Construction Work Accounting & Measurement Books: How to Automate Them (2026)

Construction Work Accounting & Measurement Books: Automate the Computo→SAL→Payment Chain

Construction work accounting (contabilità dei lavori) — the measurement book (libretto delle misure), accounting register, summary and progress report (SAL) — is the bridge between what you estimated (the bill of quantities) and what you actually get paid. Under Italy's D.Lgs. 36/2023 it is the documentary basis of every payment, and done by hand it is one of the slowest, most repetitive and dispute-prone processes on any site.

Key points

• Manual work accounting costs a mid-size firm 15-25 hours/month per project.
• The bottleneck isn't measuring — it's re-transcribing the same quantities across the measurement book, register, summary and SAL.
• Automating the flow from site measurement to SAL means a quantity entered once feeds every document, and the SAL generates itself, consistent with the bill of quantities.
• This closes the computo → accounting → payment chain and links to DURC di congruità verification before each payment.
