Limonene: Built for Amazon Selling Partners
Catch Stockout Losses
Velocity-aware alerts the moment a fast-moving SKU runs out, with one-click price adjustments capped at the 20% Selling Partner API policy limit to slow demand while you restock.
Claim Reimbursements
We detect every EGP, SAR, or AED the warehouse owes you for damaged, lost, or missing inventory by reading your Financial Events ledger. Most sellers leave thousands unclaimed.
Account Health, Explained
Amazon's own performance checklist and policy-violation flags, translated into plain language — silent when your account is clean. Read buyer message threads on shipped orders without leaving the dashboard.
Services Offered
Limonene, the account management and analytics product built and operated by Zed Axis, connects to a seller's Amazon account through the official Selling Partner API, with the seller's authorization, and delivers the following core services:
Inventory Management
Automated tracking of stock levels with out-of-stock and low-stock alerts, restock-timing guidance, and identification of slow-moving and unsellable inventory — so sellers prevent lost sales and reduce storage costs.
Financial Reporting & Reconciliation
Audits the seller's financial events to detect unclaimed reimbursements for damaged, lost, or missing warehouse inventory, and reports real net profit and margin per product — giving sellers clear visibility into their bottom line.
Pricing Management
Monitors competitive and Buy Box pricing and applies seller-approved price adjustments, capped at Amazon's pricing-automation policy limit, to help sellers stay competitive and protect margin.
Buyer-Seller Messaging
Read access to buyer-seller message threads on shipped orders, so sellers can manage customer questions without leaving the dashboard.
Tax & Invoicing
Generates per-order tax invoices (Arabic and English) compliant with Egyptian VAT requirements, so sellers meet their local regulatory obligations.
Account Health & Alerts
Consolidates the issues that need attention into one dashboard and sends real-time notifications for critical events, so sellers can act before small problems become costly ones.
Core Offerings, Benefits & Expertise
Zed Axis Systems LLC is an e-commerce software company. Its product, Limonene, is a secure, policy-compliant automation tool purpose-built for Amazon sellers. The service is built and operated first-hand by an active Amazon.eg seller, so every feature solves a problem that a real seller faces daily. The benefit to our clients is simple: less time spent reconciling spreadsheets and switching between Seller Central tabs, and more captured revenue — recovered reimbursements, prevented stockouts, and protected margin — all from a single dashboard with full Arabic and English support.
How Limonene Works
Limonene connects to your Selling Partner account via the Amazon SP-API with the roles you authorize. Every 30 minutes a small set of generators reads inventory, pricing, and financial event data and produces a short list of actionable insights. Each insight can be resolved either by opening the right Seller Central page pre-filled, or by executing a compliant action through the API with a confirmation click.
1. Stockout detection
Fulfillable inventory hits zero on any SKU you're actively investing in (positive recent sales velocity OR an inbound shipment in transit). Severity grades by signal strength: actively selling with nothing on the way is critical, selling with restock incoming is warning, new listing with restock incoming is info. Zombie listings with no signal stay quiet so the dashboard doesn't drown in noise.
2. Running-out warnings
Stock will not survive your configured lead time (default 30 days). Includes a Raise Price action capped at the 20 percent Amazon AI Agent Policy limit to slow demand while you restock. Velocity divides by in-stock days, not the full window, so SKUs that were OOS most of the period don't get understated.
3. Buy Box loss
For SKUs with competition where another seller owns the Buy Box. Shows the gap percentage and the competitor's price. One-click Match Buy Box undercuts their price by 0.01 within your configured floor.
4. Reimbursement detection
We paginate listFinancialEvents over the last 180 days and aggregate AdjustmentEventList entries matching MISSING_FROM_INBOUND, WAREHOUSE_DAMAGED, WAREHOUSE_LOST, FBA_INVENTORY_RECONCILIATION, and related codes. Each insight surfaces the SKU, exact amount in EGP/SAR/AED, and the posted date so you can correlate to the right shipment.
5. Damaged inventory
Unfulfillable quantity greater than zero on any SKU. One-click Remove action submits a removal order through the Feeds API. Severity reflects the storage-fee impact.
6. Reorder planning
A velocity-aware, trend-adjusted order-by date and suggested reorder quantity for every SKU, built from your actual sales pace and your configured lead time, so you order the right amount at the right time instead of guessing.
7. Account health, in plain language
Surfaces Amazon's own performance checklist and policy-violation flags and explains what each one means in plain English or Arabic. Stays silent when your account is clean.
Safety architecture
Every executor that writes to Amazon requires a two-step confirm. On the live seller view a red LIVE pill appears on the confirm card so the action's intent is unmistakable. The Settings page exposes a master kill switch that halts the insight engine, repricer, auto-review worker, and inventory snapshot worker within one cycle. A full audit log records every write, visible to the seller in Settings.
