What Is Invoice Maker?

Invoice Maker is an online invoice generation tool created by Saldo Apps in 2019. It targets freelancers, contractors, and small businesses in the US, UK, Canada, and Australia. Its core value proposition is simplicity: choose a template, fill in your details, download or send.

Key features of Invoice Maker:

• 500+ invoice and estimate templates

Pricing Comparison

| Plan | Invoice Maker | Eonebill |

|------|-------------|----------|

| Free | 1 invoice/month | 3 clients, 30 docs/mo |

| Pro | $9.99/month unlimited | $19/month unlimited + 50 e-signatures |

| Business | — | $69/month unlimited + white-label + API |

Eonebill's free plan gives you far more value than Invoice Maker's free tier — 3 clients and 30 AI docs/mo vs just 1 invoice/month.

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

| Document | Invoice Maker | Eonebill |

|----------|--------------|----------|

| Invoice | ✅ | ✅ AI-generated |

| Contract | ❌ | ✅ AI-generated |

| Proposal | ❌ | ✅ AI-generated |

| Estimate / Quote | ✅ | ✅ |

| Receipt | ❌ | ✅ |

| Expense | ❌ | ✅ |

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
• You need contracts, proposals, estimates, receipts, and expense tracking
• You want 5 free AI invoices per month (vs Invoice Maker's 1)
• You want a platform that grows with your freelance business

For US freelancers serious about running an efficient business, Eonebill's AI-first approach saves more time and covers more document types than any template library can — regardless of how many templates it has.
