Internal Trade

What is internal trade?

Internal trade (home trade) is buying and selling of goods and services within the borders of one country. Payment is in the home currency and there is no customs duty. It has two parts:

• Wholesale trade: buying in large amounts from producers and selling to retailers or big users for resale.
• Retail trade: buying from wholesalers or producers and selling in small amounts to the final consumer.

Services of wholesalers

To manufacturers

• Large-scale production: bulk orders let factories make more at lower cost.
• Bearing risk: of price fall, theft, damage while goods are with them.
• Financial help: pay cash quickly or in advance.
• Expert advice and market news: what customers want, prices of rivals.
• Help in marketing: reach many retailers so the producer need not.
• Storage: keep goods in warehouses until they are needed.

To retailers

• Availability: goods of many producers in one place.
• Small lots: retailers need not buy huge stock.
• Credit: goods now, pay later.
• Marketing help: ads, new product information.
• Specialised knowledge and sharing risk of big stock.

Services of retailers

To producers and wholesalers

• Distribution: takes goods to many scattered buyers.
• Personal selling: explains and persuades customers.
• Large-scale operations possible for producers and wholesalers.
• Market information: tells what customers like and dislike.
• Promotion: displays and local ads.

To consumers

• Regular availability near home.
• Information on new products and features.
• Convenience: small quantities, suitable hours.
• Wide choice of brands.
• After-sale service, home delivery and sometimes credit.

Small retailers: itinerant and small fixed shops

Itinerant retailers (no fixed place)

• Peddlers and hawkers: carry goods on foot, cycle, cart or head, selling at the door.
• Market traders: sell at weekly haats or fairs on fixed days.
• Street traders (pavement vendors): sell at busy spots like bus stands.
• Cheap-jacks: take a small shop in an area for a short time, then move.

Small fixed-shop retailers

• General stores: daily needs near homes (grocery, toiletries).
• Single-line stores: one line of goods, like shoes or books.
• Speciality stores: one type of product in depth, like baby wear.
• Street stalls: small stalls at busy corners.
• Second-hand goods shops: used books, furniture, clothes.

Large retailers: department stores, chain stores, mail order

Department store

A large store with many departments under one roof and one management, each selling a different kind of goods. Merits: one-stop shopping, attractive services, central location. Limits: high costs so prices may be higher; less personal attention.

Chain stores (multiple shops)

A network of similar shops owned by one company in different areas, selling the same standard goods at the same prices, with central buying. Merits: low cost from bulk buying, spread of risk, same quality everywhere. Limits: limited range of goods, little freedom for shop managers, less personal service.

Mail order houses

Sell through ads, catalogues or letters, take orders by post, and send goods by post, often by VPP / cash on delivery. No shop, so low cost and wide reach. Limits: buyer cannot see goods first, no personal contact, delay in delivery. Online shopping is its modern form.

Department store vs chain store

• Location: one central place vs many places near buyers.
• Range: almost everything vs a limited line.
• Prices: may vary vs the same everywhere.
• Credit: may give credit vs mostly cash.

Goods and Services Tax (GST)

GST is a single, destination-based tax on the supply of goods and services, started in India on 1 July 2017. It replaced many older indirect taxes (like excise duty, service tax and VAT), giving "one nation, one tax".

Parts of GST

• CGST (Central GST) and SGST/UTGST (State or Union Territory GST): charged in equal halves when the sale is inside one state.
• IGST (Integrated GST): charged by the Centre when goods move from one state to another; it is later shared with the consuming state.

Input tax credit

At each stage a seller pays GST only on the value it adds, because it gets credit for the GST already paid on its purchases. So there is no "tax on tax" (cascading effect).

Other points

• The GST Council (Union and State finance ministers) decides rates.
• Rates are in slabs; since September 2025 the main slabs are 5% and 18%, with 40% on luxury and sin goods and many basic items at 0%.
• Businesses above a turnover limit must register and get a GSTIN; returns are filed online.

Benefits

A common national market, less tax evasion because of online records, easier movement of goods across states (no check-posts), and lower cost for traders through input tax credit.

Key formulas and definitions

• Internal trade = Wholesale trade + Retail trade (no customs duty)
• Chain: Producer → Wholesaler → Retailer → Consumer
• Intra-state sale: GST = CGST + SGST (half each)
• Inter-state sale: GST = IGST (full rate)
• Tax payable at a stage = GST on sale − input tax credit on purchase

Worked examples

Common mistakes

• Saying internal trade pays customs duty. Customs is only in foreign trade.
• Calling a chain store a department store. Chain = many look-alike shops in many places; department store = one big store with many departments.
• Charging CGST + SGST on an inter-state sale. Between states, IGST is charged.
• Thinking GST is paid on the full price at every stage. Input tax credit means each seller pays only on the value added.
