PO Line Snap

Proof purchase-order and invoice line totals locally from the Chrome toolbar.

PO Line Snap gives you fast line-total math for purchase orders, invoices, quotes, and order checks. Use it to verify one line before sending, approving, reconciling, or pasting totals into a spreadsheet. Enter quantity, unit cost, discount, tax, freight or fee adders, and an expected total. PO Line Snap shows the gross amount, discount, net amount, tax, adders, final total, landed unit cost, and variance. Features: - Calculate quantity times unit cost. - Support percent discounts and fixed discount amounts. - Add tax, freight, fees, credits, or other adjustments. - Compare the calculated total against an expected total. - Show landed unit cost. - Copy a concise proof note or just the final total. - Handles pasted numbers with currency symbols and commas. - Runs locally with no account, no backend, no network calls, and no requested Chrome permissions. PO Line Snap is a line-total math helper. It is not accounting, tax, purchasing, ERP, invoicing, or compliance software. Always verify the source document, supplier terms, tax rules, and approval requirements that apply to your work.
