  4. [R22] Billdu 1/5 · US Save your money: I was a subscriber since 2019 and loved it for the first couple of years, but around 2025 things started going downhill. Like any company, they got super greedy, prices jumped to nearly $30 a month, features that used to be included were pulled out and turned into separate paid apps, and the value just wasn’t there anymore.

  16. [R18] Billdu 3/5 · US Glitches: Great app. I get everything done from my phone. Saves me time and money. I’ve had issues with client names being deleted while making changes to their quote. It seems very difficult to find any way to contact or talk to someone about my issues. I am able to manually go in and add their name every time I make a change so no data loss but it is frustrating since I have so much info in this
  17. [R19] Billdu 1/5 · US No support: I can’t contact support, I click on support and it does nothing. Every time I send an estimate or an invoice it deletes the contact information from the document and then I need to edit the document to add the contact information back. This has been going on for months and none of the updates have done anything to even give me the ability to contact support about this. Fix it and I wil
  18. [R41] Billdu 2/5 · US This app sucks: If you have an issue an AI bot is there to help you and then disconnect from the conversation without warning. I paid for a yearly subscription only to find out I can only do invoices not estimates but for some extra cash I could. Who built this inconveniently confusing app. My membership wasn’t over until may 14 2026 but some how it’s expired 2 months early. Give me my money back
  19. [R25] Billdu 1/5 · US Not so great anymore: App is good in getting all your information together for invoice, but my clients names ALWAYS disappear anytime I have to make an edit, it’s very very frustrating and I can’t seem to fix the issue even with updates

  22. [R75] Square Invoices 3/5 · US Transaction Fees: I love using square but honestly it’s missing 1 key thing: lower transaction fees. You’re charged when receiving money AND when you transfer it to a bank account. It seems very greedy
  23. [R94] Square Invoices 5/5 · US Over charge on instant deposits: The price is to expensive for instance deposits I will be searching for others app
  24. [R63] Square Invoices 3/5 · US Can’t delete invoices: Once you make an invoice it’s impossible to delete so now I have a random $5900 invoice that I don’t want. So now my outstanding bill is off by $5900.
