Manufacturing finance leaders have been among the most impacted by the volatile tariff landscape. In manufacturing, tariffs are constantly reshaping sourcing, pricing, and supply chain strategies. Most companies have passed on the cost of import taxes to customers, as noted by a study released by the Kiel Institute for the World Economy, a German think tank. The US manufacturing sector has seen a 5.6% jump in manufacturing construction spending since the start of the tariffs, largely driven by industries with lower tariffs like computers/electronics and aerospace. Data centers and power generation & infrastructure are the real stories of US industrial growth, as per latest studies.Â
As business leaders scrambled to safeguard operations from unpredictable trade conditions, finance chiefs have essentially rewired operations that impact cost of goods sold, inventory management, reporting and compliance, tax planning, integrated business planning, forecasting, cost optimization, and risk management. Tariff-driven working capital swings called for tightening cash flow forecasting, re-negotiating vendor and customer payment terms, and optimizing inventory and sourcing.Â
In this blog, we explore the best practices followed by US manufacturing CFOs to manage tariff-driven working capital swings. Â
Why is working capital unpredictable in manufacturing?
Working capital volatility is high in manufacturing due to the unique nature of the industry. Operational costs are high because companies must continuously buy raw materials, often making large payments upfront, and tying up cash in long production cycles with revenue realized in weeks or months, or even longer. This creates significant cash flow gaps when demand or supply chains fluctuate.Â
Working capital is directly linked to operating cycle and, in turn, the revenue cycle (billing and payment collection). The following factors explain why manufacturing working capital is structurally more volatile than in most other sectors.Â
Key reasons for working capital pressure in manufacturingÂ
- Production and assembly timeÂ
Raw material is purchased, stored, and built into finished goods, keeping cash tied up in the work-in-progress before even a sale is made.Â
- Inventory build-upÂ
Manufacturers must maintain large buffer stock of raw materials and parts to ensure continuous production cycles, increasing Days Inventory Outstanding (DIO), average number of days a company holds its stock before selling it.Â
- Supply chain spikesÂ
Geopolitical shocks, material shortages, and supplier constraints can lead to unexpected price spikes forcing extra cash outlays to maintain production running.Â
- Demand fluctuationÂ
Sudden customer demand leads to increased spending on labor and materials, while sudden drops leave behind expensive, unsold inventory.Â
- Extended B2B payment termsÂ
Industrial and wholesale clients have extended credit terms and payment windows (60 to 90 days), straining short-term liquidity.Â
- High fixed overhead costsÂ
High fixed costs associated with plants and equipment means cash outflows continue even during production slowdown or lean period. Â
The structural working capital pressures described above are not new to manufacturing CFOs. What is new is the tariff layer sitting on top of them. Volatile import duties have amplified every one of these pressures simultaneously, driving up raw material costs, accelerating inventory build as a supply hedge, disrupting supplier payment terms, and compressing the planning windows that cash flow forecasting depends on. Â
Manufacturing CFO playbook for managing tariff-driven working capital challenges
For the finance teams supporting manufacturing, the restructuring of supply chains, sourcing relationships, and cost structures that this investment represents has fundamentally rewired the working capital dynamics they are managing, across inventory, payables, receivables, and cash flow forecasting simultaneously. The best practices below reflect how leading US manufacturing CFOs are managing the compounded pressure of structural working capital volatility and tariff-driven disruption at the same time.Â
Best practice 1: Build a tariff-aware cash flow forecasting model
The first and most foundational change that leading manufacturing CFOs have made is replacing static, backward-looking cash flow forecasts with dynamic, tariff-aware models that reflect the current cost structure of the business rather than its pre-tariff baseline.Â
A tariff-aware cash flow model connects input cost assumptions to sourcing decisions at the commodity and supplier level, allowing the finance team to model the working capital impact of a sourcing shift before it is executed rather than reconciling the cash flow consequences after the fact. It incorporates payment term assumptions by supplier geography, recognizing that nearshore and domestic suppliers frequently operate on different payment cycles than the offshore suppliers they are replacing. And it models inventory holding cost under different sourcing and safety stock scenarios, giving procurement and finance leadership the shared financial visibility to make inventory decisions that balance supply chain resilience against working capital efficiency.Â
The CFOs getting the most value from this model update are the ones who have built it on driver-based assumptions rather than historical extrapolation. When tariff rates change, a driver-based model updates the affected cost lines automatically. A model built on last year’s actuals requires a manual rebuild that takes weeks the finance team does not have.Â
Best practice 2: Renegotiate payment terms as a working capital lever
Payment terms are one of the most directly controllable working capital levers available to a manufacturing CFO, and tariff-driven supply chain restructuring has created a window to renegotiate them that may not stay open indefinitely.Â
