BillingNow and Invoice Ninja solve overlapping problems but have different centers of gravity. BillingNow is a focused AI-assisted billing workspace. Invoice Ninja is a broader small-business platform with a strong free tier, projects, time tracking, quotes, and a client portal.

|---|---|---|
| Entry price | $9.99/mo | $0 free plan; Pro $14/mo |
| AI billing assistant | Yes, documented by vendor | Not a core positioning feature |
| Receipt/supplier invoice scanning | Yes, vendor documents AI extraction | Expense and vendor tools; different workflow |
| Projects + time tracking | No built-in time tracking documented | Yes, included |
| Quotes/proposals | Estimates and quote workflow | Quotes/proposals with approval |
| Recurring billing | Yes | Yes |
| Client portal | Payment/document workflow varies | Documented branded client portal |
Choose BillingNow if your priority is focused billing automation
BillingNow is the cleaner fit when you want to create invoices, track expenses and payments, capture receipts, send recurring invoices, and use AI assistance without adopting a large operational suite.
Choose Invoice Ninja if projects and time tracking matter
Invoice Ninja is the stronger match when your billing starts with tracked time, project tasks, proposals, or a client portal. Its free plan also makes it easier to test with real clients before paying.
The practical test
Create the same sample client in both products. Send a quote, convert it to an invoice, record a partial payment, schedule a recurring invoice, and follow up on an overdue balance. The product that makes that full sequence easier is the better match for your business.
