A request for quotation (RFQ) is a formal document a buyer sends to one or more potential suppliers asking for a price, lead time, and terms on a specific item or item list — before any commitment to buy. In a closed-loop procurement workflow — where demand signals, purchase orders, supplier replies, receiving, and accounting handoffs run in one connected system — the RFQ is the pre-commitment step that generates the supplier data the rest of the loop runs on: quoted lead time for reorder point math, stated MOQ for order quantity planning, and payment terms for cash conversion modeling.
Quick answers
What is an RFQ? A request for quotation (also called a supplier quote request or price quote request) is a document sent to one or more suppliers asking for their price, minimum order quantity, lead time, and payment terms on a defined list of items. Unlike a purchase order, an RFQ is not a commitment — it is a formal inquiry. The supplier's response is a quote. The buyer evaluates the quote, and if it is acceptable, converts it into a purchase order.
What is the difference between an RFQ and an RFP? A request for quotation is used when the item is known and the buyer is comparing price and terms across suppliers. A request for proposal (RFP) is used when the requirement is less defined — the buyer is describing a need and asking suppliers to propose how they would meet it. RFQs are appropriate for commodity and repeat-purchase goods; RFPs are appropriate for complex services, custom manufacturing, or situations where the approach matters as much as the price.
What is the difference between an RFQ and a purchase order? A purchase order is a legally binding commitment to buy. An RFQ is a non-binding inquiry. A well-run procurement cycle uses the RFQ to collect competing quotes, selects a supplier, and then issues a purchase order — at which point the commitment is made and the closed-loop order cycle begins.
Do SMBs need formal RFQs? Not always. For established supplier relationships with documented performance data — fill rate, lead-time accuracy, purchase price variance history — the existing record provides the basis for ordering without re-soliciting quotes on every cycle. RFQs are most valuable when entering a new category, replacing a failing supplier, adding a secondary source, or when performance data shows a supplier's pricing has drifted enough to warrant re-evaluation.
How formal does an RFQ need to be? For SMBs, an RFQ can be as simple as a structured email listing the items, quantities, and the specific information requested: unit price at the intended order quantity, lead time, MOQ, and payment terms. The format matters less than completeness — an RFQ that does not ask for lead time will receive quotes that do not include it, and lead time is a direct input to reorder point math.
RFQ vs RFP vs purchase order
| Document | What it asks | Buyer obligation | Supplier obligation | When to use |
|---|---|---|---|---|
| RFQ | Price, lead time, MOQ, payment terms for defined items | None — non-binding inquiry | Submit a quote if interested | New suppliers, re-sourcing, competitive review |
| RFP | How the supplier proposes to meet an open-ended need | None — non-binding solicitation | Propose an approach and pricing | Complex services, custom requirements, undefined scope |
| Purchase order | Fulfillment of specified items at agreed price and terms | Legal commitment to pay on delivery | Legal commitment to supply | All production orders with established suppliers |
The practical sequence for a new supplier relationship: RFQ → quote evaluation → supplier selection → purchase order. For established relationships with documented performance, the RFQ step is replaced by the existing supplier record — lead time, pricing, and MOQ are already known and verified across prior order history.
What goes in an RFQ
An RFQ that produces usable, comparable supplier responses needs to be specific about what you are asking for.
Required fields:
- Item descriptions: SKUs, product names, specifications, units of measure — enough detail that the supplier quotes on exactly what you need, not an approximation
- Requested quantity: The quantity you are considering ordering, stated explicitly. Supplier pricing often changes at quantity thresholds; quoting against your actual intended order size produces actionable numbers
- Delivery location: Where goods need to arrive. Freight terms and shipping costs vary significantly by location and supplier
- Required lead time: How quickly you need goods after placing an order. If a supplier cannot meet your lead time, you need to know before onboarding
- Requested response deadline: When you need the quote. Suppliers who do not respond by the deadline self-select out of consideration
Optional but useful fields:
- Payment terms preference (Net 30, Net 60, early payment discount structure)
- MOQ flexibility question: "We anticipate ordering X units per cycle — is that above your minimum order quantity?"
- Volume commitment framing: "We expect to purchase approximately X units per quarter — what pricing does that volume support?"
- Secondary source context: "We are qualifying a secondary supplier for this category. What would your pricing be for 20–30% of volume?"
Stating the volume context — not just the one-time order quantity — often produces better pricing than an isolated spot quote, because suppliers price for the relationship, not the single order.
When SMBs actually need an RFQ
Qualifying a new supplier. When adding a supplier you have never bought from, an RFQ collects the basic data that belongs in the supplier record before the first order: unit pricing at realistic quantities, stated lead time, MOQ, and payment terms. Even if there is only one candidate supplier in a category, a structured quote request creates a written record of what was agreed — the baseline that gets verified against on the first order.
