InventoryLab

The fastest way to get sourced inventory listed on Amazon

Plan your buys, build your shipments, manage your stock, and know your true profit – all on the same data.

Start Free Trial Start Free Trial Explore Plans Explore Plans

Trusted by 10,000+ sellers

InventoryLab dashboard showing the listing and shipment workflow
How it works

Everything your operation needs, built into one platform

From margin calculations to shipments, profit tracking to inventory. All running on the same data.

Margin visibility

See your real profit before anything goes in the buy list. Every Amazon fee – referral, FBA, storage, peak surcharges – calculated upfront so you know exactly what you’re making before you commit.

Shipment workflow

From buy list to box label without touching Seller Central. Manage MSKU generation, inbound plans, and box content labels in a five-stage guided process.

InventoryLab By product
Profit & loss May 2026
Sales $24,180.00
Amazon referral fees −$3,627.00
Amazon FBA fees −$2,418.00
Storage fees −$486.20
Advertising −$1,210.00
Buy cost −$10,432.00
Net profit $6,006.80

Built-in P&L

See what you’re actually making – by product, supplier, or category. These are your day-to-day profit numbers.

Unified inventory

All your stock in one place. FBA, merchant-fulfilled, and unlisted inventory tracked together, all on the same underlying records as your shipments and profit data.

FBA shipments

There’s a faster way to get inventory into FBA

InventoryLab replaces the whole Seller Central shipment process with a guided workflow that gets inventory out the door faster and with fewer errors.

Before InventoryLab

Tedious, error-prone, and slow, every single time.

  • Multiple screens, one shipment Jumping between tabs just to create a single inbound plan.
  • Manual MSKU creation One wrong entry and your inventory lands in the wrong place.
  • Box contents guesswork No structured process means labels get missed and shipments get flagged.
  • Errors you find too late Mistakes surface at the warehouse, not at your desk.
With InventoryLab

Every step guided, nothing missed.

  • Find it Scan or search any product and see your real profit before it goes in the buy list.
  • Plan it Build your shipment, create your inbound plan, and auto-generate MSKUs — all without opening Seller Central.
  • Box it Box content labels generated automatically. No manual entry, no missed requirements.
  • Ship it Inbound plan sent directly to Amazon. Track the shipment from dispatch to delivered.
Ship Faster Ship Faster
Your data stays connected

One record, carried through every stage – nothing gets lost between them.

Most sellers run multiple tools that never quite talk to each other. InventoryLab starts with one record and carries it through every stage. From the first buy decision to the final settlement – it’s all the same data.

Profit you can trust

Know exactly what you’re making – before you buy and after you sell.

InventoryLab models every fee at the unit level so your profit number is accurate from the moment you list to the moment Amazon settles.

Tier-based FBA fee modelling. Peak rates, non-peak rates, variable closing fees, lithium battery surcharges, and storage — all calculated at the unit level.

Automated reconciliation. Every fee, refund, and adjustment from your Amazon settlements processed automatically.

Multi-dimensional P&L. Your profit by SKU, ASIN, supplier, category, or fulfilment channel — same numbers, every lens.

InventoryLab works for where you are right now.

Whether you’re just starting out or running a serious volume operation, the workflow scales with you.

Get StartedGet Started

New reseller

Getting started with FBA means learning a lot at once.

InventoryLab gives you a guided shipment workflow, automatic fee calculations, and a P&L that tells you what you’re actually making, so you’re not piecing it together from spreadsheets on day one.

Experienced reseller

You’ve outgrown the spreadsheet and need something more robust.

InventoryLab handles your sourcing decisions, FBA shipments, and multi-dimensional P&L in one place, so you stop switching between apps and start trusting your numbers.

Wholesale

Volume means supplier margins, reorder timing, and per-unit accuracy matter more.

InventoryLab tracks P&L by supplier, models fees at unit level, and keeps replenishment on schedule. Prep centres use it too.

“InventoryLab was a no brainer! We wasted so much time our first 6 months shipping through Seller Central and pulling our hair out every time! InventoryLab allowed us to have SMOOTH workflows and saved so much time on shipments.”

Frequently asked questions

InventoryLab brings your whole workflow into one place — from sourcing and listing to shipping and profit tracking. Everything stays connected so your data stays accurate as you work, without switching between apps or exporting between steps.
InventoryLab pulls from Amazon order and settlement reports and Amazon’s APIs — factoring in fees, refunds, returns, and reimbursements. You can also add your own tracked expenses like non-partnered carrier costs or sourcing commissions. The result is a complete margin picture based on what actually happened in your account, not an estimate.
InventoryLab guides you through the full shipment process — adding products, creating inbound plans, assigning box contents, generating labels, and syncing with Amazon — all within one structured workflow. No Seller Central required.
Yes. InventoryLab includes Scoutify and ScoutX, so you can check pricing, fees, demand, and profit while sourcing in-store or online. Products flow directly into your listing and shipment workflow from there.
Yes. The workflow handles bulk listings and shipments, tracks P&L by supplier and category, and gives you the replenishment data you need to manage volume. Prep centres running wholesale client inventory use InventoryLab too.
InventoryLab tracks FBA, merchant-fulfilled, and unlisted inventory in one place. On Pro, you get replenishment insights based on sales velocity, stock levels, returns, and lead times — so you know what to reorder and when.
You get reporting across products, suppliers, and categories, with returns, reimbursements, and Amazon adjustments factored into your profit calculations. Reports can be sliced by SKU, ASIN, supplier, category, or fulfilment channel.
InventoryLab includes built-in P&L for day-to-day operational decisions — what you’re making per unit, per supplier, per category. InventoryLab Accounting is a separate, deeper layer for tax, books, and external accountant workflows. Most sellers start with InventoryLab; Accounting is for when you need a full bookkeeping solution alongside it.
InventoryLab replaces most of the manual tracking typically done in spreadsheets — costs, inventory, shipments, and profit are all connected in one system. Data can still be exported when you need it.
Most tools focus on one part of the process — profit tracking or shipment creation, not both. InventoryLab connects sourcing, listing, shipping, and profit tracking in one workflow, so your data stays consistent across your entire operation.
Most sellers can connect their account and start listing within the same day. The workflow is guided step by step, so you’re following a structured process rather than building one from scratch.
InventoryLab is currently available for US Amazon sellers. If you sell on other marketplaces, sibling tools in Seller 365 – including SmartRepricer and FeedbackWhiz – support global marketplaces.
