CRM stands for Customer Relationship Management. A CRM system helps a business organize leads, customer information, communication, sales opportunities, quotations, activities, and follow-up work in one place.However, modern customer relationship management goes far beyond storing names, telephone numbers, and email addresses. A useful CRM should help employees understand each customer, manage opportunities, coordinate responsibilities, improve service, and turn customer information into measurable business results.CRM creates even more value when it is connected to an ERP system. This connection allows customer information to continue into quotations, orders, inventory, purchasing, production, delivery, invoicing, service, and finance without entering the same data again.
Quick answer: CRM manages the relationship with a potential or existing customer. ERP manages the wider business processes needed to fulfil the customer’s requirements. A connected CRM and ERP create one continuous process from the first enquiry to payment, service, and repeat business.

What Does a CRM System Do?

A CRM system creates a shared record of the relationship between a company and its potential or existing customers. Authorized employees can use this record to understand what has happened, what is happening now, and what should happen next.A complete customer record may contain:
  • Company and contact information
  • Telephone calls, emails, meetings, and notes
  • Lead sources and marketing campaigns
  • Sales opportunities and pipeline stages
  • Tasks, activities, and follow-up dates
  • Products and services of interest
  • Quotations, proposals, and contracts
  • Customer-specific prices and commercial terms
  • Orders, deliveries, invoices, and payments
  • Projects and service requests
  • Complaints, warranties, and support history
  • Documents, approvals, and communication preferences
Without a CRM, this information is often spread across spreadsheets, email inboxes, notebooks, messaging applications, and individual devices. Employees may each know one part of the customer story, but nobody can see the complete relationship.A CRM replaces these disconnected fragments with one controlled source of customer information.

Why Do Businesses Need CRM?

Businesses do not always lose sales because their products are unsuitable. Opportunities are also lost when follow-ups are late, responsibilities are unclear, quotations are inconsistent, or customer information cannot be found.
Without structured CRMWith structured CRM
Leads remain in personal spreadsheets or inboxes.Every lead has a source, owner, status, and next action.
Follow-up depends on memory.Tasks, reminders, and deadlines make the next step visible.
Several departments create duplicate customer records.Teams work with one controlled customer profile.
Management receives unreliable pipeline reports.Opportunities are organized by stage, value, probability, and date.
Customer knowledge disappears when an employee leaves.Communication and commercial history remain with the company.
Sales cannot see stock, delivery, or invoice status.Connected CRM and ERP provide operational context.
The main purpose of CRM is therefore not to create more administration. It is to give employees the information, structure, and reminders they need to manage customer relationships consistently.

How Does CRM Work?

CRM follows the customer journey from the first contact to a completed sale and the relationship that continues afterward.
CRM stageWhat happensImportant information
Lead captureA potential customer enters the system.Source, contact details, interest, responsible employee
QualificationThe sales team checks whether the enquiry is a realistic opportunity.Need, budget, timing, authority, expected value
OpportunityThe potential sale enters the pipeline.Stage, probability, closing date, next action
QuotationThe company prepares a commercial offer.Products, services, prices, discounts, terms
DecisionThe opportunity is won, lost, delayed, or returned for revision.Decision, reason, competitor, follow-up
Order and fulfilmentThe accepted offer becomes an operational commitment.Availability, production, purchasing, delivery
Service and retentionThe company supports the customer and develops the relationship.Service history, complaints, renewals, repeat opportunities
Each stage should have a clear owner and a required next action. This prevents leads from becoming inactive simply because nobody knows who should respond.

What Is the Difference Between a Lead, Contact, Account, and Opportunity?

CRM terminology can be confusing because different systems use slightly different words. The following definitions cover the most common meanings.
CRM termSimple definitionExample
LeadA person or company that may be interested in buying.A website visitor requests information.
ContactAn individual person recorded in the system.A purchasing manager working for a customer.
Account or companyThe organization connected to one or more contacts.A manufacturing company with several contact persons.
OpportunityA qualified potential sale.The customer is considering a production machine worth EUR 40,000.
ActivityAn interaction or planned action connected to the relationship.A call, meeting, demonstration, email, or site visit.
PipelineThe structured view of all active sales opportunities.Opportunities grouped by qualification, proposal, negotiation, and decision.

What Are the Main Benefits of CRM?

1. One Complete Customer View

A CRM brings customer information into one controlled profile. Employees can see communication, opportunities, quotations, orders, service cases, and open activities without searching through several applications.This helps the customer too. They do not need to explain the same issue repeatedly whenever they speak with a different department.

2. Faster and More Consistent Follow-Up

Every lead and opportunity should have a responsible employee, a status, and a next action. CRM reminders help sales teams respond on time and prevent important opportunities from being forgotten.Managers can also identify leads that have not been contacted or opportunities that have remained in one stage for too long.

