Consulting invoices are read by someone who did not hire you, usually finance. Write the lines so a stranger can tell what was bought and why it cost that.

Every invoice needs the same statutory core: a unique number, the issue date, both parties in full, a clear description of what was supplied, the amount before tax, the tax rate and amount, and the total due. That part is the same whatever you do for a living. What separates an invoice that gets paid from one that gets queried is how the specifics of your trade are written down.
Reference the engagement or PO number; finance departments route invoices on that alone.
Split fixed fees from session-based work so partial billing is straightforward.
Agree payment terms in writing before the engagement, then restate them on every invoice.
The generator is loaded with a plausible consultant invoice rather than an empty grid, so you can see the shape of a good one before you replace the numbers with your own. Nothing here is fixed, so change the wording, the quantities, the units and the rates.

Example figures in euro at a 21% rate. Switch the currency and the per-line tax rate in the generator. Billr does not assume where you are or what you owe.
Late payment is usually a process problem, not a client problem. Invoice on the day the work is delivered rather than batching everything to month-end; name a due date instead of writing “on receipt”; and make the payment details impossible to miss by putting them in the payment terms field, where every template renders them under the totals.
If you correct an invoice you have already sent, do not edit the original. Issue a credit note that references it and send a new invoice. That is what an auditor expects to see, and it is why Billr locks an invoice the moment it goes out.
The same core fields as any invoice: the word "invoice", a unique sequential number, the issue date and due date, your business details and tax number, your client's details, one line per item with quantity and unit price, the tax rate and amount, and the total due. The part consultants get wrong is the description column. Reference the engagement or PO number; finance departments route invoices on that alone.
Yes. The generator on this page needs no account and puts no watermark on the document. You can edit it, change the design and download as many PDFs as you like. A free account exists only so you can save the invoice, reuse the client and see when it is opened.
Yes. Over twenty currencies are available and every line carries its own tax rate, so VAT, GST, sales tax or no tax at all are all a matter of typing a number. Billr deliberately does not guess your local tax rules.
Agree payment terms in writing before the engagement, then restate them on every invoice. Beyond that: state the due date on the document, send it the day the work is delivered rather than at the end of the month, and keep an eye on what has gone past due. Billr flags overdue invoices for you and tells you the moment a client opens one.
