When I'm sending my invoices out, I send them many different ways. I accidentally saved a setting for future reference and now when I want to send a picture I can only send it on Facebook messenger. I've looked all over to for where I can undo this and I can't find a setting for this. Is there a place to change this that you could tell me about? And if not, you should add it to your app. It would be helpful. Update: I was able to fix the setting. It has since been a super helpful app to use!

UPDATE: Not much of a digital expert. ProBooks has been great for me. It works it is easy to set up, maintain and use. The few problems I have had over the past 3-4 years, were quickly answered and solved by an email to the company. Great work guys. I have used this app to set up billing on our business cell phones. It was an inexpensive easy to use alternative to much more expensive packages we considered.

Keep up the good work. a lot of my suggestions have been implemented. 👍🏼Appreciate that. Idk if it's just our company, but sometimes techs don't have the full name or correct name which in turn makes looking up customers nearly impossible. I wish there were a way to search for keywords or phrases and/or by (partial or full) address, ph#, etc. It would help extremely.

I just modified the app to cut the invoice number in the middle instead of at the end. This should help with your issue. Please drop me an email, we'll get all of your issues fixed. We just added new developers to our team.
