This can be a solid approach. I would recommend that the reseller and platform provider get similar deals, to keep consistency.

There are many platforms out that there allow for affiliated links and vendors that can sell your software as well, I suggest you take a look at this as an option as well.

Ensure that you have a reasonable profit margin as part of the incentive process as there could be additional time commitments, extra costs, etc. that come up as part of implementation.