3. A More Reliable Sales Pipeline

A CRM pipeline shows the commercial work currently in progress. It should make it possible to answer questions such as:
  • How much potential revenue is open?
  • Which opportunities may close this month?
  • Which opportunities have become inactive?
  • Which sales stages create delays?
  • Why are opportunities being lost?
  • How long does the average sales cycle take?
  • How accurate is the sales forecast?
A pipeline is only reliable when users update it consistently. Old opportunities with unrealistic values will create a misleading forecast.

4. Better Sales Prioritization

Not every opportunity deserves the same amount of attention. Sales teams can use the expected value, probability, closing date, strategic importance, customer history, and required effort to decide what to work on first.This does not mean that software should make every commercial decision. CRM gives the salesperson better information so they can make a more informed choice.

5. Less Administrative Work

Salespeople should spend more time understanding customers and less time copying information between systems.CRM can reduce routine work through:
  • Follow-up reminders
  • Reusable quotation templates
  • Automatic task creation
  • Standard document generation
  • Approval workflows
  • Customer-specific pricing
  • Contract-renewal reminders
  • Pipeline dashboards

6. Better Cooperation Between Sales and Marketing

Marketing can record where a lead came from, while sales can show whether the lead became a qualified opportunity, quotation, order, and profitable customer.This creates a much better measure of campaign performance. The company can evaluate business results instead of counting only clicks, forms, or imported contacts.

7. Better Customer Service

Customer service improves when employees can see the customer’s history before responding.They may need to know what was ordered, what was delivered, which price was agreed, whether an invoice is open, which warranty applies, and what was promised during an earlier conversation.A connected system gives the employee this context and helps the company respond as one coordinated organization.

8. Stronger Customer Retention

CRM can help identify early signs that a relationship needs attention. These signs may include falling order frequency, lower order value, unresolved complaints, repeated service problems, an expiring contract, or a customer who has not been contacted recently.Retention then becomes a managed activity rather than a reaction after the customer has already left.

9. Better Data Ownership

Customer information belongs to the business, not to one employee’s email account or spreadsheet.Central customer records protect the company when employees change roles or leave. Contact history, price agreements, documents, commitments, and opportunity status remain available according to the company’s access rules.

10. Better Reporting and Decisions

CRM reports can help managers analyze:
  • Lead response time
  • Lead-to-opportunity conversion
  • Opportunity-to-order conversion
  • Pipeline value by stage
  • Weighted sales forecasts
  • Sales-cycle duration
  • Won and lost opportunities
  • Reasons for lost sales
  • Revenue by customer or product
  • Repeat-purchase behavior
  • Customer profitability

CRM Versus ERP: What Is the Difference?

CRM manages customer relationships and sales activity. ERP manages the wider operational and financial processes of the business.
AreaCRMERP
Main purposeManage leads, customers, communication, and opportunitiesManage operations, resources, transactions, and financial results
Typical usersSales, marketing, account management, customer serviceSales, purchasing, warehouse, production, service, projects, HR, and finance
Typical recordsLeads, contacts, activities, opportunities, campaignsOrders, stock, purchase orders, work orders, invoices, payments
Main resultBetter customer engagement and sales managementConnected execution and financial control
A business may use CRM without ERP, especially when it only needs contact and pipeline management. However, this can create a gap between what sales promises and what the company can actually deliver.For example, a standalone CRM may show that a quotation was accepted, but it may not show whether the product is available, whether materials must be purchased, whether production has capacity, whether delivery is late, or whether the customer has paid.A connected CRM and ERP close this gap.

How Does CRM Work Inside an ERP System?

CRM inside an ERP system connects the customer-facing process with the operational work that follows.A connected customer journey may look like this:
  1. A website enquiry creates a lead.
  2. The lead is assigned and qualified.
  3. A qualified lead becomes an opportunity.
  4. The salesperson prepares a quotation using approved products, prices, and terms.
  5. The accepted quotation becomes an order.
  6. The system checks stock and expected supply.
  7. Missing items may create purchasing or production requirements.
  8. The warehouse prepares the order for delivery.
  9. Finance creates the invoice and records payment.
  10. Service or support activities remain connected to the same customer.
The customer record therefore becomes more than a sales profile. It connects customer expectations with the work required to fulfil them.

What Should a Good CRM System Include?

