Inventory valuation isn’t just a backend accounting choice—it’s a strategic lever that shapes how you price, forecast, and negotiate. If your costing method doesn’t reflect how your materials actually move, your margins are misleading. And misleading margins lead to bad decisions.
NetSuite gives you the flexibility to choose, but it’s up to you to align that choice with your operational reality. This section breaks down why that alignment matters more than most manufacturers realize.
Why Inventory Valuation Isn’t Just an Accounting Exercise
Inventory valuation is often treated like a compliance checkbox. You pick a method, set it in your ERP, and move on. But if you’re serious about financial clarity, that’s a mistake. Your valuation method directly affects your cost of goods sold (COGS), gross margins, and even how your team interprets performance. When those numbers don’t reflect reality, you’re flying blind—and that’s not just a finance problem. It’s a pricing problem. It’s a sourcing problem. It’s a leadership problem.
Let’s say you’re running a packaging operation that sources resin pellets. Prices have been climbing steadily. You’re using FIFO, so your COGS reflects older, cheaper inventory. Your margins look great on paper. But when your procurement team goes to reorder, they’re hit with a 20% price hike. Sales is still quoting based on the old margin. You win the deal, but you lose money. That’s not a spreadsheet error—that’s a valuation misalignment.
Now flip the scenario. You’re in industrial equipment, and steel prices are volatile. You switch to LIFO to reflect current costs. Your margins drop, but your pricing stays competitive and your tax burden shrinks. Your board sees lower profits and starts asking questions. But your cash flow is strong, and your sourcing strategy is defensible. That’s the power of choosing a method that matches your reality—even if it hurts your optics short-term.
Here’s the takeaway: inventory valuation isn’t passive. It’s active. It shapes how your business sees itself. And if you’re not aligning it with how your materials actually move—how your costs actually behave—you’re not just misreporting. You’re mismanaging. NetSuite gives you the tools to track, simulate, and segment costing methods. But the insight starts with you.
To make this clearer, here’s how different valuation methods can distort or clarify your financial picture depending on your cost environment:
| Cost Environment | Valuation Method | Impact on Margins | Impact on Pricing Accuracy | Strategic Risk |
|---|---|---|---|---|
| Rising input costs | FIFO | Overstated | Low | Underpricing deals |
| Volatile input costs | LIFO | Conservative | High | Misleading optics |
| Blended input costs | Average Costing | Smoothed | Medium | Hidden cost spikes |
Margins are only useful if they reflect reality. If your valuation method inflates or deflates them artificially, you’re making decisions on bad data. That’s why this isn’t just an accounting choice—it’s a strategic one.
Here’s another angle: valuation affects how your teams collaborate. If finance sees high margins but ops is struggling with rising costs, you get friction. If sales is quoting based on outdated COGS, you get churn. If leadership is forecasting based on smoothed averages, you miss inflection points. The method you choose sets the tone for cross-functional clarity—or confusion.
Sample scenario: a manufacturer of HVAC components used average costing across all SKUs. It worked fine when copper prices were stable. But when prices spiked, their blended cost masked the increase. Sales kept quoting based on the average, and they lost margin on every unit. Once they segmented costing by SKU—using FIFO for copper-heavy items—they regained visibility and adjusted pricing. NetSuite made the switch easy, but the insight came from recognizing the disconnect.
Here’s a second table to show how valuation methods affect different departments:
| Department | Valuation Misalignment Effect | Valuation Alignment Benefit |
|---|---|---|
| Finance | Misleading margins, poor forecasting | Accurate COGS, better cash planning |
| Sales | Underpricing, lost margin | Realistic quoting, stronger deals |
| Procurement | Budget mismatches, sourcing surprises | Cost visibility, smarter negotiations |
| Leadership | Misread performance, wrong strategy | Clear optics, confident decisions |
You don’t need to overhaul your entire ERP to fix this. You just need to audit your costing method, simulate the impact of switching, and align it with how your business actually operates. NetSuite gives you costing layers, simulation tools, and item-level flexibility. But the clarity starts with asking: are your margins telling the truth?
That’s the first step. Once you see valuation as a strategic lever—not just a compliance setting—you start making sharper decisions. You stop reacting to surprises and start anticipating them. And that’s when your ERP becomes a growth tool, not just a reporting system.
The Big Three Costing Methods—And What They Really Mean for You
Choosing between FIFO, LIFO, and average costing isn’t just about accounting—it’s about how your business actually runs. Each method tells a different story about your margins, your sourcing, and your pricing. If you’re using FIFO in a volatile market, you might be showing profits that don’t exist. If you’re using average costing in a blended-input environment, you might be missing cost spikes that are eating your margin. The method you choose should reflect how your materials move, how your costs behave, and how your teams make decisions.
