Admin systems, Melbourne

Software that takes the admin off small businesses.

Offsider finds the repetitive admin eating your week, then builds the one thing that takes it off you.

For plumbers and other trades first. You use it before you pay for it. Runs in your phone's browser, nothing to install.

A short look at the example

Six screens of a made-up plumber's week. Then click around it yourself.

The whole thing, start to finish

About 1 minute, no sound. The real screens, step by step: a made-up plumber, every name and figure from the demo.

The business on these screens is made up. Yours starts blank.

Built for the rules

Built for the rules you work under

Victorian rules change. The builds check them for you, and keeping them up to date is part of looking after it.

  • Every trade

    No card surcharges

    Visa, Mastercard and eftpos surcharges are banned. Invoices never add one, and card fees go into your prices.

  • Home building work

    Deposits on home building work

    The deposit is kept inside the legal limit for domestic building work, which changes with the size of the job. The limits can change by regulation from 1 December 2026, and keeping up with them is part of the monthly.

    Tax invoices that hold up

    Larger tax invoices need the buyer named or their ABN. It stops the invoice until they are, and a business not registered for GST never sends a tax invoice.

  • Plumbing and gas

    Compliance certificates on time

    Plumbing jobs over the threshold, and some gas and drainage work at any size, need a compliance certificate. It flags the job and counts down the five days to lodge it.

  • Plumbing and gas

    Gas hot water from March 2027

    A broken mains gas hot water unit in an existing home has to be replaced with an electric one. The quote offers the heat pump option before the customer asks.

How it works

How a project starts

  1. Step 1: A 15-minute call.

    Free. We ask where your hours go. We do not pitch.

  2. A gloved hand at an open switchboard, circuit breakers and coloured wiring

    Step 2: A one-page sheet.

    We fill it in with you on the call. You keep it, whatever you decide.

  3. Gloved hands with a wrench on the pipework under a sink

    Step 3: We build first.

    You use it on your own business. You pay only once it has earned it.
