Buying a store: the inventory handover audit for buyers

The listing says the stationery shop on Mill Street comes with $61,200 of inventory at cost — 640 SKUs, a system export attached, numbers that look precise because they have cents after them (illustrative figures; this article runs the whole audit against them). Those units are about to become your cash, your tax basis, and your shelf, on the strength of a report the seller's own staff typed. The handover audit is how you turn that claim into a number you can defend: agree the count basis, pin down the valuation, price the open purchase orders, and measure the gap between their system and their shelves. The full checklist is below, and the worked example in the middle shows what these audits typically find.

Why the seller's stock number can't be your number

A seller's inventory report is an opening position, not a measurement. Three reasons it can't be taken at face value:

• The report reflects their system, not their shelf. Every operating store drifts: POs received short, POS sales keyed late, damaged goods never written off. The seller's own counts would show it — if any have been run recently.
• The valuation basis is theirs, not yours. "At cost" can mean last invoice cost, average cost, or a cost typed in 2022 and never updated. An at-retail valuation is worse: a $24.99 sticker is neither what the units cost nor what they'll clear at.
• The incentives point opposite ways. The seller prices the stock high, you want it low, and neither side is lying so much as both using a number that was never built for a sale.

None of this is a reason to walk away. It's a reason to count. Note the audit here is a different job from auditing stock you already own: when it's your own store, you have a drift history, a receiving log, and a count calendar to work from — the four-layer method in the Shopify inventory audit guide covers that situation. When the stock is someone else's, all three have to be rebuilt from the handover itself, which is what the checklist below does.

The four questions to settle before you count

• What is the count basis? Who counts (buyer, seller, or both), when (within days of closing, ideally), and blind — the counting team shouldn't see the system quantity while they count. Agree the dispute rule in advance: what happens when a counted number disagrees with the system by more than a threshold you both signed off on.
• What is the valuation basis? At cost is the norm for a stock purchase, and the agreement should say which cost: the seller's last invoice price per SKU, or prices you verify against recent invoices for the top sellers. Decide how damaged, expired, or obsolete units are valued — usually at zero, not at a hopeful discount.
• Which purchase orders transfer? Open POs with deposits paid and balances owed, inbound freight already on the water, and any stock sitting at suppliers on consignment or in for repair. Each one is either an asset you're buying or a liability you're assuming, and the agreement should list them by PO number.
• What shrink assumption comes baked in? System quantity minus counted quantity is shrink — theft, damage, record drift accumulated under the seller's operation. In a takeover that gap gets priced, not absorbed by default: in most asset deals the purchase price adjusts to the counted value, which shifts the shrink back to the seller.

A worked valuation, illustrative arithmetic

Here's the audit against the Mill Street numbers (illustrative throughout):

The arithmetic: your blind count of 640 SKUs values at $57,850 against the seller's $61,200 — a $3,350 gap, 5.5% of the claim. Revaluing 38 water-damaged units to zero removes another $1,140, landing counted value at $56,710 (61,200 − 3,350 − 1,140). Separately, the seller has a $14,400 notebook order in production with a $4,800 deposit already paid: either the deal excludes it and the seller unwinds it, or you assume it — $4,800 is already their spend, $9,600 comes due on your side when it ships (all illustrative).

Two things surprise first-time buyers. The gap is rarely dramatic SKU by SKU — it's a hundred small drifts adding up. And the PO commitments are often worth more than the shrink gap: a $4,800 deposit on goods you actually want is fine, while a $4,800 deposit on goods you'd never have ordered is a negotiation point.

The takeover audit checklist

Before you sign

• Get the stock report as a raw system export — SKU, quantity, unit cost, last receipt date — not a PDF summary
• Agree the valuation basis and the dispute threshold in writing, inside the purchase agreement
• Get the open-PO list with deposits paid, balances owed, and expected delivery dates
• Ask for the last two full counts and any shrink history; a year with no counts raises the price of trusting anything
• Confirm exclusions: damaged goods, the owner's personal stock, anything out at a supplier or in for repair

Count day

• Blind count, two-person teams, highest-value SKUs first
• Count the returns shelf, the damaged bin, and display units separately — they hide the biggest surprises
• Photograph anything questionable; photos settle disputes cheaply
• Reconcile against the system the same day, per SKU, with both parties present

At handover

• The signed count sheet becomes a schedule attached to the purchase agreement
• Rebuild unit costs in your own system — Shopify's cost-per-item field is what feeds its native profit reports, as of November 2026 (Shopify Help Center, accessed November 2026)
• Collect the supplier file: contacts, payment terms, order channel, and quoted lead times per supplier
• Get PO ownership in writing: which numbers you own, deposit amounts, delivery dates

First 30 days

• Audit the first five inbound deliveries against their POs — receiving habits come with the store
• Set your own count cadence; the methods live in our inventory counts guide
• Compute days of cover on the bestsellers you just inherited so the first reorder is yours, not the seller's leftover habit
• File the handover packet — count sheet, PO list, supplier file — where you can produce it later; retention specifics are in the inventory records compliance guide

Buying the stock vs buying the whole business

Structure changes what the audit can protect you from. In an asset purchase you're buying specific counted units, so pre-closing discrepancies become price adjustments and post-closing discoveries usually land on you — which is exactly why the count happens before closing. In a share purchase you inherit the company, records and all, and the SBA's guidance on buying an existing business (accessed November 2026) is blunt that reviewing the paperwork matters as much as reviewing the storefront. Tax-wise, the inventory you acquire becomes your opening inventory and feeds cost of goods sold on your first return, so the valuation basis you negotiate is also a tax input, not just a price lever (IRS Publication 334, Tax Guide for Small Business, accessed November 2026).

When the handover comes with a person

If the seller's operations manager is staying on through a transition month, that's a second handover with different mechanics — capturing the knowledge before an experienced person leaves is the template in the inventory manager handover guide. The stock audit and the knowledge handover fail in different ways, and one doesn't cover the other.

Common questions

Should inventory in a store acquisition be valued at cost or at retail? At cost, almost always. Retail value assumes every unit sells at full price, which no acquired inventory does; cost reflects what the units are actually worth as goods you now own. Nail down which cost — last invoice or verified invoice — and value damaged or obsolete stock at zero in the purchase agreement.

Who should count the inventory at handover, the buyer or the seller? Both, counting blind: your team counts without seeing the seller's system quantities, then you reconcile together the same day. A seller-only count produces the seller's number; a buyer-only count invites disputes. The signed, agreed count sheet should attach to the purchase agreement as a schedule.

What happens to open purchase orders when a store changes hands? Whatever the purchase agreement says — so make it say something. Each open PO is either excluded (seller cancels and unwinds deposits) or assumed by you, with deposit amounts and remaining balances listed by PO number. Unlisted inbound freight is a common post-closing fight; list it.

What is a shrink adjustment in an inventory handover? The gap between the seller's system quantity and your blind count: theft, damage, and record drift accumulated under their operation. In an asset purchase the price usually adjusts to the counted value, which prices that gap into the deal instead of leaving you to absorb it after closing.

Can I rely on the seller's inventory report instead of counting? No. The report is their system's opinion, shaped by their receiving habits and valuation choices — precisely the things you're trying to verify. Use it to plan the count and flag anomalies, but let the blind count and the agreed valuation basis set the number you pay on.

Next step

Do one thing today: request the stock report as a raw export and the open-PO list with deposits and balances. If either arrives as a summary PDF, ask again — the audit runs on raw records. Then, once you own the stock, compute days of cover on the ten bestsellers you inherited so your first buying decisions are built on your own numbers; the arithmetic is in the days of cover guide.
