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.