The right CRM depends on the business, but most organizations should evaluate the following capabilities:
CapabilityWhy it matters
Central customer recordsCreates one reliable source of customer information.
Lead managementRecords lead sources, ownership, status, and qualification.
Opportunity pipelineMakes potential sales and next actions visible.
Tasks and activitiesSupports timely and accountable follow-up.
Quotation managementConnects opportunities with approved products, prices, and terms.
Dashboards and forecastingHelps managers understand pipeline health and expected revenue.
Workflow automationReduces repetitive administration and highlights exceptions.
Role-based permissionsProtects sensitive customer and commercial information.
Mobile accessAllows employees to update information while away from the office.
ERP integrationConnects customer activity with orders, stock, delivery, service, and finance.

How to Choose the Right CRM

Do not choose CRM software only by comparing feature lists. Test how the system supports your real customer journey.During a demonstration, ask the provider to show:
  • How a new enquiry enters the system
  • How the lead is assigned and qualified
  • How activities and follow-up dates are recorded
  • How the lead becomes an opportunity
  • How a quotation is created
  • How prices and discounts are controlled
  • How an accepted quotation becomes an order
  • How sales checks stock or production capacity
  • How delivery and invoice status return to the customer record
  • How management measures conversion and forecast accuracy
Bring one real customer scenario into the demonstration. A realistic process reveals more than a polished presentation using perfect sample data.

How to Implement CRM Successfully

Installing CRM software does not automatically improve customer relationships. The company must define its process, prepare its data, train employees, and measure adoption.

Step 1: Define the Customer and Sales Process

Agree how leads enter the company, who qualifies them, when they become opportunities, which pipeline stages are required, and what must happen after a sale.

Step 2: Assign Ownership

Every lead, opportunity, customer, and follow-up activity should have a responsible employee. Shared responsibility often becomes no responsibility.

Step 3: Clean Customer Data

Remove duplicate companies and contacts. Correct invalid addresses, outdated contact persons, inconsistent company names, and unclear opportunity statuses before migration.

Step 4: Configure Roles and Permissions

Employees should see the information needed for their work. Sensitive financial, contractual, or personal information should remain limited to authorized roles.

Step 5: Build a Realistic Pipeline

Pipeline stages should match the company’s real sales process. Each stage needs a clear definition, required information, responsible role, and expected next action.

Step 6: Add Useful Automation

Begin with practical automation such as follow-up reminders, discount approvals, contract-renewal tasks, and alerts for inactive opportunities. Too much automation at the beginning can make the process harder to understand.

Step 7: Create Role-Based Dashboards

Salespeople need personal activities and opportunities. Sales managers need team performance and forecast accuracy. Senior management needs revenue, margin, customer profitability, and strategic account information.

Step 8: Train Employees on Real Work

CRM training should explain more than which buttons to click. Employees need to understand why information is recorded, how stages are defined, and how their updates affect other teams.

Step 9: Review and Improve

CRM should evolve with the business. Review adoption, data completeness, overdue activities, response time, conversion, forecast quality, and process bottlenecks regularly.

Which CRM Metrics Should a Business Track?

CRM metrics should help management understand both activity and business results.
MetricWhat it measures
Lead response timeHow quickly the company responds to a new enquiry
Lead conversion rateHow many leads become qualified opportunities
Win rateHow many opportunities become confirmed business
Sales-cycle durationHow long it takes to move from enquiry to decision
Pipeline coverageWhether open opportunities are sufficient to support the sales target
Forecast accuracyHow closely predicted sales match actual results
Average order valueThe typical value of completed customer orders
Repeat-purchase rateHow often existing customers buy again
Customer profitabilityRevenue and margin compared with the cost of serving the customer

This gives employees a reliable customer view and gives management a measurable process from the first enquiry to the final business result.Know the customer. Know the next action. Connect every promise with delivery.

Frequently Asked Questions

What is CRM - Frequently asked questions

  • What is CRM in simple terms?

    CRM stands for Customer Relationship Management. It is a system for managing relationships with potential and existing customers. It keeps customer information, communication, opportunities, quotations, tasks, and follow-up activities in one organized place.

  • What is a CRM system used for?

    Businesses use CRM to capture leads, maintain customer records, manage sales opportunities, coordinate communication, prepare quotations, schedule follow-ups, forecast revenue, and improve customer service.

  • Is CRM only for sales teams?

    No. Sales teams are common CRM users, but marketing, customer service, project teams, field service, finance, and management may also need customer information. Each user should only access the information required for their responsibilities.

  • What is the difference between CRM and ERP?

    CRM focuses on leads, customers, communication, and sales opportunities. ERP manages wider business processes such as orders, purchasing, inventory, manufacturing, projects, service, delivery, invoicing, finance, and human resources.

  • Can CRM and ERP be one connected system?

    Yes. An integrated CRM and ERP can share customer, product, order, delivery, invoice, and service information. This reduces duplicate data entry and creates one continuous process from the first enquiry to payment, service, and repeat business.

  • Why should CRM be connected to ERP?

