SellerMatrix vs Sellerboard — Honest Comparison

What both do well

If you already run Sellerboard, keep using it while you weigh this up. It is the affordable profit-analytics default for a reason, and a lot of what it does is exactly what a profit tracker should do.

Sellerboard is the affordable defaultIt has been the go-to low-cost profit tool for years. If you want solid profit analytics without a big monthly bill, it earns its place — plenty of sellers run their whole business on it.

Solid profit and lossIts P&L pulls your Amazon fees, refunds, costs and payouts into one view. That is the core job of a profit tracker, and Sellerboard does it properly.

Both read from sourceSellerboard and SellerMatrix both connect to your Seller Central and advertising data through Amazon's official API, so the numbers come from Amazon rather than hand-entry.

Where Sellerboard stops

None of this makes Sellerboard a bad tool. These are just the gaps we kept hearing about from sellers — and the reasons we built something narrower.

It gives you the numbers, not the next moveSellerboard shows you a rich dashboard and then leaves you to work out what to do with it. On a busy week, "here are all your metrics" can still leave you unsure where to start.

It isn't VAT-first for UK sellersVAT shapes a UK seller's real profit. A tool built US-first can leave you doing VAT in your head, or in a spreadsheet, before you can trust the bottom line.

Trusting the profit number itselfThe concern sellers raise most often is simply whether to trust the profit figure — that every fee, refund and cost is captured. If you don't trust the number, you can't act on it.

What SellerMatrix adds

SellerMatrix is deliberately narrower. It is built to answer four questions: am I profitable, how do I make more, what are my top jobs this week, and can you make Amazon make sense. Here is what that looks like in practice.

One ranked action every Monday, 7amA plain-English email with the single most profitable thing to do this week, ranked by its £ impact — not a wall of charts you have to interpret yourself.

TACOS, not just ACOSWe lead with total advertising cost of sales (TACOS), so you see what ads really cost the whole business — not only the spend measured against ad-attributed sales.

Is SellerMatrix a replacement for Sellerboard?

If you want a low-cost profit dashboard, Sellerboard already does that well.

Does SellerMatrix handle UK VAT?

Yes. The profit and loss is calculated VAT-first for UK sellers and works across both UK and US Amazon, so the profit figure you see is the profit you actually keep rather than a pre-VAT number you have to adjust yourself.
