However, some suppliers may see this as an invitation to take exception to your terms as part of their proposal. How can you avoid this becoming a mess?
Just build in degree of acceptance of your terms and conditions as one of the criteria for award, right alongside price, lead time, etc. If you use a “risk” criterion as part of a weighted average supplier scorecard in ranking suppliers, acceptance of your terms and conditions could be factored into that risk score.
Let’s face it. Negotiating terms and conditions rather than using your standard terms takes time, costs your organization money, and can expose your organization to more risk. The more willing a supplier is to work with your standard terms and conditions, the more favorably evaluated they should be.
