MOQ (minimum order quantity)
MOQ is the smallest quantity a supplier will agree to manufacture or ship per order. Suppliers set MOQs to make a production run economically worthwhile for them: setup time, tooling changeover, raw-material lots. For the buyer, MOQ is a cash-flow and inventory tax that shapes how often you order and how much you carry.

How it works in practice
Production needs 200 units of a machined part this month. The supplier's MOQ is 500. You have three options: order the 500 and carry the extra 300 as inventory until the next pull, qualify a second source with a lower MOQ, or negotiate an MOQ buyout (you pay a setup premium and get the 200). Most buyers take the first option because it is the fastest, and accept that the next two months of demand for that part are already on the shelf.
MOQ behavior varies by part type. A custom machined part has a real MOQ tied to setup time on a CNC. A stamped part has an MOQ tied to die-cycle economics. A catalog SKU from a distributor often has a low MOQ at the distributor and a much higher MOQ at the original manufacturer. Knowing which kind of MOQ you are dealing with is what makes negotiation possible.
A senior buyer treats MOQ as a number to negotiate, not a constant. First-article runs and qualification orders often run below MOQ. Repeat orders for known parts can sometimes drop the MOQ if the supplier sees steady follow-on volume. The number on the quote is the starting position.
Why it matters
MOQ-driven over-ordering is a hidden cost that does not show up on a single PO but compounds across hundreds. Ordering 500 instead of 200 every cycle ties up cash, takes up floor space, and creates obsolescence risk if the part is ever revised. The MOQ tax is real, and on a portfolio of mid-volume parts it can be the difference between a healthy working-capital number and a stressed one.
MOQ also shapes the open-PO list. Ordering in larger batches means fewer POs but longer lead times between releases, which means a missed delivery has a bigger consequence. The buyer trades order frequency for delivery risk per order.
Tips
Ask for the real MOQ, not the quoted one
The MOQ on a quote is often the supplier's preferred quantity, not their minimum. Ask what the actual minimum is for a repeat order or a small premium and you will frequently get a lower number.
Use a blanket PO to spread the MOQ
A blanket PO with monthly releases lets you commit to the MOQ across a full year while only taking delivery of what you need each month. The supplier gets the volume; you avoid the inventory hit.
Track the MOQ tax in dollars, not units
Once a quarter, look at the parts where you regularly order above demand because of MOQ and convert the over-order into a dollar figure. It is the number that justifies negotiating, qualifying a second source, or revisiting the part design.
How PO-Relay helps
PO-Relay tracks the open POs that result from MOQ-driven ordering: every release on a blanket PO, every one-off order placed at the MOQ rather than at demand. Open Loop Tracking watches each one through the lifecycle, the Parts Dashboard shows the live state of every release, and the morning briefing surfaces the at-risk ones so a delayed MOQ shipment does not turn into a line-down on a part you over-ordered to begin with.
PO-Relay does not store supplier MOQs as a first-class field or run negotiation analysis. The MOQ itself, the unit-cost math, and the cash-flow trade-off live in your ERP or sourcing tools. PO-Relay's contribution is making sure the deliveries that the MOQ created actually land on time.
