Quotes, deposits and progress invoices for building work

Quote the job, invoice the deposit, bill each stage and close with a final account. Every document is linked so nothing is billed twice or forgotten.

Sounds familiar?

  • Quotes in WhatsApp, invoices in Excel

    Nothing matches, and the client remembers the lower number.

  • Materials not recovered

    Extra bags of cement and a second trip to the supplier never make it onto the invoice.

  • Progress payments slip

    Stage two is done but the stage two invoice has not been sent.

How InvoiceWriteNow handles it

  • Quotation to deposit invoice

    Accepted quotation becomes the deposit invoice, then the progress invoices, all referencing the same job.

  • Materials and labour lines

    Itemise materials, labour and call-outs separately so clients see exactly what they are paying for.

  • Saved product lists

    Keep your standard items and rates so a quotation takes minutes on site.

  • Overdue tracking

    See which sites owe you and send reminders before the next stage starts.

Frequently asked questions

Can I invoice a deposit against a quotation?

Yes. Convert the accepted quotation and adjust the invoice to the deposit amount; the quotation number stays on the invoice.

Does it work on a phone?

Yes. InvoiceWriteNow is a web app that installs on Android and iPhone, so you can quote and invoice from site.

Can I add VAT to materials and labour?

Yes. VAT applies to the whole invoice at 15% when you are registered, and each line shows its exclusive amount.
