When a seller uses the “Contact Merchant” (message‑based) checkout on their Facebook shop/catalog and then tries to onboard to Instagram Shopping, the key thing that happens is that they will not be able to use core Instagram Shopping features (like product tagging and an in‑app shop) until they switch to a supported checkout type that meets Meta’s current requirements, especially in markets like the US where native checkout is now mandatory for Shops.

Below is a clear breakdown in a slightly story‑style format, with sections, bullets, and SEO‑friendly framing that matches your post template.

Quick Scoop: What Actually Happens

Imagine a seller who already has a Facebook catalog set up with “Contact Merchant” as the checkout method (customers click and then message or otherwise contact the business to buy). When they later try to onboard this same catalog for Instagram Shopping, Meta checks whether the account and the checkout setup meet Instagram Shopping requirements.

In markets where Meta now requires “Checkout with Facebook or Instagram” to keep Shops active (for example, US businesses as of April 24, 2024), a “Contact Merchant” flow is treated as non‑compliant for a full Instagram Shop experience. This typically leads to:

  • No access to in‑app product tagging on Instagram until checkout is updated.
  • Loss or absence of an active Instagram Shop (the shop or some features may be inactive or unavailable).
  • Prompts inside Commerce Manager to change checkout method before continuing setup.

So, the short practical answer: if you stay on “Contact Merchant,” Instagram Shopping onboarding will either stall or be heavily limited, and you’ll be pushed to switch to “Checkout with Facebook or Instagram” (native checkout) or another supported method, depending on your country.

Why “Contact Merchant” Causes Issues

Meta distinguishes between different checkout methods in Commerce Manager:

  • Checkout with Facebook or Instagram (native, in‑app checkout).
  • Checkout on another website (e.g., “View on website,” sending shoppers to your own ecommerce store).
  • Message‑based / “Contact Merchant” style flows (customer messages the business instead of hitting a structured checkout).

For US‑based businesses, Meta rolled out a major change: to keep a Facebook or Instagram Shop visible, they must enable “Checkout with Facebook or Instagram.” If they don’t, the shop can become inactive and product tagging on Instagram can stop working.

That means:

  • A catalog that was fine with “Contact Merchant” on a Facebook Page may fail to qualify for the full Instagram Shopping setup.
  • During Instagram Shopping onboarding (via the FBE/Facebook Business Extension flow), Meta reads the commerce setup, including checkout method, and checks eligibility and compliance.
  • If the checkout doesn’t meet the current policy, the seller will see prompts to change their checkout method and may not get approved for product tagging or an active Instagram Shop until they do.

Step‑by‑Step: What the Seller Experiences

Here’s a typical narrative of what happens when such a seller tries to onboard:

  1. They start Instagram Shopping setup
    • From Instagram, they tap to “Set up Shop” or “Set up Instagram Shopping,” which launches the Meta commerce setup flow (FBE click‑through).
  1. Meta inspects their existing commerce account
    • The flow checks: business eligibility, policy compliance, catalog configuration, and checkout method.
  1. “Contact Merchant” is detected
    • If the commerce account is configured with a non‑native checkout that does not meet the current requirements (e.g., message‑based checkout in a region where that’s no longer supported for Shops), the onboarding either:
      • Blocks progression at a step that asks them to select or update checkout method , or
      • Allows them through but leaves Instagram Shopping features like product tagging disabled until changes are made.
  1. They are nudged to update checkout
    • In Commerce Manager → Settings → Checkout method, they’ll be prompted to switch to “Checkout with Facebook or Instagram” (US) or another allowed option.
 * Meta may explicitly say that Shops will be inactive and Instagram product tagging unavailable unless native checkout is enabled.
  1. After changing checkout
    • Once they move from “Contact Merchant” to a compliant method and complete the required business setup (payout info, shipping, returns, etc.), their commerce account can pass review.
 * Only then can the Instagram Shop be fully enabled and product tagging start working across posts, Stories, and Reels.

Marketplace Reality in 2025–2026

Since Meta’s 2023–2024 rounds of changes, the trend has been aggressively toward native checkout in supported markets, especially the US:

  • US Shops:
    • Must use “Checkout with Facebook or Instagram.”
    • If they don’t, the Shop can be hidden or deactivated, and you lose access to product tagging and some audience tools.
  • Some international markets:
    • Still allow Shops that link out to a website checkout or use more flexible setups, though this may change over time.
* Even there, Instagram Shopping still expects a properly configured commerce account and compliant products.

So, a “Contact Merchant” approach is increasingly treated as a legacy or limited flow, not a supported baseline for Instagram Shopping going forward.

Practical Advice for Sellers

If a seller is currently using “Contact Merchant” on their Facebook Page/catalog and wants to onboard successfully to Instagram Shopping, they should:

  • Switch checkout method in Commerce Manager
    • Go to Commerce Manager → select shop → Settings → Checkout method → switch to “Checkout with Facebook or Instagram” (US) or another approved checkout method.
  • Complete all required business settings
    • Add payout details, shipping methods, customer service info, and policies; this is important for being approved for native checkout and Instagram Shopping.
  • Ensure catalog and products meet policy
    • Verify item titles, images, and descriptions follow commerce policies and do not trigger rejections; early catalog clean‑up helps the account get approved.
  • Monitor status and notifications
    • Use Commerce Manager to check for errors, status changes, or requests for more info on the commerce account and channels (Facebook vs Instagram).

Bottom Line (TL;DR)

If a seller uses the “Contact Merchant” checkout method on their Facebook Page/catalog and then tries to onboard to Instagram Shopping, they’ll run into approval or feature‑availability issues until they move to a compliant checkout method (typically “Checkout with Facebook or Instagram” in the US). Instagram will not fully enable product tagging or a visible Shop until that change and the related business setup and review are complete.
