Supplier offer comparison

Compare supplier offer lines against required items, review AI match proposals and inspect quantity, currency, shipping and total-price differences.

Input

Ten blue A4 folders are required. Two suppliers quote the same quantity at 2.50 and 2.30 EUR per piece, with line shipping of 5.00 and 8.00 EUR.

Result

After the proposed product matches are reviewed, line totals are 30.00 EUR and 31.00 EUR. The lower unit price is not the lower total.

Different product wording makes quotations difficult to compare. AI proposes which offer lines correspond to required items; exact arithmetic then shows which quotes are comparable and where information differs.
