Combium: bank drafts, from paper to data

In Tunisia the bank draft (lettre de change / traite) is still a core B2B payment instrument, and it is still mostly handled by hand: drafts are filled in on official forms, printed, carried around and tracked in spreadsheets.

Combium is my own product, available in French and Arabic.

Drafts must print exactly on the standardized forms. Existing paper drafts must enter the system without manual typing. Several companies share one platform without ever seeing each other's data. And people need to know, every day, what is due.

Capture: a photo of a draft is parsed with OCR into structured fields.

Print: a high-precision print workflow positions every field on the official form.

Core: a multi-tenant data model with financial reporting per company.

Notify: an automated daily digest over WhatsApp and SMS, with alerts before due dates.

Isolation between companies is part of the data model, not a convention.

Digests go to the messaging channels people already read, instead of a dashboard nobody opens.

Print-ready drafts in one step, fewer typing errors, and a daily view of what's due for every company on the platform.
