Pronto Invoice vs Billdu

We’re Pronto Invoice, so we obviously have a preference. But we also know that different businesses need different tools, and we want to give you the information to choose well.

Billdu is a European-founded invoicing app with a strong mobile presence, multi-language support (12 languages), and features like client signatures, OCR receipt scanning, and Apple Watch support. It’s particularly popular with small businesses in Europe and users who need multilingual invoicing.

Pronto Invoice is built around AI-powered invoice creation and a mobile-first, offline-capable experience designed for contractors, freelancers, and small business owners who need speed in the field. We focus on getting invoices created and sent in under 15 seconds.

This comparison breaks down exactly where each platform excels — pricing, features, mobile experience, and more — so you can make the right call.

Pricing Comparison

Pronto Invoice Pricing

Billdu Pricing

What the Numbers Mean

If you send fewer than 10 invoices/month: Pronto Invoice’s Free plan costs $0 vs. Billdu’s cheapest option at $4.99/month (annual) or $7.99/month (monthly). That’s $60-$96/year saved.

Watch the client limits. Billdu Lite caps you at 50 clients. Standard allows 250. Only Premium ($27.99/month) gives you unlimited clients. Pronto Invoice Growth ($12/month) includes unlimited invoices AND unlimited clients — $16/month cheaper than Billdu Premium.

Recurring invoices: Pronto Invoice includes recurring invoices on Growth ($12/month). Billdu restricts them to Premium ($27.99/month). That’s $192/year more for the same feature.

Payment processing: Pronto Invoice charges zero markup on payments. You connect your own Stripe or PayPal account. Billdu processes payments through Stripe integration with standard Stripe fees.

Where Pronto Invoice Wins

AI-Powered Invoice Creation

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, item suggestions from your catalog, tax calculations, and document assembly. Repeat clients with saved items take under 15 seconds.

Billdu uses traditional form-based creation. You navigate through fields, select clients from a list, manually add line items, and configure settings. It works, but it’s significantly slower — especially in the field on a phone.

True Offline-First Architecture

Pronto Invoice was built with offline-first as a core design principle, not an afterthought.

• Full offline support. Create invoices, add clients, manage items, and preview PDFs with no internet connection. Everything syncs when you reconnect.
• One-handed operation. Navigation and primary actions designed for thumb reach.
• Sub-2-second launch. Fully native iOS (SwiftUI) and Android (Jetpack Compose) apps. Not web wrappers.
• Voice input. Dictate invoices in the field with dirty or gloved hands.

Billdu has mobile apps with some offline capability, but it’s not built on an offline-first architecture. In areas with poor connectivity — basements, rural job sites, construction zones — this difference becomes critical.

QuickBooks Integration

Pronto Invoice offers native QuickBooks Online sync on the Growth plan ($12/month). Invoices, clients, items, and payment statuses stay synchronized in real time. This eliminates double-entry for businesses that rely on QuickBooks for accounting.

Billdu does not currently offer QuickBooks integration at any tier. If QuickBooks is part of your workflow, this is a significant gap.

SMS Invoice Delivery

Pronto Invoice lets you send invoices via text message (Growth plan, $12/month). For contractors and field service pros, SMS often gets faster responses than email. Billdu does not currently offer SMS invoice delivery.

Recurring Invoices at a Lower Price

Pronto Invoice includes recurring invoices on Growth ($12/month). Schedule weekly, bi-weekly, monthly, quarterly, or annual invoicing with auto-send or draft mode. Billdu restricts recurring invoices to its Premium plan ($27.99/month or $19.99/month annual).

Where Billdu Might Be Better

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

Multi-Language Support

Billdu supports 12 languages. If you invoice clients in multiple languages or operate in non-English-speaking markets, Billdu’s multilingual support is a genuine advantage. Pronto Invoice currently supports English only.

Client Signatures

Billdu includes digital client signatures on all plans. Clients can sign estimates, invoices, and documents directly on their device. This is valuable for contractors who need signed approval before starting work. Pronto Invoice does not currently offer client signatures (this is on our roadmap).

Apple Watch Support

Billdu offers an Apple Watch app for quick access to invoice status and notifications. Pronto Invoice does not currently offer Apple Watch support.

Broader Device Support

Billdu has dedicated apps for iPhone, iPad, Apple Watch, and Android — with interfaces optimized for each screen size. Pronto Invoice focuses on iPhone and Android phone experiences.

Unlimited Invoices on the Lowest Paid Plan

Billdu Lite ($7.99/month or $4.99/month annual) includes unlimited invoices. Pronto Invoice requires the Growth plan ($12/month) for unlimited invoices. If you need unlimited invoices at the lowest possible price and don’t need AI, QuickBooks sync, or SMS delivery, Billdu Lite is cheaper.
