Deal registration is a feature of some vendors' channel programs in which a channel partner, often a VAR (value-added reseller) or SI (systems integrator), informs the vendor about a lead and is given priority for it. Once a lead is registered with a vendor, the partner usually has a set period of time to close the deal. During this time other channel members, or even the vendor's own sales team, are not allowed to negotiate a similar deal with that lead. Not all vendors offer deal registration, and some vendors offer it only to certain channel partners.
Deal registration is usually put in place to lower the chance of channel conflict -- a situation in which channel partners have to compete against one another or the vendor's internal sales department. With a deal registration program in place, partners can work with a client without having to worry about another company trying to offer the same product at a lower price. Some vendors also offer to help partners in the selling cycle, and deal registration lowers the chance of the vendor stealing the lead once the partner has brought them into the discussion.
Even with deal registration in place, however, a vendor may occasionally give a lead to another partner or to its internal sales team. Typically this is done for extenuating circumstances, such as when the lead requests another partner.
