Integrate Square into OpenAI Ads custom audiences
Square knows who buys from you, who subscribes, who joined your loyalty program, and who has gone quiet. Connect it to Bluegrass and that customer state becomes audiences you can target or hold out on OpenAI Ads, each with its own bid.
Your data is only used to build your audiences · never sold
What you can do with Square on OpenAI Ads
Businesses that take payments through Square build up a clear record of their customers across transactions, subscriptions, and loyalty. Bluegrass reads customer and subscription state, not card numbers, and turns it into custom audiences on OpenAI Ads. We only ever use your data to build and update your audiences, and you can disconnect Square whenever you want.
Once Square is connected you can split people by how they engage with your business. Active subscribers, subscriptions that cancelled, recent buyers, loyalty members, and customers who have not come back in a while all become separate lists, and you decide whether each one gets a higher bid or gets held out of prospecting entirely.
Custom audiences you can build from Square
Each one can be a target audience with its own bid, or a suppression list you hold out from prospecting.
Target the right people, exclude the rest
Win back and bid more
Put more budget behind cancelled subscriptions, lapsed customers, and loyalty members worth a nudge. These people already bought from you, so a measured bid increase usually pays back faster than cold reach.
Stop paying for current customers
Hold active subscribers and recent buyers out of your acquisition campaigns. There is no reason to buy clicks from people who already pay you, so that budget moves to new demand.
Common ways advertisers use Square
Win back cancelled subscriptions
Build an audience of customers who cancelled in the last quarter and raise your bid to bring them back before they take their spending elsewhere.
Bring back lapsed customers
Reach buyers who have not returned in a while and increase your bid to win the next visit while your brand is still familiar.
Reward loyalty members
Set higher bids for look-alikes of your loyalty members so prospecting spend leans toward customers most like the ones who come back.
Connect Square in three steps
Connect Square
Authorize Bluegrass with read-only access to your Square customers, subscriptions, and loyalty. No card data is ever read or stored.
Pick the segment
Choose a customer state, like cancelled in the last 90 days or loyalty members. Bluegrass takes the matching customers and builds the audience for you.
Set a bid and launch
Mark the audience as a target or a suppression, give it a bid adjustment, and layer day parting on top before it goes live.
Your data stays yours
Bluegrass only uses your customer data to build and update your audiences on OpenAI Ads. We never sell it or use it for anything else, and you can disconnect any time.
- Bluegrass reads who buys, who subscribes, and who is in your loyalty program, never card numbers or payment details
- We only use your data to build and update your audiences, never to sell or for anything else
- Audiences refresh as customers buy and subscriptions change, so a subscriber who cancels moves into your win-back list automatically
Pair it with a goal and a schedule
Suppress existing customers
The fastest way to waste a prospecting budget is to spend it on people who already bought. Build a suppression audience from your customer list and hold them out, so every acquisition dollar goes to someone new.

Audiences decide who you bid on. Day parting decides when, so budget lands in the hours that convert.

Square and OpenAI Ads, answered
What Square data does Bluegrass use?
Customer and subscription state: who is active, who cancelled, who bought recently, and who is enrolled in loyalty. Bluegrass never reads card numbers or raw payment details.
Can I suppress my current customers from ads?
Yes. Mark your active subscribers and recent buyers as a suppression audience and they are held out of prospecting, so you stop paying to reach people who already buy from you.
How does this handle someone who cancels?
Audiences refresh as Square changes. When a subscriber cancels they drop out of your active list and move into your win-back audience on the next sync.
Is my customer data safe?
Yes. Bluegrass only uses your data to build and update your audiences for OpenAI Ads. We never sell it, share it, or use it for anything else. You stay in control the whole time, and you can disconnect Square or remove your data whenever you want.
