Stocklley replaces the spreadsheets, sticky notes, and disconnected apps most Amazon sellers stitch together. Replenishment, FBA & 3PL inventory, real accounting, and purchasing — under one roof, talking to each other automatically.
Most Amazon sellers run their operation across a spreadsheet, a separate inventory tracker, a bookkeeping app that doesn't talk to Amazon, and a notebook full of supplier notes. Stocklley folds all of it into a single login.
Days-of-stock, per SKU
One inventory ledger
Real double-entry books
Split across suppliers
No more eyeballing a spreadsheet to guess whether a SKU needs reordering this week or next month. Stocklley tracks real days-of-stock coverage per SKU and tells you the moment something needs attention.
FBA, Amazon Warehousing & Distribution, Amazon Logistics, and your own 3PL partners — Stocklley keeps sellable, inbound, and in-transit stock visible in one place, so you're never checking four different portals to answer "how much do I actually have."
Amazon's payout report isn't a set of books. Stocklley reconciles every settlement against a full double-entry ledger — chart of accounts, journal entries, P&L, balance sheet, cash flow — so what you see is what actually happened financially.
Split a SKU's production across multiple suppliers and Stocklley allocates purchase orders automatically, based on each supplier's share, lead time, and cost — no more manually splitting quantities in a spreadsheet before every reorder.
A promotion hits. A listing goes viral. A competitor runs out of stock and orders triple overnight. Most tools either overreact to every blip or smooth everything into a flat average that misses real demand shifts entirely.
Stocklley is built to tell the difference. It looks at your actual sales history month by month, recognizes genuine spikes versus one-off noise, and automatically excludes periods when a listing was out of stock — so a past stockout doesn't quietly drag down your forecast for months afterward. New listings are treated differently from established ones, so a slow first month right after launch never gets mistaken for weak demand.
The result: replenishment recommendations that reflect what your business is actually doing right now — not a generic average of the last twelve months.
Stocklley isn't another point solution to add to the pile. It's built to replace the general-purpose accounting software, inventory spreadsheets, and disconnected tools that weren't designed for how Amazon businesses actually operate.
Everything connected, automatically.
| The old way | With Stocklley |
|---|---|
| A spreadsheet guessing at reorder points | ✓ Automatic replenishment recommendations, per SKU |
| A separate tool just for FBA shipments | ✓ FBA + 3PL + AWD inventory in one ledger |
| Bookkeeping done after the fact, disconnected from Amazon | ✓ Real double-entry accounting, reconciled straight from Amazon payouts |
| Guessing which sales spikes were even real | ✓ Forecasting that tells real demand spikes from noise |
| Chasing suppliers and splitting POs by hand | ✓ Purchase planning across every supplier, automatically split |
| Four or five different logins to check on your business | ✓ One dashboard. Everything connected. |
Four more things Stocklley handles automatically so they stop being a weekly manual chore.
Stocklley scans every SKU's sales history and flags months that look like a stockout, not falling demand — a zero-unit month sitting between two months of real sales almost always means there was nothing to sell. It only starts looking after the SKU's Amazon listing actually went live, so pre-launch months never get miscounted.
Every SKU's sales history is broken down month by month, with seasonal uplift factors and category-level fallbacks calculated automatically — no spreadsheet of manual multipliers to maintain by hand.
Once stock is confirmed, Stocklley builds the shipment plan for you — box counts, unit totals, and Amazon-compliant manifests, ready before the truck arrives at the warehouse.
Track each shipment's status from created to received, with a full SKU- and ASIN-level breakdown of what's inside — no more opening several different Seller Central pages to answer "what's actually in transit."
Once stock lands, it flows straight into your FBA shipment plan — packed into Amazon-compliant shipments with manifests already formatted for US or UK requirements, ready to send. No manual box-count math, no re-keying numbers into Seller Central by hand.
Stocklley started as an operations backbone for Amazon sellers — inventory, replenishment, and real accounting in one place. We're now extending that same backbone into advertising performance and multi-channel selling. Here's what's actively on our roadmap:
Automated bid and keyword management for Sponsored Products and Sponsored Brands campaigns, so ad spend adjusts based on actual product-level profitability rather than click volume alone.
Real-time notifications when a listing's price, content, or Buy Box status changes unexpectedly, so sellers and their agencies can react before it affects sales.
Stocklley cross-references what you ordered, what FBA received, what sold, and what's currently in Amazon's warehouse to flag lost, damaged, or short-shipped inventory -- then drafts the case content for you to review. You submit every claim to Amazon yourself; Stocklley never submits a case on your behalf.
Upload your free Amazon Brand Analytics Search Terms report (exported from Seller Central -- no API access required) and Stocklley names the exact competitor products winning each of your search terms, with their click and conversion share, so you know who's beating you and by how much, not just that you're losing ground.
Upload your Amazon Warehousing and Distribution (AWD) Inventory report and see exactly what's Available in AWD, what's still Inbound, what's Reserved for FBA replenishment, and what's Outbound to FBA, per SKU, alongside the rest of your inventory -- so bulk upstream stock stops being a blind spot.
An installable, mobile-friendly version of the Stocklley dashboard for checking inventory and financial performance on the go — no app store download required.
Extending beyond Amazon to Shopify, Walmart, and eBay, so multi-channel sellers and agencies can manage inventory and finance from a single Stocklley account.

When a seller connects their Amazon account to Stocklley, we access only the data covered by the specific permissions ("roles") they approve during Amazon's authorization process — for example, order history, inventory levels, FBA shipment status, and Amazon settlement/payout reports. We never access an Amazon account that hasn't explicitly authorized Stocklley to do so.
Stocklley's core features — replenishment planning, inventory and shipment tracking, and financial reporting — do not require buyer-level personal information. We do not request or store customer names, shipping addresses, or other personally identifiable buyer information from Amazon, and we handle any Amazon data in line with Amazon's Data Protection Policy.
Amazon account credentials (refresh tokens) are encrypted at rest using AES-256-GCM and are never exposed to the browser or to any party outside Stocklley's own backend systems. All data is transmitted over encrypted (HTTPS/TLS) connections.
Data retrieved from a seller's Amazon account is used exclusively to power that seller's own dashboards, replenishment recommendations, and financial reports inside Stocklley. It is not sold, shared with advertisers, or used to train any product outside of the account it was retrieved for.

Infrastructure providers (such as our hosting and database providers) process data on our behalf solely to operate the service, under their own standard security and confidentiality commitments, and never access seller data for any independent purpose.
A seller may disconnect their Amazon account at any time, which stops all further data syncing. On request, we delete a seller's stored data within a reasonable timeframe, except where retention is required by law.
