Currently the credit limit functions only consider the invoice account. Reference:

In actual businesses, there're scenarios in which multiple customer accounts have their invoices charged to a single head office account. However, these are individual stores that are owned by franchisees, and the financial viability of these individual stores will vary.

The Head Office will allow most stores to order without checks but insist that authorization needs to be gained from them before new sales orders from specific customers in specific conditions can be confirmed.

In such scenario, the current system design is not feasible as the credit limit information of all stores are controlled by the head office account instead of their own customer accounts.

Please highly consider adding an option to let users select whether credit management should be checked against the main customer account, or the invoice account.
