One month, supplier costs are stable, but the next, a tariff announcement changes the economics of an entire product category.
Suddenly, inventory teams are faced with difficult decisions. Should you increase safety stock before costs rise? Are there alternative suppliers available? How much inventory should you buy now versus later, after the dust has settled a bit? What happens if demand slows after prices increase?
Netstock’s 2026 Tariff Impact Report found that 73% of SMBs have extended their inventory planning horizons in response to tariff uncertainty. Yet, our 2025 Supply Chain Benchmark Report showed 62% were still under-planning based on actual inventory outcomes.
The numbers tell us the challenge isn’t simply planning further ahead, but rather having the visibility, forecasting capabilities, and inventory intelligence needed to make accurate, confident decisions when conditions change.
For many businesses, tariffs are exposing planning weaknesses that have existed for years. This article explores what the latest tariff data reveals, why tariffs continue to expose inventory planning gaps, and the capabilities businesses need to respond with confidence when trade conditions shift.
Key Takeaways
- Tariffs are exposing inventory planning gaps that were easier to overlook in more stable cost environments, forcing businesses to make faster decisions around sourcing, inventory, and demand.
- SMBs are responding by becoming more proactive. Netstock’s latest tariff research found the number of businesses taking a “wait and see” approach dropped from 57% in 2025 to just 21% in 2026.
- Three planning areas have the greatest impact on operational continuity and cash flow during periods of tariff uncertainty: safety stock management, supplier performance visibility, and demand forecasting.
- The most effective planning tools help teams manage disruption by combining advanced forecasting, flexible inventory planning, supplier visibility, and scenario modeling capabilities.
- Data-driven decision-making is becoming a competitive advantage. Heavy analytics usage among SMBs more than doubled from 8% to 19%, reflecting a growing focus on forecasting, scenario planning, and faster decision-making during periods of uncertainty.
Why tariffs break traditional planning
Traditional planning tools were built for relatively stable cost environments. Tariffs disrupt that stability by introducing rapid changes to landed costs, sourcing opportunities, and demand patterns.
Over the past two years, shifting trade policies have made those changes more frequent and difficult to predict, creating a level of volatility many SMBs haven’t had to manage before.
Netstock’s 2026 Tariff Impact Report found that the number of SMBs taking a “wait and see” approach to tariff uncertainty fell from 57% to just 21% in a single year. Businesses that once had time to monitor conditions and adjust gradually are now being forced to make planning decisions much faster.
The challenge here isn’t necessarily the tariff itself, but the ripple effect that follows.
Higher landed costs put pressure on margins. Supplier relationships get complicated as businesses explore alternative sourcing options. Price increases can change customer buying patterns, making demand harder to predict.
Each of those ripples triggers new planning decisions around inventory levels, purchasing strategies, and cash flow.
Consider a distributor sourcing products from a supplier affected by new tariffs. A purchase order that made sense 60 days ago may now carry significantly higher landed costs. The team must decide whether to buy inventory ahead of other future increases, diversify suppliers, or revise forecasts to account for changing demand.
Without visibility into supplier risk, inventory exposure, and future demand signals, those decisions have to be split-second, when businesses are already feeling the consequences, or made on instinct rather than data. Neither option is strategic, which is why tariffs aren’t simply a sourcing challenge but a major planning challenge for SMBs without the right tools.
Reality check: How tariffs impact SMBs
Large enterprises often have advantages that help absorb tariff disruptions. They may have diversified supplier networks, dedicated trade compliance teams, and larger working capital reserves to cushion unexpected cost increases.
SMBs, on the other hand, seldom have similar resources. Our latest tariff data found that more than half of SMBs say tariffs are having a greater impact on their supply chains today than they were a year ago.
At the same time, 72% identified cost-related challenges as their biggest tariff-driven concern, highlighting the financial pressure many businesses continue to face.
The challenge becomes even more intense when supplier concentration enters the picture. Nearly 74% of SMBs identified China as their most impacted sourcing region. When a business relies heavily on a small number of suppliers or countries of origin, tariff changes can quickly limit sourcing flexibility and increase operational risk.
For SMBs, that means planning decisions carry more weight. A forecasting mistake, a supplier disruption, or an unexpected cost increase can have a much larger impact when fewer resources are available to absorb the fallout.
Many businesses are already responding to the pressure. The report found that 35% of SMBs changed suppliers during the past year due to tariffs, while 43% are actively pursuing supplier diversification strategies.
