The rule box is SBA 7(a) for manufacturing acquisitions. The base math is asset-based lending. The junior page is mezzanine and unitranche. Buy a manufacturing business stays the pillar.
| Criterion | SBA 7(a) | ABL | Mezzanine |
|---|---|---|---|
| What it is | Guaranteed change-of-ownership loan | Revolver / term against eligible assets | Junior capital after senior is maxed |
| Published size | $5 million standard max | Lender’s hold + base, not a 7(a) cap | No 7(a) box; larger-EV habit |
| Underwrite first | DSCR after a replacement wage | Eligible AR and countable inventory | Cash flow after senior and junior cost |
| Equity | 10% injection; standby note ≤50% | Equity still required; base is not a down payment | Equity already in; stretch is not the injection |
| Inventory / WIP | Valuation support; classes still matter | Eligibility exhibit; WIP haircut or exclusion | Ignored as magic; still sits in the peg |
| Typical seat | Individual operator; some searchers | Files above the 7(a) box or lumpy earnings | Sponsor / searcher stretch, not Main Street SDE |
| Cost shape | Guaranty + published structure | Unused-line and exam cost on top of rate | Current coupon, PIK, and sometimes warrants |
| Fails when | EV + fees + peg miss the box | Ineligible AR, concentration, job-cost fiction | Senior already fails; 40% customer; thin margin |
| Calendar drag | Packaging, SOP, appraisal | Field exam and opening base | Intercreditor and warrant paper |
| Seller tell | “No-cash close” folklore | Peg confused with availability | Junior hidden until week nine |
BizBuySell’s 2025 manufacturing median close was 223 days (Source: BizBuySell). Packaging, a field exam, and junior documents all sit on that clock. None of those figures is a close date.
What is each product actually buying?
7(a) buys a going concern the credit file can carry, including intangible value when the supported valuation allows it. It does not reprint cash flow. It does not excuse a dirty machine list.
ABL buys availability against eligible accounts, eligible inventory, and sometimes machinery against appraised orderly liquidation value. Ineligible items come out before any advance rate. This page will not publish a rate as if it were a quote. Confirm percentages with the institution that will sign.
Mezzanine buys extra leverage after senior ABL or cash-flow paper is already full. Warrants or payment-in-kind interest can appear. They are not free equity. Counsel reads that paper.
Where does the published size box sit?
Standard 7(a) maximum is $5 million (Source: SBA). SOP 50 10 8 wants a 10% equity injection on change-of-ownership files. A seller note counts toward that injection only on full standby for the life of the 7(a), and only up to half the injection (Source: SBA). Seller notes and standby is the companion.
SBA 504 is a different product: $5 million standard, $5.5 million on a qualifying small-manufacturer project (Source: SBA). Occupancy rules still apply. Combined 7(a) and 504 capacity is not a reason to treat ABL or mezzanine as folklore.
ABL and mezzanine have no 7(a) cap because they are not 7(a). Buying above the SBA cap is the rebuild page when enterprise value plus fees plus the peg will not fit.
Does the file live on cash flow or a borrowing base?
If cash flow after a replacement wage already covers senior debt, 7(a) or cash-flow senior can be the first call. BLS OEWS May 2025 median pay — machinist $58,750, welder $53,750 — is labor context for that wage line, not the owner’s salary (Source: BLS OEWS).
If earnings are lumpy or leverage is high, but the book has quality receivables and countable inventory, ABL can be the senior. Job-cost fiction becomes availability fiction. Progress-bill disputes, affiliate accounts, and aged invoices often leave the base.
If senior is already maxed and margin can carry junior cost, mezzanine is a later conversation. If senior already fails, stretch is not the remedy.
How is equity treated on each stack?
7(a) has a published injection. Five points of cash and five points of full-standby paper is the split many files use. Ask the lender to confirm the live SOP. SOP 50 10 8 ended the folklore that a seller note can cover the entire injection.
ABL still needs equity. Availability is not a down payment. A large opening base can hide a thin check until month two, when ineligibles show up.
Mezzanine is not the injection. It sits above equity and below or beside other junior claims depending on the paper. A seller who rolls into a warrant-heavy stack is reading dilution, not “flexibility.”
How do inventory and WIP change availability?
The working-capital peg prices the close. The borrowing base tests liquidity after the wire. They are cousins, not twins.
WIP is a traveler and a percentage-of-completion guess. Liquidators do not love half-finished housings. ABL examiners haircut or exclude them. 7(a) still wants classes because the valuation and the peg do. Mezzanine providers who ignore WIP still inherit the true-up fight.
Customer-owned tools in the cage are not inventory. Quality-hold is not finished goods. Write the classes before anyone argues about a “standard” line.
Who typically sits in the buyer seat?
7(a) is the individual-operator product on most small plants. Census CBP 2023 counted 284,452 manufacturing establishments; 68.4% have fewer than 20 employees (Source: Census CBP). Many of those files never need a sponsored revolver.
ABL shows up on larger or lumpier books, and on files that missed the 7(a) box. IBBA Pulse Q1 2026 put 83% of deals over $5 million at three or more offers (Source: IBBA). Competition does not thicken thin AR.
Mezzanine shows up with sponsors and some searchers on lower-middle-market checks. Stanford’s 2024–25 search median of about $16 million at ~6.2x EBITDA on a ~25% margin company is that neighborhood, not a walk-in job shop (Source: Stanford GSB).
What does junior cost actually do to coverage?
A current-pay mezz coupon hits year-one DSCR. PIK accrues and still sits above equity. Call protection can make an early refinance expensive. Unitranche can wrap first-out and last-out into one facility; the borrower sees one payment. The lenders still argue if the file later defaults.
Do not compare a blog’s “SBA is cheaper” sentence to a conventional sheet you have not read. This site will not invent a prime-plus quote.
When does each product fail a manufacturer?
7(a) fails when enterprise value plus fees plus the peg miss the $5 million box, when the injection is folklore, or when affiliation blocks a sponsor wearing an individual hat.
ABL fails when eligible AR is thin, concentration exceeds the exhibit, or job-cost WIP was booked at quoted margin.
Mezzanine fails when senior already fails, when a 40% customer is the story, or when warrants are hidden until week nine. Stretch does not repair a missing down payment.
Who should choose SBA 7(a)?
Choose 7(a) when the buyer is an operator who can personally guarantee, the check fits the published box, and a 10% injection can be documented. Peel real estate and heavy iron onto 504 when occupancy fits. Do not choose 7(a) to shoehorn a certified $12 million file into a slogan.
Who should choose ABL?
Choose ABL when the book has quality receivables and countable inventory, earnings are lumpy or the check sits above the 7(a) box, and someone will write two exhibits — peg and base — before exclusivity. Do not choose ABL because a revolver sounded more “institutional” than a guaranteed loan.
Who should choose mezzanine?
Choose mezzanine only after senior is honestly maxed, margin can carry junior cost, and counsel will read warrants, PIK, and call protection before the letter. Do not choose mezzanine to hide a missing injection or a whale customer.
