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.

"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. Selleris bills for outcomes — and structures the work to make that possible. Before any task, Selleris estimates three things: the business benefit it's expected to produce (in dollars or measurable KPIs), the cost to deliver it, and the projected ROI. The client approves work based on those numbers, not on a vague scope. Inside the engagement, tasks are prioritized by ROI — the ones that produce the most value per dollar go first. Tasks that don't justify their cost don't get built, even if they're on the original wishlist. After delivery, Selleris reports 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.
Selleris specializes 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. Bitrix24 offers all-in-one business collaboration at an accessible price point. Rather than selling dozens of platforms superficially, Selleris masters these three to give clients an honest recommendation based on what the business actually needs — not what earns the highest margin.
Selleris starts with the business — not with the software. During a structured discovery phase, Selleris maps the client's sales workflows, team structure, existing tech stack, integration needs, and growth plans. Those requirements are then matched 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 adding users. The client receives a transparent comparison, and the final choice is always theirs.
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. Selleris has 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. The client receives proactive recommendations — ranked by projected ROI — for what to build, automate, or optimize next. This turns CRM from a one-time project into a continuous compounding asset, with the highest-return next move always identified.
No, because of how the team and delivery process are structured. Two layers make this work. First, the 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 is being deployed — refined across 400+ delivered projects. Second, Selleris has dedicated teams certified in each platform: HubSpot specialists, Dynamics 365 consultants, and Bitrix24 developers do not cross over on core platform work. The integration layer is also standardized: all three platforms expose modern REST APIs, OAuth 2.0 authentication, and webhooks, so Selleris's Azure-based integration patterns (using Service Bus, Logic Apps, Functions, and Data Factory) work consistently across HubSpot, Dynamics 365, and Bitrix24. The result is specialist depth on the chosen platform plus a team that can give honest cross-platform advice because they actually work across all three every week.
Full cycle means Selleris handles 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. The client gets a single accountable partner from first conversation to production — and beyond.
Timeline depends on scope, complexity, and how much data needs to migrate. 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. Milestones and deliverables are defined upfront, so at every stage the client knows what has been delivered, what is in review, and what is next.
CRM implementation pricing depends on three factors: the scope of custom development, the number of system integrations, and the complexity of 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. Selleris provides 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, simplifying 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 — so the same integration architecture works for a US healthcare company with HIPAA requirements, a European company under GDPR, or a global business with both.
