A shortage before the Friday shipment
Use one realistic scenario to connect the forecast, inventory, supplier limit, line capacity and customer promise. Pick a response to reveal the trade-offs.
DEMAND TO COVER120 forecast + 8 backlog128 bottles in total
AVAILABLE SUPPLY28 stock + 20 receipts48 already cover demand
NET BUILD NEED80 bottles128 − 48 = 80
Main supplier72 kits
→Normal line76 units
→Dispatch cap82 units
Supplier is the first constraintWhat would you do?
Assumptions: alternate kits cost ₹35 each above base, overtime costs ₹90 per extra unit, and dispatch can handle 82 units. These are made-up teaching figures, not market prices. Whether the premium is worthwhile depends on the cost of a missed order and available policy.
Learning exercise: the quantities are illustrative. A real plan also depends on product rules, calendars, data quality, supplier agreements and local operating constraints.

FINANCE + SUPPLY-CHAIN PLANNING
EDUCATIONAL TOOLFBS — A New Forecasting Tool
A learning tool that connects a supply-chain inventory forecast with a transparent next-year balance-sheet scenario.
Your files stay in this browser. PDFs are read on your device and are not uploaded to Supply Chain Ideas. Use fictional or authorized data. This is an educational estimate, not accounting, investment or lending advice.
A NEW WAY TO EXPLORE FINANCE + OPERATIONS
See how an inventory plan can change the balance-sheet conversation.
Businesses often plan demand and inventory separately from financial forecasts. FBS brings those inputs into one educational scenario so learners can see the connection, review assumptions and ask better planning questions.
Compare five years of balance-sheet history with a reviewed next-year inventory figure.
Review extracted values, line-by-line methods, the balance check and a downloadable report.
Use the result to discuss working capital and planning assumptions; it is not a cash-flow forecast or financial advice.

What happens to my PDFs?
The PDFs and extracted text stay in your browser session. The tool does not send them to a server or save them to an account. Closing or refreshing the tab clears the selected files and extracted values. Avoid uploading confidential records to any website unless you have permission.
Check every extracted figure
PDF layouts differ. Values are suggestions only; compare them with each statement and edit any missing or incorrect amount. Enter figures in the same unit.
Document order: oldest year in the first PDF, newest year in the fifth. The year labels are editable. Blank values are treated as missing, not zero.
Enter or verify the historic values to check each year’s balance.

Forecast method and limitations
A TRANSPARENT FIRST MODEL
From inventory decisions to financial visibility.
The model projects non-cash balance-sheet lines using the median annual change in the reviewed history. It uses the supplied next-year inventory estimate, then calculates cash as a balancing residual so the accounting identity is visible. That residual is not a cash-flow forecast.

HOW TO READ THESE NOTES
The 300 articles are original educational briefs, not copied abstracts or claims that any single AI method will improve every supply chain. They translate broad research themes into practitioner questions and small experiments.

FORECASTING PLAYGROUND
Change the demand shape.
Adjust trend, seasonal swing and noise. See how a simple baseline compares with a small AI-style model on held-out weeks.
Read the calculator guides →Illustrative only · The “AI-style” forecast is a local regression model with a trend and seasonal terms. It is not an LLM, does not upload data, and is not a production forecast.

Try the numbers in your browser. These tools use transparent starter formulas, not a full planning system.
Score a forecast
Compare actual and forecast demand, in matching time periods and units.
MAE is in units; WAPE shows total absolute error relative to total actual demand; signed bias is forecast minus actual. WAPE is undefined when total actual demand is zero.Reorder point & suggested order
A basic continuous-review example: expected lead-time demand plus a chosen buffer.
Reorder point = average demand × lead time + buffer. Suggested order restores inventory position to that point; lot sizes and calendars are not modeled.Check a line load
Estimate required run and setup minutes against the time actually available.
Includes one setup allowance and one item rate. Real schedules may need multiple routings, shifts, labor rules, downtime and sequence-dependent setup.Educational only. Validate formulas, units, policy settings and service targets with your planning team before using them for operational decisions.
Good yardstick, slow to turn.
A moving average is transparent and hard to overfit. It can lag after a trend shift, flatten peaks, and miss recurring seasonal peaks.
Can fit a pattern that vanished.
A trend plus seasonal model can be wrong after a regime change, with short or biased history, or when promotions and supply constraints reshape observed sales.
Model names are descriptive of this demonstration. Compare on rolling, time-ordered holdouts before selecting any method for real planning.
