The quote and progress certificate drift apart
AndCompta converts the complete quote into a reviewable draft. If you invoice by certificate or stage, create each document with its own scope; partial conversion is not automated.
Construction: work is billed in stages
A construction project is not a single sale. It is a series of progress certificates issued over months, with retentions, subcontractors, and materials arriving before they can be billed. The books need to follow that sequence.

The same three headaches
The three places where a construction company loses money are not on site—they are in administration.
Guarantee retentions need dedicated control
AndCompta does not automatically calculate or separate construction retentions. Record them using your accounting firm's policy and retain the supporting evidence; do not treat them as an ordinary overdue balance.
The subcontractor invoices late and incorrectly
The subcontractor's invoice is captured, read, and held for your review. It does not enter the books until someone approves it.
