What is a bill-only PO?
In medical device distribution, a bill-only purchase order is how hospitals pay for products that were already on-site when they were used in surgery. No shipment. No receiving dock. Just billing — and it's where most of the complexity lives.
The short version
Medical device companies place inventory at hospitals and surgery centers before procedures happen — as consignment stock or in a rep's trunk. When a surgeon uses a device, the hospital owes the distributor for what was consumed. The bill-only PO is the mechanism that triggers that payment.
It's called "bill-only" because the distributor is billing for product that has already been delivered and consumed. There's no corresponding shipment to match against — just a case record from the field and a purchase order from the facility.
This model is standard across orthopedics, spine, trauma, cardiovascular, and most implantable device categories. For many distributors, bill-only orders represent 60-80% of total revenue.
How a bill-only order works
From surgery to collected payment, here's the lifecycle of a typical bill-only transaction.
Surgery happens
A medical device is implanted or used during a surgical procedure at a hospital or ambulatory surgery center.
Rep records usage
The field rep documents which devices were used — product codes, lot numbers, quantities — typically via text, email, or a case form.
Hospital issues a bill-only PO
The facility generates a purchase order specifically for the devices consumed in that case. No physical shipment is required — the product is already on-site.
Distributor matches and invoices
The distributor matches the PO to case utilization, validates pricing against the facility contract, and generates an invoice.
Payment and reconciliation
The facility pays the invoice. The distributor reconciles payment, updates inventory levels, and triggers replenishment for consumed stock.
Bill-only vs. stocking orders
Medical device distributors process two fundamentally different order types — and they require different workflows.
| Bill-Only | Stocking | |
|---|---|---|
| Trigger | A completed surgical case | Inventory below par level |
| Product location | Already at the facility (consignment or trunk stock) | Shipped from warehouse to facility |
| Physical shipment | None — product was consumed on-site | Yes — product is physically delivered |
| PO timing | After surgery, sometimes days or weeks later | Before or concurrent with delivery |
| Matching requirement | Must match PO to case utilization record | Must match PO to shipping/receiving record |
| Revenue complexity | High — contract pricing, GPO tiers, facility-specific rates | Moderate — typically standard catalog or contract pricing |
Why bill-only processing is so painful
Bill-only is where medical device revenue goes to wait. Here's what teams deal with every day.
30-60 day billing lag
When POs arrive by email or fax and sit in a queue, revenue recognition can lag surgery by weeks. Cash tied up in unbilled cases compounds across hundreds of orders per month.
8-12% credit and rebill rate
Manual pricing lookups against complex contract matrices lead to invoicing errors. Each credit-rebill cycle costs $50-150 in admin time and damages facility relationships.
Billing team bottleneck
Most billing teams spend 80% of their time on routine data entry — typing PO line items into the ERP, cross-referencing case records, hunting down missing information from reps.
Audit and compliance risk
Without a clear trail from surgery to invoice, companies struggle to document pricing accuracy, contract compliance, and inventory chain-of-custody during audits.
What modern bill-only processing looks like
The traditional bill-only workflow — printing POs, manually keying line items, cross-referencing contracts in spreadsheets — was designed for a world with fewer SKUs, simpler contracts, and smaller case volumes. That world no longer exists.
Modern bill-only automation detects incoming POs from any channel, extracts line item data, matches it to the rep's case record, validates pricing against the correct contract tier, and generates an invoice — all without a human touching the routine orders. Your billing team only sees the exceptions that actually need judgment.
The result: same-day invoicing instead of a 30-60 day lag. Credit-rebill rates under 2% instead of 8-12%. And a billing team that spends time on collections and exceptions instead of data entry.

What does your bill-only processing actually cost?
