A buy box is the deal profile a funder will actually fund.
Not what their website says. Not what their AE pitched at deBanked CONNECT. What their underwriters approve at 3 PM on a Tuesday with the queue full and the senior UW tapping her foot.
Every funder has one. The box has walls: minimum time in business, minimum monthly revenue, FICO floor, NSF tolerance, position rules, industry restrictions, state exclusions. Send a deal that fits the box and it funds. Send one that misses by 5% on revenue and it declines. There is no middle.
Brokers who don't think in buy boxes do the same thing every week. They blast the same file to 15 funders and pray. Two things happen, and the second one is worse.
First, their pull-through rate (funded ÷ submitted) sits under 5%. That's industry-burnout territory. It's also the math of a broker who's about to quit in six months and doesn't know it yet.
Second, funders track submission quality. Blast a low-fit deal across enough desks and you don't just get declined. You get flagged. Flagged ISOs get slower responses, worse offers, and eventually shut off. Most new brokers are quietly blacklisted from 3–5 funders inside their first six months and never figure out why their submissions stopped getting answered.
Buy box thinking inverts the flow. You stop matching deals to funders. You build a mental catalog of funder boxes, and the second a merchant fills out an app, the right 2–3 destinations are already obvious. That's what separates the 5% pull-through ISO from the 40% pull-through ISO. Same merchants. Different brain.
Five questions route any deal to the right 2–3 categories.
They route any incoming deal to the right 2–3 categories. Ask them in order. Write the answers on the application if you have to.
- < 6 mo Credit-Based stacking primary. Everything else is a long shot.
- 6–12 mo MCA, Equipment (with invoice), Fix-and-Flip (if RE investor).
- 12–24 mo Add Term, LOC, Factoring.
- 24+ mo All categories on the table, including SBA.
- < $10K Credit-Based or specialty MCA only.
- $10K–$25K MCA primary, some LOC fintechs.
- $25K–$100K Add Term, LOC, Equipment.
- $100K+ SBA, bank term, factoring at scale.
- < 600 MCA, Factoring (if B2B), Equipment (with strong industry experience).
- 600–680 Most fintech term and LOC open up.
- 680+ SBA, bank term, Credit-Based stacking.
- 700+ clean Everything, including the cheapest money on the menu.
- Yes Specialty funders only. Expect fewer options and higher cost.
- No Standard category routing applies.
- Working capital, urgent MCA.
- Equipment purchase Equipment Financing.
- B2B with unpaid invoices Factoring.
- Real estate acquisition or rehab Real Estate–Backed.
- General expansion, predictable payment Term or SBA.
- Lumpy cash needs or inventory cycles LOC.
- Pre-revenue startup capital Credit-Based.
Run the five answers. The right 2–3 categories fall out. Skip the rest. Submit where it fits. Stop shotgunning.
The fifteen industries most Tier 1 funders won't touch.
No universal list. Every funder writes its own. But the overlap across the industry is real. Most Tier 1 funders won't touch the following in 2026, or will only fund them through specialty channels at higher cost.[26][27]
- Adult entertainment and adult content
- Cannabis and cannabis-adjacent
- Firearms and ammunition sales
- Gambling, casinos, online gaming
- Auto dealers (new and used)
- Money services businesses
- Law firms on contingency
- Trucking (selectively funded)
- Multi-level marketing / direct sales
- Crypto and digital-asset businesses
- Political campaigns and organizations
- Non-profits
- RE investment with no operating business
- Travel agencies and tour operators
- Collections agencies and debt buyers
The list shifts. Cannabis policy is moving state by state in 2026. What's restricted in one state is fundable in another under the right charter. Trucking restrictions tightened across most MCA funders after the 2024 default cycle. Always verify current appetite with the funder before submitting.[28]
One real deal, end to end.
The five questions, run live on a restaurant equipment deal: with the verdict, the backup, and why the "obvious" alternatives are wrong.
The deal
Restaurant owner, 18 months in business, $45,000/month in revenue, 620 FICO, wants $30,000 to replace a walk-in cooler and upgrade kitchen equipment.
-
01
Time in business?
18 months. Most categories open. SBA tight (under 2-year floor).
-
02
Monthly revenue?
$45K/mo. MCA, fintech Term, LOC, Equipment all in play.
-
03
Personal FICO?
620. SBA and bank term out. Fintech Term marginal. MCA, Equipment, fintech LOC live.
-
04
Industry: restricted?
Restaurant. High-risk across most MCA funders, but fundable. Equipment with an invoice is straightforward.
-
05
Use of funds?
Equipment purchase with a vendor invoice. Points straight at Equipment Financing.
Equipment Financing
The merchant has an invoice, the equipment holds resale value, and equipment lenders underwrite the equipment nearly as much as the borrower. A 620 FICO with 18 months TIB and $45K/mo revenue clears most Tier 1 equipment buy boxes with 10–20% down. Likely offer: 48–60 month term, 12–18% APR, roughly $650–$780/mo payment. Broker commission: 5–8 points on the $30K = roughly $1,500–$2,400.
MCA
If equipment financing declines (wrong vendor, thin bank statements), the merchant clears the MCA Tier 1 buy box. 18 months TIB, $45K/mo revenue, 620 FICO, restaurant is fundable at specialty MCA houses. Likely offer: $30K advance at 1.35 factor, 8-month term, daily ACH of roughly $210. Broker commission: 8–12 points = $2,400–$3,600.
620 FICO misses the 680+ threshold. 18 months TIB is under the 2-year floor most PLP lenders want. Even an exception lender takes 45–90 days to close. The cooler dies before the loan funds.
Restaurant is B2C. No commercial invoices.
620 FICO is below the 700+ threshold for effective stacking. Inquiries would tank the file for months with no approval to show for it.
Equipment Financing primary, MCA backup. Two submissions. Probable pull-through 70%+. Expected commission $1,500–$3,600. That's the gap between a 40% pull-through broker and a 5% pull-through broker on the same deal. Two submissions instead of fifteen.
Why no lender names appear in this report.
Lender relationships are the single most valuable asset in this industry. The brokerages that know which funders to call, who underwrites what, and who approves fast: those are the brokerages that dominate. Publishing that intelligence for free does two things, and both of them are bad.
It destroys the asset for the brokers who've earned it. And it floods the funders themselves with unqualified submissions, which poisons the channel for everyone working it the right way.
Accelerator students get the full Lender Matrix: 200+ lenders by buy box, submission quirks, AE contacts, current appetite, rate sheets. After signing the Code of Conduct. That protects the lenders, protects the students, and protects the integrity of the network. If that sounds gatekept, it is. On purpose.
The full map is Accelerator-only.
This section gave you the eight categories and the composite buy boxes. The full Lender Matrix is 200+ funders by buy box, with submission quirks, current appetite, and AE contacts. It opens to Accelerator students after the Code of Conduct.
