Example planDog-walking bookings and payments

Summary

A booking site for a three-walker dog-walking business: owners book and pay for walks, walkers see their day, and the owner gets a weekly payout report. Estimate 30–56 agent hours, or 72–126 by hand. The biggest unknown is whether walks are priced per dog or per visit.

Estimate: 🤖 30–56 h; 🧑 72–126 h
Features: 3
Tickets: 5

Open questions

1Are walks priced per dog, per visit, or both?
2Do owners need to approve each walker, or can any walker take any booking?
3Is Stripe acceptable for payments and payouts?

Risks

1Recurring bookings with holidays and cancellations are easy to underestimate.
2Walker payouts depend on Stripe Connect approval for each walker.
