Fantastic data share for Amazon agencies

“Nova has become a core part of how we run our Amazon agency. Data Share puts clean, structured Amazon data straight into our own stack, so we no longer maintain those pipelines ourselves. The hourly updates mean we spot changes during the day instead of managing accounts on yesterday's data.”

The P&L view captures everything Amazon-related

“The P&L view is the big one. It captures everything Amazon-related with the granularity to track down every unexpected expense, giving me a real profit statement I can run the business off of. No more guessing margins or waiting for end-of-month reconciliation.”

Just go for it. You won't regret it

“The Nova team has built something truly special. The days of clunky Looker Studio dashboards are over. They are communicative and collaborative, and work hard to make the platform as helpful as possible for their users.”

Nova is great

“Nova keeps us up to date across all of our client accounts and provides a unique set of analytics. The data is live, which lets us make quick decisions faster than with other tools. The events feature is excellent for logging listing changes and running lift tests.”

Replaced hours of reporting with one dashboard

“I manage multiple brands and Cockpit, P&L and Day-to-Day are now part of my daily workflow. What used to take hours across multiple tools I now see in one place. Antoine and Maxime are clearly building this with real seller challenges in mind, and they listen.”

Highly recommended

“Running an agency that manages a large portfolio of Amazon brands, what we value most is the people. Nova has been a real partner from day one, adapting to how we work. Multi-store management sits in one clean place and the team actually listens to feedback.”

Nova has made tracking our Amazon profit easier

How Nova forecasts your stock and flags the next restock

  1. Demand
Demand

Nova calculates your sales velocity

Daily units sold over the last 30 days, with recent days counting more. Every days-of-stock number that follows divides by it.

Last 7 days, 54% of the weightYesterday, weight 1A week ago, 0.53A month ago, 0.05
Each day weighs 0.9 times the day after it, so a real shift in demand shows up within days while one spike does not rewrite the month.
  1. At Amazon
At Amazon now

Then compares it to what you can actually sell

Every stock location in one table. Reserved units are already sold, so they do not count. Switch on Include FBM and your own stock counts too.

  1. Sellable is available plus FC transfer
  2. FBM available, counted when Include FBM is on
  1. Inbound
On the way

Next, Nova adds what is already on the way

What is shipped, what is still planned, and which shipments Amazon closed short, so your cover counts the units you will really receive.

Inbound FBA shipments view with on the way, units inbound, planned, closed incomplete and units missing totals, and a table of shipments with destination fulfilment centre, status and percentage received
  1. AWD
Upstream at Amazon

Your AWD stock, included

AWD stock and units inbound to AWD get their own days of stock, and reorder targets count FBA plus AWD.

Your 3PL stock and open purchase orders count too. Set four parameters and Nova gives you the quantity, rounded to your case pack, and the date to order by.

Which products are worth restocking at all sits in the per-SKU profit and loss, next to the FBA storage fee the cover you are about to buy will pay.
