Compliant by default,
not by afterthought.
Tax is calculated where it happens — on the document — and reported the way your authority expects. Issue FTA-style tax invoices with 5% VAT, keep your books in dirhams, and handle reverse charge correctly. Arabic and English invoices included.

Tax handled at the source.
Filing is only stressful when the underlying documents are wrong. Get tax right per line, per document, and the return becomes arithmetic.
- ✓ Per-line tax rates — each item carries its rate; mixed-rate documents just work.
- ✓ Inclusive or exclusive pricing — match how your market quotes prices; the math extracts the tax correctly either way.
- ✓ Reverse charge — self-assessed VAT 5% on applicable purchases and sales posts correctly, automatically.
- ✓ Tax position on demand — output vs input tax, net payable or receivable, per filing period.
- ✓ Credit and debit notes — returns reverse tax exactly, keeping the return tied to reality.
GST without the spreadsheet marathon.
GSTR filings assembled from your actual invoices and purchases — not from a re-keyed export.
- ✓ GSTR-1 and GSTR-3B — prepared from your real documents, with readiness checks before filing.
- ✓ CGST / SGST / IGST split — computed correctly by place of supply for the reports.
- ✓ HSN/SAC on items — carried onto documents and into the filing detail.
- ✓ Export for your filing flow — take the prepared figures to your portal or practitioner.
ZATCA Phase 2, actually built in.
E-invoicing that clears with the authority in the background — validated against ZATCA's own sandbox.
- ✓ Signed UBL e-invoices — cryptographically signed XML with the QR code printed on the invoice.
- ✓ Clearance and reporting — standard invoices clear, simplified invoices report, automatically and asynchronously.
- ✓ Credit notes as e-invoices — corrections follow the compliant path too.
- ✓ Device onboarding managed — CSID issuance and renewal handled inside OneBooks.
Tax & compliance — common questions
Does OneBooks support tax-inclusive pricing?
Yes — choose inclusive or exclusive per business. The engine extracts or adds VAT 5% correctly either way, per line, so documents match how your market actually quotes prices.
Is reverse charge supported?
Yes, end to end: reverse-charge purchases post the self-assessed tax and its input credit automatically, and reverse-charge sales are handled correctly on documents and in reports.
How does GSTR filing work in India?
OneBooks prepares GSTR-1 and GSTR-3B from your actual invoices and purchases, with readiness checks that catch missing data before you file, and exports the prepared figures.
What do I need for ZATCA Phase 2 in Saudi Arabia?
A OneBooks account and your ZATCA onboarding details. Device onboarding, XML signing, QR codes and clearance all run inside OneBooks — invoices you send are cleared e-invoices.
