A Billdu alternative that doesn't punish you for signing a new client

Billdu undercuts almost every paid plan in this study. This page is about what buys that price: a cap on how many clients you can have, one that tightens exactly as your business grows.

BillingHub — 25 invoices USD 25.00 once, never expires
What Billdu costs Lite is $7.99, Standard $14.99 and Premium $27.99 a month — Lite is capped at 10 clients and Standard at 50; only Premium removes the client cap.
Clients 10 on Lite, 50 on Standard, unlimited on Premium
Multi-currency Yes — invoices in your chosen currency and one of 16 languages, per Billdu's own feature list

What Billdu is good at

Simple, uncluttered invoicing at the lowest entry price of any paid plan in this study — clean templates, expense tracking and estimates, without the accounting weight FreshBooks or QuickBooks carry. For a very small business planning to stay that size, the price is real, and this page isn't arguing otherwise.

Where it stops

  • The two cheaper plans are priced by how many clients you have, not by how many invoices you send.
  • That ceiling sits exactly where the business is trying to go: landing a new client is the goal, and on these plans it can also be what forces an upgrade.
  • Crossing it doesn't add a little to the bill for the one extra client — it moves the whole account to the next plan, priced around a client ceiling rather than around anything that changed in what you actually send.

When to choose Billdu over us

If your client list is small and staying that way, Billdu's entry plan is a genuinely inexpensive way to invoice. We price by the document you issue, not by how many clients are in your address book — a new client changes nothing about what the account costs.

Common questions

Does BillingHub charge more as my client list grows?
No. The price is set by the invoice you issue, not by how many clients are on the account — a new client changes nothing about what anything costs.
