Who should pick which?
Pick InvoiceQuickly when…
Pick InvoiceQuickly for AI-driven invoice creation, AP automation, and US/EU/global tax compliance baked in. Billdu is solid mobile invoicing software with appointment booking, expense tracking, and a clean iOS/Android experience, but it doesn't have AI generation or AP processing.
Pick Billdu when…
Pick Billdu if mobile invoicing + appointment booking + customer management in one tool fits your workflow — service-based small businesses (cleaners, beauty professionals, mobile mechanics, freelance trades) are the sweet spot. Plans run $4.99-$19.99/mo and bundle features that would otherwise require multiple tools.
Three worked scenarios
Real situations and the recommendation we'd actually give.
Books, services, invoices same client weekly.
→ Billdu — bundled booking + invoicing wins here.
Doesn't need recurring appointments; needs branded invoices.
→ InvoiceQuickly — AI + photography template + better visual brand.
Outgrowing solo invoicing tools, needs vendor bill processing too.
→ InvoiceQuickly Business ($249/mo) — Billdu doesn't process AP, and the team workflow features are stronger in dedicated platforms.
Switching from Billdu
Billdu exports clients and invoice records as CSV. Appointment data doesn't transfer (InvoiceQuickly doesn't bundle scheduling). Most teams keep Billdu for booking/scheduling and add InvoiceQuickly only for higher-value invoicing or AP processing.
The Verdict
Choose InvoiceQuickly if you want AI-powered invoicing with a free tier (5 invoices, 5 clients), 200+ templates, and advanced AP automation. Choose Billdu if you need purchase orders, QR code payments, and camera-based receipt scanning in a mobile-first billing app, particularly for EU-based businesses.
