What This Is About
A side business in Germany does not need a complete tool ecosystem right away. At the start, three things matter: keeping your money clearly separated, capturing receipts properly, and not losing track of customer contacts.
Everything else depends on your business model. An Etsy shop needs different tools than a UGC creator, an agency, a local service provider, or a digital consultant.
The Simple Starter Stack
Business account: so that income and expenses do not get mixed up with your personal account.
Accounting or invoicing tool: as soon as you write invoices regularly, need to collect receipts, or VAT (Umsatzsteuer) topics come up.
Website or simple landing page: if customers are expected to check you out via Google, social media, or referrals.
CRM or contact list: only relevant once you are managing several leads at the same time or want to handle follow-ups systematically.
Newsletter tool: useful if you want to reach the same target audience repeatedly. Not useful if you do not yet have a list, a content rhythm, or a consent process in place.
Common Mistakes
Too many subscriptions too soon: 8 tools at €20 each sounds small, but that is nearly €2,000 a year. For a side business, that can eat up your entire profit.
Tools without a process: A CRM only helps if you are actually nurturing leads. A newsletter tool only helps if you send regularly. A website only helps if it builds trust or gets found.
Planning around free plans as a permanent setup: Some free plans are great for testing, but commercial use, usage limits, data protection, data export, branding, or support may require an upgrade.
Forgetting data protection: Newsletter tools, CRMs, website forms, and analytics tools all process personal data. That means you need proper consent, privacy notices, and often a data processing agreement (Auftragsverarbeitungsvertrag) with the provider.
What Freya Can Help Sort Out
Freya can take your business model and derive a small, sensible tool stack from it: what do you need now, what can wait, and what do you not need at all?
She can also compare providers, but she cannot give you a final review of your data protection obligations. If you use customer data, newsletters, or tracking, you should keep your privacy notices, cookie setup, data processing agreements, and tool terms in order.
Think Ahead: E-Invoicing and Data Exports
Invoicing and accounting tools should not just be convenient today. They should also support structured invoices, clean data exports, receipt storage, and collaboration with a tax advisor (Steuerberater).
E-invoicing (E-Rechnung) in the B2B space has been a relevant topic since 2025, with transitional rules in place. That is why it makes sense not to build new invoicing processes around PDF delivery alone.
Choose Website, Shop, and CRM Based on Your Customer Journey
A website builds trust and visibility. A shop automates product sales. A CRM helps you avoid losing leads and follow-ups. None of these is automatically the right first step.
Choose based on your customer journey: How does someone find you, how do they understand your offer, how do they enquire or buy, and how do you stay in touch?
Questions that may matter for your case
These questions help you classify the topic. In the start plan they are connected to your situation. You can also think through the answers beforehand.
- Do you want to acquire customers, manage them, or invoice them?
- Do you already have a website, or do you first need a simple online presence?
- Are you collecting email addresses or planning a newsletter?
- How many leads or customer contacts do you have per month?
- Which tools are you currently paying for privately, even though you use them for business?
- Are you processing customer data, tracking data, or payment data?

Helpful next step
Derive tool choice from the real workflow
Tools should support your next workflows: invoice, receipt, payment, customer contact, shop or website. Not every tool is needed at the beginning.
