The number of integrations is astounding. Implementing Merge.Dev gives access to so many companies, it's never going to lead to regretting the license. Review collected by and hosted on G2.com.

I'd like to see more sandboxes. It's next to impossible to verify a product integration against some of these companies without a hefty investment in accounts. It would be amazing to use merge.dev to prove out connections so you can be sure of what your product can support. Review collected by and hosted on G2.com.

Merge helped us expand our client offerings as well as helped us improve our internal processes. Their list of possible integrations have helped us create features that our clients have been asking for. It also helped us provide our clients with data analysis of their hiring and retention practices.

It was easy integrating with Merge using their API documentation. It made it much quicker for us to implement our client's ATS and HRIS data into our platform so that we can provide them with key metrics and data analysis. We've also started planning out how to use their other offerings for future feature requests. Their dashboard is easy to use and helps us manage all of our integrations in one place.

The biggest selling point, that made us choose them over other products, is that they make it so easy to map disparate data into our schema. They have a great way of consolidating different HR provider's data into their platform. They also let you use custom types to add specific mappings you want to include in the data ingestion process.

Merge's customer support is excellent. We recently had to fill out and submit an application to use an external HRIS system and they helped us through this process. Review collected by and hosted on G2.com.

There’s sometimes a mismatch between ATS and HRIS offerings but Merge has been quickly adding new integrations in each category.

Some HR solution providers need extra paperwork to get started but Merge helped us fill these out and get our application submitted. Review collected by and hosted on G2.com.

Merge is simlpe to use and easy to navigate through. Review collected by and hosted on G2.com.

Sometimes not sure what certain errors or issues mean, choosing between integrations for a single customer is hard bc tehy aren't differentiated. Review collected by and hosted on G2.com.

Merge has been a game-changer for our integration needs and enabled us to scale our integration platform exponentially faster than we could have building each integration in-house or relying on third-party contractors .

First, the scalability is impressive. We don’t have to worry about managing the unique authentication requirements for each HRIS or keeping up with API changes—Merge takes care of it all seamlessly. This saves us countless hours of maintenance and ensures our integrations stay reliable.

Second, the flexibility of their common model when combined with their custom mappings feature is outstanding. The common model provides a robust default structure that works for most use cases, but, with their custom mappings, it’s also extremely customizable. As a result, when a customer asks, “Can you handle this unique scenario or custom field?” we’re almost always able to say, “Yes, we can do that,” thanks to Merge’s flexibility and extensibility.

Their support is another standout feature. The response times are next-level, and it’s clear the team genuinely cares about helping their customers succeed.

Lastly, debugging is refreshingly simple with Merge. Their API tester and detailed logs make it easy to identify and resolve issues quickly, keeping our development and debugging processes smooth and efficient.

Merge enables us to focus on delivering value to our customers rather than worrying about the complexity of integrations. Review collected by and hosted on G2.com.

We did encounter quite a few bugs early on, but this seemed to be due to lower adoption of the HRIS integrations we were leveraging at the time. The platform has become much more stable since then, and we rarely experience issues now. Additionally, when we did encounter problems, their support team was very responsive and communicative and did everything they could to resolve them as quickly as possible, which helped mitigate any frustrations.

Another consideration is that some companies Merge integrates with may pose additional challenges during the integration process. For example, larger providers like ADP, Paylocity, and Rippling often require going through partnership processes, which can take time. This is not an issue with merge - these are challenges you’d face regardless of using Merge, and their team provided excellent support to navigate these obstacles more smoothly than we could have on our own. It’s just worth noting that not every HRIS integration is entirely ‘turnkey,’ and some HRIS platforms may also charge customers for API access. Being aware of these nuances and differences with each HRIS can help in planning your integrations effectively. Review collected by and hosted on G2.com.

The most useful thing is a combination of several things:

- a wide range of integrations

- a wide range of supported languages ​​for SDK + ready-made solutions for Frontend SDK

- a convenient and fast flow for linking accounts for our end users

- a diverse set of tools in the admin panel such as webhooks, sandbox, test api

- clear onboarding during registration in the admin panel Review collected by and hosted on G2.com.

