Vendlen and Sellerboard.
Not the same job. One tells you what a product earned after Amazon took its cut. The other tells you that and then acts on the advertising behind it. Most people weighing these two already run a profit dashboard, so the question is what a second subscription is for.

What Vendlen carries

- 5Rule familiesBidding, dayparting, negation and unnegate, negative word, and keyword import. Blacklist and Whitelist sit at ASIN level beside them.

Side by side
A report, and a decision.
Both put every Amazon charge where you can see it. The difference is what happens next: one finishes at the figure, the other treats the figure as the context for an advertising decision it can write down and then carry out inside limits you set.
What the product is for
Vendlen
Deciding what to do about advertising, with the profit behind it in the same place. Profit Intelligence is the business context under an advertising decision, not a separate report you open.
Sellerboard
Knowing what a product earned. A real-time profit dashboard with inventory management, listing change alerts, PPC optimization, refunds for lost inventory and an LTV dashboard.
What the bill scales with
Vendlen
Monthly Amazon ad spend on the Ads ladder, or monthly Amazon revenue on Analytics Only, which starts at $59. No cap on how many products you automate, and no share of spend.
Sellerboard
Orders a month. Their published tiers run from 3,000 orders to 50,000, from $15 a month.
What happens after the number
Vendlen
AI Analyst reads the advertising record and the relationships between your products, then writes a Decision Brief — the action, the reason, the evidence rows, the period and the scope. It does not read Inventory, so no proposal is argued from how much stock you hold. Automation then carries the decision out inside limits you set; Campaign Builder writes the structure, and Listing prepares copy for review.
Sellerboard
The figure in real time, with PPC optimization alongside it. What to change in the advertising is a decision you take from the dashboard.
How a cost is broken down
Vendlen
Every Amazon charge on its own line — freight, duty, storage, fulfilment, transfers, clawbacks and reimbursements — with cost of goods held as a weighted average that updates from each inbound shipment.
Sellerboard
A real-time profit dashboard covering the same ground, with refunds for lost inventory tracked alongside it.

If you already run one
What the second subscription would be for.
Three things Vendlen does with the profit figure once it has it. Each is a mechanism, with the documentation that specifies it, so you can settle it against whatever you run today.
A decision written down, with its evidence
AI Analyst reads the account and writes a Decision Brief: the action, the reason, the rows the reason rests on, the period they were read at, and the scope it applies to. You read it and decide whether to apply it.
The decision repeated, inside limits you set
Four trigger modes carrying published arithmetic, including one that measures money lost against an economic threshold rather than an ACOS ratio — so a target losing $8 and one losing $800 are not the same event. Every run previews before it acts and records what it did.
Structure and copy, not just measurement
Campaign Builder expands one template over a Product Group into fourteen campaign types, named consistently and created paused. Listing prepares Amazon copy for review, and you decide whether it is sent.
Buy theirs, not ours
Three cases where Sellerboard is the better buy.
You want a profit dashboard and nothing else
Their published tiers start at $15 a month. If advertising automation is not what you are shopping for, a second tool that carries it is a cost with no job to do.
You sell beyond Amazon, or beyond one marketplace
Their pricing page lists Shopify and Walmart alongside Amazon, and their tiers include additional seller accounts. Vendlen covers Amazon United States.
Order volume is your cost driver, not ad spend
Their bill follows orders a month; ours follows ad spend, or revenue on Analytics Only. A high-volume, low-spend account sits on the cheap end of their axis and further up ours. Run both numbers on your own account — it is the only way to settle it.
The profit figure, and what to do about it.
Every Amazon fee on its own line, and an advertising decision written against it with the evidence attached. Connect the account you already run.
