InvoiceAgent vs Invoice Ninja
Invoice Ninja offers a broad, low-cost invoicing platform with recurring billing, projects, time tracking, payment gateways, client portals, apps, and a self-hosted path. InvoiceAgent is more focused on reviewable PDF delivery, external time imports, send-time FX, and one operational queue.
Choose Invoice Ninja
Choose Invoice Ninja when price, a client portal, payment collection, platform breadth, or control over self-hosted deployment is central to the decision.
Choose InvoiceAgent
Service businesses that want WakaTime or Toggl imports, PDF test sends, scheduled delivery, reminder follow-up, and the latest available FX rate applied when the invoice is sent.
Timing-first invoicing
Schedule the invoice once. Weekend rules, reminders, recurring sends, manual-send overrides, and PDF delivery stay coordinated from one queue.
Live FX at dispatch
Draft early in the source currency. Let the final conversion happen when the invoice actually goes out.
Branding and time-tracking built in
Choose invoice templates, colors, fonts, logo treatment, and import billable hours from WakaTime or Toggl without adding another tool.
What this comparison is for
Freelancers and small businesses comparing an extensible invoicing suite with a smaller managed workflow for invoice preparation and delivery.
Here is the real tradeoff.
Choose Invoice Ninja if a free entry point, native time and projects, payment gateways, client self-service, customization, or self-hosting wins the decision. Choose InvoiceAgent if you want a smaller managed workflow for external time imports, testable PDF delivery, reminders, and send-time FX.
Why teams switch
You already track billable work in WakaTime or Toggl and do not want to recreate projects and timers in another platform.
Why teams switch

Side-by-side without the marketing fog.
Core audience

Offers live PDF preview, four Free or eleven paid templates, custom designs on paid plans, and Gmail, Microsoft, or SMTP sending on Pro and higher.
Payment collection

Connect supported gateways such as Stripe, PayPal, Square, or GoCardless and let clients pay through the portal.
Time tracking
Import approved WakaTime or Toggl entries and group them into client-readable invoice lines.
Track billable time and projects natively, then move completed task or project time into an invoice.
Multi-currency behavior
Draft in a source currency, apply the latest available FX rate at send time, and lock it into the PDF.
The hosted pricing page lists automatic currency conversions, while its broader workflow supports currency-specific clients and invoices.
Accounting scope

Adds vendors, expenses, inventory, P&L and other reports, with bank sync and e-invoicing on higher hosted plans.
Setup effort
A seven-day managed trial focused on invoice rules, delivery, reminders, and one send queue.
Hosted accounts can start quickly; self-hosting adds infrastructure, updates, email, backups, security, and support decisions.

A focused product and help path; validate the complete invoice workflow during the trial.
Web, desktop, and mobile apps, documentation and community support, integrations, an API on paid plans, and priority support on paid hosted plans.

Evaluation method
We compared the current public products across core audience, invoice creation, recurring schedules, reminder controls, PDF and email delivery, payment collection, time tracking, multi-currency behavior, accounting scope, setup effort, pricing, and support. We reviewed Invoice Ninja's official pricing, feature, portal, application, and pricing-update pages; we did not run a hosted or self-hosted account test for this update.
Pricing snapshot
Invoice Ninja lists a hosted Free plan for up to five clients with unlimited invoices, Pro at $14 monthly or $140 annually, and Enterprise from $18 monthly or $180 annually for up to two users, with higher user tiers. Self-hosting white-label licensing is listed at $40 annually. InvoiceAgent lists $24 monthly, $240 annually, or $12 once for one non-recurring invoice; it does not process client payments.
Check before buying: Hosted and self-hosted Invoice Ninja are materially different operating choices. Gateway availability and fees depend on the provider and country; e-invoicing, bank sync, users, branding, templates, and support vary by plan. Confirm the live matrix and your self-hosting responsibilities before switching.

Does Invoice Ninja include recurring invoices and payment collection?+
Yes. Recurring invoices, auto-billing, online gateways, and a client portal are listed across hosted plans. Automatic late-payment reminder emails begin on Pro, and gateway availability and processing fees depend on your provider and region.
Which product is better for time-based billing?+
Invoice Ninja is stronger when projects, timers, tasks, and invoices should live together. InvoiceAgent fits teams that already track work in WakaTime or Toggl and want approved entries to move into a controlled PDF and delivery workflow.
