Lesson Content/Board Summary

BUSINESS DOCUMENTS

Essential Business Documents Used in Buying and Selling

Business documents are written records that provide evidence of transactions and agreements between parties. They are vital for clarity, accountability, and legal validity in buying and selling processes.

Some essential business documents include:

  1. Letter of Inquiry: A formal letter from a potential buyer to a seller, requesting information about goods, services, prices, or terms of sale. It initiates the buying process.
  2. Quotation: A document issued by a seller in response to an inquiry, stating the price, terms, and conditions for specific goods or services. It is an offer to sell.
  3. Catalogue: A comprehensive list or booklet containing detailed descriptions, prices, and images of products offered by a seller. It helps buyers make informed choices.
  4. Order: A formal request from a buyer to a seller to supply specific goods or services. It signifies the buyer’s intention to purchase.
  5. Invoice: A commercial document issued by a seller to a buyer, detailing the goods or services provided, their quantities, agreed prices, and the total amount due. It is a demand for payment.
  6. Receipt: A written acknowledgment from the seller to the buyer that payment has been received for goods or services. It serves as proof of payment.
  7. Delivery Note: A document that accompanies goods during delivery, listing the items being delivered. The buyer signs it to confirm receipt of the goods.
  8. Statement of Account: A periodic summary sent by a seller to a buyer, showing all transactions (invoices, payments, credit notes, debit notes) over a specific period and the outstanding balance.
  9. Debit Note: A document issued by a seller to a buyer to correct an undercharge on an invoice or to charge for additional items/services not originally billed. It increases the amount owed by the buyer.
  10. Credit Note: A document issued by a seller to a buyer to correct an overcharge on an invoice, grant a refund, or acknowledge returned goods. It reduces the amount owed by the buyer.

Trade Terms and Abbreviations

Trade terms are standardized abbreviations used in commercial contracts to define the responsibilities of the buyer and seller regarding the shipment of goods, including costs, risks, and insurance.

Common trade terms and their meanings:

  1. FOB (Free On Board): The seller is responsible for delivering the goods to the named port of shipment and loading them onto the vessel. The buyer assumes all risks and costs once the goods are on board the ship.
  2. FOR (Free On Rail): Similar to FOB, but the seller’s responsibility ends when the goods are loaded onto the railway wagon at the named railway station.
  3. CWO (Cash With Order): The buyer must pay for the goods in full at the time of placing the order. The seller will only dispatch the goods after receiving payment.
  4. EXSHIP (Ex-Ship): The seller is responsible for delivering the goods to the named port of destination, and the buyer takes delivery from the ship. The seller bears the cost and risk until the goods are available for unloading at the destination port.
  5. COD (Cash On Delivery): The buyer pays for the goods at the time of delivery. The seller ships the goods, and payment is collected upon their arrival.
  6. CIF (Cost, Insurance, and Freight): The seller pays for the cost of goods, insurance, and freight to bring the goods to the named port of destination. Risk transfers to the buyer once the goods are loaded onto the vessel at the port of shipment.
  7. FAS (Free Alongside Ship): The seller is responsible for delivering the goods alongside the vessel at the named port of shipment. The buyer then assumes all costs and risks from that point, including loading the goods onto the ship.
