I have seen this work when some training was included - which you could easily incorporate in your "helping" and hand holding, not necessarily training classes for groups (although banks do that too). Prepare materials so that you can provide to the customer and show to regulators showing how you helped them through the process, educated them on getting their financials in order for this process, all things you are probably doing now.
Explain why the application needs to be filled out a certain way, what information they need, how to respond to questions...you are doing that and it is training.
