Stubs

Each stub is a tear-off line. Quantity, rate, amount, tax. Nothing collapsed.

A stub is the atomic document. Statements are lists of stubs. Books are lists of statements.

Fields

type Stub = {
  code: string;
  quantity: number;
  unit: string;
  rate: number;
  amount: number;
  tax?: number;
};

amount must equal quantity * rate after the printed rounding rule. If it does not, the close fails.

You may void a draft stub. After close, you print a credit stub. You do not edit the original.
