Automate your store operations.
Warehouse, Shopify and Klaviyo in sync – no spreadsheets.

We build and run the automation between your warehouse management, Shopify and marketing stack: order and stock sync, catalogue updates, loyalty logic, Klaviyo events, reports and monitoring. Not a no-code chain that breaks on the first edge case, but code you own – on the operations platform we use every day to run Klean Kanteen Germany and MADSea.

Is this you?

The store grew. The manual work grew with it.

Merchants who call us are not short of tools. They are short of connections between them – and somebody on the team is bridging the gap by hand every single day.

Stock is wrong somewhere

The warehouse says 12, Shopify says 3, the marketplace sold the last unit twice. Every oversell costs a refund, a support ticket and a customer.

Orders are copied by hand

Someone exports orders from Shopify and imports them into the warehouse system – or re-types them. It works until the day that person is on holiday.

Marketing does not know what the shop knows

Back in stock, loyalty points, first purchase, return – events that should trigger an email trigger a to-do instead.

Nobody notices when something breaks

The sync stopped on Friday night. You found out on Monday, from an angry customer. Automation without monitoring is just a faster way to make mistakes.

What we build

The connections your tools were missing.

We build the integration layer between warehouse management, Shopify and marketing – as code on our operations platform, extended for your setup. Six areas we automate most often:

Order and stock sync ERP ↔ Shopify

Orders flow from Shopify and marketplaces into plentymarkets or your warehouse system; stock, prices and shipping status flow back. One unified order table across all your shops, with history.

Product catalogue and product setup

Hourly catalogue sync including sales figures per SKU, plus product-setup workflows: checklists whose steps tick themselves off from plenty or Shopify data.

Klaviyo and marketing events

Loyalty points and tier changes, back-in-stock, review requests, daily list hygiene – pushed to Klaviyo as events and profile properties, so your flows fire on real shop data.

Loyalty programme and member area

Points, tiers and rewards computed from orders and returns, a member area inside the Shopify theme, events to Klaviyo – the way we run the MADSea Crew programme.

Customer 360 and reporting

One profile per customer across all shops: orders, returns, loyalty status, consent. Scheduled reports and dashboards instead of Monday-morning Excel.

Monitoring, alerts and scheduled jobs

Scheduled reconciliations, alerts on failed jobs, thresholds for stock, sync lag and error rates. You hear it from us – not from a customer.

How it works

From audit to a running system in five steps.

Every automation starts with a written picture of what happens today – who touches which data, where and how often. Then we build in short, visible increments.

  1. Step 01Week 1

    Process audit

    We map your order, stock, catalogue and marketing processes end to end, count the manual steps and list every system and API involved. You get a written plan with priorities and a fixed quote.

  2. Step 02Week 1–2

    Technical concept

    Data model, direction of each sync, conflict rules (who wins when stock differs), error handling and alerting – agreed before the first line of code.

  3. Step 03From week 2

    Build and test

    Integrations are built in a staging setup against your real systems, with test orders and reconciliations against the counts in your source system. Weekly demo.

  4. Step 04Step by step

    Go-live, one workflow at a time

    Each automation first runs in parallel to the manual process, with reconciliation reports. Once the numbers match for a few days, the manual step is retired.

  5. Step 05Ongoing

    Operate and extend

    Monitoring with alerts, scheduled reconciliations, documentation and a monthly look at what to automate next. Or a full hand-over to your team.

Pricing and working together

Fixed price for the build. Monitoring for the run.

Automation only pays off if it keeps running. That is why we quote the build at a fixed price and offer the operation as a retainer – with code and all accounts belonging to you from day one.

Getting started

Automation audit + implementation

A one-week audit of your processes, then the implementation of the agreed workflows at a fixed price.

  • Written plan and quote after the audit
  • Prioritised: biggest manual effort first
  • Go-live per workflow, with reconciliation
Connected systems

Integration project

ERP or warehouse system ↔ Shopify ↔ marketing stack as one integration: orders, stock, catalogue, customers, events – including conflict rules and monitoring.

  • plentymarkets, JTL and other systems with a REST API
  • Technical concept before the build
  • Staged rollout, old process runs in parallel
Keep it running

Operations retainer

We run the automations: monitoring, alerts, adjustments when an API changes, a monthly look at the next step – the way we have worked with Klean Kanteen Germany since 2017.

  • Monitoring with alerts included
  • Fixed monthly hours, flexible use
  • Cancel monthly
What we commit to
  • Code, repositories and accounts belong to you
  • Monitoring with alerts for every automation we ship
  • Documentation your team can actually read
  • Reconciliation against the source system before a manual step is retired
  • No lock-in: standard APIs, no proprietary middleware
  • Fixed price for a fixed scope

FAQ

Questions merchants ask before they automate.

What can actually be automated in an online store?
Anything that follows a rule and touches data in two systems: orders into the warehouse system, stock back to Shopify, price and catalogue updates, shipping status, returns, invoices, loyalty points, back-in-stock and review emails, list hygiene, reports. If someone on your team does it the same way twice a week, it is a candidate. The audit lists them and sorts by effort saved.
We use plentymarkets, JTL or another warehouse system. Does that work?
plentymarkets we run in production ourselves – including order and stock sync and the quirks of its REST API. JTL and other systems with a REST or SOAP API, CSV exports or database access we connect the same way. If a system has no interface at all, we tell you so in the audit.
Why not just use Shopify Flow or Zapier?
Use them where they fit – Shopify Flow is great for tagging, simple notifications and conditions inside Shopify. They stop where it gets interesting: two-way stock sync with conflict rules, large catalogues, retries when an API is down, history, reporting. We build that as code with tests and monitoring – and keep using Flow for the simple cases.
What happens when something goes wrong?
Every job logs what it did and raises an alert when it fails, lags behind or produces numbers that do not match the source system. Failed runs retry automatically; whatever still fails lands in a queue for review – not in a silent hole. You get the alerts too, if you want them.
Where does the data run? Is it GDPR-compliant?
Our platform runs on AWS and Vercel; for client projects we provision databases and functions in EU regions. Credentials are stored encrypted, data is strictly separated per company, and access requires two-factor authentication. We sign a data processing agreement and document which data flows where.
How long does it take?
The audit takes about a week. A first workflow – say, stock sync from the warehouse to Shopify – is typically live within a few weeks; a full ERP ↔ Shopify ↔ Klaviyo integration is a project of a few months, rolled out workflow by workflow. The plan after the audit gives you dates.
What does it cost?
The audit has a fixed fee, the implementation a written fixed price per scope after the audit, the operation a monthly retainer you can cancel monthly. No hourly billing – and no price list on this page, because no two setups are alike. We would rather send you a real number after the audit call.
What if we want to take it in-house later?
Then you take it. The code lives in a repository you own, API credentials and accounts are in your name, every automation has documentation and a runbook. We hand over with a walkthrough for your developers and stay available as long as you want.
