Bill the percentage completed, with the retention, the advance and the variations already deducted.

✓Original contract value, variation orders, revised price, cumulative progress
✓Less previous progress, less advance recoupment, less retention, less penalties
✓Previous progress counts cancelled certificates that still carry a posted invoice, so nothing is billed twice
✓Every figure shown both against the contract and against progress to date

✓By percentage or by quantity, kept in step with each other
✓Re-priced lines carried as a revaluation rather than silently restated
✓Approval returns a deduction preview first, showing the split across the contract and each variation, before anything is posted

✓Main-contract retention and variation retention tracked apart
✓Release raises its own credit, against the right source
✓Three roles: raise and submit, approve, and configure

✓Nineteen interactive financial reports with drill-down — profit and loss, balance sheet, cash flow, ledgers, aged receivable and payable
✓Collections with promises to pay, disputes, payment plans and escalation rules
✓Assets with depreciation schedules, lock dates and recurring entries
✓Qatar chart of accounts and bilingual Arabic and English invoicing
