Computo Metrico and Accounting Software: PriMus, STR Vision CPM

What a Computo Metrico Program Has to Do

A computo metrico estimativo lists every work item with the quantity measured from the design and the unit price from a price list (prezzario); the total is the estimated cost of the works. A plain computo metrico stops at quantities; the estimativo multiplies them by unit prices. The software has to load price lists (Italian regions publish theirs free as open data under Annex I.14 to Legislative Decree 36/2023), hold the measurement rows behind each quantity or read them from an IFC model, build new unit prices through price analysis, and export in a format the other party can open. Public works add a fifth job: the accounting documents of the execution phase, from the measurement book to the final account.

Verified Comparison

Only what vendors state on their own pages. "On request" means there is no public price, and we have not estimated one. Prices checked on 28 October 2026. Only Namirial states VAT treatment, in the page's structured data rather than its text: €690 excluding VAT. The other vendors do not say.

STR Vision CPM Is Now TeamSystem Construction CPM AI

TeamSystem states that STR Vision has become TeamSystem Construction, with the same features and level of service. STR joined the TeamSystem group (Pesaro) through the 24OreSoftware acquisition announced in April 2014. The product is now called TeamSystem Construction Project Management AI; CPM stands for Construction Project Management. It covers price analysis, public-works site accounting, SAL and payment certificates, includes the DEI price-analysis database and an AI agent that turns PDF estimates into editable XLS or CSV files, and its QTO module imports IFC models, updating the estimate when the model changes. Its Cantieri App, connected to TS CPM, handles daily site reports and the site journal from phone or tablet. Pricing is a custom quote based on company type, users, modules and integrations.

Public-Works Accounting and BIM: The Legal Anchors

• Accounting documents. Annex II.14 to Legislative Decree 36/2023, art. 12, lists the site journal, measurement books, accounting register, SAL (sent to the RUP, who issues the payment certificate) and final account, plus an optional register summary and weekly lists for time-and-materials work. Not every program declares every document; ACCA, for example, covers the site journal with a separate product, usBIM.gdl.
• Open formats. Under comma 10, accounting is kept with digital programs that use open, non-proprietary formats, so as not to limit competition between technology suppliers. If the works director is external, the RUP must accept the software beforehand. No single product is mandatory.
• Measurements and small works. Comma 11 says the measurement book must be based on measurements taken on site in the contractor's presence. Comma 11-bis allows simplified, invoice-based accounting for works under €40,000. Both come from art. 92 of Legislative Decree 209/2024. Our Italian guide covers works accounting and the measurement book in detail.
• BIM threshold. Under art. 43, from 1 January 2025 contracting authorities must use BIM for new works and interventions on existing structures with an estimated cost above €2 million. Art. 15 of Legislative Decree 209/2024 raised the threshold from €1 million. Works on listed heritage buildings follow the EU works threshold (art. 14(1)(a)) instead, and ordinary and extraordinary maintenance is excluded unless the works were previously done with BIM.
• Formats in practice. XPWE is ACCA's PriMus format with published specifications; Pitagora and Namirial Regolo import it. SIX is an open XML price-list format that STR introduced in 2004; in 2012, 01net reported that it had become the standard for exchanging data between price-list publishers and their customers. SINTEL is Lombardy's e-procurement platform, not a file format.

Cases That Change the Choice

• Private work only: the Annex II.14 documents are not needed, and the free tools cover estimate, price list and quote.
• External works director on a public job: the RUP has to accept the software before accounting starts.
• New works or interventions on existing structures above €2 million: the contracting authority works in BIM, so the estimating software needs to import IFC.
• Several people on the same job: a hardware key (PriMus desktop) or single-PC protection (Regolo) limits use to one workstation at a time; you need more licences, a PriMus Classic second copy (requires an active POWER PACK subscription), a multi-user server licence (CONCANT Standard) or a cloud version (PriMus online, TeamSystem, Digi Corp MOSAICO 360).
• Tender specifications (capitolati): ACCA sells them as a separate product, PriMus-C, which imports the general data, the quadro economico (project cost breakdown) and the category structure from PriMus. It is on offer at €149 (VAT not stated, price checked on 28 October 2026) plus the AmiCus subscription required to buy it, and the one-month trial contains only demo templates. TeamSystem lists capitolati among the functions of CPM AI, Blumatica passes Pitagora's estimate data to Blumatica CSA (a separate product), Namirial includes capitolato templates in Regolo, and Digi Corp links CONCANT to its CAPITOLATI module.
• Exchanging files: agree the format first. XPWE is read by PriMus, Pitagora and Regolo; regional price lists come as open data.

What Is a Rule and What Needs AI

Multiplying quantities by prices, carrying measurements from the book to the register, the SAL and the payment certificate, and reading quantities from an IFC file are rules. Reading a PDF estimate, matching free-text descriptions to price-list items and reading photographed site measurements need an AI model. New prices, measurement checks with the contractor and signatures stay with the works director. That is why an AI copilot with human review fits estimating work better than an autonomous agent.

Where to Start

1. Write down what you must deliver: an estimate and quote for private clients, or the Annex II.14 documents for public works.
2. Ask which formats your counterparts use (XPWE, SIX, spreadsheets) and test them during the trial.
3. Download your region's open-data price list and check that the program imports it.
4. Redo a closed job in the free trials: 30 days for PriMus, 14 for TeamSystem Cantieri, one month for Edificius; Pitagora and CONCANT LT are free.
5. Compare costs last: licence, required subscriptions, add-on modules and the number of workstations.

The step after the estimate, turning it into a client quote, is covered in fast construction quotes.
