Invoicing and payments built for tradespeople — estimate, approve, get paid.
SideWRK is a phone-first app for the money side of a trade business. Build an estimate on your phone, send it for approval, and get paid — by card, Venmo, Cash App, Zelle, or Apple Pay, with no merchant account and no per-invoice fee. It covers 30+ trades, from mechanics and appliance repair to cleaning, landscaping, and concrete, with real per-trade pricing built in. Free 14-day trial.
The interesting opportunity isn't making invoicing easier for tradespeople—it's becoming the fastest path from finishing a job to getting paid. I'd keep validating whether customers choose SideWRK because it replaces multiple payment tools or because it shortens the time between completing work and collecting cash.
You just described the design bet, honestly. The whole flow is built around leaving the driveway paid: write the estimate at the job, the customer approves and signs on their phone, and payment happens right there — card, Venmo, Zelle, or Cash App, no merchant account to set up. There's even a "request payment" link for guys who just text people for money.
On your validation question, I'll be straight: my sample size is tiny right now, so I can't claim customers over anecdotes. But the anecdote I trust most — when I show it to other techs in person, the moment that lands isn't the invoicing. It's "the customer signed and paid before I packed up the tools." Time-to-cash is the hook; replacing the pile of tools is just how it gets done. Watching closely whether that holds as real usage grows.
Appreciate the frame — "fastest path from finishing to getting paid" is going on the wall.
Appreciate the context.
Would be good to continue the conversation as you learn whether that signal holds with more customers.
