Summary: Why is AP becoming a supply chain resilience issue for manufacturers? This blog explores how tariff volatility, reshoring, and shifting supplier contracts are putting new pressure on finance teams to manage invoices, approvals, payments, and cash exposure with greater speed and control. Learn how a connected AP automation platform helps manufacturers catch pricing changes sooner, protect supplier relationships, improve forecasting, and stay resilient as trade conditions keep moving.
The average effective tariff rate on U.S. imports has climbed to 9.6%, up from just 2.3% at the start of 2025, and it's still moving. Manufacturing finance teams are locking in supplier contracts for Q4 and heading into 2027 right in the middle of that shift, and this year's negotiations look nothing like they did a few years ago. Tariff policy has changed fast enough to reshape sourcing decisions mid-quarter, and that swing, tracked by the Tax Policy Center, is still working its way through supplier pricing and contract terms today.
Add reshoring to the mix and the picture gets more complicated. Manufacturers are trying to diversify suppliers, bring more production stateside, and renegotiate terms, often all at once. None of that happens in isolation. Every one of those moves runs through the same department that tends to get the least attention when supply chain strategy comes up, and that's accounts payable.
Here's the part worth sitting with. Sourcing strategy, reshoring plans, and tariff mitigation all sound like procurement and operations problems. But every one of them eventually turns into an invoice, an approval, and a payment. If AP can't keep pace with how fast those decisions are moving, resilience stalls out right where it matters most.
A few years ago, "supply chain resilience" mostly meant having backup suppliers and healthy inventory buffers. In 2026, it means something closer to constant recalibration. The Association for Supply Chain Management now names trade policy as one of the most influential forces reshaping supply chains this year, and that influence goes well past customs paperwork. It touches sourcing, lead times, and long-term contract structure.
You can see this play out at scale with major manufacturers. Ford and General Motors have both been navigating tariff refund uncertainty this year, with Ford projecting roughly $1.3 billion in refunds for levies later invalidated and GM expecting around $500 million. Both companies still face significant duty costs even with those refunds pending, and neither has a clear timeline for when the money actually arrives. Costs move, refunds sit in limbo, and contracts written even six months ago may already be out of step with reality.
Smaller and mid-sized manufacturers feel this even harder. They don't have the hedging tools or the balance sheet cushion that a Ford or GM can lean on, so a single mispriced contract or a delayed vendor payment carries a lot more weight for that relationship. When margins are already compressed by tariff costs, the last thing anyone needs is an AP bottleneck adding friction on top of it.
This is exactly why August matters so much this year. Contracts signed now will carry pricing assumptions into 2027, and those assumptions need to hold up against a trade environment that's still moving. Locking in terms without a clear read on cost exposure, or without an AP process fast enough to catch pricing changes as they hit, means renegotiating from a weaker position later.
Manufacturing CFOs already know this. No industry is feeling tariffs more than manufacturing right now, and more than half of manufacturers point to workforce impacts as their biggest strategic response to that pressure. AP automation, forecasting, and management reporting all rank as top priorities for manufacturing CFOs heading into next year, which says a lot about where finance leaders think the real leverage sits, according to a recent survey of more than 200 senior finance leaders.
Reshoring adds its own layer of complexity on top of that. Lower corporate tax rates and regulatory reform are pulling more production back to U.S. soil, and Deloitte's latest manufacturing outlook frames that as genuinely good news for long-term supply chain stability. It also means new entities, new supplier relationships, and new approval structures for finance teams to stand up fast. Growing that quickly without a consistent AP process is how invoices start slipping through the cracks.
Working capital pressure sits underneath all of it. Finance leaders are now treating cash forecasting almost as urgently as fraud prevention, with 80% ranking it a top priority in a recent Visa and U.S. Bank survey.
Yet checks still make up 12% of commercial payment volume at more than 60% of companies, a habit that quietly drags on visibility and float. When you're trying to manage cash carefully enough to absorb tariff swings, that kind of drag adds up fast.
None of this stays abstract for long. A supplier is waiting on payment while a plant manager is waiting on the materials that payment unlocks. A controller is juggling three different sets of payment terms across entities that didn't exist a year ago. Somewhere in between, a finance team is trying to model next quarter's landed costs while last quarter's invoices are still sitting in someone's inbox.
A few patterns keep repeating across manufacturers dealing with this right now.
