WHMCS Smarters Pvt. Ltd. Avis 

First of all the smarters team have all the patience in the world to support your every need once you get any of their services. They also build the best of APPLICATIONS for all devices from Mac, windows, android os, web, and everything current regarding your business needs. They have best employees in the business and they have support via Skype, telegram etc. The smarters team is simply for me the best in the business and they are the pioneers that built the bridge for us all to thrive. I'll always buy from them and I encourage anyone reading this that this is the most efficient and trusted source of business ideas and app development.
They also build apps and submit to Google play and ios stores and they pass.
They have good pricing for the work they do and they are the ORIGINAL. I rate them 5/5 I wish I can even rate them more higher.

So far it's good service, I have bought custom ott app from them. Good support team. Smarters Team's been always helpful when it's needed.
Highly Recommend !!

Have used smarters for 3 years+ and the support is incredible. These guys fix everything very quickly. From owner, developers to support workers, all of the team. Their work is exactly as I want it/ask for and the prices are absolutely brilliant. You won't find another development team like this anywhere else.

This company has been hacked, all data of customers are getting leaked due to bad security practices.

Smarters Scam Very Smart Way, Smarters will good support 6 - 8 months then smarters ask money for software update but website showing onetime fee and i confused here onetime fee meaning

⚠️WARNING ⚠️
SMARTERS ARE SCAMMERS SELL BROKEN VPN PANELS AND WONT FIX, ALSO THEY JUST BLOCK YOU IF YOU ASK FOR HELP

AVOID AT ALL COSTS
They take your money and run

We developed a custom WHMCS OnePagecheckout module from them. It worked all well when they developed for a specific WHMCS and PHP version. When we asked for some alterations/customizations they ask you for additional charges. Asking additional charge is not an issue but time to deliver is very poor. There is no timeline they mention and we need to followup. The product is not delivered on time and expected functionalities are not upto the mark. They don't try to fix the issue instead they put blame on other modules/gateways.

Well, I'm using the Smarters IPTV Module And custom Apps. They did great work on my custom apps and delivered great products to me. Works great!!

I have used their IPTV Billing Module. Its Working good. Smarters delivered great products & services.

Wow, stay far away form WHMCS Smarters. I ordered something, they didn't deliver it and they kept my money. Massive fraud going on, they're scamming people. I tried to message them multiple times but they do not respond. They took my money and ran and I am not happy.

Does not even deserve one star. Service is terrible. Replies to tickets take three days or more. After struggling for a month to sign up with them, I gave up. They do not even read tickets properly.

Do not use this company for anything, you will regret it.

I ordered for the wrong module, i ask for refund they wont refund me they are making me pay $133.

Do not use these thieves.
Take your money tell you excuses about anything and the product they supply they would not repair or correct...
BEWARE DO NOT USE....

Absolutely great products by whmcssmarters.
I was just trying xero Module for whmcs and it,s brilliant. It makes my work much easier. Now, I can sync thousand of invoices with a single click
I am sure there will be more products I would buy from them.
