Comparing Quotation Expert and Invoice Ninja for small business invoicing. We break down features, pricing, offline support, ease of use, and which app works better for different types of businesses.
Overview
Both Quotation Expert and Invoice Ninja are popular choices for small business invoicing — and both offer generous free tiers. But they're built for different types of users, and the right choice depends on your priorities.
This comparison covers everything: features, pricing, ease of use, mobile experience, offline support, and who each app is really designed for.
Quick Summary
Choose Quotation Expert if: You work on Android, need offline access, want a full business management app (not just invoicing), or prefer simplicity over feature complexity.
Choose Invoice Ninja if: You're comfortable with more technical software, want self-hosting, need a client portal, or have advanced time-tracking requirements.
Feature Comparison
Invoicing and Document Creation
Both apps cover the core invoicing workflow well — create, send, track, mark paid.
Quotation Expert goes further in document breadth. It handles the full document lifecycle: quotations, proforma invoices, invoices, receipts, delivery notes, purchase orders, and bills. All documents are linked — convert a quotation to a delivery note to an invoice in one workflow. PDF export is included on the free plan with no watermarks.
Invoice Ninja has strong invoicing with more options for customisation (multiple PDF templates, extensive branding controls). It also includes time tracking and project management features that Quotation Expert doesn't currently offer — useful for agencies and hourly-rate freelancers.
Winner: Quotation Expert for document workflow breadth; Invoice Ninja for customisation and time tracking.
Mobile App and Offline Access
This is where the two apps diverge significantly.
Quotation Expert was built mobile-first. The Android app works fully offline — you can create, edit, and PDF-export any document without an internet connection. Everything syncs to the cloud automatically when you reconnect. This is a genuine competitive advantage for contractors, field service teams, and anyone who works away from their desk.
Invoice Ninja has mobile apps for iOS and Android, but offline functionality is limited. The apps require an internet connection for most actions.
Winner: Quotation Expert — it's not close if offline access matters to you.
Business Management Features
Quotation Expert includes a broader set of business management tools beyond just invoicing:
Invoice Ninja focuses more tightly on client billing and project management. It has expense tracking but doesn't include payroll, inventory, or bank reconciliation.
Winner: Quotation Expert for all-in-one business management.
Pricing
Quotation Expert:
Invoice Ninja:
Winner: Both are competitively priced. Invoice Ninja has a slight edge on the Pro tier if you have many clients but low document volume. Quotation Expert's free tier is more generous on documents.
Self-Hosting
Invoice Ninja is open source and can be self-hosted on your own server. This is a significant advantage for businesses with strict data sovereignty requirements or developers who want full control.
Quotation Expert is cloud-hosted only (with offline sync to the Android app). No self-hosting option.
Winner: Invoice Ninja for self-hosting.
Ease of Use
Quotation Expert has a deliberately simple interface. Creating your first invoice takes under two minutes with no learning curve. The mobile and web interfaces are consistent and clean.
Invoice Ninja has more configuration options, which means more power — but also a steeper initial setup. The interface has improved significantly in version 5, but it can still feel complex for users who just want to send invoices quickly.
Winner: Quotation Expert for ease of use and speed of setup.

Final Verdict
For the majority of small business owners — especially those on Android or in the field — Quotation Expert offers the better out-of-the-box experience. It's simpler, covers more ground (inventory, payroll, tax), and its offline Android app is a genuine advantage.
For freelancers, agencies, and technically inclined users who value open source and advanced billing features, Invoice Ninja remains a compelling choice.
Both are free to start. The best approach is to try the one that sounds most relevant to your workflow — you'll know within 10 minutes whether it fits.
