Ad accounts transfer by platform rules, and supplier contracts move only if the supplier agrees. Google Ads uses a billing change or MCC handover. Meta moves the ad account but not the pixel, which never moves between Business Managers, so plan a fresh one before close. A supplier contract needs the supplier's consent if it has an anti-assignment clause.

How Do Google Ads and Merchant Center Move?
Google Ads uses one of two paths: the billing change-who-pays transfer, which carries a 7-day approval window, so start it early, or a straight MCC control handover between agencies. Either way, confirm the buyer's payment profile is live before the seller's is removed. Merchant Center works differently: add the buyer as admin, remove the seller, then re-verify the site claim immediately. Losing that claim mid-transfer is a known risk that can quietly break Shopping ads after the handover looks finished, which is why Kairos treats the re-claim step as part of the same checklist item rather than an afterthought. On Kairos, the Google Ads move is a critical task, meaning the deal cannot close until it is done; the Merchant Center re-claim sits on the same checklist without gating the close.
What About Shopify Payments Re-Verification?
Shopify Payments does not auto-update the legal entity or tax ID when ownership changes - the buyer has to re-enter both in Settings > Payments themselves. Shopify takes 24 to 72 hours to re-verify, and payouts can pause during that window, so line up a cash buffer before closing rather than finding out about the gap when a payout does not land. On Kairos, this re-verification is a critical task: escrow does not release until it is marked done, alongside the Shopify store transfer, the Google Ads move, and the domain transfer.
What Happens to the Meta Ad Account and Pixel?
Only ad accounts owned by a Business Manager can transfer to the buyer, and even then the pixel itself does not move between Business Managers. Its audience data and ad-learning history stay on the seller's side, which is easy to miss because the ad account changing hands looks like the whole job is done. The buyer needs a pixel strategy agreed before close, in most cases a fresh pixel rebuilt on their own Business Manager with key audiences and events reconstructed rather than inherited. This is not a step Kairos gates the close on, but it is the fact most likely to surprise a buyer who assumes performance history travels with the account. Confirm Business Manager ownership at listing time, not on closing day, and decide the pixel plan early enough that the buyer's campaigns are not learning from zero the week they take over.
Do Supplier Contracts Automatically Transfer?
A supplier contract does not automatically survive a change of owner. Most supplier agreements carry an anti-assignment clause, and that clause means the supplier has to actively consent before the relationship carries over to the new owner - it is not a formality that happens by notifying them after the fact. A seller who has not already checked this with their key suppliers is promising something they may not be able to deliver, and the buyer's Kairos due diligence checklist has a line item for exactly this: supplier terms are checked for assignability, and any contract that needs consent is flagged right there on the checklist. If a supplier says no, or goes silent, the buyer inherits the relationship risk, not a guaranteed contract. Ask suppliers early, in writing, and treat any anti-assignment clause as a task with an owner and a deadline, the same as every other item on the transfer list.
What About the Domain, Trademarks, and Social Accounts?
The domain moves by an EPP or auth-code transfer, and it has a real calendar trap: ICANN enforces a 60-day lock after a domain is registered or updated, so a recent renewal or registrar change can stall the whole thing. Check this at listing time, not on closing day. Trademarks move by a formal assignment that includes the goodwill of the mark, then gets recorded, and the recording carries its own modest fee; assigning a mark without its goodwill can undermine it, so the wording matters as much as the signature. Social accounts move through each platform's own reassignment flow for business accounts, such as TikTok Business Center, while a personal account breaks the platform's terms of service if sold and should be flagged honestly rather than listed as a transferable asset. Paid Shopify apps are not named on any standard asset list, so check whether each app's data and settings move with the store or need reinstalling.
In What Order Does All This Happen?
Order runs by dependency and owner, not by convenience. On Kairos, every one of these items is a tracked task in the deal room, each with its own owner and status, so nothing is a verbal promise that quietly slips. Some are critical to the close: the Shopify store transfer, the Shopify Payments re-verification, the Google Ads move, and the domain transfer are gating tasks, meaning escrow does not release until each is marked done. Others matter just as much for the business but do not block the close itself: Merchant Center's re-claim, the Meta pixel plan, trademark assignment, and social reassignment. Start the domain check and the pixel plan at listing time, since both carry deadlines that predate the deal itself; start the Google Ads billing transfer as soon as the deal is signed, since its approval window runs days, not hours. Supplier consent belongs in the same early window, asked before signatures, not after.
