Based on hundreds of real buyer-seller diligence conversations we’ve helped happen on Rejigg, these are the electronics manufacturing questions that actually move price: whether margins hold up through BOM (Bill of Materials) swings, what yield looks like on real builds, how often ECOs (Engineering Change Orders) hit mid-run, and how your shop handles audits.
Each topic below comes from real buyer-seller conversations. Here's what they ask, what they're really evaluating, and how to prepare.
Margin Truth
Buyers want to know if your gross margin shows up on real builds or if it gets propped up by unbilled engineering time, overtime, and eating expedite costs. They are also looking for hidden cross-subsidies between programs and whether one ugly build can wipe out a month of profit.
How to prepare
Great Answer
We pulled 10 builds across prototype, steady production, and end-of-life. For each one, we have quoted vs actual margin with rework hours, scrap dollars, expedite freight, and any RMAs tied back to the job. Steady production averages 28–32% gross margin, and when shortages force broker buys, we either pass the premium through under our terms or get written approval before we ship.
Okay
We can walk you through a few recent jobs and show where margin moved. We track scrap and rework, but it isn’t consistently tied back to each job.
Gives Pause
Our gross margin is about X% overall, and it’s been stable. We don’t break out rework, expediting, or returns by job.

BOM Risk
Buyers want to see a repeatable way you protect margin when component pricing and availability move. They’re also trying to understand how often shortages, alternates, and last-minute broker buys turn into surprise losses or late shipments.
How to prepare
Great Answer
On our top five programs, we keep a parts-risk list with long-lead and single-source components and the status of approved alternates. When BOM cost moves, we re-quote or issue a written change approval tied to actual procurement cost. Here are three recent builds where allocation forced alternates or broker buys, and we passed through the premium with documented customer approval.
Okay
We’ve dealt with shortages and usually work it out with the customer. We can share a couple examples, but the process isn’t consistent across every program.
Gives Pause
We try not to raise prices, and we do whatever we need to do to ship. Sometimes we buy from brokers and eat it.
How Rejigg helps: Rejigg lets you stage BOM-sensitive examples so only vetted, NDA-signed buyers can see program details and terms. Learn more in the guide
Yield Control
In electronics manufacturing, quality shows up directly in margin and delivery. Buyers are looking for measured yield, clear defect ownership, and proof that fixes stick instead of being solved by a few people firefighting on overtime.
How to prepare
Great Answer
We track first-pass yield by line and product family. On our two biggest families, we run 96–98% first-pass at functional test, and the main defects are solder opens on one package type, plus occasional programming failures. Here are two corrective actions we ran, what changed on the line, and the trend over the next three lots.
Okay
We have a good sense of yield, and we track defects, but it isn’t consistently broken out by program. We can pull detail for the biggest jobs.
Gives Pause
Our quality is good, and customers don’t complain much. We don’t track yield or rework formally.
How Rejigg helps: Rejigg’s data room keeps yield reports, defect logs, and corrective actions organized so diligence feels like confirmation. Learn more in the guide
ECO Discipline
Buyers want to see real revision control in a busy shop. They’re checking whether you can lock a build at kitting, prevent old-rev material from sneaking in, and avoid wrong-rev builds that lead to chargebacks or warranty pain. They also want to know if ECO work gets priced and documented, especially when the customer changes scope midstream.
How to prepare
Great Answer
We locked the revision at kitting, and only released programming files and travelers were allowed to run on the line. When a change hit mid-build, we documented WIP disposition and billed for incremental labor or scrap when the change was customer-driven.
Okay
We have a process for changes and usually keep revisions straight. Some steps are informal, but the team knows how to make it work.
Gives Pause
We build from the latest email, and engineering tells the line what changed. Sometimes the floor figures it out as they go.
How Rejigg helps: Rejigg lets you store your ECO workflow and a few clean examples in one secure place so buyers can follow the story quickly. Learn more in the guide
NPI Handoff
NPI is where electronics shops either prove they have a system or bleed money through first-article failures, missing test coverage, and constant changes. Buyers want to see that prototypes turn into routings, fixtures, and test procedures production can run. They’ll also look closely at whether engineering time is tracked and billed when scope expands.
