Every month, businesses pay hundreds for invoicing software they barely use. QuickBooks, FreshBooks, Wave — they all promise professional invoicing but charge premium prices for features most businesses don’t need.
What if you could get the same functionality — or better — for free?
Welcome to the world of open source invoicing.
The Invoicing Software Trap
QuickBooks Online: The Enterprise Price Tag

| Essentials | $55 | $660 | Estimates, 5 users |
| Plus | $80 | $960 | Inventory, 5 users |

- Total: $1,740/year
FreshBooks: The “Simple” Trap
FreshBooks markets itself as simple and affordable, but the pricing tells a different story:
| Plan | Cost/Month | Annual Cost | Users Included |
|---|---|---|---|
| Lite | $15 | $180 | 1 user |
| Plus | $28 | $336 | 5 users |
| Premium | $55 | $660 | 15 users |

Real-world cost for a growing business:
