Start-up accounting: A comprehensive guide for young companies
Accounting is just as required by law for start-ups as it is for established companies. At the same time, well-founded and meaningful figures can help to support your entrepreneurial success in a targeted manner. It is therefore useful to keep an eye on accounting right from the start-up phase.
In the following sections, we will show you what is important and whether it makes more sense to take over or outsource the accounting of your start-up yourself.
You'll learn everything you need to know — from the basics to tools that can make your bookkeeping easier.

Why accounting is crucial for start-ups
In order for your company to be able to grow in the best case scenario and to keep track of current developments at all times, even as a start-up, you need well-structured accounting.
The earlier you establish clear processes, the easier it is usually to uncover savings potential, improve liquidity and make well-founded decisions.
In addition, meaningful and up-to-date accounting is also important when it comes to submitting funding applications, holding talks with banks or convincing investors, for example.
If you look into your start-up's accounting department at an early stage and seek advice when needed, you protect yourself from unpleasant surprises — both internally and externally. This creates an important basis for the further development of your company.
EUS vs. double bookkeeping: What should start-ups choose?
Choosing the right accounting method is crucial in order to work in compliance with the law right from the start and not to risk unpleasant surprises at the tax office. As a start-up, depending on the legal form and turnover, you either have the choice between surplus income statement (EURE) and double bookkeeping or are legally bound to one of the two options.
For example, if you want to attract investors or scale your company in the long term, double bookkeeping is often worthwhile. Although it is more complex, it offers more transparency about assets, liabilities and cash flows — both for internal decisions and for external financiers.
The following overview shows you how EURE and double bookkeeping differ.
EÜR
Disadvantages of digital accounting
- Easier method
- It is usually sufficient if your company is not accountable
- Ideal for solo self-employed people and smaller or sole proprietorships
- More complex
- Provides a more detailed overview of your financial position, liabilities and cash flow
- Corporations, such as GmbHs or KGs, are required by law to keep double-entry accounts

Do your own bookkeeping in a start-up or outsource it: What is really worthwhile?
The decision whether to do your bookkeeping yourself or hand it over to a tax advisor has a direct impact on time, costs and control. While you retain full transparency about your figures when doing it yourself, you benefit from professional support and noticeable relief in everyday life.
Which solution best suits your start-up depends primarily on your expertise, available time and budget.
The following table shows you the advantages and disadvantages of doing your own bookkeeping and outsourcing the corresponding tasks.

benefits
drawbacks
Do your own bookkeeping
- Comparatively cost-effective, as there is no need to spend on external tax advice
- You retain full control over your figures and don't have to request evaluations first
- You get to grips with accounting at an early stage and can quickly familiarise yourself with the subject if necessary
- There are numerous tools that are also suitable for founders who have had little contact with the topic so far
- The risk of errors is comparatively high, especially when the necessary expertise is lacking
- The tasks can be very time-consuming, so that you are repeatedly distracted from your core business
Outsource consulting
- Tax advisors have the necessary expertise to provide you with comprehensive support based on current legislation
- You save time because you can focus more on your business
- You benefit from more security when it comes to tax and accounting issues
- Tax advice is available to you even with complex issues and helps your company grow
- Working with a tax advisor causes additional costs and burdens your budget accordingly
- You depend to a certain extent on an external service provider, particularly if they manage your documents and processes
Founders who want to save money during their start-up phase often decide to outsource only part of their accounting, for example by pre-sorting and/or pre-booking documents. This is how they relieve the tax advisor, which then has to invest less time.
Bookkeeping software for start-ups: Which tools are suitable?
The right software is an important component for efficient accounting with as few errors as possible. It saves time, reduces manual work and creates transparency about your finances.
Which solution is best for your start-up depends on how complex your processes are and whether you organise your bookkeeping yourself or working with a tax advisor. The following tools are among the most popular solutions for founders and small businesses — from entry-level solutions to scalable all-in-one systems.
integral
Integral is aimed at companies that want to organize their accounting and tax processes via an all-in-one solution. The platform combines tax advice, bookkeeping and payroll. It is particularly suitable for founders, start-ups and small and medium-sized companies that value automated processes and personal support.
Since accounting, payroll and tax advice are bundled together, this solution requires fewer interfaces. Personal support is also available, which you can contact if you have any questions.
sevDesk
sevDesk is a cloud-based accounting and invoicing software that is used particularly frequently by start-ups, small companies and self-employed people. With the solution, you can, among other things, create invoices, offers and reminders as well as upload receipts via an app. Depending on the tariff, the tool can also be connected to your inventory management system. DATEV export and tax consulting access are also available.

