One cockpit for your entire e-commerce

Don't optimize for ACoS.
Optimize for your contribution margin.

The real problem

The best PPC agency in the world won't help you if you can't see what's tied up in your inventory, where you can scale and where your capital is stuck.

// Optimizing ads without inventory and cost visibility = flying blind at full throttle.

The difference

Others optimize for metrics. You optimize for profit.

ACoS and TACoS tell you what advertising costs — not what's left at the end. StockProfit nets cost of goods, fees, returns, shipping and ad spend against each other until only one thing remains: your maximum contribution margin per SKU.

Standard tool Steering by ACoS / TACoS

Metric down — profit too.

You cut bids until the ACoS looks "nice". Revenue collapses, fixed costs keep running, inventory ages. The number is right, the cash register isn't.

ACoS18.0 %
Revenue–24 %

StockProfit Steering by contribution margin

Every click pays into your CM.

Bids follow the real contribution margin per SKU. Products with headroom get pushed, capital-eaters throttled — automatically, based on your real costs.

See, decide, act — on a single surface.

Profit dashboard

Profit in real time — across every channel.

Amazon, Shopify and Temu at a glance. From revenue through every cost block down to contribution margin per brand, channel and SKU. No more Excel nights at month-end.

  • CM I & CM II live per SKU instead of once a month
  • All fees, returns & shipping already netted out
  • FBA reimbursements detected automatically (MoneyBack)

PPC optimizer

Your campaign management, steered by profit.

Bids are set not by gut feeling but by the contribution margin of each SKU. Four regimes from "push" to "clamp" — with a circuit breaker that instantly catches escalating campaigns.

  • Bid recommendations per target on a CM basis
  • TACoS governor per product family
  • Parked & burned targets flagged automatically

Inventory management

Never out of stock. Never dead capital.

A missed reorder point costs you twice: the revenue during the stockout — and the hard-won ranking afterwards. StockProfit monitors every location in real time, calculates demand from your real sales velocity and tells you to the day when to reorder and ship in.

Live stock across all warehouses

Amazon FBA (DE/EU), your prep & fulfillment warehouse and JTL in one place. Coverage in days with a traffic-light signal — you see instantly where it's getting tight.

Forecast with seasonality

Forecast based on your real history — seasonal peaks factored in and stockout phases cleaned up, so past shortages don't distort your planning.

Reorder & FBA in seconds

Optimal order and ship-in quantities calculated automatically, adjustable anytime. Delivery plans and shipping labels go straight to your logistics provider — storage location included.

Coverage traffic light

At a glance: scale up or restock?

Every SKU shows its coverage in days and a clear recommended action. And because StockProfit knows the contribution margin, it distinguishes what you restock — from what you're better off selling down instead of sinking fresh capital into.

  • Green / yellow / red instead of a wall of numbers
  • Reorder quantity recommended automatically
  • Capital-binders without CM are steered out, not reordered

Sales forecast

Plan the season before it arrives.

StockProfit mirrors your real sales of the last 12 months into the future — back-to-school, Christmas, tournament peaks included. So you order in time, but never so much that capital falls asleep on the shelf.

  • Seasonality detected automatically
  • Stockout-cleaned history — no distorted forecasts
  • Cash-flow & capital-commitment planning for your accountant

  • Storage-location tag right on the label

Deal calendar · 30-day low-price protection

Plan promotions without wrecking your next deal.

Amazon only accepts a deal if your price hasn't been lower in the last 30 days. So a spontaneous discount can ruin your Prime Day deal or your strike-through price. The deal calendar knows every planned promotion, watches the lock-out window and warns you before you break it.

  • Automatic 30-day low-price lock per SKU
  • Warning when a promotion violates a lock-out window
  • Deal price checked against CM — is the discount even worth it?

2018
By sellers, for sellers

We don't build a tool on paper. We sell ourselves.

StockProfit grew out of our own daily e-commerce grind — Amazon, Shopify, Temu, FBA, JTL. In the e-commerce world since 2018, we know exactly where it hurts: capital in the wrong inventory, PPC without cost visibility, three tools for one question.

Every feature exists because we needed it ourselves. No feature zoo — only what makes decisions faster and more profitable.

// real practice, not a feature list

AI analysis with Claude

Always fully focused on what matters right now.

The built-in AI reads your live data across every module and tells you in plain language what matters today: which SKU to ship in, which campaign is running off the rails, where capital is tied up. You ask in plain English — StockProfit answers with your numbers, not platitudes.

Example questions Why did my contribution margin drop this week? What should I ship in before back-to-school? Which campaigns are burning money right now?
Based on Claude, the AI model by Anthropic
You
What should I focus on today?
StockProfit AI
Three things: Kinny Cup has only 6 days of coverage left at a positive CM → ship in today. Set "WM26" ties up €18,400 with no demand → sell it down instead of restocking. And campaign Bia · Auto is at −€0.20 CM/order → I've flagged it to clamp.

Frequently asked

Answered briefly.

Everything else we clear up in the onboarding — openly, on your real numbers.

Which channels and systems can I connect?+
Currently: Amazon (SP-API), JTL-Wawi, Shopify and Temu — plus Google Ads and Meta Ads for ad spend. We keep adding channels; just ask about your setup in the onboarding.
Where is my data stored and who can access it?+
Your data flows encrypted through the official platform APIs and sits on servers in Germany. We share nothing with third parties and use your data only for your cockpit. You can revoke the access grants (API tokens) yourself at any time. Details: privacy policy.
Does StockProfit change my bids automatically?+
For every target StockProfit computes a clear recommendation based on contribution margin — from “push” to “clamp”. A circuit breaker catches escalating campaigns immediately. How much of it runs automatically, and where you keep the final say, you set yourself.
What does StockProfit cost?+
StockProfit bundles four subscriptions into one — all modules included, no setup fee, cancel monthly. For comparison: the usual tool stack of profit analytics, inventory management and a PPC agency runs 600–2,300 € per month. We tell you your exact price in the onboarding — tailored to your setup.
How long does setup take?+
The onboarding takes about 45 minutes over video call. We connect your channels together, enter your costs, and you start right away with real numbers. Historical data flows in automatically afterwards.
I already use Sellerboard or Ventory One — how do I switch?+
No problem: you can run StockProfit in parallel until you are confident. We take over your product costs in the onboarding so the contribution margin is right from day one.
Can I cancel monthly?+
Yes, StockProfit can be cancelled monthly. No minimum term, no setup fee — if it does not help you, you leave again.
Do I need JTL to use StockProfit?+
No. JTL-Wawi is one of several connections. Pure Amazon or Amazon-plus-Shopify setups work too — the cockpit always shows exactly the channels you connect.
Ready for full visibility?

One cockpit. Every channel.
Full focus on your profit.