- price (it would be possible to break down the pricing policy depending on the modules that are needed, i.e. why overpay if, for example, only one ATS module will be used)

- sometimes a certain api is poor in functionality, for example, certain batch requests such as POST requests for creating candidates for ATS systems are missing

- more advanced multitenancy is missing Review collected by and hosted on G2.com.

The most helpful thing about Merge is the fact that we don't have to manage the actual integrations with the accounting systems we're interested in (QBO/Xero). Upsides are quick connection to users' accounting systems, no need to manage keys on behalf of the users, and the ability to sync most writes instantly. Review collected by and hosted on G2.com.

So far my experience with Merge has been good. It's able to collect/read/write most of the data I'm interested in to the accounting systems we integrate with (QBO & Xero). However, there have been a handful of times where the documentation indicated support for certain endpoints and it ended up not actually having support for it with the promise of the fix coming within the quarter or following quarter. A lot of the time the promise has been delivered. It would be nice if there was an easier way to setup webhooks programmatically so that we can sync merge accounts on the fly for data written via passthrough.

We rely on Merge to support our Accounting and HRIS integrations. From the start, we knew integrations would be critical to our success, and we set a high standard for selecting the right partners.

Over the past year, our experience with Merge has been exceptional. Their platform has enabled us to efficiently expand integrations across multiple categories, allowing us to stay focused on our core product. When unique challenges or support questions arise, the Merge team is always there to provide prompt and effective solutions, helping us accelerate our development and stay on track with our roadmap.

Managing integrations—whether it’s resolving issues, applying updates, or ongoing testing—can be a significant burden on engineering teams. Merge has completely taken that load off our shoulders, saving our engineers hundreds of hours annually and freeing them to focus on building what matters most. Review collected by and hosted on G2.com.

Some their integration partnerships, can be "difficult" to work with. There have been times where the integration has gone down, and it hasn't been on Merge, it is has been on the vendor they are integrating with. The good news, is that Merge was super collaborative with us, and talked us through everything. Review collected by and hosted on G2.com.

We use Merge to pull in data from HRIS software to help companies provide services to their employees. We could have spent hundreds of hours building and maintaining custom integrations across the 20+ integrations we provide via Merge today. Instead they make it fairly easy to connect to different HR systems and safely pull in employee data.

Their customer support tends to respond within a business day typically, especially if you get the plan with a Slack channel.

I like how easy it is to show my customers that we aren't pulling in sensitive payroll data to the API (as our service does not need that data, though I believe Merge can use it if your service needs it) because you can toggle which fields sync on and off very easily. Generally HR managers can also decide whether Merge has access to that information at all.

I am not an engineer, just an administrator that trains customers on setting up these integrations, but the software is straightforward enough that it's fairly intuitive for me to use their admin site. Review collected by and hosted on G2.com.

Some HR systems are very easy to connect to, and all they require is the HR admin to log in with a username and password. Some HR systems, like ADP, are more complicated setups that take 20+ minutes and if you mess up a step you need to start over completely. I think that is more in the nature of the original HR software than on Merge's side, to be fair.

Their documentation could be better, sometimes it is out of date compared to UI changes in the HR system I'm trying to implement. Troubleshooting errors can be a little complex. Review collected by and hosted on G2.com.

Easy to start with.

Good if you would like to have any integrations at once. Review collected by and hosted on G2.com.

The docs are so-so.

Most of the time, it feels like there is no support.

I can't get answers to share with my customers. I would never use this with customer-facing features.

With today's tools, building an integration using AI agent, it doesn't make sense to use merge as they have no support Review collected by and hosted on G2.com.

The thing I like best about Merge has been the support we've gotten from the team. The product and documentation are definitely good, but it is inevitable to run into challenges with integrations. The customer success team has gone above and beyond in helping us to meet deadlines and the needs of our customers. Review collected by and hosted on G2.com.

The thing I like least about Merge is that I wish they were just focused on Applicant Tracking System integrations. In my role that is the only type of integration we are focused on, and I think the experience could be even better if Merge focused solely on the ATS space. This is definitely a selfish perspective. If we ever aim to integrate with HRIS or CRM, I'm sure we will be happy that Merge has more to offer. Review collected by and hosted on G2.com.
