Quote against one revision
Send the same identified bottle, component, material, artwork and packing brief to each candidate. Check substitutions, exclusions and quantity bases in their responses. A lower figure may reflect a different scope, so clarify the comparison before deciding.
Use samples to answer priority questions
Use a comparison sheet for appearance, assembly, function, supporting evidence and open issues. Distinguish display, development and approved samples. Check the scope and identity of any third-party report instead of assuming a showroom example represents your order.
Ask about repeat orders and changes
Clarify how repeat orders identify revisions, how substitutions are communicated and how issues are retained and resolved. Include the clarity of communication in your assessment. An attractive photograph cannot establish delivery, quality and commercial performance.
