The best CRM software: 8 criteria that actually decide it

Choosing a CRM sets how your company sells, serves and reports for years. These are the criteria worth weighing, and what the market data says about each.

Selecting the best CRM software is a decision you live with far longer than the procurement process suggests. It shapes what your sales team focuses on, what your management can forecast, and whether customer knowledge belongs to the company or to individuals.

This guide sets out eight criteria and what the published market data says about each.

What a CRM is for

A CRM holds customer information, opportunities, quotes and communication history in one place. A good one makes priorities clear to the sales team, gives management a forecast worth trusting, and ensures that when someone leaves, the relationship stays with the business.

The market in numbers

Salesforce publishes the following figures, citing IDC data from 2025 and Gartner’s 2025 evaluation:

Indicator Salesforce
Worldwide CRM market share (2025) 20.0% — first place
Consecutive years as CRM market leader 13
Sales software 14 consecutive years in first place
Customer service software 13 consecutive years in first place
Marketing software 7 consecutive years in first place
Gartner 2025 Sales Force Automation evaluation Positioned as a Leader

Market share is a signal about longevity, not a guarantee of fit. It belongs in the decision alongside the criteria below rather than in place of them.

The 8 criteria

1. Proven market position and continuity

A CRM is a long-term commitment. You need confidence that the platform will still be invested in, developed and setting direction a decade from now. On the IDC figures above, Salesforce has led the market for thirteen consecutive years.

2. Sales, service and marketing on one platform

When those three live in separate systems, seeing the customer whole becomes impossible. Salesforce ranks first in each of the three areas individually and combines them on the same customer record.

3. Customisation and scalability

Every company’s sales process, approval flow and data structure differ. The best CRM software lets you create custom fields, objects and automation without code, and extend without limit when code is needed. Salesforce runs from Starter and Pro Suite for small teams up to enterprise scale on the same platform, so growth does not require changing systems.

4. Integration depth

A CRM that does not talk to your ERP means double data entry and unreliable reports. Salesforce connects to ERP systems, e-commerce platforms and web forms through APIs, MCP servers and the thousands of ready-made applications on AppExchange.

5. Artificial intelligence

In 2026 the expectation is no longer storage. It is prioritising opportunities, preparing for meetings and running AI agents that do the work. Salesforce is among the platforms increasing investment here fastest, through Agentforce and the Claudeforce collaboration with Anthropic — explained in our guide to Claudeforce.

6. Multilingual and multi-currency operation

For companies operating across borders, it matters that each user can work in their own language and that several currencies can be managed in one system rather than in parallel instances. Salesforce supports per-user language selection and multiple currencies within a single org.

7. Security and permissions

Customer data is usually a company’s most valuable asset. Who can see which record — and which field on that record — needs to be controllable in detail. Salesforce provides this through role hierarchy, sharing rules and field-level security.

8. Independent analyst assessment

Vendor claims are worth checking against independent evaluation. Salesforce was positioned as a Leader in Gartner’s 2025 Magic Quadrant for Sales Force Automation Platforms.

Criteria checklist

Artificial intelligence Agents and automation Agentforce, Claudeforce
Localisation Language and currency Per-user language, multi-currency

Five common mistakes when choosing a CRM

  1. Judging on today’s licence price alone. Changing systems once you have grown costs far more than the licence difference ever did.
  2. Implementing before defining the process. Clarify how you actually sell first, then configure the CRM around it.
  3. Leaving users out of the decision. A CRM configured without the sales team’s input tends to go unused.
  4. Postponing integration. A CRM that does not talk to the ERP means double entry from day one.
  5. Working without an experienced partner. A capable platform only delivers value through a sound implementation.

The second mistake is the expensive one. A CRM makes an existing process visible and repeatable; it does not create one. If follow-up is inconsistent today, new software will record that inconsistency more precisely and change nothing.

Frequently asked questions

Which CRM is most used worldwide?

On IDC data published by Salesforce, Salesforce held a 20 per cent market share in 2025 and has been the leading CRM provider for thirteen consecutive years.

Is there a suitable CRM for small businesses?

Yes. Salesforce’s Starter and Pro Suite editions are built for small and mid-sized teams, and companies can move up to higher editions on the same platform as they grow.

Can one CRM handle multiple languages and currencies?

Yes. Salesforce allows each user to select their own language and supports multiple currencies within a single org, which matters for companies operating across several markets.

How long does a CRM implementation take?

It depends on scope. A basic sales implementation can be completed in a few weeks; projects involving ERP integration and custom processes can run to several months.

Does market share mean a CRM is right for us?

No. Market share indicates that a platform is likely to still be invested in years from now. Whether it fits your requirements is a separate question, answered by the other seven criteria.

What is the most common reason CRM projects disappoint?

Implementing before the sales process is defined. Software makes an existing process repeatable; it cannot substitute for one that was never agreed.

Conclusion

The best CRM software is the one proven in the market, combining sales, service and marketing on one platform, shaped around your process, connected to your other systems, and using AI to speed the work up. Pair the right platform with the right implementation and the CRM stops being a cost line and becomes the engine of growth.
