A buyer looking at your store cannot see the work you did. They can only see the numbers, and they will believe exactly as much of them as you can prove. Preparation is not staging your store to look good. It is doing the reconciliation work now so there is nothing left for a buyer to discover later, at a discount, on their schedule instead of yours.
This is the order that work happens in, and it is the long version of the short checklist in how do I prepare my Shopify store for sale. Start 90 to 180 days before you plan to list. Less than that and you are compressing a year's worth of accounting into a sprint, and it shows.
Why preparation moves the multiple
Every ecom store sells on a multiple of SDE, roughly 2.2x to 3.2x annual SDE for verified stores, with strong brands pushing toward 4.5x. That range is not fixed per store. It moves based on how much of your story a buyer has to take on faith.
A claimed number costs you nothing to write down and costs a buyer everything to believe. So they do not believe it, not fully, and the gap between what you claim and what you can show up gets priced as risk. Every number you can prove holds your multiple where it should be. Every number you cannot invites a discount, and sometimes a walked deal. Preparation is the work of turning claims into proof before anyone asks, which is a different and much better negotiating position than scrambling to answer once someone already has. The valuation calculator shows roughly where your multiple lands once the numbers behind it are clean.
Separate personal and business finances
Start here because everything else depends on it. If your business account also covers your phone bill, your gym membership, or a family trip you called a "research trip", your P&L is not a P&L. It is a mix of business performance and your personal life, and no buyer can untangle that from the outside.
Open a dedicated business account if you have not already. Move every recurring personal charge off it. Going forward, treat the line between the two accounts as absolute, not a suggestion. This single change is what makes SDE calculable at all: SDE is net profit plus your salary plus personal expenses run through the business, and that add-back only works if you know exactly what those expenses were. A messy account forces a buyer to estimate, and an estimate they make on your behalf is never generous.
Reconcile ad accounts against your books
Pull your Meta and Google ad account spend for the last twelve months. Pull the matching line items from your accounting software. They should agree, month by month, to the dollar. If they do not, find out why before a buyer does.
Mismatches usually come from one of three places: spend booked in the wrong month, a card that also ran non-ad charges, or a campaign that ran on a personal card and never made it into the books at all. None of these are fraud. All of them read as sloppy at best, and a buyer who finds one unreconciled line starts wondering how many more exist that they have not found yet. That wondering is where discounts come from.
The fix is mechanical, not clever: build a simple monthly table, ad platform spend in one column, books spend in the other, and chase every gap until it closes. Do this for every channel you spend on, not just your biggest one.
Document supplier agreements and what actually transfers
A buyer is not just buying your revenue. They are buying your ability to keep fulfilling orders after you leave, and that depends entirely on suppliers most buyers never see until diligence.
For every supplier, write down the terms you have (pricing, minimum order quantities, payment terms), how long you have worked with them, and whether the relationship is with your business or with you personally. Some supplier terms are tied to a personal relationship or credit history and will not automatically transfer to a new owner. That is fine, buyers plan around it, but only if you say so upfront. Finding it out during diligence reads as something you hid.
If you have exclusive terms, better-than-list pricing, or a supplier who will only deal with you by name, write down exactly what would need to happen for that to survive a change of ownership: an introduction call, a new contract, a trial order. A buyer who knows the plan can price around it. A buyer who does not know the risk exists prices the worst case.
Write down owner hours and processes
Every store runs on some amount of the owner's time that never shows up in the P&L. Sourcing calls, customer service escalations, the weekly inventory check you do from memory. If that time is invisible, a buyer either assumes the business runs itself, which is wrong and sets them up to be blindsided, or assumes the worst and underprices the SDE, which costs you money you actually earned.
Track your actual hours for a few weeks: what you do, how often, how long it takes. Then, for anything that repeats, write it down as a process a stranger could follow. This makes the handover real instead of theoretical, which buyers pay for, and shows you which hours are actually replaceable with a system or a hire.
