Our app is somewhat unique in how the pricing structure works.
The customer is charged purely on time (per minute).
When a customer books a job, the system will produce an estimated time & price based on a number of various inputs.
For e.g. customer is given an estimate of $30 @ $1.00 per minute x 30 mins. Currently, the customer saves credit details to their account and payment is taken after the actual work for the customer is completed and we know the actual mins the job took to complete. E.g. $45 @ $1.00 per minute x 45 mins. Thus being a $15 difference between the estimated price and the actual price. In some examples, the final price ends up being less than the estimate. (Stripe is the payment gateway we use)
So my question is, does Apple Pay have the capability to take payment AFTER the job is completed and we know the final minutes & cost of the job, or must the payment be taken when the customer schedules the booking in the app and the payment be based on the estimate?
