How to Read Your Own Sales Data as a Supplement Brand
Revenue tells you how much you spent on marketing. Reorder rate tells you whether you have a business. A handful of numbers answer the questions that matter. Most dashboards report the ones that do not.
The Problem With Revenue
This guide is for supplement, Ayurvedic and herbal brand owners in India.
Revenue is the number everyone watches and the least informative one available. A brand can grow revenue every month purely by increasing marketing spend, while every customer buys once and never returns. That looks like growth and is a treadmill.
The question revenue cannot answer is whether the product works for the people buying it. Only repeat purchase answers that, which is why reorder rate deserves to be the primary number rather than a secondary one.
None of this requires sophisticated analytics. It requires looking at a few specific things consistently.
The Numbers That Matter
In priority order.
| Metric | What It Tells You |
|---|---|
| Reorder rate by SKU | Whether the product works for buyers |
| Time to reorder | Whether your pack duration and follow-up timing align |
| Contribution per order | What is left after product, packaging, shipping and payment costs |
| Acquisition cost by channel | What each channel actually costs per customer |
| Cohort retention | Whether retention is improving or just volume growing |
| Return rate by SKU and route | Product and logistics problems, separately |
| Stockout incidents | Revenue you never saw and customers you may have lost |
| Complaint rate by batch | Quality signals invisible in revenue |
| Average order value | Whether pack mix and bundling are working |
| Reorder rate by channel | Which channels bring buyers who stay |
Reorder rate by channel is the most underused of these. Channels differ in the quality of customer they bring, not only in cost per acquisition, and a cheaper channel bringing non-reordering buyers is more expensive than it looks.
Cohorts, Not Totals
This is the one analytical habit worth adopting.
Group customers by the month they first bought, and track what proportion of each group buys again at one month, three months and six months. That is a cohort view, and it separates two things a total cannot: whether retention is improving, and whether you are simply acquiring more people.
A brand whose revenue is rising while each successive cohort retains worse is in trouble that the revenue line conceals entirely. A brand whose cohorts retain better each month is improving even if revenue is flat.
This requires only order dates and customer identifiers, which you already have if you sell direct.
What to Do With Each Signal
Numbers are only useful if they change a decision.
Poor Reorder Rate
A product problem, not a marketing one. Investigate taste, format, expectations and usage guidance before increasing spend.
Good First Orders, Poor Reorders
Marketing is overpromising, or the product disappoints. Both are fixable, and scaling spend makes both worse.
Reorder Timing Drifting
Your pack duration and follow-up timing are misaligned. Adjust the follow-up schedule first, it is cheaper than changing the pack.
High Returns on One Route
A logistics problem, not a product one. Check the courier and the packaging, by route.
The distinction in the last two cards matters: product, marketing and logistics problems present similarly in aggregate numbers and need completely different responses.
Checklist
Set up a monthly review.
- Report reorder rate by SKU every month, alongside revenue.
- Track time to reorder against pack duration.
- Calculate contribution per order after all variable costs.
- Track acquisition cost and reorder rate by channel together.
- Build a simple cohort view by first-purchase month.
- Track return rate by SKU and by route separately.
- Log stockout incidents with dates.
- Track complaint rate by batch.
- Decide one action per review and record it.
- Check at the next review whether the action worked.
- Do not scale acquisition spend until reorder data supports it.

Frequently Asked Questions
Why is revenue a poor primary metric?
Because a brand can grow revenue every month purely by increasing marketing spend while every customer buys once and never returns. Revenue cannot tell you whether the product works for the people buying it; only repeat purchase can.
What should the primary metric be?
Reorder rate by SKU, reported monthly alongside revenue and used to govern decisions about scaling spend. A product with strong first orders and weak reorders has a product problem that more marketing will amplify rather than solve.
What is a cohort view and why bother?
Grouping customers by the month they first bought and tracking what proportion buy again at one, three and six months. It separates improving retention from simply acquiring more people, which a total figure conceals entirely.
Which metric is most underused?
Reorder rate by channel. Channels differ in the quality of customer they bring, not only cost per acquisition, so a cheaper channel delivering non-reordering buyers is more expensive than it appears.
How do I tell a product problem from a logistics one?
Break returns down by SKU and by route separately. Returns concentrated on one route are a logistics or packaging problem; returns spread across routes for one SKU point to the product, its expectations or its usage guidance.
