Most of the attention in government buying goes to the moment before award: the solicitation, the quotes, the evaluation. For the people who have to receive the goods, the hard part starts after award. Will the right item show up, at the right dock, with paperwork the receiving office can match to the order? And if something goes wrong, will the supplier find out first and tell you, or will you find out at the dock?
This guide is written from the supplier's side of that handoff. It lays out what a contracting officer, contract specialist or purchase cardholder should expect from a commercial supplier after award, in the order it should happen. Use it as a checklist for new vendors, or as a yardstick for the ones you already use.
The short version
| Stage | What you should get from the supplier | When |
|---|---|---|
| Acknowledgment | Written confirmation of every line: item, quantity, ship-to, delivery date, point of contact | Within one business day of the order |
| Sourcing check | Confirmation the exact items are available, or an early warning that one is not | Before anything ships |
| Compliance paperwork | Country of origin by line, required representations, authorization letters where the order calls for them | With the acknowledgment, or before shipment |
| Shipping notice | Tracking for every shipment, with partial shipments labeled as partial | The day each shipment leaves |
| Receiving support | A fast replacement or correction plan if anything arrives damaged or wrong | Within one business day of your notice |
| Invoice | A proper invoice that matches the order line for line, sent only after delivery | After delivery, through the method your contract names |
| After the sale | One contact for warranty claims, returns and questions | For the life of the warranty |
The rest of this article explains each stage, what can go wrong at it, and what a good supplier does about it.
1. A written acknowledgment, line by line
The first thing you should receive after an order goes out is an acknowledgment. Not a "thanks, got it," but a line-by-line confirmation that repeats back the order number, each line item with its quantity and unit, the ship-to address, the required delivery date and a named person you can call.
This sounds like paperwork for its own sake. It isn't. The acknowledgment is where mismatches get caught cheaply. The most common one we see: the statement of work numbers the items one way and the pricing schedule or order form numbers them another. If a supplier prices or ships against the wrong numbering, the government ends up with the right products attached to the wrong line numbers, and the receiving report, the invoice and the payment all stop matching. A supplier that reads the order back to you line by line will spot that on day one.
What to look for:
- Every line from the order appears in the acknowledgment, with no lines merged or dropped.
- The ship-to address is the delivery point in the order, not the contracting office's mailing address.
- The delivery date is stated as a date, not as "standard lead time."
- Anything the supplier is unsure about is raised as a question, not assumed.
2. A sourcing check before anything ships
A commercial supplier, especially a reseller, is buying from a manufacturer or distributor to fill your order. Between the quote and the award, things change. Models get discontinued, a color goes on backorder, a manufacturer changes a part number.
A good supplier confirms availability of the exact items on your order before it ships anything, and tells you right away if something has changed. What it should never do is substitute an item silently and let you discover the difference at the dock. If the ordered item is no longer available, you should get the facts, the closest equivalent with its specifications side by side, and a request for your decision. Only the contracting officer can agree to a change in what the contract buys. A supplier that ships an "equivalent" without asking has handed you a nonconforming delivery and a problem you did not create. We cover the details in substitutions and discontinued items.
The same applies to timing. If one line will be late, you should hear it as soon as the supplier knows, along with a new date and an offer to ship the rest now if your order allows partial deliveries. See partial shipments on government orders.
3. Compliance paperwork up front, not on request
Commercial products bought by the government come with compliance questions that a retail buyer never asks. A supplier that does this work regularly sends the answers before you have to chase them:
- Country of origin, by line. If your order is subject to the Trade Agreements Act or the Buy American statute, the supplier should know and state where each item was made. Not "TAA compliant" stamped across a whole quote, but a country for each line. Our country of origin guide explains which rule applies when.
- Section 889 representation. Federal buyers are barred from buying certain covered telecommunications and video surveillance equipment. The supplier should have its representation on file in SAM and be ready to answer for the specific items on your order. See what a supplier certifies under Section 889.
- Manufacturer authorization. When an order names a brand, or the solicitation required an authorized source, the supplier should have the manufacturer's letter of authorization in hand before quoting, and should send you a copy without being asked. See letters of authorization.
- No sales tax. Purchases by the federal government are generally exempt from state sales tax. Tax should not appear on the invoice, and a supplier that adds it creates a correction cycle for your office. A few states use gross receipts or similar taxes that work differently, so if you see a tax line, ask what it is. See federal tax exemption from the supplier's side.
4. Shipping notices you can match to the order
Once goods move, you should get a notice for every shipment: carrier, tracking number, the order lines and quantities in that box or pallet, and the expected delivery date. If a shipment is partial, it should say so in plain words and list what is still to come.
The packing slip inside the shipment matters as much as the email. Receiving staff match deliveries to orders using whatever is on the label and the slip. The slip should show the government order number and the line numbers from the order, not just the manufacturer's part numbers. Many suppliers drop-ship directly from the manufacturer, which is efficient but means the manufacturer's warehouse prints the slip. A careful supplier tells the warehouse exactly what to print. We walk through it in drop-shipping to a federal agency.
Two more details that separate experienced suppliers:
- Secured facilities. Many federal buildings and installations will not accept a delivery without advance notice, a named recipient or an appointment. The supplier should ask about delivery restrictions at acknowledgment, not when the truck is at the gate.
