Read the grid correctly
A fifteen-minute grid does not mean every appointment lasts fifteen minutes. It can describe how often a customer is offered a starting time. A forty-five-minute service may occupy several grid units, plus any preparation or reset. Draw a sample day before changing the setting. This separates the number of displayed choices from the number of appointments the business can actually deliver and prevents a dense calendar from being mistaken for greater physical capacity.
Check the documented constraint
Trafft’s settings documentation connects the default time-slot step with service durations and offers choices for displaying slots using service duration and buffer time. Verify the current configuration rather than assuming every minute value is valid. A duration that does not fit the selected step can require a different setup. Do not silently round the real service down to make it fit the grid; that can create overlap later in the day.
Test a boundary rather than a screenshot
Choose a fictional working window with a known start and finish. Calculate which start times should accommodate the entire occupied interval. Then inspect the offered starts at the opening boundary, around an existing appointment and near closing. The purpose is to test the rule, not simply confirm that a calendar appears. A visually neat grid can still offer an appointment whose reset period extends past the available window.
Change the smallest relevant setting
If a slot is missing, first check service assignment, staff hours, resources and buffers. Do not reduce the grid step as a universal repair. A smaller step may create more choices without creating more usable capacity. Record the old and new settings and review any existing appointments affected by the change. Keep the customer-facing duration aligned with the service you deliver even when the internal scheduling grid uses a different interval.
