Custom CRM Development Services
Our team provides custom CRM development services for companies that need a new CRM, want to modernize an existing system, or add CRM functionality to another product. UITOP combines UX-first design with CRM software development, integrations, data migration, and post-launch support.




CRM Systems Built Around
Your Business Processes
Match CRM workflows to how your teams actually work
Sales, account management, support, and operations often follow different processes even when they work with the same customer. We map these workflows first, including roles, permissions, deal stages, approvals, and handoffs between teams. The CRM is then built based on this logic.

Connect customer data across teams and systems
Customer information is typically split between the CRM, email, support tools, billing software, spreadsheets, and other internal systems. So, our team connects the relevant sources and defines how records, communication history, deals, and activities should move between them. This helps work with the same information.
Expand CRM functionality as your operations grow
A CRM rarely stays exactly as it was at launch. New teams may need access, approval flows can become more complex, and additional reports, modules, or integrations may be required. We structure the system so these changes can be introduced as the business develops, while taking the existing architecture and dependencies into account.

Custom CRM Development Case Studies

Slabstack: redesigning a CRM for heavy materials producers
Slabstack created a developer version of their software for concrete and asphalt producers, but users lost time on complex navigation.In 3 months, the UITOP team reorganized the product architecture and redesigned 156+ screens.
The new interface simplified project management, reporting, customer data, and built-in email. Launched in 4 months, this increased demo-to-user conversion by 87% and achieved a usability score of 97.

Aimiable: redesigning an AI workflow platform for customer service teams
Aimiable helps customer service teams handle scheduling and workload with AI, but its interface became overloaded as features expanded. Over 4 months, UITOP redesigned 185 screens, improving forecasting clarity, workload redistribution, and building a component library.

Frequently asked questions
What CRM development services does UITOP provide?
UITOP works on CRM projects from early product research through release and later updates. The scope depends on what your company already uses and how much of the new system should be built. A new CRM often starts with process discovery and UX/UI. When an existing platform is being replaced, integration and migration usually affect decisions much earlier. We also cover analytics, mobile access, testing, and support after launch when necessary.
Can UITOP develop a custom CRM from scratch?
Yes. When there is no existing CRM to build on, we first study how your team handles customer work today and what information each role needs. This gives us enough context to decide what to provide in the first release. If the CRM depends on external systems, these connections are considered during planning because they often influence both the interface and the underlying data model.
Can you modernize or extend an existing CRM system?
Yes. We can modernize an existing CRM when the system still contains useful functionality, but parts of it have become difficult to use or maintain. In some projects, the main issue is an outdated interface. In others, the codebase or integrations make further development slower than it should be. We review the current CRM first, then decide what is worth keeping and what is worth optimizing.
Can you add CRM functionality to an ERP or another business platform?
Yes, our team can develop CRM functionality within the platform you already use. Before defining this module, we review its architecture and how customer data is stored. Existing roles matter here as well, since CRM permissions should typically work with access rules that are already present elsewhere in the product.
Can a custom CRM integrate with our existing business software?
In many cases, yes. We first need to understand how the other system allows data to be exchanged and what technical limits apply. If your CRM receives customer information from another platform, the project should have a defined rule for where this record is maintained. We also determine how frequently the systems should exchange updates based on the way your team uses the information.
Can you migrate data from our current CRM?
Yes. Before transferring records, UITOP examines how the current CRM stores them and how the structure differs from the new system. Existing data may contain duplicates or values that no longer match the new CRM rules, so these records call for initial attention. We normally test the migration first and let your team review the imported information.
How long does custom CRM development usually take?
There is no fixed duration. Timing depends on what must be ready for the first release and how much existing infrastructure the new system has to work with. We estimate delivery after the main workflows and technical requirements have been reviewed and discuss whether staged releases suit your team.
How do you approach CRM security and access control?
CRM access control usually comes down to fairly specific questions: who can open a record, who can edit it, and which actions require a different level of permission. We define these rules while the CRM workflows are being designed, because they affect both the interface and backend logic. If your company has formal compliance requirements, our team also reviews them so they are taken into account in the technical scope from the start.
