Beware - price rises constantly. This used to be a great cost effective system for generating quotes and invoices and I recommended it to multiple clients. Well I won't be any more as the costs have almost doubled since my first client signed up. They say it is due to 'new features' but we don't need any of these, we want it to continue working as before. I could understand maybe a £1 rise every few years but it's just not good value any more.

Already complained about this, but still nothing has been done... switch off auto save on the items!!! It saves every little detail you insert into invoices and estimates!! I dont want an invoice from last year saved as a quick access! Also let me delete multiple items at once instead of having to click into every item and manually delete it!!. I was told this feature could be turned off on the app which is a lie!

Didn't realise I had to pay after making 3 invoices. When prompted to subscribe, I tried to. I tried every means possible but they all came back with an error for no reason whatsoever. Follow up 1 year later: the issues never got resolved. Their reply to my review is to look like they're responsive but they're not. The issues never got resolved. Didn't use app again, told account was closed. They've now taken the annual payment out my Google account as a new subscription!!!!

Hi Katelyn, sorry about this! Unfortunately all purchases are required to go through Google Play, I'm sorry to hear Google Play was unable to take your payment. You can contact us for support 24x7 within the app, we usually respond within 5 minutes, but, it can take 1-2 hours if we are busy. Thanks, Alex alex@getinvoicesimple.com
