The Unfunded Promise: Auditing the Operating Liabilities That Growth Leaves Behind

Growth is usually presented as a balance-sheet story: more revenue, more staff, more space. The operating story is less tidy. Expansion is often funded by quiet borrowing from the existing business — a process that was never documented, a manager carrying two roles, a control deferred until later, a customer promise sustained by familiarity rather than system. None of this appears as a liability on the balance sheet. It behaves like one all the same.

Call it growth debt. It is the accumulated operating obligation that a business takes on when it expands faster than its systems, roles and controls can absorb. The debt is real, but it is paid in interruptions, escalations, margin leakage and, eventually, failed service. For UK SMEs moving from one stage to the next, the useful question is not whether growth debt exists. It is which parts must be repaid before the next push.

Why the Bill Arrives Late

Growth conceals debt because urgency favours delivery. A small team can hold a process together through memory and proximity. A founder can approve exceptions. A finance manager can reconcile by spreadsheet. These are rational choices at a certain scale. They become liabilities when volume, geography or headcount moves the work beyond the reach of informal coordination.

The delay is dangerous. The symptoms look local — a missed deadline, a customer complaint, a key person leaving — but the cause is structural. By the time the bill arrives, the organisation may be negotiating a lease, integrating an acquisition or entering a new region. The next expansion then inherits the weaknesses of the last one.

Four Ledgers of Operating Debt

A growth-debt audit should be practical. It does not need a consulting taxonomy. It needs four ledgers, each with evidence.

Process

Look for work that depends on memory rather than method. Which steps are undocumented? Where are exceptions approved informally? Which reconciliations are manual? Which handoffs rely on a named individual? The test is simple: if volume doubled next quarter, which process would break first? Useful evidence includes rework rates, cycle times, exception logs and the number of systems touched by a single customer journey.

People

Growth debt often sits in the middle layer. Managers acquire extra reports, temporary projects and decision rights that were never formally assigned. Cover is thin. Training is postponed. The organisation may have headcount growth without management capacity. Review spans of control, vacancy cover, overtime, turnover and the number of roles with no deputy. Ask which decisions stall when one person is on leave.

Cash

Expansion consumes cash before it returns it. Longer payment terms, higher stock, work in progress and supplier deposits all borrow against future revenue. The audit should identify which commitments are being funded by supplier patience or by delaying investment. Aged debt, debtor days, cash conversion and covenant headroom matter more than the sales pipeline alone.

Customer Experience

Customer promises are a form of operating debt when they are held together by goodwill. Informal service levels, manual onboarding and named-account heroics can look like high-touch service. They become a risk when volume rises. Review complaint themes, response times, retention and the number of commitments that depend on specific staff. The question is which promises would fail if the founding team stepped away for a month.

A Simple Audit Routine

The audit should be proportionate. Define the perimeter first: one entity, one customer journey, one site or one product line. Gather evidence rather than opinion. A process map, a decision-rights table, a 13-week cash forecast and a complaint log will reveal more than a workshop of general concerns.

Then score each liability on four dimensions: likelihood of failure at the next stage of growth, impact on customers or compliance, time to fix and ownership. A simple red-amber-green rating is sufficient. The output should be a short register, not a report. Each entry needs an owner, a cost estimate and a trigger point.

Deciding What to Repay

Not all growth debt should be repaid immediately. Some borrowing is efficient. A manual process may be cheaper than automation at current volume. A stretched manager may be acceptable for one quarter. The discipline is to distinguish deliberate borrowing from unrecognised exposure.

Repay before expansion when a liability constrains capacity, creates unacceptable regulatory or customer risk, or compounds with volume. Schedule repayment when the issue can be contained and monitored. Accept the debt when the cost of fixing exceeds the cost of carrying it — but record that decision. The mistake is not having debt. It is having debt nobody has named.

Making Repayment Stick

Repayment should be built into the operating plan, not treated as a separate improvement programme. Assign owners. Set a small number of measures. Fund the work. Review it alongside sales and cash. A quarterly board review can ask a single question: what did we borrow from operations this quarter, and what are we repaying?

The aim is not to eliminate all informality. It is to stop the next stage of growth from being financed by promises the organisation cannot keep. Growth debt is a normal consequence of ambition. Auditing it is how a UK SME makes the next expansion a choice rather than a surprise.
