Questions you might have
Short, honest answers. If something is missing, the tools speak for themselves. Open one and try it.
Is it really free?
Yes. No trial, no signup, no credit card. The tools run in your browser and we don't charge for any of them.
Do I need an account?
No. There's nothing to sign up for. Open a tool, use it, close the tab. Your data never leaves your device.
Where is my data stored?
Nowhere by default. Everything happens client-side in your browser. We don't run a backend that stores your invoices, SKUs or addresses.
Can I use it for my real business?
Yes. The invoices, packing slips and labels are designed to be production-grade. Plenty of sellers run their whole back office on tools like these.
Does it work in my currency / country?
Pick your currency from the selector in the top bar and the tools follow. HS codes and shipping labels are designed for international use.
How is this different from a paid SaaS?
A paid SaaS bundles 50 features you don't need. Osmo Tools gives you focused, single-purpose tools that don't try to become your operating system.
Stop fiddling with spreadsheets. Run your back office.
