Buy a Machine Shop in Boston, MA
The Boston Machine Shop Market
Boston's machine shop market is shaped by its proximity to defense contractors, biomedical device manufacturers, semiconductor firms, and aerospace primes clustered across Route 128 and the 495 corridor.
That customer concentration is a double-edged sword. Shops servicing Raytheon, Boston Scientific, or Analog Devices often have strong recurring revenue. But if a single customer represents more than 30% of revenue, that's a structural risk in any acquisition.
Nationally, there are roughly 34 active machine shop listings in the pipeline. Boston-area shops skew toward the higher end of that range, reflecting the technical complexity of the work and the cost of maintaining precision equipment in a high-cost-of-living metro.
Expect asking prices to track 3x to 4x annual cash flow for most deals. The national average sits at 3.7x, and Boston is not going to be cheaper than that.
Deal Economics for a Boston Machine Shop
The median asking price for a machine shop acquisition is $995,000 with median annual cash flow of approximately $287,000, implying a 3.7x multiple. According to Regalis Capital's deal team, most machine shop acquisitions in this range support solid debt service coverage when structured with a full-standby seller note at 0% interest.
Here is what the deal math looks like on a $995,000 acquisition at median cash flow:
- Asking price: $995,000
- Annual cash flow: $287,000
- Implied multiple: 3.5x (roughly)
- SBA loan (80%): $796,000
- Seller note (15%, full standby, 0%): $149,250
- Buyer equity injection (5% cash): $49,750
- Approximate annual debt service: ~$100,000 (SBA at ~10.5%, 10-year term)
- DSCR: approximately 2.9x
That is a clean deal. The 2.9x DSCR gives you meaningful cushion, and at 3.5x cash flow the pricing is well inside the SBA sweet spot.
Note that the 5% seller note on full standby counts as equity toward the SBA's 10% injection requirement. Full standby means no payments on the seller note during the SBA loan term. Regalis Capital achieves this structure on over 90% of deals.
These are estimates based on national market data. Actual terms depend on individual qualification, lender, and the specific deal.
If you are using SDE figures from a broker package, discount them 15% to 50% before running your own DSCR math. SDE is broker-friendly and almost always overstates what a working owner-operator will actually take home.
What to Look for in a Boston Machine Shop
When evaluating a machine shop acquisition, the three financial documents that matter most are job order history, equipment maintenance logs, and customer concentration by revenue. A shop where one customer accounts for more than 25% to 30% of billings carries meaningful concentration risk that should be priced into the deal or mitigated through an earnout.
Customer diversification. As noted above, Boston-area shops often have a handful of large industrial or defense customers. Run the revenue by customer for the last three years. Flag anything above 25%.
Equipment condition and age. CNC mills, lathes, and EDM machines are capital-intensive. A shop with aging equipment that needs replacement in years two through four is a different acquisition than one with a recent capex cycle. Get an independent equipment appraisal, not just the owner's schedule.
Owner dependency. If the owner is the lead programmer, the key account contact, and the shop foreman, you have a transition risk problem. Ask specifically what the owner's day-to-day looks like and whether key employees are staying.
Backlog and pipeline. A healthy machine shop has a visible backlog of 30 to 90 days. If the owner cannot show you a forward order book, that is a flag.
Certifications. AS9100 (aerospace), ISO 9001, or ITAR registration can meaningfully expand the customer base you inherit. Shops with active certifications command premium multiples and tend to have more defensible revenue.
Local Considerations in Boston
Labor is tight and expensive. Skilled machinists in the Boston metro earn $28 to $45 per hour depending on experience level and specialization. If the shop is running lean, assume you will need to budget for wage increases to retain staff post-close.
Real estate matters here more than in most markets. Boston industrial space runs $12 to $20 per square foot annually for light manufacturing. If the seller owns the building and is willing to do a sale-leaseback, structure the lease term to match your SBA loan length. If the building is not included, verify your lease rights carry forward and negotiate a long-term option.
The Massachusetts qualified small business stock rules do not apply to most machine shop acquisitions, but the state's 5% corporate income tax and 8.0% short-term capital gains rate should be factored into your hold period planning if you intend to sell within five years.
Frequently Asked Questions
How much does it cost to buy a machine shop in Boston?
Asking prices range from under $100,000 for distressed or micro-shop listings to over $8.9 million for larger operations with proprietary equipment or defense contracts. The national median sits at $995,000. Boston-area shops with aerospace or medical device customers typically price at the higher end of the 3x to 4x cash flow range.
Can I use SBA financing to buy a machine shop in Massachusetts?
Yes. Machine shop acquisitions are well-suited to SBA 7(a) loans. The equity injection requirement is 10% of the acquisition price, typically structured as 5% buyer cash plus a 5% seller note on full standby at 0% interest. On a $995,000 deal, that means roughly $49,750 in out-of-pocket cash from the buyer.
What cash flow should I expect after debt service on a machine shop?
On a $995,000 acquisition with $287,000 in annual cash flow and roughly $100,000 in annual SBA debt service, you are looking at approximately $187,000 in pre-tax cash flow. That assumes the seller note is on full standby with no payments due during the loan term, which is the standard Regalis Capital structure.
What is the biggest risk in buying a machine shop?
Customer concentration is the most common structural risk. A shop where 40% or more of revenue comes from one customer is effectively a subcontractor, not an independent business. Pricing risk, workforce dependency, and deferred equipment maintenance are close behind. All three show up clearly in a competent quality of earnings review.
How long does it take to close a machine shop acquisition in Boston?
A typical SBA-financed acquisition takes 60 to 120 days from signed letter of intent to close. Machine shops with significant equipment schedules or government contracts may take longer due to third-party appraisals and any required contract novations. Working with an experienced acquisition advisor compresses this timeline.
