What has to be on an invoice?

At minimum: your business name and contact details, the customer, an invoice number, the date, an itemised description of what was done, the amount due, and how to pay. Trades that carry a license usually put the license number on it too, and in some jurisdictions that is required.

How soon should I invoice after finishing a job?

Same day where you can. The gap between finishing and invoicing is the single easiest lever on how fast you get paid, and it costs nothing to close.

Can I charge a late fee?

Usually, if you stated it before the work — commonly 1 to 1.5% per month. It has to be on the estimate or your terms, not introduced for the first time on an overdue invoice, and some states cap the rate. Check your own state before relying on it.

Invoice templates by trade

An invoice is the request for payment once the work is done — the document that actually gets you paid.

Send it the day the work is finished. Invoices sent within 24 hours get paid materially faster than ones that go out at the end of the month.

What every invoice needs

A due date, not just terms — "Net 14" means less to a homeowner than a date
Any deposit already paid, credited on the page so the balance is unarguable
Payment instructions the customer can act on without calling you
The estimate number it came from, so the customer can reconcile the two