Access to better forecasting, supplier visibility, scenario planning, and inventory intelligence helps smaller teams evaluate trade-offs earlier and respond with greater confidence when conditions change.
Tariffs 101 for planners: How to safeguard processes and cash flow
Planners don’t need to become trade compliance experts to effectively respond to tariff uncertainty. They do, however, need visibility into the areas where tariffs have the biggest impact on inventory decisions, operational continuity, and cash flow.
Three pressure points deserve the most attention:
1. Safety stock
The latest tariff data shows many SMBs are increasing inventory buffers as part of their tariff response strategy. Safety stock helps protect service levels when supplier disruptions, sourcing changes, or cost increases create uncertainty. The challenge is finding the right balance. Too little inventory increases stock-out risk. Too much inventory ties up working capital and creates excess stock. Questions about safety stock become even more important when lead times and costs are changing simultaneously.
2. Supplier performance
Tariffs often expose risks that were already present within a supplier network. Lead time variability, country-of-origin exposure, reliability issues, and sourcing concentration all become more important when trade policies change. Strong supplier performance analysis helps planners identify potential disruptions earlier and evaluate alternatives before they affect inventory availability or customer service.
3. Demand forecasting
Tariff-related price increases don’t stop at procurement. The report found that 82% of SMBs have passed tariff-related cost increases on to customers, primarily through direct price increases. As prices change, customer demand can change too. Forecasts need to account for shifting buying patterns, changing order volumes, and the downstream effects of higher costs.
Putting it all together
Imagine a planner learning that a key supplier may be affected by a new tariff policy. Inventory levels need to be reviewed. Alternative suppliers may need to be evaluated. Forecasts may need adjustment if higher prices affect customer demand.
Looking at any one of those decisions in isolation creates risk. Looking at all three together gives teams a clearer picture of how to protect service levels, manage inventory exposure, and preserve cash flow as conditions change.
Where tariffs impact supply chain planning
A change in tariffs or trade policy can create a ripple effect across forecasting, sourcing, inventory, and fulfillment, forcing planners to evaluate multiple decisions at the same time.
Take a distributor importing a product line from a supplier impacted by a newly announced tariff. The immediate concern may be higher landed costs, but the planning implications extend much further.
- Demand planning: If costs increase and prices need to rise, customer demand may change as well. Teams need a demand planning solution that helps them evaluate how pricing adjustments could affect future sales volumes and inventory requirements.
- Supply planning: Existing suppliers may no longer represent the lowest-risk or most cost-effective option. Planners need visibility into supplier performance, lead times, and sourcing alternatives before disruptions occur.
- Inventory planning: Inventory buffers may need to be adjusted to account for potential supply interruptions or future cost increases. At the same time, carrying too much inventory can create cash flow challenges if demand slows unexpectedly. This is where inventory ordering automations can help planners respond more quickly to changing conditions, evaluate replenishment decisions, and maintain the right balance between service levels and working capital.
- Fulfillment and order execution: When supply constraints emerge, businesses may need to shift inventory between locations, adjust fulfillment priorities, or identify alternative ways to maintain service levels.
The challenge is that none of these decisions happens independently. A sourcing change can affect lead times. A pricing change can affect demand. A safety stock adjustment can affect cash flow.
That’s why what-if scenario modeling has become such an important capability for SMBs navigating tariff uncertainty. Rather than reacting to changing costs, planners can evaluate multiple outcomes in advance, understand potential trade-offs, and make decisions with greater confidence before disruptions occur.
Core features of tariff-aware supply chain planning tools
Tariffs are only one form of disruption, so rather than looking for AI tariff management software, businesses need to explore tools that support tariff-aware supply chain planning itself.
The reasoning is simple: if businesses can handle tariffs, which is just one type of disruption they may face when operating in global supply chains, they’re equipped to overcome broader challenges related to changing costs, supplier risk, demand shifts, and inventory uncertainty without slowing decision-making.
To succeed in volatile conditions, such as recent tariff shifts, many SMBs are actively adjusting pricing, diversifying suppliers, adapting safety stock levels, frontloading inventory purchases, and exploring scenario planning to navigate ongoing uncertainty.
Those strategies reveal an important truth: businesses need planning tools to quickly evaluate trade-offs and adapt when conditions change.
Looking across these mitigation strategies, certain planning capabilities stand out as especially important to consider when understanding how supply chain planning tools manage international tariffs.
