A home-services business

Orders that book, confirm and file themselves.

Every online order used to be re-typed into accounting, confirmed on WhatsApp by hand, and logged in a spreadsheet. We connected the tools so each order flows through all of them on its own — and customers get reminders that bring them back.

The challenge

Order admin ate two to three hours a day. Confirmations went out late, invoices lagged, and nobody had time to follow up past customers — so repeat business leaked away.

The solution

When an order lands, the workflow creates the invoice in accounting, sends a WhatsApp confirmation with the booking details, logs the job to the master sheet, and schedules a service reminder that goes out when the customer is due again.

The workflow we built

  1. Catch the order. Web, WhatsApp and phone orders all enter one pipeline the moment they arrive.
  2. Invoice & confirm. The invoice is created in accounting and the customer gets an instant WhatsApp confirmation.
  3. File everything. Every job logs itself to the master sheet — schedule, amount, status, all current.
  4. Bring them back. Due-date reminders go out automatically, turning one-off jobs into repeat bookings.

The results

  • Manual order entry disappeared entirely — two to three hours a day back.
  • Repeat bookings rose 32% once due-date reminders started going out on time.
  • Around HK$14,000 of admin cost saved every month.
