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!

Hello there.
You can add your second business in the Settings. Our support team is keen to help you out and assist. Please make sure that you have the latest Billdu version installed. Have a great day!

Good app and presentation. But often very gitchy. The app always glitches when you go into a “service” for example- when you look up a “service” and then return to the previous screen, it glitches you into the landing page instead of the “previous page”. Very annoying. And now I cant print an invoice. There needs to be more checking for bugs before releasing an update.

Also, I’ve tried to suggest things that would turn this app into an app closer to the far more expensive apps out there and my suggestions are ignored. For example, how about making the customer Sign and adding a slot where you can add a sentence or short paragraph such as “by siging here I agree to pay upon completion of proposed work”. Great for small business owners in the trades like myself.

Nothing wrong with adding MORE and charging more $$ for this service. Not everyone is counting pennys, some of us dont mind paying extra for a better experience. Please stop keeping things so cheap (your prices) and sacrificing on quality and user experience.
