Our verdict on Billdu
Billdu is invoicing software for freelancers, contractors, and small businesses that need to create and send invoices from the web or mobile apps. It combines invoice creation, estimates, expense tracking, receipt scanning, online payment links, payment tracking, client management, and document exports. Multiple invoice currencies and languages make it suitable for businesses serving clients across markets, while team roles and access rights support small groups.
The paid plans are structured around client volume and collaboration. Lite costs $4.99 per month with annual billing and includes unlimited invoices, 10 clients, expense tracking, invoice status tracking, image attachments, and client signatures. Standard costs $9.99 per month with annual billing and adds unlimited invoices and estimates, 50 clients, up to 2 team members, payment reminders, and payment receipts. Premium costs $19.99 per month with annual billing and includes unlimited clients, up to 10 team members, recurring invoices, API access, and high-priority support. A 7-day trial provides an evaluation period, but there is no free plan.
Billdu fits users who want mobile access alongside web invoicing, with iOS and Android apps plus integrations for Stripe, PayPal, and Xero. Online payments, automatic reminders, recurring invoices, and multi-currency support cover common billing workflows without requiring a separate invoicing system. Lite is a practical entry point for solo operators with a small client base, while Standard suits small teams that need estimates and payment follow-up. Choose Premium when recurring billing, API access, or a larger client and team limit matters. Businesses needing a free ongoing plan or more than 10 clients without upgrading should consider another option.
