Where the money goes
Why this kind of app is expensive
Leaving a pet with a stranger only works if trust is designed in from the start — background checks, verified reviews, and a dispute process are not optional scope.
A booking calendar has to handle overlapping requests and a sitter's real-world availability without double-booking someone's dog.
Two-sided payments — charging owners, paying sitters after the job is done — add escrow-style logic most simple marketplaces do not need, and photo updates during a stay are what owners actually pay for.
The cheapest honest version of this idea is no background checks, manual booking approval, no in-booking photo updates. That lands nearer $20k–$47k.
