Buyers and sellers in London often wrestle over price, but experienced dealmakers know the real battleground sits a layer below: working capital. Get the working capital adjustment wrong and a fair headline price can turn into a costly mistake, either through immediate cash leakage post‑completion or through months of tense post‑closing disputes. Get it right and both parties exit the deal with confidence that the business can run normally on day one without a surprise cash call.
I have seen profitable companies sold for fair multiples that left buyers scrambling for emergency funds two weeks after completion because receivables were slower than expected and inventory was short. I have also watched sellers effectively subsidise a buyer’s future growth because they failed to cap the working capital they were leaving behind. The mechanics are not complicated, but the judgment required is subtle. London adds a few twists, particularly around seasonality, sector mix, and the pace at which mid‑market lenders and lawyers expect to see adjustments documented.
This guide unpacks the moving pieces, offers practical examples from deals in and around London, and gives buyers and sellers enough structure to negotiate with confidence, whether you are chasing an off market business for sale opportunity or preparing a tightly run process for a small business for sale London owners would recognise.
What “working capital” really means in a sale
In everyday management, working capital is current assets minus current liabilities. Dealmakers translate that into a narrower operational measure, usually receivables plus inventory plus prepayments minus payables, accruals, deferred income, and sometimes customer deposits. They strip out cash and debt‑like items, because those are handled separately through the cash‑free, debt‑free convention and a net debt adjustment at closing.
The purpose is simple. The price assumes the business can operate normally the day after completion without the buyer wiring extra money just to pay suppliers or fulfil orders. If the seller empties the till of working capital before handing over the keys, the buyer would immediately need to inject cash to fund the cycle. To avoid that scenario, deals include a target working https://liquidsunset.ca/exit-strategy/ capital, often called a peg, and a true‑up based on a completion balance sheet.
Two things matter more than any definition in the heads of terms. First, you must agree which line items are in or out of working capital. Second, you must agree the accounting policies that will apply in both the historic reference period and the completion accounts. Disputes usually flow from ambiguity here, not from the principle of a peg.
The London lens: sectors and seasonality
Greater London hosts a dense mix of services, wholesale and distribution, tech, creative, and specialty retail. Each behaves differently in the working capital cycle, and local quirks can be material.
A design agency in Shoreditch with project‑based fees might show slim receivables, sizeable WIP, and deferred income for retainers. A food distributor in Park Royal can carry seven to ten weeks of inventory and stretch payables just as long, with refrigerated stock and strict supplier terms. A specialist builder fitting out offices in the City will have chunky contract assets, milestone billing, and retention balances that age beyond 90 days. Each profile drives a different working capital story and a different negotiation.
Seasonality complicates everything. London retail spikes in November and December. B2B services often see January slowdowns with budgets resetting. Education‑focused suppliers spike in late summer. Setting a single target based on a flat twelve‑month average works for some businesses but produces unfair outcomes for others. If completion lands near a seasonal trough or peak, the peg should reflect that, or the contract should specify a seasonal methodology.
Anatomy of a working capital peg
Most deals agree a target based on an average of historical levels. The simplest method takes the twelve‑month average month‑end working capital. A more refined method weights the months to reflect seasonality or uses a trailing three‑month average to reflect current trading conditions. For companies with clear quarter‑ends and revenue cut‑off effects, month‑end snapshots can be misleading; daily or weekly averages over a sample period can help, though they require strong data.

What counts toward the peg deserves line‑by‑line thought. Inventory should be valued in accordance with historic policy, with obsolete or slow‑moving stock written down to a realistic net realisable value. Trade receivables should be net of specific provisions plus a reasonable general provision if that is the company’s policy. Prepayments matter, but only if they represent genuine future economic benefit. On the liabilities side, make sure accruals reflect earned but unbilled expenses and that deferred income matches cash collected for services yet to be delivered.
The art is to calculate the peg the way completion will be measured. If the company historically valued inventory at cost without freight, and you apply a completion policy including freight in cost, the peg and the actual will never match and a dispute is guaranteed. Pick one basis and document it clearly.
Completion accounts and the true‑up
The mechanics play out in three steps. First, agree a target and include it in the sale agreement. Second, at completion, set a provisional price based on the headline enterprise value plus or minus net debt and working capital relative to the target. Third, within a defined period, the buyer prepares completion accounts, the seller reviews, and the difference to the target becomes a post‑completion payment from buyer to seller or vice versa.
