How to Add Optional Add-Ons to an Estimate

2 min readUpdated Apr 27, 2026

After reading this, you will know how to offer add-ons on an estimate without inflating the headline price. Rundo lets you mark any line item as optional. The customer sees a checkbox next to each one when they review the estimate, and they pick what they want.

1

Open or create the estimate

Go to Estimates and either click New Estimate or open the draft you want to edit.

2

Add all your line items

Add every item you want to offer, both must-haves and add-ons. Use the same line item editor for all of them.

3

Click Mark optional on add-ons

Below each line item, click the small + Mark optional button. The row gets a soft background tint and an OPTIONAL label appears.

4

Review the totals card

The Total at the bottom of the editor shows only the required items. A separate Plus add-ons line shows the maximum the customer could add if they accept everything.

5

Send the estimate

Click Send. The customer email shows your required items in the main table and a callout below the total telling them how many add-ons are available.

Pro tip

Use optional items for upsell-friendly extras like extended warranties, premium materials, or extra cleanup. Keep the must-haves required so the base price the customer sees in their inbox is what you actually need to do the job.
