Before comparing totals, move quote lines to a shared form: product code and configuration, delivery point, freight, accessories, packaging and partial-delivery terms. Leave excluded or unspecified fields visibly blank.

Separate initial consumables from items needed for later use. Confirm in writing whether a part is needed on each shipment, its replacement condition and manufacturer code; do not add an unverified service life or savings figure.

Take date, currency, tax, warranty and service scope from the quotation. Request written confirmation of delivery window and stock status; do not call an offer cheaper until scope matches.