Bookkeeping for national and international start-ups: What is the difference?
Whether your start-up operates exclusively in Germany — based in Berlin, for example — or also has international customers and business partners directly influences your accounting requirements.
Start-ups focused on the German market
If your company operates nationally, the German requirements of the Commercial Code (HGB) and the Sales Tax Act (UStG) apply. You are required to submit advance sales tax returns on time, correctly calculate profits and archive all receipts in accordance with GoBD. Clearly structured accounting saves you time and helps you meet tax deadlines securely.
Start-ups with an international focus
As soon as you work across borders, there are additional requirements:
- different sales tax regulations, for example the reverse charge procedure
- Currency conversions and country-specific invoice formats
- Where applicable, tax registrations abroad
- adapted reports for international investors
Even if you currently only work nationally, it can make sense to make your accounting scalable right from the start. This allows you to react more quickly in the event of later growth or international expansion without having to completely redesign your processes.
If you are planning to become active outside Germany in the long term, it makes sense to work early on with a tax consultancy that has experience with international clients. This saves time later and can avoid time-consuming changes as your start-up grows.
Practical tips for start-up bookkeeping
Well-organized bookkeeping saves time, reduces errors and ensures that you always have an overview. It is crucial that your processes comply with GoBD guidelines. This means that they must be comprehensible, complete and timely.
The following tips will help you to organize your bookkeeping efficiently and in compliance with the law:
- Enter documents immediately: Upload invoices and receipts as quickly as possible or scan them directly with accounting software. This keeps your figures up to date and keeps you in control of your spending.
- Keep an eye on deadlines: Create an overview of all relevant dates — such as for advance sales tax returns, annual financial statements and advance payments — and schedule them firmly in your calendar.
- Use automation: Modern accounting software can automatically recognize receipts, reconcile payments and remind you of deadlines. This saves time and reduces sources of error.
- Observe legal form: Find out which tax deadlines and requirements apply to your type of company. This ensures that you meet all requirements.
- Include professional advice: If you are unsure, get help from tax advice. She can advise you, optimize processes and ensure that your accounting meets legal requirements.
Experienced tax consultants can also help you simplify internal processes and identify automation potential. In this way, your accounting remains efficient even as your start-up continues to grow.

Frequently asked questions about Start-up accounting
Accounting for start-ups includes the systematic recording of all financial transactions. It creates transparency about the economic situation, forms the basis for tax returns and liquidity planning, and supports well-founded business decisions. With well-organized accounting, you avoid mistakes and create an important basis for growing your business.
Whether you do your bookkeeping yourself or handing it over to a tax advisor depends on your knowledge, available time and budget. If you do the bookkeeping yourself, you save costs, but you have to invest more time. By outsourcing accounting, you reduce the risk of errors and can concentrate more on your core business. If required, you will also receive professional support and individual advice.
The right accounting software should be scalable so that it supports you reliably even after the start-up phase. Many providers offer features such as automatic document entry, location-independent work and interfaces to bank accounts and other applications. The earlier you opt for an integrated solution, the smoother your financial management in everyday life.
Start-ups in Berlin may benefit from regional funding programs and are subject to German tax regulations. Anyone who operates internationally must also comply with country-specific tax requirements, convert currencies and, in some cases, keep multilingual documentation. Invoice formats and tax regulations also differ from country to country.
According to Section 241a HGB, there are certain thresholds for exemption from accounting requirements: a turnover of up to 800,000 euros and an annual profit of up to 80,000 euros.
“Individual traders who have no more than 800,000 euros in revenue and 80,000 euros in net income each on the closing dates of two consecutive financial years do not need to apply Sections 238 to 241. In the case of a new foundation, the legal consequences occur even if the values in sentence 1 are not exceeded on the first closing date after the new foundation. ”
Corporations such as GmbH or AG are required to use double bookkeeping regardless of turnover.
