PDF is not really a format you write an invoice in. It is the format you send one in, and the distinction matters. Whatever you compose in, the document that leaves your outbox should be a PDF, because it renders identically on the client's machine and cannot be quietly edited before it reaches their accounts payable team.
That second point is more practical than it sounds. An editable invoice is weak evidence in a dispute, and some finance departments will not process a Word or spreadsheet file at all because they cannot treat it as a fixed record.
The generator on this site produces a PDF directly, which skips the export step and the font substitution problems that come with it.
A photographed or scanned invoice cannot be searched or parsed by the client's finance system, which slows payment.
Something like invoice-0042-acme-ltd.pdf. "Document1.pdf" gets lost in an inbox.
Number, both addresses, dates, line items, total, payment terms and bank details.
Multi-page invoices need the invoice number and a page count repeated on every page.
Some "print to PDF" paths rasterise the page. The result looks right but the text cannot be selected or read by software, which is a real obstacle for larger clients.
If the PDF is generated on a machine without your font, the layout shifts. Embedding fonts, or generating the PDF server-side, avoids it.
It feels careful and it is genuinely counterproductive. Accounts payable will not chase you for a password, they will park the invoice.
In Word or Excel, use File then Export or Save As and choose PDF rather than printing to a PDF driver, which can rasterise the text. In Google Docs, File then Download then PDF Document. Check afterwards that you can select the text in the finished file: if you cannot, it has been saved as an image and should be redone.
No. It creates work for the person who is meant to pay you, and invoices do not usually contain anything that is not already in the email carrying them. If the content is genuinely sensitive, send it through a client portal rather than encrypting the attachment.
Not casually, which is the point. PDF editors exist, so it is not tamper-proof evidence, but it stops the accidental and opportunistic changes that an editable Word file invites, and it is what finance teams expect to receive.
Editable in Word or Google Docs, best when you want to change wording often.
Best when quantities and rates vary, because the arithmetic is done for you.
Good when you work across devices or want a colleague to see the same file.
The free generator fills in this structure, totals it and gives you a PDF, with no sign-up. If the same clients come round every month, Suitekore can send them without you opening anything.
