What it does

Compliance that runs in the background

Your team keeps working in ERPNext as usual. The Possy Fawtara app handles the rest.

Sends on submit

No exports or uploads. Submit in ERPNext and the rest runs in the background.

Checks before it sends

Missing VAT number, CR, HS or ISIC code? You’re told before submitting.

B2B, B2C and notes

Full tax and simplified invoices, credit notes and debit notes.

OTA QR on your invoice

The official QR code is saved on each invoice and printed with it.

Status and one-click retry

See Sent, Accepted or Failed on every invoice, with the reason.

Multi-company

Separate settings for each company. Works on ERPNext v15 and v16.

How we set it up

From install to go-live

Four clear steps, done with you, usually within a few days.

01

Install

We take a full backup of your ERPNext first, then install and activate the Possy Fawtara app. It usually takes under an hour, and your team can keep working.

02

Data mapping

We connect your company to ConvergeX and set your defaults: VAT and CR numbers, item types, ISIC and HS codes, governorate and credit note reasons.

Each company gets its own settings, so groups with several companies are fully supported.

03

Sandbox testing

Before anything is real, we test your actual invoice types in the ConvergeX sandbox: tax and simplified invoices, credit notes and debit notes.

Every invoice must come back Accepted before we switch you to live.

04

Go-live

We switch your company to the live environment. From then on, every invoice you submit goes to the Oman Tax Authority automatically.

The official OTA QR code is saved on each invoice and printed with it.
