A few things people ask.
Do I need the other apps to use Invoice?
No. Invoice works on its own. When Books, HR, and POS arrive, you can add them later — your customers and team carry over.
How are payments processed?
Through Stripe. You connect your own Stripe account and payouts land directly in your bank. ZipOS doesn't hold funds.
Can I send invoices in different currencies?
Yes. Each invoice can be issued in its own currency, with per-customer defaults.
Can I export my data?
Yes. Customers, invoices, and documents can be exported at any time. Your data is yours.
Is there a free plan?
Yes. The Free plan is genuinely free — no credit card required to get started.
Can my team use it too?
Yes. Invite teammates with per-company roles. The Business plan adds multiple companies under one account and advanced permissions.
