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!

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.

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

David is amazing. He is responsive, friendly, and an awesome asset to me as a non-developer manager of an OpenCart website. He customized one of his plugins for me, but not only that, he fixed several things that were wrong with my website in general that my previous developer either missed or didn't fix. He made the corrections with quality and speed. He also helped me in a tremendous way when my website crashed. He found the problem and helped me learn how to fix it. I am very impressed with David, his skills, and his products. I would recommend him with more than 5 stars if I could! Thank you David!

The extension is amazing and solves so many tracking problems we were having with this client.

But I have to say the support provided by David is in a league of its own! We had several problems getting set up (issues with our site, not the extension I hasten to add) but David responded quickly and got it sorted it out super fast. Always polite and (in our case) very patient with our numerous requests for help.

Wouldn't hesitate to recommend both the extension and David.

David was easy to work with and his extension Google Marketing Tools has made integrating Google and Opencart that much easier. Initial set-up had a few hiccups, but David was quick to assist in setting up both Google Tag Manager and modifying his extension. David made integrating his extension into our website a hassle free experience.

Anne / Bright Ideas
Marketing Coordinator
I cannot say enough good things about Devman. I am a programming rookie with a wholesale website to create and needed a LOT of help to get my it up and running properly (we have no programmer on staff). Due to my company's business model, I needed a fair amount of custom work done and "tweaks" to the opencart structure to be able to make it function the way it should and Devman was there for me every single step of the way. The costs were very reasonable, the service was excellent and very fast - even with being 7 time zones away, the works were always finished within a few hours of when they received the request. You are the first that I will reach out to for all future programming and extension needs! Thank you so much for all that you do!

Outstanding!
If I had to some up Devmans products, service and support in one word.
Whenever there have been any problems David has been very quick to answer, normally same day. Nothing is too much of a problem and he always goes that little bit further to help. It is a rare commodity to find such a high-quality, diligent developer.
We are already engaging with David for other ideas.

I'm so thankful to David for his Import / Export extension!

The Import module I bought helped me to replace my old custom Excel import system without even a bit of coding. The module is extremely powerful, so everything I might need is already included and all I had to do was to make proper settings. That's so amazing!

David is an excellent person to work with and I highly recommend his products to every e-commerce shop owners.

We are building eshop to sell electronics in central europe. Our supplier sent us just usuall XLS file with products. Without plugin made by devman it would take maybe two weeks to sync it with eshop. (or make from than useful XML or CVS). With plugin it took just one day. And support is great= fast response and will to help. Highly recommend.

We have found DEVMAN to be a very professional and a really nice and friendly company to work with. The bespoke development work they provided for us was quickly done and to an excellent standard. Equally their after sales support was exceptional. We would recommend their services and will be using DEVMAN in the future. A 5 star company.

Unbelievable customer service. Ran into a couple of issues when installing other extensions that caused an overwrite issue with the Discount Pro extension. Send a plea for technical support that was answered and issued resolved in hours, not days.

If you are looking to purchase ANY of the Devman extensions, do not hesitate! They work as promised and as mentioned, the customer support is excellent.

Hi,

I run an Indian Fitness Clothing Brand & I was in a mess with the plugin. I have a COD Plugin that works only with AJAX Checkouts (which wasn't working like I desired & hence I had to contact the support). David has been of a great help all throughout the integration process to make sure that the checkout as well as my customized module work together.

Big ups for the fantastic support offered by Devman.

Discounts PRO - Discounts products, categories, manufacturers
Create extension! Great support! Did exactly what I needed in the way of applying discounts. The repeat feature is critical. Example if you want to give a discount based on a certain number like 2 for $X , but not give a discount on a third item if added. But, if the customer buys 4, then the discount is repeated. Easy to set up, easy to maintain and change.
