In plain English
Net 30 vs Net 60 is a cash-flow clause, not a courtesy. Net 30 means payment is due 30 days after invoice; Net 60 doubles the wait. For startups, the extra 30 days is runway. Diff every draft for silent edits, cap late fees, and consider early-pay discounts instead of eating Net 60 as a favor.
Not legal advice. Payment terms interact with credit, collections, and local late-interest rules. Escalate material or unusual money terms to counsel or your accountant.

What do Net 30 and Net 60 actually mean?
Net 30 means the invoice is due 30 days after the invoice date (or another stated trigger). Net 60 means 60 days. Variants include Net 15, Net 45, "2/10 Net 30," and "due on receipt." The phrase is only as good as the trigger: invoice date vs receipt vs end of month vs "acceptance of deliverables."
This usually lives in the MSA, the order form, or the SOW. If those conflict, order of precedence decides which clock you are on. Run it with fees and price-change rights: Startup MSA redline checklist.
Why does Net 30 vs Net 60 matter for cash flow?
Because you still pay payroll on Friday. An extra 30 days of receivables is not "enterprise professionalism." It is a working-capital loan you did not underwrite.
| You invoice | Terms | Cash in (if they pay on time) | What you funded |
|---|---|---|---|
| $20k on the 1st | Net 30 | ~the 31st | 30 days of delivery |
| $20k on the 1st | Net 60 | ~the 2nd of next month | 60 days of delivery |
| Same, paid 15 days late | Net 60 in practice | ~75 days | Your runway, quietly |
Sellers: Net 60 from slow AP can be a financing round you did not raise. Buyers: Net 60 can be fair when your own customers pay slowly, it is still a term, not a moral right. Match the clause to cash. Buyer-side pack: vendor contract review checklist.
Where do silent payment-term edits hide?
In the round nobody reads because "we already agreed price." Classic moves: MSA stays Net 30 while the order form says Net 60; the trigger becomes "after undisputed acceptance" with no clock; a portal cutoff adds two weeks; "end of month following invoice" quietly turns Net 30 into ~45–60; a clean copy with Track Changes off.
Silent Net 30 → Net 60 is the cousin of silent term-length changes. Diff against the last approved draft every round. On a founder/ops pass, this is a dedicated money look: How to review an MSA without a lawyer. Search the whole pack (MSA, SOW, order form, billing-guidelines URL) for "Net," "days," "invoice," and "acceptance."
How should you negotiate Net 60 when they insist?
You do not have to win the label to win the cash.
- Keep Net 30 in the MSA; grant Net 45/60 on a named order form so it does not infect every future SOW.
- Deposits or annual prepay so "Net 60" applies only to a remainder.
- Milestone billing instead of one invoice after all the pain.
- Early-pay discount so their AP looks like a hero and you still get money.
- Shorter first invoice as a credit-building ramp.
- Walk away or raise price if the extra 30 days is real cost of capital.
What you should not do: verbally agree Net 30, sign Net 60, and "remember to invoice early." Memory is not a payment term.
What about late fees, interest, and suspension?
Late fees exist so Net 30 does not become Net Whenever. Check the rate (annualized), whether there is a cap, notice before suspension if you are the customer, and a right to withhold the disputed slice. Unpaid fees are a common carve-out from a liability cap: fair for invoices, not a path to uncapped "all damages arising from late payment." Do not invent enforceability from a blog; rates are jurisdictional.
Should you offer or ask for early-pay discounts?
Early-pay (classic: 2/10 Net 30) is a clean trade: cheaper invoice for faster cash. As a seller, a small discount can beat a mystery 60-day wait. As a buyer, taking 2% for paying in ten days is often cheaper than a line of credit, run the math. Write the discount in the contract: percent, clock start, taxes, and what happens if they take the discount and still pay on day 40 (they owe the difference). Do not put it only in an email to AP.
What belongs on a payment-terms negotiation checklist?
- Net period matches the commercial handshake (30 vs 45 vs 60)
- Trigger is explicit (invoice date vs receipt vs acceptance)
- Acceptance, if used, has a deemed-accepted clock
- Same terms in MSA, SOW, and order form, or precedence is clear
- Portal / invoicing instructions do not silently add days
- Late interest/fees stated, reasonable, and paired with dispute/cure
- Suspension rights notice-based if you depend on the service
- Early-pay discount written, if that was the compromise
- Deposits / prepay / milestones if Net 60 is non-negotiable
- Diff vs last draft; Track Changes on; one canonical
