A template is not about looking smart. It is about the customer finding the amount, the due date and the way to pay without hunting, because every second of hunting is a second in which they decide to deal with it later.
The order that works
Top to bottom, in the order a customer reads:
- Your business, top left. Name, address, phone, licence number.
- The word Invoice and the number, top right, with the issue date and due date directly under it.
- Bill to and service address, side by side.
- The work, as a description with amounts.
- Totals, bottom right, with the amount due as the largest thing on the page.
- How to pay, immediately under the total, not at the foot of the page.
- Notes, warranty and terms, last.
The common mistake is putting payment details in the footer. The customer has to scroll past the terms to find out how to pay, and some of them stop scrolling.
A worked example

Why that example is laid out that way
The call-out is shown and then credited. The customer sees they were charged for the visit and then not charged for it. Silently omitting it loses you the credit for a concession you actually made.
The description says where in the house. "Under kitchen sink" is what lets a customer match the invoice to a memory.
The due date appears next to the amount, not only in the header.
Payment comes before terms. The customer should not have to read warranty language to find out how to pay.
Numbering
Sequential, never reused, never restarted. INV-1043 is fine. Adding the date or the customer's initials feels organised and creates collisions the first time two jobs land on one day.
If you are moving from a spreadsheet, start the new sequence above your highest existing number rather than at 1.
Where a template stops being enough
A template produces a document. It does not know which documents are unpaid, does not number them for you, and does not chase anyone. That is the difference between an invoice and invoicing, and it is covered in plumbing invoicing software.
The free invoice generator produces this exact layout and prints it to PDF. Nothing is stored, which is fine for occasional use and the reason it is not a system.
Figures are illustrative. Tax treatment and licence display requirements vary by state.
