New: custom tool development for marketplace teams

Your workflow.
Your tool. Your data.

You do not need a €3,000 suite of which your team uses 10 %. Out of 8 years of marketplace practice we build exactly the tool your workflow is missing — from a rank tracker to a bid engine that follows your rules. EU-hosted. It is yours.

# This is how simply your tool starts:
tool:        rank-tracker
marketplaces: [amazon.co.uk, amazon.de]
keywords:    240 from your list
frequency:    daily at 06:00
alerts:      Slack, when rank drops > 5
hosting:     EU (Germany)
owned by:      you

You pay for 25 features.
You need one — but exactly right.

In-house teams at strong brands know exactly what they need. The big tool suites still deliver the whole bundle — on their terms, inside their black box, on their servers.

Renting a tool suite

  • €500–3,000 per month — permanently, for the whole bundle
  • The one workflow you need works “something like that”
  • Black-box algorithms decide your bids
  • Your account data usually sits on US servers
  • Cancel and it is all gone — data, history, logic

Having your own tool built

  • A one-off setup plus a lean monthly running fee
  • Exactly your workflow, your rules, your thresholds
  • Every decision traceable, audit log included
  • Hosting in Germany, GDPR-compliant, data processing agreement included
  • The logic and the data are yours — permanently

Proven building blocks, wired up for you

We build every tool on a proven technical base drawn from 8 years of marketplace practice — the bespoke part sits where it matters to you: in your logic. That is why we deliver in weeks, not months.

Your special case

The workflow no tool in the world covers? That is exactly what we are here for. Tell us what costs you hours every week.

Fixed price after specification

All prices are guide figures for getting started — the fixed price is set after the workflow call. The monthly running fee covers hosting in Germany, API upkeep (Amazon, Otto, Kaufland, bol & co. change their interfaces constantly) and smaller adjustments.

From your workflow to a running tool

No flying blind — four clear steps, starting with the first call.

STEP 1

Workflow call

30–45 minutes: what do you do by hand today, and what exactly should the tool do? Free and with no obligation.

STEP 2

Specification & fixed price

You get a clear specification with a fixed price for setup and operation. No open-ended estimate.

STEP 3

Build in 2–4 weeks

We implement your specification. You authorise the API access, we deliver on the agreed acceptance date.

STEP 4

Operation & further development

We keep the tool running — monitoring, API updates, adjustments. You simply work with it.

Before you ask

What teams ask us most often before their first tool project.

Why not just build it ourselves — with AI that is quick, isn't it?
Writing the script is the smallest part. The real work is keeping a tool running reliably over years — the marketplaces change their interfaces and requirements constantly. That is exactly what we take on: your team uses the tool instead of maintaining it.
Who owns the tool in the end?
Yours. The logic developed for you and your data are yours contractually. We run the underlying technical infrastructure — which keeps your tool cheap to operate and automatically up to date with the marketplace interfaces.
How secure is our account data?
Hosting exclusively in Germany, data processing agreement included. API access runs through the marketplaces' official authorisation procedures — you can see and revoke every access yourself. Credentials are stored encrypted, never in plain text.
What does ongoing operation cost?
Depending on the module and the data volume, a monthly fee from around €150 — covering hosting, monitoring, API upkeep and smaller adjustments. The specification gives you the exact figure before you decide.
Who is this worth it for?
For brands with their own marketplace team from around €2m in marketplace revenue — wherever a specialist currently wrestles with suite licences or maintains Excel workarounds instead of working with a tool that fits exactly.

Tell us what costs you hours every week.

In the workflow call we work out in 30–45 minutes whether and how your process can be built as a tool — and afterwards you get a specification with a fixed price. No obligation.
