Walk down Richmond Row at closing and you see it: shops dimming, kitchen lights still blazing behind a quiet dining room, vans loading at the back. Cash registers sleep, but the business is still burning money. When you buy a business in London, the part that rarely makes the glossy brochure is the money you need the second the ink dries. Not for the purchase. For the next morning.
That bucket is working capital. It keeps payroll met, suppliers calm, stock on shelves, and your bank manager relaxed while revenue catches up. Buyers get seduced by price and multiples, then trip on the float between invoicing and collecting, or the lag between paying vendors and selling goods. Get it right and you not only stay afloat, you buy time to improve operations without panic.
This is a primer, but a practical one, grounded in how deals actually move in London, Ontario. I will reference what you hear from a business broker London Ontario owners trust, and what shows up in diligence when scanning a business for sale London, Ontario or nearby. Numbers will vary by sector, but the method doesn’t.
The first question on working capital: what are you actually buying?
Asset purchases and share purchases treat working capital differently. In a share purchase, you acquire the company intact, liabilities and all, typically with a “normalized working capital” target baked into the purchase price. If the actual working capital at closing falls short of that target, you get a reduction dollar for dollar; if it exceeds, you pay more. In an asset purchase, you may buy inventory and sometimes accounts receivable, but you generally leave payables behind. That sounds cleaner, but vendors respond to change. You lose history-based terms and often must cash-and-carry for a while, which spikes your working capital need for the first three months.
A business broker London Ontario buyers rely on will raise this early: what’s the working capital peg, and how is it defined? It is not enough to say “current assets minus current liabilities.” You need definitions for included AR aging buckets, obsolete inventory reserves, payroll accruals, GST/HST, gift card liabilities in retail, customer deposits in contracting, and warranty provisions in service businesses. I have seen a “simple” peg swing 200,000 dollars against a 1.6 million purchase, all because of prepaid expenses and customer deposits that the parties forgot to specify. It wasn’t trickery, just sloppy definitions.
London specifics that move the needle
London, Ontario isn’t Toronto, and that matters in small ways that add up.
- Seasonality is sharper in some sectors. University cycles and tourism affect retail corridors near Western and Fanshawe. Construction ramps hard from April to October and eases in winter. Restaurants see September boosts and summer patio spikes, then exam lulls. Working capital should be set for the roughest two-month stretch in your first year, not the average. Terms culture is polite but firm. Many local distributors still work on net 30 but expect on-time cheques. If you are a new owner, even a good business for sale London Ontario suppliers know for years may reset you to COD for one or two orders. Expect an extra 30 to 60 days of cash tied up while you rebuild trust. Wage timing is predictable, yet binding. Weekly or biweekly runs, plus source deductions due on the 15th or 25th depending on remitter status. First-time buyers underestimate the CRA schedule and get clipped by penalties. Build in the payroll float plus 15 percent. Utilities and rents rarely forgive the new owner bump. Some landlords request a deposit equal to one or two months’ rent on change of control, even if the business has never missed a payment. Same for hydro if accounts are reset during an asset purchase.
Each of these factors shifts your Day One buffer. When you scan a business for sale London, Ontario that looks tidy on paper, test the scenario in the worst month with conservative supplier terms.
How much working capital do you need? Start with the cycle
The working capital cycle is simple to name and easy to misjudge: you spend on inventory and payroll, you sell, you collect. If money goes out faster than it comes in, you need capital. You can estimate the requirement with a few anchored metrics.
Days Inventory Outstanding (DIO): how long inventory sits before sale. Days Sales Outstanding (DSO): how long you wait to collect from customers. Days Payables Outstanding (DPO): how long you get to pay suppliers.
Your cash conversion cycle is DIO + DSO - DPO. If that equals 40 days, you are financing roughly 40 days of operating expenses and cost of goods, less your cash sales. If monthly cost of sales and operating spending totals 120,000 dollars, 40 days is about 160,000 dollars of working capital. Add a buffer for surprises, typically 10 to 25 percent for small businesses. The buffer size depends on how volatile sales are and whether a single customer concentrates risk.