How to prepare
Great Answer
We run NPI in stages: prototype, pilot, then production release. Before pilot, we require a controlled BOM, gerbers, test requirements, and a defined revision. We charge for DFM (Design for Manufacturability) and test development, track engineering hours to the job, and issue written change approvals when scope expands. Here are two NPIs that converted into production and the timeline and margin at each stage.
Okay
We do a lot of NPI, and it’s a strength. We charge for some engineering, but it isn’t consistent across every program.
Gives Pause
NPI is messy everywhere. We do what it takes to get it out the door and make it up in production later.
How Rejigg helps: Rejigg helps you share NPI examples, quote templates, and handoff documents in stages as a buyer gets more serious. Learn more in the guide
Program Mix
Buyers look at program concentration because one SKU can consume your best line time, fixtures, and engineering attention. They’re trying to price lifecycle risk like redesigns, dual-sourcing, insourcing, or a region change that drops utilization fast, even if the customer relationship stays fine.
How to prepare
Great Answer
Our top 10 programs drive 78% of revenue, and we track them by lifecycle stage. The largest program is 22% of revenue and is in sustainment with a multi-year release cadence. We’re an approved vendor; we own key fixtures and programming steps, and we supported two revisions without a supplier change. If it slows, we can flex into similar industrial controls work and historically onboard replacement programs in 60–90 days.
Okay
We know our biggest customers and which products they buy. We can explain which ones feel stable, but we haven’t mapped it cleanly by SKU and lifecycle.
Gives Pause
We’re not concentrated because no single customer is over X%. We don’t track it by program.
How Rejigg helps: Rejigg helps you show program concentration clearly, with de-identified summaries early and full detail later under NDA. Learn more in the guide
Build Data
Buyers treat build data as a core asset because it’s what makes an SMT and assembly shop repeatable. They’ll look for controlled pick-and-place programs, test procedures, work instructions, and fixture documentation. They also want to see basic continuity and security so the business doesn’t fall apart if one programmer leaves.
How to prepare
Great Answer
All SMT programs, test procedures, and released work instructions live in a controlled repository with access rules and backups. Only designated engineers can release a revision to production, and the traveler references the released file version. Our SMT programmer and test engineer each have trained backups, and we can show the last two coverage rotations where someone else released work successfully.
Okay
We keep files on a shared drive and back them up. Most changes go through engineering, but the controls are not fully formal.
Gives Pause
Our programmer has everything on his laptop. If you need an older revision, we dig through emails.
How Rejigg helps: Rejigg lets you share process documentation and role ownership with vetted buyers while keeping sensitive customer files permissioned. Learn more in the guide
Inventory Risk
Inventory is a common closing fight in electronics because ECOs, cancels, and forecast drops can create dead stock fast. Buyers want to see you separate usable material from excess and obsolete. They’ll also look at customer terms that spell out who owns last-time-buys and forecast-driven material.
How to prepare
Great Answer
We review excess and obsolete quarterly with purchasing and engineering. Here is our inventory aging report with a disposition plan for each major item, including customer bill-back where terms allow and broker liquidation when that is the best outcome. Consigned inventory is tracked separately in the system, physically segregated, and reconciled by customer and program.
Okay
We keep an eye on obsolete material and write off some each year. We can pull an aging report, but it’s not always tagged with a clear disposition plan.
Gives Pause
Inventory is inventory. We don’t track obsolescence separately, and we’ll deal with it at closing.
How Rejigg helps: Rejigg’s data room makes it easy to share inventory aging, consignment summaries, and disposition notes without version mix-ups during diligence. Learn more in the guide
Capacity Reality
Buyers underwrite effective capacity, not the nameplate speed on an SMT line. They want to know where jobs really queue up, which is often kitting, inspection, conformal coat, or test. They’ll also ask what it takes to grow without breaking on-time delivery and quality.
