Pointing out the obvious: The issue is the SBA loan: if they have a blanket UCC (which they nearly ALWAYS do), all of the assets (collateral) of the business are encumbered. The Bank would have to carve out the receivables (which can be done- but takes time and a forward thinking decision maker).

If the client has grown since taking out the SBA, they might be eligible for a larger facility. If not, people like Funding Circle subordinate to Senior Debt- but Debt Service Coverage and a strong guarantor will be the key.
