Once you know what you're collecting and where it's going, the last piece is making it as easy as possible.
John figured out what he sells, how people buy it, and how long they think about it. That told him what to collect.
He checked that it was legal to collect where he wanted to post it. Then he made the ask - and made it one tap.
But even with all of that, John was still doing it manually.
Remembering to send the first message an hour after finishing a job, then three days later, then a week out. For every customer. Forever.
Until he automated it.
Now the only thing John does is mark the job done. An hour later, the first message goes out. Three days later, the second. A week later, the third.
They stop the second somebody responds - so nobody ever gets nagged. And John gets a notification every time someone shares a piece of proof.
One decision about what he's collecting. One place he checked. Three messages he wrote. One evening to set it up. Then he never has to touch it again.
Same 400 jobs. More proof, more consistently.