- Advanced forecasting: Disruptions often create demand uncertainty. Price increases can affect purchasing behavior. Supplier constraints can influence product availability. Strong forecasting tools help planners identify changing demand patterns earlier, evaluate multiple outcomes, and make inventory decisions based on current conditions rather than outdated assumptions.
- Flexible inventory planning: The 2026 Tariff Impact Report found that 39% of SMBs are actively adjusting safety stock levels, while 31% are frontloading inventory purchases to reduce future tariff exposure. Those decisions require more than static replenishment rules. Planners need the flexibility to adjust inventory policies, evaluate risk, and understand the cash flow implications of carrying additional inventory.
- Supplier visibility and performance monitoring: Nearly four in ten SMBs are actively pursuing supplier diversification strategies. As supplier networks evolve, planners need visibility into lead times, reliability, sourcing risk, and supplier performance. Without that visibility, switching suppliers can create new operational risks while attempting to solve existing tariff-related ones.
- Scenario planning and decision support: Not every disruption unfolds the same way. A tariff increase, supplier delay, geopolitical event, or demand shift can each create different outcomes. Scenario planning helps teams model potential impacts before they happen, compare alternatives, and evaluate trade-offs across inventory, sourcing, service levels, and cash flow.
Let’s say a forecaster is evaluating whether to increase inventory ahead of a potential tariff change. Their decision will affect forecasting assumptions, supplier purchasing schedules, inventory investment, and customer service levels.
The strongest tariff-aware planning tools bring those variables together, allowing teams to evaluate options before committing capital and inventory to a particular course of action.
How businesses use AI to manage tariffs
Tariffs create a planning problem: more variables, more uncertainty, and more decisions to be made in less time. That’s where AI can help.
The strongest supply chain AI solutions don’t make tariff decisions for planners. They help teams identify patterns, evaluate trade-offs, and respond quickly when conditions change. In many cases, AI works alongside existing planning rules, making the comprehensive application as unique as the business itself.
| Planning challenge | Where AI helps | Where rules still matter |
| Demand changes after price increases | AI can identify shifts in demand patterns and help planners adjust forecasts as customer buying behavior changes. | Businesses still need inventory policies, service level targets, and replenishment rules that align with operational goals. |
| Inventory and planning anomalies | AI can surface unusual changes in inventory performance, forecast accuracy, or purchasing behavior that may require attention. | Inventory policies, ordering thresholds, and planning parameters still need to be defined and reviewed by planners. |
| Supplier and sourcing decisions | AI can help identify patterns in supplier performance, lead time variability, and inventory risk that may affect sourcing decisions. | Supplier qualification, contract management, and sourcing approvals remain human-led decisions. |
| Scenario evaluation | AI can help planners compare potential outcomes across inventory levels, forecasts, and supplier performance data more quickly. | Leadership teams still determine which trade-offs make the most sense for the business. |
The growing role of AI reflects a broader shift toward data-driven decision-making. The latest tariff research found that heavy analytics usage among SMBs more than doubled from 8% to 19%, while the number of businesses not using analytics at all fell to just 7%.
As tariff-related uncertainty has increased, more businesses are relying on data, analytics, and AI-supported insights to evaluate risks and make planning decisions faster.

Scenario modeling playbook: 5 tariff scenarios to run every quarter
Tariffs don’t always arrive with a lot of warning. That’s where scenario planning becomes valuable. The businesses that respond best aren’t scrambling to build a plan after a policy announcement. They’ve already evaluated potential outcomes and understand the trade-offs involved.
Running a few key scenarios each quarter helps teams identify risks earlier and prepare responses before costs, service levels, or cash flow are affected.
| Scenario | Inputs to evaluate | Business impact to measure | Primary decision owners |
| Sudden tariff increase | Landed costs, supplier lead times, inventory on hand, open purchase orders | Margin impact, inventory investment requirements, customer pricing implications | Supply Chain, Finance, Procurement |
| New country-specific duty | Country-of-origin exposure, supplier concentration, sourcing alternatives | Supplier risk, cost exposure, sourcing flexibility | Procurement, Supply Chain |
| Exemption removal | Product categories receiving exemptions, current sourcing strategy, future inventory needs | Margin pressure, replenishment costs, inventory policy changes | Finance, Supply Chain |
| Retaliatory tariffs | Export exposure, affected customer segments, demand forecasts | Demand changes, revenue risk, service levels | Sales, Finance, Demand Planning |
| Product reclassification or origin correction | Product classifications, supplier data, landed cost assumptions | Cost accuracy, compliance risk, profitability analysis | Trade Compliance, Finance, Procurement |
The value of scenario planning isn’t predicting exactly what will happen, but understanding how different outcomes affect inventory decisions before they become urgent.
