About this app

Create professional invoices, estimates and purchase orders in seconds with the Billdu invoice generator and estimate app, an easy invoice maker built for UK sole traders, contractors and small businesses.

Can't do decimals for quantities, for example .5 hours. Can't send via email. I have to download the pdf and email it via my email client. Clicking on "unpaid" invoices doesn't show any late invoices. Last I checked late invoices are considered unpaid. I really regret paying for a whole year upfront. Save your money people, there are much better options with a much easier to navigate UI.

Used billdu now for 2 years, They update it every 6 months only for the app to work worse, support is 0 help as well. We told them you can't send invoices via email because they show up as "deleted", they said "nobody has reported this problem" and then offered no help, even after the second time reporting the same issue. Meanwhile they have more than doubled the price for their unlimited customers. We would rate them lower if we could. If you want to keep your clients, do NOT use this app.

So far we are pretty impressed with app. Great price User friendly. My only down side is on the invoices when a customer has given a deposit I reflect it on the invoice and the total price still shows original amount at bottom right. We have had customers get confused. Where total is it should have another line with new total automatically adjusted not just listed. As we all know customers just look at numbers they don't calculate the difference. The invoice should do that automatically.

Hi there, thanks for the review. The total price doesn't change of course but the Total Due changes :) The due amount changes with every payment added. For more information take a look to our guide or contact our support and we'll navigate you. Have a nice day.
