The customer signs the completion report from their Client Portal on their own device — not from the tech's phone. The tech finishes the job, the office authorizes it, and the customer signs from their portal whenever they get to it.
What if the customer never signs?
You don't have to chase them. After 3 business days, TradelyHQ closes it on its own so you can move on.
Can I still invoice?
Yes. Once the office authorizes the report, the work order is Completed and you can invoice right away. You don't have to wait for the signature.
