A matcha supplier scorecard is a quarterly record of what a supplier actually delivered, documented, and corrected. For a B2B buyer, a beautiful approval sample says little about three late shipments, missing certificates of analysis, or unresolved complaints. Build the scorecard from receiving and quality records, agree on definitions with the supplier, and review exceptions before the next purchase commitment. The supplier selection guide covers initial screening; this worksheet tracks performance after approval. The American Society for Quality’s supplier guide identifies delivery, acceptance, corrective actions, and response time as useful measures. Your own thresholds should reflect product risk and service needs.

1. What belongs on a matcha supplier scorecard?
Separate performance from approval
An approval file records capability at a point in time. A scorecard records whether deliveries meet agreed requirements over a defined period. Keep five categories: delivery, documentation, product conformity, complaint handling, and communication. State one measurable numerator and denominator for each. A category without an observable event, such as “professionalism,” invites arguments rather than improvement. Keep current certification checks in the approval file and note any expiry as an exception; a scoring average must never make an absent required document acceptable.
| Category | Unit of observation | Primary evidence |
|---|---|---|
| Delivery | Order line received on agreed date | Purchase order, receipt |
| COA | Lot with complete agreed report | COA, lot specification |
| Deviation | Received lot outside agreement | Inspection and disposition |
| Complaint closure | Case closed with evidence | Complaint register |
| Response | Request answered within target | Dated correspondence |
Start with evidence. Matcha Village describes batch traceability and sample support in its company background, but a buyer should still request records for its own lots. Score actual transactions, not marketing claims. Publish the calculation rules before the quarter starts so both parties can check a disputed entry.

2. Which order and lot records form the baseline?
Make every row traceable
Trace each receipt. Create a transaction sheet with order number, SKU, grade, supplier lot, buyer receipt lot, ordered quantity, promised ship date, actual ship date, arrival date, and receiving disposition. Link each row to a COA version. If one order ships in three lots, give each lot its own document and conformity row while retaining a common order reference. That prevents a complete report for one lot from hiding a missing report for another. Retain an original promise date and a separately approved revision; never silently overwrite the first date after a delay.
The FDA’s traceability guidance describes links between lot codes and relevant records for foods covered by its rule. Its scope depends on the food and business, so treat lot linkage here as a sound operating practice rather than a claim that the rule automatically covers matcha. For a trial, reconcile the last three receipts against purchase orders and COAs. Count unmatched lots before choosing a score. A clean denominator matters more than an elaborate dashboard with missing shipments.
3. How should on-time delivery be calculated?
Choose the event before measuring
Define “on time” as arrival at the agreed receiving site, supplier dispatch, or availability for collection under the agreed trade term. These measure different obligations. For an importer with a long ocean leg, dispatch performance and arrival performance can be shown separately. Count each committed order line once and define whether partial quantity qualifies. An illustrative rule counts a line on time only when the agreed quantity arrives within the agreed date window; test this rule with both parties before adopting it. On-time rate equals qualifying lines divided by committed lines, multiplied by 100.
| Example line | Agreed event | Actual event | Quantity complete? | Trial result |
|---|---|---|---|---|
| A | Week 10 receipt | Week 10 receipt | Yes | On time |
| B | Week 11 receipt | Week 12 receipt | Yes | Late |
| C | Week 12 receipt | Week 12 receipt | No | Partial |
Check the exception. Record a buyer-requested reschedule separately from supplier-caused delay. Do not delete it. The ASQ supply chain primer uses quarterly delivery and quality report cards, supporting regular measurement; it does not prescribe one matcha-specific delivery window. Compare trends and missed launch dates alongside the percentage.

