WOPA
Invoicing for tradespeople, right inside WhatsApp.
WOPA is a WhatsApp invoicing assistant for UK tradespeople. Message it like “Invoice Chris £850 for rewire” and WOPA drafts a PDF invoice, lets you review it, emails it to your customer, tracks what’s outstanding, and helps chase unpaid invoices. Customers get a normal email; you stay in WhatsApp. WOPA remembers all your customers when you need it.
Hey Product Hunt,
I’m launching WOPA because a lot of UK tradespeople still manage invoicing through a mix of WhatsApp, notes, spreadsheets, and memory.
WOPA keeps the workflow where the job already happens: WhatsApp.
You can message something like:
“Invoice Chris £850 for rewire”
WOPA drafts the invoice, lets you review it, emails the PDF to the customer, tracks what’s outstanding, and helps chase unpaid invoices.
The goal is simple: less admin after the job is done, without forcing tradespeople into another dashboard.
I’d love feedback from tradespeople, solo operators, and anyone who has had to chase invoices manually.