- Risk in transit. Most supply orders are delivered "F.o.b. destination" under FAR 52.247-34. In plain terms, the supplier carries the risk of loss or damage until the goods are delivered to the destination in the order. If a shipment arrives crushed, that is the supplier's claim to manage with its carrier, not the government's. See FOB destination for receiving staff.
5. Fast help when a delivery is wrong
Sooner or later, something will arrive damaged, short or different from the order. What matters is how quickly the supplier makes it right.
For commercial items, the standard clause is FAR 52.212-4, Contract Terms and Conditions, Commercial Products and Commercial Services. Under paragraph (a), the supplier may only tender items that conform to the contract, and the government may require repair or replacement of nonconforming items at no increase in price. The government's rights after acceptance have to be used within a reasonable time after the defect was discovered or should have been.
In practice, a good supplier responds to a problem report within one business day with three things:
- An acknowledgment of what went wrong, without arguing about whose fault it was.
- A replacement plan with a date, at no cost to the government.
- A return label or pickup arrangement for the wrong or damaged goods, so your dock is not stuck storing them.
What you should not have to do is chase. If you are writing the second email about the same broken item, the supplier has failed this stage. Our receiving and acceptance guide covers how to document a rejection so the fix is quick.
6. An invoice that matches, sent at the right time
A supplier should invoice after delivery, not before, unless your contract allows something else. The invoice should go through whatever method the contract names, which is usually an electronic invoicing system, and it should match the order line for line.
Paragraph (g) of FAR 52.212-4 lists what a proper invoice contains, including the contract and order numbers, the line item numbers, a description, quantity, unit and extended price for each item, shipping details, and a contact for questions about a defective invoice. When an invoice is missing something, the paying office returns it, and under the Prompt Payment rules at 5 CFR 1315.4 the agency should send that notice within 7 days of receiving the invoice.
Payment is generally due 30 days after the government receives a proper invoice, unless the contract sets a different date. For most deliveries, the invoice is treated as received no earlier than the seventh day after delivery, or the date of acceptance if the agency accepts sooner. That is the rule. The practical point for buyers is simpler: an invoice that matches the order and the receiving report gets paid on time, and one that does not costs everyone a cycle of corrections. A supplier who has done this before sends the first kind.
7. One contact after the sale
The relationship does not end at payment. Under paragraph (o) of FAR 52.212-4, the supplier warrants that delivered items are merchantable and fit for the use described in the contract. Many products also carry a manufacturer's warranty.
When a unit fails six months later, the end user should not have to work out whether to call the reseller, the distributor or the manufacturer. The supplier should be the single point of contact: it takes the report, opens the claim with the manufacturer, and arranges the repair or replacement. If you bought through a reseller that is authorized by the manufacturer, the manufacturer's warranty normally passes through to you. That is one of the practical reasons authorization matters. See warranty on resold equipment.
Red flags after award
Most supplier problems give warning signs early. Watch for these:
- No written acknowledgment, or one that just says "order received."
- Questions about the order arriving the week the delivery is due.
- "Equivalent" items showing up without a request to substitute.
- Packing slips with only the manufacturer's part numbers, so receiving cannot match the delivery.
- Sales tax on a federal invoice.
- An invoice sent before delivery, or with prices or quantities that differ from the order.
- A different contact person every time you call, or no answer at all.
None of these means the supplier is acting in bad faith. They usually mean a supplier is new to government work. But each one costs your office time, and the pattern tends to repeat.
How Lunula Supply handles it
We are a small business supplier, and most of what we deliver is sourced from manufacturers and distributors and shipped direct to the agency. Because we sit between the government and the factory, the checklist above is how we run every order:
- We confirm each order line by line in writing and raise mismatches on day one.
- We verify availability of the exact items before anything ships, and we ask before any substitution.
- We keep a running order report for each award, so partial shipments, backorders and tracking are visible in one place.
- We send country of origin, authorization letters and representations with the order, not after a request.
- We invoice after delivery, through the system the contract names, matched to the order and the receiving report.
- One person stays your contact from acknowledgment through warranty.
If you buy supplies and want a supplier that works this way, contact us or see what we supply.
Frequently asked questions
How quickly should a government supplier acknowledge an order?
Within one business day is a reasonable expectation for a commercial supplier. The acknowledgment should confirm every line, the ship-to address, the delivery date and a named contact, so mismatches can be fixed before anything ships.
Can a supplier substitute an equivalent item without asking?
No. Only the contracting officer can agree to a change in what the contract buys. If the ordered item is unavailable, the supplier should explain the problem, propose an equivalent with its specifications, and wait for a decision before shipping it.
Should sales tax appear on an invoice to a federal agency?
Generally no. Purchases by the federal government are generally exempt from state sales tax. If a tax line appears, ask the supplier what it is, because a few states apply gross receipts or similar taxes that work differently from a sales tax.
When does the government have to pay a supplier's invoice?
Under the Prompt Payment rules, payment is generally due 30 days after the government receives a proper invoice, unless the contract sets a different date. For deliveries, the invoice is usually treated as received no earlier than the seventh day after delivery, or the acceptance date if earlier.
