Is Osos Right for You?
In all transparency: Who the system is designed for, and who we don't recommend it to currently.
Suitable for You (Excellent Choice)
If your work depends on projects and branches, and you seek clarity instead of a clutter of useless buttons.
Contracting Companies and Multi-Branch Businesses
Why?Because your work requires knowing the details of every project (when did it start? how much profit and loss?) in addition to managing expenses and permissions across branches in one system gathering everything clearly.
Key Features:
Those Seeking E-Invoicing and Financial Management Without Headaches
Why?Because your goal is compliance with Zakat requirements and issuing invoices quickly, rather than drowning in complex screens and systems you don't need.
Key Features:
Not Suitable for You Currently
If you are looking for a crowded cashier for fast sales, work completely offline, or need a highly complex ERP.
Highly Complex Systems or Offline Work
Why?Because 'Osos' is a modern cloud system focused on simplicity, and does not suit those looking for an overly branched chart of accounts with dozens of levels or those requiring fully (offline) work.
Key Features:
Supermarkets Relying on Fast Cashier (POS)
Why?Because this type requires multiple terminal devices and local systems relying entirely on barcode readers and rapid instantaneous cash sales.
Key Features:

Direct API integration with Authority servers to send tax and simplified invoices automatically and instantly.


Frequently Asked Questions
Clear answers before you start — because we believe there is no room for ambiguity in numbers.
Absolutely. Osos integrates directly with the ZATCA (Fatoora) portal to automatically generate XML files, Cryptographic Stamps, and certified QR codes with zero manual intervention.
Because we built Osos around your actual daily workflow. We eliminated crowded screens, nested menus, and unused buttons. Every click serves a clear purpose, accelerating your tasks instead of slowing you down.
Every project acts as an independent Cost Center. You can allocate sales invoices and expense vouchers directly to a project, giving you a precise Profit & Loss (P&L) statement per project.
Legacy systems require manual ledger posting. In Osos, your daily administrative actions (billing, receiving cash) are automatically translated into flawless accounting data in real-time.
We offer clear tiers: a flexible Monthly plan for startups, and discounted Annual plans (Business & Enterprise) that unlock advanced ERP and multi-branch features.
