    How to Submit Deals to Diesel Funding

    Diesel Funding is a direct merchant cash advance funder working with ISO and broker partners. Here's how to submit a complete file for review.

    1Become a partner

    Sign up through our partner page. Our team will get you set up with a signed ISO agreement — usually the same day.

    2Submit your deal

    Send your submission with the merchant's application and recent bank statements. Complete files get the fastest turnaround.

    What we fund

    Performance-based underwriting. No hard credit pull is required to apply, and there is no FICO minimum. We focus on cash flow and revenue stability and consider B paper through D paper. Review the current ISO buy box before submitting.

    Beyond standard advances, we underwrite MCA reverse consolidations (reverses) in-house for merchants with stacked positions — a weekly deposit structure that lowers the merchant's total weekly outflow while existing positions keep remitting on schedule. We also offer staged (tranched) funding, where a larger approval is delivered in scheduled installments. If your merchant is consolidating MCA positions or needs a reverse program, send the file — each deal is underwritten individually. Learn more in our broker guide to reverse consolidation and staged funding.

    3Get your offer

    Our underwriting team reviews submissions quickly — decisions in as little as 24 hours. Offers spell out all terms clearly.

    4Fund and get paid

    Once docs are signed and verified, funding moves fast — as fast as same day. ISO partners earn competitive same-day commissions on funded deals.
