Head of Engineering Small-Business (50 or fewer emp.) 11/17/2025 "Exceptional Support and Rapid Feature Releases" 4.5/5 What do you like best about Merge Unified? Their support staff is truly world-class. Our company has collaborated with many third-party clients, and Merge's support team stands out as top tier. I also appreciate their consistent schedule of feature releases. The team members seem to have significant autonomy, so whenever I raise an issue with support, it genuinely feels like the product and engineering teams are giving it real attention and priority. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? I feel that their enterprise sales process could have shown a bit more flexibility. Although we did receive a modest discount as a startup, it was crucial for us to test specific features to determine if the enterprise plan suited our needs. We requested some extra time to evaluate these aspects, but they were not willing to accommodate us. Since we operate in a similar field, we understand the necessity of having sales deadlines and clear resolutions, but it truly seemed like they could have been a bit more accommodating.

The level of support from the Merge team is exceptional, specifically our Account Manager, Jemma, who is proactive, professional, and incredibly quick in responding. The integration with Pylon for support works fine. Beyond day-to-day help, Merge is genuinely invested in our success, actively seeking feedback to help shape their product roadmap, making us feel like a true partner. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? One area for improvement would be adding input validation for the ISU field within the Merge Link UI. Implementing this during the initial onboarding process would help flag incorrect values at the point of entry, streamlining the setup for end-users. Also, provide better, less generic error messages from the /employees endpoint (or create a dedicated validation endpoint). This would allow users to realize their ISU is incorrect and self-correct the issue without needing to contact support Review collected by and hosted on G2.com. What problems is Merge Unified solving and how is that benefiting you? Merge solves the high cost of integration maintenance and data fragmentation. For us, this means our engineers spend more time on innovation and our sales team rarely has to turn away a customer due to a missing HRIS integration. Review collected by and hosted on G2.com.

Mid-Market (51-1000 emp.) 4/24/2026 "Seamlessly consolidates IdP and HRIS platforms" 5/5 What do you like best about Merge Unified? I think the core model of Merge Unified is great, especially how it consolidates every vendor into a single API for us to integrate with. They have a solid understanding of their position in the marketplace and offer an ecosystem of people, documentation, and services that support us in building and delivering a new product offering. There's never a question we can't answer or a resource they haven't created for both internal and customer-facing documentation and enablement. The initial setup was as straightforward as a backend user account integration could be, and we could self-serve through the proof of tech and implementation with human support from solutions architects when needed. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? Some features we need and are excited about are paywalled behind add-ons or more expensive packages. It's the only part of the customer experience with any friction. Review collected by and hosted on G2.com. What problems is Merge Unified solving and how is that benefiting you? I use Merge Unified to integrate different IdP and HRIS platforms with my SaaS platform for enterprise user account management, which was impossible to manage at scale before.

Senior Technical Specialist / IT Computer Software Enterprise (\> 1000 emp.) 11/6/2025 "Effortless Integrations and Rapid Scaling with Merge" 5/5 What do you like best about Merge Unified? As a developer and now software dev manager I know the headaches of supporting integrations. Just 1 integration can be a lengthy endeavour to support ; Merge handles dozens and in a universal common model way which has allowed us to not only add new functionality to our product quickly but also scale to so many platforms without any additional lift. That is a HUGE value add! Review collected by and hosted on G2.com. What do you dislike about Merge Unified? Not a dislike but the data normalization can work against you at times. Sometimes you need the actual underlying data in its true form in your sync. They obviously thought of this though and provided a simple flag in the API call to return the raw data instead of the normalized version. I think though that most use cases would benefit more from the normalization though Review collected by and hosted on G2.com. What problems is Merge Unified solving and how is that benefiting you? Merge is allowing us to provide HR data sync in our products. This is a top tier level request from clients and we were able to quickly provide this using their service. The biggest win here is unified support across dozens of HR platforms at once. If we had to do each one manually it would literally take years of development.

