Alt-team Company offers CS-Cart integrations:

CS-Cart design integration

Once a designer finishes unique mock-ups for the online store, you have to use a CS-Cart design integration service to transfer all created conceptions to HTML code. Alt-team's integrators can provide you with such service.

CS-Cart payment integration

Even though the CS-Cart solution has been integrated with more than 50 popular payment systems, sometimes it is necessary to add new payment methods to an online store. We are pleased to help you with this problem.

CS-Cart shipping integration

CS-Cart offers the most popular delivery services in the world: Fedex, UPS, USPS, DHL, Australia / Canada / Swiss Post, and Temando. But there are cases that demand the use of other delivery services due to their low prices, the convenience of certain shipping processors in your country, or the trade zone. We can integrate any shipments with the CS-Cart system.

Integration of third-party systems with CS-Cart

Even though the CS-Cart solution is by default integrated with a wide range of third-party systems, there may be times when you feel a lack of certain services. According to our experience, many third-party services find their niche in the e-commerce market and become popular and widespread in certain areas each year. So, we can solve this problem for you too
