FIFO Costing System

Overview

FIFO (First-In, First-Out) is an inventory costing method that ensures your oldest stock is used first when making sales. GSK POS implements FIFO automatically, giving you accurate cost tracking and profit calculations without any manual work.

💡 Powerful Feature: While most businesses track this manually in notebooks, GSK POS does it automatically for every single transaction!

What is FIFO?

FIFO stands for "First-In, First-Out" - it means the first products you buy (first in) are the first ones you sell (first out).

Real-World Example

📦 Imagine Your Store Shelf

Monday: You buy 10 bottles of juice at UGX 2,000 each

Wednesday: You buy 10 more bottles at UGX 2,200 each (price increased)

Friday: Customer buys 5 bottles

Question: Which bottles did the customer get? What did they cost you?

FIFO Answer: Customer got bottles from Monday's purchase (first in), so your cost was UGX 2,000 each, not UGX 2,200!

Why FIFO Matters

💰 Accurate Profit Calculation

If you sell at UGX 3,000:

With FIFO: Profit = 3,000 - 2,000 = 1,000 per bottle ✅ (Correct!)
Without FIFO: Might use wrong cost = Wrong profit ❌

Multiply this by thousands of transactions - accuracy matters!

📊 Better Business Decisions

Know real profits: Not guesses or estimates
Price correctly: Based on actual costs
Track trends: See how costs change over time
Tax accuracy: Correct cost of goods sold for taxes

🔄 Natural Inventory Flow

Use old stock first: Prevents expiry and waste
Fresh products: Customers get newer stock
Better inventory management: Natural rotation

How GSK POS Implements FIFO

GSK POS handles FIFO completely automatically. You don't need to do anything - it just works!

What Happens Behind the Scenes

You Buy Stock

When you purchase products, GSK POS records:

Product name and quantity
Purchase price
Purchase date and time
How much stock remains from this purchase

You Make a Sale

GSK POS automatically:

Looks at all your purchase lots for this product
Uses stock from the oldest purchase first
Calculates cost based on that purchase price
Updates remaining quantity for that lot

Tracks Usage

System keeps detailed records:

Which purchase lot was used for each sale
How much from each lot
What the cost was
How much is left in each lot

Calculates Profit

For each sale, you get accurate profit:

Sale price - Actual purchase cost = Real profit
No guessing, no averaging (unless needed)
All tracked automatically

Weighted Average Cost

When a single sale uses stock from multiple purchase lots, GSK POS calculates a weighted average cost:

📐 Example: Mixed Lots

Your Stock:

Lot 1 (Monday): 3 bottles left at UGX 2,000 each
Lot 2 (Wednesday): 10 bottles at UGX 2,200 each

Customer Orders: 5 bottles

FIFO Logic:

Use all 3 bottles from Lot 1 (oldest first)
Use 2 bottles from Lot 2

Cost Calculation:

3 bottles × 2,000 = 6,000
2 bottles × 2,200 = 4,400
Total cost: 10,400
Average cost per bottle: 10,400 ÷ 5 = 2,080

Result: System records UGX 2,080 as the cost for this sale

Real-World Scenarios

Scenario 1: Price Increases

📈 Rising Costs

Situation: Sugar prices keep increasing

Your Purchases:

January: 100 kg at 3,000 per kg
February: 100 kg at 3,500 per kg
March: 100 kg at 4,000 per kg

FIFO Benefit:

Early sales use January stock (3,000 cost) = Higher profit
Later sales use March stock (4,000 cost) = Lower profit
You see exactly when profits decreased
Can adjust prices accordingly

Scenario 2: Bulk Purchases

🎯 Discount Opportunity

Situation: Supplier offers bulk discount

What You Do:

Buy 1000 units at discounted price
Normal price: 1,000 per unit
Bulk price: 800 per unit (20% off)

FIFO Advantage:

System uses bulk purchase cost (800) for sales
You enjoy higher profit margin on every sale
Can see how much extra profit bulk buying generated
Make informed decisions about bulk buying
