Invoicing guides
Straight answers to the invoicing questions that come up when you bill your own customers — written for people running the work, not a finance department.

Two guides that the rest of this section keeps referring back to. If you have never had to put a bill together before, read them in this order.
- What to include on an invoiceThe complete list, element by element — and a clear line between common practice and what the rules where you trade actually require.
- How to invoice for servicesHow to describe work someone cannot hold, price it in a way that survives questions, and send a bill that gets paid without a phone call.

Quoting work
Sending an invoice
Have an invoice to send this afternoon rather than a question to answer? The free invoice generator builds one in your browser and hands you the PDF, with no account and nothing saved afterwards. If you want to know what belongs on it before you start, the invoice templates cover that trade by trade.
Looking for the app rather than the reference material? The invoice app pages cover how Invoice Tiger fits different kinds of work, and the review research covers what people write about invoicing apps once they have used one for a while.
From finished job to sent invoice
Invoice Tiger creates professional invoices and estimates on your iPhone, without an accounting system underneath them.
