Is it advisable for the company's multiple branches to share a single bank account?

Because a single bank account encompasses the income and expenses of all branches (the bank statement must be quite lengthy), distinguishing customer repayment records also requires time.

The bosses surely want each branch to have a more planned cash flow, at least knowing which of branches 1, 2, or 3 needs capital turnover and which can provide subsidies, etc.
 

Such as: Branch 1 suddenly faces an unforeseen circumstance, impacting its income and available cash flow.

At this point, the boss can be aware of this issue and make relative adjustments.

Furthermore, suppose branches 1, 2, and 3 intend to borrow a loan to expand their businesses. In that case, the bank can only assess the credit risk based on 'one' bank account.

Conversely, if branches 1, 2, and 3 each have their own bank account, with precise cash flows known, the bank can also observe whether the credit limits for each branch remain within a reasonable range. Of course, having separate bank accounts for each branch also aids in financial planning.
