The trick is separating the fixed and the variable. The base rate — depot to terminal — is genuinely fixed. Peak-hour multipliers, waiting-time and meet-and-greet are variable and should be quoted as line items, not folded into a single opaque number.
Ridezora exposes each of these as its own rule. Peak-hour windows are configurable per airport, per direction and per day of week. Waiting time bills after a grace period the operator sets — thirty minutes for domestic, sixty for international is a common baseline. Meet-and-greet is a checkbox at quote time with a fixed uplift.
The corporate implication matters. Travel managers hate surprise line items on invoices. When peak-hour and waiting-time rules are transparent at booking, the invoice shows a matching line — no dispute, no chased email, no goodwill discount.
The runway rule of thumb: if you can't defend a line item to a travel manager in one sentence, it shouldn't exist.
