An E&O reserve that’s conservative by design
Fintra reserves slow-moving and obsolete inventory to net realizable value - taking the largest of an aging, specific-identification, or lower-of-cost-or-NRV reserve - and posts only the period delta.
Illustrative product view
Why inventory needs a reserve
Not all inventory is worth what you paid for it. Slow-moving and obsolete stock must be written down to net realizable value via a reserve - a contra-asset - so the balance sheet shows inventory at what you can actually recover: net value equals gross cost minus the reserve. Carrying dead stock at full cost overstates assets and defers a loss you’ll eventually take.
Net inventory value
net_value = gross_cost − reserve
The reserve is a contra-asset. Fintra takes the most conservative (largest) of three policies per item.
Three policies, most conservative wins
| Policy | How it computes | Typical use |
|---|---|---|
| Aging | Reserve % per age bucket × gross cost | Slow-moving stock by days since last movement |
| Specific-ID | 100% (or a set %) for flagged items | Known-obsolete SKUs |
| Lower-of-cost-or-NRV | max(0, unit cost − NRV per unit) × qty | Items worth less than they cost |
Post the delta, not the whole reserve
Each period, Fintra recomputes the required reserve and posts only the change - debiting obsolescence expense and crediting the inventory reserve for the delta. That true-up is idempotent, so running it twice doesn’t double the reserve. When you scrap reserved stock, it’s written off against the reserve first and only the unreserved portion is expensed.
- Recalculate posts the delta: DR Obsolescence Expense / CR Inventory Reserve.
- Preview mode computes the reserve without posting.
- The E&O report shows aging, specific, LCNRV, required reserve, and roll-forward.
- Scrap relieves reserved stock first, expensing only the excess.
Why auditors care
The E&O reserve is one of the first things an auditor tests, because it’s where inventory value is most easily overstated. A documented, policy-driven reserve that takes the most conservative view and posts a defensible roll-forward is exactly what they want to see.
Frequently asked questions
What is an excess and obsolete (E&O) inventory reserve?
An E&O reserve is a contra-asset that writes slow-moving and obsolete inventory down to net realizable value, so the balance sheet carries inventory at what’s recoverable - gross cost minus the reserve. It recognizes the loss on dead stock before it’s physically disposed of.
How does Fintra size the E&O reserve?
It computes three reserves per item - an aging-based reserve by age bucket, a specific-identification reserve for flagged-obsolete items, and a lower-of-cost-or-NRV reserve - and takes the most conservative (largest) of the three. That worst-case approach is what most manufacturers and auditors expect.
Does the reserve post the full amount each period?
No. Fintra posts only the period-over-period delta, debiting obsolescence expense and crediting the inventory reserve. The true-up is idempotent, so recalculating won’t double the reserve, and a preview mode lets you see the required reserve before posting anything.
What happens when reserved inventory is scrapped?
Scrapping writes the item off against the existing reserve first, so only the portion that wasn’t reserved hits expense. That prevents double-counting the loss and keeps the reserve roll-forward clean.
