You choose which tasks need a photo before they can be marked done, from a route stop to a plaster phase. Every photo carries who took it, when and where.
Every owner has had the conversation about what “done” means, more than once, with the same person. In PoolPath it is a setting on the task. If the after photo is required, the stop does not close without it.
When a customer says nobody came, the photo with its time and place is what proves your tech was there. The good ones already want that cover.
