Used for about 4 years now, very good and simple to use. Something I'd like to request is a subject or text line visible on the list of documents page, which will allow me to name an invoice instead of just seeing the client name. I often have multiple invoices to the same client - being able to single out documents on the doc page, by titling them with property address (in my case), would make things a little easier. If this is already a feature, could you enlighten me..😃

I have used this app for all my invoicing, for 3 years now. I've given it only 3 stars because, it's just lacking in everything it does. For example, this year, the email that's pre typed, is one long sentence. Invoices numbers, have to be manual entered. Summaries dont calculate. It's hard to "confirm payment" I also think, £22 for a year is overpriced, for an app that's not 5*.

Hi Keith, thank you for a review, maybe you have some old Billdu version :) Invoice numbers are added automatically, payments are added with two clicks and the dashboard calculates your invoices&expenses and displays summaries and taxes. I"m not sure what you mean by pre-typed email, in case of any issues or questions contact support@billdu.com

It's been a frustrating experience. I've been trying to resolve an issue with the link notification not working for over three months now. They’re quick to take payments, but when I stopped paying, they deleted all my contact details and customer information—despite being with them for over three years. The way they've handled this is absolutely unacceptable.
