Most CRM agencies sell a single platform. That biases every recommendation they make, because the answer is decided before the question is asked.
Selleris is certified across three fundamentally different CRM categories, so the platform recommendation is an output of the ROI model — not the starting assumption.
Best fit when marketing-and-sales alignment is the priority, you want fast time-to-value, and inbound demand generation is a core part of the motion.
Best fit when you need enterprise-grade processes, deep ERP and Microsoft 365 integration, complex sales operations, and full custom development on Microsoft Azure.
Best fit when you need an all-in-one operational platform — CRM, project management, internal communications, and automation in one system — at mid-market economics.
"Selleris is our partner for Bitrix24 hosting and development, and we are very happy to have chosen them. They are nice people, and they know what they are doing, with structured approaches, great communication, and technical expertise."

"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.
CRM implementation cost depends on three factors: scope of custom development, number of system integrations, and complexity of data migration.
At Selleris, Bitrix24 implementations start at $5,000, with most projects landing between $8,000 and $25,000.
HubSpot implementations start at $12,000 for focused Sales Hub or Marketing Hub deployments and reach $60,000+ for multi-hub RevOps projects.
Microsoft Dynamics 365 implementations start at $25,000 for standard rollouts and reach $150,000+ for enterprise deployments with Azure integrations and ERP connectivity.
Every project receives a detailed fixed-price estimate after the discovery phase — no hourly surprises, no scope creep billed mid-project.
A full Selleris CRM implementation runs through five phases: Discovery and ROI Modeling (1–3 weeks), Solution Design (2–4 weeks), Build and Integrate (4–12 weeks depending on scope), Adoption and Enablement (2–4 weeks), and Optimization and Growth (ongoing). Total time-to-launch typically ranges from 9 weeks for a focused Bitrix24 or HubSpot rollout to 6 months for an enterprise Dynamics 365 deployment with Azure-based custom development and ERP integration.
Hourly billing makes effort the visible metric, so every change request becomes a budget renegotiation and every invoice becomes a discussion of timesheets rather than business value. Selleris uses fixed-price implementation at the task level: each task is sized for a single sprint, priced once at estimate, and approved on its expected ROI before work begins. Estimation variance is absorbed by Selleris, not passed to the client. New requirements don't trigger budget escalations — they enter the same intake-and-approval loop as new tasks with their own ROI.
There is no universally best CRM. The right platform is the one with the highest ROI for a specific business. HubSpot is the best fit when marketing-and-sales alignment is the priority, time-to-value matters, and inbound demand generation is core to the motion. Microsoft Dynamics 365 fits enterprise-grade processes, deep ERP and Microsoft 365 integration, complex sales operations, and full custom development on Microsoft Azure. Bitrix24 fits teams that need an all-in-one operational platform — CRM, project management, internal communication, and automation — at mid-market economics. Selleris is certified across all three categories, so the platform recommendation is an output of the ROI model, not a starting assumption.
A Selleris CRM implementation includes business process discovery, ROI modeling, platform selection, solution architecture, data migration, system configuration, custom development on Microsoft Azure where required, integrations with ERP and operational systems, role-based user training, change management, adoption tracking, and ongoing post-launch optimization. Each piece of work is scoped as a sprint-sized task with its own expected ROI and a fixed price agreed before execution.
Selleris models ROI at two levels. At project level, the discovery phase produces a financial model tied to the business KPIs the implementation commits to moving — pipeline conversion, sales cycle length, retention, operational cost reduction. At task level, every individual task in the implementation has its own expected benefit in money, calculated at intake and used as the basis for client approval. After launch, the same task-level ROI loop continues on every improvement, with monthly delivery reports summarizing investments made and value delivered.
Yes. Data migration is a standard part of every Selleris CRM implementation and is one of the three factors driving project pricing alongside custom development scope and integration count. Migration covers contacts, accounts, opportunities, historical activity, custom objects, attachments, and audit history, with data cleansing and deduplication performed before load. Migration scope and complexity are assessed during the discovery phase and priced as part of the fixed-price estimate.
Yes. When out-of-the-box CRM functionality cannot meet a business requirement, Selleris builds custom development on Microsoft Azure — including custom portals, AI agents, applications, and integrations between the CRM and ERP, marketing, finance, or operational systems. Custom development is scoped, estimated, and approved task-by-task using the same ROI loop that governs configuration work.
