Net-15 vs Net-30: The Core Difference
Net-15 and Net-30 are invoice payment deadlines. Net-15 means the client pays you within 15 days of receiving your invoice. Net-30 means they pay within 30 days. Both are "net" terms — payment is due in full, no discounts, no partial payments.
For a C2C contractor, this gap matters because you're not payroll. You don't get a weekly or bi-weekly deposit. You send an invoice, you wait, and during that waiting period you're running on fumes.
How Net-30 Drains Your Runway
Let's say you're a contractor at $80/hour, billing 40 hours a week. That's $3,200 a week or roughly $13,000 a month. On Net-30, you invoice on the first of the month and legally don't get paid until the 30th or 31st. But you still have to pay your business taxes, software subscriptions, and personal bills on the 15th.
If you're working on multiple contracts with staggered invoicing cycles, you can end up waiting for overlapping payments. One client on Net-30, another on Net-45 (less common but it happens), and suddenly you're 6-8 weeks into a contract waiting for your first paycheck while your accountant is asking about quarterly taxes.
Net-15 cuts that gap in half. You invoice the 1st, you're likely paid by the 15th. It doesn't eliminate cash flow pressure, but it creates predictability.
Which Terms Should You Negotiate For?
Net-15 is better for your cash flow. Always. But here's the operator's reality: most enterprise clients won't budge on Net-30. Large corporations have centralized accounts payable departments that process invoices in batches. They're not moving fast regardless of what the contract says.
Smaller vendors and startups sometimes go Net-15 or even Net-10. They move faster because they have fewer layers. If you're talking to a mid-market company or a startup, ask. If they balk, ask if they can pay on invoice submission instead of receipt — that shaves days off.
What you should never accept: payment tied to client deliverables or "end of project." That's not Net-30. That's indentured servitude. Lock in a calendar-based payment date.
The Hidden Cost of Extended Terms
Every week you wait for payment is a week you can't pursue your next contract or invest back into your business. If you're working multiple C2C gigs simultaneously (which many contractors do to smooth out gaps), you might carry simultaneous invoices from three different clients on different payment cycles. That's capital tied up.
Some contractors factor their invoices — they sell them to a third party at a discount to get cash upfront. That's an emergency lever, not a strategy. The discount eats 3-8% of your revenue just to survive to payday.
Structuring Your Cash Flow as a C2C
Build a buffer before you go full-time C2C. You need runway for at least two complete payment cycles. If you're Net-30 with a 15-day gap before invoicing starts, that's 45 days before money hits your account. Having 3 months of expenses saved covers mishaps: a client that stretches payment, a contract that ends early, a week between gigs.
Always invoice on time. Don't wait until the end of the month if your contract allows weekly invoicing. Every invoice you send is a timer that starts counting down to payment. The sooner you invoice, the sooner the clock runs out.
Document everything in your contract. Payment terms should be crystal clear: amount, due date, late fees (if you add them), and the invoice submission process. Vagueness costs you time chasing down overdue payments.
Why This Matters for Your Next Contract
When you're hunting for your next C2C role, payment terms are non-negotiable contract language. They sit next to rate and contract length as factors that determine whether a gig is actually profitable. A $100/hour contract on Net-45 with a 2-week ramp might be worse than an $85/hour contract on Net-15 that starts billing immediately.
If you're moving between contracts rapidly or stacking multiple vendors, you need visibility into your payment cycle before you sign. GiraffyReach's C2C market data includes payment-term intel from vendors, so you can benchmark whether Net-30 is the market standard for your role or if you have negotiating room.
FAQ
What does Net-15 mean for contractors?
Net-15 means the client has 15 calendar days from invoice submission (or receipt) to pay you in full. You send the invoice, they have until day 15 to transfer funds.
Can I negotiate Net-15 instead of Net-30?
Yes, but enterprise clients rarely change their standard terms. Smaller vendors are more flexible. Always ask; if they refuse, ask for payment on invoice submission instead of receipt to shave days off the clock.
What happens if a client doesn't pay by Net-30?
The invoice is technically overdue. You can charge late fees (if your contract specifies them) and legally escalate collection, but you still have a cash flow problem. Always negotiate clear terms upfront and document them in writing.
Is Net-30 standard for all C2C contracts?
Net-30 is typical for enterprise and mid-market clients. Smaller companies and startups may go Net-15 or Net-10. Your rate, contract type, and vendor size all factor into what's negotiable.
How much should I buffer for Net-30 payment delays?
Have 6-8 weeks of expenses saved before you go full-time C2C. That covers two payment cycles plus unexpected gaps between contracts. If you're working multiple vendors with overlapping invoices, that buffer buys you safety.
