The 6-hour finance problem
Technetium-99m has a half-life of 6.01 hours. By the time a unit dose leaves the cyclotron, is calibrated, packaged, and reaches a hospital nuclear medicine department, a meaningful percentage of its activity is already gone. For most ERP systems, this is invisible. Inventory is a count. A unit is a unit. Quantity at 6 a.m. equals quantity at noon until someone ships it.
For a radiopharmaceutical manufacturer, that gap is the operational and financial problem. As Archer's radiopharmaceuticals industry page notes, half-lives measured in hours mean every dose is a just-in-time manufacturing event, and every write-off is immediate. Activity decays continuously on a known mathematical curve. Cost of goods sold has to reflect the activity actually delivered. NRC 10 CFR Part 35 license conditions require activity tracking by lot and location at any point in time. And finance has to close the books on a product that, by definition, no longer exists in its original form.
NetSuite handles this, but only with deliberate configuration. Oracle NetSuite's Life Sciences ERP provides the lot traceability and audit trail foundation. Archer's work configures activity as a primary unit of measure, scheduled decay adjustment processes, batch costing tied to calibration time, and lot tracking mapped to NRC license conditions. The configuration has to be built for the physics of the product.
A dose calibrated at 25 mCi at 6 a.m. is 12.5 mCi by noon. For most ERP systems, this is invisible. For finance, it is the entire problem.
Why generic ERP fails radiopharmaceutical operators
Three failures recur.
Unit of measure
Activity is measured in millicuries or megabecquerels, not in each, kilograms, or liters. An ERP that cannot natively carry activity as a primary unit of measure forces the operations team into spreadsheet workarounds, which create the audit risk regulators look for first.
Time-sensitive valuation
Radiopharmaceutical inventory is continuously and predictably perishable on a known curve. An ERP that does not adjust inventory for decay overstates assets, distorts gross margin on every delivered dose, and produces a balance sheet auditors will challenge.
NRC and chain-of-custody documentation
10 CFR Part 20 and Part 35, along with state radiation control program requirements, require traceable activity by lot, by location, by time. An ERP that treats this as an afterthought layered on top of standard inventory will not survive a license renewal inspection.
How Archer configures NetSuite for radiopharmaceuticals
The foundation is the item record. For radiopharmaceutical SKUs, the primary unit of measure is the unit of activity. The container is secondary. Item records carry the isotope identifier and calibration timestamp as required fields. The isotope drives the decay constant used in scheduled adjustment processes.
A custom decay calculation script runs at fixed intervals, applies the standard exponential decay formula to every active lot, and adjusts activity on hand. Tc-99m, F-18, I-131, Lu-177, and Ga-68 each have their own decay constant. The math is standard. The implementation discipline is what separates a working configuration from a non-compliant one.
Costing uses a standard cost approach modified for activity yield. Unit cost is calculated against produced activity at calibration time. As activity decays in inventory, cost per remaining mCi rises, which is the financial reality. When a dose ships, COGS posts using the cost per mCi from the originating batch, applied to activity remaining at ship time. Decayed activity that never reaches a customer flows to a decay loss account.
Lot tracking is configured to NRC standards. Archer's Drug License App manages license authority references, authorized user attribution, and renewal cycles tied to the radioactive materials license. Bins map to physical locations a radiation safety officer would recognize on a facility diagram. Monthly reconciliation reports compare calculated decay-adjusted activity to physical survey measurements.
For radiopharmaceutical CDMOs serving multiple sponsors, 3PL Integration manages the specialized logistics partners and hospital delivery networks with real-time shipment confirmation and dose-level tracking.
