- The gap: a borrowing base certificate arrives monthly, but most facilities get one or two field exams a year. The months in between run on the borrower's own numbers.
- The process: real borrowing base verification is five checks: eligibility testing, dilution analysis, ineligibles and reserves, independent recalculation, and field exams.
- Who this is for: ABL lenders and agents, warehouse-facility lenders, and the credit and ops teams who decide what a certificate is worth.
A borrowing base certificate is the borrower grading its own homework. An authorized officer signs it, your team applies the advance rates, and the facility funds against the result.
That works right up until the certificate and the collateral stop describing the same company. At First Brands, the restructuring officer told the court that certificates presented to one lender did not reflect the activity recorded in the company's own systems, with initial inventory values overstated by roughly $140 million (GTR).
This guide walks borrowing base verification line by line: what the certificate contains, how eligibility and dilution testing work, where recalculation ends, and how lenders are starting to put monthly eyes on the inventory and equipment behind the numbers.
If you run credit or collateral ops on an ABL or warehouse book, you already fund against figures the borrower typed into a spreadsheet. Venta Capture, a product of VentaVid, puts sealed, timestamped visual evidence under those figures each month. Book a demo and we'll map it to one facility.
What a borrowing base certificate actually contains
Strip the formatting and almost every certificate reduces to the same worksheet. Gross collateral, minus what doesn't count, times what you'll advance against the rest.
Those advance-rate ranges are the industry's standard bands, per eCapital's borrowing base glossary. Two things about this worksheet matter more than any single line.
First, nearly every input is borrower-supplied. The A/R aging, the inventory valuation, the contra balances: they all come out of the borrower's ledger, prepared by the borrower's team.
Second, the signature is a legal instrument, not a verification. Standard credit agreements make the officer's signed certificate a representation and warranty of accuracy (sample clauses on Law Insider). That gives you recourse after a misstatement. It gives you no knowledge at the moment you fund.
Monthly submission is the norm for healthy borrowers. When liquidity tightens, agreements let lenders demand weekly or even daily certificates, which raises the reporting frequency without changing who produces the numbers.

The five checks that make up borrowing base verification
Verification is not one activity. It's a stack, and each layer catches what the previous one can't.
1. Eligibility testing
Every receivable and every pallet gets tested against the facility's definition of eligible collateral. The usual exclusions, per Ratiotech's borrowing base glossary:
- Aged invoices: commonly anything 60 days past due or 90 days from invoice date.
- Cross-aged obligors: once a set share of a customer's invoices goes bad (often 25-50%), the whole balance drops out.
- Related and offset exposure: affiliate invoices, intercompany balances, and contra accounts where the customer is also a vendor.
- Riskier obligors: uninsured foreign accounts, government receivables without an assignment of claims, disputed invoices, bill-and-hold, and anyone in bankruptcy.
- Concentration caps: typically 10-20% of the eligible pool per obligor, so one big customer can't carry the base.
2. Dilution analysis
Dilution is every dollar of receivables that gets settled with something other than cash: credit memos, returns, rebates, write-offs. It's measured as a percentage of gross sales, and it quietly tells you how honest the A/R number is.
The standard mechanics: a facility sets a dilution threshold, and sustained dilution above it costs the borrower advance rate. In Ratiotech's worked example, measured dilution of 8% against a 5% threshold cuts an 85% advance rate to 82%, which moves the base by hundreds of thousands of dollars on a $10 million ledger.
3. Ineligibles and reserves
Field examiners and credit teams propose new ineligibles as a book deteriorates. The borrower's standing objection, as ABF Journal's dilution series puts it, is that everything is already covered by the dilution reserve.
Sometimes that's true. Working out which exclusions sit inside the dilution reserve and which stack on top of it is the difference between a formula that protects the facility and one that double-counts in the borrower's favor.
4. Independent recalculation
Someone outside the borrower's finance team reruns the math: advance rates against the facility documents, caps applied correctly, reserves in place, availability recomputed before a draw funds. Third-party verification shops and in-house credit ops both do this work, and it reliably catches arithmetic drift and misapplied definitions.
What it cannot catch is a ledger that no longer matches the warehouse. Recalculation audits the spreadsheet, and a fabricated input recalculates perfectly.
5. Field exams and appraisals
The field exam is the layer that touches reality: invoice testing against shipping documents, inventory test counts, cash reconciliation. Most facilities run one or two a year, and credit agreements commonly cap routine exams at two or three annually absent a default (Law Insider).
Exams are sampled, scheduled, and expensive. One veteran examiner has argued in ABF Journal that the discipline has drifted from checking collateral toward completing work papers. Even a good exam is a snapshot.
Where self-reported numbers drift from physical reality
Put the cadences side by side and the exposure is plain. The certificate arrives monthly. The exam happens once or twice a year. A borrower on that standard setup hands you roughly eleven certificates a year that nobody checks against the physical collateral.
Between field exams, the inventory and equipment lines of a borrowing base certificate are, in practice, taken on trust. The 2025 collapses showed what can grow in that space.
At First Brands, one lender with about $230 million in inventory facilities alleged the same collateral had also been pledged to other lenders, while certificates overstated inventory purchase values by roughly $140 million according to the restructuring officer (GTR, SFNet).
