Too many bugs to be considered production ready. Further, non-existent support when you need help.

Too many bugs. Communication is not good. Also, they didn't deliver the product as promise date.

I asked for a refund within 2 days of purchasing the product and Amanpreet Singh informed me that he would like to improve the product and told me to wait but told me I would be refunded if I did not like the product after he changed it. I agreed and waited. After about 3 weeks of not hearing back from anyone. I stated I would like my money back and was refused. Here is the conversation between myself and Amanpreet Singh:

Some of the original conversation was deleted by whmcssmarter's staff but enough is there to state my case. Hopefully other buyers will read this, no one should do business with a person or company that behaves in such a way.

This clearly states a 7 day refund, and I was lied to and told to wait until the 7 days expired to be refused a refund.

Also, this form requires complete customization of an external page on your WHMCS install, also not recommended because it goes outside your WHMCS theme. The default design is also very poor.

Hi Carlos,
Could you please contact us via email and tell us what issues/bugs are you getting?

That doesn't make any sense to write " To bugs"?

Make sure you are using or used our latest Version

My entire client experience was horrible, I am leaving a 3 star review instead of 1 simply because the end product finally works as expected after 3 months! I purchased their one page checkout and added some customization options and expected this to be finished in a couple of weeks. Man was I wrong! - There are literally way too many issues to list them all here, however the entire project was filled with: complete disregard at first, lack of communication, simple 1 sentence responses, miscommunication from their developers who cannot communicate properly in English, and did I mentioned BUGS, BUGS AND MORE BUGS! - After 2 months of all these issues, I spent an additional month just helping them find and crush bugs. Maybe their products would work fine but I would definitely not recommend them for any custom WHMCS work at all.

Owner Update: I paid extra for cart customizations. My css changes on cart customizations are not extra work. Anyhow that is just one of many of issues your company has. Maybe you should spend as much time you do on responding reviews to ensuring client fulfillment is done properly, this way you wouldn't have as many bad reviews as you do ;)

Client Sign up date : 28 October 2017 - How can you say that it's 8 monhts. why are you telling a lie on public place?

Let me share the TRUE Story to App:

He keeps discussing with us how it look like till 9 November 2017.

we have started 10 Nov 2017 and we submitted after changes according to his feedback on 15 November.

( that’s good thing we are happy to make changes according to client’s feedback)

then he asked again for few changes on 15 November 2017 and we have done and submitted again on 21 Nov 2017.

Then he asked for changes again 22 November and we requested for extra payment because we are NOT provider free services again again . this team he had to pay for it.

then he refused to pay us but after sometimes he agreed on it and paid . we started making the changes again.

and submitted to him again with responsive design again.

then we were waiting for his response. he has not responded after getting the job done.

then he got a license issue and got it fixed quickly

Then he again came to us on 27 December 2017 and asked for more changes. but he was not willing to pay this time but we did it.

then we found minor things that we have fixed during 4 jan to 11 Jan 2018.

then he didn’t respond till 20 Jan 2018.

Then we found there was problem with his WHMCS but our developer has fixed without any COST.

then 13 Feb 2018 he messaged us , Everything is Good.

Changes what we have done for him that were

- JS related changes in the Payment method according to latest WHMCS 7.4 and header and Footer.
- New Popup added to client’s signup

- other changes according to his suggestion.

What else you want my dear client?

Hi everyone! Not sure about your experience with WHMCS Smarters but ours was really great. They have very good products ( the one page order form is stellar ) and more than this they accepted to do some extra work for us to modify the order page as we wanted. The price is AWESOME! Just try to talk with a dev company to see how much they will ask you for this kind of project.

Our poject was done in a few weeks because we had some custom things that we modified and it took some time for dev but in the end everything was as expected. I really recommend these guys. I want to give a BIG THANKS to Harmandeep - he was the PRO dev that was able to help us with most of our issues.

Not good as price...

Hi Mahmudul,

Did you buy this module and used it ever?

Also, I have many clients using this solution happily.

About Price: As I mentioned in the description, first we have to design a mockup according to the website then we integrate it according to main website design. it's not a pre-built solution.

No one can judge the module without using it