London practice typically allows 30 to 60 days for draft completion accounts, then 20 to 30 days for review, with an independent accountant appointed if the parties cannot resolve differences. Caps sometimes apply to the adjustment to avoid outsized swings. Be careful though: hard caps can create perverse incentives to under‑ or over‑state items within the cap.
I favour concise, unambiguous wording on the order of priority. Accounting policies set out in a schedule should come first. Where silent, apply the historic policies and practices. Only then fall back to the relevant accounting framework, usually UK GAAP or IFRS. Ambiguity over policy order is the seed of many avoidable disputes.
Common traps that cost real money
I keep a short mental list of traps that repeatedly hurt otherwise sophisticated parties in businesses for sale in London.
- Mismatched aged debtors and revenue recognition. In project‑based companies, unbilled WIP can be material. If revenue is recognised on milestones but invoices lag, debtors will look clean while WIP hides the real exposure. Buyers should reconcile WIP to future billing with a cold eye. Sellers should ensure WIP accounting mirrors their revenue policy and is consistently applied in both the peg and completion accounts. Obsolete inventory. Small distributors often carry stock that has not moved in a year. Without clear obsolescence policies, the peg will be inflated by dead items that will be written down post‑completion, shifting value from seller to buyer. An agreed ageing provision curve with evidence from historic clearance rates saves arguments. Prepayments and deferred income in subscription models. Agencies and SaaS‑like businesses increasingly take upfront payments. If cash has been collected for a service that will be delivered after completion, that liability should sit in working capital as deferred income. Sellers sometimes understate it; buyers sometimes double count it alongside cash. Clear mapping avoids double counting and errant claims. Accruals for bonuses and taxes. In London, staff bonuses are common and typically accrue through the year. If bonuses earned pre‑completion are not accrued properly, they will hit the P&L post‑completion and the buyer will pay them. The working capital peg should mirror the level of accrual that will exist on completion, not a smoothed annual figure that ignores timing. Supplier terms changing during the process. A vendor negotiating a sale might stretch payables just before completion to boost cash. If the peg ignores this shift, the buyer inherits a cash squeeze. Track payable days and supplier terms month by month through the process and normalise the peg to the true steady state.
That list could be longer, but discipline around policies, ageing, and consistent treatment prevents most blow‑ups.
Setting the target: judgement over formula
Start with data, not a rule of thumb. Pull at least 24 months of month‑end working capital, break it into components, and overlay operating metrics: revenue, gross margin, days sales outstanding, inventory turns, days payables. Plot seasonality. Identify structural changes like a major new contract, a warehouse move, or a change in supplier terms.
From there, choose a methodology that reflects how the business will actually look on the completion date. If closing is planned for late September for a school‑supply wholesaler, the peg should be higher than the annual average, because inventory and receivables spike in August and early September. If closing will run into January, many consumer businesses will dip below their average.

For distressed or high‑growth companies, historic averages can mislead. A rapidly scaling e‑commerce brand can see working capital balloon in step with growth. A flat average will starve the business on day one. In those cases, consider a forward‑looking peg based on a detailed, seller‑provided working capital forecast that uses the same policies as the historic accounts, with protective adjustments if the forecast proves optimistic.
UK specifics: accounting frameworks and tax
In the UK mid‑market, many private companies report under FRS 102, not IFRS. That affects revenue recognition, lease accounting, and the treatment of financial instruments. Align the completion accounts to the company’s framework and policies, not the buyer’s group reporting framework. If the buyer intends to convert to IFRS post‑completion, that is their choice, but the true‑up should not be measured against a different basis than the peg.
VAT and payroll taxes can muddy the working capital pool. Generally, unpaid VAT and PAYE are treated as debt‑like items rather than operating working capital. Spell this out. HMRC timing quirks around quarterly VAT returns sometimes create spikes near quarter‑end. Exclude VAT from receivables and payables where possible and track the VAT creditor separately in the net debt calculation.
For London businesses with international transactions, currency adds noise. If the company holds receivables in euros or dollars, define whether the completion accounts translate at the completion date rate or a historic average. This is a small technical choice with real value implications.
Case snapshots from the London market
A West London wholesale bakery changed ownership at a sensible multiple. The peg used a twelve‑month average. Completion was in early November, while the business built up festive inventory and receivables. Two weeks later, the buyer faced a cash shock. The peg had been set too low for a November close. A seasonal adjustment mechanism would have avoided the issue: either a specific November peg or a methodology that scaled the target to revenue for the prior eight weeks.
