- Buyer: a trades business, agency, consultant or clinic with 5-50 invoices a month and a stack of slow payers
- The workflow: overdue invoice -> reminder at 7 days, firmer note at 14, final notice at 30, then a flag for a human call
- Sell the outcome, not the tool: fewer awkward phone calls and cash arriving weeks sooner
- Ask Muse to draft three reminder emails in the client's voice: polite, firm, final - plus the trigger rules for each stage
- Build the flow in Zapier: invoice source (accounting app or a Google Sheet) -> date check -> send the right email -> log it
- Test with your own invoices first, then hand over a one-page runbook so the client can pause or edit a message
- Typical market rates: Upwork's Zapier cost guide lists $300-$800 for a single-workflow setup, $40-$90/hr for the builder
- A simple single-trigger workflow typically takes 1-2 days including testing, per Upwork's guide
- Zapier costs the client about $19.99/mo (Professional, annual billing, 750 tasks) or $0 on the Free tier under 100 tasks/mo - make clear that subscription is theirs, not yours
- Landing the first client is the work: most owners ignore cold pitches, so start with a business you already know and offer a free walkthrough of their overdue list
- A badly worded reminder can cost a client a relationship, so every email draft needs the owner's sign-off before it goes live
- No guaranteed income: one build is one payment, and repeat work depends on the client wanting more automations
