Seven products fund small businesses quickly. The fastest close same day. The most affordable close in 48–72 hours.
Speed and cost are inversely related. Decide which matters more before you apply.
Speed vs. Cost: The Core Trade-Off
Every fast-funding product makes the same trade-off: the faster it closes, the more it costs. This is not a coincidence. It's the structure of the risk premium.
Same-day MCAs require automated underwriting — which means less due diligence and higher factor rates. 72-hour revenue-based financing allows time for proper underwriting, which produces lower rates.
The right question isn't "what's the cheapest option?" It's: "what's the cheapest option that still closes within my required window?"

How to Prepare for the Fastest Approval
Three things slow down quick funding: missing documents, inconsistent bank statements, and applying late in the day.
Before submitting any application: compile 6 months of business bank statements as complete PDFs, have your EIN documentation ready, and confirm you're applying to a product that matches your advance amount need.
Applying for $500,000 in the same-day window won't work — larger advances route to manual review. Keep same-day applications under $100,000.
