Ask each wholesaler to quote the same product code, specification, quantity, pack size, and delivery point. Record the date and validity of each quote, and separate confirmed charges from estimates for transport, taxes, or other fees.

Compare the total cost for the quantity your shop needs, not just the unit price. Include minimum order, payment timing, delivery, replacement terms, and differences in grade or packaging. If quotations describe different products, get clarification before comparing the numbers.

A low amount may exclude costs or depend on terms you cannot use. Keep the offers and your comparison together, and confirm the final specification and amount before ordering. Do not present a provisional supplier quote as a price you can guarantee customers. Check whether the quote uses the same currency and tax basis.
