Next Invoice
For consultants

Clear, professional invoices for independent consultants

Consulting work is billed in different ways: by the day, by the hour, as a project fee or as a monthly retainer. Next Invoice lets you describe each one clearly and keep your client organisations and invoice status in one place.

Illustrative example of how consulting work can be described.

Fits the way consultants work

Day rates and hourly work

Label a quantity as days or hours and set your rate, with totals worked out as you type.

Monthly and retained work

Describe the period covered and the agreed service, so the client's finance team can match the invoice to the contract.

Client organisations

Keep full client profiles with their own invoice numbering options and a linked invoice history.

Status at a glance

Mark invoices Draft, Sent, Paid, Overdue or Cancelled and use the dashboard to see what is outstanding.

A layout your clients will take seriously

Start from the Classic Professional layout for a familiar format, or Modern Coral for a warmer one, then adjust fonts, colours and fields in the template builder. Add your logo and bank details and download a PDF.

Use the invoice notes for a purchase order number or payment instructions your client needs. Agree payment terms before the work begins and show a specific due date on every invoice.

  1. 1

    Logo and title. Your logo and a quiet title sit in their own band, apart from the detail below.

  2. 2

    Client and reference. The client's name leads, with the issue date and invoice number underneath.

  3. 3

    An accent on the amounts. The coral colour picks out the line totals while the descriptions stay neutral.

  4. 4

    Bank details. Payment details are set in the footer, ready to copy.

  5. 5

    A due date of its own. The due date has its own labelled slot, so it cannot be missed.

  6. 6

    Total due. The amount due, in the accent colour, closes the page.

Describe each kind of engagement

Group strategy sessions and follow-up work under their own section headers, so a single invoice can cover a workshop, a retainer and some ad hoc analysis without becoming a jumble.
