Working Capital Requirement

Working capital is the difference between a company's current assets (cash, receivables, inventory, and other assets expected to be converted to cash within 12 months) and its current liabilities (creditors, short-term debt, and other obligations due within 12 months). In public procurement, a working capital requirement is a financial standing assessment criterion that checks whether a bidder has enough short-term financial headroom to absorb the cash flow demands of contract performance without becoming insolvent or unable to pay subcontractors and suppliers.

What is a Working Capital Requirement?

Contracting authorities assess working capital in several ways. The current ratio (current assets divided by current liabilities) is the most common measure, with a minimum of 1.0 (meaning current assets at least equal current liabilities) being a typical threshold; some authorities set the bar at 1.2 or higher for contracts with significant upfront cost. The quick ratio (current assets minus inventory, divided by current liabilities) provides a more conservative liquidity test that excludes less liquid assets. Some authorities specify a minimum absolute working capital figure proportionate to the estimated contract value.

Article 58 of Directive 2014/24/EU allows contracting authorities to require evidence of economic and financial standing, including financial ratios. The specific ratios and thresholds used must be stated in advance, be proportionate to the contract value and complexity, and be related to the genuine financial risk of the procurement. An authority setting an excessively high working capital requirement that excludes many otherwise competent suppliers without justification risks challenge.

Working capital requirements are particularly relevant to contracts with the following characteristics. First, contracts with significant mobilisation costs that must be funded before the first payment is received. Second, contracts where interim payments are infrequent or delayed, meaning the supplier must carry costs over extended periods. Third, contracts involving advance payment guarantees, where the supplier provides financial security before receiving the advance. Fourth, contracts with retention withheld from interim payments, reducing the net cash received relative to costs incurred.

A bidder that is short on working capital has two main options. It may seek to rely on the financial resources of a parent or group entity under Article 63 of Directive 2014/24/EU, supported by a formal commitment or parent company guarantee. Alternatively, it may seek to improve its position through credit facilities before the financial standing is assessed, though banks and lenders will want to understand the procurement context before extending facilities.

Why it matters for bidders

Working capital shortfalls are a leading cause of contractor failure during public contracts. A supplier that wins a large contract but lacks the cash to fund mobilisation, pay subcontractors, and bridge the gap to first payment is at material risk of insolvency within months of starting. Contracting authorities impose working capital requirements partly to protect themselves, but also to protect the supply chain and the broader delivery programme.

Bidders should model the actual cash flow profile of the contract being tendered, not just their general balance sheet liquidity. A positive current ratio on the annual accounts may still be inadequate if the contract requires significant upfront expenditure before any payments are received.

Example

A Danish transport authority procures a five-year rail maintenance contract with an estimated annual value of EUR 6 million and significant mobilisation costs in month one. The selection questionnaire requires bidders to demonstrate a current ratio of at least 1.1 and minimum positive working capital of EUR 3 million as at the last audited balance sheet date. A bidder with EUR 5 million current assets and EUR 4.2 million current liabilities has a current ratio of 1.19 and positive working capital of EUR 0.8 million. The working capital figure fails the EUR 3 million minimum, so the bidder must consider whether it can rely on a parent entity's resources under Article 63 to supplement its own position.

Frequently Asked Questions

Can a bidder improve its working capital position between the balance sheet date and the tender submission?

Audited accounts reflect a historical position, but some authorities accept interim management accounts or bank references to demonstrate a more recent financial position. If a bidder's working capital has materially improved since the last audited accounts, it should raise this proactively in its submission and provide supporting evidence. Whether interim evidence is accepted depends on the procurement documents and the authority's approach.

How does a retention bond help with working capital?

A retention bond releases cash that the contracting authority would otherwise withhold from interim payments. This directly improves the supplier's in-contract working capital position by increasing the net cash received from certified payments. For suppliers operating on tight working capital, the cost of a retention bond is often lower than the financing cost of the withheld cash, making it a working capital management tool as well as a bond instrument.

Is working capital assessed differently for consortium bids?

For consortium bids, the financial standing assessment typically looks at the consortium as a whole or at the lead member, depending on the authority's approach. Where the authority assesses each member individually, the working capital of each member may need to meet a proportionate share of the minimum. Where it assesses the consortium collectively, the aggregate financial position is considered. The procurement documents should specify the approach; if they do not, bidders should seek clarification.
