Operations: fulfilment, packaging & compliance
Net 30 means the full invoice amount is due thirty days after a starting date, with no discount for paying sooner. That is the whole definition. Everything that makes it hard is in the two words the definition leaves out: which starting date, and what actually happens on day thirty.
For an Amazon brand this is the first commercial term you will be asked to accept where the money moves later than the goods. On Amazon the sequence is comfortable and invisible: the customer pays Amazon at checkout, Amazon holds the funds, and a fortnight or so later a disbursement lands. You have never had to fund a customer. Net 30 means you now do.
What net 30 means in practice
You ship goods. You raise an invoice. Thirty days later the retailer pays the full amount. In between, your money is working for them.
That is not predatory, it is how trade credit has worked for a century, and it is the reason a store can stock four hundred brands without four hundred deposits. The retailer sells your product, collects cash at the till, and pays you out of proceeds. From their side it is a working capital model. From yours it is a loan you are making, at no interest, to a customer who is usually much larger than you.
You have probably already met a version of this inside Amazon itself, because business buyers on the marketplace can be extended terms on the same principle, as described in Amazon Business net terms. The difference is that there, Amazon carries the risk. Here, you do.
The number after "net" is only half the signal. Net 30 from a single-location shop that pays on a Friday run is a genuinely short cycle. Net 30 from a chain whose payment run is twice monthly can settle on day forty-two without anyone in their building considering it late. Ask how often they run payments, not just what the terms say.
Does the clock start at invoice date or receipt date?
This is the single most expensive detail in the whole arrangement, and it is usually one sentence in a vendor agreement nobody reads twice.
Net 30 from invoice date starts counting when you raise the document. If you invoice on the day the freight leaves, you are paid thirty days after shipment.
Net 30 from receipt date starts when their distribution centre counts the goods in. Between your dock and their receiving record sits transit, which for a cross-country truckload is four to six days, and a receiving backlog, which in a busy season is another three to five. Suddenly net 30 is net 40 measured from the day your cash left the building.
There is a third variant that appears at larger retailers: net 30 from receipt of a correct invoice. That wording puts the burden of correctness on you, and it resets the clock every time a document is rejected. An invoice that parks over a missing purchase order number and gets fixed on day twelve is now due on day forty-two, and the retailer is within the terms they wrote.
Negotiate the start date before you negotiate the number. Moving from receipt date to invoice date is often easier to win than moving from net 60 to net 30, and on a slow lane it is worth as much.
How does this compare with the Amazon payout cycle?
Amazon's rhythm is fixed and short, which is why it is so easy to stop noticing. A sale happens, the funds sit in an account, and a disbursement runs roughly every fortnight against a settlement period, minus a reserve that varies with account health. On average, cash for a sale reaches your bank a couple of weeks after the customer bought.
Net 30 on receipt date, from a retailer running a twice-monthly payment cycle, gets you paid five or six weeks after the truck leaves. So the cash lag roughly doubles or triples, and it does it on orders that are much larger than an individual Amazon sale.
There is one structural advantage on the wholesale side that is easy to miss. The Amazon cycle only pays you after a consumer chooses your product, which means you fund inventory sitting in a fulfilment centre for however long it takes to sell through. A wholesale order pays you on the whole case quantity whether or not the shop sells it that month. You wait longer per order, but you are not funding a warehouse of unsold units on the way there. The two cycles side by side are compared in Amazon payout versus net 30.
The cash gap on a first retail order, with dates
Numbers make this concrete. Take a made-up product: a waxed canvas dog leash that sells on Amazon for thirty-four dollars, wholesales at sixteen dollars, and costs you five dollars and twenty cents landed. A regional pet chain orders nine hundred units for their distribution centre on net 30 from receipt.
Start with the production cash, because this is the part sellers forget. Your factory wants thirty percent of the order value as a deposit, so put dates on it.
- March 3. Purchase order accepted for nine hundred units at sixteen dollars, a fourteen thousand four hundred dollar order.
- March 5. Factory deposit paid. Nine hundred units at five dollars twenty is four thousand six hundred and eighty dollars of goods cost; the deposit is one thousand four hundred and four dollars out of your account.
- April 14. Production complete, balance of three thousand two hundred and seventy-six dollars paid before release. Total cash out on goods so far: four thousand six hundred and eighty dollars.
- April 28. Goods land at your warehouse. Freight in, duty and handling take another six hundred dollars. Cash out: five thousand two hundred and eighty dollars.
- May 6. The order ships on a collect routing. You invoice the same day for fourteen thousand four hundred dollars.