How to prepare
Great Answer
Our SMT line is not the constraint. Functional test is, and we can show it in schedule history and queue time. Uptime on our selective solder machine is tracked with planned maintenance; we have a service contract, and we use a qualified overflow partner for spikes. To grow 20%, we need a second test station and two additional fixtures for the top families, not a new SMT line.
Okay
We have room to grow, and we know the general bottlenecks. We haven’t quantified it tightly, but we can explain where work backs up.
Gives Pause
We have plenty of capacity. We could double revenue with the same equipment if we just had more orders.

Our 6-step owner's guide covers everything from deciding to sell through post-sale transition.
What is an electronics manufacturing business typically worth?
Electronics manufacturing and EMS (Electronics Manufacturing Services) shops usually trade based on cash flow and how predictable the margin is when the BOM moves, yields fluctuate, and engineering changes hit mid-build. Buyers pay more when program profitability is provable and the shop can run without one hero estimator, programmer, or quality lead. For a starting point, use Rejigg’s free valuation calculator, then validate it with quote-to-ship job history by program and customer risk.
Do I need a broker to sell my electronics manufacturing company?
No. You don’t need a broker to sell an electronics manufacturing business, and you shouldn’t give up 5–10% of the sale price for work you can run yourself. Rejigg gives you pre-vetted buyers, digital NDAs, a secure data room, direct messaging, and an offer tracker so you can control the process end-to-end. Start with the preparation guide and build your diligence pack before you list.
Can a buyer use an SBA loan to buy an EMS shop?
Sometimes. SBA lenders want clean, provable cash flow and a business that can transfer without the owner personally doing all the quoting, programming releases, and customer firefighting. They’ll also want clear financial statements and a documented list of owner expenses that truly won’t continue after the sale. Rejigg’s SBA loan calculator helps you and a buyer model payments and buying power before negotiating price and seller financing.
How long does it take to sell an electronics manufacturing business?
Most electronics manufacturing deals take about 4–9 months from “ready to list” to closing, mainly because buyers need operational proof. Expect requests for job history, yield and rework evidence, parts-risk exposure, audit posture, and customer terms, plus a site visit. You can speed this up by building a staged diligence packet ahead of time and controlling versions in Rejigg’s data room and deal tracker. See due diligence and closing.
What financial statements do buyers ask for in electronics manufacturing due diligence?
Expect profit and loss statements, balance sheets, tax returns, and job-level reporting that ties margin to real builds. In electronics manufacturing, buyers often push for program summaries that show material, labor, and test costs, plus where rework, scrap, expediting, and RMAs land in your accounts. If your books are in QuickBooks, Rejigg’s QuickBooks integration helps import and organize financials into a buyer-ready package inside the Rejigg platform.
What are typical add-backs for an EMS business sale?
Typical add-backs include owner pay above market, one-time legal or consulting bills, personal expenses run through the company, and truly non-recurring repairs or relocation costs. In EMS, buyers get skeptical when “add-backs” are really recurring costs like expediting, rework labor, or warranty work that happens every month. Build a simple add-back schedule with receipts and a short explanation for each line so diligence stays clean.
How do buyers handle working capital in an electronics manufacturing acquisition?
Working capital is the cash tied up in day-to-day operations, mostly accounts receivable, inventory, and accounts payable. In EMS, it gets touchy because turnkey builds, last-time-buys, and forecast changes can inflate inventory fast. Many deals set a “normal” working capital target, then adjust the price based on what is delivered at closing. Keep clean inventory aging and AR reports in Rejigg’s data room to avoid last-week surprises.
How are customer contracts and purchase orders treated in EMS deals?
Many EMS relationships run on purchase orders and forecasts, not long-term contracts, so buyers look for practical stickiness. That usually means approved vendor status, audit history, and switching friction like fixtures, test coverage, and production history. They will also review your terms around price changes, alternates, customer-supplied material, and obsolescence ownership. Keep your current terms and a few real examples organized so you can share detail only after NDAs are signed in Rejigg.
Will my OEM customers find out I’m selling?
Not unless you choose to tell them early. Most sellers use staged disclosure: share de-identified program summaries and operating proof first, then reveal customer names and BOM-level detail only with serious buyers. Rejigg helps because buyers are pre-vetted and sign NDAs digitally before seeing sensitive information, and you control exactly who sees what in the data room. Use finding buyers to plan the rollout.
