Appointment and scope
Which products, which territory, which customer segments, and whether the appointment is exclusive or non-exclusive. Vague scope is the root of most channel conflict, because two partners can each read a loose description as covering the same account.
Pricing and discount schedule
The transfer price or discount off list, any volume tiers, and whether the reseller sets its own resale price or works from a recommended one. Rules on controlling resale prices vary by jurisdiction, which is a specific point worth taking advice on.
Minimum commitments
A volume, revenue, or certification level the reseller must achieve to keep privileged terms. This is the clause that gives exclusivity teeth. Without it, exclusivity is a gift.
Trademark and intellectual property
A limited licence to use your name, logo, and materials for the purpose of selling the product, with clear limits and a defined end when the agreement terminates.
Support and service obligations
Who is first line, what the reseller must resolve itself, what escalates, and what the vendor commits to in response. Unclear support ownership always resolves into calls reaching the vendor, whatever the contract implies.
Data protection
Where the reseller handles end customer personal data, the roles and responsibilities of each party should be named rather than left to inference.
Term, renewal, and termination
Including the awkward case: what happens to existing end customers when the relationship ends, whether contracts transfer, how prepaid amounts are handled, and what materials must be returned or stopped.