- May 13. Their distribution centre receives and records the goods. The net 30 clock starts here, not on May 6.
- June 12. Due date.
- June 25. Payment actually lands, because their run is on the tenth and the twenty-fifth and the invoice missed the first one.
From first deposit on March 5 to cash in hand on June 25 is one hundred and twelve days. Your money was out of the business for nearly four months to earn a gross margin of nine thousand one hundred and twenty dollars. That is a good order. It is also an order you cannot place four of at once unless you have roughly twenty-one thousand dollars of working capital sitting idle, which almost no Amazon brand does, because the cash is all in FBA inventory.
This is the arithmetic that decides how fast you can grow a wholesale channel, and it is worked through more generally in Amazon seller cash flow.
Why a net 30 retailer still pays on day forty
Nobody in accounts payable decides to pay you late. Three mechanical things push the date out, and all of them are predictable enough to plan around.
The first is the payment run. Most mid-sized and large retailers pay on fixed dates rather than on due dates. An invoice due on the twelfth, in a company that pays on the fifteenth and the last day of the month, is paid on the fifteenth. That is three days, every time, forever.
The second is the match. Your invoice has to agree with their purchase order and their receiving record before it enters a payment run at all. A mismatch parks it silently, and the first you know is that the due date passed. An invoice fixed on day twenty may still catch the run; one fixed on day thirty-one waits a full cycle.
The third is simple document delay. An invoice emailed to your buyer rather than to accounts payable can sit unread for two weeks. Send it where it is processed, and send a statement monthly so anything that never arrived surfaces early.
Add those together and a genuine net 30 account paying in thirty-eight to forty-two days is normal rather than a problem. Build your forecast on forty and you will rarely be wrong.
What an early-payment discount really costs you
At some point a buyer will offer to pay faster in exchange for a discount, usually a two percent reduction for paying within ten days with the full amount due at thirty. It sounds small. It is not.
Put it on the invoice above. On fourteen thousand four hundred dollars, a two percent discount is two hundred and eighty-eight dollars, and it buys you the money twenty days earlier. Two hundred and eighty-eight dollars for twenty days of a fourteen thousand one hundred and twelve dollar advance is expensive money: annualised, you are paying somewhere north of thirty-five cents on the dollar per year for the privilege. No lender would charge you that.
So the discount is only worth offering in two situations. One, you genuinely cannot fund the next production run without the cash, and the alternative is a worse form of financing or a missed order. Two, you are using it deliberately as a negotiating chip to win terms elsewhere, such as a shorter clock or a smaller marketing allowance.
What matters more than the answer is that the discount is a price, not a favour, and it belongs in your wholesale number rather than in your goodwill. The way discounts and allowances stack into the real margin is covered in payment terms with retailers.
Credit checks and trade references
Terms are credit, so before a serious retailer grants them they will check you, and before you grant them you should check the retailer. Both directions are normal and neither is an insult.
When a chain onboards you as a vendor they may ask for bank details, a trade reference or two, and sometimes financial statements. If you are a young company with thin records, expect to start on shorter terms or a prepayment until a payment history exists.
Going the other way is the part Amazon sellers skip. Before you ship fourteen thousand dollars of goods to a company you met at a trade show, ask for two trade references from other suppliers and call them. The question is not whether the retailer is reputable, it is whether they pay on time, and other suppliers will tell you plainly. A commercial credit report is cheap and tells you whether other creditors are being paid late, which is the earliest warning you will get.
The signal that matters most is not size. Plenty of small independents pay in fourteen days because the owner writes the cheques. Plenty of well-known chains pay in fifty because the process says so.
When should you insist on payment before shipment?
There is no shame in it, and asking is far cheaper than writing off an order.
Ask for payment in advance, or a card on file, when it is a first order from an account you cannot reference; when the order is large enough that losing it would genuinely hurt; when the trade references come back vague or the credit report shows slow payment; or when the buyer resists giving you accounts payable details, which is a stranger signal than it sounds.
A workable middle position on a first order is half up front and the balance on net 30, or full prepayment on the first order with terms granted from the second. Most independents accept that without friction. A large chain will not, because their systems do not really do prepayment, and with a large chain the risk is usually slowness rather than default anyway.
Whatever you agree, write it on the purchase order acknowledgement and on the invoice, in words. Terms that live only in an email thread are terms you will lose an argument about.
If you have not got as far as a first purchase order, the earlier question is which retailers and distributors would carry your product at all. Paste your product link into WholesalePilot and the preview shows who would plausibly stock it, which is enough to know whether it is worth modelling the cash gap yet.
