Integrations
Your store, connected to QuickBooks Desktop or Sage 50 U.S.
CartSpan® brings orders from the store you run today into QuickBooks Desktop or Sage 50 U.S. on its own. For stores that accept it, it sends stock back. Every store below uses the same engine underneath, so the accounting works the same way whichever you sell on.
- Orders as often as every 15 min
- Books checked for stock changes every minute
- One price, any store, Amazon at no extra charge
Amazon stock goes in batches, at most every 30 minutes. Kits counted from their parts, and a few other stock options, update on your scheduled refresh instead. How stock updates work →
