I have bought this module for my accounting. We do not have many transactions, thus it is a quarterly affair. However, the module saves us plenty of time. All our invoices and payments are imported just a few clicks away. Especially good for a small organization like us, it helps to reduce type-errors and import the information is a breeze.

Ridiculous, unnecessarily difficult installation and integration procedures that require you create a developer account at intuit. I've been in this industry for 25 years and the only other time I remember such a difficult installation process, it was another ModulesGarden product. I canceled before the 7-day trial ended and bought the WHMCS extension by MyWorks design instead.

Compare installation instructions between the two and you'll see what I mean.
ModulesGarden instructions: https://www.docs.modulesgarden.com/QuickBooks_Online_For_WHMCS#Installation
MyWorks instructions: https://docs.myworks.software/whmcs-quickbooks-sync-module/documentation/install-upgrade-instructions

I also noticed that MyWorks' app is listed on Intuit's Apps.com site but ModuleGarden's app is not listed on it. There must be a reason for that.

Lastly, MyWorks has 24/7 support in the USA. ModuleGarden support is available only during their business hours in Poland.

Had been using Modules Garden's QuickBooks for WHMCS since September 2015, since their 1st release. Though we had a bit of lag in understanding configuring QuickBooks dev login, ModulesGarden team assisted us at right time to get things setup.

Since then, we had been one of the early and happy clients of them. The module is made to the point, Sync clients, transactions and invoices. Also, the module has a very redundant code base which keeps us cool and out of worries. We hope to continue using this module for every.

Great work guys.

As Advanced Intuit Certified QuickBooks ProAdvisors, we had the pleasure of working with ModulesGarden on this outstanding Module. We used another product for several years, but it had many problems. This module far surpassed our expectations and MG continues to add new features! ModulesGarden is exceptional at keeping their modules up-to-date. We highly recommend MG! https://patriaco.com
