Short answer
Cycle counting is an inventory auditing procedure in which a small portion of inventory is counted on a regular basis instead of counting everything at once. A physical inventory count is the full count, which Sage Intacct’s help documentation describes as usually yearly and requiring operations to shut down. The regulations covered below ask for a physical inventory; none of the sources cited here says a cycle count replaces one.
Definition and scope
Sage Intacct’s help page on cycle counts defines cycle counting as “an inventory auditing procedure in which a small amount of inventory is regularly counted in the warehouse,” and says it helps maintain inventory accuracy throughout the year without interrupting daily operations. The North Carolina Office of the State Controller describes its cycle counting process as one used to assess stock levels within an inventory organization and correct any discrepancies.
In both descriptions the count is compared with the quantity the system expects, and the difference is resolved. That comparison is what separates counting from simply looking at a shelf: the output is a list of discrepancies and an adjustment, not a total.
A physical inventory count (also called a physical inventory or wall-to-wall count) is the contrasting case: a full count of the items, rather than a rotating subset. For the supply side of labs and clinics, see medical supply logistics for how supplies reach a site and kanban inventory for a replenishment method that sits alongside counting.
How a cycle count runs in practice
Sage Intacct: a rolling partial count
The Intacct documentation says users can apply any of the commonly known cycle counting techniques, and gives as an example a focus on items of higher value, higher movement volume, or those critical to business processes. Its workflow ends with reconciling the count results and adjusting inventory, so that quantities match between expected and actual on-hand.
North Carolina OSC quick reference INV-44: a scheduled, approved count
The state’s INV-44 guide for its ERP shows one concrete configuration. Its example assigns ABC classes a number of counts per year: A items 200, B items 150, C items 100. That is an example setting in one state system, not a standard or a recommendation. The guide also lists optional tolerance fields (adjustment value tolerance, quantity variance percentage, hit and miss percentage) without giving values, and an approver can approve, reject, or request a recount.
Cycle count vs physical inventory
| Question | Cycle count | Physical inventory count |
|---|---|---|
| How much is counted at a time | A small amount of inventory, regularly (Sage Intacct) | The full inventory (Sage Intacct) |
| How often | Regularly, on a schedule the organization sets; INV-44 example: A items 200 counts per year | Usually yearly (Sage Intacct); at least once every two years for federally funded property under 2 CFR 200.313(d) |
| Effect on daily operations | Does not interrupt them (Sage Intacct) | Requires shutting down operations (Sage Intacct) |
| Ends with | Reconcile and adjust inventory; approver may approve, reject or request a recount (Sage Intacct, INV-44) | Results reconciled with records (2 CFR 200.313(d)); book amount adjusted to the actual inventory (IRS Publication 538) |
Where it matters for labs and clinics
Two public rules show why the distinction matters. Neither mentions cycle counting.
- Federal award equipment. 2 CFR 200.313(d) requires property records that include a description and a serial number or other identification number, a physical inventory of the property, reconciliation of the results with the property records at least once every two years, and a control system to safeguard against loss, damage, or theft. Where equipment bought with federal funds sits in a lab, the rule calls for a physical inventory. Loss patterns are covered in inventory shrinkage.
- Taxable inventory. IRS Publication 538 says goods on hand can be figured by a perpetual or book inventory if kept under sound accounting practices, that a physical inventory must be taken at reasonable intervals, and that the book amount must be adjusted to agree with the actual inventory.
A cycle count produces the same kind of evidence, counted quantity against recorded quantity, but a rolling subset is not by itself the full count those texts describe. Whether a given organization’s schedule of cycle counts satisfies an auditor or funder is a question for that organization’s finance or compliance office, not something the cited sources settle.
A cycle count also relates to stock-out risk. The stockout guide explains what a shortfall of a needed item means; a count that corrects a wrong on-hand quantity is one way a recorded balance gets closer to the shelf. Software that holds the balances is compared in laboratory inventory management software.
Common misunderstandings
- “Cycle counting is just counting more often.” In the Intacct and INV-44 descriptions it is a partial, scheduled count with a reconcile-and-adjust step and, in INV-44, an approval step.
- “A cycle count replaces the annual count.” None of 2 CFR 200.313(d), IRS Publication 538, the Sage Intacct help page or the North Carolina guide says so.
- “The ABC counts per year are the standard.” The 200, 150 and 100 figures are one state ERP example.
FAQ
What is the difference between cycle counting and a physical inventory?
Cycle counting regularly counts a small amount of inventory without interrupting operations; a physical inventory counts everything, usually yearly, and requires shutting operations down (Sage Intacct).
What is a physical inventory count?
A full count of the items on hand, reconciled with the records. 2 CFR 200.313(d) requires one for federally funded property at least once every two years, and IRS Publication 538 requires one at reasonable intervals for inventories.
Which items are counted first in a cycle count?
That is the organization’s choice. Intacct gives items of higher value, higher movement volume, or critical to business processes as examples.
