Chaser vs Billdu
Billdu is a solid EU invoice tool. Chaser adds truly automated payment escalation.
Billdu covers invoicing, estimates, and expense tracking for EU businesses. It's a capable tool. But when invoices go overdue, Billdu's reminder system requires manual intervention — you still decide when to send, what to say, and whether to escalate. Chaser handles the entire sequence automatically.

Where Billdu falls short on payment automation
Billdu's core strength is clean invoice creation — it handles estimates, expenses, and EU VAT well. For businesses that primarily need to create and send invoices, it's a competent tool at a reasonable price.
The gap shows when invoices go overdue. Billdu's reminders are basic — they don't escalate in tone, they don't include payment links by default, and they require you to actively manage the follow-up process. For freelancers with 10+ active invoices, this quickly becomes a significant time burden.
Chaser's 4-stage escalation sequence is the core product, not a feature. Every aspect — timing, tone, payment links, stopping when paid — is optimised for getting overdue invoices paid faster.
