Fast Funding Programs

Approval for merchant cash advance ISO is based on bank account verification and merchant interview.

Ideal for businesses in operation for 2+ years, with no NSFs, overdrafts, or negative days. No negative information must be found regarding the business or its principles, and businesses with large rent payments will have payments verified.

Escrow Program

Ideal for merchants who want to receive funding prior to paying off an existing merchant cash advance from another lender.

After funding with Greenbox Capital, the merchant must contact their other lender and disclose they have been funded by us, request to satisfy their balance, and provide us with a payoff letter.

Early Pay-Off Program

Business owners have the option to pay off their working capital loan at 30, 60, or 90 days from the date of funding to receive a discount. Factor rate reductions are granted for every 30 days early.
