Separate staff responsibilities clearly
Sales coordinators, event managers, front-desk employees, food-service teams, supervisors, and accounting staff may need different information and different capabilities. Document which roles may create or change an event order, initiate a payment, view transaction details, retrieve a receipt, complete an approved adjustment, or export a report.
Role design should follow actual responsibilities. Shared credentials and broad access make it harder to understand who took an action and harder to remove access when duties change. Ask the provider to demonstrate account creation, role assignment, authentication, activity history, and access removal for the proposed system.
Training should cover normal tasks and exceptions. Use fictional customer and payment details when practicing. Employees should know how to recognize the authoritative payment result, where to record a venue reference, what information belongs outside ordinary notes, and when an unresolved issue must be escalated.
