What it does
Every number on an invoice rechecked, so you pay or send the right amount. Paste the invoice text, a table or a CSV. The skill pulls out each line, the discounts, the tax and the stated totals. Then it recomputes them, using a small Python script if it can run one, and compares the results with what the invoice says. Every difference is shown as a table with both figures. It then checks which standard fields are present, such as supplier, customer, number, dates and payment terms, and flags oddities like a due date before the invoice date or mixed currencies. It never gives tax advice or changes the invoice quietly.
