Contaro vs Stripe

Contaro

Accounting software for self-employed people and small businesses in Austria

Contaro is accounting software for self-employed people, sole proprietors and small businesses in Austria, covering invoicing, receipts, expenses and tax preparation in one German-language tool. It is built for the Kleinunternehmer and Selbständige who need their books to be correct but have no intention of making accounting their job. Invoices are created from customisable templates with your own logo and colours, and carry the österreichische Pflichtangaben — the mandatory fields an Austrian invoice must show — along with proper USt handling, so compliance is the default rather than something you check afterwards. Recurring invoices can be issued weekly, monthly or quarterly, and overdue items feed a dunning workflow instead of being tracked in a spreadsheet. The receipt side leans on AI: photograph or upload a receipt and Contaro extracts the supplier, date and amount and proposes an expense category, which you confirm before it saves. A built-in assistant called Taro answers questions against your own data and drafts invoices, reminders and credit notes. A Gmail integration finds and files invoices that arrived by email. At year end it produces the E/A-Bericht and a complete tax package for your Steuerberater, exports to PDF and CSV, and supports XRechnung XML for recipients who require it. Pricing starts with a 14-day Pro trial that drops automatically to a free tier of five invoices a month, so there is no cancellation to remember. Data handling is DSGVO-compliant.

Stripe

Payments infrastructure for the internet

Stripe is payments infrastructure delivered as an API, and it is the closest thing the internet has to a default. Its founding insight was that accepting money online was a compliance and integration project, and that it could be reduced to a handful of lines of code and a dashboard. The surface is much larger than card processing now. Payments and the hosted Checkout or embeddable Elements handle the transaction. Billing runs subscriptions, invoicing, proration and usage-based pricing. Connect powers marketplaces and platforms that need to pay other people. Radar handles fraud, Tax calculates rates, Issuing produces cards, Terminal covers in-person, and Atlas will incorporate the company in the first place. For most software businesses, Stripe is not one vendor among several but the financial substrate the product sits on. The honest limitation, and the one founders discover late, is that Stripe is not a merchant of record. You are the merchant. That means sales tax, VAT and their registration and remittance obligations are yours, in every jurisdiction where you cross a threshold. Stripe Tax will calculate and file in many places, but the liability and the registrations stay with you. This single fact is the main reason a solo SaaS founder selling worldwide often picks Paddle or Lemon Squeezy instead. Worth knowing too: accounts in higher-risk categories can face reserves or abrupt review, and support is documentation-first rather than phone-first. Pricing is transparent and usage-based, with no setup fee and no monthly fee on the core product. US online card payments are 2.9 percent plus 30 cents per successful domestic charge. Billing is either 0.7 percent of billing volume pay-as-you-go, or from 620 dollars a month on a one-year contract. Connect is included with standard Payments pricing. The comparison set: Paddle and Lemon Squeezy are merchants of record, taking a larger cut and taking the tax burden with it; Polar is the newer open-source take on the same idea aimed at developers; Braintree and PayPal trade developer experience for consumer trust; Adyen and Checkout.com win on rates at genuine scale; Square leads in-person; and Chargebee or Recurly add a billing layer on top of whichever processor you choose. Choose Stripe when you want the best developer experience in payments and you are prepared to own tax compliance yourself, or to bolt on a tool that does.
