Custody Without Title: A Consignment Reconciliation Framework for Specialty Clinics

Specialty clinics often turn to consignment stock and vendor-managed cabinets when high-cost implants, biologics, or procedure-specific kits would otherwise tie up cash and shelf space. The appeal is straightforward: the vendor places inventory near the point of care, and the clinic pays when an item is used. Yet the arrangement creates a custody relationship that is easy to describe and hard to govern. When an expired box sits on a shelf and the vendor report disagrees with the physical count, the clinic can discover that free stock has become an unaccounted liability.

Define Ownership Before Counting Units

Consignment is not a donation, and it is not ordinary stock. In a typical arrangement, the vendor retains title until a defined trigger—use on a patient, transfer to a procedure tray, or invoicing. The clinic holds custody before that trigger. The contract should state the title-transfer point, who bears risk of loss, who insures the stock, and who is responsible for storage conditions. Without those terms, a damaged or expired unit can become a dispute rather than a credit.

Vendor-managed cabinets add another layer. The vendor may own the software, the scanner, or the replenishment logic, while the clinic owns the physical space and the obligation to report usage. Clinics should also distinguish consignment from loaner kits, demo units, and bill-only items. Each category needs a label on the shelf and a line in the reconciliation. Mixing them is the fastest route to double billing.

The Four Records That Must Agree

A defensible audit compares four records: the physical count, the vendor consignment report, the clinic usage record, and the purchase or credit ledger. The physical count confirms what is present. The vendor report states what the vendor believes it owns. The usage record shows what was consumed. The ledger shows what was billed, credited, or returned.

Discrepancies usually fall into predictable patterns. A unit is used but not reported. A lot expires and remains on the shelf. A loaner is counted as consignment. A return is shipped but not credited. A case pack is counted in eaches while the vendor reports cases. Reconciliation should be scheduled, not improvised—weekly for high-turnover cabinets, monthly for slower specialty items—and assigned to a named inventory steward.

Expiration Is a Shared Risk

Expiration terms deserve more attention than they often receive. The contract should specify who removes short-dated stock, how much notice the vendor must give, and who absorbs the cost when an item expires in custody. Clinics should set a minimum remaining shelf life at delivery and reject stock that arrives below it. Expired units should be quarantined immediately, labeled, and removed from the active count. A vendor report that quietly ages out an expired box is not a reconciliation; it is an omission.

Usage Reporting Triggers the Invoice

Consignment frequently operates on a bill-on-use basis. That makes usage reporting a financial control, not a clerical task. Each consumption record should capture the item, quantity, lot or serial number, date, patient encounter or case identifier, and the clinician who used it. Barcode scanning reduces transcription errors, but the clinic still needs a monthly attestation that reported usage matches the reconciliation.

Vendor access to clinic systems should be limited to the minimum necessary data. If the vendor manages a cabinet, the agreement should define who can view patient-adjacent information, how long data is retained, and what happens when the relationship ends. Usage data is not only an inventory record; it is part of the clinic's operational history.

A Practical Reconciliation Checklist

Use the following checklist to match physical counts to vendor reports and to keep custody from drifting into ambiguity.

• Assign every storage location a unique identifier and label each shelf as clinic-owned, consignment, loaner, or demo.
• Count on a fixed schedule with two people present; record the date, time, counters, and cabinet identifier.
• Match items by item master, unit of measure, lot, serial number, and expiration date—not by description alone.
• Reconcile the vendor report to the physical count and the usage log; investigate every variance above a defined threshold.
• Confirm that expired or quarantined units have been removed and credited.
• Verify that loaner and demo items are not commingled with consignment stock and that return dates are tracked.
• Review open purchase orders and bill-only transactions for duplicate billing.
• Check that received stock met the minimum remaining shelf-life requirement.
• Reconcile returns, restocking fees, and credits against shipping records.
• Document variance resolution, assign corrective actions, and obtain signatures from clinic and vendor representatives.
• Review the consignment agreement annually, including insurance, audit rights, and termination inventory obligations.

Set Thresholds and Consequences

A reconciliation without thresholds becomes an argument about every unit. The agreement should define acceptable variance by dollar value or unit count, an escalation path for unresolved differences, and the vendor's obligation to provide a corrected report within a stated period. Clinics should also reserve audit rights and require the vendor to participate in a physical inventory at least annually and at termination.

Consignment can reduce cash-flow pressure and free clinical space, but it does not eliminate inventory risk. It redistributes that risk in ways that must be documented. The useful question is not who owns the shelf. It is who owns the process for proving what is on it. In 2026, specialty clinics that answer that question in writing will be better positioned to keep consignment stock from becoming an unaccounted liability.