Here is a concrete example from a London-based HVAC contractor I advised. Annual revenue: 3.2 million. Mix: 60 percent commercial, 40 percent residential service and install. DIO hovered at 18 days due to stocked parts and units. DSO averaged 36 days for commercial, 7 for residential, weighted to 25 days overall. DPO was 20 days. That produced a 23-day cash conversion cycle. The business ran 250,000 dollars per month in combined payroll, materials, and overhead. Twenty-three days is roughly 190,000 dollars, and we added a 50,000 dollar buffer because a couple of municipal clients paid late each summer. The lender originally underwrote 100,000. That would have been a painful squeeze in July when two technicians were on overtime, and rebate jobs spiked material buys.
Why the historical balance sheet lies, and how to fix it
Sellers sometimes hand over a trailing twelve months working capital average and call it a day. Good start, not the finish. If they starved inventory before marketing the business to look lean, or paused payables, the average is sugarcoated. If they collected aggressively in the last quarter to dress AR, then promised customers an extra discount to delay delivery into your ownership month, the average is distorted the other way.
Fix it by looking transactionally:
- Match weekly receipts and disbursements for a full year, not just monthly statements. You will see pay cycles, tax remittances, and seasonal lumps that monthly averages hide. Re-age receivables on a rolling basis and circle any accounts over 60 days. If the seller calls them “good as gold,” insist on proof of recent payments. Otherwise, discount them from the peg or hold back part of the purchase price. Sample inventory for obsolescence and shrink. In auto parts and industrial supplies, 5 to 15 percent can be dead stock unless the seller has strong rotation. You do not want to finance inventory that will turn into clearance sales at 40 cents on the dollar. Reconcile customer deposits and unearned revenue in service businesses. If you inherit 100,000 dollars in deposits for jobs that require 150,000 dollars of costs post-closing, that is not working capital for you; it is a liability that consumes capital.
A serious business broker London Ontario buyers work with will pressure test these. If the broker is reluctant, take that cue.
Banks, BDC, and what they like to see
Financing working capital is rarely as simple as asking the bank for an extra line. Senior lenders prefer the line to self-liquidate, which means it rises and falls with receivables and inventory. They will look for a borrowing base formula tied to AR and inventory, with exclusions for receivables over 90 days and inventory reserves for slow movers. If you hope to use a term loan for working capital, be ready to explain why the cash cycle is structurally longer than the bank’s comfort zone and how you will shorten it.
BDC often fills the gap, especially if you are buying goodwill-heavy businesses without a lot of fixed assets. Their working capital loans are patient, but the underwriting still anchors on the cash conversion cycle and free cash flow coverage. In London, many buyers layer capital this way: a senior term loan for the acquisition, an operating line against AR and inventory, and a BDC subordinated tranche for the working capital buffer. On top, add vendor take-back financing that allows interest-only for the first year. That stack buys breathing room.
If you review a business for sale London, Ontario that shows thin margins, resist the urge to over-lever to compensate. Thin margins and long cycles create fragile math. You will want the lowest fixed charges possible while you tune pricing, scheduling, and supplier terms in the first six months.
Payroll, the non-negotiable clock
Payroll is the heartbeat that sets your real working capital needs. Missed payroll turns staff loyal to the old owner into skeptics. Even one late run can trigger departures. When you model working capital, project payroll with overtime and statutory add-ons. Factor vacation payouts for long-time employees if the seller expects you to reset balances. In an asset sale, sometimes the buyer agrees to honor prior service for vacation entitlement but not for severance obligations. That sounds tidy until you realize the accumulated vacation liability converts into cash in your first summer when multiple technicians book the same two weeks.
If the business pays weekly and you plan to switch to biweekly, socializing that change early matters. Do it in month two, not the first pay period, and sweeten with a one-time transition bonus if morale needs it. Even small shifts in timing can free five figures of float, but never at the cost of goodwill in your team.
The inventory trap in retail and distribution
A retail store on Richmond or a parts distributor near the 401 can devour working capital if you misread turns. If the seller shows a tidy gross margin and claims “we buy smart,” dig deeper. Ask for SKU-level sales and last-order dates. If 30 percent of SKUs have not sold in six months, either you discount and clear on day one or you finance dust. In one London specialty retailer, we found 140,000 dollars of inventory that had not moved in 270 days, roughly half the on-hand. We carved a purchase price adjustment tied to a six-month clearance schedule, with 70 cents on the dollar paid only as items sold. Without that mechanism, the buyer would have needed an extra 100,000 dollars of working capital to cover rent and payroll while dead stock slowly turned into cash.
