Service Add-ons (Extras)

Add-ons let vendors offer optional upgrades that buyers can select during checkout. They are a proven way to increase order value while giving buyers flexibility to customize their order.

Service Add-ons Interface

Add-ons are perfect for offering:

  • Rush delivery – Pay extra for faster turnaround
  • Source files – Get the original design files (PSD, AI, etc.)
  • Extra revisions – Add more rounds of changes beyond what the package includes
  • Commercial license – Use the work for commercial purposes
  • Additional pages or items – Scale up the deliverable
  • Priority support – Get faster responses during the project

There are four types of add-ons, each suited to different situations:

The most common type. Buyers simply check a box to add it.

Best for: Rush delivery, source files, commercial license, priority support

Example: “Include source files” – $20 flat fee

Buyers pick one option from a list. Great when there are multiple tiers of an upgrade.

Best for: Resolution options, format choices, delivery speed tiers

Example: “Video resolution” – 720p (free), 1080p (+$10), 4K (+$25)

Buyers type in custom information. This can be free or carry an additional charge.

Best for: Personalization text, business names, custom inscriptions

Example: “Business name for the logo” – no extra charge, just information gathering

Buyers choose a number, and the price multiplies accordingly.

Best for: Extra revisions, additional pages, extra hours, extra items

Example: “Additional revisions” – $10 each, select 1-5

Free Pro
Add-ons per service 3 Unlimited [PRO]

When the free version limit is reached, the wizard lets vendors know they can upgrade to Pro for unlimited add-ons.

A fixed price added to the order total, regardless of which package the buyer selected.

Example: Source files = +$30, whether the buyer chose Basic or Premium.

Price multiplied by the number the buyer selects.

Example: Extra pages = $20 each. Buyer selects 3 = $60 total.

After selecting a package, buyers see the available add-ons listed below. Each add-on shows:

  • The add-on name and description
  • The price (or “Free” if no charge)
  • Any impact on delivery time (e.g., rush delivery subtracts days, extra work adds days)

Selected add-ons are added to the order total at checkout. This applies regardless of whether the add-ons were created through the frontend wizard or the wp-admin service editor.

Add-ons can change the delivery timeline:

  • Add time – Extra work like additional pages might add 2 days
  • Reduce time – Rush delivery might subtract 3 days from the timeline

This is calculated automatically and shown to the buyer before checkout.

  • Price add-ons at 20-40% of your base package price – This feels like a fair upgrade without being too expensive
  • Keep it to 3-5 add-ons – Too many options overwhelm buyers and reduce conversions
  • Lead with your most popular add-on – Rush delivery and source files are typically the most selected
  • Use checkboxes for 90% of add-ons – They are the simplest and convert best
  • Remove underperforming add-ons – If an add-on rarely gets selected, replace it with something more appealing
