Sellerboard vs InventoryLab: Which Amazon Tool Do You Need?

Sellerboard vs InventoryLab is one of the most common questions Amazon sellers ask, and the honest answer is that they are built for different jobs. I use both tools every week for a US Amazon seller, so in this guide I will show you what each one really does, how much they cost, and which one (or both) your business needs.

Quick Answer: Sellerboard or InventoryLab?

Choose Sellerboard if your main question is “Am I actually making money?” It is the better tool for daily profit tracking, PPC costs, refunds and restock planning, and it is cheaper.

Choose InventoryLab if you buy products to resell (online arbitrage, retail arbitrage or wholesale) and send many FBA shipments. Its strength is listing, batching and labelling stock, while saving your buy cost for every unit.

If you do both, sourcing and shipping a lot and want detailed profit analytics, using both tools together is common and works well.

What Is Sellerboard?

Sellerboard is a profit analytics tool for Amazon sellers. It connects to Seller Central and calculates your real profit after Amazon fees, refunds, advertising, shipping and cost of goods, by day, by product and by marketplace.

The main dashboard shows tiles for today, yesterday, month to date, a forecast for this month and last month. Each tile shows sales, orders and units, refunds, ad cost, estimated payout and net profit. Sellerboard also includes:

• A P&L view and product-level profit tables
• PPC analytics and optimisation
• Inventory management and restock suggestions
• Automated review requests (autoresponder)
• Listing change alerts
• Refunds for lost and damaged FBA inventory

It works with all Amazon marketplaces, and Sellerboard also lists support for Walmart and Shopify.

What Is InventoryLab?

InventoryLab is built for resellers who source products and send them to Amazon. You add products to a batch with their buy cost, list price and quantity, then create the FBA shipment, print labels and send the stock, all without working inside Seller Central.

Because every unit is saved with its buy cost, InventoryLab can produce accurate profit and loss reports by product, supplier or channel. The standalone plan also includes:

• FBA and FBM listing with a guided shipment workflow
• Scoutify mobile sourcing app with profit insights
• InventoryLab Accounting for bookkeeping and tax
• Local stock tracking and buy lists

InventoryLab is now part of Threecolts, and it currently supports US Amazon sellers only.

Sellerboard vs InventoryLab: Side-by-Side Comparison

Prices checked in October 2026 on the official websites. Always confirm the current price before you subscribe.

Pricing Compared

Sellerboard has four plans billed monthly: Standard $19, Professional $29, Business $39 and Enterprise $79 per month. Paying yearly lowers the cost (Standard works out at about $15 per month). Higher plans add more orders, users and features. There is a one-month free trial and no credit card is needed.

InventoryLab costs $69 per month, or about $58 per month on a yearly plan, with a 30-day free trial and unlimited users. Restocking Insights is an extra $25 per month. InventoryLab is also included in the Threecolts Seller 365 bundle (from $69 per month), which adds tools such as a repricer and reimbursement service.

For a small seller watching costs, Sellerboard is the cheaper start. For an active reseller sending shipments every week, InventoryLab usually pays for itself through time saved on listing and labelling.

How I Use Both Tools for a Client

For a US sports retailer selling on Amazon, eBay and Whatnot, I used both tools side by side, together with Valence for audits:

1. InventoryLab for incoming stock. New purchases were added to FBA batches with their buy cost, then shipped to Amazon warehouses with the right labels.
2. Sellerboard for daily profit. Each morning I checked yesterday’s sales, refunds and net profit, and flagged products with falling margins or high refunds to the owner.
3. Keeping costs in sync. Cost of goods and shipping costs had to be updated in Sellerboard too, otherwise profit numbers look better than reality.
4. Valence for reimbursements. Lost and damaged inventory was followed up as cases, with more than $10,000 claimed in 12 months.

You can see the screenshots and results in my multichannel case study and on my tools page.

Which One Should You Choose?

• You sell your own brand (private label): start with Sellerboard. You rarely need batch listing, but you need profit, PPC and restock data.
• You do online or retail arbitrage: start with InventoryLab. Listing and shipping speed matter most, and buy costs are captured automatically.
• You sell wholesale with many shipments: InventoryLab for shipments, plus Sellerboard if you want deeper daily analytics.
• You sell outside the US Amazon store: Sellerboard, because InventoryLab currently supports Amazon US only.
• You are short on time for either: a trained virtual assistant can run both tools for you, keep costs updated and send you a simple weekly report.

Setup Tips That Save Hours

• Enter cost of goods from day one. Both tools are only as accurate as your buy costs.
• Add shipping and prep costs. Inbound shipping to Amazon is easy to forget and quietly eats margin.
• Use the free trials together. Run both for a month and compare which reports you actually open.
• Give your VA a separate user. Both tools support extra users, so you never need to share your own login.
• Check reimbursements monthly. Lost and damaged FBA units add up quickly on busy accounts.
