Solution: A job-documentation and dispute-defense tool: (1) Guided capture — prompts the tech to photograph/video the existing condition BEFORE work (pre-existing damage, water pressure reading, panel state) and the completed work after, tied to the specific job and timestamped; (2) Condition notes — quick structured notes on what was already wrong, out of scope, or flagged to the customer; (3) Customer sign-off — on-site digital acknowledgment of pre-existing conditions and completed scope; (4) Callback-defense file — when a dispute arises, instantly pull the timestamped before/after evidence and sign-off; (5) Warranty/scope tracker — what's covered, what's not, when warranty expires; (6) Multi-trade tagging — document another trade's damage to deflect misplaced blame on shared sites. ICP: Service-trade contractors and small GCs who routinely get blamed for problems they didn't cause — a homeowner says the plumber 'killed my water pressure' when the cause was pre-existing, a customer demands a free callback for an unrelated issue, or a builder blames a sub for another trade's damage. Without documentation, these disputes cost free re-visits, refunds, reputation, and sometimes liability.

Purpose-built around liability and callback defense, not general project photos — the guided pre-existing-condition capture and on-site customer sign-off are the features that actually win disputes, and no incumbent frames or structures around them. The multi-trade blame-deflection tagging is novel for shared jobsites.

“Similar to how dashcams and rental-car/move-in condition-documentation tools created a market around 'prove what the condition was before, so you're not blamed.' This is a dashcam for service work — structured proof of pre-existing conditions and completed scope.”
