How much does an e-commerce business valuation cost in Australia?

The short answer

At Prismi's published fixed fees, a single-brand online store on one primary platform, with clean accounting and a straightforward ownership structure, typically sits at the Essential tier from $1,495 + GST. Where paid and organic traffic are both material revenue sources, or a second methodology is needed as a cross-check, the matter moves to the Comprehensive tier from $3,995 + GST. Multi-marketplace operations, private-label supply chains and aggregator-comparable questions typically warrant the Defensible Valuation File from $8,995 + GST or above. Across the wider market, full valuation reports in Australia typically run $5,000–$15,000+ at traditional firms, and most firms quote privately rather than publish a price. E-commerce matters often sit toward the upper half of that band, because the evidence-gathering is more involved than the absence of a shopfront might suggest — platform dependency, traffic-source concentration and inventory verification replace the lease review and plant schedule a bricks-and-mortar valuation would otherwise need.

Prismi's fixed fees for e-commerce valuations

Fees are fixed at engagement and never contingent on the outcome the report reaches. Situational extras are defined rather than hourly: a retrospective valuation date adds $495 per historical date, additional entities add $750 each (relevant where brands trade through separate structures), and rush turnaround adds 30%. A single-entity store valued at a current date carries no surcharges at all.

Why 'no premises' does not mean 'less work'

A bricks-and-mortar business has a lease to review, plant and equipment to schedule, and a location to assess. An e-commerce business has none of that — but the absence of those items does not shrink the scope, it relocates it. In place of a lease review, the valuer needs to understand platform dependency and the terms under which the business trades on it. In place of a plant and equipment schedule, the valuer needs to verify inventory — landed cost, condition, and what is sitting in transit or in an obsolescence risk zone. In place of assessing a physical location, the valuer needs to assess where the traffic and the customer relationship actually sit, and whether either is transferable. The evidence-gathering is different in kind, not smaller in size. That is the main reason a straightforward-looking online store can still land in the Comprehensive or Defensible tier rather than the Essential one.

The platform-dependency driver

The single biggest scope driver in an e-commerce valuation is how concentrated the business is on one channel. A store selling through its own Shopify site with an owned email list and diversified organic traffic carries a materially different risk profile to a business that generates most of its revenue through a single Amazon seller account. Account-suspension risk is real and has to be assessed on the evidence: has the account had policy strikes, IP complaints, or performance notices; is the seller account in the individual's name or the entity's name; and — critically for a related-party transfer or a sale — is the channel relationship itself transferable, or does the buyer effectively need to build a new seller history from zero. Where marketplace concentration is high, the methodology has to weight this risk explicitly, usually through a higher discount rate or a more conservative maintainable-earnings figure rather than through a footnote. This analysis takes real time, and it is one reason multi-marketplace operations typically sit above the Essential tier.

Traffic mix and customer-acquisition cost as evidence

For a physical retailer, footfall and repeat trade are largely observable. For an e-commerce business, the equivalent evidence is the traffic mix: what proportion of revenue is paid (and therefore stops the moment ad spend stops) versus organic, direct, or email-driven (and therefore more likely to persist under different ownership). A business generating most of its revenue from paid search or paid social has a maintainable-earnings position that looks very different once acquisition costs are properly normalised against a realistic, sustained spend level — not the spend level in a single strong quarter. Ad-account history matters too: a long, stable account with consistent return-on-ad-spend is different evidence to a recently created account or one with a history of suspensions. Ownership of the email list, and its engagement metrics, is often the strongest piece of evidence for a defensible, channel-independent revenue base, because an owned list transfers with the business in a way that a rented audience on someone else's platform does not.

Inventory verification — the e-commerce stocktake

A traditional retail valuation includes a stocktake. The e-commerce equivalent is inventory verification, and it is more involved than it sounds. Landed cost has to be checked against actual supplier invoices, freight and duty — not just the unit cost quoted in a spreadsheet — because landed-cost errors compound directly into gross margin, which flows straight through to maintainable earnings. Obsolescence risk needs assessing for seasonal or trend-driven stock, private-label ranges with long reorder lead times, and anything sitting in aged inventory reports. Pre-paid stock in transit — increasingly common with overseas private-label manufacturing — needs to be identified and treated correctly, since it can otherwise inflate or understate the asset base depending on how it has been booked. None of this is optional analysis; it is the working evidence that supports (or does not support) the earnings and net asset figures the rest of the valuation depends on.

What pushes an e-commerce matter into a higher tier

Several factors move a matter from Essential toward Comprehensive or the Defensible Valuation File, and it is worth knowing them before the discovery call.

• ·Multi-marketplace operations — Amazon, eBay, Shopify and wholesale channels each need separate revenue-quality and dependency analysis
• ·Private-label products with overseas supply chains — landed cost, MOQ commitments and supplier concentration all need evidencing
• ·Aggregator-comparable questions — where a founder is benchmarking against FBA-aggregator acquisition multiples, the comparables need genuine scrutiny, not a like-for-like assumption
• ·High paid-traffic dependency — normalising acquisition cost against a sustainable spend level takes more analysis than a predominantly organic store
• ·Recent platform account issues — any suspension, strike or policy dispute history needs to be factored into the risk position
• ·Multiple entities or brands trading under one operating structure

What the Essential tier does not cover — and what to send us first

The Essential tier tests a single methodology and is built for straightforward matters — a single-platform store, clean records, and a purpose such as a routine CGT event or an internal ownership decision where the file is unlikely to be tested. It is not the right tier for a matter involving family law, a contested shareholder exit, or a transaction where ATO review is a real prospect, because those matters benefit from a second methodology as a cross-check and a fuller evidence pack behind it. It is also not the right tier if the business is genuinely multi-marketplace or carries meaningful platform-concentration risk, since that analysis is better supported at Comprehensive or above. Come prepared with platform account history and any policy notices, traffic and ad-account reporting for at least the past 12 months, inventory and landed-cost records, and email-list or CRM engagement data if you hold it — the clearer this evidence is going in, the more efficiently the engagement runs, and the more supportable the resulting position.

The honest trade-off, and where to go next

The Essential tier is priced from $1,495 + GST because its scope is fixed, not because corners are cut: one methodology, applied properly, senior-reviewer signed, with the working file retained for ten years. For a single-platform store with clean records and a straightforward purpose, that is a complete and proportionate report. But be honest about what a single methodology cannot do. It does not produce the cross-checked supportable range that contested matters need, and it is not suited to family law, partnership disputes or positions carrying realistic ATO-dispute risk — for those, stepping up to Comprehensive or the Defensible Valuation File at engagement is far cheaper than commissioning a second valuation after a thin one is challenged. If in doubt, the discovery call will confirm the right tier before the engagement starts — fees are fixed once the scope is agreed, not adjusted afterward.