FIFO (First-In, First-Out) works well when your input costs are stable or rising gradually. It assumes the oldest inventory is sold first, which means your COGS reflects older, often cheaper costs. That can make your margins look stronger, especially during inflation. But it also creates a disconnect between your reported profit and your actual replacement cost. If you’re sourcing aluminum for consumer appliances and prices have climbed 15% over the last quarter, FIFO will show healthy margins—until you reorder and realize your pricing hasn’t kept up. That’s where NetSuite’s costing layer visibility becomes critical.
LIFO (Last-In, First-Out) flips the logic. It assumes the newest inventory is sold first, so your COGS reflects current costs. This method is especially useful in volatile markets—think steel for heavy machinery or rare earth metals for electronics. LIFO helps you stay grounded in reality, even if it lowers your reported profit. One manufacturer producing industrial pumps used LIFO to track steel costs during a period of rapid fluctuation. Their margins dipped, but their pricing stayed aligned with actual costs, and their tax burden dropped. NetSuite handled the layer tracking automatically, giving their finance team confidence in the numbers.
Average costing smooths out the bumps. It’s ideal for manufacturers dealing with blended inputs—like chemical processors, food producers, or paint manufacturers. Every time you receive inventory, NetSuite recalculates the average cost, giving you a consistent COGS. That’s great for simplicity, but it can hide spikes. A food manufacturer sourcing spices from multiple regions saw a 40% jump in one input, but average costing masked the impact. They didn’t adjust pricing fast enough and lost margin. Once they split costing methods by SKU—using FIFO for volatile items—they regained control.
Here’s a table comparing how each method behaves under different cost conditions:
| Costing Method | Best Fit For | Margin Behavior | Pricing Accuracy | Complexity Level |
|---|---|---|---|---|
| FIFO | Stable or rising input costs | Inflated during inflation | Low | Moderate |
| LIFO | Volatile or declining input costs | Conservative | High | High |
| Average Costing | Blended or mixed input environments | Smoothed | Medium | Low |
And here’s how each method affects decision-making across departments:
| Method | Finance Impact | Sales Impact | Sourcing Impact |
|---|---|---|---|
| FIFO | Higher reported profit | Underpriced deals | Budget mismatch |
| LIFO | Lower taxable income | Realistic quoting | Better cost alignment |
| Average Costing | Consistent reporting | Delayed price updates | Blurred cost signals |
How NetSuite Supports Each Method—Without Breaking Your Ops
NetSuite doesn’t just let you choose a costing method—it helps you manage it across your entire inventory. Whether you’re using FIFO, LIFO, or average costing, NetSuite tracks item receipts, costing layers, and COGS in real time. That means you’re not just setting a rule—you’re building a system that reflects how your business actually works. And when your system reflects reality, your decisions get sharper.
For FIFO and LIFO, NetSuite automatically creates costing layers with each receipt. You can drill into those layers to see exactly which batch is hitting COGS, and when. That’s especially useful when you’re managing high-value inputs like copper, steel, or electronics components. One manufacturer producing smart meters used NetSuite’s FIFO tracking to isolate margin erosion on a specific SKU. They saw that older inventory was masking rising costs, and adjusted pricing accordingly. Without layer visibility, they would’ve missed it.
Average costing is even simpler. NetSuite recalculates the average cost every time you receive inventory. That’s ideal for manufacturers who don’t want to track individual batches—like those blending chemicals, mixing food ingredients, or assembling kits. A paint manufacturer using average costing saw consistent margins across SKUs, even as pigment prices fluctuated. But when one pigment spiked 60%, they used NetSuite’s costing simulation to test FIFO on that SKU. The result: clearer cost signals and better pricing decisions.
NetSuite also lets you segment costing methods by item. You don’t have to choose one method for everything. You can use FIFO for regulated SKUs, LIFO for volatile inputs, and average costing for blended items. That flexibility means you can match your costing method to your material flow—not the other way around. And with costing simulations, you can preview the impact of switching methods before you commit.
Sample Scenarios That Show Why This Matters
A manufacturer of HVAC components used FIFO across all SKUs. It worked fine when copper prices were stable. But when prices jumped 25%, their margins looked strong—until they had to reorder. Sales hadn’t adjusted pricing, and they lost margin on every unit. Once they switched to LIFO for copper-heavy SKUs, their COGS reflected real costs, and pricing caught up. NetSuite made the switch seamless, but the insight came from seeing the disconnect.
