7 Proven Ways to Increase Average Order Value with Custom Product Options

Average order value (AOV) is one of the highest-leverage metrics in ecommerce. A 20% increase in AOV with the same traffic and conversion rate is a 20% increase in revenue — and product personalisation is one of the most natural, non-pushy ways to get there.

Here are seven tactics that real Shopify merchants use to increase AOV with custom product options.

1. Add a flat personalisation fee

The simplest approach: charge a flat fee for any personalisation.

This is common in jewelry, clothing, and home goods. A customer buying a $35 necklace pays $35. A customer who adds engraving pays $35 + $10 personalisation fee = $45.

The key is making the value exchange feel fair. Customers expect to pay extra for something unique. Price the fee based on your fulfillment cost plus a margin — typically $5–$20 depending on complexity.

With Customiras, you can attach a price modifier to any option type. When a customer selects or fills in a personalisation option, the price updates in real time on the product page.

2. Offer tiered personalisation complexity

Not all personalisation is equal. Simple text engraving is cheaper than a custom star map. Custom photo-to-watercolour is more complex than choosing a font.

Create tiers:

| Tier | What's included | Price uplift | |------|----------------|--------------| | Basic | Name or short text | +$8 | | Standard | Full personalisation + font choice | +$15 | | Premium | Photo upload + AI processing + preview | +$25 |

Let customers self-select their tier. Many will choose Standard or Premium — especially if you clearly communicate what they're getting.

3. Use gift-oriented options as soft upsells

Gift products are a major revenue driver for personalisation stores. Customers buying gifts spend more, have higher urgency, and are more likely to add extras.

Add options like:

• Gift wrapping (+$4.99)
• Handwritten gift message (+$2.99)
• Premium gift box (+$9.99)
• Gift receipt included (free, but positions as gift-ready)

These options are contextually relevant (not pushy) and have high attach rates — typically 30–60% of customers who see them will add at least one.

Pro tip: Use conditional logic to show gift-related options only when "this is a gift" is checked. This keeps the page clean for non-gift buyers.

4. Offer rush production / express fulfillment

Personalised products take longer to produce. That's a natural upsell opportunity.

Offer a "rush" tier that gets the order fulfilled in 1–2 business days instead of 5–7:

• Standard: Ships in 5–7 days
• Rush: Ships in 1–2 days (+$12.99)
• Next day: Ships tomorrow (+$24.99)

You'll be surprised how many customers — especially around birthdays and anniversaries — will pay a significant premium to get their order faster.

5. Upsell matching items in the option flow

While a customer is personalising a necklace, show them an option to add a matching bracelet with the same engraving:

"Add a matching bracelet with the same engraving? +$29"

This is a native upsell — it feels helpful, not pushy, because it's contextually relevant to what they're already buying.

With Customiras's conditional logic, you can show this option only after the customer has added their engraving text, making it feel even more seamless.

6. Create "premium material" options

Let customers upgrade the materials of their personalised product through the option selector:

• Bracelet material: Stainless steel / Silver-plated (+$5) / Sterling silver (+$15) / 14k Gold (+$45)
• Canvas print substrate: Standard paper / Canvas (+$15) / Premium gallery wrap (+$30)
• Mug quality: Standard ceramic / Premium 15oz / Travel tumbler (+$12)

The personalisation context makes customers more receptive to material upgrades. They're already invested in making something special — why not make it with better materials?

7. Use analytics to find your highest-converting options

This is where the data-driven merchants pull ahead.

Once you have Customiras's analytics dashboard running, you can see:

• Which options have the highest add rate (customers actually use them)
• Which options correlate with the highest AOV
• Which options have the highest abandonment rate (too confusing or too expensive)

Use this data to:

• Remove options nobody uses (simplify the experience)
• Promote high-add-rate options more visibly
• Adjust pricing on options with low add rates but high value potential

Real example: How one merchant added $11.40 to every order

A Shopify merchant selling custom pet portraits made three changes based on their Customiras analytics:

1. Added a "Premium gallery wrap" option at +$18 — 22% of customers chose it
2. Added a gift message option at +$2.99 — 47% of customers added it
3. Added express production at +$14.99 — 31% of customers chose it

Before: Average order value = $47 After: Average order value = $58.40

That's +$11.40 per order across 300 orders/month = $3,420 additional monthly revenue.

The app that enabled this costs $5/month. The math is absurd in the best possible way.
