The Definition, From the Forum Where Brokers Actually Discuss It
The clearest definition on record comes from DailyFunder user Yankeeman07, in a thread titled plainly "What does backdooring mean": "You submit an application to a so-called funder and the inside rep/underwriter of said shop sells the app to the office next door," leaving the merchant "slammed with funding calls" from competitors who never earned the introduction. That is the core mechanism: a broker does the work of finding and qualifying a merchant, submits the application in good faith to a funder, and somewhere inside that funder's office the submission gets shopped elsewhere without the broker's knowledge or consent.
How It Plays Out in a Real Submission
A live complaint thread on DailyFunder captures the pattern in practice: a broker described a funder representative contacting their submitted merchant directly within roughly an hour of the original submission, pitching alternate numbers, then ending the call abruptly when confronted about it. The same thread shows brokers actively compiling and disputing lists of funders accused of the same behavior, a debate active and detailed enough that it reads less like a rare complaint and more like an ongoing industry argument about which funders can still be trusted with a raw submission.
deBanked's Own Framing: Getting Cheated Out of the Commission
deBanked, the industry's primary trade publication, has covered this directly in two separate pieces. "Did Your Deal Slip Out The Back Door?" frames it as brokers getting cheated out of the commission they earned by sourcing and qualifying a deal, only to have it quietly shopped to other funders without credit to the originating broker. A later piece, "Backdooring Deals? You're a Loser," takes an even blunter editorial position, treating the practice as a reputational failure within the industry rather than a normal cost of doing business.
Why Industry Veterans Call It "Part of the Space" Now
In the same DailyFunder thread where the Eagle Funding-style complaint appears, veteran poster TStein offers a resigned summary: "the days of an exclusive merchant are far gone," calling backdooring "part of the space. Get used to it." That framing, from someone who has clearly been in this business long enough to have watched the pattern repeat, is worth taking seriously as a description of the market's current baseline, not as an endorsement of the practice.
Backdooring vs a Legitimate Decline-and-Resubmit
It is worth separating backdooring from ordinary, above-board deal flow. A funder declining a deal and the broker legitimately resubmitting it elsewhere is normal and expected: the broker controls that decision and knows where the application is going. Backdooring specifically describes the funder's own side taking that action without the broker's knowledge, using information the broker only shared because they believed the submission was confidential to that one funder relationship. The difference is who is making the decision to shop the deal, and whether the broker who did the sourcing work knows about it.
Why This Matters Before You Even Talk About Lead Vendors
Backdooring happens downstream of where most vendor-vetting conversations focus. You can vet a lead vendor thoroughly, get exclusivity in writing, confirm the data is fresh, and still lose a deal to backdooring once the application leaves your hands and reaches a funder's underwriting desk. That is why the practical fix, covered in the companion guide on how to avoid getting backdoored, is less about who you buy leads from and more about who you submit applications to, and how.
What this means for you
- Backdooring is a funder-side failure, not a lead-vendor failure: it happens after a broker submits an application in good faith, not before.
- DailyFunder forum evidence and deBanked's own trade coverage both treat it as common enough to name and discuss openly, not as a rare exception.
- Vetting your lead vendor does not protect you from backdooring. That risk lives in your funder relationships and submission habits instead.
