An order bump is a small, relevant product offer displayed at checkout that the shopper can add to their order with a single click. No browsing, no product pages, no cart modifications — just a checkbox or button that adds the item instantly.
Think of the candy bars at the grocery checkout counter. That's an order bump in physical retail. The digital version is even more powerful because it can be personalized to match what the shopper is already buying.
Order bumps are among the highest-ROI tactics for increasing average order value. They work because they target shoppers who have already committed to buying — the hardest part of the conversion funnel is already done.
How Order Bumps Work
The mechanic is simple:
- Shopper proceeds to checkout with items in their cart
- On the checkout page (or cart page), a compact offer appears
- The offer shows a complementary product with a short description and price
- The shopper checks a box or clicks "Add" to include it
- The item is added to the order — no page reload, no redirect
The key characteristics that make order bumps different from cross-sells:
One click. No additional decisions (size, color, quantity). The product is pre-configured.
Low friction. The offer is inline with the checkout flow, not a detour.
Impulse-priced. Order bump products typically cost 10-30% of the cart total. Enough to matter for AOV, not enough to cause deliberation.
Contextually relevant. The offered product relates to what's already in the cart.
The Numbers Behind Order Bumps
Order bump acceptance rates vary by product, price, and placement, but typical ranges:
- Acceptance rate: 10-30% of shoppers who see the bump add it
- AOV increase: 10-30% (depending on bump product price)
- Revenue lift: 3-10% of total store revenue
Let's put this in dollars. A store doing $50K/month with a 15% order bump acceptance rate and a $12 bump product adds:
- 15% of orders multiplied by $12 = $1.80 average revenue per order
- At 1,000 orders/month: $1,800/month or $21,600/year in incremental revenue
For a feature that takes an afternoon to set up, that's exceptional ROI.
Product Selection: What to Offer as an Order Bump
The product you offer as an order bump is the single biggest factor in its success. Get this right and acceptance rates soar. Get it wrong and shoppers ignore it (or worse, it feels spammy).
Selection Criteria
Complementary, not competitive. The bump product should enhance what's already in the cart, not replace it or introduce a competing decision. Buying protein powder? Bump: a shaker bottle. Not: a different protein powder.
Low-consideration. The shopper shouldn't need to research the bump product. It should be obviously useful. "Do I need this?" should be answered with "Yes, obviously" in under 3 seconds.
Impulse-appropriate price. The bump product should cost 10-30% of the average cart value. For a $50 average cart, the bump should be $5-15. Higher than that triggers deliberation. Lower feels insignificant.
High margin. Since order bumps add revenue with zero incremental acquisition cost, even moderate margins are highly profitable. Digital products (ebooks, guides, extensions) have the best margins.
Universal relevance. The bump should work for a broad set of cart compositions. A product that's only relevant to 5% of orders isn't worth the real estate.

- Cart: laptop then Bump: screen cleaner kit ($9.99)
Placement Strategy
Where the order bump appears matters almost as much as what product is offered.
Checkout Page (Most Common)
The standard placement: the bump appears on the checkout page between the order summary and the payment section.
Advantages:
- Highest purchase intent (shopper is about to pay)
- The order total is visible, so the bump price feels incremental
- One-click add doesn't disrupt the checkout flow
Design: A compact card with a product image (small), product name, short benefit statement, price, and a checkbox. The checkbox should be unchecked by default — pre-checking is unethical and often illegal in some jurisdictions.
Cart Page
The bump appears on the cart page instead of or in addition to checkout.
Advantages:
- The shopper is still in "adding" mode (vs. "completing" mode at checkout)
- More screen real estate for product presentation
- Can show multiple bump options without cluttering checkout
Disadvantage:
- Lower purchase intent than checkout page
- Adding an item might change the cart, causing the shopper to re-evaluate
Before Payment Fields
Specifically positioned between the shipping section and the payment section on the checkout page.
Why this works: The shopper has entered their shipping info and is about to enter payment. They're committed but haven't yet typed their card number. This is the moment of lowest resistance to adding a small item.
Thank-You Page (Post-Purchase Upsell)
Technically this is a post-purchase upsell, not an order bump, but it works on the same principle. After the order is placed, the thank-you page shows an offer: "Add [Product] to your order for just $12.99. We'll add it to your shipment — no extra shipping cost."
Advantages:
- Zero conversion risk (the order is already placed)
- "No extra shipping" is a powerful incentive
- The shopper is in a positive state (just completed a purchase)
Disadvantage:
- Lower acceptance rates than pre-purchase bumps (5-15% vs. 10-30%)
Designing the Order Bump
The bump offer design should be compact, clear, and visually distinct from the rest of the checkout.
