Axiom³ vs UDATA — how they compare
UDATA is a long-established Quebec inspection software. Axiom³ is a complete inspection management suite — every step, from the client's first request to the signed report in their inbox, in one place.
The UDATA inspection software has been around for over a decade. UDATA claims to be used by more than 60% of Quebec inspectors. Axiom³ covers a different scope: a complete suite where the report editor fits into a continuous workflow — public intake form that auto-creates the project, APCHQ and AIBQ conventions and attestations generated and signed digitally, block-based editor with 1,800+ hand-vetted bilingual findings, automated bilingual client emails, no-account client portal, and per-inspector calendar sync. Here's how they compare.

Why choose Axiom³
Axiom³ is the complete inspection management suite for Quebec practices. The report editor fits into a continuous workflow designed to cover the full practice — from the client's first request to the delivered report and paid invoice.
A complete inspection management suite
From the moment a client submits the public intake form, Axiom³ creates the project, client, address and invoice records in one atomic transaction. APCHQ or AIBQ conventions and attestations are generated from that data and sent for digital signature via embedded DocuSeal. Bilingual emails fire at every milestone. The client receives their report through a secure no-account portal, no password to remember. The entire inspection cycle lives in one tool.
Learn more1,800+ hand-vetted bilingual findings
Every finding text in Axiom³ was written, reviewed and approved by a human who understands the BNQ 3009-500 standard and Quebec inspection law. This is a deliberate design choice: the inspector signs a legal document, and every word in it must come from a vetted source. The entire library is bilingual from a single source — pick a language at delivery and the report comes out in that language. It's an integrity position in service of professional accountability.
Learn moreBlock-based editor with Q/A logic and custom reusable blocks
The editor is structured component-by-component around BNQ 3009-500, with a question/condition system that matches findings to your answers. Save your own reusable blocks to a personal library, with version tracking — so the second inspection of a rare building type is faster than the first. Once you're comfortable with the flow, a full residential report takes 3–5 hours.
Learn moreAPCHQ AND AIBQ, both associations, fully automated
Both APCHQ and AIBQ conventions and attestations are auto-filled from the project data and sent for digital signature in one click. DocuSeal handles the signing, Resend handles the bilingual email workflow, and the signed documents land back in the client folder automatically. No template surgery, no manual follow-up — the entire signature journey is integrated into the client file.

Axiom³ vs UDATA — frequently asked questions
Direct answers to the questions Quebec inspectors ask when comparing these two tools.
Is the UDATA inspection software enough to comply with BNQ 3009-500?
Compliance with BNQ 3009-500 in UDATA depends on how you configure your templates. Axiom³ is structured around BNQ 3009-500 from the ground up, with required essential information fields, component-by-component section structure, and descriptive text rules baked in. You don't have to maintain a compliance template yourself.
Does UDATA handle APCHQ and AIBQ service agreements?
UDATA doesn't advertise automated APCHQ or AIBQ service agreement generation. Axiom³ generates both conventions and attestations automatically from your project data, sends them for digital signature through DocuSeal, and archives the signed document back to the client file — no separate tool required.
Can my clients book an inspection through UDATA?
UDATA doesn't advertise a public intake form for client booking. Axiom³ has a public no-account intake form that creates the project, client record, property address, and initial invoice automatically, so the job is ready before you ever pick up the phone.
Why would I switch from UDATA to Axiom³?
Axiom³ covers the entire inspection practice in one continuous workflow: client intake, APCHQ and AIBQ agreements, digital signatures, a BNQ 3009-500 report editor with 1,800+ hand-vetted findings, a no-account client portal, and calendar sync. One tool instead of several, one data entry instead of many re-entries.
Does Axiom³ come with a findings library like UDATA?
Yes. Axiom³ ships with over 1,800 bilingual inspection findings, each human-written and legally reviewed. You can also build your own custom blocks on top of the base library, version them, and override them per report. It's a living library that grows with your practice without relying on AI-generated content.
Will I lose my UDATA templates if I switch?
You don't have to. Axiom³'s custom block library lets you build your own reusable blocks, so any wording or standards you rely on can be ported over. The base library of 1,800 hand-vetted bilingual findings usually replaces most of what inspectors maintain in UDATA templates anyway — migration is typically about simplifying, not rebuilding.
