Procurement and Supplier Relations

Supply and Supplier Relations

Chapter Introduction

This chapter covers all the skills related to supply and supplier relations, as assessed under the Red Seal exam for the parts technician trade. You will learn about purchasing processes, supplier selection, order management, receiving, quality control, as well as the management of returns and warranties. Mastering these concepts is essential to pass the exam and to practice the trade effectively.

The Fundamentals of Supply

Definition and Scope

Supply (or procurement) is the process by which a company obtains the goods and services needed for its operations. For a parts technician, this includes:

Identifying needs (internal or customer)

Researching and selecting suppliers

Negotiating prices and terms

Placing orders

Tracking delivery

Receiving and inspecting goods

Managing discrepancies, returns, and warranties

The Objectives of Supply

Good supply management aims to obtain:

17.The right part — conforming to original equipment manufacturer (OEM) specifications

18.The right quantity — neither too much (inventory costs) nor too little (stockouts)

19.At the right time — meeting delivery deadlines

20.At the right price — optimized total acquisition cost

21.At the right place — delivery to the correct service location

22.With the right quality — conforming to standards and requirements

These six "rights" constitute the fundamental principle of purchasing management. The Red Seal exam assesses your ability to apply this principle in practical situations.

The Purchasing Process

Step 1: Identifying the Need

Before any order, you must determine precisely:

The required part (part number, description, specifications)

The necessary quantity

The application (vehicle, equipment, machinery)

The urgency (normal order, rush order, backorder)

Common mistake: ordering without verifying the part number in the manufacturer's catalog. This leads to costly returns and additional delays.

Step 2: Supplier Selection

Supplier selection is based on several criteria:

Criterion	Typical Weighting	Example
Price	30%	Unit cost, volume discounts
Delivery time	25%	24 hrs, 48 hrs, 5 business days
Reliability	20%	On-time delivery rate
Quality	15%	Defective parts rate
After-sales service	10%	Return policy, technical support

You must also consider:

The supplier's geographic distance (shipping costs, lead times)

The supplier's storage capacity

The supplier's reputation and financial stability

Compliance with Canadian standards (e.g., CSA, ULC certified parts)

Step 3: Request for Quotation (RFQ)

A request for quotation (or call for tenders) is a formal document sent to multiple suppliers to obtain proposals. It must include:

The detailed description of the part

Estimated quantities

Required delivery times

Payment terms

The submission deadline

Rule of thumb: for purchases over $5,000, it is recommended to obtain at least three quotations to compare offers. For purchases over $25,000, a formal tendering process is often required by internal policies.

Step 4: Analyzing Offers

The comparative analysis of offers must consider the total acquisition cost, not just the unit price. This cost includes:

The purchase price

Shipping and handling charges

Customs duties (for imports)

Taxes (GST, PST)

Storage costs

Carrying costs (interest, insurance, obsolescence)

Total acquisition cost formula:

Total cost = Purchase price + Shipping + Duties + Taxes + Storage cost + Carrying cost

Step 5: Placing the Order

The purchase order (PO) is a contractual document that specifies:

The order number

The order date

The supplier (name, address, contact information)

The description of parts (number, quantity, unit price)

Delivery terms (date, location, shipping method)

Payment terms (e.g., 2/10, net 30)

Warranty terms

Note: the payment terms "2/10, net 30" mean a 2% discount is granted if payment is made within 10 days; otherwise, the full amount is due within 30 days.

Types of Orders

Normal Order

This is the standard order for parts in stock or parts ordered for a customer. The delivery time is the one agreed upon with the supplier.

Rush Order (Priority)

A rush order is processed as a priority by the supplier but generally incurs additional charges:

Expedited processing fees (often 10 to 25% of the amount)

Air freight or express courier charges

Special handling fees

Example: a part ordered urgently by courier may cost $85 in shipping for a $120 part. The total cost becomes $205, compared to $135 for a normal order.

Backorder

A backorder is an order that the supplier cannot fulfill immediately due to a lack of stock. The supplier commits to delivering as soon as the part becomes available. You must:

Confirm the expected delivery date

Inform the customer of the delay

Track the order until it is received

Standing Order (Blanket Contract)

A blanket contract is a long-term agreement with a supplier for recurring parts. It sets prices, terms, and lead times in advance, which reduces order processing time.

Receiving Goods

The Receiving Process

Upon receiving a delivery, you must:

90.Check the bill of lading (delivery slip) — compare it with the purchase order

91.Inspect the packaging — detect visible damage

92.Count the items — verify the quantities received

93.Verify part numbers — ensure the parts match the order

94.Inspect the condition of the parts — detect visible defects

95.Sign the delivery slip — noting any reservations (e.g., "received with damage")

96.Update inventory — record the receipt in the system

The Three-Way Check Rule

Before accepting a delivery, you must compare three documents:

Document	Source	Role
Purchase order	Buyer	Defines what was ordered
Bill of lading	Carrier	Describes what was shipped
Invoice	Supplier	Requests payment for what is delivered

If the three documents do not match, you must refuse the delivery or receive it with reservation and document the discrepancies.

