What stands up to scrutiny.
The proof is not a feature — it is the reason for the product. Six building blocks ensure it stands up to external scrutiny — technically and organisationally.
How the proof comes into being.
On-site check-in
NFC at the site instead of a QR code. Person-specific, no group check-in. Location context cannot be invented after the fact.
Server-side timestamps
The timestamp comes from the server, not from the device. Implausible transition times are detected.
Photo evidence from the app
Captured exclusively through the application. The original stays unchanged, edits remain traceable.
Complete change history
Every correction with a reason. What was changed, when and by whom stays fully visible.
Proof levels per service type
From none through scan, photo, before-and-after, measured value up to approval — defined per service type, not across the board.
Evidence file
One period as a document: services, people, times, photos, deviations. Matches the billing or audit period.
Not just “in case something happens”.
Four typical occasions where the proof counts immediately.
For site inspections
Hygiene, quality, board or authority — proof in seconds instead of binders.
For audits
IFS, BRC, HACCP self-monitoring. Period, area, document. No after-the-fact paperwork.
For service charge audits
Tenants' right to inspect records. The answer is a printout instead of a research project.
For contractual penalties
Fulfilment rate as the basis — traceable for client and contractor alike.
Contractual and legal requirements must be reviewed case by case. Taskey Share serves as proof of delivered work — it does not replace legal advice.
