Try it. Who are you?
No account, nothing you tap is saved, no camera needed. It uses example answers; the real app uses your own photos.
Each one is a scripted walk through the app’s steps, using that trade’s real questions — and each shows you something different about how the check works.
Interactive demonstration — no real check runs, no record is created, and nothing you tap here is stored.
Everything else your account can do
The walkthrough above shows the part you’d use most. These are already in the app too — tap any one to read how it works.
- A quick nudge before you leave siteAdd a photo and a small chip can say it looks dark, blurry, too small or already added — about the photo only, never the work.
- Records for my insurerA printable list of your own active certificates for a period you choose, with no customer detail, to hand to an insurer, a broker or anyone who asks.
- Your account, locked downSign in with a passkey — your face or fingerprint — and sign out every device at once if you ever lose a phone.
- What happens to a record after it's signedNothing is overwritten: a correction is a new record, a withdrawal a dated notice, a building-code change a dashboard notice if it touches open checks; records are kept at least 10 years from issue.
- Equipment read off the data platePhotograph the plate and the brand, model, rating and serial are proposed for you to check onto the record.
- What you've built upCounts of your own work on your own dashboard — certificates signed, checks run, photographs recorded — as facts, never a score.
- Your archive is yoursDownload every certificate you have issued as a structured record, with the evidence photos attached to them, any time, in one file.
- Assist — guidance, never a certificateAsk about work you are looking at and get the provisions that apply, with no verdict, no certificate and only a short log kept; apprentices can use it when their trade shares its Assist allowance.
- My licence — what your classes coverDescribe a job and an AI model writes how it maps onto your classes and what belongs to another licensed trade, then start the job with those trades listed; NSW work also gets NSW rules.
- Home warranty certificate, looked upThe job's home warranty certificate number is looked up on the NSW HBC check register, which shows whether it is there and whom it is held against — never that cover is current.
- Jobs, enquiries, quotes and variationsCustomers enquire with photos, and the job holds the timeline, the notes, the quotes and the trade's own declared variation records.
- Records for this invoiceTick which of a job's own records an invoice relates to, and print a sheet naming each one's date, sections and verify link.
- Your NSW work address, checked against NSW heritage and hazard mappingSet an NSW work address and it is checked against NSW's own mapping — heritage, bush fire, mine subsidence, flood and landslide (some councils only); a miss shows nothing, which is not an all-clear.
- The handover packThe trade who owns the job picks which of its active certificates to collect behind one public link, each one still verifiable on its own.
- Organisations and seatsThe organisation pays and the individual certifies — every trade on the plan signs their own certificates personally.
- Apprentices capture, you certifyAn apprentice photographs on your jobs with their name on every shot, and you review and sign.Walk-through · Apprentices capture, you certify
Demonstration — scripted.
An apprentice asks to link to you — you don’t add them from your side. Accepting means taking on something real: taking them on means taking review responsibility for everything they capture on your jobs from that point on.
Every photo they take carries their own name on every shot, timestamped, so it’s always clear whose camera it came from. On the check, a button reading Use photos captured on this job brings their captures in as evidence for you to review alongside your own.
You alone answer the declaration questions and sign — an apprentice’s photograph can become evidence in your check, but only you can run checks and certify. The record is issued by you, the licensed trade, and it is your own record, not a statutory certificate.
Supervision. You need to satisfy yourself that you are complying with the supervision requirements that apply to the work on each job, in the state or territory where that job is. SoleyProof is not suggesting that any particular method of review, including looking through an apprentice's captures, will satisfy those requirements.
You take on an apprentice, and a few months later the arrangement ends. What happens to what they captured?See the link from the apprentice’s own side:
- An office manager runs the jobs — you signSomeone in the office runs the jobs, the enquiries and the invites, and never reaches the pen.
- Insurance and credentials in one placeInsurance expiry read off the trade's own certificate of currency (or entered by the trade), and NSW white cards, SafeWork and high risk work licences checked against the NSW registers.
- When an account goes unpaidThe records a job holds — timeline, variations, plans, invoices, notes and certificate photos, but not its messages or change history — assembled into one file to hand on.
- Plans, with the designer on the recordPlans carry the designer, drawing number and revision as fields that outlive the file, and a designer's DBP registration can be checked on the NSW register.
- The job as it stands, revisions in your nameInvite an engineer onto a job and they see it as it stands and, once you allow revisions and their NSW DBP registration is confirmed, push revisions in their own name — never certifying.
- Reviews screened, customers rated tooReviews are checked before they publish, low stars wait for a person to decide, stars count published reviews only, and trades rate customers in stars, averaged once three different trades have rated.
