Frequently asked questions
- Is GJAM Invoice Generator really free?
- Yes — your first 5 PDF downloads are completely free with no signup. After that, a one-time lifetime license unlocks unlimited downloads forever.
- Can I import my Invoice Simple data?
- There is no automated importer (yet). The simplest migration is to copy your client and business details into GJAM once — they auto-save to your browser and never need re-typing.
