Glossary

Key terms used throughout this guide

Bill-Only Order: An order created after a product has already been used in surgery. The device was consigned or trunk stock — billing happens post-procedure, not at shipment.

Consignment Inventory: Manufacturer-owned product placed at hospitals, surgical centers, or in rep vehicles. The manufacturer retains ownership until the device is implanted or used.

Stock / Direct Order: A traditional purchase order where the customer orders product in advance and takes ownership upon delivery.

Trunk Stock: Inventory carried in a field rep's vehicle for immediate surgical availability. Typically the least visible and hardest to track category of field inventory.

Case Sheet: The surgical record listing every device implanted or used during a procedure. Often handwritten or scanned — the primary source document for bill-only orders.

Purchase Order (PO): A formal document from a hospital or GPO authorizing the purchase of specific products at contracted prices.

UDI (Unique Device Identifier): An FDA-mandated barcode system for tracking medical devices from manufacturer to patient. Required for regulatory compliance and recall execution.

DSO (Days Sales Outstanding): The average number of days between invoicing and receiving payment. A key measure of revenue cycle efficiency.

Revenue Recognition: The accounting event where product usage is recorded as revenue. In medical devices, this often lags 30–60 days behind actual implantation.

Par Level: The minimum quantity of a product that should be maintained at a specific location to meet anticipated surgical demand.

ERP (Enterprise Resource Planning): The backend system managing inventory, orders, and accounting. Common platforms include Microsoft Dynamics Business Central, NetSuite, and SAP.

1099 Rep: An independent sales representative contracted (not employed) by a manufacturer. They often carry multiple product lines and operate with minimal corporate system access.

GPO (Group Purchasing Organization): An entity that negotiates purchasing contracts on behalf of hospital networks. Contract pricing flows through GPO agreements.

Virtual Kit: A Deviceflow feature that lets reps order instruments as a single kit while the 3PL ships individual items with lot-level tracking. Deviceflow reassembles the items into a virtual kit, preserving both ordering simplicity and full traceability.

Preference Card: A surgeon-specific list of preferred implants, instruments, and supplies for a given procedure type.

Inventory Variance: The gap between what your ERP says you have in the field and what's actually there. Typical variance in medical device: 10–20%.

Credits & Rebills: Corrections issued when an invoice contains the wrong product, price, or quantity. A direct symptom of manual order entry errors.

Section 01

Why order-to-cash is broken for medical device commercial teams

Medical device companies don't have an ERP problem. They have a last-mile problem.

ERPs like Dynamics Business Central, NetSuite, and SAP handle warehouse inventory, accounting, and financial reporting well. But 60–80% of medical device inventory sits outside the warehouse — in hospital consignment closets, surgical center stockrooms, and rep vehicles. The ERP can't see it, and customer service can't process what they don't know about.

The result: order-to-cash runs on emails, texts, phone calls, and spreadsheets. Field reps cobble together orders across 6+ apps. Customer service teams re-key the same data 3–4 times. Finance discovers revenue 30–60 days after the product was implanted.

30–60

Days consignment usage reporting delay

15–20

Min per order manual entry

8–12%

3–5

The hidden costs nobody budgets for

1

Revenue recognition delay

Consignment usage goes unrecorded for weeks. Finance can't recognize revenue they don't know about — $200K–$500K sits unbilled every quarter.

2

Customer service bottleneck

A team of 3–5 people manually re-keys orders from emails, faxes, and phone calls. They're the single point of failure for your entire revenue cycle.

3

Field inventory black hole

$2M+ in consigned and trunk stock inventory with less than 50% location accuracy. Expired product gets implanted. Audits become fire drills.

4

Rep productivity drain

Sales reps spend 40% of their week on admin — checking inventory, chasing approvals, re-entering data. That's selling time you're paying for but not getting.

These aren't technology problems. They're process gaps that exist between your ERP and the field — and they compound as you add reps, territories, and product lines.

Section 02

The three order types — each with unique complexity

Every medical device commercial team processes three fundamentally different order types. Each has a different trigger, a different data source, and a different failure mode. Most teams use the same manual process for all three — which is why errors compound.