Re-sourcing under performance failure. If the supplier scorecard for a current supplier shows fill rate below 90% on A-items, consistent lead time misses, or unfavorable purchase price variance trends, re-evaluating the market is warranted. An RFQ sent to alternative suppliers produces comparable data against which the current supplier can be measured, and creates optionality if the relationship needs to be replaced.
Adding a secondary source. Dual sourcing starts with qualifying a second supplier — which means sending an RFQ to candidates and evaluating their responses against the primary supplier's documented performance. A secondary source with worse pricing and longer lead times than the primary may still be worth qualifying if supply risk is high enough; the RFQ data quantifies the cost of that insurance.
Tariff-driven or supply-chain-driven re-sourcing. When tariff changes, import restrictions, or supply disruptions make the current supplier's economics materially worse, a market RFQ re-establishes what alternative pricing looks like. The comparison is not just unit price — it is unit price plus lead time change plus MOQ adjustment plus the switching cost of onboarding a new supplier.
When a PO is enough
An RFQ is not necessary for every supplier or every order cycle. For established supplier relationships where the procurement record is current — pricing confirmed in the last 6–12 months, empirical lead times measured across at least five orders, fill rate tracked — the existing data replaces the need for a fresh quote. Issuing an RFQ to a supplier you have been buying from for 18 months, whose pricing is documented and whose performance is tracked, signals uncertainty about a relationship that is otherwise stable.
The decision framework: use an RFQ when you are evaluating a supplier you have not ordered from, when you are re-evaluating a supplier whose terms or performance have materially changed, or when you are entering a category where no current supplier data exists. Use a purchase order when you are ordering from an established supplier whose record is current.
Evaluating supplier responses
A useful RFQ response contains unit price at the requested quantity, stated lead time, MOQ, and payment terms. When comparing multiple responses, the evaluation needs to run across all four dimensions, not just price.
Unit price vs. actual consumption. A lower unit price that only applies above a quantity you cannot practically order is not a better offer — it is a discount on a constraint. Evaluate price at your realistic order quantity, not the supplier's best-case volume tier.
Lead time vs. reorder point math. Lead time from the quote is an input to the reorder point formula: ROP = (consumption rate × lead time) + safety stock. A supplier quoting two-day shorter lead time at the same price reduces the inventory buffer needed to cover that supplier, reducing carrying cost. Price and lead time are not independent variables.
MOQ vs. economic order quantity. If the supplier's MOQ exceeds the quantity your economic order quantity calculation supports, the quoted pricing comes at the cost of excess inventory. The carrying cost of that excess is real — a favorable unit price at an unfavorable MOQ may be worse than a slightly higher unit price at an MOQ that fits your consumption rate.
Payment terms vs. cash conversion. Net 60 from a supplier with marginally higher unit prices may produce better cash flow than Net 30 from a supplier with slightly lower prices. Payment terms affect days payable outstanding and the business's cash conversion cycle — they belong in the comparison, not just the price column.
How supplier scorecards replace periodic RFQs
A documented supplier relationship, actively tracked, eliminates most recurring RFQs. When you know — from the procurement record, not from memory — that a supplier has delivered at 97% fill rate over the last 24 orders, at prices within 1.2% of agreed PO pricing, at an empirical lead time of 4.3 days against a quoted 5, you do not need to re-quote the market to decide whether to continue the relationship. The scorecard makes the decision.
The four metrics that replace periodic re-evaluation:
- Fill rate: units received / units ordered. Below 90% on A-items is a re-sourcing signal.
- Lead-time accuracy: empirical lead time vs. quoted lead time. A supplier who consistently delivers in 7 days against a quoted 5 requires 2 extra days of safety stock on every cycle.
- Purchase price variance (PPV): invoice price vs. PO price. Unfavorable PPV that appears systematically — not as a one-time exception — indicates the pricing agreement is not holding.
- Substitution rate: orders with item substitutions / total orders. Above 5% on a consistent basis signals catalog instability or supply constraints.
When any of these metrics crosses a threshold — fill rate below 90%, consistent lead time misses, systematic unfavorable PPV, substitution rate above 5% — an RFQ to alternative suppliers is the appropriate response. Below those thresholds, a current supplier with documented performance is the right choice without re-soliciting the market.
How LineNow handles it
LineNow's workflow begins when a supplier has been selected and the supplier record is set up — the RFQ is a pre-onboarding step that happens before the first purchase order. But the data that makes RFQ evaluation and re-evaluation meaningful — fill rate, lead-time accuracy, PPV, substitution rate — is captured automatically as a byproduct of the buying workflow.
When it is time to re-evaluate a supplier or qualify a second source, the supplier scorecard is already there: built from real order history, not from memory. The comparison against a new supplier's RFQ quote runs against documented performance data, which makes the evaluation specific rather than impressionistic.
