Adobe negotiates these deals every day. You do it once every three years. The account team knows your renewal date, your usage, and the budget cycle you are working against, and they build the quote to land exactly where they want it.
Most buyers react to the proposal Adobe puts in front of them. By then the anchor is set and the timeline favours the vendor. The leverage you had at the start of the cycle has quietly drained away.
We change the order of play. We set the strategy first, bring the peer benchmarks that show what good pricing looks like, and hold a clear walk position so the vendor negotiates against your plan instead of you negotiating against theirs.
