-
The system holding your key data has no usable connector, or it is a black box that must not be modified.
-
The two sides use different authentication, data formats and event models.
-
Connecting two APIs directly works in a demo and breaks in production, because failures are not handled and nobody sees them.
-
Data lands in the CRM late, twice or not at all, and the team stops trusting it.
Integration middleware for systems that standard connectors cannot reach
A dedicated layer between your CRM and your on-premise, legacy or in-house system. The systems never call each other directly, so neither has to change. We build it, and we can also host and run it for you.
Looking for the full overview of integration scenarios? See custom CRM and ERP system integration.
Where standard integrations break
How the middleware works
Each piece has one job, so failures stay small, visible and repeatable.
Events
Jobs
API calls
Retries and dead-letter queue
Monitoring dashboard
Security
Which systems it connects
-
Proven in production with HubSpot and an in-house admin system.
-
The architecture does not depend on the CRM: the same pattern applies to Salesforce, Pipedrive, Dynamics 365, Zoho or Odoo on one side.
-
On the other side: ERP, proprietary, on-premise or legacy systems, as long as they expose an API, webhooks or a database we can poll safely.
-
We start with a discovery of your API and data model, so you know what is feasible before you commit.
Middleware, iPaaS or a ready-made connector?
We recommend the lightest option that does the job.
Ready-made connector
iPaaS (Make, n8n)
Custom middleware
Ways to work with us
The three can be combined.-
Build
Discovery, design, development, testing in a sandbox, launch and hypercare. Delivered by a team that has done it before.
-
License
The reusable middleware core, adapted to your systems and customized to your processes.
-
Run
Hosting, monitoring, SLA, change requests and further development, so the integration stays healthy after launch.

Where it fits
-
In production at Slevomat: two-way sync between an in-house admin system and HubSpot as the central CRM for sales teams across several markets.
-
Manufacturing companies with industry-specific ERP systems that have no ready-made CRM connector.
-
Companies running older on-premise systems that cannot be changed or replaced any time soon.
-
Platforms and marketplaces with a proprietary admin system that is the source of truth for partners, orders and contracts.
-
Businesses with several national or business-unit instances of the same system, each with its own data.
-
Teams that need the CRM, the ERP and the finance system to agree on deals, invoices and payment status.
-
Organizations with corporate single sign-on that need a controlled, limited-access bridge between web or SaaS tools and the people who maintain them.
Not sure whether you need middleware?
Book a free technical consultation. We will review your systems and tell you honestly whether a connector, an iPaaS flow or custom middleware fits. More integration scenarios are on our CRM and ERP integration page.
Frequently asked questions about integration middleware
No. The middleware sits between the systems and uses their existing APIs or webhooks.
We use scheduled polling or an event sender on your side. We confirm the approach in discovery.
Temporary errors are retried automatically. Permanent errors go to a dead-letter queue with an alert, and your team replays the job with one click after fixing the data.
Yes, with a defined SLA that covers hosting, monitoring and support. Alternatively we hand the solution over to your IT team.
No. HubSpot is where it is in production today, but the architecture is CRM-agnostic and fits Salesforce, Pipedrive, Dynamics 365, Zoho, Odoo and others.
When objects are standard and logic is light. In that case we recommend a ready-made connector or an iPaaS flow and say so in discovery.

HubSpot Marketplace review
We’ve been working with Forecom for a few years now to manage our HubSpot setup, and it’s been a really good experience. They know HubSpot inside out, but what really makes the difference is how they work with you. They’re approachable, responsive, and just easy to collaborate with. Over time, they’ve started to feel more like part of our team than an external agency. I’d absolutely recommend working with them.

He and his team were always very helpful, reacted in a timely manner and provided useful practical tips and answers to the questions asked. Thanks to their Diamond partner status, they also helped us unstopper progress when HubSpot's in-house team wasn't being particularly responsive. They have definitely aided our startup in the pre-purchase phase and the early days of being on HubSpot.

They expertly managed the entire migration process from Pardot to HubSpot, providing comprehensive training, demonstrating how everything works, and configuring even the most complex aspects of the system. Their deep understanding of overall marketing strategy significantly contributed to optimizing our forms, lead processes, and conversions. I highly recommend working with Forecom, and we continue to rely on them for various consultations.

We recently engaged with FORECOM for a comprehensive project involving the implementation of HubSpot Marketing Hub, including in-depth consulting around CDP Segment and several complex integrations and workflows. They took the time to understand our specific needs and tailored their solutions to ensure seamless integration with our existing systems. We highly recommend FORECOM for any business looking to implement or optimize their HubSpot Marketing Hub.

Judging by my experience so far, I am convinced that there are not many marketers on the market who are so strongly focused on real business results. Lukas and his Forecom are proof of that. Lukáš himself is not only a great strategist, but also an expert who knows exactly how important it is to properly link marketing and sales and what to focus on when you need to generate valuable leads. He has helped us not only jumpstart our performance marketing, but actually get it to a solid level on a minimal budget. He quickly grasped our current opportunities, innovatively grasped our inbound and was able to combine it with the traditional outbound approach typical of B2B SaaS enterprise companies of our type. His intimate knowledge of HubSpot is a huge advantage. With Lukas as a growth marketing expert in place, I can be sure that thanks to his sales overlaps, complexity in thinking, broad insight into new trends and last but not least his empathy and ease in communication, we are well on our way to further successes together.

Forecom has helped GoodData with complex migration from Marketo to HubSpot including integrations with Salesforce and many other Sales & Marketing tools. They were a great partner during the initial project and continue providing excellent services in the management of daily business activities and have always been very flexible, delivered on time and as requested. Overall, it is a pleasure to work with them and we will continue our cooperation.

Forecom was introduced to our processes through the implementation project of HubSpot as our Marketing Engagement platform. They have a greate expertise in implementing HubSpot and designing the processes in integration with Salesforce. Their expertise was essential to the progress. We appreciated the quick support and going extra mile in cross-functional operations and close collaboration with RevOps. Eventually, Forecom became our true partner supporting MarOps being included to many internal projects. Additionally, it is a personal pleasure to work with all the Forecom consultants and mainly Lukas who is always here to have our backs and provide a very personalize approach. I would recommend working with Forecome!

We worked with Forecom to migrate 2 HubSpots into one account that would preserve the functionality of both. The collaboration was very comfortable because they came up with their own solution and carried it out within (tight) deadlines, whole keeping in mind our already established processes. They ensured a smooth transition where team members were able to fully use their current HubSpots until the last day before the migration and from the second day onwards started using one common HubSpot without any negative impact on their workflow. We were very pleased with the activities they provided and can recommend working with them.

We are working with Forecom mainly on modifications to our website, but also on general marketing cooperation such as improving SEO or generally setting up processes in HubSpot between marketing and sales. Even though the website was not made by Forecom but by another company they are very quickly able to find a solution to any problem or incorporate our ideas. The cooperation with them is really great. They never deal with unnecessary things, communication is always direct and the work is always done on time and as agreed. We highly recommend Forecom to everyone.

I worked very well with Lukáš Lískovec, mainly thanks to his comprehensive know-how in the field of digital marketing combined with very good analytical thinking.

We started working with Forecom during the process of migrating all data from ActiveCampaign to HubSpot. Not only did we need to move all of our data, but we also needed to optimize our existing marketing and sales processes. Forecom has been a great partner along the way, helping us focus on what's really important and ultimately achieve our marketing and sales goals. We highly recommend them!

Lukáš prepared an analysis of the competition for us, which became one of the bases for our marketing plan. He always responded immediately and kept everything we agreed on.