4. What makes a COA complete?
Score the agreed document package
Check the actual report. Before an order, define which results belong on each lot-specific certificate of analysis: supplier lot ID, test date, method or laboratory, specification limit, numeric result or justified qualitative result, and authorized release status. Parameters depend on the application and destination market. The buyer’s quality and regulatory teams should approve that list; a generic online checklist cannot establish a legal limit. Count a COA complete only when all agreed fields arrive before the buyer’s release decision. A late correction can close the issue but should remain visible in the quarter when the delay occurred.
| COA check | Pass rule for trial | Evidence |
|---|---|---|
| Identity | Report lot equals received lot | Label and COA |
| Scope | Agreed tests present | Signed specification |
| Result | Values and units legible | COA page |
| Timing | Available before release | Receipt timestamp |
The FDA supplier verification resource explains that regulated facilities and importers may have risk-based verification duties. A COA score is a useful commercial control, not a substitute for a required verification activity. Ask who reviewed a revised COA and whether material remained on hold during the correction.
5. How do batch deviations enter the score?
Count events and their consequence
A deviation occurs when a received lot misses an agreed specification or required handling condition. Record what failed, how many kilograms were affected, who discovered it, and whether material was rejected, reworked, conditionally accepted, or held. Keep sensory variation separate from a documented safety concern, since the response and investigation differ. A simple deviation rate is nonconforming received lots divided by received lots. For small quarterly volumes, show the raw count beside the percentage: one failure among two lots means 50%, but the sample is tiny.
The decision log should also capture color drift, taste mismatch, packaging damage, and labeling errors when those attributes are in the purchasing agreement. Compare like with like: culinary powder for baking should not inherit a ceremonial drinking specification. Use the buyer’s signed specification as the anchor, then review the same lot’s retained sample and COA if a discrepancy appears. A score needs context. One severe event may require immediate containment regardless of a high overall score. Keep this override rule written and distinct from weighted arithmetic.

6. How should complaint closure be rated?
Require evidence of an effective response
Closure needs proof. Define a complaint as an identified product or service concern linked to an order or lot. Record date opened, affected quantity, immediate containment, investigation owner, root-cause evidence, corrective action, and verification of effectiveness. “Closed” should mean the agreed evidence has been reviewed, not merely that a supplier emailed an apology. For the score, measure both median days to closure and cases overdue against an agreed case priority. A proposed trial target might give a packaging-damage claim ten business days for an initial investigation; the appropriate period depends on severity and test turnaround.
| Complaint field | Useful decision question | Record owner |
|---|---|---|
| Lot and location | Which stock can be isolated? | Buyer quality |
| Immediate action | Was further use paused if needed? | Both parties |
| Cause evidence | Does evidence explain the failure? | Supplier quality |
| Effectiveness | Did later lots avoid recurrence? | Joint review |
The ASQ supplier handbook excerpt lists corrective-action response and resolution time as scorecard measures. Make the operational decision explicit: purchasing may continue, pause, or require added checks while the case remains open. A numerical score alone cannot decide disposition of suspect stock.
7. What does supplier response time reveal?
Measure answers that unblock work
Response time starts when a complete buyer request reaches the agreed contact and ends when the supplier provides an answer that lets the buyer act. An automatic acknowledgment should not count as an answer to a missing COA or urgent lot question. Separate routine requests from urgent shipment or quality issues. For example, a trial service agreement could ask for an initial quality contact within one business day and a dated investigation plan after triage; these are suggested negotiation points, not industry standards. Record holidays and time zones so the measure stays fair.
| Request type | Start event | Stop event | Trial metric |
|---|---|---|---|
| COA correction | Specific defect sent | Correct report received | Business hours |
| Lot trace | Lot IDs supplied | Linked records returned | Business hours |
| Ship update | Dispatch question sent | Confirmed milestone | Business hours |
Look beyond speed. A fast but incorrect answer can delay a release twice. Sample five exchanges and check answer completeness as well as elapsed time. If a buyer changes the question midstream, log a new request rather than stretching the supplier’s clock. Written definitions make a later review less personal and more useful.

