# Set limits on what your agent can spend

> What a Stamped Mandate can limit, and why those limits can't change once you've signed.

A Stamped Mandate is the only way your agent gets to spend anything. Every mandate limits the same three things, and you see all three before you sign.

<Steps>
  <Step title="Your agent proposes the limits">
    When your agent asks you to authorise a purchase, it proposes:

    * **How much** — an amount, in a real currency.
    * **What it's for** — a plain-language statement of what the mandate covers, plus any conditions attached to it (a price ceiling, which sellers qualify, a delivery deadline).
    * **How long it lasts** — an expiry. After that point, the mandate can no longer be used, even if it was never fully spent.
  </Step>

  <Step title="You review and sign">
    You see the amount, the statement, and the expiry together before you sign — see [Sign or decline an errand](/guides/approve-or-decline) for where that happens on each surface. For an errand, the most it may spend and the currency are set when you ask, and you sign them before anything is searched: you ask, you sign, then Sumvin searches, checks the merchant, watches for your conditions, and settles the purchase.
  </Step>

  <Step title="The limits are fixed">
    Once you sign, those three things are set. Your agent cannot raise the amount, widen what the mandate covers, or extend the expiry after the fact — it can only come back and ask you for a new mandate.
  </Step>
</Steps>

<Note>
  A spending mandate covers a purchase your agent makes as an errand. Sumvin is a [Visa Intelligent Commerce Launch Partner](https://www.visa.com/en-us/solutions/intelligent-commerce), and errands are built on Visa Intelligent Commerce. Payments aren't part of this preview: they arrive in a fast-follow release, with its own waitlist. Other ways of moving money aren't part of this yet.

<Tip>**Try asking your agent:** "Set up a spending limit of \$50 for groceries this week."</Tip>
