Sellerboard tells you what happened at the SKU level. Tideline handles what happens next.
Sellerboard is best-in-class at per-SKU profit and loss reporting on Amazon. It stops at the dashboard — the ad pause, the FBA reorder draft, and the overnight buyer-message reply still need a human reading the email at 8 a.m. Tideline runs that loop against the same numbers.
Best-in-class P&L. Reports what happened — does not run what happens next.
Sellerboard
Strength: Granular profit/loss per SKU
The gap: Reports what happened — no overnight automation, no action queued
Three surfaces Sellerboard never touches.
Same Amazon stack — Sponsored Products, FBA velocity, buyer messages — the overnight loop that runs on top of it.
- Sellerboard shows the ACOS bleed. Tideline pauses the campaign.Sellerboard's P&L dashboards tell you the per-SKU profit drift after the spend has already happened. Tideline reads Sponsored Products bids overnight, flags drift past your TACoS guardrail, and queues the pause before your planner opens Slack.
- Sellerboard reads sell-through. Tideline drafts the restock PO.Per-SKU velocity is exactly what Sellerboard was built for. Tideline takes that same velocity, folds in lead times, and parks a reorder draft in your Rules queue — you approve the order, you do not type the SKU list.
- Sellerboard does not touch buyer messages. Tideline drafts in your voice.Amazon's 24-hour SLA on buyer messages is unforgiving, and Sellerboard stops at the analytics layer. Tideline trains on three of your own past replies and drafts a response for every new buyer message — pre-approved tone, ready before the clock runs out.

When Sellerboard is still the right choice.
If P&L reporting is the only thing you need, Sellerboard remains best-in-class on that surface alone. The overlap shifts once overnight action matters.
Per-SKU P&L deep dive. If you need single-SKU margin breakdowns across fees, storage, returns, and ads, Sellerboard reports it with a level of granularity Tideline does not replicate. Use Sellerboard for the report; layer Tideline on top for the action.
Read-only reporting workflow. If your operating model is "produce the weekly P&L deck and never auto-execute anything," dashboards alone cover it. Tideline is built for teams that want the agent to queue the action — approval optional, autonomy tunable per use case.
