Net 30 vs. Net 60 vs. Net 90: Impact on Manufacturer Cash Flow

Payment terms look like an administrative detail buried in a purchase order. They're not. For a manufacturer running a [nearshoring program](nearshoring program) — especially one stretching working capital across the US-Mexico border — the difference between Net 30, Net 60, and Net 90 is the difference between funding next quarter's production run from operating cash or scrambling for a credit line at 11% APR.

This comparison breaks down what each standard term actually costs, who wins and who loses on each side of the invoice, and how to think about payment terms strategically when you're scaling cross-border manufacturing.

What Net Payment Terms Actually Mean

"Net 30," "Net 60," and "Net 90" specify the number of calendar days a buyer has to pay an invoice in full after it's issued (or after goods are received, depending on contract language). The shorter the term, the faster the supplier gets paid — and the faster the buyer's cash leaves the bank.

In US domestic B2B manufacturing, Net 30 has long been the cultural default. In cross-border trade with Mexican producers, terms vary widely: established maquiladoras often demand Net 30 or even partial prepayment, while larger Tier-1 suppliers competing for nearshoring contracts may accept Net 60 or Net 90 to win the business.

Per a 2024 Atradius Payment Practices Barometer, the average B2B payment term across US industries sits around 38 days, but actual [days sales outstanding](days sales outstanding) (DSO) often runs 50+ days once late payments are factored in.

The Cash Flow Math: A Side-by-Side Comparison

Consider a US importer with $12M in annual COGS sourced from a Mexican supplier, ordering evenly throughout the year ($1M/month in invoices).

Metric	Net 30	Net 60	Net 90
Average payables outstanding	~$1.0M	~$2.0M	~$3.0M
Buyer cash freed vs. Net 30 baseline	$0	+$1.0M	+$2.0M
Supplier cash tied up	$1.0M	$2.0M	$3.0M
Supplier financing cost (@10% APR)	~$100K/yr	~$200K/yr	~$300K/yr
Typical price premium supplier demands	0%	1–2%	2–4%

The pattern is straightforward: extending terms moves working capital from the supplier's balance sheet to the buyer's. That capital isn't free — somebody is financing it. The question is who, at what rate, and whether the cost gets buried in unit pricing.

From the Buyer's Perspective

Longer terms improve days payable outstanding (DPO), reduce reliance on a revolver, and free cash for inventory buffers, tooling, or growth. For a CFO running a nearshoring transition, going from Net 30 to Net 60 on a $12M program effectively unlocks $1M in working capital — capital that might otherwise come from an asset-based loan at 8–12%. You can model this trade-off precisely with a supplier pay program ROI calculator before committing to a term restructure.

But the buyer pays for it indirectly. Suppliers price extended terms into their quotes. A 2% pricing premium on a $12M program is $240K/year — often more than the cost of bank financing the buyer would have used to pay faster.

From the Supplier's Perspective

For a Mexican manufacturer with a $5M annual contract on Net 90, roughly $1.25M is permanently locked in receivables. If their gross margin is 18%, the financing cost of carrying that receivable at peso-denominated lending rates (which often exceed 14% per Banco de México data) can consume 30–40% of contract margin.

This is why payment terms determine which suppliers a buyer can actually use. Small and mid-sized Mexican producers — exactly the kind of suppliers that staff nearshoring programs — often can't accept Net 60 or Net 90 without supply chain finance support. Push terms too hard and you eliminate half your supplier pool.

How Each Term Plays in Cross-Border Manufacturing

Net 30: The Default for Trust-Building

Net 30 is where most US-Mexico relationships start. It works well when:

• You're qualifying a new supplier and haven't established performance history
• The supplier is a smaller maquiladora without access to factoring
• Order volumes are small enough that a 30-day cash gap is manageable on both sides

The downside: Net 30 leaves the buyer's working capital fully exposed. If freight delays push delivery by two weeks, you're effectively paying before goods clear customs.

Net 60: The Negotiated Middle

Net 60 is the most common negotiated outcome on mid-sized cross-border contracts. It gives the buyer breathing room to receive, inspect, and (often) sell goods before payment is due. Suppliers can typically absorb 60-day cycles if their bank or factor offers receivables financing at reasonable rates.

This is where dynamic discounting and reverse factoring start to matter. A buyer offering Net 60 with an optional 2/10 early payment discount — or better, an embedded supply chain finance program — can capture margin while keeping the supplier's cash cycle short.

Net 90: The Strategic Lever (With Risk)

Net 90 is typically reserved for large buyers with strong credit and suppliers who have access to invoice financing or are large enough to self-fund. It's the most powerful working capital tool — and the most dangerous to supplier health if deployed without a financing wrapper.

The right way to deploy Net 90 in a nearshoring context is to pair it with a supplier pay program: the buyer holds 90-day terms on its books, but the supplier gets paid in 10–15 days through a third-party financer at a discount rate keyed to the buyer's credit. Both sides win.

