We find the right one.

[Why Selleris]

CRM expertise without the vendor lock-in.

You can't recommend the right CRM if you only sell one. Working across HubSpot, Dynamics 365 and Bitrix24 means we see the market from three angles — and that's what turns selling into advising. We recommend the platform that fits your business, your team and your budget.

Platform-agnostic advice

Every recommendation starts with a side-by-side comparison of HubSpot, Dynamics 365 and Bitrix24 — three fundamentally different platforms covering marketing-first, enterprise, and all-in-one approaches. You choose based on facts about your business, not on what earns us the highest commission.

Honest guidance from day one.
Outcome-based by default

Every task gets scored before we touch it: estimated business benefit, our cost to deliver, and projected ROI. Tasks are prioritized by ROI — not by what's easiest or what shouts loudest. After delivery, AI analyzes the result and recommends the next high-ROI moves, so your CRM keeps compounding instead of stalling at go-live.

Hours don't measure value. ROI does.
Hosted, monitored, and secured on Azure

Your CRM and custom applications run on Microsoft Azure under our management — deployment, scaling, backups, 24/7 monitoring. Security is a first-class commitment, not an afterthought: hardening, monitoring, and optional penetration testing keep your systems and customer data protected.

One team owns uptime and security.

Raphael Schönen
Operations Manager at Linxys

"We have been using the Bitrix24 Enterprise platform for around 5 years and have switched our Bitrix24 partner to Selleris. I must say that, despite being quite into the platform, we have experienced a high level of service and skilled staff from Selleris. The result has been that our platform today is even better, more widely implemented, and generally more valued by the organization."
