapses. Make sure you're paying them — not just Tamit.
