Understanding all-in-one business software
One piece of software for a lot, but not for everything.
All-in-one business software brings tasks, customers, products, and numbers into one shared model. Here you see which areas it sensibly covers, what Peak One can do today, and what you still need your own software for.
Here's what it looks like

Quick overview
What all-in-one business software is.
- All-in-one business software
- Software that connects several business areas such as tasks, customer relationships, products, and key figures on a shared data foundation. The core isn't the number of features but that a customer or a product exists only once and every view shows the same state.
- Example
- A customer no longer sits separately in the CRM, in a spreadsheet, and in the task tool. Whoever follows up on a quote sees the same person who has an open task on the project board.
- Common mistakes
- Confusing all-in-one with “replaces every other piece of software”
- Moving all tools at once instead of starting with one area
- Checking required areas like accounting or payroll only after the decision

Payroll, HR, and e-invoicing

Is this right for you?
Put in honest perspective.
Peak Atlas runs this page. That's why it also says what Peak One isn't built for.
Peak One is a good fit if
- The same customers, tasks, and numbers currently live in several tools, each time a little different.
- You want to keep tools like Shopify, HubSpot, or Slack and still see their data in one place.
- You want to start with one area and not switch everything at once.
Something else fits better if
- You're looking for software that also handles accounting, payroll, and e-invoicing. Peak One doesn't do that.
- You need purchasing, inventory postings, or production planning. Then an ERP system is the right category.
- You want your workflows to actively write into many other tools today. That's planned for Peak One but not yet available.
Frequently asked questions
Briefly answered.
Is all-in-one business software the same as an ERP?
No. An ERP maps core processes such as purchasing, warehouse, production, and financial accounting seamlessly. All-in-one business software connects work, customers, and key figures. Peak One is not an ERP.
What does Peak One not replace?
Your accounting, payroll, and HR administration, plus e-invoicing. For accounting and HR, you can connect sevdesk, Lexoffice, and Personio; the work itself stays there.
Do I have to replace my existing tools?
No. You connect what you already use, such as Shopify, HubSpot, Gmail or Slack. Peak maps external data to the core objects instead of creating a second copy.
How much does Peak One cost?
You start free on the Free plan. Paid plans start at €19 (Peak Tools). All plans are on the pricing page.
Where is my data?
The application and database run in Frankfurt am Main. Access rules at the database level ensure each account sees only its own data.
