Are there origination, underwriting, or platform fees I should expect?

There may be, and they should be disclosed clearly.

Common fees:

• Origination or underwriting fee(flat or a small percentage of the advance)
• Platform/servicing fee, if the provider runs a portal or app
• Third-party feeslike PPSA registration or legal costs on larger deals

You want a complete funding summary that shows each fee separately, so you can compare offers fairly.
