They are not the same document, they are not written by the same author, and substituting one for the other is the most common reason a condition comes back unsatisfied.
A feasibility study is an independent test of whether a project is viable. A business plan is the sponsor's statement of how the business will be run. The first is written by someone with no stake in the answer; the second is written by the people whose plan it is. That difference in authorship is the whole point, and it is why a lender that asked for a study will not accept a plan.
| Feasibility study | Business plan | |
|---|---|---|
| Core question | Is the project viable on evidence? | How will the sponsor operate and grow it? |
| Author | Independent, no financial interest | The sponsor, or a writer engaged by them |
| Stance | Neutral; may conclude the project is not viable | Advocacy; assumes the project proceeds |
| Evidence standard | Every material figure sourced and checkable | Assumptions stated, sourcing optional |
| Market work | Primary and secondary research, competitor inspection | Usually secondary summary |
| Financials | Projections tied to market findings and stress-tested | Target-driven projections |
| Typical trigger | Lender or agency condition | Investor pitch, internal planning, some loan packages |
| Can it conclude "no"? | Yes, and it must if the evidence says so | Effectively never |
Borrowers are quoted for the wrong document constantly, usually because the loan officer's condition list says something like "third-party analysis supporting projections" and a business plan writer answers the phone first. The plan arrives, the reviewer reads three pages, and the condition comes back unsatisfied — with the loan now several weeks older.
The tell is authorship. If the document was written by, or paid for on a contingent basis by, someone with an interest in the loan closing, it cannot satisfy an independence requirement no matter how good the analysis inside it is. The second tell is the conclusion: a document that could not have concluded against the project is not a test.
Frequently. USDA and SBA files often include a business plan describing the operation and management alongside an independent feasibility study testing the projections. They serve different functions in the credit file: the plan tells the lender who is running this and how, and the study tells the lender whether the numbers behind it hold.
Where both are required, they must agree. Two documents on the same file with different revenue assumptions is a finding in itself — and it is the sponsor, not the analyst, who pays for it in re-underwriting time.
Ask your loan officer to put the requirement in writing, and read the words. "Independent feasibility study", "third-party market study", "business plan" and "appraisal" are four different documents with four different standards and four different authors. We will read the condition with you at no charge and tell you plainly which one it is — including when the answer is that you do not need us.
