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.
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.
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.
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.

"We have been working with Selleris for a year. They are really enthusiastic with sharing their experience and CRM/sales best practices. Also Selleris people are creative and have a solution even for difficult cases. Recommended."

"Selleris has been an exceptional Bitrix24 partner, providing expert support, customized solutions, and strong commitment. They understand the platform, meet deadlines, and focus on results. If you need a reliable and knowledgeable Bitrix24 partner, choose Selleris."

"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."

Choosing the right CRM is a strategic decision — not a software purchase. Here are the questions our clients ask most before starting a project with us.
Most mid-market migrations take four to ten weeks. Data volume, the number of custom objects, and how many automations must be rebuilt are the biggest factors.
For a typical SMB migration, plan one to two weeks of preparation for every week of technical import work. Cleaner source data shortens this; years of unmanaged records lengthen it.
Not with a proper process. We take a full backup, run a test batch, and reconcile record counts after the full load. Salesforce-specific constructs like Apex triggers are rebuilt rather than copied across.
Clean it before it reaches HubSpot — in the source system or a staging spreadsheet. Importing dirty data and fixing it afterward means correcting the same issues across far more records.
Yes. HubSpot Marketing Hub connects to Salesforce through a native two-way sync, so you can add HubSpot's marketing engine without a full migration — a common first step for teams not ready to move entirely.
Custom fields you actively use should be recreated as HubSpot properties with matching types. Fields nobody has touched in a year are a good opportunity to leave behind and simplify.
Cost depends on data complexity, the number of automations and reports to rebuild, and any custom integration development. After a discovery phase you receive a fixed-price scope rather than an open-ended hourly estimate.
