I have tried most of the checkout solution for opencart, but these 3 are by far the best i have installed ever, they work together like the perfect symphony, fantastic layout, look and feel, extreemly well written, loads of options in admin and they never ever generates errors, and i am scared shittless when installing new nodules having already over 80 modules installed in my shops, -that after years are finaly dancing in harmony. these 3 modules complete my shops. Support, well Xtensions is just there 24/7. A must for every opencart shops!

Really great modules, support and employees.Knowing Xtensions now more then one year. Helpfully and friendly guy. Support is perfect. Answering really fast. We are using Xtensions-Best Checkout and also Xtensions-Abandoned Cart and Xtensions Checkout Success Page. If your Opencart Shop would be your wife and these 3 modules would be your 3 lovely kids, it would complete your whole shop to a perfect functioning family. Of course also modern and good looking haha. Recommend these modules for everyone as a must have.

The best checkout module ever for opencart...extremely beautiful, simple and easy checkout process. I have never come across any checkout modules like this for opencart...I want to say, all One Page checkout modules all over are all the same...i personally dont like those but have no choice but to buy to replace the default checkout page.
Overall, since this comes with complete checkout framework which makes it stands out from the others.
Excellent Support and quick fix to a small customization required..completely love this module.

This seamless integration module raised our sells almost by 20% as their are less failure of payments while making through it. In fact, most of the customers are keen to put their payment credentials on merchant's site itself, so the credibility of site also goes higher with seamless option. The design and interface of this module is very sophisticated and the technical part is also perfect. Till the date, we haven't got any complaints of payment failure from our customers.
