An Operating System for Complex Amazon Operations
Marketplace OS brings purchasing, inventory, sales, profitability and management reporting into one structured operating environment built around the way your Amazon business actually works.
When Spreadsheets Stop Being Enough
Amazon businesses often grow by adding spreadsheets, reports and manual processes one at a time. Eventually, the information exists — but it no longer forms a reliable operating picture.
Common Signs of Operational Fragmentation
- Purchase orders tracked separately from inventory
- Supplier invoices disconnected from product cost
- FBA inventory not reconciled with inbound stock
- Profitability calculated differently by different people
- Management reports rebuilt manually every month
- Missing costs discovered only after decisions are made
- No clear view of what requires action today
Marketplace OS is designed to connect these workflows rather than create another isolated reporting tool.
Not Another Generic Dashboard
Marketplace OS is a configurable operating environment designed around Amazon workflows, financial controls and internal business processes.
Business-Model Fit
Wholesale, private label and mixed operating models require different purchasing, inventory and reporting logic.
Workflow Fit
Supplier, prep-center, FBA, approval and internal responsibility flows can be structured around the business.
Financial Logic
Costing, profitability and management reporting are designed around the data the operation actually needs.
The system follows the operating model of the business — the business does not need to reorganize itself around generic software.
Purchasing and Supplier Visibility
Know what was ordered, what has been paid, what is in transit and what is still missing.
Suppliers
Supplier records, commercial terms and purchasing history.
Purchase Orders
SKU quantities, invoice values, payment status and expected arrivals.
Shipment Status
Track purchase progress through supplier, transit and prep-center stages.
Purchase History
Review past orders and purchasing decisions in one operating context.
Inventory Across the Entire Flow
Inventory should be visible before Amazon receives it — not only after it becomes FBA inventory.
Ordered
Inventory committed on supplier purchase orders.
In Transit
Units moving between supplier, carrier and prep stages.
Prep Center
Inventory received or awaiting preparation before Amazon.
Inbound to Amazon
Units assigned to Amazon inbound shipments.
FBA Available
Sellable inventory already available in fulfillment centers.
Stock Coverage
Estimate how long current and inbound stock can support demand.
Reorder Control
Use lead time, demand and safety stock to identify replenishment needs.
Inventory Age
Surface slow-moving and aging inventory before it becomes a larger cost.
Exceptions
Identify stockouts, overstocks and inventory discrepancies that need attention.
Know the Complete Cost of Every Product
Reliable profitability starts with reliable cost data.
Marketplace OS can structure product purchase cost, freight, prep, duties where applicable and other landed-cost adjustments according to the business's costing approach.
Product Cost Can Include
- Product purchase cost
- Freight and inbound transportation
- Prep-center charges
- Duties or other landed costs where applicable
- Cost adjustments and allocations
Sales Performance in Operational Context
Sales data becomes more useful when it is connected to purchasing, cost and inventory rather than viewed in isolation.
Revenue & Units
Sales and unit movement by period and SKU.
Amazon Fees
Marketplace and fulfillment charges connected to product economics.
Refunds & Returns
Visibility into the impact of refunds and returns on performance.
Comparisons
Review product and period performance against prior results.
From Revenue to Contribution Profit
A revenue report is not enough when management needs to understand what each product actually earns.
Selling Revenue
− Amazon Fees
− COGS
− Prep
− Freight
− Other Allocated Costs
= Contribution Profit
Operational Finance Visibility
Connect supplier payments and product costs to the operational decisions they support.
- Supplier prepayments and outstanding balances
- Purchase-related payments
- Cost allocation
- Basic operational ledger structure
- Accounting export or handoff
- Management reconciliation
Accounting Boundary
Marketplace OS supports operational financial control and management reporting. Statutory accounting remains within the company's accounting system and professional accounting process.
Know What Requires Attention
Exception-based controls reduce the need to manually inspect multiple files every day.
Low stock
Flag the exception for review instead of waiting for it to surface in a later report.
Missing product cost
Flag the exception for review instead of waiting for it to surface in a later report.
Negative or low margin
Flag the exception for review instead of waiting for it to surface in a later report.
Late supplier delivery
Flag the exception for review instead of waiting for it to surface in a later report.
PO without invoice
Flag the exception for review instead of waiting for it to surface in a later report.
Inbound shipment delay
Flag the exception for review instead of waiting for it to surface in a later report.
Product without mapped SKU
Flag the exception for review instead of waiting for it to surface in a later report.
Inventory discrepancy
Flag the exception for review instead of waiting for it to surface in a later report.
Built Around Your Existing Workflow
Marketplace OS is implemented around the real operating process rather than deployed as a one-size-fits-all package.
Process Mapping
Understand how purchasing, inventory, costs and reporting work today.
Data Mapping
Identify Amazon exports/API data, supplier files and internal spreadsheets.
Configuration
Set statuses, calculations, controls and management structures.
Migration
Bring across the master data and opening information needed to operate.
Adoption
Define daily workflows and train the people responsible for execution.
Improvement
Add automation and additional capabilities as operational complexity grows.
Best Suited For
- Amazon wholesale businesses with multiple suppliers
- Sellers managing meaningful inbound inventory
- Businesses where purchasing and Amazon data are disconnected
- Teams building management reports manually
- Sellers unable to calculate reliable product-level profitability
- Businesses that have outgrown spreadsheet-based operations
Use the Simplest System That Works
For a small seller with a simple catalog, a well-designed spreadsheet may still be the right solution. We recommend systems only when operational complexity justifies them.
Software Should Follow the Operation
Some businesses need stronger purchasing controls. Others need profitability, inventory or accounting visibility first.
Marketplace OS can be implemented in stages rather than requiring a full system rollout from day one.
Technology Backed by Operational Understanding
We do not separate system design from the business process it is meant to support.
Marketplace OS projects combine Amazon operations, financial logic and workflow design so the system supports real decisions and responsibilities.
