Plumbers and electricians

Invoice from the van, before you leave the job

Call-out, parts, labour, done. A clean PDF invoice sent from your phone while the client is still standing next to you gets paid a lot faster than one sent on Friday night.

Sounds familiar?

  • Friday night admin

    A week of jobs invoiced in one sitting, from memory, with parts missing.

  • Parts markup lost

    Receipts in the cubby hole never make it onto an invoice.

  • "Send me the invoice" becomes "which invoice?"

    Without a number and a due date, chasing is guesswork.

How InvoiceWriteNow handles it

  • Saved products and rates

    Call-out fee, hourly rate, common parts: pick them from a list.

  • Works on mobile

    Installable on Android and iPhone; create and send from the job.

  • Certificate references

    Add the COC or compliance certificate number to the invoice notes.

  • Paid or not, at a glance

    Mark invoices paid from the bank notification and see what is still open.

Frequently asked questions

Can I create an invoice on my phone?

Yes. Install the app from your browser and it works like a native app on Android and iPhone.

Can I keep a list of parts and prices?

Yes. The products catalogue stores parts, rates and call-out fees so you pick them instead of typing.

Do I need to be VAT registered?

No. Turn VAT off and the invoice is a plain invoice. Turn it on when you register and the tax invoice fields appear.