    A standalone CRM can show what the customer wants, but it may not show whether products are available, materials must be purchased, production has capacity, delivery is complete, or an invoice has been paid. Connecting CRM with ERP gives sales teams the operational and financial context they need.

  • Does a small business need CRM?

    A small business may need CRM when customer information, leads, and follow-up activities become difficult to manage through email and spreadsheets. The need depends more on the number and complexity of customer relationships than on company size.

  • When should a company move from spreadsheets to CRM?

    A company should consider CRM when leads are missed, records are duplicated, several employees need the same customer information, follow-up depends on memory, or management cannot produce a reliable sales forecast.

  • How does CRM improve sales?

    CRM gives every lead and opportunity a clear owner, stage, estimated value, expected closing date, and next action. This helps salespeople prioritize their work and allows managers to identify inactive opportunities, delays, and missing follow-ups.

  • What is a CRM sales pipeline?

    A CRM sales pipeline is a structured view of active sales opportunities organized by stage. It helps teams understand potential revenue, expected closing dates, sales bottlenecks, opportunity progress, and the work required to move each deal forward.

  • What is the difference between a lead and an opportunity?

    A lead is a person or company that may be interested in a product or service. An opportunity is a qualified potential sale with a clearer need, estimated value, responsible salesperson, expected closing date, and defined next action.

  • Can CRM automate follow-up activities?

    Yes. CRM can create reminders, tasks, approval requests, renewal activities, overdue-opportunity alerts, and escalation steps. Automation should support employees without removing human judgment from important customer and commercial decisions.

  • How does CRM improve customer service?

    CRM gives employees access to customer history, communication, orders, agreements, complaints, warranties, and previous service activities. This helps them respond faster and prevents customers from having to explain the same situation repeatedly.

  • How does CRM support customer retention?

    CRM can highlight falling order frequency, declining order value, unresolved complaints, expiring contracts, missed follow-ups, and customers who have not been contacted recently. This allows the company to act before the relationship is lost.

  • What information should be stored in CRM?

    CRM should store information that supports a clear business purpose. This may include contact details, communication history, opportunities, activities, quotations, contracts, customer preferences, service information, and communication permissions. Companies should avoid collecting unnecessary personal data.

  • How does CRM support GDPR compliance?

    CRM can support GDPR processes through role-based access, communication preferences, consent records, retention rules, audit history, and controlled handling of data-subject requests. The software supports compliance, but the organization remains responsible for lawful processing and correct configuration.

  • What causes CRM implementations to fail?

    Common causes include unclear sales processes, poor data quality, weak management support, too many mandatory fields, insufficient training, low employee adoption, unnecessary automation, and a CRM that remains disconnected from operational systems.

  • How long does CRM implementation take?

    Implementation time depends on process complexity, data quality, integrations, customization, user numbers, and training requirements. A simple setup may be completed relatively quickly, while a connected CRM and ERP implementation across several departments requires more analysis, testing, and preparation.

  • How should a company choose a CRM system?

    A company should test the CRM using a real customer journey. The demonstration should show how an enquiry becomes a lead, opportunity, quotation, order, delivery, invoice, and follow-up activity. The company should also evaluate usability, reporting, permissions, automation, mobile access, integrations, and implementation support.

  • Which CRM metrics should a business track?

    Useful CRM metrics include lead response time, lead conversion rate, opportunity win rate, sales-cycle duration, pipeline value, forecast accuracy, average order value, repeat-purchase rate, customer retention, and customer profitability.

  • Can CRM connect with inventory and production?

    Yes. When CRM is connected to ERP, customer demand can be checked against available stock, expected deliveries, purchasing requirements, production capacity, and manufacturing plans. This helps sales teams make more reliable customer commitments.

  • Can CRM connect with invoicing and finance?

    Yes. Connected CRM and finance processes allow employees to follow a customer relationship from opportunity and quotation through order, invoice, payment status, revenue, and profitability. Access to sensitive financial information should remain role based.

  • What makes SIX CustomerFlow different from a standalone CRM?

    SIX CustomerFlow connects customer records, leads, communication, activities, and opportunities with the wider SIX ERP environment. Customer demand can continue into quotations, orders, inventory, purchasing, manufacturing, delivery, service, invoicing, finance, and reporting without rebuilding the transaction in separate systems.

  • Can SIX CustomerFlow be introduced without implementing every SIX ERP solution?

    Yes. A company can begin with CustomerFlow and the connected processes it currently needs. Additional SIX Flows can be introduced as the business develops without creating a new, disconnected customer database.

  • Does SIX CustomerFlow support different business processes?

    Yes. CustomerFlow can be configured around the company’s actual lead sources, qualification rules, pipeline stages, customer segments, responsibilities, approval requirements, activities, and reporting needs.
