Custom CRM Development

CRM solutions built from scratch for companies that need full control without Microsoft licensing: pipeline, customer service, field operations and reporting on a stack you own.

Custom CRM development with Solzet means you own what you pay for: an IP assignment clause in the contract, the source repository in your own GitHub or Azure DevOps from the first day, infrastructure in your own cloud subscription, and documentation, runbooks and deployment pipelines handed over. Our senior consultants and full-stack developers in Yerevan build on React, Next.js, TypeScript, Node.js, .NET and PostgreSQL, with no per-user licensing. Custom CRM is not a competitor to Dynamics 365; it is the alternative when licensing or control rules Microsoft out. We recommend the right solution: Dynamics 365 (Customer Engagement, Business Central or Finance and Operations), Power Platform, or a custom-built CRM.

Why do companies choose a custom CRM instead of Dynamics 365?

Most organizations that come to us for a custom CRM have already looked at Dynamics 365, Salesforce or HubSpot and found one of four blockers. None of them means the packaged platforms are bad products; they mean the licensing model or the platform boundary does not fit this particular business.

When none of these apply, we will usually recommend Dynamics 365 or Power Platform instead, because configuring a mature platform is faster than building one. When one or more of them do apply, a custom CRM gives you the same business capabilities without the constraint.

  • Licensing that does not scale with the business. Per-user subscriptions compound as headcount grows, and they hit hardest when many people need light access, such as field staff, branch employees or seasonal teams.
  • Full ownership and no vendor lock-in. You own the source code, the database and the roadmap, and nobody can change the price or retire a feature you depend on.
  • Data sovereignty and hosting rules. Government bodies and regulated organizations sometimes must host on their own infrastructure or in-country, which a public cloud CRM cannot always satisfy.
  • A process no packaged CRM expresses well. When the core of the business is a workflow that would need heavy customization on any platform, building it directly is often simpler to run and cheaper to change.

What can a custom CRM do?

Everything a business expects from a CRM, designed around your process rather than around a vendor's data model. We scope a first release around the process that matters most, then extend it in phases, so people use the system early and shape what comes next.

  • Pipeline and opportunity management with stages, forecasts, quotes and activity history.
  • Customer service and case management with queues, SLAs, escalation rules and a knowledge base.
  • Field operations: work orders, scheduling, dispatch and a mobile interface for technicians.
  • Customer and partner portals where external users submit requests and track progress.
  • Reporting and dashboards over live data, plus exports your analysts can use.
  • Integrations with email, telephony, accounting and billing systems, websites and existing line-of-business applications through documented APIs.
  • Role-based security, audit trails and multilingual interfaces, including Armenian, Russian and English.

Which technologies do we build custom CRMs with?

We use mainstream, well-supported open technologies so any competent team can maintain the system after us, and so there is no licence to pay for the stack itself.

LayerTechnologyWhy it matters
InterfaceReact, Next.js and TypeScriptFast, accessible web interfaces that work on desktop and mobile, with typed code that stays maintainable as the system grows.
Application and APINode.js (TypeScript) or .NETBusiness logic and integrations behind a documented API. We choose .NET where your organization already standardizes on it.
DatabasePostgreSQLA proven open-source relational database with strong data integrity, full-text search and no licence cost.
IdentitySingle sign-on over OpenID ConnectUsers sign in with the accounts they already have, such as Microsoft Entra ID or Google Workspace, with role-based permissions inside the CRM.
HostingYour cloud or your own serversAzure, AWS, a local data centre or on-premises infrastructure, chosen to meet your security and data residency requirements.

What do you own, and what do you receive at handover?

Ownership is the reason most buyers choose a custom CRM, so it should be concrete and written down, not implied. With Solzet it means six things, all agreed in the contract before the first sprint and visible to you from the first day rather than delivered in a box at the end.

The practical test is simple: if Solzet disappeared tomorrow, could another competent team pick up the system from what you already hold? With the items below in place, the answer is yes. That is also why the comparison in our guide on when building a CRM beats licensing one treats ownership as a property of the contract, not of the technology.

