Quick Comparison

TL;DR

Invoice Maker is a straightforward, form-based invoice generator with 500+ templates and mobile apps. It's a solid choice for simple invoicing without bells and whistles.

Eonebill is an AI-first invoice platform that generates invoices from a plain English description, covers 6 document types (Invoice, Contract, Proposal, Estimate, Receipt, Expense), and includes a credits rewards system — all starting free with 5 invoices per month.

If you're a US freelancer who invoices clients, Eonebill's AI automation saves more time than any template library. If you just need to fill out a PDF form, Invoice Maker's 500+ templates have you covered.

What Is Eonebill?

Eonebill is an AI-powered invoice and business document platform built for US freelancers and small businesses. Instead of filling out templates by hand, you describe your work in plain English and Eonebill generates a complete, professional invoice — ready to send in seconds.

Eonebill covers 6 document types:

• Invoice — AI-generated from a plain English description
• Contract — AI-generated service agreements and NDAs
• Proposal — AI-generated project proposals

• 14 languages supported
• 90+ templates with AI auto-fill (rapidly expanding to 300+)
• Free plan: 5 AI invoices per month

Pricing Comparison

Eonebill's free plan gives you 5× more invoices than Invoice Maker's free tier — and they're AI-generated, not just template fills.

Template Comparison

Invoice Maker wins on quantity: 500+ templates vs Eonebill's 90+. But quantity isn't everything.

Eonebill templates are AI-enhanced — when you select a template, the AI pre-fills line items based on your industry and client history. Templates are organized by profession (freelancer, consultant, contractor) and industry (photography, construction, IT, catering).

Eonebill is actively expanding its template library from 90 toward 300+ throughout 2026, prioritizing high-search-volume industries.

AI Comparison: Eonebill's Key Advantage

This is where the comparison becomes one-sided.

Invoice Maker has zero AI features. You pick a template, type in your numbers, and download. If you invoice clients regularly, that's the same manual work every single time.

Eonebill's AI is native, not an add-on. Describe what you did — "photography session for Acme Corp, 4 hours, plus $200 equipment rental" — and Eonebill generates a complete, formatted invoice with line items, tax calculation, and your payment terms.

The same AI engine generates contracts ("freelance web development for Client X, $5,000, Net 30") and proposals ("social media management for Q2, $2,500/month").

For a freelancer billing 10+ clients per month, Eonebill's AI saves hours of administrative work that Invoice Maker simply can't touch.

Document Type Comparison

Invoice Maker covers 2 document types. Eonebill covers 6. If you're running a freelance business, you need more than just invoices.

Mobile App Comparison

Invoice Maker has native iOS and Android apps. Eonebill does not yet have a mobile app (the web app is mobile-responsive).

If mobile-only invoicing is your hard requirement, Invoice Maker has an advantage here — for now. Eonebill has indicated mobile apps are on the roadmap.

Credits and Rewards System

Eonebill's Credits system lets you earn credits for activity:

• Sign up: +50 credits
• First invoice: +30 credits
• Refer a friend: +100 credits
• Daily login: +5 credits

Credits can be redeemed for bulk document exports, custom branding, and AI feature add-ons. Invoice Maker has no rewards system.

Final Verdict

Choose Invoice Maker if:

• You need a simple, no-frills invoice generator
• Mobile apps are essential
• You don't need AI, contracts, or proposals
• You're comfortable with form-based template filling

Choose Eonebill if:

• You want AI to generate invoices from plain English