Each of these on its own is manageable. Stacked together during a stretch of tariff uncertainty and active reshoring, they turn AP into a genuine supply chain risk rather than a back-office inconvenience. onPhase covered this exact dynamic in more depth in a recent look at what multi-entity growth does to AP as manufacturers reshore, and the pattern holds up across nearly every manufacturer navigating expansion right now.
This part of finance doesn't need a total overhaul to hold up under pressure. It needs an AP process built to absorb volatility instead of getting knocked over by it, and manufacturers who've made that shift are already seeing it pay off.
Start with capture and matching. When invoices come in through intelligent capture instead of manual entry, exceptions get flagged automatically rather than discovered three weeks later during month-end close. Two-way, three-way, or four-way matching catches pricing discrepancies against purchase orders in real time, which matters more than ever when tariff-driven cost swings are showing up mid-cycle.
Approval routing matters just as much. Rules-based workflows route invoices to the right approver automatically, even across multiple entities with different sign-off structures. A payment that clears on time keeps a supplier confident.
One that doesn't has them chasing the finance team for the third week in a row. Faster, more consistent approvals protect the relationships that keep materials moving from the loading dock to the production floor.
Visibility ties it all together. When finance leaders can see liabilities, exceptions, and cash commitments in one place instead of piecing them together from spreadsheets and email threads, forecasting gets a lot more realistic. That kind of visibility is exactly what lets a CFO walk into a Q4 contract negotiation with real numbers instead of estimates built on outdated assumptions.
That same visibility extends past invoices. When contracts, purchase orders, and supplier communications live in one connected document management system instead of scattered folders and inboxes, finance teams can pull up the full paper trail behind any payment or price change in seconds, which matters when a refund claim or a tariff dispute lands on someone's desk.
Workflow automation isn't limited to AP approvals either. The same rules-based routing that speeds up invoice sign-off can extend to budget approvals, contract renewals, and other financial processes that used to bottleneck around finance.
Payments deserve a mention here too. A lot of manufacturers are still paying suppliers the way they did a decade ago, leaning heavily on checks even though that method offers the least flexibility and the weakest visibility of any payment type. Shifting more of that volume to ACH or virtual card doesn't just speed things up. It gives finance teams more control over payment timing, which becomes a real advantage when cash needs to go further while trade policy stays this unpredictable.
Tariff volatility isn't going away, and reshoring won't get simpler on its own. But finance teams with the right AP process can respond to change without losing control of cash or supplier trust in the process. That's resilience at the AP level, and it's the piece too many supply chain strategies still overlook.
Tariffs aren't settling down anytime soon, and reshoring is only going to add more complexity before it adds stability. Manufacturers who treat AP as a strategic lever, not just a back-office function, are the ones who'll negotiate Q4 and 2027 contracts from a position of strength instead of playing catch-up.
onPhase was built to close exactly that gap. Our platform connects AP, payments, document management, and workflow automation, giving manufacturers the approval speed, visibility, and consistency to keep vendor relationships intact and cash flow predictable, even when tariff policy or reshoring plans shift the ground under them.

Manufacturing AP Automation FAQs
What does supply chain resilience mean for manufacturers right now? It means being able to absorb tariff shifts, supplier changes, and reshoring moves without losing control of cash or vendor relationships. That kind of resilience depends on how fast a company's internal processes, especially finance, can adapt when conditions change.
Why is AP getting more attention as a supply chain risk? Tariff volatility and reshoring both create more contract changes, more pricing exceptions, and more new supplier relationships than usual. Every one of those changes eventually becomes an invoice, and a slow AP process turns that volume into payment delays that strain supplier trust.
How does AP automation help manufacturers manage tariff-driven cost changes? Automated capture and matching flag pricing discrepancies against purchase orders as invoices come in, instead of surfacing them weeks later during close. That gives finance teams faster visibility into cost changes and more time to react before they affect supplier payments.
Why does the timing of Q4 and 2027 supplier contracts matter so much this year? Contracts signed this quarter carry pricing assumptions into next year, and those assumptions have to hold up against a trade environment that's still shifting. Negotiating without a clear, current read on cost exposure means renegotiating from a weaker position later.
What's the difference between AP automation and a broader financial operations platform? AP automation typically focuses on invoice capture, matching, and approvals. A financial operations platform extends that further, connecting AP, payments, and document management so finance teams get one consistent view of liabilities, cash, and vendor activity instead of piecing it together across systems.
