Connecting your ERP — your ERP, your ERP, your accounting system
Tamit doesn't issue invoices itself — it sends the data to your ERP, and the ERP is what produces a legal document with an official number. Without an ERP connection, you can't issue a tax invoice.
Which ERP is right for you
| Provider | Good for |
| your ERP | Larger businesses, inventory management, multiple warehouses |
| your ERP (your accounting system) | VAT-exempt / small businesses. Simple and cheap. Requires the Best plan |
| your accounting system | your ERP's brand name — same thing |
How to connect
- Settings → Integrations → ERP.
- Pick a provider, enter your API key + password (your ERP) or token (your ERP).
- Click "Test connection" — you'll get a green confirmation or a specific error message.
- Pick your business number / primary warehouse (your ERP only).
- Save. Sync of existing invoices begins in the background.
What you can't do
- You can't connect two ERPs at once. Pick one.
- You can't issue a "local" invoice — it has to come from the ERP.
- You can't cancel an invoice that's already been sent to the ERP. Only issue a credit note.
- your ERP requires the Best plan (not the regular one) to get API access.
⚠️ Heads up
If you opened books this year in a different system — don't connect it before you've fully exported. Document numbers have to be continuous across the entire tax year.
💡 Tip
Check the sync after an hour: Settings → Integrations → "Sync status". If you see errors, see
ERP sync issues.
