The Trusted Gulf Tax Engine
ZATCA Phase 2 ready · Built for the Gulf
From the till
to the tax return.
One system that raises the invoice, signs and clears it with the tax authority, posts it to a real ledger, takes the goods out of stock and carries all of it into your VAT return.

One system, not five that talk to each other
A document, end to end.
Most businesses stitch this chain together from a billing package, an e-invoicing gateway, an accounts system, a till and a spreadsheet. Every join is a place where the invoice, the XML and the ledger line quietly stop matching. V4G has no joins, because it has no parts.
- 01
Raise
A template that matches the supply: standard, simplified, export, asset, margin scheme.
- 02
Sign
UBL XML, cryptographic stamp, hash chained to the invoice before it, QR on the face.
- 03
Submit
Clearance for a standard invoice, reporting for a simplified one. The response is stored.
- 04
Post
Ledger entries, tax accounts, the customer's balance and the stock, in one transaction.
- 05
Report
Statements, aging, margins and the VAT return, drawn from those very same rows.
Everything in one place
Five bodies of work. One login.
E-invoicing & ZATCA
Onboarding from inside the app, signing, clearance and reporting, the QR, the submission log and certificate expiry alerts.
Documents
Sales, purchases, exports, imports, assets, credit and debit notes, proformas and quotes, emailed as PDF and XML.
Accounting & tax
Chart of accounts, ledgers, five financial statements, VAT returns, aging and statements of account.
Operations
A real till, barcode and QR scanning, shelf labels, stock and materials, swaps, staff and payroll.
The platform
Business intelligence, roles and audit, themes, dark mode, the mobile app and built-in help.

01
Clearance, reporting, and the difference.
Onboarding to production happens inside the interface, with the compliance checks run for you. Standard invoices are cleared before the customer gets them; simplified ones are reported. Every response ZATCA sends back is kept.
- UBL 2.1 XML, signed with your cryptographic stamp
- Invoice hash chained to the one before it
- QR on every face, with the full nine tags on simplified invoices
- Certificate expiry warnings on the dashboard and by email
- A sandbox and a training mode to rehearse on, safely


02
Twenty-two forms, because the tax treatment differs.
A template is not a layout. It decides which fields are required, how VAT is computed, which accounts are posted to and what the document is called on the return.
Promote a quote to an invoice in one click, email any document with its PDF and XML attached, and open the PDF straight after saving.


03
A real chart of accounts. Real statements.
Every sale, purchase, payment and payroll posts itself to a double-entry ledger. The statements and the VAT return are drawn from the very same rows, so they always agree with the documents.
Complies with International Financial Reporting Standards (IFRS)



04
A till, not an invoice form with big buttons.
Touch-first tiles, hands-free scanning, items sold by weight, cash drawer shifts and a receipt that is a real simplified tax invoice. It even sounds right: every action has its own tone, so a cashier works without looking.
- Barcode and QR scanning, including the phone's camera
- Generate product codes and print shelf labels in EAN-13, Code 128 or QR
- Stock and materials, expiry dates, adjustments and stock swaps
- Staff records and monthly payroll that post to the ledger


New · v4g AI
Ask your books a question.
An assistant that answers from your own data, strictly read-only and only within what each user is allowed to see. Connect the provider you already trust: Claude, OpenAI, Gemini or a model on your own server.
05
Arabic is not a translation layer.
Every screen, report and printed document exists in both languages, properly right to left. The language belongs to the user, so an Arabic-speaking cashier and an English-speaking accountant share one system, each in their own. Drag the slider.


Made to look like yours
Nine colour themes or your own two colours, with light and dark modes derived for you.

Who may do what
Fine-grained roles and a full audit trail of who did what, and when.

Help, inside the product
163 searchable topics in both languages, open to every user.
On the phone
A native Android app: fingerprint sign-in, camera scanning, Bluetooth receipt printers. On iPhone, the full system runs in Safari.
Built for the whole Gulf
Six regimes. One engine.
Saudi Arabia, the UAE, Bahrain, Kuwait, Oman and Qatar, with pan-Gulf supplies, per-emirate places of supply and export documents in the buyer's currency.
Real screens from a running installation
Take the tour. Drag, scroll, click.
What you get
Your data. Your choice of server.
The invoice, the XML and the ledger. Finally the same document.
In a language your staff read, on a server of your choice. Try it now, nothing to install.
