Daily sync Square sales,
counted right.
Connect Square and OneBooks posts a daily sales journal that books split tenders correctly and counts TVA 20% 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, TVA 20% 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 TVA 20% 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 TVA 20%.
