// ## The customer balance
//
// The customer balance is an amount in the customer's currency, which Orb
// automatically applies to subsequent invoices. This balance can be adjusted
// manually via Orb's webapp on the customer details page. You can use this balance
// to provide a fixed mid-period credit to the customer. Commonly, this is done due
// to system downtime/SLA violation, or an adhoc adjustment discussed with the
// customer.
//
// If the balance is a positive value at the time of invoicing, it represents that
// the customer has credit that should be used to offset the amount due on the next
// issued invoice. In this case, Orb will automatically reduce the next invoice by
// the balance amount, and roll over any remaining balance if the invoice is fully
// discounted.
//
// If the balance is a negative value at the time of invoicing, Orb will increase
// the invoice's amount due with a positive adjustment, and reset the balance to 0.
//
// This endpoint retrieves all customer balance transactions in reverse
// chronological order for a single customer, providing a complete audit trail of
// all adjustments and invoice applications.
