Start with one thing

A 48-year-old plumbing company in the Sierra Nevada · Home services and trades

Invoices typed from a photo, approved with a tap, landed in the books.

From a photo of a handwritten invoice to a typed one the owner taps to approve, plus four more projects, each fixing one thing they named.

What is happening now.

Luxin, an AI consulting firm, built, is building, or proposed this work. The status above says which.

  • Hundreds of handwritten invoices a year, each re-keyed into the bookkeeping software and then logged again by hand.

  • Billing catch-ups running eight to ten hours when it gets busy.

  • Paper work orders written out the night before, and rewritten mid-job when an urgent call comes in.

  • An invoice lookup that takes one minute on paper and ten in their software.

The numbers, with what they mean.

Every figure says where it came from. A problem found is not a result.

What is proposed.

  1. 01

    A photo of a handwritten invoice becomes a typed invoice. The owner taps approve, and it lands in the books and a searchable log.

  2. 02

    Replies to the morning email drafted in their voice, into Drafts, for them to read and send.

  3. 03

    Paper work orders typed once and sent to the plumber’s phone, so nothing is rewritten mid-job.

  4. 04

    A pricing brain that learns how the owner prices and drafts the quote.

  5. 05

    Customers nobody has called in 18 months get a note, and every happy customer gets asked for a review.

The tools it works inside.

Illustration of the pattern. Not a screenshot, and not real client data.

Nothing goes out without you.

Invoices, quotes and emails: nothing is sent until a person taps approve. When they trust it, they can switch any piece to automatic. Not before.

Tell me what’s eating the most time.

Thirty minutes, no deck. You describe how the work actually happens, and I tell you plainly whether there is something worth building.
