What merchants think

Feedback submitted

Merchants describe this app as a powerful, reliable tool for listing and managing products across marketplaces like Amazon, bol.com, Zalando, Miinto, and Google Shopping. They highlight strong automation for feeds, stock, prices, and orders (including returns on some channels), plus advanced filtering, attribute and price editing, and product mapping. Some find setup complex, but many praise the fast, patient onboarding and marketplace-specific support.

Doenst work at all !
For each sale channel you need years to speak with customer support and they answer once daily and you must fix with them each channel which doesnt work at all !
I was use for years and I wrote over 1500+ emails with their customer and when we solve problem, new problem appear. This app change variants ad make them separated and system publish each variant separetly !
I used it for Wish and Amazon and this was horrible experience !
Also when Wish charged penalties, this app made me errors which costed me over 240$ in penalties !
Avoid this app at all ! I asked for refund and they didnt gave me it ! They present that Koongo has integration with marketplaces, but when you try it this doesnt work !

We're sorry to hear about your experience and surprised by the change from your previous 5-star rating. You've been a seasonal Koongo user for several years, repeatedly installing and uninstalling the app, and during that time, we’ve provided multiple trial periods, regularly reviewed your store data and implemented custom rules to ensure your product data met the specific requirements of marketplaces like Wish and Amazon, without requiring manual adjustments from your side.

We’ve always aimed to offer hands-on support and continuous assistance, responding promptly to your inquiries. Unfortunately, it seems we didn’t receive a response from you on several occasions.

We truly appreciate your feedback and the opportunity to improve our service.

We have wasted literally hundreds of hours trying to get this app to work on our own and with their help. It sets up OK but the product filters and category mapping keep changing over time on their own. This is a huge problem if you have automatic downloads to your merchant center. They did assign an agent to our problem but they could never figure it out. Today, rather than spending my time redoing all our feed filters and category mapping again, I am looking for a new app.

We regret to hear about your experience. The app does not change filters or any mapping automatically. We can investigate further to determine what triggered the modifications, please reach out if you'd like to re-connect your store to Koongo.

Worst support. This app do not make it easy for you to list on markedplaces in fact so many errors and bad support you might just upload your products to the selected marketplace, and update manually for each sales.

Dont install. AND CMON 25 DOLLER FOR A FEED WITH NO SUPPORT!

We’re sorry to hear about your experience. Our records show that you didn't use the app for even half a day, installing and uninstalling on the same day. Despite offering help multiple times, we didn't receive a response from you. If you're still interested, please reach out to our support team, and we'll assist you in getting the most out of our app.
Thanks!

Thanks for your review. I'm sorry about the issue but it is not possible to adjust listing manually and automatically via API at the same time. The listing changes overwrite each other. Also, if your listings were adjusted manually in the past it was necessary to backup your Amazon listing before API connection adjustment.

I'm sorry but there was no 24-hour delay in reply, we started to help you to restore Amazon listing once the problem was reported, working on that also over the weekend.
