Koongo offers many possibilities for managing marketplace integrations, but our recent experience with the bol integration was frustrating.

A repricer that was set to Monitoring Mode turned out to still block updates to our active offers due to MinimumPrice errors. As a result, an important change to our delivery promise was not correctly sent to bol. For a small business without its own IT department, hidden technical dependencies like this are extremely difficult to identify.

It also took some time before support focused on the actual issue. Eventually, Pavel identified the cause, disabled the repricer, and ensured that the synchronization worked correctly again. He certainly deserves credit for resolving the issue.

My main recommendation for Koongo is greater transparency. Features in Monitoring Mode should not block critical updates without a very clear warning. Issues that can affect seller performance or even the status of a marketplace account should be flagged proactively and much more visibly.

Koongo is a powerful platform with good technical support once the right issue is identified, but usability, transparency, and error reporting could be significantly improved for small businesses.

Tried there system and could not remove all the errors, so hired a freelancer and they still could not solve the problem. Did not get a trial and they took a months fee from us said they would refund our money then said no chance of A REFUND.
So would NOT recommend this system unless you want to waste money and time.

Koongo is currently one of the best integrators on the market. Their support, especially Raül is excellent and very helpful. I definitely recommend it.

The best application for integration at the moment. A large number of platforms for connecting, the ability to create a custom feed, excellent support service. 5/5 without a doubt.

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.
