How it works

From template to issued letter in three steps

1

Save your letter as a template

Write it in the editor, import it from Word, or start from the ready-made template library.

2

Fill in only what changes

Name, amount and date. Amounts are written in figures and words, dates in Gregorian and Hijri.

3

Issue it stamped and signed

It gets its reference number and verification code, and is archived as a PDF ready to send.

Features

Built for how our offices work

From letterhead and stamp to manager approval and incoming mail.

Reference numbers that never repeat

Automatic numbering across all your devices, even when issuing offline.

Electronic stamp and signature

Each company has its own stamp and signatories, plus signatures for parties and witnesses.

A verification code on every letter

The recipient scans it and sees the letter really came from you.

Several companies, one account

Each with its own letterhead, templates and archive. Switch between them in a tap.

Manager approval

The assistant drafts the letter; the manager approves it or rejects it with a reason.

A searchable archive

A full history of every letter, with its attachments and scanned signed copy.

Incoming mail and replies

Log what you receive, set a reply deadline, and track delivery.

FAQ

Frequently asked questions

Does it work offline?

Yes. After the first launch you can work and issue letters offline, and everything syncs to the cloud when you’re back online.

Do I need to download an app from a store?

No. Open the link in your browser and install it to the home screen on your phone or computer.

What happens when my subscription ends?

You get a 7-day grace period, then 30 days to view and download your letters without issuing new ones. The verification page keeps working for every letter you issued.

Can I bring my existing letters from Word?

Yes. Import the letter from Word, mark its variable fields, and it becomes a ready template.

How do I pay?

Transfer through Bankak and send the receipt on WhatsApp, and we activate your subscription right away.