Visual Design
Distinct background. Use a light colored background (yellow, light blue, or light gray) to make the bump visually separate from the checkout form. It should be noticeable but not distracting.
Product image. A small thumbnail (80x80 to 120x120 pixels). The product should be visually recognizable at thumbnail size.
Headline. Short and benefit-focused. Not "Add Shaker Bottle" but "Never mix another lumpy shake — add a premium shaker."
Price. Clearly displayed. If there's a discount ("Usually $14.99, add for just $9.99 with your order"), show the discount prominently.
CTA. A checkbox with "Yes, add this to my order" or a button labeled "Add for $9.99." The checkbox pattern is less aggressive and converts well.
Copy That Converts
The copy on the bump offer needs to do three things in under 5 seconds:
- Explain what the product is
- Explain why it's relevant to this order
- Make the price feel insignificant
Template: "[Customer benefit statement]. Add [product] to your order for just $[price]. (Most customers grab this!)"
Examples:
- "Keep your supplements organized on the go. Add the 7-Day Pill Case for just $7.99."
- "Complete your skincare routine. Add the Travel Pouch for just $5.99 — fits all your products."
- "Don't forget the batteries. Add a 4-pack of AA batteries for just $4.99."
Dynamic Order Bumps
Static bumps (the same product for every checkout) work, but dynamic bumps (product changes based on cart contents) work better.
Cart-Based Rules
Set rules that determine which bump product to show:
- Category matching: Cart contains supplements, show shaker bottle. Cart contains skincare, show travel case.
- Price-based: Cart total under $50, show a $5 bump. Cart total over $100, show a $15 bump.
- Product-specific: Cart contains Product A, show Product B (its known companion).
- Exclusion: Don't show the bump product if it's already in the cart.
A/B Testing Bumps
Test these variables:
- Product. Test 3-5 different bump products to find which gets the highest acceptance rate.
- Price. Test the bump at different price points. Sometimes a higher price with a crossed-out "regular" price outperforms a lower price without context.
- Copy. Test different headlines and benefit statements.
- Placement. Test cart page vs. checkout page vs. both.
- Design. Test checkbox vs. button, with image vs. without, compact vs. expanded.
Run each test for at least 2 weeks or 500 checkout sessions. Measure acceptance rate, AOV impact, and total revenue lift — not just clicks.

Common Mistakes
Too many bumps. One bump is optimal. Two can work. Three or more clutters the checkout and triggers decision fatigue. The shopper's goal is to complete the purchase, not browse more products.
Irrelevant products. A bump that has nothing to do with the cart feels like spam. Always maintain contextual relevance.
Too expensive. A $50 bump on a $75 cart feels like a whole new purchase decision. Keep the bump at 10-30% of cart value.
Pre-checked checkbox. Adding the bump by default and requiring the shopper to uncheck it is unethical, may violate consumer protection laws, and damages trust. Always default to unchecked.
No mobile testing. The bump looks great on desktop but overlaps with payment fields on mobile. Test on real devices.
Competing with checkout. The bump should not distract from the checkout flow. If the shopper pauses to evaluate the bump and then leaves without completing checkout, the bump has done more harm than good. Keep it fast — a 3-second decision, not a 30-second evaluation.
Measuring Success
Primary metric: Revenue per checkout session. This captures both acceptance rate and bump product value. An increase here means the bump is working.
Secondary metrics:
- Acceptance rate (% of checkouts that include the bump)
- Checkout completion rate (make sure the bump isn't hurting conversions)
- Average order value (should increase)
- Bump product return rate (if high, you're offering the wrong product)
Red flag: If checkout completion rate drops after adding the bump, the bump is creating friction. Redesign, reposition, or change the product.
Order Bumps and AI Cart Filling
An interesting synergy: stores using AI cart filling often see higher order bump acceptance rates. Why?
When the cart is built by AI (via list input), the shopper arrives at checkout having spent less cognitive energy on cart building. They have more mental bandwidth to consider the bump offer.
Additionally, AI-filled carts tend to have more items (33% more on average), which means the bump's relative cost is smaller. A $9.99 bump on a $120 AI-filled cart feels more trivial than on a $40 cart.
Getting Started
Start simple:
- Pick one product that's complementary to your most popular items, low-cost, and high-margin.
- Write one headline that explains the benefit in one sentence.
- Set it live on the checkout page with a simple checkbox.
- Measure for 2 weeks. Track acceptance rate and checkout completion rate.
- Iterate. Try a different product, different copy, or different placement.
Order bumps are one of the few e-commerce tactics that reliably increase revenue with minimal downside risk. The cost of testing is near zero, and the upside is meaningful. If you're not using them yet, start this week.
