Know what CatInvoice is—and what it is not
It is an invoice maker, not a replacement for accounting or payment software.
| CatInvoice is a good fit when | Look for a larger platform when |
|---|---|
You want to make and send occasional or regular service invoices | You need recurring subscription billing or automatic reminders |
You prefer no signup and are comfortable keeping records on your device | You need cloud sync, team accounts, roles, or approval workflows |
You want a polished invoice without adopting accounting software | You need bookkeeping, bank reconciliation, payroll, or tax filing |
You want to download a PDF and send it through your own email | You need built-in card processing or a hosted customer portal |
