Thinking about moving from sparkling water into functional energy? Or maybe RTD cocktails? Before you cut the PO for new cans, you need to look at three very specific numbers:

1. Incremental vs. Cannibalistic Growth: Does this new drink bring in a new customer, or does it just steal a sale from your original SKU? Look at "Basket Data." If your target customer is already buying a competitor's energy drink alongside your water, your expansion is Incremental. If they're just swapping one of your bottles for another, you're just cannibalizing your own margin.
2. Retailer Gap Analysis: Don't just offer "another choice." Offer an "answer." Check the scan data to see where the category is underperforming. If your competitors have a 20% "out-of-stock" rate on weekends, or if "Low Sugar" is growing 2x faster than the rest of the aisle, that’s your entry point.
3. Lead-Time Stress Testing: New categories often mean new co-packers. If your logistics can't handle a 50% spike in demand during the first month, you'll "burn" your credibility with the retailer on day one. Calculate your Days on Hand (DOH) before the first pallet leaves.
