FAQ about our online accounting software

To be able to use our online agency services for freelancers, you must meet a series of requirements:

  • Be residents in Spain, which means that you live more than 183 days in Spain and therefore must declare your income to the Treasury. *Unless you can qualify for the impartial regime (Beckham Law)
  • Be a resident in any area of the country, except the Canary Islands, Ceuta, Melilla, the Basque Country or Navarra.
  • Be professionals in those IAE categories that pay taxes under the simplified direct estimation regime.
  • Not having employees.
  • Not having a store or other establishment open to the public. (If you sell goods):
  • Not operate with cryptocurrencies.

Our online accounting solution has two key elements: the online platform and our team of expert managers.

  • Online platform. Thanks to it, you can manage your invoices, expenses and accounting directly. We have automated many of the processes (VAT and income tax calculation, for example) to make everything easier. In addition, you will be able to track your taxes and finances in real time.
  • Expert accountants. We'll assign one to you as soon as you register with Xolo. Your personal manager will guide you through the process, file your taxes, answer any questions you may have and recommend what's best for your business.

Simply register with Xolo and select the "I'm already autónomo" option in your control panel. Then you’ll need to upload your registration documents (we hope you have them handy) and wait a maximum of 24 working hours until you receive an email with steps to follow.

And if you don't have the papers at hand, don't worry. We will contact your previous manager and will solve it in moments.

Depending on the plan you choose, you will have access to a series of services for your freelance activity. In addition, you can always hire another service or procedure if it is not included in your plan.

These are some of the most requested services:

  • Ordinary invoice: a complete invoice that includes all legally required information.
  • Simplified invoice: an invoice in which it is not necessary to include all the data of our client. You’ve likely heard it referred to as a ticket.
  • Credit note: an invoice that corrects another invoice already issued. As invoices cannot be deleted, every time you make a mistake you will have to issue a rectification.
  • Proforma invoice: the invoice that is given to the customer before delivering or finalizing the service. It has no fiscal value.
  • Recapitulative invoice: an invoice that includes several invoices to the same customer with the value of all the services rendered.
  • Electronic invoice: the evolution of the paper invoice. An invoice that requires signature through digital certificate.

You can check which services are included in each plan and the price of each additional service in our Pricing page.

Don't worry. We will call you, so you can explain the details of your case, and we can recommend a customized solution.
