The advantages of Online Accounting

Write professional invoices

You can create professional invoices easily with the design templates on offer. You can adjust your invoice until it suits your company's style, and upload your logo. Online Accounting will also build a database of customers, saving you the effort of entering the same data for each order, and will notify you if any necessary information is missing from the document.

Scan and track your expenses

You choose how to enter your expenses: scan, drag and drop, or use email forwarding. You can simply send your invoices to the tool via email, and our bookkeeping software scans the documents and transfers the information to the relevant expense account. This keeps your accounts automatically updated, so you can easily keep track without entering data manually.

Business overview

Once your income and expenditure are in the tool, your tax amounts are estimated and everything is ready for your accountant. This means you have a comprehensive overview of your business whenever, and wherever you like.

FAQs - Frequently asked questions
Are you self-employed and looking for a way to make your bookkeeping system easier? Whether you're a freelancer, startup founder or small business owner, we have just the option for you. The 1&1 IONOS bookkeeping software is powered by sevDesk. It is a cloud-based software, so no extra software is necessary. It allows you to take care of all your paperwork anywhere you like. There are three options for your online bookkeeping: 1&1 IONOS Invoice, 1&1 IONOS Accounting or 1&1 IONOS Inventory Manager. Each option offers a different range of functions: 1&1 IONOS Invoice is the basic program, whereas 1&1 IONOS Inventory Manager is the fully equipped professional program. The functions included in each of the three options vary slightly. Have a look at the overview above in order to see exactly what each option entails and to choose which functions may suit you and your business best.
Yes, absolutely! You can of course create invoices manually, but it may be quite time consuming. With cloud accounting software, you can create professional invoices with just a few clicks of the mouse. Data such as the customer's receipt or consecutive invoice numbers need only to be entered in once and then the 1&1 IONOS accounting system fills the rest out automatically for you. The bookkeeping system therefore saves you from spending too much time on tedious tasks. Accounting does not always have to take such a long time; opt for online accounting in order to focus your attention on your core business, where it's really needed.

The correct legal information is crucial, and we recommend that you consult with a tax advisor to make sure that all your invoices are legally compliant before issuing. However, the visual representation of your company also matters. The design of your invoices is an important aspect. With the 1&1 IONOS bookkeeping system, you can design your invoices yourself: layout, logo, and letter paper – everything can be individually customized. By choosing the 1&1 IONOS accounting software powered by sevDesk, you will benefit from an integrated postal interface, whereby you can send out your invoice via post with just one click. Gone are the days of buying envelopes and stamps and waiting in line at the post office to send off your invoice. For those who would rather send out an invoice via email, this is not a problem. A message will automatically be sent to your email address with a PDF of the invoice attached to it. All you need to do then is click "Send".

If there are any open invoices, you can view these at a glance in the bookkeeping software thanks to the integrated bank interface. Through automatic invoice verification, the online accountant will show which invoices are paid and which are still open.

Businesses do not always run smoothly – as a self-employed person you need a good basic knowledge of the dunning process. With the business accounting software powered by sevDesk, you can simply generate and send out payment reminders (be sure to check with a professional tax consultant to make sure that they fulfil the requirements to be legally binding); this way, you'll give your customers a friendly reminder about their outstanding invoices, but with less effort and time.
Online bookkeeping for freelancers and small businesses has never been easier: simply take a photo of all the receipts that are relevant to your business. This can be easily taken care of with the sevDesk app, available for both iOS and Android. When you take a photo with the smartphone app, it will automatically appear in your account. This practical function makes dealing with receipts a lot less complicated and ensures that none of them slip through the net.

Using the online accounts software, simply scan all your documents and then use the drag and drop function to place these documents into your account.