Stock / Direct Orders

Customer orders product in advance

The hospital or distributor sends a PO — by email, fax, or portal. Customer service re-keys it into the ERP, cross-referencing contract pricing, checking inventory availability, and confirming ship-to addresses. A single PO with 15 line items takes 15–20 minutes to process manually.

What breaks:

Wrong item numbers transcribed from handwritten POs. Incorrect pricing applied because contract lookup is manual. Duplicate orders entered when reps follow up by email and phone.

Consignment

Manufacturer-owned inventory used at the point of care

Product sits at hospitals and in rep vehicles until it's implanted. The rep reports usage — sometimes the same day, sometimes weeks later. Customer service creates a bill-only order, reconciles against contract pricing, and adjusts inventory counts. Meanwhile, finance has no visibility into the revenue until the paperwork surfaces.

What breaks:

Usage reported late or not at all. Inventory counts drift from reality. Revenue recognition lags 30–60 days. Product expires in the field without anyone knowing.

Bill-Only

Product used first, billed after

After surgery, someone — a rep, a nurse, a materials manager — sends a case sheet listing what was used. That case sheet arrives by text, email, fax, or hospital portal. Customer service matches it to a PO, verifies pricing, and creates the invoice. If anything doesn't match, the cycle restarts.

What breaks:

Case sheets are incomplete or illegible. No PO on file triggers a multi-day chase. Pricing mismatches cause credits and rebills on 8–12% of invoices. Every correction adds 5–10 days to the cash cycle.

The common thread: every order type depends on information that originates in the field, passes through multiple hands, and gets manually re-entered into the ERP. Each handoff is a chance for delay, error, or data loss.

Section 03

Day-to-day process: what changes

Automation doesn't replace your team — it removes the manual steps between field activity and ERP data entry. Here's what the workflow looks like today vs. with Deviceflow, broken down by order type.

What your team does differently

Deviceflow doesn't eliminate roles — it changes what people spend their time on. Customer service shifts from data entry to exception handling. Reps go from chasing approvals to selling. Finance moves from reconciliation to analysis.

Customer Service

Before: Re-keying orders all day

After: Reviewing AI-processed orders, handling exceptions and customer escalations

Field Sales Reps

Before: 40% of week on admin work

After: Text-based ordering, real-time inventory checks, territory analytics on demand

Finance

Before: Chasing revenue recognition

After: Same-day revenue visibility, clean data for forecasting, audit-ready records

Section 04

A day in the life of a rep

Most medical device reps and distributor agents aren't opposed to technology. They're opposed to technology that adds steps. Here's what a rep's day looks like with Deviceflow — and what it means for the people supporting them.

The rep's workflow

Today

1 Finishes surgery, heads to next case

2 Snaps a photo of the case sheet (maybe)

3 Texts or emails CS “we did this case” days later

4 CS calls back for missing lot numbers, quantities

5 Calls warehouse to check if inventory shipped

6 Follows up on PO status by email — again

Admin time: 40% of the week

With Deviceflow

1 Finishes surgery, gets nurse signature on phone

2 Texts or uploads the case sheet — done in 60 seconds

3 AI extracts products, lot numbers, and patient info

4 Inventory auto-adjusts, delivered order form sent to facility

5 Rep checks trunk stock, order status, and billing — all from their phone

Admin time: Under 5 min/case

What changes for the people behind the rep

Back-Office / CS

Stops re-keying orders from texts and emails. Structured data arrives automatically — they review exceptions instead of transcribing everything from scratch.

3PL / Warehouse

Gets structured, consistent fulfillment requests instead of free-form emails. Shipping notifications flow back into Deviceflow automatically — no manual inventory reconciliation.

Manufacturer / HQ

Real-time visibility into field activity across every agency and territory. See every order, every shipment, and every bill-only without calling anyone.

Virtual kits: lot-level visibility without losing kit convenience

3PLs face a tradeoff: kit instruments into a single box (convenient, but you lose lot-level tracking) or ship items individually (full traceability, but reps manage five line items instead of one). Deviceflow’s virtual kits solve this. Reps order a single kit. The 3PL ships individual items with lot numbers. Deviceflow reassembles them into a virtual kit — so you get lot-level visibility, full compliance traceability, and a rep experience that feels like ordering one thing.

