Common Questions

Questions & answers

Five honest answers about how INZO compares to Invoice Ninja for growing finance teams.

Invoice Ninja works for freelancers needing basic invoicing. INZO is built for businesses where billing connects to sales and contracts. When a deal closes in LIO or a contract signs in SIGI, INZO generates and sends the invoice automatically. Invoice Ninja cannot do this without Zapier.
Yes. INZO ships six native AI engines Invoice Ninja does not offer on any plan. Cash flow forecasting, client payment reliability scoring, AI escalation advice, AR aging recovery, OCR scanning, and payment behaviour analysis. All included on the core plan at no extra cost.
INZO sits inside WorksBuddy alongside seven other agents. A deal won in LIO triggers an invoice instantly. A contract signed in SIGI fires billing with all details pre-populated. TARO time logs pull into invoice line items automatically. No middleware or Zapier required. Invoice Ninja needs external connectors for every integration.
Significantly. Invoice Ninja sends standard reminders. INZO scores every client on payment reliability, ranks overdue invoices by recovery probability, and recommends the exact next action per client risk profile. Late payments drop because every overdue invoice gets a different, smarter response.
Both support multi currency invoicing. INZO applies conversion rates at send time and reports all revenue in your base currency automatically. Where INZO leads is what happens after the invoice is sent. AI forecasting, payment scoring, and AR recovery all work across every currency without manual reconciliation.

Stop letting revenue sit in invoices that no one is chasing
