Messaging tools are valuable for speed but risk exposing sensitive customer information and losing the record. Ask before adding guests to a group, explain its purpose, use direct messages for sensitive information, never post internal risk notes and record decisions in the CRM. Collect only the data you need, control who can access it, and prepare printed and offline backups, tested before guests arrive.
The convenience of a group chat is also its risk: everyone in it sees everything, and no one is accountable for the record.

| Decisions may not reach all owners | Actions are missed |
| Identities are exposed | Participants may not want contact details shared |
| Personal and business mix | Boundaries blur |
| Consent and retention are unclear | Data may be kept without a purpose |
| The group continues after the event | It has no defined purpose |
