Old B2B Invoices Could Decide $100 Billion in Tariff Refunds

The $100 billion U.S. tariff unwind isn’t just a legal exercise for enterprise firms; it’s exposing a crucial piece of B2B infrastructure.

More than 40 S&P 500 companies reported $9.6 billion in tariff refunds in the past quarter or so, with about $2.1 billion in cash already received. Those refunds initially flow to the importers of record that paid the duties to the government. But across B2B supply chains, importers frequently did not bear the entire cost themselves. Distributors and wholesalers passed tariffs downstream to manufacturers and other commercial customers through surcharges, duty line items and contractual price adjustments.

FedEx, for example, said that it will start disbursing its $800 million in refunds to shippers and consumers this month and that its website will enable customers to track their refunds.

That creates a second, potentially much larger reconciliation exercise: determining whether some of the money being returned to importers actually belongs farther down the supply chain. What initially looked like a government-to-importer refund process is becoming a private-sector B2B reconciliation exercise that could redistribute billions of dollars among distributors, manufacturers and other commercial buyers.

The most important evidence, then, may not be a customs filing. It may be an invoice that was paid a year ago and closed in the enterprise resource planning (ERP) software.

Tariff Refunds Turn the B2B Invoice Into a Claim on Cash

For CFOs, the implication is larger than recovering an unexpected check. Historical procurement records may contain assets and liabilities that have not yet been recognized. The companies with the cleanest contracts, invoice-level data and transaction lineage may be able to determine precisely who paid what, who recovered what and who is still owed money.

Tariffs frequently traveled through supply chains. Importers paid duties at the border, then attempted to recover some or all of the expense from distributors, manufacturers and other customers. Now that those duties are being returned, the same commercial paper trail that moved the cost downstream could determine whether some of the refund follows it.

An importer can remit a duty to Customs and then recover some or all of it from customers. A distributor may add a 15% tariff surcharge to a manufacturer’s invoice. A supplier may incorporate the cost into a temporary price adjustment. A contract may require customers to reimburse duties actually incurred.

Purchase orders, contracts, invoices, supplier emails and payment records can show whether a charge was a general price increase or an explicit pass-through of a particular tariff. That is where tariff recovery starts to look less like litigation and more like working-capital management.

A company may have millions of dollars of historical purchases that were booked, paid and forgotten. If those invoices contained identifiable tariff charges that have since been refunded upstream, some portion of that spending could now support a commercial recovery claim. In practical terms, a closed accounts-payable transaction can become the evidence for a new receivable.

Consider a manufacturer that purchased $50 million of components through an importer during the tariff period. If invoices carried a separately stated 10% tariff surcharge, the manufacturer does not need to construct an abstract economic model showing that higher tariffs probably affected pricing. It can potentially point to $5 million of identifiable payments.

The Real CFO Asset Is Actionable Data Lineage

The more consequential trend is what tariff recovery reveals about financial data itself. Companies have spent years investing in ERP systems, procurement software, accounts-payable automation and payment infrastructure largely to make transactions faster and easier to control. Tariff recovery demonstrates another source of value: historical financial records can become monetizable when external conditions change.

The implications expand beyond just tariff claw backs. Freight adjustments, commodity surcharges, energy costs, taxes, regulatory fees and other pass-through expenses move through complex supply chains. The more precisely those costs are tagged when money moves, the easier they become to audit, challenge, reverse or finance later. The humble invoice is, in effect, becoming a form of financial infrastructure.

“We’re moving from the era of ‘we have a lot of data — what do we do with it?’ to how do we leverage data and AI to drive outcomes?” FedEx Senior Vice President Jason Brenner told PYMNTS at the end of March.

Companies spent the tariff period figuring out how quickly they could transmit an unexpected cost through the supply chain. They may now discover that reversing that flow requires something harder: knowing precisely where every dollar went.