8. How do you calculate a weighted quarterly result?
Show the math and the raw facts
Choose weights before results are known. A sample worksheet below gives conformity and documentation greater weight than communication because an unusable lot or missing release record can block production. These weights are suggested trial settings. Score each category from zero to 100 using agreed bands, multiply by its weight, and add the contributions. For example, 90 delivery points at a 20% weight contributes 18.0 points. Do not bury the underlying numerator and denominator; attach a one-page event ledger to the summary.
| Category | Trial weight | Example score | Weighted points |
|---|---|---|---|
| Delivery | 20% | 90 | 18.0 |
| COA completeness | 25% | 80 | 20.0 |
| Lot conformity | 30% | 95 | 28.5 |
| Complaint closure | 15% | 70 | 10.5 |
| Response | 10% | 85 | 8.5 |
| Total | 100% | — | 85.5 |
Keep a hard stop. A missed mandatory document or unresolved serious deviation should trigger the relevant quality procedure even if the arithmetic result is 85.5. The ASQ scorecard program demonstrates weighted supplier categories and formal quarterly review, but its weights came from another industry. Treat this worksheet as a starting design to validate against your risk profile.
9. What action follows a deteriorating score?
Escalate by cause and repeatability
Follow the cause. Plot three or four quarters, then inspect the event log behind a decline. A fall from 94 to 84 could represent repeated small delays, one rejected lot, or slow complaint closure. Those need different responses. Agree on a trial trigger, such as two consecutive declines or a score below an agreed band, and pair it with a meeting date. Ask for a corrective-action plan with owner, due date, evidence of completion, and a check on the next comparable shipment. If the issue concerns missing paperwork, verify a future COA before dispatch. If arrival timing failed, review the shipping milestone that slipped.
| Signal | Practical buyer action | Evidence at next review |
|---|---|---|
| Repeated late lines | Request dated recovery plan | New delivery records |
| Incomplete COAs | Hold release until corrected | Complete lot reports |
| Repeated deviation | Reassess specification and process | Inspection trend |
| Open complaints | Escalate to quality leads | Closure and effectiveness |
Do not use a scorecard to waive a receiving hold or replace supplier approval requirements. If risk changes, the buyer’s quality team decides whether enhanced verification, reduced allocation, or suspension is appropriate under its own procedures. Give the supplier a chance to challenge data with documents, then preserve the final agreed version.

10. How should buyers run the quarterly review?
Leave with decisions and dates
End with a decision. Send the draft matcha supplier scorecard before the meeting. Include every denominator, disputed record, missing document, and open complaint. Procurement can explain forecast and ship-date changes; quality can explain holds and deviations; the supplier can bring production and investigation records. Work through exceptions first, then agree on each score and corrective action. Keep a written record of who approved the final version. A chart without a decision has little value to a buyer planning the next quarter’s stock.
Set the next review date and ask what evidence will demonstrate improvement. For Matcha Village or any other supplier, request a sample and batch document package for the exact grade and intended application. If buying spans several SKUs, keep lot-level records and show a consolidated view only after checking each SKU’s performance. The practical next step is a three-month pilot with agreed definitions, followed by a revision of weights and thresholds based on real events. That gives both teams a fair basis for future purchase commitments.
A weak quarterly score should lead to a documented response; the supplier corrective action guide shows the related follow-up process.
FAQ
Q1: What is a matcha supplier scorecard? A quarterly summary of documented delivery, COA, conformity, complaint, and response performance against agreed definitions.
Q2: Should price appear in the score? Track price and landed cost, but keep quality holds and mandatory documentation visible as separate decisions.
Q3: How many deliveries make a score useful? Show raw counts and percentages; a quarter with few lots needs cautious interpretation.
Q4: Can a strong total cancel a serious deviation? No. Handle suspect material through the buyer’s quality procedure regardless of total points.
Q5: When should weights change? Review them after a pilot or material risk change, then set new weights before the next scoring period.
