Lesson Content/Board Summary

Modern Trend in Retailing

Branding

Branding is the process of giving a product a unique name, design, symbol, or packaging so that buyers can identify it easily and distinguish it from other products.

The following are advantages of branding:

Easy identification of products by customers.
Helps to build customer loyalty and repeat purchase.
Helps producers and retailers to promote products easily.
Improves product image and can increase sales.
Reduces confusion between similar goods.

The following are disadvantages of branding:

High cost of packaging, advertising, and promotion.
Branded goods may be more expensive for customers.
Imitation and fake products can damage the brand image.
Some customers may buy based on name rather than quality.

Self-service

Self-service is a retail method where customers select goods by themselves from shelves or displays and pay at a checkout counter.

The following are advantages of self-service:

Saves time for customers who can pick items quickly.
Allows customers to compare products and prices easily.
Reduces the need for many sales attendants.
Encourages impulse buying, which can increase sales.

The following are disadvantages of self-service:

High risk of shoplifting and pilferage.
Customers may damage goods while handling them.
Not suitable for very expensive or delicate goods without supervision.
Some customers may need assistance and may feel confused.

After-sales Services

After-sales services are services provided to customers after they have purchased goods to ensure satisfaction and continued patronage.

The following are examples of after-sales services:

Warranty and guarantee support.
Free installation of products.
Repairs and maintenance.
Customer support and complaint handling.
Spare parts supply.

The following are advantages of after-sales services:

Builds customer trust and confidence in the seller.
Encourages repeat purchase and customer loyalty.
Reduces product returns and customer complaints.
Improves the reputation of the business.

The following are disadvantages of after-sales services:

Increases business costs due to staffing and service tools.
Time-consuming to handle repairs, complaints, and follow-up.
May lead to losses if services are abused by customers.
Requires skilled personnel and good service organization.
