Mesocyber FOS — a financial operating system
FOS connects the work of a business into one set of books. Each engine runs a part of the business; every engine feeds a central hub that produces the trial balance and financial statements.
Purchase & inventory
Purchase orders, goods receipts, stock movements and supplier returns.
Payables
Vendor bills, payments, withholding tax and MSME payment tracking.
Statements hub
Trial balance, profit and loss, balance sheet and cash flow from the engines' data.
Designed for real work
- Excel 2019 and Google Sheets, from the same build
- Sample data and a how-to sheet in every file
- Exceptions reviewed in each engine before anything reaches the books
- Staff entry files plus a manager's master workbook
- Country settings for tax and dates — not India-only
