Selling your business: how to get valuation and due-diligence ready

Why preparation sets the price

A sale process runs on trust and evidence. A buyer forms a view of value from the information you provide, then spends weeks — sometimes months — testing that view in due diligence. Everything the buyer cannot verify gets discounted; everything that surprises them gets renegotiated. In practice, three things follow:

• Clean records are worth real money. A business whose numbers reconcile, whose contracts are signed and whose filings are current is simply worth more than an identical business with messy records, because the buyer prices in less risk.
• Surprises found late cost more than issues disclosed early. An issue you identify and explain up front is a footnote; the same issue discovered by the buyer's advisers mid-diligence is a price chip — and a reason to doubt everything else.
• Momentum matters. Deals die in delay. Every week spent reconstructing records or chasing missing documents gives the buyer time to cool, markets time to move, and staff time to hear rumours.

How buyers value a private SME

There is no single formula, but for most trading businesses in Singapore, buyers converge on a small set of methods:

• Earnings multiples — the workhorse for profitable SMEs. The buyer applies a multiple to normalised EBITDA (or sometimes net profit). The multiple reflects industry norms, growth, margin quality, customer concentration and transferability — how much of the business walks out the door with the owner.
• Adjusted net assets — used for asset-heavy or property-holding businesses, and as a floor value elsewhere: the balance sheet restated to market values.
• Discounted cash flow (DCF) — a cross-check more than a primary method for smaller deals, since it depends heavily on forecast assumptions.

Two implications for a seller. First, because value is a multiple of earnings, every dollar of provable recurring profit is worth several dollars of price — which is why cleaning up the earnings picture is the highest-return preparation work you can do. Second, the multiple itself is negotiable, and it moves on the qualitative factors: recurring revenue, a capable second-tier management team, documented processes and a diversified customer base all push it up.

Normalised earnings: the number that matters

Reported profit and the profit a buyer will actually enjoy are rarely the same number. Normalisation adjusts reported earnings for items that will not continue under new ownership, typically:

• Owner remuneration — adjusted to a market salary for the role. Many founders underpay themselves (overstating profit) or pay themselves through the company well above market (understating it).
• Personal or discretionary expenses run through the business — vehicles, travel, family members on payroll for nominal roles.
• One-off items — grant income, disposal gains, COVID-era support, a bad-debt write-off, a one-time legal dispute.
• Non-arm's-length arrangements — below-market rent on a director-owned property, intercompany charges with related entities.

Prepare this analysis before the buyer does. A seller who presents a clear bridge from audited (or at least properly compiled) financial statements to normalised EBITDA — with evidence for every adjustment — controls the valuation conversation. A seller who leaves the buyer's advisers to build it will find the adjustments only ever go one way.

The five areas of due diligence

Due diligence is the buyer's systematic verification of what they are buying. For a Singapore SME it typically covers five areas — and the preparation task is to imagine each request list and have the answers ready.

1. Financial

• Two to three years of financial statements, prepared consistently — audited statements carry the most weight; where the company relies on the small-company audit exemption, a voluntary audit ahead of a sale is often money well spent.
• Monthly management accounts that reconcile to the year-end statements, with revenue recognition applied consistently.
• Aged receivables and payables, inventory records, and a clear picture of normalised working capital — buyers price deals on a “normal” level of working capital, and disputes over it are one of the most common sources of post-deal friction.
• A full list of borrowings, hire purchase, guarantees and off-balance-sheet commitments.

2. Tax

• All corporate income tax filings (ECI, Form C-S / Form C) current, with assessments finalised and no open IRAS queries.
• GST returns filed and reconciled to the accounts; input tax claims defensible.
• Payroll taxes in order — CPF contributions correct and on time, IR8A filings complete, and any foreign-employee obligations met.
• Withholding tax on payments to non-residents identified and accounted for — a classic small-company blind spot.
• Related-party transactions documented at arm's length.

3. Legal and corporate

• ACRA records accurate and filings current — registers, Annual Returns, and a share register and cap table that match reality, with every past share transfer properly stamped and documented.
• Signed, current contracts with key customers and suppliers — and a check for change-of-control clauses that let counterparties exit when the company is sold.
• Licences and permits valid and, where relevant, transferable.
• Intellectual property — trademarks, domains, software — owned by the company, not the founder personally.
• Any past or pending disputes, and how they were resolved.

