Questions

What input does this workflow need?

CSV lines {id,item,quantity,unitCents,actualCents}, or JSON {currency,lines:[...]}. Quantities are whole units and amounts are integer cents.

What does it calculate or validate?

Calculate quantity × unit cost, total planned and actual cost, and remaining amount. Apply valid edits atomically; reject negatives, fractions and overflow without corrupting the last valid state.

What is outside its scope?

No formulas, fractional quantities, multiple currencies or shared editing; export your changes before closing.

Can I use it without an API key?

Yes. The local template, validation and exports work without a key. PopNow media is optional and requires a quoted, approved API USD budget.
