Net 30 vs Net 15 vs Due on Receipt: Payment Terms Explained

Payment terms 101: what they mean and why they matter

Payment terms look simple: "Net 30" or "Due on Receipt." But the term you pick decides how fast cash comes in, how much chasing you'll do, and what the buyer assumes about the relationship.

Most small businesses default to Net 30 and never revisit it. The right term depends on who you're invoicing: a brand-new freelance client warrants different terms than a Fortune 500 corporation, and a retail customer different terms than a B2B vendor.

The four terms you'll see most

Due on Receipt

Payment due immediately — ideally before or at the time of delivery.

When to use it:

• One-off retail or e-commerce sales ($100–$500 range)
• New clients you haven't worked with before
• High-risk clients with a history of non-payment
• Deposits on project work (e.g., "50% deposit due on receipt")
• Upfront service fees

Pros:

• Cash in hand immediately (or within 1–2 days if digital)
• Zero collections workload — payment is built into the sale
• Zero credit risk

Cons:

• Creates friction with buyers who expect trade credit
• Smaller average deal size (buyers resist paying upfront for large projects)
• Can feel punitive to established relationships

Cash-flow impact: Positive. You're paid immediately.

Typical buyer reaction: "Sure" for small transactions; pushback for anything over $1,000.

Net 15

Payment due within 15 calendar days of invoice date.

When to use it:

• SMB clients (under 100 people) where you have a working relationship
• Freelance or contractor relationships (design, writing, development)
• Clients with a history of slow payment
• When your cash needs are urgent
• Monthly retainers or ongoing projects with predictable billing

Pros:

• Much faster cash flow than Net 30 — roughly half the payment window
• Feels less punitive than "Due on Receipt"
• Shows you're professional and organized
• Collections conversations happen sooner (you're flagging delays at day 16, not day 31)

Cons:

• Some buyers see 15 days as too aggressive; they may push back
• Requires more frequent collections follow-ups if they slip
• Smaller deals (usually $2,000–$10,000 range)

Cash-flow impact: Positive. You're financing 15 days instead of 30.

Typical buyer reaction: "OK, but can we do Net 30?" — negotiable.

Net 30

Payment due within 30 calendar days of invoice date.

When to use it:

• Default B2B term. Use this unless you have a reason not to
• Established clients and ongoing vendor relationships
• Mid-market and enterprise buyers (their AP cycles expect this)
• Project-based work ($5,000–$50,000 range)
• When you've already agreed to longer terms on a contract

Pros:

• Industry standard — most buyers' AP is built around this term
• Rarely gets negotiated or questioned
• Balances cash flow with buyer comfort
• Works for most freelance and small-business relationships

Cons:

• 30 days is a long float; if paid late, you're looking at 45–60 days
• Standard AP cycle means it gets looked at on day 28–30, not day 1
• Collections conversations don't start until day 31+

Cash-flow impact: Neutral. You're financing 30 days of working capital.

Typical buyer reaction: "Net 30 is standard" — accepted without question.

Net 60 / Net 90

Payment due within 60 or 90 calendar days.

When to use it:

• Large enterprise contracts (you often don't have a choice)
• When it's a condition of the contract you signed
• Government contracts (often mandate Net 30 or longer)
• Long-term partnerships where the buyer has leverage

Pros:

• Sometimes non-negotiable with enterprise buyers
• Shows you can accommodate their AP process
• Larger deal sizes ($50,000+)

Cons:

• You're financing 60–90 days of working capital — significant for small businesses
• If paid late (which is common), you're waiting 90–120 days
• Heavy collections workload in months 2 and 3
• Materially impacts your cash flow and requires more careful cash management

Cash-flow impact: Negative. You need working capital or a line of credit to float these invoices.

Typical buyer reaction: "Our AP only pays at 60 days" — often non-negotiable.

How payment terms affect your cash flow

Let's say you invoice for $10,000 on May 1 under different terms:

Due on Receipt: You're paid May 1 (or May 2 if electronic transfer). Payment delay: 1 day.

Net 15: Due date is May 16. You're likely paid May 17–20 (AP doesn't pay exactly on date, usually 1–3 days after). Payment delay: 16–19 days.

