Deep Amazon Integrations

Detailed Reporting

Intelligent Formulas Designed for Volume Sellers

Our formulas and automations are built by Amazon sellers, who deeply understand the nuances of Amazon FBA and FBM. Other software that treats Amazon data as “just another integration” may use flawed or incomplete core data, resulting in flawed formulas. We have seen this time and time again. Aspects like pending inbound shipments or units in FC transfer can dramatically impact replenishment. We sort these out and provide accurate insights. 

Strong Foundation

Accurate and Trustworthy Core Data

Accurate Amazon inventory management requires accurate core data, a critical fact that most software neglects (such as Stockouts), due to the complexity in gathering it from Amazon and using it properly.

We make sure the data you use for inventory decision-making is accurate and trustworthy. Even small differences in sales or inventory data can generate dramatic differences in replenishment numbers and timelines - costing money, time, and lost sales.



Help Mode

Teachable in 30 Minutes

The entirely unique Help Mode feature allows the user to hover over data points and read articles to learn more. This incredible feature brings clarity and understanding while using the software, which is proven to train more effectively.

Combined with the Unique Interface that displays deep data when you need it, without removing the user from their original position, One Page Inventory is the first inventory management tool that can be learned in 30 minutes.  

Warehouses Management System

Managing stock in a simple way

Amazon FBA replenishment requirements can be daunting to calculate and even more so when trying to consider inventory limits. One Page Inventory employs a replenishment formula that includes inventory limits, to help you stay in-stock and reduce lost sales. 

Amazon Inventory Management is

No Longer Complex!

Have you noticed FBA replenishment and management starting to take way too much of your time? Are you feeling frustrated by the lack of clarity in Seller Central or other software? You are not alone. Sellers from $1m to $100m annually still fight through this part of the business daily. 

When you have 10+ FBA products and/or sell in multiple marketplaces, the complexity of managing inventory becomes dramatically compounded. The seemingly basic questions of how much am I selling, when to replenish to FBA, how much to send, and how much to order from manufacturers remain complicated, not to mention stranded inventory and inventory limits. That’s because the data in Seller Central is scattered or non-existant, must be compiled manually, or other software that claims to manage Amazon inventory falls short.
