Is there a way to block orders over a specific dollar amount, or accept as manual payments only?

Payments + Shipping & Fulfilment

Topic summary

Goal: prevent or gate orders over a set dollar amount to reduce fraud, ideally with free/low-cost tools.

Key constraints and clarifications:

  • Shopify Fraud Filter can auto-cancel, but only after payment capture—still exposes you to chargeback risk.
  • Manual payment capture (authorize now, capture later) is a global store setting; not configurable per-order by default.

Approaches suggested:

  • Global manual capture + automation:
    • Disable automatic capture, then use Shopify Flow to: cancel high-risk orders; auto-capture for low-risk or lower-value orders using the capture-payment action.
    • Alternatives with similar logic: Mesa workflow (can key off risk score or order total) and Mechanic (robust risk tasks).
  • Block before order placement:
    • Checkout-level: a Shopify Functions app can prevent checkout when total exceeds a threshold.
    • Cart-level: theme customization to disable checkout buttons when cart total exceeds a set amount, or use an order-limits app.
  • App example: Cart Lock can block carts over a specified total; set a rule on “Cart total > X” and show an error message at checkout.

Status: No native per-order capture rule; multiple viable app/automation paths. No final decision from the original poster; discussion remains open.
