The money timeline for a dated booking.
Create the deposit invoice and send it with the booking confirmation.
Note on the deal that the place is held until the deposit clears.
Set the balance invoice for the date the terms say.
Chase the balance three days after it is due, and tell me if it is still unpaid a week before the date.
These are instructions for the assistant, carried out one at a time against your real records. Each one still goes through the same checks as if you had asked for it yourself.
Once you have an account, ask for "Deposit and balance" and it is added as your own recipe. From then on it runs on your records, not on an example.
Run it on every enquiry, whatever channel it came in on.
The week before. Every question they were going to ask, answered first.
The message that turns a no-show into a rebooking.
Run it when a date is close and under capacity.
Same day or the next morning, while it is still fresh.
A group is a different sale. Slower, bigger, and it needs a decision maker.
