Every growing business reaches the point where its customers live in many places at once: some in the ERP, some in a salesperson’s spreadsheet, conversations in individual inboxes, quotes in folders on the server. When a colleague leaves, half the history of their customers leaves too. That is what a CRM solves.
The question is which CRM. Off-the-shelf products cover many businesses. When the way you sell and serve is your own, a custom CRM can make the difference. This guide explains when it is worth it, what it is made of and how such a project is organised.
What a CRM is
CRM stands for customer relationship management. In practice it is a system that holds the full picture of every customer: contacts, company, conversations, quotes, orders, requests, documents. The team sees the same information, knows what has happened and what comes next, and management sees where sales stand without asking for reports.
Off-the-shelf or custom?
Ready-made CRMs start fast, have many features and are updated by the vendor. They also have limits. They make you work their way, charge per user every month and, when you need something specific, customisation is expensive or impossible. A custom CRM is designed around your processes. It has only what you need, with the names and steps your team already uses, and grows with the business.
| Off-the-shelf CRM | Custom CRM | |
|---|---|---|
| Start | Fast | Needs analysis and development |
| Fit with your processes | You adapt | The system adapts |
| Cost | Monthly fee per user | Initial investment and maintenance |
| Integrations | Whatever the vendor offers | Whatever you need |
| Data | On the vendor’s servers | Wherever you decide |
When a custom CRM is worth it
- Your sales process has steps a standard product cannot hold, such as several approval stages or complex quotes.
- You want to take the whole business workflow digital, not just sales: service, contracts, projects, partners.
- You need a tight connection to your ERP and other existing systems.
- You have many users and the monthly fee of a ready-made CRM adds up over the years.
- You want customer data to stay under your own control.
If your business sells in a simple, standard way, an off-the-shelf CRM is usually the right choice, and we will tell you so.
The modules of a CRM
- Contacts and companies: all details and history on one record.
- Sales opportunities: stages from first interest to signature, with value and probability.
- Quotes: built from your price list, with approvals, sending and tracking.
- Tasks and reminders: who does what and when, so no customer is left waiting.
- Service requests: logging, assignment, response times, history.
- Contracts and documents: files organised by customer, with expiry dates and renewals.
- Partners: a portal for resellers, partners or external teams with limited access.
- Reports and indicators: sales by salesperson, region, product and channel, in real time.
Connecting to your other systems
- ERP: customers, items, prices, balances and orders stay in sync. See our ERP, CRM and SAP services.
- Website and forms: every enquiry becomes a contact and a task automatically.
- Email and calendar: conversations are logged on the customer record.
- Marketing: you know which campaign brought each customer and what it was worth. More in our guide to digital marketing.
How a project runs
- Analysis. We talk with the people who will use it and map how they work today.
- Design. Screens, roles, permissions, integrations. You see and approve them before code is written.
- First version. We start with the modules that bring the most benefit, so the team uses it quickly.
- Data migration. We clean and move customers and history from existing files and systems.
- Training and handover. On your own data.
- Growth. Based on real use, we add modules and improvements.
What drives cost and time
- The number of modules and the complexity of the processes.
- Integrations with ERP and other systems.
- The volume and condition of the data to be migrated.
- Roles and access rights.
- Whether a mobile app or an external portal is needed.
After the analysis you receive a written proposal with scope, cost and timeline. Ownership of code and data is set out in the contract.
Costly mistakes
- Everything on day one. A CRM with a hundred features nobody asked for does not get used.
- Designing without the users. If salespeople do not find it useful, they go back to spreadsheets.
- Dirty data. Duplicates and incomplete records damage trust in the new system.
- No integration. A CRM cut off from the ERP doubles the work instead of reducing it.
