WOPA

What it does

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.

WOPA helps UK tradespeople create invoice PDFs, email customers, chase unpaid invoices, and send payment reminders from WhatsApp.

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
