Cheap OPR software: the 3 lowest-priced options in 2026
Updated 7 June 2026
Cheap OPR software lets you run the pre-reception inspection and snag-list management without an expensive subscription. The three cheapest credible options in 2026 are Kizeo Forms (15 €/user/month, forms-based), Builddar (25 €/licence/month, plan-based with EXE4/EXE8), and Finalcad/Orisha (≈ 29 €/user/month, with a limited free tier). Fieldwire offers a free tier up to 5 users. Price is not the only criterion: a compliant reception PV and a 10-year defensible audit trail weigh more than a cheaper subscription. Prices verified 7 June 2026, excluding VAT.

The cheapest OPR software: Kizeo Forms at 15 €
Kizeo Forms is the cheapest OPR software on the market at 15 €/user/month on annual billing. It is a generic forms engine offering templates dedicated to the OPR, snag-list management, and the reception PV, with photos, signature, and offline mode.
Its limitation comes from its nature: Kizeo fills in forms, it does not pin reserves on the plan. For an architect who inspects zone by zone and wants a structured OPR report tied to the drawings, a forms-based tool quickly shows its limits on complex sites.
The best price-to-compliance: Builddar at 25 €
Builddar is the cheapest dedicated plan-based OPR software, at 25 €/licence/month, with subcontractors free for life. It generates the OPR report (EXE4) and the signed PV de levée des réserves (EXE8) from data captured on-site, with no re-keying.
For 10 € more than Kizeo, the architect moves from a forms-based tool to a plan-based one compliant with the French workflow: each reserve logged in 30 seconds with location, trade, photo, and deadline; automatic assignment and reminders; PV generated in one click; an audit trail defensible across the 10 years of decennial liability.
That is the trade-off this comparison recommends: the criterion is not the lowest price, but the lowest price for a tool that produces a compliant PV and an audit trail that holds.
The free option to test: Fieldwire and Finalcad
Fieldwire offers a free tier up to 5 users, 3 projects, and 100 sheets, enough to test OPR and snag-list management on a small site before paying $39/user/month. Finalcad/Orisha also offers a free tier limited to 200 observations per project.
These free tiers are useful for evaluating a tool, not for running a portfolio of projects over time. Fieldwire remains field-first and is not built around the French EXE4/EXE8 templates: its PV is an exported generic report, not a native reception PV.
