Review summary

Created with AI, based on recent reviews

Many customers appreciate the platform for its ability to connect them with clients and experts, finding it an outstanding space for professional collaboration and high-level consulting services. They often describe the website as excellent and professional, making it easy to find clients and ensuring projects are funded before work begins, which facilitates negotiations and timely project completion. However, a significant number of people express dissatisfaction with payment delays and the overall payment process, noting that funds are often withheld or not released on time, leading to financial pressure. There are also widespread complaints about unresponsive customer service, with many reporting that their emails and support tickets go unanswered for weeks or months, making it difficult to resolve issues, especially concerning payments. Some users also find the platform's fees high and the available payment methods limited, suggesting that alternative options would improve flexibility and reduce wait times.

I was able to meet a hard working statistician who met my needs. Unfortunately communication with the support staff via email is poor and contributed to a delay in payment of the statistician.

My first Kolabtree project

The project assigned to me was my first project on Kolabtree. It was from a verified client, I was happy with the project assigned with clear instructions and the client was also happy with the finished project. I would like to thank Kolabtree for the user friendly experience for a new freelancer using their website.

Excellent value add and easy to use

Kolabtree was new for me and I must say the experience was really great, easy, and very transparent. Now I know where to go with my projects, especially for those that require some specialist skillsets.

Happy with the platform overall, but it feels a little 'bare-bones'

I've only been on the platform for about a month (during the holidays!) but have already had two great encounters; understanding clients with no payment issues. And I've had similarly pleasant interactions and possible future collaborations with others. I really like the academic focus of the platform (though a disproportionate number of listings appear to be related to chemistry/product development, which is not my area of expertise), and the fact that a simple, (pricy!) 20% charge is levied on bills; which is not prorated to lifetime billing, e.g., nor are proposals charged. And the website/platform works quite well and is well-organized in most ways, with a few exceptions: It's necessary to duplicate tabs since there's no context menu for the alert icon entries; projects cannot apparently be filtered above budget thresholds nor subject matter, and past proposals are grouped in a bit of an unruly heap which can be handled with some filters but is wanting nonetheless. Overall, I'm happy with the platform, but it feels a little 'bare-bones.'

Released funds never reached my bank account (are they using it?)

My client released the funds over a month ago, Kolabtree charged me the fee, yet I do not have access to "MY" money in my Payoneer account. I sent dozens of messages and received nothing. "ANY". No apologies. As another scientist exposing their hardships with this site here, I am also currently evaluating a lawsuit against them. I hope someone from the company finds out how bad they are as a company and changes

Good luck getting paid!

I am finding Kolabtree extremely frustrating. While the layout and the format is not as well organized as Upwork, I liked the fact that it is geared towards scientist. I was excited for my first project on the platform. I got a contract, I started working on it and I kept updating the client on the progress. Unfortunately there was no feedback from the client. When I delivered the final product, I never heard back from him. I have contacted customer support at Kolabtree and they told me they were going to contact the client. Later they told me that they have not heard from him yet. Unfortunately customer service keeps dodging my questions on how long will it take for them to release the funds in escrow if they do not hear from the client. So far, it looks like, they will either return the funds to him or keep it to themselves. Definitely not worth my time to work with them again, it takes more time to try and get paid then actually doing the work. I wish they had a policy like Upwork to release funds if they do not hear from client within 14 days.

Edit: I am editing this review changing the rating from 1 star to 3 stars to reflect that eventually Kolabtree released the funds and started becoming more responsive. The New rating is 3 stars and not higher because they started handling things right only after I wrote this review. I hope, I can give them a 5 star rating in the future if they start fixing problems before you write them a negative review.

Please note, our internal team has reached out to the client for a confirmation to release the payments. However, we have yet not received any response from the client as yet. Nevertheless, we want to let you that we have reached out to him again with the final notice to release the payment.

We assure you Kolabtree does not keep any funds with itself and releases the funds as soon as we get the permission to do so from the client. Similarly, as mentioned we are taking all necessary actions for this case as well.

We are proactive to help our users and thus request you to reach out to us for any queries.

Very good platform

Very good experience. Easy to find and connect with a freelancer with the skills I needed. The GUI is also excellent and made it easy to navigate and communicate. I gave 4 rather than 5 stars because one difficulty I had was with payments. My institution (a university) would allow payment to the wallet ONLY after receiving an official invoice, but Kolabtree will only provide an invoice after the host pays the freelancer from the wallet. We found a work-around but it slowed us down considerably. I will continue working with Kolabtree if they can resolve this issue and find a way to accommodate the purchasing protocols at universities.

