Invoices for the self-employed, from the hours you logged

If you work for yourself, Muster turns the hours you logged into an invoice for a client, with your mileage at HMRC's approved rate, numbered when you issue it and shared as a PDF from your phone. It also shows what is still owed.

Say how you work

When Muster asks how you work, say you are self-employed. The app follows: your week has no 39-hour threshold and nothing about the 48-hour limit, Reports shows what your invoices would charge, and a period ends in an invoice rather than a timesheet. See How do you work?

An invoice from your hours

New invoice drafts one for a client and the dates it covers:

Lines one per job, or one per day.
Hours at the client's own rate if you set one, otherwise yours.
Your own overtime, week by week, if you set a rule for it.
Mileage from Journeys: your own-vehicle drives on the days that client's hours are billed, ticked for you, and any other you tick. They are charged at your rate, or HMRC's approved rate if you set none (simplified expenses for vehicles): 55p a mile for the first 10,000 business miles in a tax year, 25p after.
Expenses, each with VAT on it or not.
VAT at the standard rate of 20%, only if you are registered and have given the number.

The draft shows every line, the net, the VAT, the total and when payment is due, 30 days unless you set your own terms. Nothing is numbered or kept until you press Issue invoice.

Issued means fixed

Numbered in order: INV-0001, INV-0002, and never changed after.
Nothing billed twice. An issued invoice's hours and drives cannot go on another one.
Never one you did not see. If an entry was edited or a drive measured since you looked, issuing is refused.
A mistake is put right with a credit note. CN-0001 cancels the whole invoice, and its hours and drives can then go on a new one.

Sent, and paid

Share as PDF makes the invoice into a PDF on your phone and opens the share sheet, to email it or save it. Mark as paid records the day the money arrived. Outstanding is what is owed out of what you have issued, and turns amber once any of it is past its due date.

Your invoicing cycle

By default your cycle is the calendar month, invoiced by the 1st, and Summary counts down to it. You can set the day it starts and the day you invoice by.

The steps are in the manual under Self-employed: Invoices.
