VARTANIAN CAPITALSeller Toolkit

For Amazon sellers

Know what you actually made — after every Amazon fee.

Seller Toolkit connects to your Amazon account, imports your real sales and fees, and applies your cost of goods automatically. Plus a supplier CRM, shipping calculators, and product research — in one place instead of six subscriptions and a spreadsheet.

  • No sales to log by hand
  • Your data stays yours
  • Disconnect anytime

Everything in one workspace

Each tool feeds the next — a supplier you vet becomes a supplier you track, whose products become the costs behind your profit numbers.

Product analyzer

Paste any ASIN and see Amazon's real referral and FBA fees, sales rank, buy box, competition, package size — and whether your account is actually approved to sell it. Then your profit, margin, and ROI at any cost.

Bulk list scanner

Paste a whole supplier price list and find the winners in one pass. Real fees and profit for every ASIN, sorted by ROI, with gating flagged before you buy stock. Export to CSV.

Profit & COGS tracking

Connect your Amazon account and your sales and real fees import automatically. Set each product's cost once and see true net profit, margin, and ROI per product — no logging sales by hand.

Supplier CRM

A pipeline for sourcing: track suppliers from first contact through quotes, samples, negotiation, and active orders. Keep contacts, products, quotes, and notes in one record instead of scattered inboxes.

Shipping calculators

Estimate the cost of sending units into Amazon via a partnered carrier — billable weight, boxes, cost per unit — plus a separate calculator for sea and air freight from your supplier.

Product & supplier research

Pull product details by ASIN, scrape a supplier's catalogue into a structured product list, and save promising finds straight into your CRM.

Supplier vetting

Background-check a supplier before you wire money — company details, red flags, and what turns up publicly about who you're dealing with.

Review analysis

Read what buyers actually complain about in a product's reviews, so you know the defect to fix before you source a competing version.

Follow-up reminders

Suppliers go quiet. Set a follow-up on any conversation and see everything due on your dashboard.

AI assistant

Ask sourcing and product questions in plain English. AI-powered features are an optional add-on — contact us to enable them on your account.

Your account data is yours

You authorize on Amazon's site

We never ask for or store your Amazon password. You approve access on Amazon directly, and you can revoke it whenever you want.

Encrypted access tokens

The token that lets us read your account is encrypted before it is stored.

Isolated by customer

Every record is walled off at the database level, so no other customer can reach your data.

We don't sell your data

Your sales, suppliers, and costs are never shared, resold, or pooled with anyone else's.
