How do I track Subscribe & Save performance on Amazon?
Amazon exposes three Subscribe & Save data points: total S&S sales, S&S as a percentage of total sales, and active subscriber count per SKU. Nova surfaces all three at the SKU level so you can see which products build subscriber momentum and which lose subscribers month over month.

The three metrics Amazon exposes
S&S sales (revenue from Subscribe & Save orders), S&S share (S&S sales as a percentage of total sales for the SKU), and active subscriber count (number of shoppers currently subscribed to that SKU).
What good looks like
Consumable SKUs (supplements, coffee, household) often reach 30% to 50% S&S share within 12 months of enrollment. Non-consumables rarely cross 5%. Rising subscriber count month over month is the leading indicator of stable long-term revenue.
Programme mechanics
S&S offers 5% off single-item subscriptions, 15% off when a shopper has 5+ subscription items shipping the same month. Sellers fund the discount. The programme is opt-in per SKU.
Frequently asked questions
Does Nova cover Subscribe & Save?
Yes, for the three data points Amazon exposes: S&S sales, S&S percentage of sales, and active subscribers per SKU.
Can I see individual subscriber IDs?
No. Amazon does not share subscriber-level identity.
What happens when a subscriber cancels?
Amazon does not notify you individually; the active subscriber count drops in the next report.
Is S&S worth the discount?
In consumables usually yes, because subscribers stabilise BSR and improve forecasting. In one-time-purchase categories, less compelling.

How do I track profit at the SKU level on Amazon?
SKU-level profit requires matching every revenue and cost line to the SKU that generated it. That means pulling settlement reports, product-level ad spend, refunds, storage allocation, and COGS, then attributing each. Doing this manually in Excel takes 4 to 8 hours per month per account; automated tools reduce it to a dashboard view.
What is a good net profit margin on Amazon FBA?
A healthy Amazon FBA net profit margin sits between 15% and 25% after fees, COGS, PPC, and refunds. Under 10% usually signals hidden fees or overspending on ads. Established brands with private-label pricing power can hold 25% or more, while resellers and wholesalers typically operate closer to 10% to 15%.
What is the Amazon Sales and Traffic report?
The Sales and Traffic report (Seller Central > Reports > Business Reports > Sales and Traffic by ASIN) shows daily orders, sessions, page views, unit session percentage, and buy box percentage per ASIN. It is the single most useful free report for diagnosing conversion and traffic problems.