A creative studio near Holborn had deferred income for retainers equal to six weeks of revenue. The first draft of the sale agreement treated deferred income as outside working capital, effectively gifting the liability to the buyer without a price benefit to the seller. That would have been an avoidable windfall to the buyer. The parties corrected it by including deferred income in working capital and aligning the peg to the historic average level.
An electrical contractor working on fit‑outs around Canary Wharf had material retentions receivable that only released six months after completion of works. The peg originally included retentions at face value. We adjusted to include only retentions less than 180 days old and applied a haircut based on historic recovery rates. That kept the peg fair and avoided a disproportionate post‑completion true‑up when old retentions were written down.
The role of brokers and advisors in London and London, Ontario
Not every owner has an internal finance team that lives and breathes working capital. A good broker earns their fee by getting these details right early, packaging a business for a clean sale, and keeping parties away from fights that burn time and goodwill.
In the UK capital, boutique intermediaries handling a business for sale in London will typically insist on a working capital schedule in the data room, plus historic monthly data and clearly documented policies. This helps buyers who want to buy a business in London evaluate not just headline price but cash demands in the first quarter of ownership. Some buyers dig for off market business for sale leads to avoid competition. If you go that route, expect wider variance in the quality of working capital data, and budget extra diligence time.
Across the Atlantic, owners seeking to sell a business London Ontario entrepreneurs would know face similar mechanics with local quirks. For businesses for sale London Ontario listings, banks and business brokers London Ontario expect to see monthly working capital data and clear treatment of seasonality, particularly for construction and distribution firms. If you plan to buy a business London Ontario buyers are chasing, or to buy a business in London Ontario where inventory and supplier terms can be tight, insist on a peg methodology that accounts for Canadian tax timing and any holdbacks customary in that market. A seasoned business broker London Ontario based will also guide smaller owner‑operators on inventory counts and obsolescence that otherwise derail a closing meeting. Whether you are on the buy side or sell side, tap advisors who actually run reconciliations, not just write term sheets. That includes firms like sunset business brokers or liquid sunset business brokers if they are active in your niche, provided they are willing to dig into month‑on‑month working capital movements, not just blast listings for companies for sale London wide.
Negotiating the schedule: documentation that prevents disputes
The working capital schedule attached to the sale agreement deserves craft. It should list included accounts with clear definitions, the target amount, the accounting policies, and the mechanics for completion accounts. Where estimates apply, like inventory provisions or WIP valuation, require supporting schedules and methods, not just single numbers. If the company relies on cycle counts or periodic stocktakes, define the cut‑off and who witnesses the completion count. I encourage sellers to pre‑empt buyer anxiety by running a dry‑run count a month before completion and sharing the reconciliation.
Be specific about aged balances. For receivables over 90 days, agree whether they are included at face value, partially, or excluded. If included, can the buyer claw back if they are not collected within a set post‑completion period? That kind of provision makes sense for small deals with concentrated customer bases. For larger companies with diversified debtors, aged receivables should usually be covered by a documented provision policy, not bespoke clawbacks that create complexity.
If the business has customer deposits, align the treatment across the peg, completion accounts, and any net debt definitions. Deposits often get miscategorised, leading to accidental double counting between working capital and net debt.
How the adjustment intersects with price and earn‑outs
Buyers sometimes accept a higher headline price in exchange for a tighter working capital peg with a generous true‑up mechanism. Sellers sometimes prefer to give ground on the peg to firm up price and reduce post‑closing uncertainty. Earn‑outs complicate this balance. If an earn‑out depends on post‑completion EBITDA, and the buyer inherits a weak working capital position, the buyer may curtail marketing or hiring in the first months to conserve cash, reducing the earn‑out. That is not theoretical. I have seen it happen in London service businesses where deferred income and WIP were under‑analysed.
If you must have an earn‑out, ensure the working capital peg gives the business enough oxygen to run to plan. Spell out operating covenants that the buyer will not starve the business in ways that undermine the earn‑out, while still allowing sensible management discretion.
Preparing as a seller: practical steps
Sellers who prepare six to nine months in advance control the narrative. Start by cleaning AR and AP ledgers. Tidy credit notes, chase overdue receivables, write off the truly dead, and document provisions that are supportable with history. Review inventory. Run an ageing report, set an obsolescence policy, and clear dead stock at realistic discounts rather than dragging it into a diligence room. Document revenue recognition and WIP valuation with examples. Align your monthly management accounts to your statutory policies; if they differ, reconcile them.
