Administration for plumbers: invoice right after the urgent job

Plumbers

You record the hours, trips and parts of a job with the client straight away. From them you make one invoice, and can send it the same day if you like.

01

A plumber works in a rhythm of short jobs: a leak, a blockage, a tap that needs replacing. Each job is small, but there are many, and each comes with hours, a trip and parts. The risk is not in the big assignment, but in the many small ones that never get passed on.

02

SmartWerk fits this way of working by not asking too much. You do not need a quote, contract or project. You record the job, make an invoice from it and keep track of who still has to pay.

Where it goes wrong in practice

  • Urgency with little time for paperwork

    You are standing in the cold in a crawl space. The administration only follows at home, and by then you have lost details.

  • Parts you buy on the spot

    A coupling, a trap, a length of pipe. Often you pay yourself and pass it on later.

  • Private clients who pay late

    A small invoice easily sits there. Without follow-up the amount disappears into the noise.

  • Fixed prices you keep retyping

    Call-out charge, an hourly rate, a standard unblocking. Retyping them each time costs time.

Example — fictional

A plumber with three jobs in one day

Example: a plumber replaces a tap in the morning, clears a drain around noon and repairs a leak in the afternoon. After each job he records hours, trip and parts.

At the end of the day he makes three invoices, each from the data of the job. Two weeks later he sees that one is unpaid and sends a reminder.

Frequently asked questions

Do I need a quote for an urgent job?

No. You can also invoice a job directly. A quote is optional.

Can I save call-out charges as a fixed line?

Yes. With Products & services you record call-out charge and hourly rate once and use them on invoices.

How do I send a reminder?

You send a reminder before or after the due date from the invoice list.

Can I enter private people as clients?

Yes. A client can be a company or a private person.

SmartWerk is invoicing and administration software for self-employed people, not a full accounting package and not a replacement for your bookkeeper or adviser.
