Instead of sending a static quote or multiple, let clients pick and choose what they want right from the estimate.

Example: A mobile detailer sends an estimate with:

✅ Basic Wash – $100

✅ Interior Deep Clean – $250

🔲 Ceramic Coating – $200

✅ Full Exterior Detail (Wash, Wax, Polish) – $175

🔲 Seat & Carpet Shampoo – $125

The client selects what they want, and as they add more, they are incentivized with an automatic discount:

🔥 2 services = 5% off

🔥 3+ services = 10% off

Clients naturally upsell themselves, increasing both revenue and average purchase value. This would be a killer feature for all businesses that offer multiple services.
