CRM Field Validation Best Practices: Keeping Your Data Clean

Why Field Validation Matters

Bad data enters CRMs through poorly validated fields. Invalid email addresses, incorrect phone numbers, and inconsistent formats undermine reporting, automation, and integration. Good validation prevents garbage in while keeping user experience smooth.

Required Fields

Require only truly essential fields:

• Contact: Name, Email (Phone if business critical)
• Account: Name, Industry
• Deal: Name, Value, Stage, Close Date

Requiring too many fields slows data entry and encourages users to enter fake data.

Format Validation

Email

• Must contain @ and valid domain format
• Block known fake domains (test.com, fake.com)

Phone

• Standardize to E.164 format (+15551234567)
• Accept various input formats but store consistently

Date

• Close date cannot be in the past
• Birth date cannot be in the future

Conditional Validation

Validation that depends on other fields:

• If Stage = "Closed Won," require Actual Close Date
• If Deal Value > $50K, require Approval Status
• If Contact Type = "Customer," require Account

Error Messages

Write helpful error messages:

• Bad: "Invalid input"
• Good: "Please enter a valid email address (e.g., name@company.com)"
• Bad: "Required field missing"
• Good: "Close date is required when stage is Closed Won"

Validation Testing

• Test with valid data
• Test with intentionally invalid data
• Test boundary values
• Test with null/empty values
• Verify error messages display correctly
