Price is only one effect of an extra
A fictional consultation may offer an additional setup service that adds twenty minutes and needs a specialist tool. Treating that option only as an extra charge misses its operational effect. Write down whether each add-on changes duration, resource quantity or staff eligibility. Some extras do none of these things; others change all three. Keep the distinction explicit before deciding which options customers can select in an automatically confirmed booking.
Check the supported model
Trafft’s service configuration documentation is the starting point for understanding its service options. It does not justify assuming every combination of extras can change every type of resource assignment. Map the exact required behavior and mark unsupported details as unknown. If an extra effectively creates a different service, a separately defined appointment type may be clearer. This is a design option to evaluate, not a claim that one configuration is universally best.
Test the last appointment of the day
Take a fictional base service that fits just before closing. Add the time-consuming option and calculate whether the complete occupied interval still fits. Then try it when the extra equipment is already reserved. A correct price total does not prove either scheduling condition is satisfied. These checks should use fictitious customer information and an authorized test route, with expected outcomes recorded before observing the software.
Keep the customer description aligned
State whether an extra changes the appointment length and whether it is guaranteed or subject to confirmation. Avoid promising an add-on that staff must manually decline after booking. Review existing future appointments before changing an extra’s duration or resource requirement. A configuration edit may affect new availability without resolving earlier commitments. Keep those two tasks separate, and do not silently alter the service a customer already expects to receive.
