What is Customer Relationship Management – and Why Is It Important?

Customer relationship management (CRM) is the way a business keeps track of every customer and prospect: who they are, every conversation you have had with them, what they have bought or asked for, and what needs to happen next. The term covers both the practice and the CRM software that makes it possible, a shared system that replaces scattered inboxes, spreadsheets and sticky notes.

This guide explains what CRM means, what a CRM system actually does day to day, the main types of CRM, and how to tell whether your business needs one.

Key points

• CRM stands for customer relationship management. It is both a business approach and the software that supports it.
• A CRM system stores contacts, conversations, deals and tasks in one place that the whole team can see.
• Its main job is to make sure no lead or customer is forgotten, and that everyone knows what happens next.
• There are three classic types: operational, analytical and collaborative. Most modern CRMs combine all three.
• If you are losing track of follow-ups, or customer details live in one person’s inbox, you have outgrown spreadsheets.

What does CRM stand for?

CRM stands for customer relationship management. The phrase is used in two ways:

• As a strategy: the way a business manages its relationships with prospects and customers, from the first enquiry through to repeat business.
• As software: a CRM system (or “a CRM”) is the tool that records those relationships and the work around them.

When people say “we need a CRM”, they almost always mean the software.

What does a CRM system do?

A CRM gives every customer and prospect a single record, and connects everything that happens with them to that record. Most CRM systems cover these jobs:

• Contact and company records: names, phone numbers, emails, addresses, notes and custom details such as job type or budget.
• Lead and pipeline tracking: where each prospect is in your sales process, from new enquiry to won or lost.
• Communication history: emails, calls, texts and meetings logged against the contact, so anyone on the team can pick up the conversation.
• Tasks and reminders: follow-ups assigned to a person with a due date, so nothing depends on memory.
• Marketing: email and SMS campaigns sent to segments of your contacts, with opens, clicks and replies recorded.
• Quotes, invoices and contracts: documents created from the customer record, so prices and details are not retyped.
• Reporting: how many leads came in, where they came from, how many converted and how long it took.

How does CRM work? A worked example

Imagine a small kitchen-fitting business using a CRM:

1. A homeowner fills in the enquiry form on the website. The CRM creates a lead automatically, tagged with the page and campaign they came from.
2. The lead is assigned to a team member, who gets a notification and a task: “Call within 24 hours”.
3. The call is made and logged, with notes on the size of the kitchen and the budget.
4. A quote is created from the lead record and emailed. The CRM records when it was sent and opened.
5. No reply after a week, so the CRM reminds the team member to follow up.
6. The customer accepts. The lead moves to won, the job becomes a project with tasks, and an invoice is raised from the same record.
7. Months later, the customer is added to an email campaign about a related service, and the owner can see exactly how much that customer has been worth.

Without a CRM, each of these steps lives somewhere different: the form in an inbox, notes on paper, the quote in a Word document, and the follow-up in someone’s head.

Why is CRM important?

• Leads stop slipping through the cracks. Every enquiry is recorded and every follow-up has an owner and a date.
• The whole team sees the same picture. If someone is off sick or leaves, their customer conversations do not go with them.
• Faster responses. Customers expect a quick reply. A CRM shows who is waiting and for how long.
• You learn what marketing works. When every lead records its source, you can see which campaigns produce customers, not just clicks.
• More repeat business. Purchase history and notes make it easy to contact the right customers at the right time.
• Less admin. Quotes, invoices and emails are created from data you already have, instead of being retyped.

The three types of CRM

Small businesses rarely need to choose between them. Most CRMs built for smaller teams, including Telagus, combine all three in one system.

CRM vs a spreadsheet

Many businesses start with a spreadsheet, and for a handful of customers that can work. These are the points where it usually breaks down:

What is a web-based CRM?

A web-based (or cloud) CRM runs in your browser instead of being installed on each computer. Anyone on your team with a login can use it from the office, from home or on a phone, and the provider handles hosting, updates and backups. You can give each person their own permissions, which is useful for freelancers and remote staff. Almost all modern CRMs for small businesses, Telagus included, are web-based.

Who uses a CRM?

• Sales teams track leads, calls and deals through the pipeline.
• Marketing teams send campaigns and see which ones produce customers.
• Customer service sees the full history before replying.
• Business owners get one view of the pipeline, revenue and team activity.

CRM is used in almost every industry, from trades and professional services to ecommerce, property, insurance and manufacturing. The core idea is the same everywhere: one record per customer, shared by everyone who deals with them.

How to choose a CRM

1. List what you do today. Write down how leads arrive, how you follow up, and where quotes, invoices and emails are created.
2. Decide what must be built in. If you call and text customers, look for calling and SMS inside the CRM rather than paid add-ons.
3. Check how pricing works. Per-user pricing gets expensive as you hire. Plan-based pricing with users included is easier to predict.
4. Try it with real data. Import a sample of your contacts and run a week of real follow-ups before you commit.
5. Check the support. Find out who will help you set it up, and how you reach them.

Frequently asked questions

What is CRM in simple terms?

CRM is a shared system for keeping track of your customers and prospects: their details, every conversation you have had with them, and what needs to happen next.

Is CRM a software or a strategy?

Both. Customer relationship management is the practice of managing customer relationships well, and CRM software is the tool most businesses use to do it.

What are the three types of CRM?

Operational CRM runs day-to-day sales, marketing and service. Analytical CRM turns customer data into reports and insight. Collaborative CRM shares customer information across teams. Most small-business CRMs combine all three.

What is an example of CRM?

A website enquiry automatically becomes a lead, is assigned to a salesperson with a follow-up task, receives a quote from the same record and, once won, becomes a project and an invoice, with every step logged in one place.

Does a small business need a CRM?

If customer details are spread across inboxes and spreadsheets, follow-ups are missed, or more than one person deals with customers, a CRM will usually save time and win back lost sales.

How much does a CRM cost?

Prices range from free plans to hundreds of pounds per user per month for enterprise systems. Telagus has a free plan, and its paid plans start at £340 a year for up to 2 users.
