Why a custom CRM?

Your process, not the platform’s limits

Off-the-shelf solutions force you to change how you work. A custom CRM is built around your sales and service process, not the other way around.

Automation that saves time

Reminders, status changes, emails and tasks trigger automatically. The sales team focuses on clients, not data entry.

Full client history in one place

Contacts, deals, communication, contracts and documents in a single view. No request gets lost and handovers between colleagues are smooth.

What a custom CRM covers

  • Contact and organisation management

    A structured client base with roles, relationships and segments. Search and filters that find the right contact in seconds.

  • Sales pipeline and deals

    A visual pipeline with stages that match your sales process. Each deal has its history, tasks and next steps.

  • Automation and workflows

    Automated reminders, status changes, email sending and task creation. Rules that work on your behalf.

  • Reports and analytics

    Sales forecasts, conversion rates and team performance in real time. Dashboards that give managers an overview without opening a spreadsheet.

  • Rights and contract management

    Licence, copyright and contract tracking with deadlines, territories and terms. A specialised solution for media and publishing.

  • Integrations with your systems

    Email, accounting, online store, marketing automation and ERP. The CRM becomes the central data source for your business.

CRM solutions in practice

We have built custom CRM systems for a range of organisations. For Bonnier Rights Finland we created a rights management system where the publisher tracks copyright licences, territories and contract terms. For EALA we built a client management solution that supports their daily work with members and partners.

Every CRM is built around the specific organisation’s processes – not a generic template, but a tool that fits that particular team.

Frequently asked questions

  • Why not use an off-the-shelf CRM like HubSpot or Salesforce?

    Ready-made solutions work well for standard sales processes. When your business has specifics – such as rights management, custom workflows or complex integrations – a custom CRM is more cost-effective in the long run because you don’t pay for features you don’t use and you get exactly what you need.

  • How long does CRM development take?

    A first working version with core features is typically ready in 2–4 months. A system with broader functionality may take longer. We provide an accurate timeline after analysis.

  • Can you migrate existing data into the new CRM?

    Yes. During migration we transfer contacts, deals, communication history and documents. We clean and validate data before the transfer.

  • Does the CRM integrate with email and calendar?

    Yes. Typical integrations include email (Gmail, Outlook), calendar, accounting software, online store and marketing automation.

  • How is data security ensured?

    We are ISO 27001 certified. The CRM includes role-based access, data encryption and an audit log. Personal data processing follows GDPR requirements.
