Traceability Software: A Buyer's Guide to Capabilities You Can Test
Which rule applies depends on what you make. What to test does not: a live trace of your own messy lot, from receipt to customer.

In Short
- Food, devices and drugs have different traceability rules.
- Capture events when they happen, by scan.
- Judge vendors on a live trace, not a feature list.
Inventory & Traceability: the Practical Operations Guide
From goods-in to dispatch: practical controls for locations, usable stock, movements, counting, picking and traceability. Use it with or without V5.
- Follow a lot both ways.
- Reconcile a trace before acting on it.
- Run a timed trace exercise.

Inventory & Traceability: the Practical Operations Guide
From goods-in to dispatch: practical controls for locations, usable stock, movements, counting, picking and traceability. Use it with or without V5.

Traceability software should answer two questions quickly and with evidence: where did this lot come from, and where did it go? Which rules apply depends on what you make and where you sell it. This guide covers what traceability software does, the main rules by product type, capabilities to test, where it pays back and common buying mistakes.
What traceability software does
It records lots, or serial numbers where required, at each event: receiving, production, packing, storage and shipping, with quantities, dates, locations and trading partners. It links inputs to outputs so a person can trace backward from a finished lot and forward from an input.
More on what traceability software does
It produces trace reports and helps place affected stock on hold. Better systems record these events when they happen, by scanning, rather than reconstructing them later.
Which rules apply to which products
Food in the US: records under 21 CFR Part 1 Subpart J for most food businesses, and the Food Traceability Rule (Subpart S) for foods on the Food Traceability List. Food in the EU: Regulation 178/2002 Article 18, one step back and one step forward.

Product tracing and serialisation for US prescription drugs.
More on which rules apply to which products
Medical devices: Unique Device Identification under 21 CFR Part 830 and labelling under 801 Subpart B, plus traceability under ISO 13485. Prescription drugs in the US: product tracing and serialisation under the Drug Supply Chain Security Act. Check each rule's current scope and dates on the regulator's own page.
Capabilities to Test
Scan-based capture at receiving, production and shipping. Handling of splits, blends, rework and relabelled product.
Live-Trace Test Script
More on capabilities to Test
Forward and backward trace with quantities and a clear report. Holds placed from a trace result. Customer and supplier records linked to each shipment and receipt. Export in the formats your regulators or customers ask for. Where you need them, GS1 identifiers and serial numbers.
Where it pays back
Faster, narrower recalls, because you can identify exactly which lots and customers are affected. Less time spent answering customer and audit traceability requests.
More on where it pays back
Fewer write-offs from holding more stock than necessary. Measure your current mock-recall time and scope before buying so you can compare.
How to evaluate vendors
Give each vendor the same real scenario, including a reworked lot and a partial shipment, and ask them to trace it live. Ask how data is captured on your floor, which devices are needed, and how the system connects to ERP and to customers.
More on how to evaluate vendors
Ask for an export of the trace.
Common Mistakes
Buying on a feature list without a live trace. Capturing lots at the end of the day.
More on common Mistakes
Ignoring rework and repack. Forgetting the shipping step. Not rehearsing the recall procedure that uses the software.
Questions
What is the difference between traceability and serialisation?
Traceability usually tracks lots. Serialisation identifies individual units, which some rules require.
Is the FSMA 204 rule only for foods on the Food Traceability List?
Yes. Its additional records apply to listed foods and foods containing them, with exemptions. Other food businesses still keep records under 21 CFR Part 1 Subpart J.
How does UDI traceability differ from food traceability?
UDI identifies devices by a device identifier and production identifiers such as lot or serial number on the label and in the FDA's GUDID database. Food traceability records lots through supply-chain events.
Can spreadsheets handle traceability?
Only at very small scale. Errors grow with volume, rework and the number of customers.
Practical orientation, not legal advice. Rules differ by jurisdiction; your quality and compliance team decides what applies.
