Run your Amazon business
like an institution.

The Problem
You're running a data-rich business with data-poor tools. [COPY REVIEW]
Your spreadsheets lie to you.
Sellerboard shows you revenue. Amazon shows you fees. Nothing shows you the whole picture. Seller Calculus calculates true net margin per SKU — after COGS, FBA fees, ad spend, returns, LTSF charges, and storage. Every SKU. Every day.
Your tools don't talk to each other.
Inventory over here. Ad spend over there. Repricing in a third tab. When your tools don't share a data model, you spend your day reconciling instead of deciding. Seller Calculus is one platform where every module reads from the same source.
You're optimizing for yesterday's algorithm.
Search is shifting. Buyers are asking ChatGPT and Perplexity what to buy. Most Amazon sellers have no idea whether their products appear in LLM responses. Seller Calculus is the first platform that tracks and improves your AI visibility.
The Platform
11 modules. One source of truth.
Every module shares the same inventory, cost, and marketplace data model — so insights in one place immediately improve decisions in another.
Dashboard
Everything that matters, in one view.
Financial Module
True profitability. Not Amazon's math.
Sales Analytics
Velocity you can act on.
ROI Scoreboard
Rank every SKU by what it actually earns.
PO Builder
Purchase orders that build themselves.
Inventory Intelligence
Know what you have. Know what you need.
Repricer
Win the buy box. Protect your margins.
Advertising Optimizer
Every ad dollar accounted for.
AI Visibility Optimizer
The next search engine is an LLM.
Bundle Wizard
Turn slow movers into strong performers.
Recovery Engine
Don't leave money in Amazon's hands.
Why Seller Calculus
Three things no other platform does.
AI Visibility Optimization
The next 5 years of product discovery happens in LLMs.
ChatGPT, Claude, and Perplexity are already answering "what's the best [product] for [use case]?" Your competitors don't know whether they appear in those answers. You will. Seller Calculus is the first operational platform to track and optimize AI visibility alongside your Amazon metrics.

About AVO →Lender-Grade Collateral Valuation
Know what your inventory is worth to the people writing the checks.
Asset-based lenders use recovery rate models and liquidation scenarios to underwrite inventory loans. That same engine — OLV, FLV, borrowing base, concentration risk — lives in your Seller Calculus dashboard. Whether you're raising a credit line or planning a liquidation, you're working from the same math your lender uses.

About Recovery Engine →Real Operating DNA
Built inside real Amazon businesses, not a VC whiteboard.
Seller Calculus is built and tested by operators running mid-seven to eight-figure Amazon catalogs. Every feature exists because we needed it ourselves — not because a product team thought it would be a good idea. That means the edge cases are already handled, the data model reflects how real catalogs work, and the roadmap is driven by what operators actually face.

We ingest, score, and surface.
Seller Calculus pulls inventory, velocity, buy box data, fees, ad spend, and order history. Every SKU gets a fragility score, days of supply, and true net margin. Reorder recommendations update daily. You stop guessing.
[COPY REVIEW]
You make better decisions, faster.
Approve a reorder in the PO Builder. Chase a buy box with one click. See which campaigns are funding the business and which are burning it. Know what your inventory is worth to a lender before they ask. The platform does the math. You do the deciding.