If your business is a small business for sale London owners have run informally, do not wait for a buyer to discover inconsistencies. Commission a lightweight quality of earnings review including a working capital analysis. It is not just for bigger companies. It pays for itself in negotiation leverage and smoother completion.
Preparing as a buyer: diligence beyond the spreadsheet
Buyers sometimes get lost in headline valuation and neglect the blocking and tackling of working capital. Besides the numbers, speak with the finance manager and, if possible, the credit controller and purchasing lead. Ask about customers who habitually pay late and suppliers who change terms without notice. Walk the warehouse. Touch boxes. If SKUs are dusty, you will find obsolescence provisions are light. In service businesses, review a sample of contracts for billing milestones and acceptance criteria. If revenue is recognised ahead of client acceptance, deferred income may be understated.
Bring your lender into the conversation early. If the acquisition debt includes a working capital facility, align your borrowing base with the company’s realities. Some London lenders advance only against receivables under 90 days. If 20 percent of the debtor book sits at 120 days with good payers in construction, your borrowing base might be tighter than expected. That matters on day one.
Dispute resolution and independent accountants
Even diligent parties can disagree. Appointing an independent accountant as expert, not as arbitrator, is standard market practice. The sale agreement should limit the expert’s remit to accounting judgments and specify that their decision is final except for manifest error. Provide evidence packages with clear audit trails. Experts dislike surprises and narrative arguments; they prefer ties to be broken by documented policy and consistent historic practice.
I recommend keeping disputed items narrow. If you argue about the valuation of WIP or the level of an accrual, focus on that item and its policy, not on reopening the overall peg. Courts do not want to see deal‑level economics re‑litigated when the parties agreed a method.
When the peg should be zero
Occasionally, the right target is effectively nil. Pure marketplaces, agencies that collect fees monthly in arrears with minimal WIP, and asset‑light software companies with annual contracts billed monthly and no material deferred revenue might operate with minimal net working capital. But dig into the details before accepting zero. Many agencies take retainers and recognise revenue evenly. That creates deferred income. Many SaaS businesses bill annually in advance. That creates a liability and a cash windfall, which belongs on the buyer’s balance sheet post‑completion only if the seller’s price and peg accounted for it.

A blanket zero peg across sectors is a lazy shortcut. Use it only where the data and policy support it.
Cross‑border buyers and currency timing
If you are a North American buyer targeting a business for sale London, Ontario or London in the UK, be alert to currency effects and different banking norms. UK suppliers often accept longer payables from well‑known retailers but demand stricter terms from smaller firms. In Canada, payables in construction often align with pay‑when‑paid clauses. Both environments shape working capital. Align the peg to the local rhythm, not the buyer’s home practice.
Closing day logistics that make or break the count
The best‑drafted schedule fails if completion day logistics are sloppy. If inventory is material, perform a count as near to completion as possible, ideally the night before, with both parties or their representatives present. Freeze movements or track them carefully from count to completion. For receivables, capture a clean AR ageing at close of business on the last day before completion, then roll forward collections and billings to the completion moment with a clear reconciliation. For payables, lock the AP ageing and capture manual accruals with supporting documents. The smoother the cut‑off, the fewer arguments afterwards.
Why this matters to your broader deal strategy
Price grabs headlines, but cash dynamics determine whether the first quarter as an owner feels like a victory lap or a firefight. If you are scanning companies for sale London brokers promote, ask for the working capital track record early. If you chase an off market business for sale, assume you will need to build that record yourself from raw ledgers and bank statements. If you are positioning a small business for sale London Ontario or planning to sell a business London Ontario operators will compete for, invest in cleaning working capital before you test the market. Good buyers and lenders notice.
In the end, working capital adjustments are a trust exercise wrapped in accounting. They force both parties to answer a practical question: what does it really take, in cash terms, to run this business normally on day one? When that answer is developed with evidence, written with precision, and tested against the calendar, deals close cleanly, employees keep working without drama, and the price paid reflects the reality handed over. That is the result everyone wants, from seasoned private equity teams to first‑time entrepreneurs looking to buy a business in London or to buy a business in London Ontario with confidence that their first week as owner will not start with a surprise call to the bank.
