Meta has removed the existing customer budget cap from Advantage+ sales campaigns. If you used it to stop your budget drifting to people who already buy from you, that setting is gone. Meta’s Business Help Center now documents two ways to rebuild the control by hand: run a campaign that spends nothing on existing customers, or run one that splits budget between new and existing customers.
The campaign hasn’t lost interest in your past buyers. What changed is who manages that appetite. Now it’s you.
Key takeaways
- The existing customer budget cap is no longer available in Advantage+ sales campaigns.
- Meta documents two rebuild paths: exclude existing customers, or split budget between new and existing customers.
- Custom audience exclusions are a hard control. Custom audiences you add as inclusions are only suggestions.
- No coverage we reviewed flags a regional restriction, so Australian accounts should assume the change applies to them.
What happened to the existing customer budget cap?
The cap was an optional setting in the original Advantage+ Shopping campaign. It let you limit how much of your budget went to people who already knew your brand. AdManage.ai’s 2026 guide to the product says the feature no longer exists. BrandRocket quotes Meta’s own help page saying the cap “is no longer available”.
The removal came with a wider rebuild. What most advertisers still call Advantage+ Shopping, or ASC, is now the Advantage+ sales campaign, sometimes shown as the Advantage+ campaign experience. Meta describes it as the option for advertisers using the sales objective to drive online sales. Ad sets are back too, and each one holds up to 50 ads.
Why does this matter for your ad spend?
Past customers are the easiest sale in your account, and an automated campaign will keep finding them. BrandRocket’s analysis puts it plainly: past buyers click more, buy faster and need less convincing. When more budget drifts their way, reported results can look healthier while the number of genuinely new customers stays flat.
For a retailer paying Meta to grow, that’s the risk. You can end up buying ads for people your emails or your shopfront would have brought back anyway. The cap was a simple guard against that. The guard now has to be built from other controls.
The two rebuild options Meta documents
Meta’s help page, “How to replicate existing customer budget cap”, sets out two paths.
Option 1: spend nothing on existing customers
Build the campaign with your existing customer audiences excluded. Every dollar then goes to people who haven’t bought from you. This holds because custom audience exclusions are one of the hard controls in Advantage+ Audience, alongside location, minimum age and language. Meta treats them as rules, not hints.
It suits offers built only for newcomers, such as a first-order discount you’d rather your regulars didn’t see.
Option 2: split budget between new and existing customers
Run one campaign with two ad sets. One reaches existing customers. The other reaches everyone else, with existing customers excluded. Keep the existing customer ad set deliberately small. It’s the closest thing to the old cap, rebuilt from parts.
One detail decides whether the split works. In Advantage+ Audience, custom audiences, lookalikes, age ranges, gender and detailed targeting are suggestions, and Meta can deliver beyond them. If your customer list goes in only as a suggestion, the existing customer ad set isn’t fenced to those people. Check how each audience is set before you trust the numbers.
Which option suits your store? A worked example
The business below is hypothetical. It illustrates the decision, not a real account or real results.
Picture a Fremantle homewares store that sells online. It has a few thousand past customers in its email platform and runs one Advantage+ sales campaign. It used the old cap to keep spend on existing customers small, because its monthly email already brings regulars back.
The owner has two jobs for the quarter: a first-order offer for new customers, and steady reminders to past buyers before Christmas.
Option 1 fits the first-order offer. Regulars can’t claim it, so showing it to them wastes money and may irritate them. A separate campaign that excludes existing customers keeps the offer in front of new people only.
Option 2 fits the ongoing sales campaign. Past buyers do come back before Christmas, so cutting them out would throw away a useful audience. A split with a deliberately small limit on the existing customer ad set keeps that reach without letting it take over.
Change two facts and the answer changes. With a small customer list or a tight daily budget, two ad sets split the conversion data each one learns from. Then one campaign with the exclusion, plus email for regulars, is the simpler call.
What to check in your account this week
- List every Advantage+ sales campaign that relied on the old cap. Those campaigns are now running without it.
- Make sure your existing customer audience is current. Refresh your customer list upload and confirm your website purchaser audience is still filling.
- Decide what each campaign is for: new customers only, or new and existing. Match it to Option 1 or Option 2.
- Confirm your existing customers sit in the exclusion control, not as a suggestion. Exclusions are the rule Meta always follows.
- Judge results on cost per new customer, not blended return. Expect the blended figures to look worse once cheap repeat sales are capped. That’s the real cost of growth showing up.
Does this apply to Australian advertisers?
Yes, as far as any source shows. Advantage+ is a global product line, and no regional restriction is flagged in any coverage we reviewed. That isn’t a statement from Meta, so treat it as the working assumption and confirm it in your own Ads Manager.
The decision still needs an owner
The setting is gone. The question it answered is not. How much of your Meta budget should go to people who already buy from you? Pick that number deliberately, then build the campaign to hold it.