A chemical processor blending agricultural inputs used average costing. It simplified reporting and kept things clean. But when one input spiked due to supply chain issues, the average masked the increase. They didn’t adjust pricing fast enough and saw margin erosion. By segmenting costing methods—using FIFO for volatile inputs—they regained visibility. NetSuite’s costing groups let them apply different methods by SKU without disrupting workflows.
An electronics manufacturer sourcing rare earth metals used LIFO to reflect current costs. Their margins dipped, but their pricing stayed competitive and their tax burden dropped. The board questioned the lower profits, but NetSuite’s costing reports clarified the story. They showed how LIFO aligned with actual sourcing costs, and how it protected cash flow. That clarity helped leadership stay confident in the numbers.
A food manufacturer using average costing across all SKUs noticed that their spice-heavy products were losing margin. They dug into NetSuite’s costing reports and saw that one input had spiked 40%, but the average masked it. They switched to FIFO for those SKUs and used NetSuite’s simulation tools to preview the impact. The result: better pricing, clearer margins, and stronger sourcing decisions.
How to Choose the Right Method for Your Business
Choosing the right costing method starts with understanding your material flow. Are your inputs stable, volatile, or blended? Do you need precision or simplicity? Are you optimizing for margin clarity, pricing accuracy, or tax exposure? Once you answer those questions, the right method becomes obvious. NetSuite gives you the flexibility to apply different methods by item, so you’re not locked into one approach.
If your inputs are stable and predictable—like packaging materials or standard components—FIFO might be your best fit. It keeps margins high and reporting clean. But if your inputs are volatile—like metals, electronics, or imported goods—LIFO gives you a more realistic view of costs. And if you’re blending inputs—like chemicals, food, or paint—average costing simplifies the math without losing too much clarity.
NetSuite’s costing simulation tools let you preview the impact of switching methods. You can see how your margins, COGS, and inventory values shift—without touching live data. That means you can test before you commit. And with item-level costing, you can apply different methods to different SKUs, giving you precision without complexity.
Here’s a quick decision matrix to help you choose:
| Input Type | Cost Behavior | Recommended Method | Why It Works |
|---|---|---|---|
| Standard components | Stable | FIFO | Clean margins, predictable flow |
| Metals/electronics | Volatile | LIFO | Realistic costs, tax efficiency |
| Blended inputs | Mixed | Average Costing | Simplicity, consistent reporting |

Top 5 FAQs on Inventory Valuation in NetSuite
How do I change the costing method for a specific item in NetSuite? You can change the costing method by editing the item record directly. NetSuite allows you to assign FIFO, LIFO, or average costing at the item level, so you can tailor valuation to how each SKU behaves. Just be sure to simulate the impact first—changing methods affects future transactions and reporting.
Can I use different costing methods across my inventory? Yes. NetSuite supports mixed costing strategies. You can apply different methods to different items using item categories or costing groups. This is especially useful if you’re managing a diverse inventory with varying cost behaviors.
Will switching costing methods affect my historical data? No. Historical data remains intact. When you switch methods, NetSuite applies the new logic to future transactions only. That said, it’s smart to run costing simulations before switching so you understand how your margins and reports will change.
How does NetSuite handle costing for assemblies and kits? NetSuite rolls up component costs based on the costing method assigned to each item. If you’re using average costing, it blends the inputs. If you’re using FIFO or LIFO, it pulls from the relevant layers. You can drill into the cost breakdown for each assembly to see how it was calculated.
What’s the best way to preview the impact of switching costing methods? Use NetSuite’s costing simulation tools. They let you test different methods without affecting live data. You’ll see how your COGS, margins, and inventory values shift—so you can make informed decisions before committing.
Summary
Inventory valuation isn’t just a backend setting—it’s a lens through which your entire business sees cost, margin, and performance. When that lens is misaligned, you’re not just misreporting—you’re misjudging. NetSuite gives you the flexibility to choose and segment costing methods, but the clarity starts with understanding your material flow and cost behavior.
If you’re using FIFO in a volatile market, you might be overstating margins and underpricing deals. If you’re using average costing across blended inputs, you might be missing cost spikes that are quietly eroding profit. And if you’re using LIFO without explaining it to stakeholders, you might be showing lower profits that don’t reflect your actual strength. The method matters—and so does the story it tells.
You don’t need to overhaul your ERP or hire a consultant to fix this. You just need to audit your current setup, simulate the impact of switching, and align your costing method with how your business actually runs. NetSuite gives you the tools. This guide gives you the clarity. Now it’s your move.
