How to Add Post-Purchase Upsells to Your Squarespace Store
Post-purchase upsells are one of the most underused revenue opportunities in ecommerce. Most Squarespace store owners focus entirely on converting visitors before they check out. But the moment after checkout — when a customer has just completed a purchase and is still on your site — is one of the highest-converting moments in the entire customer journey.
Here's how to add post-purchase upsells to your Squarespace store and what to expect from them.
Why Post-Purchase Is Different
Before checkout, a customer is evaluating. They're deciding whether to buy, comparing options, checking the price. Adding an offer at this stage requires overcoming that uncertainty.
After checkout, all of that is gone. The decision has been made. The customer is happy — they got what they wanted. Their guard is completely down. They're in the most positive, open state they'll be in during their entire relationship with your store.
This is why post-purchase offers, when relevant, convert at surprisingly high rates. You're not selling to a skeptic — you're selling to a happy customer.
The Two Post-Purchase Pages on Squarespace
Squarespace has two pages that appear after a customer completes an order:
Order Confirmation Page: The "thank you" page that appears immediately after checkout. The customer sees their order summary and confirmation details. They're still warm — they just completed the purchase.
Order Status Page: The tracking page customers return to while waiting for delivery. Most customers visit this page multiple times — checking when their order will arrive, looking at the items they ordered. Each visit is another opportunity.
UpsellGrow supports post-purchase offers on both pages, with four position options each (top, left, right, bottom of page).
What Kind of Offers Work Post-Purchase
Complementary products: Something that pairs naturally with what they just bought. If they bought a coffee grinder, suggest the matching beans or a cleaning kit. The purchase they just made is context — use it.
Complete-the-set suggestions: If the purchase is part of a natural set, show them the rest of the set. If they bought one volume of a series, show them the others.
Frequently bought together: UpsellGrow's FBT offer type works on post-purchase pages too — it shows what other customers who bought the same thing also purchased afterward.
What doesn't work: Generic suggestions, catalog dumps, high-pressure language. Post-purchase offers need to feel like a natural continuation of the customer relationship, not a second sales pitch.
One Important Note About Post-Purchase Checkout
Unlike some platforms that offer "one-click" post-purchase upsells (where a customer can add a product without re-entering payment details), Squarespace requires a new checkout for any post-purchase addition. The customer will need to go through checkout again.
This slightly reduces the conversion rate compared to one-click systems. But customers who are genuinely interested in a relevant suggestion will still complete it — especially if the offer is well-targeted and the price is right.
How to Set Up Post-Purchase Upsells With UpsellGrow
UpsellGrow handles post-purchase offers on both the confirmation and status pages natively. Here's the setup:
- Click "New Offer" in the UpsellGrow dashboard
- Select "Order Confirmation" or "Order Status" as the location
- Choose your offer type (cross-sell, bundle, or FBT)
- Configure the offer — for confirmation and status pages, UpsellGrow uses priority rank to determine which offer shows for each order (rather than a specific trigger product)
- Select the position (top, left, right, or bottom of page)
- Customize the widget and add any conditions
- Publish
The offer goes live on every order confirmation and status page immediately.
Managing Multiple Post-Purchase Offers
When multiple post-purchase offers are active, UpsellGrow's priority system determines which one shows for each order. You set the priority rank on the Offers page by dragging to reorder. Rank 1 wins. The dashboard shows exactly which offer is showing and which is being skipped, so you have full visibility into the system.
