Square

The Square integration posts one balanced journal entry per day — a Z-report — with net sales split by tax rate, the tax collected, tips where applicable, and the money received split by payment type into your cash and bank accounts.

Connect

1. Open Apps, select Square POS and choose the environment — Production, or Sandbox to test.
2. Select Connect Square and authorise in Square.
3. Review your locations; each active location is synced separately.

Map accounts

Before the first sync, tell OneBooks where each figure goes. Defaults are proposed; change them if you use custom accounts.

• Tender → debit account — every payment source (and card brand, if you split by brand) maps to a cash or bank account; a blank brand row is the catch-all for that source.
• Revenue, tax payable, tips and a default payment account for payments with no resolvable tender.

Any payment type without a mapping makes that day’s sync fail with a clear message — map it and re-sync.

The sync

• Runs automatically every hour and posts each completed day in the store’s timezone.
• Manual re-sync — enter a date range (or leave it empty for a catch-up of all unsynced days). A day that was already posted is reversed and re-posted, never duplicated.
• Each day’s status is listed under the connection: Pending, Posted, Failed (with the reason) or Skipped (no sales).

Accounting effect

Per day: Debit the mapped cash/bank accounts by payment type · Credit 4000 Sales Revenue (net, by tax rate) · Credit 2100 VAT Payable for tax collected · Credit 2400 Tips Payable for tips. Refunds reduce the same lines. The entry’s source type is POS summary, which makes it reversible as a unit.

Disconnect

Disconnect stops the sync and removes stored tokens; posted entries stay in the ledger.