Delivery Discrepancies

Possible discrepancies include:

Excess quantity — more parts than ordered

Short quantity — fewer parts than ordered

Incorrect part — wrong part number

Damaged part — visible or hidden damage

Late delivery — later than the agreed-upon date

For each discrepancy, you must:

109.Document the discrepancy in writing (receiving form, internal note)

110.Photograph the damage if possible

111.Notify the supplier as soon as possible (generally within 24 to 48 hours)

112.Negotiate a solution (replacement, credit, return)

Quality Control

Receiving Inspection

Receiving inspection can be:

Total (100%) — every part is checked (for critical or expensive parts)

Sampling — only a portion of the lot is checked (for standard parts)

The ISO 2859-1 standard (Sampling procedures for inspection by attributes) is often used to determine sample size and acceptance criteria.

Quality Levels

Level	Defect	Example
Critical	Safety hazard	Defective brake
Major	Makes the part unusable	Seized bearing
Minor	Does not affect function	Cosmetic scratch

Certificates of Conformity

Certain parts must be accompanied by documents attesting to their compliance:

Certificate of Conformity (CoC) — attests that the part meets specifications

Certificate of Analysis (CoA) — for fluids, greases, chemicals

Calibration certificate — for measuring instruments

Managing Returns

Reasons for Returns

Returns can be motivated by:

Defective part (manufacturing defect)

Incorrect part (wrong number ordered or delivered)

Damaged part (shipping or handling)

Excess inventory (over-ordering)

Customer order cancellation

The Return Process

137.Obtain a Return Goods Authorization (RGA) number from the supplier

138.Prepare the part — original packaging, labeling

139.Include the documentation — copy of the invoice, RGA number, reason for return

140.Ship the part — according to the supplier's instructions (designated carrier, address)

141.Track the credit — verify that the credit or replacement is issued

Caution: without a return authorization, the supplier may refuse the goods or apply restocking fees (often 15 to 25%).

Return Timeframes

Return timeframes vary by supplier:

Type of Part	Typical Timeframe
Standard part	30 to 90 days
Electrical part	15 to 30 days
Special part (made to order)	Non-returnable
Opened part (used)	Non-returnable

Warranties

Types of Warranties

Manufacturer's warranty — covers defects in materials and workmanship

Supplier's warranty — extends or supplements the manufacturer's warranty

Statutory warranty — provided by law (e.g., implied warranty of acceptable quality)

Extended warranty — sold separately to the customer

Warranty Conditions

For a warranty to be valid, you must:

Follow the installation and usage conditions

Keep the proof of purchase (invoice)

Use the part for its intended application

Not modify the part

Processing Warranty Claims

160.Verify validity — purchase date, conditions

161.Document the failure — photos, description, usage conditions

162.Retrieve the defective part — return it to the supplier

163.Issue a credit or replacement — according to policy

164.Follow up on the file — until resolution

Supplier Relations

Supplier Management

A good supplier relationship is based on:

Communication — promptly informing of problems

Transparency — sharing demand forecasts

Reliability — honoring commitments (payments, orders)

Collaboration — working together to improve quality and reduce costs

Supplier Evaluation

Periodic supplier evaluation allows you to:

Measure performance (lead times, quality, price)

Identify recurring problems

Negotiate improvements

Decide whether to continue or end the relationship

Key Performance Indicators (KPIs):

Indicator	Formula	Typical Target
On-time delivery rate	(On-time deliveries ÷ Total deliveries) × 100	≥ 95%
Defective parts rate	(Defective parts ÷ Parts received) × 100	≤ 1%
Return rate	(Returns ÷ Orders) × 100	≤ 2%
Average delivery time	Sum of lead times ÷ Number of orders	Per contract

Legal and Regulatory Aspects

Applicable Canadian Standards

Although this chapter does not cover electrical standards, you must be aware of the general standards applicable to parts:

CSA Group — standards for many products (e.g., CSA B149.1 for natural gas and propane appliances)

ULC (Underwriters Laboratories of Canada) — safety standards

Canadian Electrical Code, Part I (CE Code) — for electrical parts (Rule 8-200 for conductors)

Rule 8-200 of the Canadian Electrical Code, Part I: it specifies requirements for conductors and cables, including minimum sizes based on ampacity.

