Pronto Invoice vs Invoice Simple

We’re Pronto Invoice, so naturally we think our product is the better choice. But we also know different businesses have different needs.

Invoice Simple is one of the most popular invoicing apps on the market, with over 500,000 users and a strong reputation for straightforward invoicing. Pronto Invoice is a newer entrant built around AI-powered invoice creation and a mobile-first experience designed for field service professionals, freelancers, and small business owners.

This comparison breaks down exactly where Pronto Invoice and Invoice Simple differ — pricing, features, mobile experience, AI capabilities, and more — so you can make the right call for your business.

Pricing Comparison

Both Pronto Invoice and Invoice Simple use tiered pricing, but the structures differ significantly.

Pronto Invoice Pricing

Invoice Simple Pricing

What the Numbers Mean

If you send fewer than 10 invoices/month: Pronto Invoice’s Free plan costs $0 vs. Invoice Simple’s Essentials at $4.99/month. That’s $60/year saved on Pronto Invoice.

If you need unlimited invoices: Pronto Invoice Growth at $12/month vs. Invoice Simple Premium at $19.99/month. You save $96/year with Pronto Invoice — and get recurring invoices, QuickBooks sync, and AI creation that Invoice Simple doesn’t offer at any tier.

Payment processing: Pronto Invoice charges zero markup on payments. You connect your own Stripe or PayPal account and keep whatever rate you’ve negotiated. Invoice Simple charges 2.9% + $0.30 per transaction through their payments platform. On $5,000/month in processed payments, that’s $150/month in fees with Invoice Simple vs. ~2.9% through your own Stripe rate (roughly $145/mo at standard Stripe pricing). The difference grows as your volume increases and as you negotiate lower Stripe rates.

Where Pronto Invoice Wins

AI-Powered Invoice Creation

This is the single biggest differentiator. Pronto Invoice’s Smart AI lets you create invoices by typing (or dictating) what you need in plain language:

• “Invoice John Smith $500 for plumbing repair”
• “Bill ABC Corp for 3 hours electrical work at $85/hour”
• “New invoice for Sarah Chen, website design, $3,000”

The AI handles client matching (fuzzy search finds “John” from “John Smith” in your contacts), item suggestions from your catalog, tax calculations, and document assembly. Repeat clients with saved items take under 15 seconds.

Invoice Simple uses traditional form-based creation. You navigate through fields, search for clients, manually add items, and configure settings step by step. It works — but it’s significantly slower, especially on a phone.

For a contractor finishing a job and wanting to invoice before leaving the job site, the difference between 15 seconds (AI) and 90+ seconds (forms) matters every single day.

True Offline-First Mobile Experience

Both apps have mobile apps. But Pronto Invoice was built mobile-first — the phone app isn’t a companion to a desktop product. It IS the product.

What that means in practice:

• Full offline support. Create invoices, add clients, manage items, and preview PDFs with no internet connection. Everything syncs when you reconnect. Invoice Simple’s offline capabilities are limited.
• One-handed operation. Every critical action is reachable with your thumb. Navigation tabs at the bottom, primary buttons in the lower third of the screen. Important when you’re holding a tool or clipboard in your other hand.
• Sub-2-second launch. Fully native iOS (SwiftUI) and Android (Jetpack Compose) apps. Not web wrappers. Fast, fluid, battery-efficient.
• Voice input. Tap the microphone and dictate line items, notes, or project names. Useful with dirty or gloved hands.
• Camera integration. Photograph receipts, attach job site photos (up to 4 per invoice), and document completed work.

Invoice Simple also has well-rated mobile apps (4.8 stars across 284K reviews — a genuinely impressive achievement). But user reviews consistently mention the apps are better suited for simple invoicing rather than complex field work.

Recurring Invoices

If you have retainer clients, maintenance contracts, or subscription billing, Pronto Invoice handles this automatically on the Growth plan ($12/month):

• Schedule invoices weekly, bi-weekly, monthly, quarterly, semi-annually, or annually
• Choose auto-send (hands-free) or draft mode (review before sending)
• Set end conditions: never, after X cycles, or on a specific date
• Pause and resume without losing your configuration
• View complete generation history per recurring template

Invoice Simple does not currently offer recurring invoices. For businesses with regular billing cycles, this means recreating the same invoice manually each period — a time cost that compounds with every recurring client.

An HVAC technician with 25 monthly maintenance clients saves 5+ hours per month by automating recurring invoices.

Zero Payment Processing Markup

Pronto Invoice never takes a cut of your payments. Connect your own Stripe or PayPal account and pay whatever rate you’ve negotiated directly with them. As your volume grows or you negotiate better rates, those savings are entirely yours.

Invoice Simple processes payments through their own platform at 2.9% + $0.30 per transaction. That’s standard for the industry, but it means Invoice Simple earns revenue from every payment your clients make. With Pronto Invoice, 100% of the processing relationship is between you and your payment provider.

For a business processing $10,000/month: Invoice Simple’s fees cost approximately $320/month. With your own Stripe account at the standard 2.9% + $0.30, you’d pay roughly the same — but you retain the option to negotiate volume discounts directly with Stripe, which Invoice Simple’s platform doesn’t offer.

Where Invoice Simple Might Be Better

We believe in honest comparisons. Here’s where Invoice Simple has advantages:

Established Track Record and Review Volume

Invoice Simple has 284,000+ app store reviews and 500,000+ users. That’s a massive, proven user base. Pronto Invoice is newer to the market. If you prioritize a tool with years of community feedback and a long operational history, Invoice Simple has the track record.

Client Signatures on Estimates

Invoice Simple’s Premium plan includes the ability to request client signatures on estimates — directly on the client’s phone. This is useful for contractors who need client approval documented before starting work. Pronto Invoice does not currently offer in-app client signatures (this is on our roadmap).

Simpler Feature Set

Some users genuinely want fewer features, not more. Invoice Simple deliberately keeps its feature set focused: invoices, estimates, payments, basic expense tracking. If you don’t need AI, recurring invoices, QuickBooks integration, or multi-user support, Invoice Simple’s simpler approach may feel less overwhelming.

What Real Users Say

Pronto Invoice Users

“I can invoice customers before I leave their driveway. The AI just gets it — I say what the job was and it builds the invoice. Game changer for a one-man plumbing operation.” — Mike R., Plumbing Contractor

“Finally an invoicing app that works without cell service. Half my jobs are in basements or rural properties. I create the invoice on-site and it sends when I get back to my truck.” — Dave T., Electrician

“Switched from another app because I was tired of tapping through 8 screens to create a simple invoice. The 5-step workflow is exactly what it should be.” — Sarah K., Freelance Designer

What Invoice Simple Users Say (App Store Reviews)

“Simple and easy to use. Does what it says. My only complaint is the price has gone up.” — App Store review

“Works great for basic invoicing. Would love to see recurring invoice support added.” — App Store review

“Good app but limited on the lower tiers. 3 invoices per month on Essentials is not enough for most businesses.” — Google Play review