Hi Bob,
Thank you for your feedback. We appreciate this as it helps us work better.

Kolabtree signs a supplier form for every University we work with and this was signed with Millersville University as well. We apologise if this was a delay from our end.

However, having this signed now (as it was a one time process) you can post projects and use Kolabtree more often. We will have our team reach out to you to help you how the invoice system work and thus this should definitely not be a blocker for any of our users.

We once again assure you there would be no blockers for your use of Kolabtree and are happy to extend our services to you. Looking forward for more interaction.

Kind Regards

20% service fee is too high, curation and platform need work

The 20% service fee seems too high and makes it much harder to fit within typical client budgets. It would also be preferable if this service fee was client-funded and not freelancer-funded, so that freelancers don't have to deal with the tax deduction on this fee.

The curation of projects could be improved. The majority of recommended projects are low quality: either too low of a budget, not relevant to my experience, or an unreasonable scope of work. The projects by verified clients do seem to be of higher quality.

The process for bidding on a project also feels clunky. Often specific milestones and deadlines cannot easily be established based on the small project description provided by the client; some sort of back and forth discussion is needed to establish these details. It seems to me it would be easier to just describe why my experience is a good fit for a given project, the client can decide if I'm a good fit, and then we can discuss to determine milestones and deadlines. Having to determine these beforehand in the proposal leads to wasted time and effort.

Hi John
Thank you for your review, we greatly appreciate all feedback we receive as it helps us improve our platform for our users.
We would like to highlight our milestone feature. Adding a milestone to the proposal is always optional. You can submit a bid without a milestone. Further, you call always edit and add a milestone after discussion on the project with the client.
Also, for low quality of projects we action to close these projects immediately. We do not want our experts to look at these projects and thus the projects are closed by our team.
Our internal team always makes sure that the experts invited for the project are experience in the field. However, we shall be more cautious on sending invitations to you and in general for projects.

Wishing you all the best!

Best Regards

Took a while to get a refund

I asked for a simple data-mining service. I waitet much longer for the delivery than agreed inititally with the freelancer. The freelancer never delivered. Kolabtree agreed to abort the project, however, I have never received back my payment (that was secured on kolabtree as a 'security' for the feelancer, which was 400 USD).

So, not only had I to do the entire work again (after loosing several months with the freelancer and asking for corrections that never happened), I have also lost 400 USD (which kolabtree just keeps without any justification).

Therefore, I absolutely not recommend to use this platform. I also never received an answer from Kolabtree. I really feel scammed and angry at this point of thime.

Update: Afer this review and several more e-mails, I have received a refund - so changed the review. However, since this was quite a timeeffort I have not given the 5 stars.

Clients do not make payments

A client took the source code for the project and did not pay me. The team at Kolabtree did not do anything about it. They can't offer protection to their freelancers.

I do not recommend this platform.

Dear Vinita,
Thank you for your review, we greatly appreciate all feedback we receive as it helps us improve our platform for our users.
We would firstly like to apologise for the inconvenience that has been caused by this situation, we are working hard to come to a resolution.
Once a project has been confirmed and an expert has been officially hired, the client is informed that they are required to fund the project in order for the work to begin. Simultaneously, the expert is also notified that they should not be sending over any of the deliverables, until the project wallet has been funded.
Cases like this are rare, and our clients have a good understanding that the projects must be funded prior to any deliverables being received.
Unfortunately, after several attempts of reaching out to the client regarding this matter, there has been no response. Rest assured (you will be reimbursed? For this project).
Kind regards,
The Kolabtree Team”

Impossible to delete the account

Contacted support to delete the account 6 months ago and still no response. My profile is still on and I keep getting spam from something I no longer use.

By the way, not allowing freelancers to delete the accounts without contacting support is absurd.

----

Edit. The problem was solved one day after this review. I acknowledge how fast it was, but I am not changing the review because not being able to delete the account whenever you want is terrible.

24 months with Kolabtree

The platform is easy to use in general and allows for a fluent relationship with the client.
The main drawback found so far is the difficullty to change baking details. This is something that should be fixed. Also I found impossible to modify or add new milestones (and change fees) to an ongoing project. A new process has to be opened in case you need any ampliation of a current project.