  • An IP assignment clause: the intellectual property in the code, data model, designs and documentation written for your project is assigned to you, with assignment taking effect as each milestone is paid rather than only at the very end.
  • The source repository in your own GitHub organization or Azure DevOps project from day one, with our developers invited as members, so every commit lands in an account you control and can revoke access to.
  • Infrastructure in your own cloud subscription (Azure, AWS or your data centre), created under your account and defined as infrastructure as code, so you hold the billing relationship and the admin rights.
  • Documentation and runbooks: the architecture, data model, API reference, environment setup, deployment steps, backup and restore, and what to do when something fails at night.
  • The CI/CD pipeline: build, test and deployment pipelines that live in your repository and run in your account, so releasing a change never depends on a laptop at Solzet.
  • A licence, not an assignment, for anything pre-existing: if a project uses a component that existed before it, such as an open-source library under its own licence or a reusable module brought in from outside the project, you receive a perpetual, irrevocable, royalty-free licence to use, modify and run it, and the contract lists each such component by name.

Which clauses should a buyer insist on in a custom CRM development contract?

Whichever firm you hire, check the contract against this list before you sign. Each line closes a gap we have seen cause disputes in software projects generally, and none of them should be controversial for a firm that intends you to own the result.

  • IP assignment of all project-specific work to you, effective on payment of each milestone.
  • A named list of pre-existing and third-party components, with the licence that applies to each, and no component that would restrict your use or resale of the system.
  • Source code and infrastructure held in accounts you own from the start, written as an obligation, not a courtesy.
  • Documentation and runbooks defined as deliverables with acceptance criteria, not as best effort.
  • Deployment pipelines and environment definitions handed over as part of the code, so the system can be rebuilt from your repository alone.
  • Data ownership and data protection terms: your data stays yours, is processed only for the project, and is exported in an open format on request.
  • Exit and handover terms: a defined handover period, knowledge transfer sessions for your team or a new supplier, and no fee for leaving.
  • Confidentiality that protects your business, and a non-solicitation clause that does not stop you hiring your own maintainers.

Looking for a custom CRM development company in Eastern Europe?

Solzet is headquartered in Yerevan, Armenia, between Europe and the Middle East, and builds custom CRMs on React, Next.js, TypeScript, Node.js, .NET and PostgreSQL with full IP transfer and no per-user licensing. Yerevan is on UTC+4, so our working day overlaps most of the European business day. The work is done by our own senior consultants and full-stack developers, and the same people support the system after go-live.

How does a custom CRM project run?

The same way our Dynamics 365 projects run, which is deliberate: discovery first, then short iterations you can see and test. Commercially we work fixed price per milestone where scope is clear, or time and materials against a prioritized backlog, and we quote after a scoping conversation rather than before one.

  • Discovery: map the processes, users, data and integrations, and confirm that a custom build is genuinely the right answer rather than a platform you could configure.
  • Design: the data model, the screens for each role, the security model and the integration contracts, reviewed with the people who will use them.
  • Iterative build in two-week sprints, each ending with a working demo in a test environment.
  • Data migration from spreadsheets, legacy systems or another CRM, with reconciliation reports so nothing is lost silently.
  • Go-live, training and hypercare, followed by ongoing support and development from the same engineers.

Custom CRM or Dynamics 365: which costs less over time?

It depends on the shape of your organization, so we compare total cost of ownership over several years rather than the first invoice. Dynamics 365 is a recurring per-user licence plus implementation; a custom CRM is a build plus hosting and support with no per-user licence. We do not publish prices because scope drives both, but the factors below decide which way the comparison falls.

FactorDynamics 365 tends to win whenCustom CRM tends to win when
UsersA modest number of full users work in the system all day.Many users need light or occasional access, so per-user licensing multiplies.
ProcessYour processes are close to standard sales, service and field service patterns.Your core workflow is specific enough that any platform would need heavy customization.
EcosystemYou run Microsoft 365 and Teams and want Copilot and the Microsoft roadmap.You want independence from any single vendor's roadmap and pricing.
Time to valueYou need standard capabilities quickly and can adapt to the platform.You can phase delivery and want the system shaped exactly to the business.
HostingMicrosoft cloud regions satisfy your data residency requirements.You must host in-country or on your own infrastructure.

