Approvals - If you are selling 1-2 zips at the pricing shown in SHERPA pricing tool, you don't need approval.

You can sell 1-2 zips at "retail" at any time. "Retail" means whatever the pricing tool shows, including discounts for terms...example, 12 month (25% off) is considered retail.

In summary:
1 zip - No "bundle discount", no split payments, no 6 month term. Retail price of 12 months only
2 zips - No "bundle discount", no split payments. Retail price of 12 or 6 month is ok
