Most guides about buying an online store end at the handshake. This one starts there. Between an accepted offer and money actually moving sits the closing sequence: a letter of intent, diligence, a purchase agreement, escrow, a transfer checklist, and a transition period. Deals that go wrong usually go wrong here, and almost always because someone ran the steps out of order.
The letter of intent: fixing the ground
The LOI is a short document, often two pages, and mostly non-binding. It states the price and what that price assumes, the deal structure including any holdback or seller financing in outline, a target closing date, and two clauses that genuinely bind: exclusivity and confidentiality.
Exclusivity, typically 30 to 90 days, takes the store off the market while you spend real effort checking it. That is the LOI's actual function, honest sequencing: neither side wastes weeks on a deal the other is still shopping.
For an online store, add one thing generic templates miss: diligence access. Spell out that you get read-only access to the store's order data and ad accounts for the diligence window, and that access ends if the deal dies. A seller who has agreed to sell but resists read-only access is telling you something, just not out loud. Better to hear it now than after the agreement is drafted.
Diligence, briefly
This series has a full due diligence checklist, so here is only the closing-context point: diligence findings are negotiating events, not deal enders. Revenue two percent under the claim is a price conversation. Revenue twenty percent under the claim is a different store than the one you offered on. Surface everything before the purchase agreement is signed, because the same discovery costs a renegotiation now and a dispute later.
On a verified listing much of this compresses: the revenue reconciliation already happened before the store was listed, and your diligence spends its time on the questions automation cannot answer, suppliers, operations, and whether this is a business you actually want to run. If you want the checking done professionally on a store from any venue, a fixed-fee diligence report reads the raw data for you. And if the store you are buying is a dropshipping business, the dropshipping guide in this series adds the supplier-side steps.
The asset purchase agreement
The APA is the binding contract. Four sections do most of the work.
The asset schedule. The list of exactly what transfers: store account, domain and registrar access, ad accounts with their pixels, the email platform and its list, content and product data, social accounts, supplier agreements. This page decides what you own next month. Generic templates written for offline businesses routinely omit half of it, and if the schedule does not name an asset, the asset does not transfer. Read it twice.
Payment mechanics. The price, the escrow arrangement, and any holdback: how much stays back, for how long, and released on what checkable conditions. Holdbacks in online-business deals commonly run 10 to 25 percent for a year or two when used at all; verified numbers shrink both the size and the need.
Representations and warranties. Where the seller stands behind what was claimed: that the financials shared are true, the assets are owned and transferable, and there are no undisclosed problems. If a claim mattered to your price, it belongs here in writing.
Transition support. The hours, the channels, and the end date of the seller's help after closing, usually 30 to 90 days. Scope it now; open-ended support sours every deal it touches.
Put counsel on the agreement in proportion to deal size. And if the deal runs through a platform where both sides signed deal terms at offer time, the agreement builds on ground already agreed instead of starting blank.
Escrow: the step that protects every other step
The rule is simple and absolute: escrow is funded in full before any asset moves. The money sits with a neutral provider, the transfer happens, you confirm, the funds release. Neither side can end up holding both the money and the store, which is the entire failure mode escrow exists to remove.
The exact release conditions should be published, not implied: full funding, signed agreement, every critical asset handed over and confirmed. How escrow works end to end has its own answer; the closing-context rule is to read the conditions before you fund, agree the fee split in writing, and treat any suggestion to close outside escrow, from either side, as the deal-ending event it is. The discount a direct wire offers you is precisely the scam's margin.
The transfer, in order
Assets move in a sequence, each step ticked off a shared checklist. The store owner role first: a quick admin change that makes you the owner while the seller stays on temporarily as scoped staff for the transition. The domain next, with DNS checked so the storefront never drops. Payment processing re-anchors rather than transfers: you connect your own processor and payout account, the seller's banking comes off the same day, and you plan for the short cash-flow gap while your processing spins up.
Then the long tail that stumbling deals forget: ad accounts with their learning history, the email list with its privacy obligations, supplier portal logins, social accounts, app subscriptions. Every asset missing on day one costs you revenue and the seller goodwill.
When the checklist is done, you confirm the handover: admin access works, payouts flow to you, campaigns run. That confirmation is what releases escrow. The fee comes out, the seller is paid, any holdback stays back on its schedule.
After the release
The transition period starts when the money moves, not before. Use it on what was never documented: why the winning ads win, which supplier contact answers, what the seasonal rhythm looks like. If something material surfaces in the first weeks, raise it through the escrow inspection window if one is running, then through the agreement's representations, in that order, with the deal record as your evidence. The security model behind that record, read-only connections, gated unlocks, and an append-only log, is what makes the evidence worth having.
Most deals never need that paragraph. The ones that do are almost always deals where the numbers were claimed, not proven. It is the quiet argument for starting from a verified listing: the closing sequence above protects the transaction, but verification protects the price.
