How to value an ecommerce business in Australia

An Australian ecommerce business is valued the same way as any other trading business: as a multiple of normalised owner earnings — PEBITDA or SDE for an owner-run store, EBITDA for a larger managed one — not as a multiple of turnover. Whether stock on hand sits inside that price or is counted and paid for separately at settlement is a term of the contract, so check which one an asking price assumes. What differs online is what sets the multiple: where the traffic comes from, how concentrated the suppliers and sales channels are, and whether the domain licence, brand and customer data can actually be transferred to the buyer.

An online store is valued on the same arithmetic as a café or a plumbing business: normalised earnings multiplied by a multiple. business.gov.au sets out five common ways to put a value on a business — current market values, return on investment, business asset value, the cost of starting the business from scratch, and future profit — and for an open-market sale, an earnings multiple is the one buyers default to. What ecommerce changes is not the formula. It is which risks the buyer prices, and which assets they are actually buying.

Work out the earnings figure first

In Australia the owner-earnings measure is usually labelled PEBITDA — proprietor's earnings before interest, tax, depreciation and amortisation, meaning profit with the working owner's salary and owner-specific benefits added back. SDE, seller's discretionary earnings, is borrowed from American practice, circulates widely for online businesses, and covers close to the same ground. Either suits a smaller owner-run store, because it shows what a buyer working in the business would take home. EBITDA, with a real management wage left in the costs, is used for larger operations where the owner is not packing orders. Whichever applies, the figure has to be normalised: reported profit adjusted for one-off and personal items before anyone multiplies it.

Ecommerce normalisation has its own traps. An owner doing their own photography, copywriting, ad buying and customer service is contributing labour a buyer must pay someone to replace, and that cost belongs in the earnings figure. Ad spend cut back in the months before a sale lifts reported profit while draining the traffic that produced it — buyers reconstruct that, so sellers may as well do it first. One-off costs come out: a platform migration, a rebrand, a bulk stock buy-in.

Stock needs its own line. A contract can bundle stock on hand into the price, or count it at settlement and pay for it on top — which is why an asking price and a settlement figure can differ, and why the first question to ask of any asking price is which arrangement it assumes.

What sets the multiple online

A multiple is a risk judgement: how confident the buyer is that today's earnings will still be there next year without the seller. Online, most of that judgement lands on a handful of questions.

Online, the transferable-assets question is the hard one

A café's value sits in a lease, a fit-out and a location, and those move through the sale contract. An online store's value sits in registrations, licences and accounts held in a particular name — each with its own transfer path and its own way of quietly failing.

The customer list has rules attached

The customer database can be among the most valuable assets in an ecommerce sale, and it is the one the Privacy Act has something to say about. Most small businesses sit outside that Act — it generally does not cover a business with an annual turnover of $3 million or less — but a business that trades in personal information is covered regardless of turnover, and the OAIC's position is that a business selling assets, including the personal information held in its customer database, is trading in personal information. A sale of the whole business is the different case: where the transaction is a change of ownership or a sale of shares and the personal information is kept within the business, that is not trading in personal information.

During due diligence, the OAIC's guidance is that a vendor should avoid giving a prospective purchaser the names and other identifiers of its customers. That is workable: repeat-purchase rates, cohort behaviour, average order value, channel mix and list engagement answer the buyer's real question without handing over the list.

For an indicative figure from your own numbers, bizflip's market appraisal is free and publishes its method. It is an appraisal, not a formal business valuation — the formal engagement is performed under APES 225 by a qualified practitioner, and that is the one a bank or a court will accept.

Verify the numbers the way a buyer will

The advantage of selling online is that almost everything is machine-checkable. Store admin reports, payment-processor payouts, ad account spend and analytics can be reconciled against the BAS and tax returns for complete Australian financial years — 1 July to 30 June — and a serious buyer will do exactly that. A common gap sits between platform gross sales and reported GST turnover; it usually has an innocent explanation — refunds, marketplace fees netted off, multiple processors — that is far easier to give before an offer than after one. GST registration is required once GST turnover — gross business income minus the GST included in sales, with some further exclusions — reaches $75,000 or more, and there are 21 days to register once it does, so a store trading above that threshold without it is a due-diligence problem as well as a tax one.

Structure changes the number

Whether the deal is an asset sale or a share sale changes both the tax outcome and what the buyer receives. A sale can be GST-free as a supply of a going concern only where the conditions in the GST law, explained in the ATO's public ruling on the sale of a going concern (GSTR 2002/5), are met: the sale is for payment (what the law calls consideration), the buyer is registered or required to be registered for GST, both parties have agreed in writing that the supply is of a going concern, and the seller supplies all of the things necessary for the continued operation of the enterprise and carries the enterprise on until the day of the supply. For an online business, "all of the things necessary" is a live question — the domain licence, platform accounts, supplier arrangements and customer data all have to be on that list.

If there are staff — a warehouse, a customer-service team — the Fair Work Act's transfer-of-business rules can apply, but only where the buyer takes them on. A transfer of business happens when an employee starts with the new employer within three months of ending their job with the old one, doing the same or nearly the same work, and there is a connection between the two employers — selling the business's assets to the buyer is such a connection. Where that happens, the new employer has to recognise the employee's service with the old employer for most entitlements, including sick and carer's leave, requests for flexible working arrangements, and parental leave. Five are treated differently: redundancy, annual leave, long service leave, unfair dismissal and notice of termination. A buyer that is not an associated entity of the seller — the ordinary case in a trade sale — can choose not to recognise service for redundancy or annual leave, and the seller then pays redundancy on termination and pays out the untaken accumulated leave. Those are seller-side cash costs, so price them before going to market rather than discovering them at settlement. The old employer also has to give the new employer the employment records of any transferring employee.

Getting to an actual number

None of this produces a price. It tells you which numbers to fix, which risks a buyer will price, and which assets must be provably transferable before anyone pays for them. For a figure you would rely on in a negotiation, a bank application or a legal process, have an accountant, a business adviser or a business broker normalise your earnings and apply a multiple to your circumstances. Sector multiple ranges are set out in the valuation guides, and what comparable online businesses are listed for is a useful sanity check — though asking prices are not sale prices.
