Service delivery proof, property, services
Proof of service delivery, so the work done is recognised.
Delivery, cleaning, condition report, repair, freelance assignment: prove that the service was delivered, on what date and in what condition. Proof your customer can verify themselves.
“It wasn't done.” “It wasn't in that condition.” “You didn't come on that date.” For a service provider, a dispute costs time, money and customers. Service delivery proof from Proov-It closes the discussion before it starts.
Photograph or film the result directly in the mobile app. The proof is dated, geolocated, anchored on a blockchain, and the PDF certificate can be verified by your customer, your client or an insurer. Attach the delivery note, the signed quote or the report: up to 20 files of 100 MB in a single submission.
For property professionals, it is the tool for condition report photos: move-in, move-out, damage, meter readings. Every photo carries its date and location, and any later edit can be detected.
Use cases
Service delivery proof: what a provider certifies.
Move-in and move-out condition reports
Every room, every defect, the meters: dated evidence that protects tenant and landlord alike.
Proof of delivery photos
The parcel handed over, its condition, the time and place. No more “never received” or “arrived damaged” disputes.
Cleaning and maintenance
The result after your visit, photographed on the spot. Your answer to late complaints.
Home repairs
The work done, the part replaced, the appliance working, all dated.
Freelance or consulting assignments
Deliverables, reports, mock-ups: prove delivery and the prior existence of your work.
Short-term rentals
The condition of the property before and after each stay, so the deposit is settled without argument.
Why Proov-It
Three reasons to adopt it.
Evidence the customer can verify
The certificate stands on its own: your customer verifies its integrity without an account or software. Trust is immediate.
Several files, one proof
Photos, videos, documents: up to 20 files of 100 MB per submission. A full inspection fits in one certificate.
Simple for the whole team
Your staff submit from their phones. You find everything by folder, customer or tag in your business workspace.
How it works
A proof in three steps.
No jargon, no technical skills. You submit or you capture, we certify.
Choose or capture
Documents, photos, videos. Or take a photo or video directly in the app.
Add the context
A comment, tags, a folder. To organise your proofs and find them easily.
Submit
You receive a PDF certificate attesting to the file's existence and integrity on the anchoring date and, for a capture made in the app, the geolocation recorded at that moment.
Does it hold up in court?
In France, where Proov-It is based, evidence may be brought by any means unless the law requires a specific form of proof (Article 1358 of the French Civil Code). The EU eIDAS Regulation, which applies in every Member State, adds a non-discrimination principle: an electronic timestamp cannot be denied legal effect solely because it is not qualified (Article 41). In 2025, the Marseille judicial court (20 March 2025, RG 23/00046) relied on blockchain timestamps, recorded by a bailiff and supported by other evidence, to establish the prior existence of creations. It is a first-instance decision: it does not make a blockchain anchor sufficient evidence on its own.
A Proov-It certificate can be produced as evidence; the court assesses its weight. We attest to the anchoring date, the integrity of the file and, for a capture made in the app, the recorded geolocation, not the truth of its content.
Frequently asked questions
What we are often asked.
Can the customer sign a photo condition report?
Yes. A proof can be sent for signature or validation by a third party, with acknowledgement of receipt and timestamped reminders.
Is a timestamped photo condition report valid evidence?
In France, evidence may in principle be brought by any means. A photographed, dated, geolocated and unaltered inspection is solid evidence, which the court assesses. It usefully complements the signed inspection report.
How much does service delivery proof cost?
One token per submission for an individual, whatever the number of files, with volume discounts. For businesses, plans with submissions included from €8.33 excl. VAT per month with yearly billing.
Where are the photos stored?
In France, at O2Switch, encrypted server-side. Remember to keep your originals too.