Net 30: Due date is May 31. Likely paid June 1–4. Payment delay: 31–34 days. (But if the buyer is 5 days late, you don't see the money until June 9.)

Net 60: Due date is June 30. Likely paid July 1–5. Payment delay: 61–64 days.

Over a year, if you invoice $100,000 monthly, the difference between Net 30 and Net 60 is $100,000 sitting in limbo. That's working capital you have to finance with a line of credit, which costs money.

Rules of thumb by client type

Fortune 500 / Large Enterprise

Terms they'll accept: Net 30, Net 60, or Net 90 (often their choice, not yours).

Typical pattern: Net 45 (de facto) — they pay the terms, but 5–15 days late.

Strategy:

• Negotiate the rate to account for the float. A Net 60 deal should be 3–5% more expensive than Net 30.
• Build invoicing into your contract upfront. Don't accept surprises after you've started work.
• Get a Net 30 upfront (deposit) to reduce float. Example: "50% Net 30 upfront, 50% Net 30 on completion."
• Track who approves invoices at the client. Don't address invoices generically to "Accounts Payable."

Collections: Don't follow up until day 45. Enterprise AP is slow by design, and early chasing teaches them to ignore you. At day 60, send one email asking for a payment date.

Mid-Market (50–500 people)

Terms they'll accept: Net 30 or Net 45 (negotiable).

Typical pattern: Net 35–40 (they accept Net 30 but pay a few days late).

Strategy:

• Propose Net 30 as your default. Most will accept it without pushback.
• If they ask for Net 45, ask them to split the difference: "Net 30, with an automatic 5-day grace period for processing" (i.e., de facto Net 35).
• Don't offer discounts for early payment — they don't take them.
• Get a PO number on every invoice. It's required for their AP system.

Collections: First follow-up at day 32–33. If they're a good customer, keep it warm and friendly. If it's a new client and they're late, be direct by day 40.

SMB / Freelance Clients (under 50 people)

Terms they'll accept: Net 15, Net 30, or Due on Receipt (varies widely).

Typical pattern: They'll ask for "Net 30 if possible," meaning they prefer it but don't expect it.

Strategy:

• Default to Net 15 if they're new or have slow-payment history.
• Use Net 30 for established, reliable clients.
• Offer "Due on Receipt" as a lower price. Example: "Net 30 is $5,000; Due on Receipt is $4,850." (This incentivizes immediate payment and covers the cost of float.)
• Get a clear verbal or email agreement on terms before you send the invoice. Don't surprise them with a term they didn't see coming.

Collections: First follow-up at day 17–18 for Net 15; day 31 for Net 30. SMB decision-makers are busy. A friendly reminder often works immediately.

Individuals / One-off Clients

Terms they'll accept: Due on Receipt (expected).

Typical pattern: They pay when they see the invoice.

Strategy:

• Default to "Due on Receipt" for all one-off work.
• If they ask for Net 30, it means they didn't budget for the expense. Ask for a 50% deposit upfront, with the balance due on receipt of the final work.
• Don't extend credit to individuals. The collections workload is outsized relative to the deal size.

Collections: One friendly reminder at day 3 if not paid; after that, it's not worth your time.

How to choose the right term for a new client

Ask yourself three questions:

1. How much is the invoice? Larger deals (over $10k) can bear longer terms. Smaller deals (under $1k) should be Due on Receipt or Net 15.

2. Do you have a relationship history? New clients should get shorter terms (Due on Receipt or Net 15) until you trust them. Established clients can get Net 30 or Net 45.

3. How tight is your cash? If you're cash-constrained, use shorter terms. If you have working capital, you can afford Net 30 or Net 45.

Once you've answered these, propose the term that benefits you most (tighter terms), then be prepared to move one step longer if the buyer pushes back.

Changing terms mid-relationship

If a buyer is consistently late, you can propose tighter terms for future invoices. Frame it as an operational change, not a penalty:

"Thanks for the great work on the project. Going forward, we'd like to streamline our invoicing to Net 15 to align with our internal processes. Does that work for you?"

They'll either accept (they probably will, because it's not a big ask) or ask for Net 30. Expect to land somewhere in the middle.

Never retroactively change terms or add late fees to past invoices. That's a relationship risk.
