Only if the billable outcome is defined well enough to audit. Our recommendation is to negotiate the outcome definition before comparing the headline price.
For a booking-based contract, specify:
- The correct customer, location, service and appointment type.
- Whether the booking must be written and verified in the operational system.
- How duplicates, reschedules and cancellations are treated.
- Whether a human-completed booking is billable at the same rate.
- Which rules make a booking invalid.
- How disputes are evidenced and credited.
- Whether fees depend on a booking, attendance or completed service.
Distinguish supplier-caused defects from later customer decisions. A wrong-location booking is different from a valid appointment cancelled by the customer for an unrelated reason.
Request sample invoices for ordinary, transferred, duplicate, failed and later-cancelled cases. Model the same workload under each pricing structure.
Do not assume outcome pricing removes implementation or monitoring costs. Include every contract charge in the comparison, whichever billing unit the supplier chooses.
