I like the app, but it crashed after a few months, I guess it couldn’t store too much information. I tried to contact someone to help me with the issue, (there’s no telephone assistance available, although it says when you buy the app that there is. Credit card payment option doesn’t work either) they sent me an email suggesting I un-install the app and re-install it, I asked if I was going to loose my information by doing that. I was told no, as long as I log in into the same company with my password everything will be saved. So I did that, I managed to re-install the app I logged in and all, but none of my previous invoices or Customer’s info is there. I have to re enter all the info. Tried to contact them again to see if there’s a way to avoid having to re-enter all that info again into the app. And they just replied that if I want all my info, to access it from the Website, but I like the app, that why I bought it in the first place. Never got a reply back. In other words the customer service is terrible. Once you buy the app, you are on your own if something goes wrong. ☹️ so disappointed 😞

Hi Patty, you have created a new Billdu account instead of logging to the old one and our team is waiting for your response to our last e-mail. I am confident it can be sorted out quickly, our support team replies within few hours.

Used to run Invoice2Go but so buggy even after 5 years

Glad to find Billdu. Replaced Invoice2go and so glad I did. Works smoothly and well thought out. Can enter more information than necessary in my book but you don’t have to if you don’t want to. Running reports is a little cumbersome I need to set up multiple locations and can only get reports by one location at a time. Would like to run one report by locations I select. If someone can tell me how to do this would be appreciated. Also one more small thing, it would be nice to be able to tap and move invoice line items up or down instead of deleting and re entering the info. I’m still learning. But very happy and have been using it for 3 months now.
Customer service is usually 24 hours out. A live chat would also be helpful to answer quick questions.

Excellent but not sure if it fits our needs

We just sent our first Estimate through the app and have paid for the full year of service. But we have two business that we would like to put on it and it seems we’re unable to add our second business so we have to go back into settings and update our email address each time. As well we run a radon Mitigation company and handyman services. With the handyman services, more times than not the client provides all necessary materials and we only need to provide a labor estimate with a description of work to be completed. We worked around what was available but would like an option to place a labor only estimate that didn’t have Items on there as we won’t have any items to provide. But it does work well with our radon Mitigation company since we do the purchasing of the materials those do need to be listed. So it’s a 50/50. I gave 4 stars because it is an excellent app with so many options for our clients and us, but does not meet the necessities of our other company nor can it be added as another company. Thank you!
