Entity relationship diagram

12 connected tables

Each box is a table — a tidy list your business keeps. The lines show how they link: every job knows its customer, every invoice knows its job. That link is what makes reports instant.

A complete data structure for plumbers, electricians, builders, and other trades. It connects customers, quotes, jobs, materials, time tracking, and invoices.

The transformation

From chaos to clarity.

The right data structure doesn't just store information. It eliminates the problems that cost you time and money every week.

Without structure

  • Unknown profitability

    Jobs completed without knowing if you made or lost money, until the accountant tells you three months later.

  • Quote accuracy drift

    Underquoting because historical job costs are buried in spreadsheets nobody can find.

  • Invoice delays

    Waiting weeks to invoice because job details are scattered across paper, email, and memory.

With the right model

  • Live job profitability

    See margin on every job as it happens. Materials, labour, and overhead tracked in one place.

  • Quote from data

    Build quotes from actual past-job cost data. No more guessing, no more money left on the table.

  • Invoice on completion

    Job closes, invoice generates automatically. Cash flow improves without chasing.