Can you move from a custom CRM to Dynamics 365 later?

Yes, and we design for that possibility. A custom CRM we build has a documented data model and API, so migrating its data to Dynamics 365 and Dataverse later is a planned project rather than an archaeology exercise. Because we deliver both, we can also run the migration ourselves. The reverse is true too: organizations that have outgrown a Dynamics 365 implementation that never fitted them can move to a custom system with their history intact.

If you are weighing CRM options for the Armenian market specifically, our CRM in Armenia guide compares the options available locally, and public sector buyers should read our page on government CRM solutions.

What do buyers ask us?

How much does a custom CRM cost compared to Dynamics 365?

It depends on scope, and we do not publish prices. The fair comparison is total cost over several years. Dynamics 365 costs a recurring per-user licence plus implementation and support. A custom CRM costs a one-time build, then hosting and ongoing support, with no per-user licence. With a modest number of users and standard processes Dynamics 365 is often cheaper; with many users, light usage or a very specific process a custom build often is. We model both options after a scoping conversation and quote per milestone.

When should I choose custom CRM over Dynamics 365?

Use a simple rule. If you can afford the licensing and want the Microsoft ecosystem, choose Dynamics 365. If you need full control of the platform and zero per-user licensing, choose a custom CRM. If you are not sure, a short discovery decides it by weighing licensing budget, process complexity, integrations, hosting requirements and long-term ownership. We deliver both, so the recommendation follows your situation rather than the product we sell.

Can you migrate from a custom CRM to Dynamics 365 later?

Yes. The custom CRMs we build have a documented data model and API, which makes a later migration to Dynamics 365 and Dataverse a planned, predictable project. Because we deliver Dynamics 365 as well, the same team can map the data, migrate the history and rebuild the business rules on the Microsoft platform when the time is right.

What technologies do you use for custom CRM development?

React, Next.js and TypeScript for the interface, Node.js or .NET for the application layer and APIs, and PostgreSQL for the database, with single sign-on over OpenID Connect and hosting on Azure, AWS, a local data centre or your own servers. These are mainstream, well-supported technologies, so the system is maintainable by any competent team and carries no licence cost for the stack itself.

Do you provide ongoing support for custom-built CRMs?

Yes. After go-live we support and extend the system with the same engineers who built it, either as a monthly allocation of hours or as scoped enhancement work. Support covers monitoring, security updates, bug fixes, new features as your processes change, and help for your own team if you decide to take development in-house.

Who owns the source code and the data of a custom CRM?

You do. Ownership of the source code, the database, the documentation and the deployment configuration is written into the contract before work starts, through an IP assignment clause for everything written for your project. The repository sits in your own GitHub or Azure DevOps from day one and the system runs in your own cloud subscription or on your infrastructure, so you are never dependent on us to access your own code or data.

What should a custom CRM development contract say about IP transfer?

It should assign the intellectual property in all project-specific work to you on payment of each milestone, list every pre-existing or third-party component with the licence that applies to it, require the source code and infrastructure to sit in accounts you own from the start, define documentation, runbooks and pipelines as deliverables, and set out exit and handover terms with no fee for leaving.

Is Solzet a custom CRM development company in Eastern Europe?

Solzet is headquartered in Yerevan, Armenia, and builds custom CRMs for clients in Europe, the US and Armenia on React, Next.js, TypeScript, Node.js, .NET and PostgreSQL, with full IP transfer and no per-user licensing. Yerevan is on UTC+4, so our working day overlaps most of the European business day.

Is a custom CRM secure enough for government and regulated organizations?

It can be designed to meet strict requirements, and for some public sector bodies it is the only option that satisfies in-country hosting rules. We build role-based access control, audit trails, encryption in transit and at rest, single sign-on and data retention rules into the design, and we support your security review and penetration testing before go-live.

Is a custom CRM the right fit for you?

Describe your process and what you use today. A senior consultant replies within one business day and tells you honestly whether a custom build, Dynamics 365, or Power Platform fits best.
