Two suppliers submitted the exact same figures for the same item. One requested payment upfront, the other was willing to wait thirty days after receiving the goods. On paper, the prices were even. In practice, they were not: one uses your money for a month, the other uses their own money. That difference is real, it just never appears as a separate line item in the offer.
Payment terms are the only part of a deal that changes cost without changing price. Therefore, it deserves to be decided upfront, not negotiated later when offers have already come in and you have lost your bargaining power. This article discusses five commonly used payment structures, the actual risks you bear in each, and how to write them into a request for quotation (RFQ) so that incoming offers can still be compared equally.
Payment terms are actually part of the price
When a supplier agrees to receive payment thirty days after goods are received, they are lending you working capital for thirty days. That money has to come from somewhere: their company's cash, a bank facility, or payments from their other customers. All of these have costs, and those costs will show up somewhere, usually in the unit price.
This is why the question "what is the price" is incomplete without "under what payment terms". The same supplier often has two different figures for the same item, and both are reasonable. What is unreasonable is comparing one supplier's long-term payment figure with another supplier's upfront payment figure, and then concluding that the latter is cheaper. The same incorrect pattern also occurs with shipping costs and taxes, and has been discussed separately in landed cost: why the cheapest price often becomes the most expensive.
Five commonly used structures
Almost all procurement agreements fall into one of the following five forms, or a combination thereof.
Full payment in advance. The entire value is paid before goods are shipped. This usually results in the best price and the most enthusiastic supplier, but all risk transfers to you: if the goods do not arrive or are not as specified, your bargaining position is zero because the money has already moved.
Partial advance payment, the rest upon delivery. The most common form for both stock and custom-ordered goods. The advance payment covers the supplier's material costs, while the remainder remains an incentive for them to complete the job correctly. The amount is negotiable and highly dependent on whether the item is standard or custom-made.
Payment after goods are received. Payment is due a certain number of days after the complete goods are received or after the invoice is issued. Note the difference: calculated from the shipping date, receipt date, or invoice date are three different dates that can differ by weeks. Specify which one.
.Milestone payments following progress. Used for fabrication, installation, and projects that run for months. Each stage must have verifiable markers, not just a percentage of time. "After functional testing is accepted" is much safer than "after 50 percent completion", as the latter cannot be proven by anyone.
Retention. A small portion of the value is withheld until the warranty period or testing period passes, then paid. Useful for items whose defects only become apparent after use. There's one condition: the release date must be clear, otherwise it turns into a source of dispute that costs more time than the value withheld.
For purchases from suppliers you have never used before, especially imports, two additional tools are worth considering: letters of credit through a bank, and escrow accounts. Both transfer some risk to a third party at a certain administrative cost. For small values, the cost is often not worth it, but for a first large order with an unknown party, it is much cheaper than losing the entire advance payment.
The actual risks you bear
Each structure transfers risk; it does not eliminate it. Only who holds it changes.
The larger the advance payment, the greater the credit risk you take on the supplier. You are betting that the company will still be standing and able to deliver when the time comes. Therefore, a large advance payment only makes sense to a party you have already vetted. How to vet them is discussed in ten ways to verify a supplier before a deal.
The longer the payment terms you request, the narrower the list of capable suppliers. Small companies often do not have the breathing room to wait two months, and they will silently refuse by not responding. Long terms are not a win if the only suppliers left are the most expensive ones.
Payment terms you never meet are more expensive than shorter terms. Payment reputation sticks to a company's name and spreads quickly in industries with few players. Once you are known to be late, the prices you receive will adjust, and the terms previously given will be withdrawn.
Retention and milestone payments add administrative work. Someone needs to remember the release dates and verify each stage's markers. If no one is assigned, retention turns into forgotten debt and a damaged relationship.
Align with your own cash cycle
The correct question is not "what are the longest terms I can get", but "when will the money to pay for this actually come in". If the goods are used for a project that will only be invoiced after handover, paying in full upfront means you are financing that project with your own cash for months.
Therefore, before setting terms in an RFQ, look at two dates: when you have to pay the supplier, and when you receive money from the work using those goods. The gap between the two is the burden you bear yourself. Good payment terms shorten that gap, not lengthen it, and sometimes the solution is not longer terms but a broken-down delivery schedule so that invoices arrive in stages.
One thing often overlooked: faster payment has an exchange value. If your cash flow is ample, offer faster payment and ask for a price that reflects it. Many suppliers are willing to lower prices for earlier money, because for them, cash certainty is often more valuable than a slim margin difference.
What makes suppliers willing to grant terms
Payment terms are granted based on trust, and that trust is built on verifiable things. What suppliers usually assess before giving terms:
Transaction history. First orders almost always get the strictest terms. That's normal, not an insult. The way to improve this is to complete the first small order with on-time payment, then request terms for subsequent orders.
Completeness of documents. Official purchase orders, clear billing addresses, and complete tax documents allow your invoices to be processed without back-and-forth. Suppliers whose invoices are often held up by administration will think twice before giving terms.
.Order size and regularity. Buyers who order regularly are more likely to get terms than one-time buyers of the same value, because the repeated relationship itself acts as a guarantee.
Clarity of decision-maker. Suppliers want to know who approves payments on your side. A convoluted approval process without a clear responsible party is the most common reason for late invoices, and experienced suppliers can smell it from the start.
Writing it in the RFQ so offers remain comparable
All of the above is useless if the terms only appear after offers come in. State the terms you offer in the request, aligned with specifications and schedule, like other elements discussed in the guide writing unambiguous RFQ specifications.
Two sentences are usually enough. The first states your terms, the second opens up space: state that suppliers may propose different terms provided they mention them along with their impact on the price. That second sentence turns terms from a command into information you can compare.
If the value is large and you truly want to see the cost of money, ask for two figures at once: the price with the terms you offer, and the price if paid faster. The difference between the two is the cost of those terms, openly stated by the supplier themselves. That figure is much more useful than guessing, and often surprises both parties.
Five expensive mistakes
Stating "30-day terms" without the calculation point. Thirty days from shipment, receipt, or invoicing can differ significantly. This ambiguity is almost always resolved in a way that is not advantageous to you.
Equating terms for all types of spending. Stock items, custom-ordered items, and installation services have different risk profiles. A single policy enforced across all will be too lenient on one side and scare away suppliers on the other.
Paying a large advance to an unverified party. This is not about suspicion, but about order: verify first, then transfer. Once the money has moved, all the tools you have left are pleas.
Promising terms that internal processes cannot meet. If payment approval in your company takes two weeks, promising seven-day payment only creates a scheduled breach.
Forgetting retention. The withheld value still belongs to the supplier. Not releasing it on time is the cheapest way to lose a good supplier.
Checklist before setting terms
Is the due date calculated from shipment, receipt, or invoice issuance, and is it written?
When will the money to pay for this actually enter your cash flow?
Is the advance payment amount still reasonable if the supplier fails to deliver?
Has the supplier been verified before the advance payment is transferred?
If there are milestone payments, does each stage have a verifiable marker, not a percentage of time?
If there is retention, who remembers the release date?
Can your internal approval process meet the terms you promise?
Have these terms been written into the request for quotation, rather than saved for later negotiation?
Decide upfront, not at the end
Payment terms have a troublesome nature: they feel like an administrative matter, yet they change the price, change who is willing to bid, and change who bears the risk if something goes wrong. Because they feel administrative, they are often left until the end, and by then all your bargaining power has been used up negotiating other things.
Set them once as policy, differentiate by spending type, then write them in every request from the first sentence. The work is done upfront, and the incoming offers will stand on the same ground.