Section 05

Implementation: go-live in 4–6 weeks

Deviceflow deploys alongside your existing ERP — not instead of it. There's no data migration, no system replacement, and no multi-month IT project. Your ERP stays your system of record. Deviceflow handles everything between the field and the ERP.

What you don't need

No app downloads. No classroom training. No change management initiative. No IT project plan. Reps work through SMS — the same channel they already use to communicate with customers. Operations gets a web dashboard. Everything syncs to your ERP in real time.

Section 06

Compliance that runs itself

If you manufacture surgical implants in the United States, the FDA requires you to track every device from production through implantation. Not as a best practice — as a legal obligation, with civil penalties of $10,000–$20,000 per violation. Most growing manufacturers know this. Most also know their records have gaps.

What the FDA actually requires

1

Lot & serial traceability — 21 CFR 820.65

Manufacturers of surgical implants and life-sustaining devices must assign a control number (lot, batch, or serial) to every unit of finished device and maintain traceability records in the Device History Record (21 CFR 820.184). Records must be retained for the design life of the device — for implants, that’s effectively forever.

2

Device tracking — 21 CFR Part 821

The FDA can issue a tracking order for any Class II or III implant. When they do, manufacturers must produce patient-level tracking data — device identifier, lot number, patient name, implanting physician, facility, and date — within 10 working days of an FDA request. Without a system, that’s a scramble that turns into an enforcement action.

3

Recall reporting — 21 CFR Part 806

Written report to the FDA within 10 working days of initiating any correction or removal that reduces a health risk. You must also keep records of all corrections and removals — even ones you don’t report. That includes root cause, scope, and an effectiveness assessment.

4

UDI labeling — 21 CFR 801.20

Every device label must carry a Unique Device Identifier with a Device Identifier (product) and Production Identifier (lot number, serial number, expiration date). Manufacturers submit to GUDID, the FDA’s global device database.

How Deviceflow automates compliance

Every transaction that flows through Deviceflow — orders, shipments, bill-onlys, inventory transfers, returns — creates a complete, timestamped compliance record without anyone doing extra work.

Lot tracking from receipt to implant

Lot numbers are captured automatically from 3PL shipping notices, assigned to rep trunk stock, and linked to the patient record when a bill-only is submitted. The full chain of custody — 820.65 traceability — is built as a byproduct of normal operations.

Patient-level device tracking

Every bill-only records which device (lot and serial), which facility, which patient, which physician, and which date. If the FDA issues a Part 821 tracking order, the data is already there — exportable in seconds, not reconstructed over days.

Expiry & field inventory visibility

Deviceflow tracks expiration dates across every field location. Product nearing expiry in a rep’s trunk or a hospital consignment closet triggers automatic alerts — before it gets implanted or written off.

Recall execution in minutes

If a lot needs to be recalled, Deviceflow shows exactly which units are in the field, where they are, and whether they’ve been implanted. Part 806 requires a written report within 10 working days — you’ll have the data within 10 minutes.

Section 07

Section 08

The value: what automation actually delivers

Based on a mid-market medical device commercial team processing 200–500 orders per month across all three order types.

Annual impact model

Metric	Before Deviceflow	With Deviceflow
Time to invoice (consignment)	30–60 days	Same day
Order entry labor	3–5 FTEs @ $55K avg	1 FTE reviewing exceptions
Credits & rebills	8–12% of invoices	< 2% of invoices
Revenue recognition delay	$200K–$500K unbilled/qtr	Billed within 24 hours
Field inventory accuracy	< 50% location visibility	97% real-time accuracy
Rep admin time	40% of selling week	< 10% with SMS workflows
Estimated annual savings		$250K–$600K+

Where the ROI comes from

Staffing efficiency

Reduce order processing headcount from 3–5 FTEs to 1. Redeploy team members to customer-facing work. Scale 50% without adding operations staff.

Revenue acceleration

Same-day revenue recognition for consignment. 15–30 day reduction in DSO. $200K–$500K in previously unbilled quarterly revenue captured immediately.

Error reduction

Credits and rebills drop from 8–12% to under 2%. Each avoided correction saves 5–10 days of cash cycle time and eliminates customer friction.

Inventory control

25% improvement in inventory turns. 25% reduction in write-offs from expired product. Real-time visibility eliminates emergency logistics scrambles.
