Free purchase order generators are a reasonable place to start and it helps to know what they consistently omit. It is not the document, which they produce well. It is everything that happens afterwards, when deliveries arrive in pieces and invoices come in against lines, which is where the work actually is.
What you get
A tidy order with your details, the supplier's, a number, lines and terms, ready to email. For an organisation raising a handful of orders a month with deliveries that arrive complete, that is genuinely sufficient, and using one while the habits bed in is a sensible way to start rather than a mistake.
What you do not get
Ordered, received and invoiced quantities per line, dated revisions, and an open-order report. Without those, partial deliveries cannot be tracked, the accrual is rebuilt by hand and invoices cannot be matched against reality. Test it in five minutes: order ten, receive four, invoice four, ask what is outstanding.
The numbering trap
Free tools often leave numbering to you, which is where manual processes fail: two people raising orders at once, or a restored file, and a number gets reused. That makes two transactions permanently indistinguishable in every downstream record, and there is no retrospective fix. Control numbering from one place whatever tool you use.
Questions people ask about purchase order generator free
Is free good enough to start?
Often yes, particularly while you establish numbering, approval and receipt habits. Those habits matter more than the tool at low volume.
When should we pay for something?
When somebody starts a second spreadsheet to track what is outstanding, which is the system trying to exist.
What should we check before relying on one?
Numbering control and whether you can export what it holds. Both are cheap to check and expensive to discover later.
