What posts, and how
- Sales invoices post one per PlanIt invoice number, with the customer as the QuickBooks customer and each line on your sales income account with the right VAT code. QuickBooks has no draft invoice; they post live.
- Payments taken at the counter post against the invoice into the account you mapped for that method. Account sales post the invoice only; the money posts when the account is paid.
- Credit notes post as a refund receipt for money paid back and a credit memo for the rest, applied to the original invoice.
- Voids here void the invoice in QuickBooks; its payments are removed first so nothing is left stranded.
- Customers and suppliers are matched by name, never duplicated. A name QuickBooks already uses for someone else gets your customer code after it.
- Payments received in QuickBooks against an invoice sent from here are recorded here within a few minutes: the invoice shows paid and the account balance comes down. A payment later deleted in QuickBooks is flagged, never silently unwound.
- Account balances from QuickBooks (switch it on under Overview) pulls open sales invoices QuickBooks holds that were not raised here onto the matching customer accounts, so credit limits count them while you move over.
Questions merchants ask
Does the connection expire?
QuickBooks renews its permission every time something posts. If the shop is quiet for more than about three months the page asks you to press Connect to QuickBooks again — nothing is lost.
What if I uninstall it?
The connection is deleted; everything already synced and the export history stay. The CSV files under Accounting remain available as a fallback throughout.
Can I run Xero and QuickBooks together?
No — one accounting system per business. Uninstall one before connecting the other; the add-on covers either.
