Sellerboard vs InventoryLab: which FBA accounting tool?
Sellerboard takes cost from a purchase order and InventoryLab takes it from a listing batch, which is the difference that decides which FBA tool suits you.
Last reviewed 5 min readSupplyForge LLC
Sellerboard is better for wholesale buyers who enter cost through purchase orders, and InventoryLab is better for resellers who enter cost while prepping and listing batches. Both compute net profit after Amazon fees.
Cost entry decides the answer more reliably than any feature grid, because it is the part of the tool you touch every week. This page compares Sellerboard and InventoryLab on COGS entry, settlement handling, reimbursement recovery and pricing as of 3 August 2026.
Where each tool takes cost from
Sellerboard takes cost from procurement and InventoryLab takes cost from the prep bench. Sellerboard documents a purchase order object with four statuses — Draft, Ordered, Shipped and Closed — supplier assignment, purchase order splitting, and Excel or PDF export in the supplier's currency carrying allocated logistics costs and total cost per unit. Closing a Sellerboard purchase order prompts a new COGS batch, so cost basis is a byproduct of buying. InventoryLab captures buy cost, supplier and purchase date at the moment of listing, inside its list-and-ship batch workflow, so cost basis is a byproduct of prepping the shipment.
Work one purchase through both. You buy 400 units across 12 SKUs with $180 of inbound freight. In Sellerboard that is one purchase order with 12 lines and one COGS batch at close. In InventoryLab the same units become cost entries as they cross the prep bench into a shipment batch — equally accurate, attached to work you already do. Sellerboard runs that basis as FIFO, which matters once one SKU has arrived at three prices, as FIFO COGS for Amazon sellers explains.
Sellerboard and InventoryLab side by side
Beyond COGS entry, the two products diverge on procurement objects, packaging and supplier records.
| Tool | How COGS enters | Purchase orders | Supplier record | Sold as |
|---|---|---|---|---|
| Sellerboard | CSV bulk upload per SKU, or a COGS batch when a PO closes | Yes — Draft, Ordered, Shipped, Closed; PO splitting; Excel or PDF export | Supplier directory: contact name, address, phone, email, currency, payment terms | Standalone, four published monthly plans |
| InventoryLab | Buy cost, supplier and purchase date, captured during the list-and-ship batch | None | Free-text or favorite field on a batch | Only inside Threecolts Seller 365 Reseller |
Neither product is a CRM. Sellerboard's supplier directory stores a contact name, phone and email per supplier, but Sellerboard has no deal pipeline, no outbound email sequencing and no call logging; InventoryLab has none of those and no supplier entity at all.

How much do Sellerboard and InventoryLab cost
Sellerboard publishes four monthly plans and a matching annual ladder. InventoryLab publishes no standalone price: inventorylab.com permanently redirects to Threecolts, and InventoryLab now ships as one of ten tools inside the Seller 365 Reseller bundle.
| Plan | Monthly | Annual, per month | Notes |
|---|---|---|---|
| Sellerboard Standard | $19 | $15 ($179/yr) | Up to 3,000 orders/mo; 150 review requests/mo |
| Sellerboard Professional | $29 | $23 ($279/yr) | 6,000 review requests/mo |
| Sellerboard Business | $39 | $31 ($369/yr) | 6,000 review requests/mo |
| Sellerboard Enterprise | $79 | $63 | 30,000 review requests/mo |
| Seller 365 Reseller Standard | $69 | $65 | 1 user, 10 tools including InventoryLab |
| Seller 365 Reseller Teams | $129 | $119 | Up to 10 users |
| Seller 365 Reseller Pro | $199 | $183 | Top Reseller tier |
Two caveats belong with the Threecolts column. Threecolts split Seller 365 into Reseller and Brands bundles on 29 July 2026, and InventoryLab is absent from Brands, so Brands prices are not a route to InventoryLab. Multichannel selling is excluded from the Reseller price — the UniCon add-on costs $49, $89 or $449 a month.
Settlement handling and what neither tool does
Neither Sellerboard nor InventoryLab is a settlement-to-general-ledger connector, and treating either as bookkeeping is the most common mistake sellers make. Sellerboard models Amazon fees, refunds and reimbursements in a live dashboard with FIFO COGS and amortized fees. InventoryLab reports net profit and ROI after Amazon fees and tracks expenses, mileage and overhead. Neither posts accrual-correct journal entries into accounting software.
Posting journal entries is a settlement connector's job. A2X turns each Amazon settlement into a summarized journal entry and posts it to QuickBooks Online, Xero, NetSuite or Sage, and launched A2X Clarity in December 2025. Link My Books does the same job with stronger VAT handling, and raised base plan prices effective 1 July 2026. Running one dashboard and one connector is normal, and the gap between their numbers is the main reason Amazon profit tools disagree with each other.
Reimbursement recovery is priced very differently
Reimbursement recovery is where the real cost difference sits, and it is a commission, not a subscription. Threecolts adds a Reimbursements tool to every Seller 365 tier on a pay-on-recovery basis: 15% of recovered funds, dropping to 5% only on the top plan, checked 3 August 2026. Recover $10,000 in a year and the 15% rate costs $1,500 — more than a year of the Standard Reseller bundle at $65 a month billed annually.
Sellerboard's published pricing carries no success fee on recovered funds, and Sellerboard models refunds and reimbursements inside the profit dashboard. Neither approach is wrong: a commission costs nothing when it recovers nothing; a flat dashboard costs the same whether you chase claims or not. The deciding variable is how much Amazon owes you — estimate that first, starting with what you can claim in Amazon FBA reimbursements.
Which one to choose
Choose Sellerboard if you buy on purchase orders from distributors and want cost to flow from procurement into COGS without a second data entry, at the lower published price. Sellerboard also covers Walmart and Shopify alongside Amazon.
Choose InventoryLab if your week involves receiving, prepping and listing units. InventoryLab's batch listing, box-content tracking and label printing are best-in-class for that workflow, and its target-ROI pricing back-solves a list price from the ROI you want. InventoryLab also surfaces replenishment timing from sales velocity, stock levels, returns and lead times, so it is not purely rear-facing. Weigh one packaging fact: InventoryLab cannot be bought standalone any more.

Frequently asked questions
Does Sellerboard have purchase orders
Yes. Sellerboard's help center documents a purchase order object with Draft, Ordered, Shipped and Closed statuses, supplier assignment, PO splitting and Excel or PDF export. Closing one prompts a new COGS batch.
Can I still buy InventoryLab on its own
No. As of 3 August 2026 inventorylab.com permanently redirects to Threecolts, and InventoryLab sells only inside the Seller 365 Reseller bundle — not the Brands bundle Threecolts introduced on 29 July 2026.
Do I need accounting software as well as Sellerboard or InventoryLab
Yes, if you keep books on an accrual basis. Neither tool posts journal entries to QuickBooks Online or Xero; a settlement connector such as A2X or Link My Books handles that layer.
