Does SupaJack Construct raise invoices from payment certificates?
Yes. A progress invoice is raised from an approved payment certificate for the certified amount plus VAT and posted to the ledger in the same step. Without a certificate there is no invoice, except for small contracts that need no application, which require commercial approval and are flagged for review.

Why the certificate gate
Invoicing the claimed amount rather than the certified amount leads to disputes and credit notes. Tying the invoice to the certificate means the figure the consultant approved is the figure invoiced, and VAT follows the FTA's continuous-supply rules from the invoice date.
Advance recovery and retention
The certificate carries the advance recovered and the retention held. How VAT applies to retention is a contract setting that locks once the first invoice posts under it, so one contract cannot be billed two different ways.
What the finance team sees
Each invoice is numbered from a sequence, carries the certificate reference, and appears in receivables and the VAT return for its period without re-keying.

Worked example
A consultant certifies AED 820,000 for April with AED 41,000 retention and AED 82,000 advance recovered. The contractor raises the invoice from that certificate. VAT is charged on the certified value less the advance recovered, and the invoice posts to receivables and output VAT at once.