For example, a sudden tariff increase may lead one team to increase safety stock while another recommends reducing inventory exposure to preserve cash flow. Scenario modeling gives planners a structured way to evaluate those trade-offs using data rather than assumptions or pure instincts.
When disruptions occur, the businesses that have already tested these scenarios can typically respond faster because the decision-making framework is already in place.
Implementation pitfalls and how to avoid them
Responding to tariffs is one challenge. Maintaining effective planning as costs, suppliers, and demand continue to change is another.
Many businesses recognize the need for better forecasting, supplier visibility, and scenario planning. The difficulty comes when those capabilities are introduced without the data, ownership, or processes needed to support them.
| Common pitfall | What happens | How to avoid it |
| Treating tariffs as a one-time event | Teams make a single adjustment and assume the problem has been solved, even as costs, suppliers, and demand continue to evolve. | Review planning assumptions regularly and incorporate scenario planning into quarterly planning cycles. |
| Poor supplier and origin data | Businesses struggle to understand where exposure exists, making sourcing decisions slower and more reactive. | Validate supplier, sourcing, and country-of-origin data regularly and establish clear ownership for maintaining it. |
| Disconnected planning and compliance efforts | Procurement, finance, planning, and compliance teams evaluate the same issue from different perspectives without a shared view of risk. | Create shared planning workflows and establish clear decision ownership across functions. |
| No closed-loop learning process | Teams react to disruptions but never evaluate whether forecasts, inventory decisions, or mitigation strategies were effective. | Regularly review outcomes, compare forecasts to actual results, and refine planning assumptions over time. |
One example is a business that increases safety stock in response to tariff uncertainty but never revisits the decision after conditions change. Inventory levels rise, working capital becomes constrained, and excess stock begins to accumulate. The original decision may have been reasonable, but without ongoing review, a short-term response becomes a long-term problem.
The businesses navigating disruption most effectively tend to treat planning as an ongoing process rather than a one-time exercise. Forecasts are updated, supplier performance is monitored, scenarios are revisited, and assumptions are challenged as new information becomes available.
Leveraging AI solutions for forecasting tariff risk scenarios
One of the biggest challenges with tariff planning is that future conditions rarely unfold exactly as expected.
A tariff increase may happen sooner than anticipated. A supplier may adjust pricing. Customer demand may respond differently than expected. Static planning assumptions struggle in these situations because they’re based on a single version of the future.
AI helps planners evaluate multiple possibilities. Rather than asking, “What will happen?” planning teams can ask more practical questions, such as:
- What happens if supplier costs increase by 10%?
- What happens if demand slows after the price adjustment we’re considering?
- What happens if lead times stretch even further while inventory levels are already elevated?
- What happens to the bottom line if a sourcing change reduces risk but increases costs?
These are the types of trade-offs businesses face when responding to disruption.
AI-powered forecasting tools help planners evaluate these scenarios more quickly by analyzing historical demand patterns, inventory performance, supplier trends, and forecast variability. These inputs come together to create a hypothetical “what-if” scenario.
Instead of manually building multiple models in spreadsheets, teams can compare potential outcomes and understand how different decisions may affect inventory levels, service performance, cash flow, and profitability.
Imagine a business evaluating whether to frontload inventory purchases ahead of a potential tariff increase.
Purchasing additional inventory may reduce future cost exposure, but it also increases inventory investment and working capital requirements. AI-supported scenario analysis helps planners understand those trade-offs before inventory is purchased and cash is committed.
The goal isn’t a perfect prediction. No planning tool can eliminate uncertainty. But with the right technology, businesses can be prepared for whatever tomorrow may bring.
No one knows what tomorrow will hold. Get started today
The last two years have made one thing clear: global tariff uncertainty isn’t going away anytime soon. Trade policies will likely continue to change. Costs will fluctuate. Supplier networks will evolve. New disruptions will emerge.
The businesses responding most effectively aren’t trying to predict every policy decision or market shift. They’re building planning processes that help them adapt when those changes happen. And it all starts with visibility.
The first step is understanding where inventory risk exists today and whether your current planning processes can see it clearly. AI-powered inventory management makes it easier. From there, businesses can strengthen forecasting, improve supplier visibility, build more resilient inventory strategies, and create a stronger foundation for whatever comes next.
