Every business manages its payables to some degree — paying on day forty instead of day thirty is not a red flag by itself. What matters to a buyer is the pattern and the degree: a business that has stretched its suppliers because it has to, not because it chooses to, has been quietly borrowing from people who did not agree to lend.
Key takeaways
Deavo’s own due diligence checklist for first-time buyers names it directly: financial due diligence covers two to three years of historical financials plus a current-year interim, tax and GST/HST filings checked against the statements, a normalized earnings summary with add-backs explained, (AR/AP aging), and outstanding loans, leases or liens against assets (deavo, due diligence checklist). Payables aging sits in the same category as receivables aging for a reason — both describe how a business actually manages cash, not just what its income statement says it earns.
Sequencing matters too: the same checklist recommends financial due diligence run first, because if the underlying numbers do not hold up, there is little reason to spend time and legal fees on the operational and legal review that follows (deavo).
A payables aging report sorts what the business owes suppliers by how overdue each invoice is — the same structural technique buyers apply to a target’s receivables, applied in reverse. Where a business consistently pays on the terms its suppliers set, aged payables are a non-event. Where the aging shows a growing share of invoices sitting well past their due date, that is different: it usually means the business is using unpaid supplier balances as a source of working capital, whether deliberately or because it has no other slack left.
The distinction matters because stretched payables flatter reported cash on hand without flattering the business’s underlying earnings — unpaid invoices have not yet left the bank account, so a business funding itself this way can look more liquid at the exact moment it is quietly running low on supplier goodwill.
Reading a target’s financial statements involves checking for “a gap between what is reported on the financial statements and what was filed with the CRA or reported for GST/HST” (deavo, reading financial statements) — a flag built for revenue and general reporting integrity, and one that applies just as directly on the payables side: input tax credits claimed against supplier invoices should reconcile with what those invoices actually show as outstanding or paid. Records supporting that reconciliation have to exist under the Income Tax Act’s own retention rule — books and vouchers “necessary to verify the information contained therein” must be kept for six years from the end of the relevant taxation year (ITA s. 230(4)(b)), so the underlying documents to check against should be available on request.
The structure of the deal decides whether stretched payables even become the buyer’s problem. In an asset sale, “the corporation sells specific assets… and the buyer typically picks which liabilities, if any, come along” (deavo, tax planning before you sell) — a buyer can decline to assume disputed or badly aged supplier balances and leave them with the seller to settle before or after closing. In a share sale, the buyer takes on the corporation as a whole, “including its history and any liabilities that were not specifically excluded in the purchase agreement” (deavo) — aged payables come along by default unless the agreement carves them out.
Payables are one half of the same working capital mechanics that receivables and inventory feed into. Buyer and seller typically agree a target working capital amount before closing based on the business’s recent historical average (treadstonelaw, working capital adjustment) — and a business that has stretched its payables in the run-up to a sale can show an artificially favourable net working capital position on exactly the measurement date that matters most, since low, stretched payables reduce what the business appears to owe. This is precisely why representations about the accuracy of closing figures matter alongside the adjustment mechanism itself: a seller can be asked to represent that the closing working capital figures are prepared consistently with the business’s stated accounting policies, giving the buyer both the adjustment mechanism and, separately, an indemnity claim if that representation later proves false (treadstonelaw, seller guarantees on working capital figures).
A supplier relationship built up over years sometimes rests on more than the corporate agreement on paper — a founder personally guaranteeing a supplier credit line is common in small businesses, and stretched payables can be a sign that a supplier has been extending informal grace specifically because of that personal relationship, not because the business’s credit on its own merits would support the same terms. Confirming whether any supplier arrangement depends on a guarantee the seller will no longer be providing after closing is a separate check from the aging report itself, and one that can matter more than the dollar figures if a key supplier’s terms were never really extended to the corporation at arm’s length in the first place.
To illustrate the mechanics only — the figures are a scenario, not a benchmark — a target’s payables aging shows $180,000 current, $60,000 at 31–60 days, and $95,000 over 90 days, against supplier terms that call for payment within 30 days. The over-90 balance alone is roughly a quarter of total payables, concentrated with three suppliers who have recently begun requiring prepayment on new orders — itself a signal worth confirming directly, since a supplier tightening its own terms is reacting to something.
In an asset purchase, the buyer structures the offer to exclude the over-90 balance entirely, leaving the seller to settle it from sale proceeds before release of any holdback, rather than assuming a liability the buyer had no part in creating. Checking further, the buyer learns the business’s largest supplier line has been running on the founder’s personal guarantee for eleven years — a fact not visible anywhere in the payables aging itself, and one the buyer now has to resolve directly with the supplier before closing, since that guarantee will not transfer with the sale.

No — moderate, consistent use of full supplier terms is ordinary cash management. What matters is the trend and the degree: a growing share of significantly overdue balances, or suppliers tightening their own terms in response, is a different signal than routine 30-to-45-day payment timing.
Generally yes, subject to how the purchase agreement is drafted — an asset purchase lets the buyer choose which liabilities transfer, which is one of the structural reasons buyers often prefer it over a share purchase where liabilities come along by default.
The target’s own GST/HST filings and underlying supplier invoices, which the Income Tax Act requires the business to retain for six years — request the source documents, not just the aging summary.
The timing and manner of any post-closing payment obligation, including how it interacts with a working capital adjustment, is something buyer and seller can negotiate and write into the purchase agreement — but it is best settled during the original negotiation, not proposed after the figures are already final.
