### 3/5 — It WAS great

*2025-02-11*

I’ve been using this app for years to make my invoices. Got a new phone and redownloaded it. Only to lose all my data, had to restart from scratch and now after 2 invoices I have to pay. What’s that about?

### 3/5 — Almost perfect

*2024-09-30*

This app would be perfect if it didn’t limit you to 30 Character descriptions on items. 

Also if my devices could sync so I can see all invoices from my iPad and iPhone.

### 5/5 — Nice and easy

*2024-08-14, version 1.4.1*

Easy to use

### 3/5 — Information does not transfer between devices

*2024-04-07*

I’ve had to redo my invoices from my iPad to my phone. Totally separate

### 1/5 — Didn’t work

*2024-03-12*

I paid for it. Everything seemed to work until
I marked the customer as paid.  It didn’t change anything. It said paid on my end but I couldn’t send the customer a receipt saying paid.  When I tried sending the paid one.  It sent them another invoice saying they owed money. 
Logo is also very small

App is easy to use but does not work
