One Page Inventory is different
Features designed to help you gain inventory clarity quickly
The interface is unique, the way we display information is painstakingly debated, the formulas we use are actually accurate. Every feature is reimagined to genuinely help you grow your e-commerce, multi-channel business.

One-of-a-Kind Interface
The One Page Inventory interface is a combination of spreadsheet views and graphic visuals. It’s fast, it’s trustworthy, and everyone in your organization can use it. No longer do you need to “pull reports” for insight. It’s all there, right in front of you.
Views designed to mirror your thinking
SKUs are vertical, marketplaces are horizontal. The data is separate and aggregated. It’s fast because this is how you imagine it should be.
Deep data NOT deeply hidden
Additional information is always needed, and it’s available in popups instead of reports. Hover to see it then click away to come back.
Transparency that builds trust
Formulas are exposed to the surface and combined with visuals to help you understand, and trust, the proper handling of your inventory.
Accurate Sales by SKU
Sales velocity is core to accurate inventory management and marketplace replenishment, yet it can be difficult to accurately define. Our intelligent formulas analyze your velocity and adjust as needed, while our features are there to fine-tune to your particular business needs. All with elegant visuals.

Amazon-centric ASIN handling
Data buckets are specifically built to handle the complexity of Amazon. FBA/FBM switching, ASIN stacking, etc. are all accounted for accurately.
Aggregated sales across marketplaces
Marketplace sales are viewable separately as well as aggregated to build into “master” formulas like quantity to order from manufacturer.
Stockouts and other anomalies considered
Anomalies can make or break inventory management accuracy. OPI learns your particular sales situation over time and adjusts accordingly.

Beautiful and Clear Reporting
The OPI interface is a live report in itself, blending the typical static report with the ability to see updated data as it changes. When flat reports are needed, outputs for sales, inventory status, and other details are readily accessible.
See it in actionQuick send options for agencies
Managing multiple e-commerce clients is simple with our quick-send reporting features. One click and the client is in the know. Easy. Fast.
Live reporting within the interface
Other software is built to make you draw reports and compare data. Our data is comparable, sortable, and actionable right from the UI.
Beautiful reports that anyone can understand
Ever heard that a PDF inventory report is “beautiful?” Wait till you see ours! They are carefully designed and updated regularly.
Real-time notifications tailored to your needs
The alert feature allows you to create custom alerts for each marketplace based on the stock status or stock level of your products, enabling you to quickly react and manage your inventory more efficiently.
Comprehensive Inventory Breakdowns
Your current inventory levels form the basis of your inventory needs. OPI shows inventory breakdowns in marketplaces like Amazon where the total number may be misleading (think FC Processing), and carefully considers how to handle your inventory buckets.
Marketplaces are excluded to provide accurate numbers, such as in the case of distance selling from one country to another.
See it in action
Aggregated marketplaces and warehouses
Inventory quantities and breakdowns can be instantly viewed separately or as totals across all marketplaces and/or warehouses.
Amazon selling schemes considered
OPI handles schemes like distance selling from USA to Canada, or Pan-European/EFN. Without these options the numbers will simply be wrong.
Totals that build to PO placement
Easily choose which marketplace or warehouse inventory levels to consider when placing accurate POs with your manufacturers.
Track inventory movement
OPI provides real-time updates on inventory levels and movements, including FC Transfer and FC Processing, to ensure seamless tracking and efficient stock management.

Intuitive Sales Forecasting
Forecasting sales is important to properly order from your manufacturers, yet we found other tools make the process confusing and overly complex.
OPI simplifies forecasting by automatically aggregating your sales history and applying the right formulas to help you plan future demand. Our forecast tool is quick and easy to use, with descriptions behind every formula for clarity.
Fine-tuning on the fly
Easily adjust the Sales basis months (your normal sales periods) and watch the forecast change on the fly. Look… we made forecasting fun!
Aggregated forecast quantities
All sales channels for one SKU are combined together to understand what to order from your manufacturers and to plan future demand.
Batch forecast updating
Update numerous products in your catalog all at once with our batch forecast update feature. Less time clicking, more time growing.

Detailed Stockouts Handling
One Page Inventory exists to keep you in stock, but stockouts do sometimes happen. We automatically detect stockouts when they occur and offer a stockout selection feature to ensure your sales velocity and ordering formulas are as accurate as possible.
See it in actionQuick historical stockouts selection
Historical sales are displayed on a graph with the option to quickly select stockout periods and accurately affect sales velocity formulas.
Automatic daily stockouts detection
OPI uses a specific method to automatically differentiate between stockouts and no sales days and indicate them accordingly.
Trustworthy Sales Velocity
Careful tracking of stockouts is essential for a dependable sales velocity calculation, a detail-oriented approach that is reflected in OPI.
Clear Stock Status Visibility
Your dashboard provides clear visibility of stock status, allowing you to easily view overstocked, understocked, and sufficiently stocked items. This comprehensive overview ensures you can make informed decisions at a glance.
Manufacturer Ordering
Selling across multiple e-commerce channels means varying inventory levels and unique sales velocities. Add in warehouse in-stock quantities, manufacturer on-order, and pretty quickly you have a spider web of data to analyze. OPI tracks all of these data buckets separately and aggregates them into easily-digestible PO placement formulas that are accurate and trustworthy.

Timely Replenishment
OPI simplifies the often complex questions of what to replenish, when to replenish, and how much to send with ease. Crystal clear formulas and settings options combine with the unique OPI interface to offer actionable replenishment insights. All Amazon and other sales channels are segregated yet viewable together for complete 360° replenishment clarity.

Profitability, Fees, and COGS
Successful inventory management is often heavily intertwined with tight financial management. OPI calculates profitability using marketplace pricing, individual and aggregated fees, and cost of goods sold figures, exposing your true bottom line. The ability to batch update enables users to efficiently revise and manage pricing information across numerous items at once, ensuring accurate and up-to-date cost tracking.

Amazon fees exposed

Flags issues causing suppression, such as listing quality problems or compliance violations. This centralizes the information, allowing you to proactively address suppressed inventory efficiently before losing sales.
Recent Storage Type Change
Notifies you of changes in storage types, such as transitions from standard to oversized storage. This helps you monitor and manage the impact on your storage fees and inventory levels more effectively than tracking these changes across different Seller Central pages.