Do I need ISO certification to sell an electronics manufacturing business?
Not always. Buyers mainly want proof that your quality system matches what your customers expect, especially for audit-heavy work. Expect requests for audit results, traceability examples, calibration records, ESD (Electrostatic Discharge) controls, and corrective actions. Missing a certificate can be workable if the evidence is strong. Deals slow down when the story sounds good but the proof is thin. Keep your evidence organized so you can respond fast using Rejigg’s due diligence checklist.
How do buyers value equipment in an SMT and electronics assembly shop?
Most buyers treat equipment as part of the operating business, not as a separate auction, unless the company is distressed or unusually asset-heavy. They focus on which machines actually constrain throughput, how often they go down, and how expensive that downtime is in missed shipments. Expect questions about age, service history, feeder and nozzle condition, spare parts, and redundancy for steps like AOI (Automated Optical Inspection), selective solder, and conformal coat. A buyer-ready equipment list flags bottlenecks and single points of failure.
What’s the difference between an asset sale and a stock sale for an EMS company?
In an asset sale, the buyer purchases selected assets and takes on selected liabilities. In a stock sale, the buyer purchases the legal entity and inherits what is inside it. EMS sellers often like stock sales for simplicity, while buyers often push for asset sales to limit exposure to historical quality issues, warranty obligations, and tax problems. Your accountant and attorney should model after-tax outcomes. Bring a clear picture of RMAs, open corrective actions, and customer claims so buyers don’t assume the worst.
How do earnouts work in electronics manufacturing deals?
An earnout pays part of the price later if the business hits agreed results, often over 12–36 months. In EMS, earnouts can get tricky because margins move with BOM costs, yield, and customer schedule changes. If you accept one, define the metric and the rules clearly, including how purchasing premiums, rework booking, and staffing changes get treated. Rejigg’s offer comparison dashboard helps you line up earnout terms next to price and financing so you can see the real trade-offs.
How does seller financing usually show up in an EMS acquisition?
Seller financing is when you take a note and get paid over time, usually to support bank financing or bridge a valuation gap. In EMS, buyers often ask for it when they see risk around program concentration, re-audits, or inventory exposure from last-time-buys. If you offer it, get specific on down payment, interest rate, repayment schedule, and what happens if a major program drops. Rejigg’s deal tracker keeps those terms explicit instead of buried in email threads.
What are common tax issues when selling an electronics manufacturing business?
The biggest tax drivers are deal structure, how equipment and inventory are treated, and how any transition or consulting payments are categorized. EMS shops can also have inventory write-offs and warranty reserves that complicate what “normal” profit looks like. Pull your tax advisor in early so you do not agree to a headline price that nets less than you expect. The negotiation guide helps you pressure-test terms beyond price.
How long should the owner stay after the sale in an electronics manufacturing business?
Many deals land in the 3–12-month range, but it depends on where the know-how lives. If the owner is the estimator, the key customer contact, and the escalation point for quality issues, buyers usually want a longer transition or a consulting arrangement. If quoting, programming release, and quality decisions already sit with a team, the handoff can be shorter. Plan roles and milestones up front using transition planning.
What happens to employees after an electronics manufacturing acquisition?
Most buyers want continuity because operators, process engineers, SMT programmers, and quality staff carry a lot of the real value. The risk is uncertainty causing key people to leave right when the buyer needs stability for audits and program continuity. Identify your critical roles and put a simple retention and communication plan in place. Rejigg helps you run a tighter, quieter process so fewer employees get pulled into rumors before you are ready.
What should I put in a buyer-ready data room for an EMS business?
A strong EMS data room includes quote-to-ship job proof, program summaries, inventory aging with excess and obsolete notes, customer terms around BOM changes and liability, and quality evidence like audit outcomes and traceability examples. Keep it staged so early buyers see de-identified summaries, then deeper BOM and customer detail later. Rejigg includes a built-in secure data room with permission controls so you can share the right depth at the right time.
