💰Finance & Money Fundamentals15 Topics
1. Revenue vs Profit vs Cash Flow

Revenue is money generated from sales. Profit is what remains after relevant costs and expenses, while cash flow tracks actual cash moving into and out of the business.

2. Gross Profit vs Net Profit

Gross profit is sales minus direct costs. Net profit is the amount left after operating expenses, interest, taxes and other applicable costs.

3. Fixed Cost vs Variable Cost

Fixed costs generally stay stable within a relevant activity range, while variable costs change with output or sales volume.

4. Contribution Margin

Contribution margin is sales minus variable costs. It shows how much is available to cover fixed costs and then contribute to profit.

5. Break-Even Point

Break-even is the level where total revenue equals total costs. The business has neither profit nor loss at this point.

6. Working Capital

Working capital concerns short-term operating resources and obligations. It is important for funding day-to-day business activity.

7. Cash Conversion Cycle

The cash conversion cycle measures how long cash is tied up between paying suppliers and collecting customer cash. Shorter cycles generally support liquidity.

8. Accounts Receivable

Accounts receivable is money customers owe for credit sales. Strong collection processes can improve cash availability.

9. Accounts Payable

Accounts payable is money owed to suppliers. Payment planning helps protect cash while maintaining supplier relationships.

10. Operating Expenses

Operating expenses are costs required to run the business outside direct production costs, such as administration, selling and office expenses.

11. EBITDA Basics

EBITDA means earnings before interest, taxes, depreciation and amortization. It is an operating indicator, not the same as cash flow or net profit.

12. Profit Margin

Profit margin expresses profit as a percentage of revenue. It helps compare profitability across products, periods or businesses.

13. Cash Flow Management

Cash flow management means forecasting, monitoring and controlling cash inflows and outflows so obligations can be met on time.

14. Budgeting Basics

A budget estimates expected income, expenses, investment and cash needs. Comparing actual results with budget reveals important variances.

15. Financial Ratios

Financial ratios convert financial figures into useful indicators such as liquidity, profitability, efficiency and leverage.

📉Cost Reduction & Cost Control15 Topics
1. Cost Reduction vs Cost Cutting

Cost reduction seeks sustainable efficiency improvements. Cost cutting may simply reduce spending and can create quality, capacity or service problems if poorly planned.

2. Manufacturing Cost

Manufacturing cost covers resources consumed to make a product, including material, direct labour and manufacturing overhead.

3. Material Cost

Material cost is the cost of production inputs. Purchasing, yield improvement, design optimization and scrap reduction can influence it.

Scrap is material or product that cannot be used as intended. Reducing scrap improves yield and lowers production losses.

9. Rejection Cost

Rejection cost is the economic impact of products failing requirements, including material, labour, inspection, disposal and customer-related effects.

10. Rework Cost

Rework means correcting a product or process before acceptance. Tracking rework exposes process weaknesses and repeated quality losses.

11. Downtime Cost

Downtime cost is the business impact of stoppages, including lost output, idle resources, delivery delays and recovery expenses.

12. Inventory Carrying Cost

Carrying cost is the cost of holding inventory, including storage, handling, financing, insurance, damage and obsolescence.

13. Transportation Cost

Transportation cost covers movement of materials and products. Route planning, load utilization and shipment consolidation can reduce it.

14. Procurement Cost

Procurement cost can include purchase price plus ordering, inspection, logistics and administration. Total cost is more useful than price alone.

15. Cost Saving Ideas

Good cost-saving ideas target measurable waste or inefficiency, such as energy losses, scrap, excess inventory, repeated failures and unnecessary processing.

📦Inventory Management17 Topics
1. What is Inventory?

Inventory is stock held for production, sale or operational use. Common categories are raw material, WIP and finished goods.

2. Raw Material

Raw material is input stock used to manufacture products. Availability must be balanced against holding cost and supply risk.

3. WIP

Work-in-process is material that has entered production but is not finished. Excess WIP can hide bottlenecks and increase lead time.

4. Finished Goods

Finished goods are completed products ready for sale or dispatch. Stock levels should reflect demand and service requirements.

5. Safety Stock

Safety stock is extra inventory kept to protect against uncertainty in demand or supply. Its level should reflect business risk.

6. Reorder Level

Reorder level is a trigger for replenishment. It is normally linked to expected usage during lead time and a suitable safety allowance.

7. Economic Order Quantity

EOQ is a classical inventory model used to estimate an order quantity that balances ordering and holding costs under stated assumptions.
