Increase AOV Without Increasing Ads Spend
Most stores ignore their biggest revenue opportunity: the post-purchase moment. Upsell Engine fixes that.
Order Bump Checkout
Upsell Engine injects a single-product offer directly into the WooCommerce checkout page, above the "Place Order" button. The customer's payment details are already stored, so accepting the bump adds the product to the order with one click — no re-entering card details, no second checkout flow. Conversion rates of 15-30% are typical because the customer is already in buying mode.
Frequently Bought Together
On each product page, Upsell Engine renders a "Customers also buy" widget showing 2-4 complementary products you configure. Shoppers can tick the add-ons and add the entire bundle to cart in a single click. You set the pairings manually per product — or apply category-level rules so new products are covered automatically.
Post-Purchase Offers
After an order completes, Upsell Engine queues a follow-up email through WooCommerce's native email system. The email contains a single focused offer with a time-limited discount code — typically sent 5-30 minutes after purchase while the buyer's satisfaction is highest. Because the recipient is already a customer, open rates run 40-60% above cold campaigns.
Basic Analytics
The Upsell Engine dashboard tracks every impression and acceptance for each bump and post-purchase offer. You see conversion rate, total extra revenue generated, and revenue per offer — updated daily. This is enough data to cut underperforming offers and double down on winners without needing a separate analytics tool.
Easy Setup
Install from WordPress.org, activate, and the Upsell Engine menu appears inside WooCommerce. Creating your first order bump takes about 5 minutes: pick a product, write a short headline, choose a trigger rule, and save. There is no shortcode to write, no template to edit, and no developer needed to go live.
Mobile Optimised
Order bumps and frequently-bought-together widgets are built with a mobile-first layout — full-width tap targets, readable font sizes, and no horizontal scroll. The bump renders below the cart summary on small screens so it never obscures the Place Order button. Post-purchase emails are responsive HTML and render correctly in Gmail, Apple Mail, and Outlook on iOS and Android.
What Upsell Engine Puts on the Board
Real numbers from stores using order bumps and frequently-bought-together offers.
15-25% AOV Lift
At $100 average order value, a 20% AOV lift means $20 more per order. At 200 orders/month, that's $4,000 additional monthly revenue from the same traffic.
Zero Extra Ad Spend
Upsells convert existing buyers — people already committed to purchase. No new traffic needed. CAC stays flat while revenue per customer climbs.
1 in 5 Customers Say Yes
Well-targeted order bumps see 15-30% acceptance rates. Even at 15%, on 100 orders that's 15 upsell conversions — pure margin gain.
Stores Using Upsell Engine
Three examples of AOV lifts driven by order bumps, frequently-bought-together, and post-purchase emails.
Phone Case Store
A phone case store added a "Screen protector bundle" order bump at checkout for $12.99 (the case was $24.99). 22% of customers accepted the bump. Result: AOV went from $24.99 to $27.84 — a 11.4% lift on every order.
Skincare Brand
A skincare brand showed "Frequently bought together" pairings on product pages — moisturizer + serum. 18% of product page visitors added both to cart. AOV increased by 34% from this single change.
Digital Course Creator
A WooCommerce course seller added a post-purchase email offering a discounted companion course (30% off, 48-hour window). 14% of buyers purchased the second course — adding $8,400/month in upsell revenue.
Upsell Engine vs. FunnelKit: AOV Without the Annual Fee
FunnelKit (formerly WooFunnels) is powerful if you need full funnel pages, advanced A/B testing, and Stripe-native checkout. But most stores just need a reliable order bump and a frequently-bought-together widget — and they don't need to pay $199/year for it.
| Feature | Upsell Engine | FunnelKit |
|---|---|---|
| Price | Free | $99-199/year |
| Order Bumps | ||
| Frequently Bought Together | ||
| Post-Purchase Offers | Email-based | Full funnel pages |
| A/B Testing | No (Pro coming) | |
| Full Funnel Builder | ||
| Setup Time | 5 minutes | Several hours |
If you're doing $5k+/month and want funnel pages, FunnelKit is worth it. If you want AOV without the overhead, Upsell Engine is free.
CartFlows ($149/year) is another paid alternative with a similar funnel-builder focus — the same trade-off applies.
