  14. [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.

  19. [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
  20. [R12] Billdu 3/5 · US Review: After emails are sent it takes off the recipients name so I have no idea who I sent what to.
  21. [R67] Invoice Maker ▸ Estimate App 1/5 · US Charges you right away: Im super disappointed in this app how the dev team coded it to ensure everyone who downloads and signs up for the app has to pay immediate. The add said no payment to start and yet instantly they charged me almost $25. I recieved a polite email stating it wasn’t anything that they would charge re the amount. Asked if I’d like to send a screenshot. Hopefully the email was

  24. [R96] Invoice Maker ▸ Estimate App 1/5 · US Predatory Billing: I used this app one time upon downloading it, and was charged $10.79 every WEEK for months. I didn’t notice these transactions because I have other Apple charges for $9.99. Apple refuses to refund any of the charges, The app/support is of no assistance. If you sign up for this app WATCH YOUR BILLS
  25. [R108] Invoice Maker ▸ Estimate App 1/5 · US Why can’t I customize an ending date for the invoice?: This app is very user friendly and easy to use, but the BIG BUMMER is that I can’t customize the due date - we are limited to 3 or 4 choices, and that stinks when you want a 7, 3, or 17 day time period, but are forced to use a 10, 15, or 30 day window. We should be able to click any ending date on the calendar!
