Shop, app, marketing or AI – what first? The Digital Stack Builder
Pick your goals, answer four short questions and get your digital plan in three phases – including the legal duties that probably apply to you.
- Free
- No sign-up
- Fixed calculation rules, no AI
Question 1 / 5
What do you want to achieve?
Pick up to six goals in order of importance. The number shows the priority.
A building block is a self-contained project, such as “Replace your shop platform”, “Connect your systems” or “Process documents automatically”. Each block lands in a phase – now, the next three months or later – with a reason and a link to the matching service. No sign-up needed for the plan; the rough budget comes by email.
Three phases, clear building blocks
Every building block is a self-contained project and lands in one phase – with the reason and a link to the service.
Now
Start whenever you like.
Next 3 months
Follows the first steps.
Later
Worth it once the basics are in place.
Example: a wholesaler's plan
This is what a result looks like. The answers run through the same rules as your own.
Build your own planA wholesaler with 80 employees sells to business customers on Shopware 5; stock and invoices run in the ERP. Top goal: less manual work between shop, ERP and inbox.
- Goals
- Automate processes
- Business model
- Trade or manufacturing for businesses
- Size
- 50–249 employees
- Online shop
- Shopware 5
- Systems
- ERP
- Scope
- One project
Now
Start whenever you like.
- Shop
Replace your shop platform
Why: Shopware 5 has had no official security updates since the end of July 2024, so moving to Shopware 6 comes before everything else.
- AI
AI workflows
Why: Fastest lever for “Automate processes” – you can start without a big project.
Next 3 months
Follows the first steps.
- Software
Connect your systems
Why: Builds on “Replace your shop platform” and only pays off after it.
- AI
Process documents automatically
Why: Complements the first blocks once they show results.
Later
Worth it once the basics are in place.
- Software
Custom software
Why: Fits your goals but has less leverage than the blocks before it – tackle it later.
- Marketing
CRM and marketing automation
Why: Fits your goals but has less leverage than the blocks before it – tackle it later.