4. Operational and HR

• Employment contracts and Key Employment Terms for all staff; clarity on which employees are critical and how they will be retained through a sale.
• Documented processes for the activities that generate revenue — the test is whether the business can be operated from its manuals and systems, not from the owner's head.
• IT systems, data protection (PDPA) compliance, and insurance cover appropriate to the business.

5. Commercial

• Customer concentration — a business where one customer is 40% of revenue will be priced accordingly; reducing concentration is slow work, which is why it belongs at the start of the timeline.
• Revenue quality — contracted and recurring revenue is worth more than repeat-but-uncommitted revenue, which is worth more than one-off project income.
• Supplier dependencies, market position and a credible, numbers-based growth story for the buyer to underwrite.

Share sale vs asset sale — and the tax that follows

How the deal is structured changes what you keep. The two basic forms:

• Share sale — the buyer purchases the company itself, taking on its history, contracts and liabilities. Singapore does not tax capital gains, so for an individual seller the gain on shares held as a long-term investment is generally not taxable — though gains can be taxed as income where the facts suggest trading (frequent transactions, short holding periods, sale as the intent from the outset). The buyer pays stamp duty of 0.2% on the higher of the consideration or the net asset value of the shares.
• Asset sale — the company sells its business and assets, and the sellers extract the proceeds afterwards. Gains on trading assets and balancing charges on plant and equipment can be taxable in the company, GST applies to the assets transferred unless the deal qualifies as an excluded transfer of a going concern, and getting the cash out (dividends, then closing the company — see our guide to strike-off vs members' voluntary liquidation) adds further steps.

Buyers often prefer asset deals (cherry-pick assets, leave liabilities behind); sellers usually prefer share deals (cleaner exit, better tax outcome). The gap between the two is a negotiating variable in itself — and the time to understand your after-tax position under each structure is before offers arrive, not after. Structure, warranties and indemnities warrant specific professional advice on the facts of your deal.

The 12–24 month preparation timeline

Working backwards from a target sale date:

• 18–24 months out — fix the structural issues: reduce owner dependence by building a second tier of management, address customer concentration, move personal expenses out of the business, formalise related-party arrangements, and consider a voluntary audit so the sale is supported by two audited year-ends.
• 12 months out — tidy the records: contracts signed and filed, ACRA and share register reconciled, IP transferred into the company, licences confirmed, tax filings and CPF brought fully current.
• 6 months out — build the sale pack: normalised-earnings analysis with evidence, three-year financial summary, working-capital analysis, and a data room assembled around the five due-diligence areas above.
• 3 months out — take advice on deal structure and your after-tax proceeds, agree valuation expectations against market comparables, and decide how buyers will be approached — directly, through your network, or via a broker or corporate finance adviser.

Common deal-killers

• Numbers that move. Management accounts that do not reconcile to the financial statements, or a normalised-EBITDA figure that shrinks every time it is tested, destroy buyer confidence faster than any single issue.
• The business is the owner. If customers, suppliers and staff all deal with the founder personally, the buyer is buying a job, not a business — expect a lower multiple, a long earn-out, or both.
• Undocumented arrangements. Handshake deals with key customers, unwritten staff arrangements, informal loans from directors — each one becomes a warranty negotiation.
• Open tax exposure. Unfiled returns, late CPF, aggressive GST claims or unaddressed withholding tax surface reliably in diligence and come off the price with interest.
• Change-of-control surprises. Discovering mid-deal that your biggest customer contract terminates on a sale is a problem no data room can fix retrospectively.
• Seller fatigue. Diligence is demanding, and running it while also running the business unprepared leads to slipping performance mid-deal — the one thing guaranteed to reopen the price.

The bottom line

A business sale is won in preparation. Buyers pay full prices for businesses whose earnings are provable, whose records are clean, and which will keep performing when the founder leaves. Start 12–24 months out: normalise the earnings picture, put the financial, tax and corporate records in order, reduce the business's dependence on you, and understand your after-tax position under a share deal and an asset deal before the first offer arrives. The work is unglamorous — and it is routinely the difference of a meaningful percentage of the final price.
