Commissions are wages once earned under the agreed plan; § 23-353 governs when they must be paid, and an unpaid commission can support a treble-damages claim.
Employers usually argue the commission was not "earned" yet. The answer is in the plan's own words: if every condition the plan sets had been satisfied before you left, the timing clause moves the payment date, it does not erase the debt.
A demand letter fixes three things at once: the amount, the date each item was due, and the date the employer was on notice. Every forum that can help you — the Industrial Commission of Arizona — Labor Department, a small claims judge — starts from those three facts. The letter is built from A.R.S. § 23-353; § 23-355 (treble damages) and your own figures, so the deadline it states is the one that applies to your separation, not a generic thirty days.
If the amount fits inside $3,500, small claims court is usually faster than an agency queue; if it does not, the agency route and a demand first is the cheaper path.

A clause that forfeits commissions already earned is the clause most often struck down when challenged. The employer can usually set the timing of payment; it is much harder for it to keep money the plan says you earned.
