How Does Scaftra Track Proof of Completion?

How do you prove the work was done right when the owner disputes it months later?

Scaftra scores how well each room and trade is documented, assembles immutable proof packs from field photos and sign-offs, and blocks billing certification on an unproven project.

The problem it solves

In finish-trade construction, the GC gets paid for work the owner can dispute months later: 'you never measured that,' 'the cabinets came in damaged,' 'nobody signed off on the install.' The defensible answer is evidence captured at the moment work happened: field-measure records, delivery verification, before and after photos, a completion inspection, and a client sign-off. When that evidence is scattered across phones and folders, it is not there when the dispute lands.

Why it matters

A proven job survives a chargeback, a lien fight, or a warranty claim. An unproven one does not. The product stance is Proof, Not Promises: every room and trade carries a running score of how well the work is documented, so a project manager can see before billing where the file is thin and fix it while the crew is still on site.

Common mistakes

How it works

1. Capture evidence in the field

   Crews upload before, during, after, issue, and sign-off photos, which attach to the inspection and the room's proof items.
2. Score the room

   Each room gets a documentation score from a config-driven engine, with penalties for missing specs, missing field verification, and missing proof.
3. Roll up the trade

   A weighted meter combines field measure, delivery, photo proof, completion, client sign-off, and punch into a per-trade readiness score.
4. Seal a proof pack

   Billing and client-share assemble an immutable snapshot of the evidence at a point in time that cannot be edited after publish.

How Scaftra does it

Scaftra runs the full proof spine. A config-driven per-room documentation score starts at 100 and subtracts penalties for incomplete specs, missing field verification, and missing proof, with thresholds coming from per-company rule tables rather than hardcoded numbers. A weighted per-trade Proof Meter rolls up field measure, delivery verification, photo proof, completion report, client sign-off, and punch clearance, and caps a trade meter when its rooms have thin paperwork. Proof packs are immutable JSON snapshots: once published they are frozen, and a pack cannot be published below a passing score. Critically, proof gates the money: pay application certification runs a proof and reconciliation check plus lien-release clearance before generating the invoice. This is built and live.

Key capabilities

• Per-room documentation score: A config-driven engine scores each room on specs, field verification, and proof, with thresholds set per company.
• Weighted trade proof meter: Field measure, delivery, photos, completion, sign-off, and punch roll up to one readiness score per trade.
• Immutable proof packs: A published proof pack is a frozen snapshot of the evidence; it cannot be edited after the fact.
• Proof gates certification: Pay app certification runs a proof and reconciliation gate plus lien clearance before any invoice is generated.

Benefits

• Disputes, chargebacks, and warranty claims meet a documented file instead of a scramble.
• Thin paperwork surfaces before billing, while the crew is still on site to fix it.
• Billing cannot certify on an unproven, unreconciled project.

Who it's for

• Project managers on finish work.PMs who need to see where a room's file is thin before they bill it.
• GC owners exposed to disputes.Owners who get paid for work the homeowner can dispute and need the evidence on file.
