CRM and ERP Selection Guide

CRM and ERP systems are often mentioned together, but they solve different problems. This guide helps you decide which you need, in what order, and whether to buy or build.

CRM vs ERP in one line each

• CRM (Customer Relationship Management) manages the journey from enquiry to sale and the relationship afterwards.
• ERP (Enterprise Resource Planning) manages internal operations: purchase, inventory, production, dispatch and accounts.

Which do you need first?

Choose CRM first if your main pain is lost leads, slow follow-ups or no visibility into sales.

Choose ERP first if your main pain is stock mismatches, production delays, purchase errors or slow month-end closing.

Many growing businesses start with a CRM, then add ERP modules as operations scale.

Step 1: Map your process

Draw your process from first enquiry to cash received. Mark where information is re-entered, where delays occur and where errors happen. These points define your must-have features.

Step 2: List requirements by priority

Step 3: Evaluate ready-made options

Ask vendors:

• Does it support our must-have features without heavy customisation?
• What is the total cost for our user count over three years?
• Can we export all our data at any time?
• What integrations are available out of the box?
• What support is available in our time zone and language?

Step 4: Consider custom development

Custom systems are worth considering when:

• Your process is unusual or a competitive advantage.
• Per-user licences become expensive at your scale.
• You need several systems unified.
• You want full ownership of data and roadmap.

Our custom software requirements template helps you document needs.

Step 5: Score your options

Score each option from 1 to 5 on: feature fit, ease of use, integration, three-year cost, vendor reliability and data ownership. Weight the criteria by importance to you. The highest weighted score wins.

Step 6: Plan implementation

• Start with one department or module.
• Clean data before migration.
• Train users with real scenarios.
• Run old and new processes in parallel briefly.
• Review adoption after 30 and 90 days.

Common mistakes

• Choosing the tool with the most features rather than the best fit.
• Skipping user training.
• Migrating messy data without cleaning it.
• Implementing every module at once.
