Both put your Amazon data inside Claude, ChatGPT and Gemini. DataDoe sends the assistant 100+ normalized tables, refreshed daily, and leaves the arithmetic to the model. Nova sends it a P&L already reconciled to the cent, with orders and units arriving in real time, plus the Nova app and data sharing in the same package.

Verified 5-star reviews on Trustpilot and Reddit.
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.”
Exactly the kind of tool e-commerce needed
“Nova is exactly the kind of tool the e-commerce industry has needed for a while. Fast-moving, responsive, and adding value to every Amazon business at every turn. The team is always open to hearing feedback and new ideas.”
A great team to work with
“We had a great experience working with the Nova team. They were incredibly responsive, helpful and professional, and truly committed to improving the tool in ways that made it both simple and genuinely useful. It felt like they were invested in our success.”
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.”
Top notch customer support
“The team is genuinely responsive; they actually listen to concerns and implement suggestions into the tool, which is a big part of what makes it so powerful. The UI is clean and managing multiple accounts across marketplaces finally feels organized.”
A dependable solution for Amazon sellers
“We use Nova to manage and analyze our Amazon marketplace data across multiple accounts and regions. Clean interface, useful business insights, and strong visibility into KPIs. Support is proactive and continuous improvements keep landing. Highly recommended.”
Ashish Chaudhary
INA robust instrument with competitive pricing
“After a couple of months on Nova, the platform delivers outstanding value. As an agency managing a diverse portfolio of sellers, Nova made onboarding and overseeing multiple merchant accounts effortless. The data centralization streamlined our day-to-day.”
Pavel Zadorozhnyi
ESHighly 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.”

USNova has made tracking our Amazon profit easier
“Nova has made tracking our Amazon profit and performance so much easier. The near real-time data updates mean we're not stuck working off yesterday's numbers, and it's saved us a lot of manual spreadsheet work. Support has been quick and helpful whenever we've had questions.”
Mark Fleming
PTSophisticated tools, transparent data, and responsive support
“We partnered with Nova for our agency's performance reporting and it has been excellent. The platform is comprehensive and sophisticated without being overcomplicated, and we appreciate how accurate and transparent the underlying data sources are. Questions get answered quickly, even for custom requests.”

Reads: P&L lines, every fee and refund, per SKU and marketplace · Ads, search terms, Search Query Performance, inventory and BSR · Your cost inputs, so it can audit them
Writes: Cost of goods, FBM costs and VAT categories, inside Nova · Product tags, stock parameters and chart events, inside Nova · Nothing it writes acts on your Amazon account
Or start from the prompt library.
Orders and units reach Nova within seconds of the sale, with sales estimated until Amazon confirms the exact amounts. Ad spend refreshes every two hours, search term data three times a day, Amazon finance transactions hourly, and the remaining reports daily. DataDoe describes its layer as "100+ clean tables, refreshed daily", and separately lists Amazon Marketing Stream for real-time sales and ad events.
370 Amazon transaction lines map into 154 P&L lines. 187 appear in both the settlement report and the Finance API under different names, and double count unless reconciled. 183 exist only in the Finance API. Raw tables leave all of that to the model; Nova hands over the result, at 99.9% accuracy.
The same plan carries the Nova app (Cockpit, P&L, Inventory, Listings Health, Ads, Events tracker) plus Nova MCP, Nova Data Share and scheduled exports to Sheets, Excel, BigQuery and Snowflake. DataDoe offers MCP, REST and BigQuery: a data layer without an app. If raw tables in your own warehouse are the goal, DataDoe is built for that; Data Share covers the same need from the other direction.
See how the reconciliation works on the Amazon profit and loss dashboard, and every tool on the Amazon MCP server page.
Both connect through Amazon independently, so you can keep DataDoe while you compare.
Sign in with Seller Central, Vendor Central and Amazon Ads. Nova reads your data and loads your history.
Upload cost of goods as a spreadsheet once, or hand the file to your assistant to fill and preview.
Add Nova as a second connector in Claude or ChatGPT and compare the answers against the same settlement.
