How to Switch Ecommerce Agencies Without Losing Sales

Unhappy with your Amazon or ecommerce agency? How to spot the warning signs, take back your accounts, switch agencies safely and fix the mess left behind.

---

Switching agencies feels risky. Your ads, listings and account settings are tangled up with the people running them, and nobody wants a sales dip while things change hands.

But staying with an agency that isn’t working costs more. Here’s how to tell when it’s time, and how to switch without losing ground.

Signs it’s time to switch

• Ad spend keeps rising, sales don’t. Nobody can explain where the money goes.
• Reports full of clicks and impressions, but nothing about profit.
• Listings haven’t changed in months. Same images, same copy, falling conversion.
• Warnings go unanswered. Account health issues, suppressed listings or stranded inventory sit for weeks.
• Slow replies. Urgent problems wait days for a response.
• You don’t know who does the work, or you suspect it’s been offshored or handed to someone else.
• They sell their own products. That’s a conflict of interest. See why your Amazon agency shouldn’t sell products.

Step 1: Make sure you own everything

Before you give notice, check that the important accounts are in your name:

• Seller Central or Vendor Central.
• Brand Registry.
• Amazon Ads, Google Ads and Google Merchant Center.
• Shopify, your domain and your analytics.
• Your images, videos and other creative files.

Your agency should be a user on your accounts, not the owner. If they own anything, ask for it to be transferred now.

Step 2: Export your data

Download what you can before access changes: ad reports, search term reports, sales and inventory history, and any creative files. Months of history matter when the new team rebuilds campaigns.

Step 3: Get an independent audit

Have the new team review your accounts before the switch. A good audit shows:

• Where ad spend is wasted.
• Which listings are underperforming or suppressed.
• Account health risks.
• Whether tracking can be trusted.
• What to fix first.

Step 4: Plan the handover

• Agree a switch date and notice period with your old agency.
• Ask them not to make big changes during the notice period.
• Add the new team as users before the old team is removed.
• Keep campaigns running. Pausing everything during a switch can hurt rankings, especially on Amazon.

Step 5: Remove old access

Once the new team is in place, remove the old agency’s user access from every account, and change any shared passwords. It’s a simple step that’s often forgotten.

Step 6: Fix urgent problems first

A good new team doesn’t tear everything down on day one. It fixes the urgent things first, like runaway ad spend, account health warnings and suppressed listings, then rebuilds the rest step by step.

The bottom line

Switching agencies is safe when you own your accounts, keep your data and hand over in an orderly way. Then the new team can fix what’s broken and get you growing again.
