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 agencies bill you for hours. We bill you for outcomes — and we structure our work to make that possible.
Before we start any task, we estimate three things: the business benefit it's expected to produce (in dollars or measurable KPIs), our cost to deliver it, and the projected ROI. You approve work based on those numbers, not based on a vague scope. Inside the engagement, tasks get prioritized by ROI — the ones that produce the most value per dollar go first. The ones that don't justify their cost don't get built, even if they're on the original wishlist.
After delivery, we report on what was actually produced. Over time, this turns CRM work from an open-ended cost center into a portfolio of investments with known returns.
We specialize in HubSpot, Microsoft Dynamics 365 and Bitrix24 because together they represent three fundamentally different approaches to CRM: HubSpot is designed for marketing-first ease of use, Microsoft Dynamics 365 provides enterprise-grade integration within the Microsoft ecosystem and Bitrix24 offers all-in-one business collaboration at an accessible price point. Rather than selling dozens of platforms superficially, we master these three so we can give you an honest recommendation based on what your business actually needs — not what earns us the highest margin.
We start with your business — not with software. During a structured discovery phase, we map your sales workflows, team structure, existing tech stack, integration needs, and growth plans. Then we match those requirements against each platform's strengths:
HubSpot for marketing-led companies that need rapid deployment, intuitive UX, and strong inbound tools on a single platform.
Dynamics 365 for organizations already in the Microsoft ecosystem that need native integration with Outlook, Teams, Power BI, and Azure alongside CRM and ERP capabilities.
Bitrix24 for teams that want CRM, project management, internal communication, and collaboration tools in one environment — with a generous free tier and flat-rate pricing that doesn't penalize you for adding users. You get a transparent comparison, and the final choice is always yours.
Most CRM implementations go live and then drift — teams use what works, ignore what doesn't, and the system slowly stops reflecting how the business actually operates. We've built the inverse pattern.
After every delivered task, AI analyzes how the work performed against its ROI estimate, what it changed in the system, and what new opportunities that creates. You receive proactive recommendations — ranked by projected ROI, the same way we prioritized the original work — for what to build, automate, or optimize next.
This turns CRM from a one-time project into a continuous compounding asset. You're never stuck wondering what to improve. You always know what the highest-return next move is.
It's a fair question — and the honest answer is no, because of how we've structured the team and the delivery process. Two layers make this work.
First, our implementation methodology is platform-agnostic: discovery, solution architecture, data migration, configuration, UAT, go-live and hypercare follow the same structured process regardless of which CRM we're deploying. This is what 400+ delivered projects have refined — a system, not improvisation.
Second, we have dedicated teams certified in each platform. HubSpot specialists, Dynamics 365 consultants, and Bitrix24 developers don't cross over on core platform work — they own the platform-specific expertise inside our shared delivery framework.
Our integration layer is also standardized. All three platforms expose modern REST APIs, OAuth 2.0 authentication, and webhooks — which means our Azure-based integration patterns (using Service Bus, Logic Apps, Functions, and Data Factory) work consistently across HubSpot, Dynamics 365, and Bitrix24. One integration architecture, three target platforms.
The practical result: you get specialist depth on your chosen platform, plus a team that can give you honest cross-platform advice because they actually work across all three every week.
Full cycle means we handle every stage from start to ongoing support: business process audit, platform selection, solution architecture, data migration, custom development, third-party integrations, user training, go-live support, and post-launch optimization. You get a single accountable partner from first conversation to production — and beyond.
Timeline depends on scope, complexity, and how much data needs to migrate from your current system.
A HubSpot implementation typically goes live in 6–12 weeks — faster for single-hub deployments, longer when Sales, Marketing and Service Hubs are rolled out together with integrations.
A Dynamics 365 project with custom development and Azure-based integrations usually runs 3–6 months, depending on the number of connected systems and whether ERP is part of the scope.
A Bitrix24 deployment can go live in 3–6 weeks for standard configurations.We define milestones and deliverables upfront, so at every stage you know what's been delivered, what's in review, and what's next.
CRM implementation pricing depends on three factors: the scope of custom development, the number of system integrations, and the complexity of your data migration. As a reference point:
HubSpot implementations typically start at $12,000 for a focused Sales Hub or Marketing Hub deployment and range to $60,000+ for multi-hub RevOps projects with integrations, data migration and custom workflows.
Dynamics 365 implementations start around $25,000 for a standard Sales or Customer Service module and range to $150,000+ for enterprise rollouts with Azure integrations, custom development and ERP connectivity.
Bitrix24 implementations start at $5,000 for teams that need a working CRM without heavy customization, with most projects landing between $8,000 and $25,000.We provide a detailed fixed-price estimate after the discovery phase — no hourly surprises, no scope creep billed mid-project.
Azure provides enterprise-grade infrastructure for secure, scalable solutions — including Azure Service Bus for reliable messaging between systems, Azure Logic Apps for workflow automation, Azure Functions for serverless custom logic, and Azure Data Factory for data pipelines.
For Dynamics 365 clients, Azure is the natural foundation — both share the same cloud ecosystem, which simplifies authentication, data flow and governance.
For HubSpot and Bitrix24 clients, Azure serves as a powerful middleware layer connecting the CRM with ERPs, accounting systems, e-commerce platforms, and other business tools.
Security and compliance are built in. Azure meets the requirements of ISO 27001, SOC 2, HIPAA, GDPR and dozens of other regional frameworks — which means the same integration architecture works for a US healthcare company with HIPAA requirements, a European company under GDPR, or a global business with both.