If you paid yourself a salary and plan to add it back into SDE, this documentation is also your defense of that add-back. A buyer replacing sixty hours a week of your personal expertise will subtract a real cost from the multiple; a buyer replacing ten hours of documented, delegable tasks will not.
Clean up traffic experiments
Look at your traffic sources for the last year. If there is a channel test that ran for six weeks and never again, a viral post that spiked a month of sessions, or an influencer push that never repeated, flag it. None of these are bad. They are just noise if a buyer reads them as your normal traffic mix instead of what they were: one-off events.
Buyers price traffic mix directly. Mostly organic traffic adds to the multiple because it is an asset that transfers with the business. Mostly paid traffic subtracts, because it is a bill that transfers instead. A short spike from a test you ran once can overstate a channel you cannot repeat, or bury a channel that is actually stable. Label the experiments, note what happened, and let the underlying pattern show through clean.
Build twelve months of consistent P&L
This is the step everything else feeds into. A buyer wants to see a full year of monthly statements, built the same way every month: same categories, same method for recognizing revenue, same treatment of returns and refunds. Twelve consistent months let a buyer see a trend, not a snapshot. A trend is what they are actually buying, because they own next year, not last year.
Inconsistent categorization between months turns a five-minute review into a week of back-and-forth. If January calls something "marketing" and August calls the same charge "operations", a buyer has to reconcile your own inconsistency before they can even evaluate the business. Pick a chart of accounts and stick to it for the full period you are presenting.
A worked example
Say you run a home goods store and plan to list in six months. Today, your personal Amazon subscription and a chunk of your car payment run through the business account. Your Meta spend is booked to the card statement date instead of the charge date, so it is off by a few days most months. You have a great pricing deal with your main supplier, but it exists because you have known the owner for eight years and there is no contract, just a handshake. You do 15 hours a week of sourcing and customer service that nobody has ever written down. And last spring you ran a two week TikTok influencer test that briefly doubled your traffic and then vanished.
Over the next six months: the personal charges come off the business account this month. The ad reconciliation gets fixed by categorizing correctly going forward and cleaning the last twelve months retroactively. You write a one-page memo on the supplier relationship, including that a new owner would need an introduction call and probably a written agreement. You spend three weeks logging your actual hours, then turn the recurring ones into a simple SOP document. You add a note to your traffic report flagging the TikTok spike as a one-off test, not a channel.
None of this changes what the business actually earns. All of it changes whether a buyer believes what it earns, and that belief is most of what sets your multiple. For the underlying math on how SDE and multiple combine into a number, see how to value a Shopify store.
Make it provable, not just presentable
A cleaned-up story is not the same as a provable one. The difference is whether your numbers can be checked against a source that is not you. On Kairos, that source is your real Shopify order data: revenue, order counts, and trends are verified read-only against the store itself, before any buyer sees a number. Listing is free, and there is no charge unless a deal actually closes.
If you want a documented answer for every open question above, before you take a listing live, the Kairos due diligence service is a paid, human review that produces a report within 5 working days, and it works whether your store lives on Shopify or another platform entirely. It is built for exactly the gap this guide describes: the space between what you believe about your business and what a stranger can independently confirm.
Kairos is pre-launch, with verified inventory opening and the waitlist getting first access. When your books, suppliers, and process notes are ready, selling on Kairos starts with that same verification, against your real order data, before any buyer ever sees a claim you have not already checked yourself.
What to do with six months, and what to do with six weeks
If you have the full 90 to 180 days, work the list in order: finances first, then reconciliation, then documentation, then a full clean year of P&L. Each step makes the next one easier, and rushing the first one undermines everything after it.
If you only have a few weeks, do not compress all of it. Start with the finance separation and the ad reconciliation, the two things a buyer checks first and the two most likely to stall a deal outright. Supplier documentation and the hours log matter, but a buyer can work with "we are finishing that" more easily than a P&L that does not reconcile.
Either way, the destination is the same: a store where every number in the listing points back to something a buyer can check themselves. That is what preparation actually buys you. Not a better story. A story nobody has to take your word for.
