Create the customer in billing first; the slot calendar reads the code from billing. A customer created only in the calendar will book slots that nobody can invoice, and we have done this twice.
If the customer negotiates annex pricing, Finance holds the list. Do not quote the standard rate card to an annex customer and do not guess from the customer's name.
The sales owner hands over to customer service at the first delivery, not at signature. Anything agreed verbally before that is written into the annex or it does not exist.
Every new customer is reviewed at ninety days: volumes against forecast, exceptions raised, invoices disputed, and whether the notification class we agreed is the one they actually want.