- Built for dead spots on site (needs an account)Photos upload one at a time as you add them, wait when there is no signal and carry on when it returns; a failed one has its own Retry.
- Send a variation for sign-off (needs an account)Send a recorded variation by link to the customer or the trade who engaged you, who sign it off or decline it with a note, no account needed.
- Is it just me? Service status (needs an account)The status page shows any known incident or maintenance notice and any licence or ABN connection the app has recorded as failing repeatedly.
- Your credential dates in your calendar (needs an account)Subscribe your phone's calendar to your own licence, insurance and white card dates.
- Download a copy of your account's records (needs an account)Download your account details, jobs, messages, notes and uploaded files in one file with a README of every part.
- Change your email yourself (needs an account)Change your sign-in email from your profile; the new address must confirm first, then we send a notice to the old one.
- Stop invitations, no login needed (needs an account)Every invitation carries a link that lets the person invited stop further invitations to their address, and allow them again later.
- A door for each side of the jobTrades sign up with an ABN, a licence and its issuing state; people hiring a tradie sign up free; building companies and developers are priced separately; apprentices with just a name; engineers with an optional DBP number; office managers only by invite.

A record is not a PDF that rots in an inbox
Most paperwork stops the day it is signed. This is what happens to a SoleyProof record for the years afterwards — and the rule underneath all of it is that the signed content of a record is not changed after it is issued, and a record is not removed quietly. A correction is a reissue and a withdrawal is marked on the record, so the original stays on record. Another trade’s later work is added as a dated note or a new record, so what was recorded stays readable. A change in the building code is flagged to a trade with an open check it touches; it is not written onto a signed record. Records are kept for at least 10 years from issue.
- The moment it is signed
Signed under a licence, on the latest register read
Signing relies on the latest register read of the trade’s licence. Where SoleyProof can read a state's register automatically (NSW, through the government's own interface), that read is the one signing relies on. Where it can't, a person at SoleyProof checks the state's public register by hand before that trade can sign anything. The certificate states how and when the read it rests on was made. That read must show the licence in force. A licence may be relied on at signing if it was read within the previous 120 days (or 14 days where a renewal is being processed). So the licence will not necessarily have been read on the day of signing, and it may have been suspended or cancelled since it was last read. It is not just a check from when they joined, and signing takes their authenticator code. The document carries a fingerprint of the record as stored, printed on its face.
The fingerprint is the useful part later: a customer’s paper copy can be compared with the fingerprint SoleyProof stored for the record. A match shows the copy carries the stored fingerprint; it does not test the other words on the page.
- From then on
Anyone holding it can check it
A reference code and a public page that shows who issued it, what it covered, when, and the outcome. No account, no password, no asking anyone’s permission.
- When another trade finishes work this one left
The record is annotated, not amended
Some work is deliberately left for the trade who comes next — flashing by the roofer, for instance. When that trade records their own work on the same job, a dated note appears on this certificate pointing at their record.
It reports that another record exists, by business, date and reference. It never says the work is finished — the platform has no way to know that, and says so instead of guessing.
- When the building code moves
Open checks are flagged; a signed record still says what it said
The National Construction Code’s publisher is watched for new editions, amendments and notices. When a clause SoleyProof holds changes, a trade with a check still open that cites or relies on it is told on their dashboard which document and which clause moved, and which of their open checks it sits behind.
The certificate is not rewritten and nothing is re-scored. A record already signed is not annotated or re-checked when the code moves, and a trade with no open check of an affected kind is not sent a notice. The notice follows a change to the clauses SoleyProof holds, not the publisher’s announcement. Work already checked was assessed against the rules in force at the time, and the notice makes no judgement about that work.
- If something needs correcting
Reissued — and the old one stays live
A correction produces a new certificate with its own number. The original does not vanish: it stays at its own address, kept for at least 10 years from issue, carrying a banner that says it was superseded and a link to what replaced it. The links run both ways.
The verdicts, the photographs, the assessment date, the client name and the site address are carried across frozen. A reissue corrects the document; it never re-judges the work, and it cannot quietly change an outcome.
- If the trade withdraws it
Withdrawn, and the withdrawal is part of the record
A trade can withdraw a record they signed. It is not deleted and the page does not go dark — it carries an unmissable notice saying it was withdrawn, by whom, and when.
The notice reports the withdrawal and makes no determination about the work. Someone holding the paper copy sees the notice the next time they check its reference code, which is the whole point of annotating rather than deleting. If the withdrawn record was itself a reissue, the earlier versions’ pages carry the withdrawal too.
Every step above is built and running today. Read what each one does (needs an account).
