New product launch tracking: the first 90 days

New product launch tracking means watching three things in sequence: whether stores start carrying the item, how fast it sells in the stores that do, and whether it keeps selling once the novelty wears off. Most bad launch reads come from blurring those three questions into one sales number.

The order matters. In the first month, total sales mostly measure distribution. In the second, velocity takes over. Only near the end of the window does repeat behavior start to show. A methodical read follows that sequence and resists the urge to skip ahead.

Days 1 to 30: watch distribution, not sales

A chain launch can put a product into thousands of stores in a single week. Independent retail doesn't work that way. Each store owner decides on their own, often across the counter from a distributor rep or on a wholesale run, so distribution builds one decision at a time.

That's why early totals are a supply story. If dollars double in week three, the likely cause is more stores stocking the item, not more shoppers wanting it. The number to track is the count of stores scanning the product each week. Point-of-sale (POS) scan data, the record of items rung up at the register, shows the exact week each store sells its first unit.

Rising store counts with modest per-store sales is a normal first month. A flat store count is the early warning worth acting on, because everything downstream depends on getting to shelf.

What does velocity tell you that total sales can't?

Velocity is the rate of sale in stores that carry the item, usually expressed as units per store per week. It separates "the product is spreading" from "the product is selling."

From roughly day 30 to day 60, velocity is the headline number. Compare the new item against an established product in the same category at a similar price and pack size. A new single-serve drink should be read against other single-serve drinks, not against a category average that mixes in multipacks and slow specialty items.

One caution: early velocity flatters. The first stores to take a new item tend to be the best-run stores with the most curious buyers, and their shoppers see the product first. Expect some cooling as distribution widens into more typical stores. That's settling, not failure.

When is it too early to call a launch?

Before day 60, almost always. First-month buyers include a lot of one-time triers, and trial says little about month six. The evidence you want is continuity: stores that keep scanning the item week after week are reordering it on purpose, and shoppers are giving them a reason to.

By weeks 8 through 13, focus on the earliest stores to stock the product. If velocity there is holding or settling at a workable level, the item has found a base. If it slides week over week while newly added stores prop up the total, the total is hiding the problem.

A 90-day checkpoint list

1. Day 30: is the count of stores selling the item still climbing? If not, the issue is distribution, and no amount of shopper marketing fixes an empty shelf.
2. Day 45: how does velocity compare against a fair benchmark item at a similar price and pack?
3. Day 60: in the earliest stores, is velocity holding, settling, or sliding?
4. Day 90: put the three reads together and pick a path: widen distribution, fix price or pack, or wind the item down before trade spend piles up.

The independent channel is a useful place to run this kind of read. NRS Insights works from POS scan data collected across a network of independent retailers running the NRS point-of-sale system, so a small-format launch is visible store by store and week by week, and the monthly same-store sales report shows how the wider channel moved while your launch was in market.
