What our customers say about us
Great support! It's the fastest OpenCart support I have ever received! TWICE. LIVE SUPPORT! They logged in our system, diagnosed it, fixed it, and kept me updated while doing so. Would strongly recommend. Looking forward to creating more efficient ad campaigns. Thanks, guys.
I'm totally satisfied with a) the communication to Devman...all answers came quick and were very helpful b) the understanding of our issue and fixing it I worked with a lot (!) of developers in the last 8-10 years. And I can tell you, that it's really hard to find a such professional developer, as I found here. Easy five star-voting without any doubts!

David / Devman is a great asset to the OpenCart community. As a customer for the Google Marketing Tools and Import/Export extensions, I've found both his products and customer service to be gold star quality. He is always professional, courteous, and extremely helpful, and very prompt to address any issues that may arise (typically occurring at my end). If I could rate his products and service a 6, I would do so without hesitation!
David is a pleasure to work with. He is deeply knowledgeable about his products, supportive and very reliable for rapid help when the need arises. His Opencart plugin is one of the best and most comprehensive we've found, and we look forward to seeing his products reach more shopping carts for our integration with Google Shopping campaigns. David is highly recommended!
The support I received was simply outstanding - form a fast response time - to just helping me resolve my issue - which was actually down to myself importing data incorrectly! Devman went above & beyond to help me out & ensure I understood what to do. The import/export module is simply brilliant & the level of functionality is superb - I cannot recommend it enough if you are pulling data in & out of your opencart store & the fact it is also backed up by such good support is simply brilliant I have bought quite a few of Devmans extensions and with any issue he always goes out his way to help & resolved and is always really friendly (even when the fault is the users!)

I purchased OPTIONS COMBINATIONS extension. It works as was promised in the description - no bugs noticed. But the review is mostly about custom development for this module. David helped me to adjust extension to subtract stock from another products as donors within different depended conditions in a single product. I "changerequested" a few times, to try possible variations. It took time and nerves from me, but not from David. He was highly professional and reacted each time with maximum proficiency. Definitely high skilled developer, as for me. I'm completely satisfied with our project. I recommend David as a developer, Devmanextentions as a company for your needs.

We requested some custom work for our website and could not be happier, the Devman team were super responsive and very efficient in implementing all the requests. This is the best support we have ever experienced. Will definitely be using Devman Extensions and thier team again. Thank you.
Fantastic quality extensions and awesome support. If i could i would rate them with 10 stars. Please keep up the good job. Extension: Excellent! Support: more than excellent! Responce time: Great! Cheers!
Google Marketing Tools has helped to elevate our business to the next level. It was a little hard to setup everything and sync to the google tools to get everything tracking but Devman is quick assist and makes it much simpler. I also love the constant updates to the module that keeps it running perfectly.
Since 2015 I work with the Opencart Plugin Google Marketing Tools from Devman Extensions. His work is always complete and up to date. With this plugin you have all the marketing requirements in 1. All important functions for Adwords, Google Ads, Facebook, Twitter, Criteo, Google Merchant Center and Hotjar are available. The plugin is regularly updated to the latest standards. Every fix was within a few hours. Not once but every time. In addition, he takes every adjustment into the next update so that you do not run into the same error again. Very reliable and easy to set up. Keep up the good work!
David is one the most talented people I have had the pleasure to meet and work with. His knowledge in programming language is out of this world. Anything I throw his way he fixes like it was no big deal. Knowing how to do some programming, his work is very clean, very detailed, and noted where the changes are made. I couldn't recommend anyone else but him when it comes to great work, very responsive and knowledgeable in the field he dearly loves. I've been doing this a long time, and I thank God i met this young man to save me at the last minute when something happens.
Очень быстрая и доброжелательная поддержка. Все вопросы решаются быстро и максимально эффективно. Сам модуль пожалуй лучший для Экспорта-Импорта для OpenCart 3. Постоянные обновления очень радуют. Разработчик прислушивается к пожеланиям пользователей. Появилась русская локализация. Очень рекомендую. Своих денег стоит однозначно Very fast and friendly support. All issues are resolved quickly and as efficiently as possible. The module itself is probably the best for Export-Import for OpenCart 3. Constant updates are very encouraging. The developer listens to the wishes of users. Appeared Russian localization. Highly recommend. His money is definitely

David is a fantastic developer - I have used several of his modules across various websites for different clients and they always do exactly what they say they will do - they are easy to install & come with clear instructions. Any time I have had to get in touch the support offered has been second to none - really fast response time, really helpful and a pleasure to deal with. I highly recommend David and his modules & web services.

I am using The google markting tools and the Quick n Easy Chekout Extensions, and it is working very good. My developer did not made a great job at my checkout page, but David (the real ID to Devman) did, and helped me too much to solve my issues. Theese extensions are really relevant to our e-commerce by now. THANK YOU AGAIN
The Import / Export Pro extension is a must for everybody, it is a fantastic time saving extension for Opencart, I imported 2,000 categories in a few seconds. The mapping of the cvs sheet makes it easy to construct and import into Openccart. I had to contact the developer about the module, not because there was a problem with but I had missed a step a step if refreshing the cache for the categories to show in admin after import. The response was fast and dealt within an hour. I strongly recommend this product.