Distribution businesses often rely on manufacturer dating programs, like 2 percent 10 net 60 or seasonal extended terms. Those programs can vanish at ownership change. Get supplier letters confirming continuity, not just the seller’s assurances. If terms reset from net 45 to net 15, your DPO shrinks by 30 days, which may double your working capital need during the first quarter.
AR discipline in B2B service
If you buy a B2B service or light manufacturing shop in London that invoices on milestones, the rhythm of billing matters more than any single customer’s credit. Move from end-of-month billing to progress billing, tighten approval workflows, and you shave 5 to 10 days off DSO without upsetting clients. In one fabrication shop, the owner billed only at shipment, even for long jobs. We revised to 30 percent deposit, 40 percent at mid-point inspection, 30 percent at delivery. DSO fell from 48 to 28 days in three months, freeing roughly 180,000 dollars in working capital against a 7 million revenue base.
Small steps work: invoice the same day as delivery, not two days later; offer a modest discount for ACH payment; use an AR analyst even part-time to chase aging buckets. Most buyers underestimate how much cash hides in lousy invoicing habits.
What the first 100 days should look like
Your goal is to avoid surprises and narrow the variance bands. Before closing, set up daily cash visibility: starting cash, receipts, disbursements, and ending cash, with a simple 13-week forecast. The forecast is not a plan; it is a windshield. Update weekly, roll it forward, and reconcile to actuals. The act of reconciliation teaches you quickly where the leaks are.
Take a practical approach to early wins. Talk to your top five suppliers in week one. Confirm terms, explain your plans, and ask what they have seen work in other accounts. For AR, segment customers into three buckets by size and payment behavior. Visit the largest, and call the rest. People pay people they know. I have watched buyers shave a full week off DSO just by making these calls and fixing broken purchase order references that delayed approvals.
Expect a dip in efficiency while you learn. Build a cash reserve for mistakes. The tidy assumption that nothing goes wrong for 60 days guarantees something will.
Tax, HST, and the often forgotten float
HST remittance can surprise a first-time buyer. In Ontario, you collect 13 percent HST on most sales, net of input tax credits on eligible purchases. If your sales outrun purchases for a period, your remittance spikes. On a retail month with strong December sales, I have seen HST take a 30,000 dollar bite in January for a mid-sized store. That is real cash. In diligence, calculate your net HST by month for the last year. Average is not enough; high months matter.
Payroll source deductions are similar. If you become an accelerated remitter due to payroll size, your payment cadence changes. Many small buyers do not budget the shift and scramble mid-month. Leave at least two pay periods’ worth of source deductions untouched until you get comfortable with the CRA cycle.
Negotiating the peg without boiling the deal
Sellers often feel the peg conversation is a gotcha. It does not have to be. State your goal clearly: you are paying for a business that can operate normally post-closing without an emergency cash infusion. That means the same level of receivables, inventory, and payables that supported recent operations, normalized for season and excluding junk. If you keep the language plain and the math transparent, friction falls.
One technique that helps: base the peg on average working capital during the last twelve months excluding the heaviest and lightest month, then adjust for seasonality relative to closing month. If you close in May for a landscaping company, you want more than average working capital because the busy season has just begun. Document any explicit carve-outs for obsolete inventory and slow AR in a schedule attached to the purchase agreement. If the seller balks, offer a holdback that releases once those items convert to cash at agreed prices or are written off.
When a great business still needs more cash than you planned
Sometimes the math says you need more working capital than your comfort level. That is not necessarily a red flag; it depends on return on working capital. If an extra 200,000 dollars keeps a line staffed and machines running at 30 percent gross margin with the ability to turn four times a year, that capital yields nicely. What you want to avoid is sticky capital: cash tied up in inventory that does not move, in AR that customers dispute, or in deposits that require additional costs to fulfill. Ask yourself: if growth slows, how quickly does this working capital return as cash? If the answer is “not for six months,” temper your growth plans until you can afford the lag.
