The report card
Best for freelancers who need invoices and basic expense tracking
Billdu makes invoices and estimates and tracks expenses, in a browser and phone apps. But Lite is capped at 10 clients, reminders and estimates need the $9.99 plan, and the Xero link and the API are Premium only.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | $4.99 a month on yearly billing is inside the category's cheapest quarter, but Lite is capped at 10 clients. Estimates and reminders need Standard at $9.99. |
| Free plan and trial | C | A 7-day free trial with all features and no card. There is no free plan. |
| Features | C | Invoices, estimates, reminders, expenses and recurring invoices. A smaller job than accounting: invoicing and expense tracking, with the Xero link and API on the dearest plan. |
| Ease of use | C | No store rating on record, and you build your templates and client list first. |
| Platforms and integrations | B | Web plus iPhone, iPad and Android apps, with Xero and an API on Premium. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Billdu is for
- Fits if you invoice a few clients and want expenses in the same app
- Works for people who want to try it free for a week with no card
Who it is not for
- Tight if you have more than 10 clients on Lite, or more than 50 on Standard
- Skip it if you need estimates or payment reminders on the cheapest plan: both start on Standard
- Watch out: the Xero connection and the API are Premium only
- Watch out: the prices on the page are the average monthly price of a yearly plan, and monthly billing costs $7.99 and up
Good to know
Good for
- Freelancers who invoice from a phone
- Small businesses with a short client list
- Teams in Europe that need local e-invoicing formats
Worth knowing

- Estimates, quotes and payment reminders need Standard or higher.
- The Xero connection is listed only on Premium, and the API is Premium-only.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Billdu you could make: invoicing, quotes and estimates, expense tracking and reports. What surrounds it you could not. The 2 things listed below take a company, not a weekend.
It costs $59.88 a year.
What you could make
- Invoicing, quotes and estimates, expense tracking and reports: an app builder makes these well.
What you could not
- A real app for iOS and Android. Something home-made would be a web page.
- It plugs into other products, Xero among them, and has an API.
What this rests on. Billdu’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
