Bill · a WhatsApp bookkeeper for UK shops

Let Bill work your till.

A quiet bookkeeper for your shop. Runs on your phone. Tracks your till. Never asks you to type. Speak a sale, snap an invoice — Bill handles the ledgers, stock and VAT in the background.

Add Bill to your home screen — works on iPhone, Android and desktop. No App Store.

The Bill web dashboard — sales, vendors, low stock and recent activity for a UK shop.
WhatsApp chat: photograph an invoice and Bill reads it — £128.04 from Halford Electrical Supplies.
  • Built for UK shops
  • HMRC Making-Tax-Digital ready
  • Encrypted, UK-hosted

You didn’t open a shop to spend Sunday night with a laptop, a shoebox of receipts and a VAT deadline. Bill takes that off you.

How it works

Three ways in — whichever is fastest.

🎤

Speak it

Voice-note Bill the sale, the payment, the invoice. Bill writes it up and confirms before the next customer.

📸

Snap it

Photograph supplier invoices, card receipts, bank transfer screenshots. Bill reads them and files them.

📊

See it

Bill sends the day’s books at 8 PM. Or text “reports” any time for today, this week, this month.

Two ways to use Bill

Capture on the floor. Review on the sofa.

Capture in the moment.