Customs Duties and Importation

For imported parts, you must consider:

The customs tariff — rate based on country of origin and type of part

The Canadian Free Trade Agreement (CFTA) — for interprovincial trade

The CUSMA (Canada–United States–Mexico Agreement) — for North American parts

The customs declaration — form required for imports

Intellectual Property and Counterfeit Parts

Counterfeit parts are a growing problem. You must:

Verify the authenticity of parts (serial numbers, holograms, packaging)

Purchase from authorized suppliers

Report any suspicion of counterfeiting to the authorities

Supply Calculations

Calculating Unit Cost

When buying in bulk, the unit cost can be reduced. Example:

Price for 10 parts: $450

Price for 50 parts: $2,000 (10% savings)

Unit cost (10 parts) = $450 ÷ 10 = $45.00

Unit cost (50 parts) = $2,000 ÷ 50 = $40.00

Savings per part = $45.00 − $40.00 = $5.00

Total savings = $5.00 × 50 = $250.00

Calculating Discounts

Single discount: Price × (1 − Discount rate)

Example: part at $120 with a 15% discount

$120 × (1 − 0.15) = $120 × 0.85 = $102.00

Chain discount: applied successively

Example: $120 with discounts of 10% and 5%

$120 × 0.90 = $108.00

$108 × 0.95 = $102.60

Note: a chain discount is not equivalent to a single 15% discount ($102.60 ≠ $102.00).

Calculating the Reorder Point

The reorder point is the stock level that triggers a new order.

Reorder point = (Daily demand × Lead time) + Safety stock

Example:

Daily demand: 5 parts/day

Lead time: 4 days

Safety stock: 10 parts

Reorder point = (5 × 4) + 10 = 30 parts

Calculating the Economic Order Quantity (EOQ)

The economic order quantity minimizes the total inventory management cost.

EOQ = √(2 × Annual demand × Ordering cost ÷ Unit holding cost)

Example:

Annual demand: 1,200 parts

Ordering cost: $50 per order

Holding cost: $3 per part per year

EOQ = √(2 × 1,200 × 50 ÷ 3) = √(120,000 ÷ 3) = √40,000 = 200 parts

Pitfalls to Avoid

237.Confusing unit price and total cost — shipping, taxes, and storage costs can make an apparently cheaper offer actually more expensive.

238.Not verifying the part number upon receipt — a visually identical part may have a different number and may not be suitable.

239.Accepting a delivery without inspection — once the delivery slip is signed without reservation, it is difficult to claim for damages.

240.Returning a part without a Return Goods Authorization (RGA) — the supplier may refuse the return or impose fees.

241.Ignoring warranty timeframes — a late claim may be refused.

242.Calculating a chain discount as a single discount — the results differ.

243.Forgetting safety stock in the reorder point calculation — this leads to stockouts.

244.Ordering without checking existing stock — this creates surpluses and obsolescence.

245.Not documenting delivery discrepancies — without written proof, a claim is difficult.

246.Confusing manufacturer's warranty and supplier's warranty — the conditions and durations differ.

Exam Tips

Read each question carefully — Red Seal exams often use scenarios with important details.

Identify which "right" is involved — right part, right quantity, right time, right price, right place, right quality.

Use the provided formulas — EOQ and reorder point calculations are common.

Memorize typical timeframes — 30 to 90 days for standard returns, 24 to 48 hours to report a discrepancy.

Know the payment terms — 2/10, net 30 is a classic.

Pay attention to units — calculations can be in days, weeks, or months.

Summary

Supply aims to obtain the right part, in the right quantity, at the right time, at the right price, at the right place, and with the right quality.

The purchasing process includes: identifying the need, selecting the supplier, requesting quotations, analyzing offers, and placing the order.

The total acquisition cost includes price, shipping, duties, taxes, and storage costs.

Receiving requires verifying the bill of lading, inspecting parts, and comparing with the purchase order.

Discrepancies must be documented and reported within 24 to 48 hours.

Returns require a Return Goods Authorization (RGA) and must respect variable timeframes.

Warranties cover defects in materials and workmanship, subject to conditions.

Supplier relationships are based on communication, transparency, and reliability.

Key calculations are: unit cost, discounts, reorder point, and economic order quantity.

Canadian standards (CSA, ULC, Canadian Electrical Code) apply to certain parts.

Pitfalls to Avoid (Reminder)

Pitfall	Consequence	Prevention
Confusing unit price and total cost	Hidden surcharges	Calculate the total acquisition cost
Not verifying the part number	Returns and delays	Check systematically upon receipt
Signing without inspection	Loss of recourse	Inspect before signing
Returning without RGA	Refusal or fees	Obtain authorization before shipping
Ignoring warranty timeframes	Claim refused	Track deadlines
Chain discount miscalculated	Pricing error	Calculate step by step
Forgetting safety stock	Stockouts	Include safety stock in the calculation
Ordering without checking stock	Surplus and obsolescence	Check stock before ordering
Not documenting discrepancies	Claim impossible	Document immediately
Confusing warranties	Inadequate coverage	Know the conditions of each warranty
