## Step-by-Step Local In-Browser Workflow
1. **Import Post-Purchase Funnel CSV or Load an Upsell Preset**: Enter monthly checkout volume, Upsell 1 & Downsell 2 offer prices, discount depths, unit COGS, 3PL extra-pick fee, and parcel weight step-up cost.
2. **Tune Upsell Attach Rate, Offer Discount & Shipping Jump Sliders**: Simulate 8% to 22% one-click accept rates and see how second-charge Stripe fixed fees ($0.30) and 1lb+ parcel weight jumps affect true net profit per order.
3. **Export Optimal Upsell SKU Selection & Net Contribution Ledger**: Identify which lightweight, high-margin SKUs belong in your post-purchase funnel and eliminate heavy upsells that trigger shipping losses.

## Frequently Asked Questions (Direct Citation Q&A)
### Q: Why does a post-purchase one-click upsell often have a much lower net margin than an in-cart upsell?
A: Two hidden costs hit post-purchase one-click offers: 1) Because the initial order was already authorized at checkout, accepting the post-purchase offer typically processes as a second separate credit card transaction—incurring a second $0.30 fixed gateway fee; 2) Post-purchase offers usually require a 20%–35% impulse discount while still adding 3PL extra-pick labor and parcel weight.

### Q: How can adding a post-purchase upsell item trigger a $3.50+ shipping cost spike?
A: USPS Ground Advantage offers low sub-1lb ounce rates up to 15.99 oz. If a customer's original order weighs 13 oz and they click 'Add to Order' on an 8 oz upsell item, the merged shipment now weighs 21 oz—jumping into the 2 lb zone rate and costing $3.20 to $4.50 more in postage even though the customer wasn't charged extra shipping.

### Q: What types of SKUs generate the highest net profit in a post-purchase one-click funnel?
A: Lightweight, compact consumables ( under 3 oz, such as refill pouches, serums, travel sachets, or small accessories) and zero-weight digital/service add-ons (extended 2-year warranties, priority fulfillment, VIP memberships) deliver 70%–86% net margins because they never push the parcel into a heavier shipping tier.

### Q: How much do upsell app revenue-share fees actually take from my net profit?
A: A '1.5% of upsell revenue' app fee sounds small on gross revenue, but if your post-discount, post-shipping net margin on a heavy upsell is only 15%, that 1.5% gross fee actually takes 10% of your net profit on top of the $99/mo subscription.

### Q: Does OneClickROI Studio connect to our Shopify checkout or upload customer data?
A: Never. All funnel simulations, parcel weight jump checks, and CSV exports run 100% locally inside your browser. Zero store or customer data ever leaves your computer.

### Q: How does the $19 one-time buyout work?
A: You get lifetime access to OneClickROI Studio for a single $19 buyout (or €3.99 for a 24-hour audit pass) with zero monthly subscription fees and a 14-day refund guarantee.
