Eligible vs ineligible receivables: the rules that decide your real borrowing power

Your balance sheet says $22 million of receivables. Your borrowing base certificate says you can borrow against $16.7 million of them. Nobody stole the other $5.3 million. It failed a test. Every receivables facility draws a line through your AR, and only the invoices on the right side of that line count as collateral. Most CFOs can quote their advance rate from memory. Far fewer can explain where a quarter of their receivables went, which is a problem, because the eligibility rules move more money than the advance rate does.

The tests, in the order they usually run

The exact list lives in your agreement, but most facilities apply a familiar core set. Each test is mechanical, which is good news: mechanical rules can be computed deterministically and checked before your lender checks them.

• Aging. Invoices beyond a cutoff, commonly 90 days from invoice date or 60 days past due, are ineligible. The single largest exclusion for most borrowers.
• Cross-aging. If a threshold of one customer's balance is past the cutoff, often 25 to 50 percent, the entire customer becomes ineligible, current invoices included.
• Concentration. Balances above a per-obligor cap, commonly 10 to 20 percent of eligible AR in ABL, are excluded as excess.
• Obligor type. Affiliates and intercompany balances are almost always out. Government receivables are commonly excluded unless assignment of claims steps are taken. Individual consumers are often out too.
• Jurisdiction. Foreign obligors are frequently ineligible unless insured or backed by letters of credit, and many agreements carve out specific approved countries.
• Disputes. An invoice the customer is actively contesting does not count, regardless of age.
• Contras. If a customer is also your supplier, the amount you owe them offsets what they owe you, and that overlap is excluded.

The tests also interact, and the interactions are where availability disappears without warning. One aging invoice can push a customer past the cross-aging threshold, which pulls their current invoices out too. Removing a mid-sized customer from eligible AR shrinks the base that concentration caps are measured against, which can push another customer into excess. This cascade is why the calculation order in your agreement matters, and why running the tests in a spreadsheet, in whatever order the tabs happen to sit, produces certificates that disagree with your lender's recomputation.

A worked example: from $22 million to $16.7 million

Here is how the tests stack up on a realistic mid-market book. Each line is a separate rule, and each rule removes specific invoices you can list.

At an 85 percent advance rate, this book supports a $14,195,000 borrowing base before reserves. Now run the counterfactual: cut the aging and cross-aging exclusions in half through better collections, and eligible AR rises by $1,250,000, which is about $1,060,000 of extra availability. No new sales required, no amendment, no fees. Compare that to what a one point improvement in the advance rate would take to negotiate, and the priority becomes obvious. That is the argument for treating ineligibles as a managed number instead of an output someone reads off a certificate once a month.

Every exclusion should trace to specific invoices

A certificate line that says cross-aged obligors, $900,000 is a claim. The support for that claim is a list: which customers tripped the threshold, which invoices make up their balances, and what percentage of each balance was past due on the cutoff date. Field examiners test exactly this. They pick an ineligible category, ask for the detail, and trace it to the subledger. If the answer is a hardcoded cell in a spreadsheet, the exam gets longer and the lender gets more conservative.

Traceability is also what makes disagreements resolvable. When your lender questions why concentration ineligibles doubled, the difference between a tense call and a two-line email is whether you can show the invoices behind both months. Source-level lineage from every certificate line back to the records that produced it is the whole game.

We have watched this play out in field exams more than once. The examiner asks for the detail behind a $900,000 ineligible line. Team A produces an invoice list in ten minutes, the exam moves on, and the report notes strong collateral reporting. Team B spends two days rebuilding the number from an old spreadsheet, gets to $860,000, and cannot explain the $40,000 gap. Nothing was wrong with Team B's receivables. But their next facility renewal priced in the uncertainty anyway, through a tighter cap here and an extra reserve there. Documentation quality is not cosmetic. It compounds into terms.

How do you keep ineligibles low?

Some exclusions are structural. If 20 percent of your revenue is foreign and your agreement excludes foreign obligors, that is a negotiation for the next amendment, possibly with credit insurance as the unlock. But in our experience the biggest categories respond to operational discipline within a quarter or two.

• Billing hygiene. Wrong PO numbers, missing backup, and misaddressed invoices add 15 to 30 days to payment cycles and push balances toward the aging cliff.
• Fast cash application. Cash sitting unapplied for a week makes paid invoices look old. Same-week application keeps the aging honest.
• Dispute resolution with a clock on it. A dispute resolved in 20 days costs you one certificate cycle. A dispute that drifts for 95 days costs you the invoice and can trigger cross-aging on the whole customer.
• Credit memo speed. Issuing credits promptly keeps dilution visible and predictable instead of arriving in one lumpy, reserve-inflating batch.
• Watching concentration before month end. If one customer is trending past its cap, you can prioritize collecting that name specifically.

Teams that compute eligibility continuously, rather than discovering it at month end, consistently run lower ineligible percentages, because problems get caught while they are still fixable. That is the operating model Olycor is built around: eligibility rules run deterministically against live receivables data, so the certificate is a confirmation, not a surprise.

Your advance rate is negotiated once a year. Your ineligibles are negotiated every day, by your operations.
