One qualified supplier: financing a single-source input
A producer with one qualified feedstock supplier is not a supply-chain problem. It is a credit structure. This note sets out the covenant that pays a borrower to hold inventory, and the ring-fenced line that puts a second supplier on a schedule.
Key points
Where one supplier is qualified, the supply agreement must outlive the facility that relies on it.
A cover covenant pays a borrower to hold inventory that a turnover covenant would penalise.
Ring-fencing the qualification cost inside the facility puts a second source on a dated schedule.
A specialty materials producer with one qualified supplier for its principal feedstock presents a credit structure rather than a procurement difficulty. Qualification of a second supplier in this sector takes between 18 and 30 months, runs through customer approval as well as the producer's own testing, and cannot be accelerated by paying more for it. Until that second source exists, debt service depends on a counterparty the borrower does not control and cannot replace inside the tenor of most facilities.
Commercial Finance sized a US$24 million revolving facility for such a producer in the second quarter of 2025 against inventory cover rather than against receivables. The borrower holds 140 days of feedstock. The facility requires a minimum of 90 days of cover, tested monthly on a certificate signed by the operations director, with a step-down in availability rather than an event of default if cover falls between 60 and 90 days. Below 60 days the facility stops lending and the borrower reports weekly.
Inventory finance normally discourages inventory. An advance rate against receivables rewards a borrower for turning stock into invoices quickly, which is the opposite of what a single-source producer should be doing. This structure therefore prices cover rather than turnover. The margin falls by 15 basis points for every further 30 days of cover held above the covenant, to a stated floor. The borrower is paid to carry a risk the lender would otherwise carry, and the arithmetic is written into the facility so both sides can see it.
US$3.5 million of the commitment is ring-fenced for qualification of a second supplier and can be drawn only against milestones: sample acceptance, pilot batch, customer approval and first commercial delivery. The margin steps down by 75 basis points on the fourth milestone. That step-down is worth about US$180,000 a year at full utilisation, which is a fraction of the qualification cost and is not the reason a borrower does the work. It is the reason the work gets a schedule and a name against it.
The division also runs diligence on the supplier as though the supplier were the borrower: ownership, financial condition, site concentration and the term of the supply agreement. In this case the supply agreement had 26 months left to run against a facility tenor of 48 months. That mismatch was closed before signing by extending the supply agreement to 54 months, which cost the borrower a price concession and cost the lender nothing at all.
Three commercial finance positions in the group carry a single-source input of this kind, and all three are structured the same way: cover covenants instead of turnover covenants, a ring-fenced qualification line, and a supply agreement that outlives the facility. None has drawn the availability step-down. The structure is not a general view about supply chains. It is an answer to a specific arithmetic in which the cheapest available security is the stock the borrower already holds.