We've covered the mechanics of this in our guide on extending terms without damaging supplier relationships and quantified the impact in a case study where a manufacturer freed $4.2M in cash by restructuring supplier terms.

The True Cost Comparison: It's Not Just APR

A naive comparison says "Net 90 saves the buyer money." A real comparison accounts for:

1. Supplier price premiums baked into unit costs for extended terms
2. Concentration risk — pushing too hard means losing suppliers
3. Quality and delivery risk — cash-strapped suppliers cut corners
4. FX exposure — longer terms on peso-invoiced contracts mean more time for currency moves to erode margin
5. Opportunity cost of capital freed up (what's the buyer's marginal return on that cash?)

A buyer earning 18% on reinvested working capital should aggressively extend terms. A buyer with idle cash should consider paying faster in exchange for a discount.

Choosing the Right Term for Your Program

There's no universal answer, but a workable framework:

• New suppliers, < $500K annual spend: Net 30, build performance history first
• Established suppliers, $500K–$5M spend: Net 45 or Net 60, optional dynamic discounting
• Strategic suppliers, > $5M spend: Net 60 or Net 90 with reverse factoring / supplier pay program
• Critical single-source suppliers: Whatever they need to stay financially healthy — supplier failure costs more than any DPO gain

For manufacturers moving production from China to Mexico, payment terms also become a competitive sourcing tool. Mexican suppliers competing for new nearshoring contracts will often accept longer terms than Chinese incumbents to win the business — but only if the buyer can credibly commit to volume and on-time payment.

Where Reshore Fits In

We at Reshore see payment term structure as one of the first questions to resolve when standing up a new Mexico-based supplier program. The wrong terms — too aggressive, or not aggressive enough — show up six months later as either a strained supplier on the verge of missing shipments, or a buyer's CFO asking why working capital ballooned.

Our platform qualifies Mexican manufacturers on financial dimensions alongside operational ones, so buyers know upfront which suppliers can accept Net 60 or Net 90 cleanly, which need a supplier pay program, and which should stay on Net 30 until they scale. That's how a nearshoring transition lands without the back-office cash crunch most companies don't see coming.

If you're evaluating moving production from China and want to understand how payment terms, tooling transfer, and supplier selection interact across the full reshoring journey, we can help.

Frequently Asked Questions

Q: What's the difference between Net 30 and 2/10 Net 30?

Net 30 means the full invoice is due 30 days after issue. "2/10 Net 30" adds an early payment discount: pay within 10 days and take 2% off the invoice. The annualized return on that 2% discount is roughly 36% — generally a much better use of cash than holding it for the remaining 20 days, assuming the buyer has the liquidity.

Q: Can I unilaterally change payment terms with my existing suppliers?

Legally, often yes — but operationally, it's how you lose suppliers. Unilateral term extensions damage relationships and can trigger price increases on the next contract cycle. The better approach is to pair any term extension with a financing option (reverse factoring, dynamic discounting) so the supplier isn't worse off.

Q: How do payment terms interact with USMCA and cross-border logistics?

USMCA doesn't dictate payment terms, but cross-border freight and customs timing affect when the "clock" starts. Some contracts trigger payment from invoice date, others from goods receipt or customs clearance. For Mexico-to-US shipments, the 5–10 day transit and customs window can effectively add a week to any payment term — clarify the trigger in writing.

Q: Are longer payment terms more common in Mexico than in China?

Generally, no — Chinese suppliers historically accepted longer terms because of subsidized export financing and intense competition. Mexican suppliers tend to start with shorter terms (Net 30 is common), but the gap is closing as nearshoring volume grows and more Mexican producers access supply chain finance.

Q: What's a reverse factoring program and how does it help with extended terms?

Reverse factoring (also called supply chain finance or a supplier pay program) is a buyer-led arrangement where a third-party financer pays the supplier early — within 10–15 days — at a discount rate based on the buyer's credit rating. The buyer still pays on the original terms (e.g., Net 90), but the supplier gets cash quickly and cheaply. It's the standard tool for deploying long terms without harming suppliers. Our FAQ on supplier pay program setup, costs, and compliance walks through the implementation details.

Q: Does Reshore help negotiate payment terms with Mexican suppliers?

Yes. As part of qualifying suppliers for our platform, we assess each manufacturer's financial capacity to accept various payment terms and flag where supply chain finance solutions are needed. This means buyers see realistic term expectations before they commit to a supplier rather than discovering term constraints mid-program.

Q: How much working capital can a typical manufacturer free up by extending terms from Net 30 to Net 60?

As a rough rule, extending terms by 30 days frees up working capital equal to roughly one month of COGS for that supplier program. For a $12M annual program, that's about $1M. Whether you should pursue it depends on the price premium suppliers charge and your marginal return on the freed cash.

Q: Do payment terms affect supplier quality and delivery performance?

Indirectly but significantly. Suppliers under cash flow stress cut corners — they defer maintenance, reduce QC headcount, prioritize customers who pay faster, and may even cut material costs. Healthy payment terms (or term-extension programs with financing wrappers) are part of supplier risk management, not just finance.
