What it means
A treasury structure, not a product. One master account holds the cash; the subsidiary accounts exist to segregate activity.
The point is control and visibility: each account shows a clean record of one activity, no balance sits idle in the wrong place, and exposure to a compromised account number is limited to the day's items.
Where it meets financing
Where this one catches people
If you run a sweep structure and apply for deposit-based funding, supply the whole structure — master and subsidiaries — with a one-paragraph explanation, on day one. An underwriter handed a single swept account sees daily zero balances, no cushion, and large outbound transfers to an account they cannot see. Every one of those reads as a business in trouble or as money being moved, and the offer is priced accordingly if it comes at all.
The second issue is operational and it catches businesses that are not in trouble at all. An ACH debit presented against a subsidiary account that is not funded that day will return. Under an advance or loan agreement, a returned debit is typically an event of default in its own right, entirely regardless of how much money is sitting in the master account an hour later. If you take a facility with fixed debits, either point the debits at the funded master account or make certain the funding instruction covers them before the presentment cut-off.
