How long does a business valuation take? Realistic timelines for every purpose.

The short answer

Most business valuations in Australia take between two and seven weeks from complete documents to signed report, depending on the depth of the engagement. At Prismi, an Essential report runs 10–14 business days, a Comprehensive report 15–25 business days, and a Defensible Valuation File 25–35 business days. Single-expert reports prepared for court run longer still, because the timetable is set by the litigation, not the valuer. Within those ranges, the single biggest variable is not the analysis. It is how quickly the complete document set arrives. Engagements that begin with clean, complete information routinely finish at the front of the range; engagements waiting on third-party documents finish at the back.

Timelines by engagement type

Elapsed time is driven by the depth of the engagement, not the size of the business. A larger business does not automatically take longer to value; a deeper engagement does — more methodologies tested, more evidence documented, more review before signature. Here are realistic timeframes for the engagement types Australian business owners and their advisers actually commission:

• ·Indicative range (calculation-level work, unsigned) — the fastest option, with timing quoted at engagement. Useful for early decisions; not a signed report and not suited to tax purposes
• ·Essential signed report (single methodology, senior-reviewer signed) — 10–14 business days. Straightforward CGT events with clean financials
• ·Comprehensive report (full APES 225 valuation engagement: multiple methodologies, normalised earnings, sensitivity analysis) — 15–25 business days
• ·Defensible Valuation File (three methodologies, complete evidence pack, prepared for likely review) — 25–35 business days
• ·Single-expert court report (family law and commercial disputes) — longer than any standard tier, set largely by the court timetable, the joint letter of instruction and both parties' disclosure
• ·Retrospective valuations — add time to any tier, because contemporaneous evidence from the historical date takes longer to source than current records

The clock starts when the documents are complete

The timeframes above run from receipt of a complete document set — not from the day the engagement letter is signed. That distinction matters more than any other single fact about valuation timelines. The discovery call, engagement letter and fixed fee are usually settled within a day or two. Then the document request goes out: financial statements for the last three to five years, current year-to-date management accounts, tax returns, shareholder and trust records, related-party loan schedules, key contracts and leases, and supporting evidence for any claimed add-backs. When that material arrives complete, the analytical clock starts and runs predictably. When it arrives in fragments, the elapsed time stretches — not because anyone is working slowly, but because normalisation cannot begin on half a financial picture, and methodology selection cannot be finalised until the entity structure and the asset being valued are confirmed.

What actually causes delays

The analysis phase of a valuation is the predictable part. The delays come from information — specifically, documents that sit outside the client's own filing cabinet. The most common sources, in roughly the order we encounter them:

• ·Prior-year financial statements still in draft with the accountant — nothing can be normalised from a draft that may change
• ·Third-party documents: the lease from the landlord's agent, the franchise agreement from the franchisor, loan statements from the bank
• ·Related-party loan schedules that do not reconcile between entities, which must be resolved before the balance sheet can be relied on
• ·Add-back claims without supporting evidence — an owner-remuneration adjustment asserted but not documented has to be substantiated or excluded
• ·Ownership records that do not match ASIC — share transfers executed but never registered, trust deeds amended but not located
• ·For retrospective dates: contemporaneous evidence — financial statements, industry data and comparable transactions from the historical period — which can take weeks to assemble

A week-by-week walkthrough

Here is how a typical Comprehensive engagement (15–25 business days) actually runs when documents arrive promptly. Essential engagements compress the same sequence; Defensible engagements extend the analysis and review stages rather than adding new ones:

• ·Week 1 — discovery call, engagement letter, fee fixed at engagement. Document request issued; completeness review on receipt, with gaps flagged immediately rather than discovered mid-analysis
• ·Week 2 — financial extraction and normalisation: add-back testing, related-party adjustments, maintainable earnings. Methodology selection confirmed against the entity, the evidence available and the purpose
• ·Week 3 — valuation calculations across the selected methodologies, sensitivity analysis, identification of the supportable range and the most supportable position within it. Draft report written
• ·Week 4 — senior reviewer sign-off. A senior reviewer who did not build the model works the file cold: methodology challenge, evidence check, recalculation of key figures. If the reviewer is not satisfied the conclusion is the most supportable position, the file goes back
• ·Week 4–5 — delivery of the signed report and evidence pack, optional adviser collaboration call with your accountant or lawyer, working file archived and retained

The review week is not padding

The senior-reviewer step is the part of the timeline clients most often ask us to compress, and the part we will not. Every Prismi report is signed under an independence statement by a senior reviewer who challenges the file before it leaves: is the methodology appropriate for the entity and purpose, is each input evidenced, do the calculations reproduce, and is the concluded position genuinely the one the methodology and evidence best defend. When the review sends work back — a multiple that needs stronger comparable support, an add-back that needs documentation, a discount whose magnitude needs tighter reasoning — that is the step doing its job, not the process failing. A report that skips independent review can certainly be delivered faster. It is also the kind of report that reads as thin when the ATO or a court asks who checked the work, and the answer is nobody.

When expedited turnaround is genuinely possible

Rush turnaround is available at 30% above the base fee, subject to capacity — and we quote it honestly, which means sometimes declining it. Expedited delivery is genuinely possible when the conditions that normally stretch a timeline are absent: a current valuation date rather than a retrospective one, a single entity, accountant-prepared financial statements already finalised, the complete document set delivered at engagement, and a client and adviser who commit to same-day responses to information requests. Under those conditions an Essential report can be compressed meaningfully and a Comprehensive engagement can land at the front of its range. What rush does not do is compress the scope. The methodologies still get tested, the evidence still gets documented, and the senior reviewer still signs — rush buys priority in the queue, not a lighter file. Where a matter is retrospective, multi-entity or contested, we will say the timetable cannot responsibly be shortened, and explain why.

Working to a hard deadline

If there is a hard date — a contract exchange, a lodgment deadline your accountant is managing, a court timetable — tell us at the discovery call, not in week three. We will say plainly whether the tier your matter needs fits the time available. Sometimes the answer is yes, with rush capacity. Sometimes an indicative range can inform the immediate decision while the signed report follows on the standard timetable. And sometimes the deadline and the depth the matter requires are incompatible — in which case we say so and decline the engagement on those terms, rather than sign a file the timetable did not allow us to review properly. One boundary worth stating: the deadline itself — when the CGT event occurs, when the return is due, whether an extension is available — is tax and legal territory. Prismi prepares the independent valuation; your accountant and lawyer manage the dates it has to serve.
