When A4 is the right size for a duplicate invoice book
A4 measures 210mm by 297mm, the size of a sheet of printer paper. In a duplicate invoice book that gives you about twice the writing area of A5, and the question is whether you need it.
What the extra room buys
- Lines. Ten or twelve item lines instead of five, so a job with parts and labour fits on one set instead of running onto a second.
- Legible handwriting. Bigger boxes mean fewer invoices that have to be deciphered later.
- Room for terms and notes. A panel for payment terms, a signature line and a note about the next service all fit without crowding.
- It files flat. A4 fits a lever arch file, an accountant's folder and a scanner without special handling.
When A5 is the better tool
If most of your invoices are two or three lines, A4 is a lot of paper to carry for white space you will not fill. A5 fits a glovebox, a toolbox and a back pocket, and it is cheaper per set. Plenty of businesses carry A5 invoice books on the van and keep A4 in the office for the bigger jobs.
What to put on an A4 layout
Use the width. Put the description across the left two thirds and quantity, rate and amount in narrow columns on the right, so the totals line up down the page and the eye can add them. Keep your logo and details in the top third, the numbering top right, and leave the bottom right for the total, where people look for it.
Ordering
Ours are printed to order in two part and three part sets, with your logo and details, sequential numbering and free delivery in Ireland.
