Your point of sale,
already accounted for.
Sales flow in from the till, tender by tender, and the books are done by the time the shift is. Deep LithosPOS integration, plus daily syncs for the platforms you already sell on.
LithosPOS, live
sales, payments & returns become real documents
5 platforms, daily
Shopify, Square, Clover, Lightspeed, Loyverse
Double-post-proof
replays and retries can't duplicate revenue
The till and the ledger, one system.
OneBooks and LithosPOS are built to run together — the counter sells and the books write themselves.
- ✓ Real documents, not summaries — each sale, payment and return posts as a genuine invoice, payment or credit note.
- ✓ Tender-aware — cash, card and split payments land in the right cash or bank account.
- ✓ Returns handled — refunds post the correct reversals with the tender checked against the return.
- ✓ OAuth-connected — authorize once; no keys to paste or rotate.
- ✓ Built with LithosPOS — the deepest POS integration OneBooks offers, document for document.
One clean entry per selling day.
For Shopify, Square, Clover, Lightspeed and Loyverse, OneBooks posts a daily summary that keeps your ledger tidy and your IVA 23% return complete.
- ✓ Daily sales journal — revenue, IVA 23% and tenders summarized into one balanced entry per day.
- ✓ Tax done right — output IVA 23% from POS sales flows into your tax reports, refunds included.
- ✓ Refund-aware — returns net against the day correctly, even for orders from a previous day.
- ✓ Idempotent by design — retries and replays can't double-post a day, and re-syncs correct cleanly.
POS accounting — common questions
Which POS systems does OneBooks support?
LithosPOS with a deep, document-level integration — and daily summary syncs for Shopify, Square, Clover, Lightspeed and Loyverse.
How often do sales sync?
LithosPOS posts as you trade. The cloud platforms sync once per selling day as a single clean summary entry — and you can re-sync a day safely if something changes.
Will a retry or replay double my revenue?
No — every sync path is idempotent: a repeated push or an overlapping retry is recognized and rejected instead of posting twice.
Do POS sales appear in my tax reports?
Yes — output IVA 23% from POS sales, including refunds, flows into the same tax reports as your manual invoices, so your return covers everything you actually sold.