If you are looking for a program with automatic document recognition, then look no further. The 1&1 IONOS accounting software has a text recognition function that will make your work load even lighter; with the help of intelligent algorithms, the software will sort your receipts automatically. The program fills out important fields such as the date and value. You therefore do not have to worry about special circumstances such as guest invoices or hospitality receipts. Using integrated search masks, the 1&1 IONOS accounting software recognises all important information and records the documents accordingly.
Yes, it is possible to create as many different cost centers as you like. When you're working with a variety of projects and different departments, accounting can quickly become confusing. With the accounting software for small businesses and freelancers, you can view everything according to the different departments (for example: sales, marketing or production). Creditor and debtor account keeping can be quickly and easily taken care of.
The days of flipping through individual bank statements are well and truly over. Simply connect your online bookkeeping software directly to your account. The 1&1 IONOS accounting software is supported by a great number of banks. As long as the two are connected, the software can recognise which incoming payments belong to which invoice. This way, you can quickly see at a glance which invoices have been paid and which are still open. Your customers or clients also have the option of settling up their bills directly via 1&1 IONOS online accounting. The bookkeeping software takes care of everything that's important; you can save both time and money by connecting with your online banking.
Online accounting with 1&1 IONOS saves time and energy for all involved. In particular, it makes work easier for freelancers and small business owners who often have no business partners or employees.

Does the 1&1 IONOS online bookkeeping make revenue calculations easier?

Online accounting has a positive impact on the comparison of your revenue and expenses: both lists are recorded and used as a basis for the revenue calculation, which highlights your company's exact profit. Based on your revenue and expenses, the 1&1 IONOS bookkeeping software automatically generates detailed accounting reports. You can also set the type of taxation you wish to have on your invoice – either actual receipts taxation or debit taxation. Actual receipts taxation is particularly suitable for freelancers, as it allows them to pay the tax after they receive their payments. Make sure to check which type of taxation you are entitled to in advance. Note: if you use the balance sheet accounting method, you can still benefit from using 1&1 IONOS online bookkeeping powered by sevDesk.

Can 1&1 IONOS accounting software replace a tax consultant?

No, the software is designed to improve communication with your tax consultant, not replace them. Since 1&1 IONOS does not provide any tax advice, working with a tax consultant is still absolutely essential, especially for freelancers and small businesses. This way, you will have support from professionals at every stage and prevent any errors from occurring. 1&1 IONOS's software easily accommodates communication with your tax advisor, whom you should always consult to ensure that your invoices are legally compliant.

The 1&1 IONOS bookkeeping software is designed to include your tax consultant throughout the accounting process, providing them access to the account so that they can see all documents as and when they want. This saves both you and your tax consultant time. Note: if you do not want your tax consultant to see everything, simply reset your permissions. For example, you could allow your tax consultant access to all the invoices, receipts, payments and evaluations but not each specific contract. This allows you to protect data you want to keep confidential.
1&1 IONOS online bookkeeping is software intended especially for freelancers and other self-employed people. Because it is cloud-based, users can access it from anywhere they like – simply start your browser, log in and get going! Desktop computers, tablets or smartphones: it doesn't matter which device you use.

With 1&1 IONOS online accounting powered by sevDesk, we save you a lot of time and energy. The wide variety of functions are designed to make your bookkeeping as easy as possible allowing you to focus on your core business and do your accounting in record time.

As well as saving you time, the 1&1 IONOS online bookkeeping ensures that you have an overview of everything. Open invoices, profits, losses – you'll always have everything at a glance with the help of the integrated dunning system. Provide your customers with a quick and friendly reminder that their invoice has yet to be paid. This method will ensure quicker payments and therefore a higher liquidity. Don't leave anything to chance!

Many people feel daunted by accounting because of the various possible mistakes that can be made – this especially applies to freelancers and small businesses. In addition to this, there are plenty of legal issues to pay attention to. As a rule, we recommend using your 1&1 IONOS software in conjunction with a tax consultant, just to make sure that everything you are doing is legally watertight. Thanks to regular updates, the program can quickly adapt to constantly changing conditions.

Many accounting software users praise it for its digitization of accounting transactions and for its reduced paper waste. The idea of a paperless office is fast becoming a reality – it's no wonder that workflows are improving.
Yes, of course. It's the perfect accounting software for mac.
Yes, your personal data will be handled with the utmost care. Your data will be sent to one of our SSL-secured data centers where it will be safely stored. Regular back-ups also increase the security levels provided by 1&1 IONOS accounting software. At the end of the contract, 1&1 IONOS will delete the stored customer data.
