When the commission is considered earned
Some plans say a commission is earned at signing, while others require payment, shipment, activation, or continued employment. That timing often controls which rate applies.
Short Answer
In California, the answer usually depends on the terms of the commission plan, when the commission was earned under that plan, and whether your employer gave effective notice of the change before the work or sale was completed. In general, employers can change commission plans going forward, but they usually cannot take away compensation that has already been earned under an existing agreement.
If a customer already signed, that does not automatically mean the old rate or the new rate applies. The key question is often when the commission is considered “earned” under the written plan, offer letter, handbook, or other agreement. Some plans say commissions are earned only after payment is received, after a return period passes, after the account activates, or after the employee remains employed on a certain date. Other plans may tie earnings to a signed order or completed sale.
If your employer changed the plan after the customer signed, the change may apply only to future transactions or future work unless the employer clearly communicated the change and the relevant commission had not yet been earned. If the commission was already earned under the earlier terms, California wage rules may treat it as compensation that cannot usually be withheld just because the employer later changed the plan.
That said, the exact answer is highly fact-specific. A plan might let the employer modify commissions prospectively, and some employers make changes effective immediately for deals that are still pending. Whether that is enforceable can depend on the language of the plan, how notice was given, whether you accepted the new terms by continuing to work, and what part of the sales process had already happened when the change was made.
In California, commission pay disputes often turn on written agreements and wage-payment rules. If your employer changed the plan after a customer signed, the most important documents are the plan itself, any updates, your offer letter, emails about the change, and records showing when the sale was made and when the commission supposedly vested or became payable.
Because commission cases are very fact-sensitive and California law can differ from other states, it is often wise to talk with a California employment lawyer or another qualified professional if the amount is significant or if your employer is refusing payment.

What This Question Usually Means
People asking this usually want to know whether they are entitled to the commission rate that existed when the customer signed, or whether a later plan change controls. The real issue is often not just the signature date, but when the commission was earned, vested, or became payable under the written terms.
General Legal Rule
In California, employers generally may change commission plans prospectively if they give proper notice and the change does not take away commissions already earned under an existing agreement. Whether the old or new rate applies usually depends on the written commission plan, the timing of the change, and when the commission was earned according to the plan’s terms.
Key Factors
What the written commission plan says
The plan language may say the employer can change rates, when changes become effective, and whether pending deals are covered by the old or new terms.
Whether notice was given before the relevant event
A change made after a commission was already earned may be less likely to control that commission. If the sale was still in progress, the employer may argue the new terms apply.
Whether you accepted the change by continuing to work
In many workplace settings, continuing to work after receiving notice of new terms may matter. The legal effect can depend on the wording of the plan and the surrounding facts.
Whether the commission is treated as wages under California law
Commissions are often treated as wages once earned. That can affect whether an employer may later reduce, revoke, or delay payment.
Whether there were conditions such as returns, cancellations, or chargebacks
Some plans allow adjustments if a sale cancels, a customer returns a product, or the transaction never fully closes. Those conditions can affect the amount owed.
When to Talk to a Lawyer
Consider speaking with a California employment lawyer if the commission amount is substantial, if the written plan is unclear, if the employer changed the rate after the deal seemed complete, or if the employer is refusing to explain the calculation. A lawyer can review the documents and explain how California wage rules may apply. This page is general information only and does not create an attorney-client relationship.
