As I mentioned before, IXXO Multi-Vendor has two options of purchase the license: lifetime license and leased.
CS-Cart Multi-Vendor costs $1,450 almost as IXXO Multi-Vendor perpetual license which price is $1,495.
Actually, it's good option to pay annually - you may pay less than full price and if the virtual mall software won't satisfy you, it will be less painful to pay $559 instead of $1495. But what becomes when the developer finishes supporting the product? You have multi-vendor license which expires within a year and what will you do for not stopping your store?
But CS-Cart Multi-Vendor has 30 day money back guarantee, so if the multi vendor ecommerce script won't fit your demands you'll have full refund.
Now let's speak about additional payments.
CS-Cart Multi-Vendor provides 1-year free subscription plan with license purchasing Then it costs $385 usually. But within 1 month from active subscription end you can purchase it for $245.
Also with CS-Cart Multi-Vendor purchase you get 3 months of free technical support. Later you will have to buy support credits
to have an access to tech.support. The price is $165 for 100 credits. Each contact to technical support is rated from 5 to 20 credits usually, so you can estimate approximately. Don't forget, CS-Cart has huge community with forum where you can ask your question for free and get answer.
And what's with IXXO Multi-Vendor?
The upgrades are available in 1 year after purchase, then you have to pay $179 within 1 month. If you don't, the upgrade subscription will be $523. With the license you get one month of free telephone support. After that month it will be $225 a year.
Don't forget about removing "Powered by IXXO Multi Vendor eCommerce" phrase for $159 and software installation by technical support for $69. By the way, you can have an installation of CS-Cart Multi-Vendor on your or recommended hosting for free, just ask sales specialist for that.
But I think all those additional payments for IXXO Multi-Vendor are not needed. Why do I? Oh, right! This marketplace builder seems to be dead.