The documentation for each of the usages of the Common Models are fantastic. It's easy to find everything I need. When implementing we would have weekly meetings with a Merge technician that was genuinely invested and interested in what we were doing. There was maybe 1 or 2 issues that arose that we identified and Merge either explained what we were doing wrong, or implemented a new feature for us that ended up being useful for other clients. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? We were set up with a "sandbox" UKG account that had simulated real data. The problem was that this sandbox was shared across multiple other Merge clients which caused some issues when we were trying to test things and getting back very strange data. Review collected by and hosted on G2.com. What problems is Merge Unified solving and how is that benefiting you? We need to be able to connect to many client's HRIS systems. To handroll connections for all the various HRIS providers would me a monumental task. Merge's Common Models made it much easier to ETL client HRIS data into our own system.

Implementation Manager Small-Business (50 or fewer emp.) 10/2/2025 "Much needed product with excellent customer service" 4/5 What do you like best about Merge Unified? There’s two main qualities that make Merge stand out: 1. They are meeting a previously unmet need and allowing small to medium sized businesses thrive early on with much less hassle on the customer’s end during implementation and onboarding, which significantly improves customer experience. Especially when the end user is non-technical, Merge is a game changer. Without Merge, companies and customers would need to work together to find their own solution to integrate the customer’s data which has proven time and time again to be extraordinarily complicated based on different, complicated systems on each end (product vs customer). Then, add end users who are non-technical on top of that, and you’re constantly holding your breath hoping the customer is still going to use the product after a frustrating onboarding process to get their data integrated into your product. Most people don’t understand how complicated custom APIs can get and the amount of labor and work that goes into each one. Merge makes it so companies don’t have to create highly custom solutions or rely on existing limited APIs to integrate. 2. The customer service is phenomenal. They make it incredibly easy to ask questions, get help, and get clarification on any item you’re working on with a customer. This makes a massive difference, especially as they add in new functionality and new integrations with new linked accounts/systems. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? The common model mapping depends on each system. Some systems are able to integrate smoothly while others are more complex. Some integrations don’t support all the data required, leaving us to solve for some missing data issues through manual loading processes. Sometimes we can find the missing data and remap through remote data or pass through data, but sometimes it’s simply not coming over at all through the API, and we need to find a custom solution for those. That being said, functionality is constantly improving and the customer service is always there to help. Review collected by and hosted on G2.com.

I really appreciate the large collection of integrations they offer. They make the setup easy with thorough documentation and dedicated support. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? Sometimes partner requirements can be better streamlined. Beyond build, HRIS providers may have additional review processes or requirements. I find that process to be often time-consuming and unclear. It would be great if Merge was more informed or involved in that process. Review collected by and hosted on G2.com.

Founder & CTO Small-Business (50 or fewer emp.) 7/17/2025 "Must-have Unified API Platform" 5/5 What do you like best about Merge Unified? As a compliance automation platform, the ability to seamlessly connect with our customers' existing tools is core to our business. Merge's Unified API has been a game-changer for us. By handling the integration layer for HRIS and Ticketing systems, Merge saves our engineering team a ton of time that would otherwise be spent on building and maintaining individual integrations . This allows us to focus on our core product and accelerate our roadmap. Review collected by and hosted on G2.com. What do you dislike about Merge Unified? More categories and even more and deeper integrations are always something that can be worked on, but the team is very responsive about feedback and inquiries we have. Review collected by and hosted on G2.com. What problems is Merge Unified solving and how is that benefiting you? For our product to work, we need to pull data from our customers' HR and ticketing systems. The main problem we faced was the sheer variety of platforms our customers use. Building each integration one-by-one would have been a huge resource sink for our engineering team. It's not just the initial build; it's the long-term maintenance, handling API changes, and dealing with edge cases for each specific platform. Merge essentially takes on that entire problem for us. By integrating with their Unified API, we get access to a whole category of tools through one connection. For us, the benefits are very practical: - Freeing up our developers. We're a growing team, and we can't afford to have engineers tied up maintaining dozens of third-party integrations. Merge saves us an estimated thousand hours a year, which we can now invest in building our core product features.
 - Onboarding customers faster. When a potential customer asks if we integrate with their specific HR system, we can almost always say yes. It removes a major sales blocker and lets us get customers up and running on our platform much more smoothly.
 - Building better features. We use Merge to handle things like automated user provisioning. We wouldn't have the capacity (or would need to sacrifice other priorities) to build these kinds of features across so many different systems without a tool like this handling the integration layer.
