Daily sync Square sales,
counted right.
Connect Square and OneBooks posts a daily sales journal that books split tenders correctly and counts Sales tax exactly once per order — the two places POS accounting usually goes wrong.
Tax once per order
never once per tender on a split payment
Split tenders
cash and card portions land in the right accounts
One entry per day
revenue, Sales tax and tenders, balanced
Connect, map, and let the day post itself.

Authorize Square; OneBooks verifies each webhook delivery and rejects anything it can't authenticate.
Map tenders
Cash to cash, card to bank — split payments follow the same mapping automatically.
Sync daily
Each selling day becomes one balanced summary entry, re-syncable if something changes.
The split-tender problem, solved.
When a customer pays half cash and half card, naive integrations book the order's tax twice. OneBooks books the order once and the tenders separately.

Square integration — common questions
How are split payments booked?
The order's Sales tax is counted once; each tender portion posts to the account its payment method maps to — cash to cash, card to bank.
Per order or per day?
One summary entry per selling day. Order detail stays in Square; the ledger stays clean.
Can a retry double my revenue?
No — syncs are idempotent and re-syncs reverse before re-posting.
Does it handle refunds?
Yes — refunds net against the day's revenue, tenders and Sales tax.
