The most expensive business CRM on the market will not fix a team that logs its conversations in three different tools. A CRM (Customer Relationship Management) works as a customer database. It centralizes information about customers and prospects: contact details, interaction history, open sales opportunities and scheduled follow-ups. Every salesperson, every customer service agent and everyone in marketing then works from the same record.
What is a CRM used for in a company?
A CRM first stops information from getting lost between two colleagues. When a salesperson goes on leave, a teammate opens the customer record. There they find the last quote sent, the date of the next call-back and what was said on the previous call.
Daily use falls into 4 areas:
- tracking opportunities in a pipeline (“Qualification”, “Quote sent”, “Negotiation”, “Won” or “Lost”), with the amount and expected closing date of each deal;
- interaction history: Gmail or Outlook emails, calls, meetings and tickets opened with customer service;
- automatic follow-ups, such as a reminder when a quote has gone unanswered for 10 days;
- dashboards that measure the “conversion rate” at each stage, the average length of the sales cycle and customer lifetime value.
The clearest gain is retention: a customer contacted before their contract ends is more likely to renew. The other shows up on the phone, when the person calling customer service no longer has to explain the problem twice.
On the marketing side, segmenting by industry or by date of last purchase feeds marketing automation: one email sequence for a prospect who just downloaded a guide, another for a customer near the end of a contract. The criteria you pick (industry, company size, date of last purchase) change the result, and our piece on email segmentation covers the ones that work.
Adoption is lower than most people assume. According to Eurostat, 28.51% of European Union enterprises used CRM software in 2025, from 24.69% for small businesses to 65.43% for large ones. That leaves 71.49% of European companies without a CRM in 2025.
CRM or ERP: which one should you choose?
Choose the CRM if your difficulty is selling and following up with customers. Choose the ERP (enterprise resource planning software) if it is producing and invoicing; Sage, Odoo and SAP are examples. Most small and mid-sized businesses start with a CRM. They add an ERP once stock or payroll becomes impossible to track in Excel or Google Sheets.
| Criterion | CRM | ERP |
|---|---|---|
| Question it answers | Who are my customers, and where does each deal stand? | What do we produce, what do we hold in stock, what do we invoice? |
| Main users | Sales, marketing, customer service | Finance, purchasing, logistics, production |
| Core data | Contacts, opportunities, conversations, quotes | Stock, supplier orders, invoices, payroll |
| Typical rollout time | Often a few weeks as SaaS | Often several months with industry-specific setup |
| Sign that you are missing it | Lost quotes and forgotten follow-ups | Re-keying between order, stock and accounting |
The two tools meet through integration. A quote accepted in the CRM creates the order in the ERP, then the delivery status flows back into the customer record. Check this connector before buying: without it, every order is re-entered by hand, which brings back the errors you wanted to avoid.
One of the two tools is enough in many cases. A service agency with no stock does very well with a CRM and invoicing software. A factory selling to a few fixed distributors needs the ERP more. The deciding question is simple: where is the most money lost today, in sales follow-up or in the production and invoicing chain?
How to choose a CRM
Start from your processes and look at vendor catalogs afterwards. List the 5 actions your teams repeat every week (create a deal, chase a quote, hand over to customer service) and check that the CRM covers them without custom development.
5 criteria separate most offers:
- team size: a 10-person business does not need the modules of a large enterprise, which multiply the fields to fill in;
- the full budget, including the per-user monthly license, setup, training and paid connectors;
- integrations with Gmail or Outlook, Google Calendar, invoicing and your email marketing tool;
- access rights: an intern has no reason to export the entire customer base. Good CRMs set these permissions by profile;
- data hosting and GDPR compliance.
Salesforce Sales Cloud, HubSpot Sales Hub, Pipedrive and Zoho CRM are among the most cited SaaS solutions. Pipedrive focuses on the sales pipeline. HubSpot also covers marketing. Salesforce targets organizations with complex processes.
Open source CRMs exist too. They skip the license but leave hosting, updates and security to you, which mostly suits a technical team.

How to set up a CRM
Start with the data. Gather your salespeople to define the pipeline stages and the required fields on each record. Then open your Excel files: remove duplicates, fix obvious address errors, and import everything as a CSV with columns for Last name, First name, Company, Email and Phone. Connect the mailbox so that conversations land in the records on their own, then open access team by team during a pilot of a few weeks. Each week, note what the salespeople work around: a field that is never filled in or a stage that does not match how they sell should be fixed before the full rollout.
Adoption is won through immediate use. If salespeople find their follow-ups for the day in the CRM, they open it every morning. Set one rule: a deal that is not in the CRM does not exist in the sales forecast.
What the GDPR says about a CRM
A CRM holds personal data, so it falls under Regulation (EU) 2016/679, the GDPR, applicable since May 25, 2018. You must be able to justify the purpose of each record and limit how long it is kept. You must also handle requests for access (Article 15), rectification (Article 16) or erasure (Article 17).
On retention, the “commercial management” reference framework adopted in 2022 by the CNIL, the French data protection authority, allows you to keep the data of a prospect who is not a customer for 3 years from collection or from their last contact. A click on a link in an email counts as contact. Simply opening a message does not. At the end of that period, you can ask the prospect whether they want to keep receiving your messages. Without a positive and explicit answer, the record is deleted or archived. This period is a recommendation: you may depart from it as long as you document your choice.
For sending emails, according to the CNIL, prior consent applies in B2C and the right to object applies in B2B. Every message must let people refuse further mailings simply (Article L34-5 of the French Postal and Electronic Communications Code, a French provision). The rules on proof of consent are covered in our article on GDPR and email marketing. A person on file who asks for access to their data gets an answer within 1 month at most, with a few exceptions.
The GDPR also sets a principle of accuracy (Article 5(1)(d)). A record with an outdated or duplicated email address contradicts that principle as much as it hurts sales.
Why data quality decides what a CRM is worth
A CRM keeps everything you give it, including outdated addresses and duplicates. An address that no longer exists causes a hard bounce, a permanent rejection (SMTP error 550 5.1.1, mailbox does not exist), on the very first campaign sent from the CRM. Since February 1, 2024, Google requires senders to Gmail to keep their spam rate under 0.3% in Postmaster Tools. Google recommends aiming for 0.10% and avoiding 0.3%. A poorly maintained database weighs on sender reputation before the message is even read.
Hygiene starts at data entry with controlled fields and a mandatory “Contact source” field. It continues at import with deduplication, then before each big campaign with address verification. 3 articles on the blog dig into each step: the clean database for the method, data quality management for oversight and data deduplication for the import.
If the CRM is filled through prospecting, a qualified B2B email list keeps invalid contacts out. Verify a sample of the database before your next send: the share of invalid addresses will tell you whether to clean before following up. Then compare the hard bounce rate before and after cleaning in your email marketing KPIs.
Frequently asked questions about CRM
How much does a CRM cost?
SaaS CRMs charge per user per month, with tiers based on features. Add setup and training: the real budget almost always exceeds the license alone.
Is a spreadsheet enough instead of a CRM?
A spreadsheet works for a few dozen customers with a single user (Excel caps at 1,048,576 rows per sheet). As soon as several people edit the same rows, the history gets lost. Versions diverge too: that is the moment to move to a CRM.
Can you recover your data when switching CRM?
Most CRMs export contacts and deals as CSV. Check before buying that the export also covers conversation history and attachments. Keep a regular backup as well.
Where is CRM data hosted?
With a SaaS vendor, on its servers, sometimes with the option of a hosting region inside the European Union. Ask for the hosting location and the list of subprocessors before signing.
