Separate equipment cost from the cost to put it to work
Use three totals: the agreed equipment, delivery-related items, and site work/services. Keep unpriced buyer obligations visible instead of treating them as zero. A lower machine subtotal can coexist with a larger remaining interface or installation scope.
- Record currency, quotation date and validity as stated by the supplier.
- Distinguish priced options from included items.
- List unknown costs as not quoted, with an owner for clarification.
