Bill the percentage completed, with the retention, the advance and the variations already deducted.
Project billing in this trade is not an invoice, it is a certificate: what was completed, less what was already billed, less the advance, less the retention, plus the variations. Getting that arithmetic right is most of the job.
A certificate that reads the way a quantity surveyor reads
- 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
Progress entered the way the site reports it
- 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
Retention released for what it belongs to
- 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
The accounting underneath is not an afterthought
- 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
The numbers on the wall
Nineteen interactive financial reports, the collections dashboards — ageing, high-risk customers, critical overdue — and Odoo's Invoicing spreadsheet dashboard.