On the payables side, the shift from offshore to nearshore and domestic suppliers creates an opportunity to negotiate payment terms that better reflect the shorter lead times and lower inventory buffers that nearshore sourcing enables. Suppliers who are competing for business in a reshoring environment are frequently willing to offer terms flexibility that established offshore relationships did not provide. Manufacturing CFOs who have used the sourcing transition as a trigger for structured payment term renegotiation have consistently improved days payable outstanding without damaging the supplier relationships that supply chain resilience depends on.Â
On the receivables side, tariff cost pass-through has created pricing conversations with customers that can be used to introduce or reinforce payment term discipline. Customers accepting price increases to cover tariff costs are, in many cases, also accepting tighter payment terms as part of the revised commercial relationship. Manufacturing CFOs who have linked price increase conversations to payment term discussions have improved days sales outstanding while maintaining the customer relationships that revenue recovery depends on.Â
Best practice 3: Optimize inventory strategy for working capital efficiency
Tariff uncertainty drove many manufacturers to build inventory buffers in 2024 and 2025 as a hedge against supply disruption and further cost increases. Those buffers improved supply chain resilience but they also tied up working capital at a cost that is increasingly difficult to justify as the immediate sourcing crisis has moderated and interest rates have kept the cost of carrying inventory elevated.Â
Leading manufacturing CFOs are now applying more sophisticated inventory optimization frameworks that distinguish between safety stock requirements driven by genuine supply risk and excess inventory that accumulated as a precautionary response to tariff uncertainty. The analytical foundation for this distinction requires item-level visibility into inventory carrying cost, stockout risk, lead time variability by supplier, and the working capital release available from targeted inventory reduction, an analysis that most manufacturers have not historically maintained with the granularity that the current environment demands.Â
The finance teams managing inventory working capital most effectively are the ones that have built a finance-procurement joint decision framework: shared visibility into inventory cost, shared accountability for working capital targets, and shared governance over the sourcing and stocking decisions that determine both.Â
Best practice 4: Strengthen AP and AR process discipline
Working capital management under tariff pressure is only as effective as the Accounts Payable (AP) and Accounts Receivable (AR) processes that execute it. A cash flow forecast that assumes 45-day customer payment terms delivers its working capital benefit only if the AR function is actually collecting on 45-day terms. A payment term negotiation that extends supplier terms to 60 days improves DPO only if the AP function is managing payment runs with the timing discipline to realize the full benefit.Â
The manufacturing CFOs who have seen the most durable working capital improvements from their tariff response strategies are the ones who invested in AP and AR process discipline alongside the strategic financial planning work. Structured collections workflows that enforce payment term compliance. Automated AP matching that eliminates the invoice processing delays that cause early payment regardless of negotiated terms. Real-time cash application that gives treasury accurate daily cash position data rather than estimates based on aged receivables. And management reporting that tracks DPO and DSO at the supplier and customer level rather than as blended organizational averages that mask the individual relationships that are most out of line with targets.Â
Best practice 5: Use scenario planning to stay ahead of the next change
The defining characteristic of the tariff environment is not the current tariff level. It is the pace and unpredictability of change. The manufacturing CFOs managing working capital most effectively are not the ones who have optimized for current conditions. They are the ones who have built the organizational resilience to meet what the next change means for their working capital position before it happens. Claus Aagaard, Group CFO of Mars Inc., says that organizational resilience should run through strategy, sourcing, governance, scenario planning, and digital infrastructure. Building resilience is key to responding strongly to rising uncertainty.Â
For manufacturing CFOs, this means maintaining live financial models for at least three tariff scenarios: current rates held, significant escalation, and partial rollback. It means having pre-agreed decision rules for each scenario such as which sourcing decisions would be triggered, which inventory positions would be adjusted, which payment terms would be renegotiated. And it means having the financial reporting infrastructure to monitor the leading indicators that signal which scenario is materializing, so the response can begin before the working capital impact is already in the bank statement.Â
Conclusion
Â
Tariff-driven working capital swings are not a temporary disruption that manufacturing finance teams can manage through until conditions normalize. The restructuring of US manufacturing supply chains, sourcing relationships, and cost structures that the current tariff environment has accelerated is a multi-year transition that will keep working capital dynamics in flux well into the years ahead. The manufacturing CFOs building the most resilient finance functions in response are the ones treating this not as a crisis to be managed but as a forcing function to build the forecasting accuracy, process discipline, and scenario planning capability that their finance functions should have had all along.Â
