Your profit number comes from Amazon’s data, not estimates
Every payout report is processed automatically – sales, refunds, returns, fees, and adjustments each handled separately. What you see on your dashboard is what Amazon’s records say.
Every sale, fee, and reimbursement gets reconciled against your real cost of goods – so you know exactly what each product, supplier, and category is earning. Broken down the way you buy and sell, in accounting-ready numbers you can actually act on.
Trusted by 10,000+ sellers
From reconciled payout data to per-SKU profit, reimbursements, and accounting-ready reports – everything you need to run your reselling business on real numbers.
Every payout report is processed automatically – sales, refunds, returns, fees, and adjustments each handled separately. What you see on your dashboard is what Amazon’s records say.
See which products, suppliers, and categories earn their keep – built on reconciled payout data, not estimates.
Per-SKU P&L, summary roll-ups, and CSV export up to 100K rows. What you see on the dashboard is what goes in the report.
Returns, removals, and replacements flow into your P&L as separate line items. Money Amazon owes you shows up on your books – not buried in a report you have to go looking for.
Every payout report Amazon sends gets processed automatically. Sales, refunds, returns, fees, and adjustments are each handled separately – so nothing gets missed and nothing gets estimated.
Get Financial Clarity Get Financial ClarityMost dashboards show you what you made across your whole account. InventoryLab Accounting shows you what you made on each product, each supplier, and each category, so you know where to buy more and what to cut.
See the true margin on every SKU after every fee and every cost. Know which products are worth reordering and which ones are quietly losing you money.
See which suppliers are actually profitable and which aren’t, based on real margin data – not just order volume.
See which parts of your catalogue are pulling their weight and which are dragging your margins down. Cut with confidence, double down where it counts.
InventoryLab Accounting tracks returns, removals, replacements, and reimbursements as separate data streams, so they show up on your books as actual recoverable money.
Optimize Your P&L Optimize Your P&LP&L statements built from reconciled data, exportable in formats that work outside the dashboard – for your own records, your bookkeeper, or your tax prep.
Whether you’re flipping arbitrage finds, managing supplier relationships, or running a multi-channel operation – InventoryLab Accounting is built around the financial concerns that come with buying and reselling, not just selling.

Every flip tracked to its true margin, fee by fee.
You’re buying from dozens of sources and selling across hundreds of SKUs. InventoryLab Accounting tracks the cost of every unit against what Amazon actually paid you for it – so you know which flips are worth repeating and which ones to leave on the shelf.

Supplier-level profit visibility, not just product-level.
You have supplier relationships to manage and catalogs to evaluate. Per-supplier and per-category P&L reports show you which relationships are earning their keep – built on reconciled payout data, not estimates.

One profit picture across every channel you sell on.
FBA, merchant-fulfilled, and unlisted inventory tracked in one place. As your operation grows, your financial reporting grows with it – without the spreadsheet reconstruction job at the end of every month.
“[InventoryLab] is the cheapest and most useful subscription I have. Even just one of the pieces, be it Scoutify, List & Prep, or Accounting, alone would be more than worth the low cost.”
Seller 365 connects every stage of your reselling operation – from finding products to shipping them to knowing exactly what you made. InventoryLab Accounting sits at the profit management stage, where your numbers finally come together.

The full Seller 365 suite has seriously streamlined my workflow — repricing is automated, listing is easy, and my average selling price has gone up 7%.
I really love the all-in-one package of programs, which makes Amazon selling so much simpler. Thank you Threecolts!
Since discovering Tactical Arbitrage and InventoryLab, now part of the Seller 365 bundle, our Amazon business has completely transformed.
The platform took me from logging into 4 different vendors to one website which made life a ton easier.
Tactical Arbitrage AI matching is absolutely amazing. Helped me a lot to grow my Amazon business. Unrivalled accuracy and a plethora of tools to help sellers.
The team at Threecolts are really knowledgeable and set me up brilliantly. Do not hesitate to begin a subscription.
I love the new update where you’ve combined a bunch of softwares for the price of 1. This is ultimately a game changer in the industry.
We found that Seller 365 was way better and faster than our in-house team.
Inventory Lab helps us keep clear track of our P&L, inventory levels, and creating Amazon shipments. Tactical Arbitrage saves us so much time with sourcing.
Normally things we do without this application would take a lot of hours, but it speeds up the process perfectly.
I’ve had a great experience with all their tools since 2019. I used to pay a few hundred dollars before the Seller 365 bundle came out, and now it’s a no brainer.
Inventory Lab was a great tool for keeping track of all things Amazon. If I ever dive back into selling on Amazon, you guys will be my first stop!
Threecolts has a fantastic collection of industry-leading resources for Amazon sellers. Their team understands Amazon — they adapt to the needs of sellers.
We have the top 365 package. We love how the team listens and helps solve problems. Everyone has been so professional and polite.
The suite of tools has significantly streamlined our processes. Since integrating Threecolts, we’ve seen a noticeable boost in productivity and profitability.
It has a simple and useful interface. Simple to learn, user friendly. It makes the work more fluent by making connections with Amazon.
I’ve used many similar software products, and this one is truly my favorite. So well done, good user experience, great training materials, quick and thoughtful customer service.
I was surprised to see what Inventory Lab has become. It is now a suite of softwares that offer more value than the individual softwares I have been using.
