Overview
eBay Business Policies are reusable templates for payment, shipping, and return terms. Instead of setting these on every listing individually, a seller creates templates and applies them across listings - update the template once, and every listing using it updates automatically. These policies live on eBay's account settings, but they can be fully managed from within 3Dsellers as well - viewed, created, edited, and applied to listings - via Listings & Products → Business Policies.
How it works
Sellers opt in to Business Policies from their eBay account, then create policies from the Business Policies dashboard on eBay (or from 3Dsellers' own Business Policies page)
Each policy type (payment, shipping, return) can have multiple templates for different listing needs
Editing a policy updates every compatible listing using it automatically
Business Policies are specific to each eBay marketplace/site - a policy created on ebay.com doesn't carry over to ebay.de or ebay.co.uk; separate policies are needed per site
If policies are missing or out of sync in 3Dsellers, use the Sync Business Policies button on the Business Policies page to force a re-sync from eBay
Common gotchas
"Copy of..." policies: if a policy update fails to apply to some listings (e.g. a listing has a pending offer or is about to expire), eBay auto-generates a "Copy of..." policy to preserve the old terms on those listings, so there's no unexpected change to a live listing's contract with a buyer.
Random-character policy names: these are auto-generated spin-off policies created when a policy revision partially failed - the original policy keeps the new terms, and the spin-off preserves the old terms for listings that couldn't be updated.
Restricted listings: if a listing shows as "restricted" during a policy update, it can't be changed until it ends, or until any pending offers on it are accepted/declined.
Opting out: active listings keep working, but new policy changes require setting payment/shipping/returns per listing again unless the seller opts back in (old policies aren't restored - new ones must be created).
New policy with identical settings silently ignored by eBay: this is a known eBay behavior, not a 3Dsellers bug. If a seller creates a brand new policy with the exact same settings as an existing one, and then tries to update listings to use this new policy, eBay simply ignores the change and returns no error - the listing keeps its original policy assignment. For a policy change to actually take effect on eBay's side, the new policy's settings need to be meaningfully different from the old one (not just a different name/ID).
Is this an eBay restriction or a 3Dsellers issue?
eBay-side: a policy won't update on certain listings (restricted/pending offer/about to expire); "Copy of..." or randomly-named policies appearing; opt-in/opt-out errors tied to a backlog of existing policies on the account; a listing not switching to a newly created policy that has identical settings to its current one (see gotcha above - this is eBay silently ignoring the change, not a failed sync).
3Dsellers-side: the wrong business policy is being applied when creating/editing a listing through 3Dsellers; a listing shows a different shipping/return policy in 3Dsellers than what's actually live on eBay; bulk actions in 3Dsellers aren't reflecting policy assignment correctly; policies appear missing or outdated in 3Dsellers (try Sync Business Policies first).
Tip: since Business Policies live on eBay's account settings, the fastest way to confirm which policy is really active on a listing is to check it directly on eBay (or via eBay's Manage Business Policies page, or 3Dsellers' own Business Policies page) and compare against what's expected. If a policy switch isn't taking effect, first check whether the new policy's settings actually differ from the old one - if they're identical, eBay won't apply the change.