At Tricolor, prosecutors allege the subprime auto lender pledged the same vehicles to multiple lenders at once and fabricated records, including fake customer payments, with losses near $1 billion according to the indictment (AP). Those are allegations, not convictions. The pattern is still the one that matters here: the paperwork reconciled, and the assets didn't.
Here's the uncomfortable part. Every layer in the previous section except the field exam works on borrower-produced data. When the drift is in the data itself, four of your five checks are checking a story against itself.
Seeing a hole like that in one of your own facilities usually starts with wanting to look, not recalculate. Book a 15-minute demo and we'll show you what a monthly look at a collateral pool can be.
The evidence layer: monthly visual verification of inventory and equipment
One correction before anything else: what follows is not borrowing base software. It doesn't test eligibility, it doesn't recalculate availability, and it shouldn't. It sits underneath the certificate and answers a different question: does the physical collateral look like the numbers say it should?
Venta Capture is guided video and photo capture built for exactly this kind of recurring verification. The lender (or the agent) sends a secure, personal capture link to the borrower's warehouse or operations staff. Whoever is already standing next to the collateral opens it in their phone's browser. No app, no account.
The difference from "email us some photos" is the guidance. Your team defines the workflow once: walk the racking in aisle order, film the bulk storage with a spoken count, photograph the serial plates on financed equipment, answer the stock-location questions. The person on site gets each step with instructions, so the right footage arrives the first time.
What lands on your desk is a structured evidence package, not a camera roll:
- Sealed on receipt. Each submission carries a SHA-256 fingerprint and a downloadable manifest, so anyone can verify later that nothing changed after it arrived.
- Visible stamp on recordings made in the session. Photos and video recorded through the link carry a date, time, and seal stamp. A gallery upload never gets one; it's labelled "Provenance: Not verified" with plain-language findings instead.
- An independent timestamp. The case is timestamped by an external authority (RFC 3161), so "when did this evidence exist" is answered by a party outside both lender and borrower.
- Session integrity signals. Changing session codes sit in the frame during recording, and devices or footage seen before raise a flag for a reviewer.
- Your reference, your structure. Submissions carry the facility or borrower reference your own system uses, with answers, transcripts, and a full activity timeline in one case.
Two honesty rules apply, and they're the same rules the product shows its users. The timestamp proves when the submission was received, not when the underlying event happened. And the integrity checks produce signals for a human reviewer, never verdicts: sealed capture raises the cost of fabricating evidence, it does not make deception impossible. A credit decision stays with your credit team.
For the equipment lines specifically, the same workflow handles equipment verification: serial plates, condition, and location on video before you rely on the line item.

How lenders fit visual verification into the monthly cycle
The cadence writes itself: attach the capture request to the certificate due date. Certificate and evidence arrive together, and the reviewer opens them side by side.
A workable monthly loop looks like this:
- Send the capture link with the certificate request. Same email, same deadline, addressed to the ops contact who is physically at the collateral.
- Request per line, not in general. For inventory: racking by aisle, bulk stock with identifiers, anything the certificate carries at a suspicious round number. For equipment: serial plate, working condition, current location.
- Review from the desk. A credit analyst compares the footage against the certificate's inventory and equipment lines in minutes, with every item timestamped and sealed.
- Escalate anomalies to the field. Treat a half-empty aisle, a declined step, or an integrity signal as a reason to ask: a question to the borrower, a retake request, or an off-cycle exam with a target.
Consistency is what makes month-over-month review useful, so hold submissions to the same standard every cycle; our guide to photo evidence standards for inspections covers what a submission needs to hold up under later scrutiny.
Two boundaries keep this honest. Visual verification narrows the gap between exams, it does not replace the field exam, the appraisal, or the receivables testing that only an examiner can do. We cover the physical side of collateral checks in our physical collateral verification guide, and the exam process itself in our field exam explainer, both separate posts.
Frequently asked questions
What is a borrowing base certificate?
It's the borrower's periodic report, usually monthly, listing eligible receivables and inventory, applying the facility's advance rates, and certifying the resulting availability. An authorized officer signs it, and that signature is a representation and warranty under the credit agreement.
Who verifies a borrowing base?
Layers of people: the borrower's officer certifies it, the lender's or agent's credit team tests eligibility and recalculates availability, third-party verification firms rerun the math independently, and field examiners test the underlying collateral on site. No single layer is sufficient on its own.
How often do lenders run field exams?
Most facilities see one or two a year, and credit agreements often cap routine exams at two or three annually outside a default. Frequency typically rises with risk: tightening liquidity or covenant pressure brings more exams and faster reporting.
What is dilution in a borrowing base?
Dilution is the share of receivables settled without cash: credit memos, returns, rebates, and write-offs. Facilities set a dilution threshold, and sustained dilution above it usually costs the borrower advance rate or adds a reserve.
Can a lender rely on borrower-submitted photos and video?
On unguided, unsealed submissions, cautiously: an emailed photo proves little about when or where it was taken. Guided capture with sealing, an independent timestamp, and integrity signals makes the evidence reviewable and verifiable, though the findings are signals for a human reviewer, never automatic proof.
Does visual verification replace the field exam?
No. It covers the months between exams with sealed, timestamped eyes on the physical collateral, and it gives the examiner targets when something looks off. Receivables testing, cash reconciliation, and formal counts remain exam work.
