Invoice Simple Reviews 

I keep getting 0 invoices left for both my accounts. I am paying for unlimited in both and within the last few days have been getting this issue when I have never had an issue. Each time you guys want me to delete and install the app again and if I have to do it again i will cancel both of my subscriptions and write a negative review

I've been using Invoice Simple for years. The app and site make it super easy to generate new invoices and I love that I can start one on the app and continue building out the invoice on the website, so no matter where I'm at, I can always adjust on the fly.

Exceeding Expectations

I had an amazing experience resolving invoicing issues . Rose helped resolve the arising issues within 3 minutes . Understood my requirements and acted swiftly to resolve.

I highly recommend Invoice Simple for invoicing and booking needs

Had a problem creating new invoice due to billing issues. Tried using the chatbox to connect with customer service. Alvin was very helpful and patient. helped me solve the issue!

They were very prompt on getting the issue resolved, even though there has been many issues recently

Invoice Simple are always there so quick with help. Problems are always solved very quickly, not that I've had many in all the years I have been using Invoice Simple.
Thank you for always being there.

Great support and quickly restored my app.

I took out a premium subscription with Invoice Simple on 26-02-2026.
Subscription costs €204.99.
The costs were initially €55 per year.
Every year, the costs increase significantly.
You would expect top-notch service for that.

But unfortunately, that is not the case.
This is the third time in 3 months that the app isn't working again.
I am being asked to take out a subscription worth €204.99 again.
My subscription is not even 2 months old.

Contacted the technical team at Invoice Simple.
Their advice was to log out of the app and log back in.

And to restore the purchase.

That doesn't work at all.
Their solution: they are not providing any further updates.
What does it come down to?

Paid €204.99 for two months of misery.

And now I can't do anything at all with the app.
Which is a problem because I have to create and send invoices every day. This is costing me clients and causing me to get into trouble with my clients.

Customer service is brilliant, helped fast with the issues I’ve had. 10/10 from me.

Easy and simple to use

Invoice Simple is an excellent, affordable quotation and invoicing programme, very helpful support, great product, highly recommended.

About 11 o’clock at night I had a question regarding the invoice set up within minutes I had a real life person who gave me straightforward step-by-step directions to get my issues straightened out.

Absolutely impossible to get support from this company.

I’ve been a paying customer for years, and suddenly my account has been restricted without any proper explanation. Despite payments still being taken, I can no longer send invoices or even access my own data properly.

To make things worse, all I receive are automated responses (in Dutch), with no real customer support or resolution. I’ve tried multiple times to get in touch, but it’s like speaking into a void.

They’ve effectively locked me out of my own invoices while continuing to charge me — which is completely unacceptable for a service that businesses rely on.

If you’re considering using this platform, think twice. When things go wrong, there appears to be no real supportonly A.I that speak in a different language , no accountability, and no urgency to fix serious issues.

Extremely disappointing experience.

Always a quick response and very helpful. I especially like that when AI is unable to help a human always steps in on request! 😀 Highly recommend!

Absolutely fantastic , couldn’t have asked for a better person to represent

Shawn was Great! Very helpful and quick responses. Great support make me feel better spending the 20.00 a month

Jeralyn was extremely helpful. I appreciated the follow up and the suggestion. Great customer service experience

Super easy app to use and set up.
Will recommend to anyone.
Great customer service!

Where do I start.... No one will take ownership of the issue, all I keep getting is go speak with google support ... How is there not a team that liaises with Google support, I've been charged for 3 months consecutively on two different plans/subscriptions one being plus and the other one being premium. Both invoice simple and Google support say a a refund is valid as they can both clearly see that have been charged three months but no one can do a refund as it falls out outside of Google's supports policies and invoice simple don't do refunds at all apparently..... I've been a customer with invoice simple for the last four and a half years and I'm disgusted in the way that I've been treated as a customer.

I have used your system with great success. A few days ago my payments were not going through but the support team helped me greatly and solved my problem very fast. They communicated with me in such a simple way that my frequent "nerves" were littled and had everything flowing now. Thanks IS TEAM.