I once watched https://www.mediafire.com/file/zwudwz8fzdg965f/pdf-68335-32021.pdf/file a buyer push too hard for growth in a custom cabinet shop on the edge of London, ballooning WIP and AR by 400,000 dollars within two months. The jobs were profitable on paper, but DSO stretched to 70 days because general contractors dragged approvals. The owner spent every Thursday morning chasing signatures. It was solvable, but the stress was unnecessary. If he had added an administrator at 55,000 dollars to shepherd paperwork and insisted on stronger deposits, he could have saved himself two hundred grand of working capital.
If you are looking at a business for sale London Ontario: sector quirks
- Hospitality: Liquor inventory is regulated and ties up cash. Staff turnover during ownership transition inflates training costs. Delivery apps distort weekly cash flow with delayed payouts and chunky commissions. Build a two-pay-period buffer plus month-one rent and utilities in cash. Home services: Dispatch and scheduling determine AR speed. Offer service agreements with prepayment to flip the cash curve. If you inherit hundreds of agreements, confirm the deferred revenue liability and the true cost to fulfill. It affects your working capital and your first-year P&L. Light manufacturing: WIP accounting can obscure real needs. Walk the floor and tag jobs by start date, stage, and expected billing date. Material cost spikes, especially in metals and components, expand dollar value sitting on shelves. Negotiate vendor locks or hedges where possible. E-commerce: Payment processors pay fast, but ad spend is pre-cash. If 30 percent of sales depend on paid ads, your cash need swings with ROAS. The cheapest working capital in e-commerce is turning off unprofitable campaigns for a week. Model that discipline before you close. Professional services: Payroll is nearly all of it. If you buy a practice that bills monthly in arrears, moving to semi-monthly billing and increasing retainer usage can free cash quickly. Be transparent with clients; small practice buyers who communicate well rarely lose accounts over better billing hygiene.
Two quick checklists that actually help
Buyer’s five-point working capital check before signing:
- Tie the working capital peg to clear definitions and a seasonally adjusted calculation, with schedules for AR aging and obsolete inventory. Map the 13-week cash flow with daily opening and closing cash, and reconcile the last four weeks to actuals. Verify supplier terms continuity in writing, and identify any deposit or guarantee requirements with landlords and utilities. Build payroll, source deductions, and HST calendars into your cash model, including accelerated remitter status if applicable. Secure a borrowing base line with realistic advance rates, plus a cash buffer equal to at least two pay periods and one rent cycle.
First 30 days after closing, in order:
- Call top suppliers and top customers, introduce yourself, confirm terms and invoice processes, and ask for feedback on past pain points. Tighten invoicing cadence and collections scripts, aiming to remove 3 to 7 days from DSO in the first month. Sweep inventory for dead or slow lines, price to move, and reinvest proceeds in faster movers. Review payroll scheduling and staffing levels, plug obvious overtime leaks, and fix approval bottlenecks. Update your 13-week forecast every Friday, annotate variances, and make one small process change each week based on what you learn.
The human side: people turn cycles into cash
You can calculate working capital to the penny and still miss the point. The people you inherit are the real lever. The office manager who knows which AP email gets you net 45 instead of net 30, the dispatcher who can smooth a Tuesday crush into a Wednesday swell, the bookkeeper who senses a customer will pay faster if you change an invoice field. Keep them. Ask them to teach you the undocumented parts of the cycle. In return, pay on time, share your cash calendar selectively, and celebrate small wins like cutting DSO by three days. Those gains compound faster than any spreadsheet curve.
If you work with a broker, choose one who respects these details. When you tap a business broker London Ontario owners recommend, listen for whether they discuss working capital early with both sides. If they talk only about multiples and top-line growth, push the conversation back to the float. That is where deals either get safer or get risky.
Bringing it together without drama
When you buy a business in London, you are buying rhythm more than assets. Working capital is the drumbeat. Know your DIO, DSO, and DPO. Anchor your peg. Build a buffer you can sleep with. Line up financing that flexes with your sales. Keep payroll sacred. Move invoices sooner, not louder. Clear dead stock. Model HST. Make friends with suppliers. Teach your forecast to tell the truth.
Do those things and the rest becomes choice, not emergency. You will have the cash to fix what needs fixing, to make better hires, to invest where returns compound, and to take a steady breath on a quiet Wednesday as the sun drops behind the forks of the Thames and your business hums into the evening, lights on in the back, bills paid, and the next day already funded.
