Manufacturing M&A
Data room for selling a manufacturing business
ClosingVault is a data room for selling a manufacturing company, for any lower-middle-market deal up to $50 million. The seller drops in equipment lists, maintenance logs, customer contracts and quality records as they turn up, and each file is read, filed to the checklist item it answers and ticked off, so the broker chases only what’s missing.

What do buyers of a manufacturing company ask for in diligence?
Beyond three years of financials and tax returns, a manufacturing buyer wants to understand the plant: what the equipment is, what shape it’s in, who buys the output and what it costs to make.
-
Equipment list and fixed-asset schedule
Every machine with make, model, year and condition, tied to the fixed-asset and depreciation schedule, so the buyer can tell owned from leased and plan the capital spending ahead.
-
Maintenance and repair records
Preventive-maintenance logs and major repair invoices, which show whether the machines will keep running after closing or need replacing soon.
-
Customer concentration and contracts
Sales by customer over several years and the top customer agreements, with any supply or pricing terms, because a plant that ships most of its output to a few accounts is priced on those accounts.
-
Inventory and costing
Inventory counts and valuation across raw materials, work in process and finished goods, plus how standard costs are built and how often they are updated.
-
Quality records
Quality-system certificates, audit reports, customer scorecards and the history of returns and warranty claims.
-
Suppliers and single-source inputs
Key supplier agreements and any input that comes from one source, so the buyer can see what a supply disruption would cost.
-
Facility, permits and safety
The plant lease or deed, environmental and operating permits, safety logs and inspection reports.
Where does a manufacturing sale slow down in diligence?
Usually in the plant files. Maintenance history lives in a binder or a shop-floor system, equipment titles and leases are scattered, and the costing sits in someone’s spreadsheet. A buyer’s quality-of-earnings team will tie the inventory count to the books, and an equipment appraiser will walk the floor with the asset list in hand; when the two don’t match, the questions pile up.
Owner dependence is the other common snag. If the owner is the one who knows every customer’s buyer and every machine’s quirks, the buyer wants to see the people and procedures that carry that knowledge: the organizational chart, the standard operating procedures and the key employee agreements.
How does ClosingVault handle a manufacturing sale?
The plant keeps running while the room fills itself.
How fast can I set up a room for a manufacturing deal?
About 3 minutes with the standard checklist. It already asks for the Fixed Asset & Depreciation Schedule, the Inventory Valuation Report, Equipment Leases, the Top 10 Customer Contracts, the Top 10 Supplier & Vendor Contracts, Environmental & Health Permits and the Workplace Safety Manual. Add the rest of your plant requests by uploading your own Excel list, then release the checklist to the seller phase by phase. From there it’s fully customizable for any lower-middle-market deal up to $50 million: phases and dates, who can download, and when each buyer’s access ends. The free due diligence checklist is the same standard checklist, as an Excel download.
What does it cost?
Plans start at $79 a month, billed yearly (founding price). The firm that opens the room pays. Invited buyers, sellers, owners and their teams are always free and unlimited. Every plan and price, or see ClosingVault next to seven low-cost data rooms, step by step.
Manufacturing data room questions
I own a $14 million machine shop and a private equity buyer wants our equipment
list and maintenance records in two weeks. Can my plant manager upload straight
from the shop floor?
Yes. Your team works in the seller portal with your access and can upload scans and phone photos as they find them; each file is read and filed to the checklist item it answers. Your team never binds the sale: only the owners decide an LOI.
I’m a broker selling a family-owned fabrication company with four siblings as
owners. Who signs off on the LOI?
The owners, by ownership. The room admin enters each sibling with their share of the company, and an LOI is accepted, countered or declined only when owners holding more than half of the company approve.
I’m selling my plant to a competitor and don’t want them walking off with our
customer pricing. Can I limit what they get?
Yes. You decide person by person who may download; everyone else reads in a viewer stamped with their name and the time, with printing and copying suppressed. The room admin can also hide any single document from buyers in one click.
Our maintenance records are handwritten logs and phone photos of the shop
whiteboard. Will they get filed?
Yes. Scanned pages and images are read with OCR on ClosingVault’s own servers and filed by what is on the page. A file that can’t be read is flagged and the seller is asked for a readable copy.
I’m the buyer’s quality-of-earnings analyst on a manufacturing deal. Can I pull
every inventory valuation report the seller uploaded?
Yes. Ask the Data Room for “inventory valuation reports, every year” and it returns the documents themselves, filed and dated, from the documents you have access to.
Our equipment loan statements show full account numbers. Will buyers see them?
No. Account numbers on bank, card and loan statements are removed automatically, keeping the last four digits, and the values are taken out of the file, not just covered.
