Explore our FAQs to learn how Numonis works
For anything that remains unclear, please reach out and allow us to clarify.
How do I get started with Numonis?
Tell us about your business using the short form and an expert will contact you to walk you through our platform and service. We’ll match you with a dedicated accountant and, if needed, a payroll specialist, then guide you through account activation. At Numonis, there’s always a human on your side.
How long does onboarding take?
Once you provide the required documentation, the process is typically completed within 1 week. You’ll sign a service contract, make your first payment, and meet your assigned accountant. Platform access is set up in minutes once the contract is signed.
Can I use the Numonis platform with my own accountant?
Not at this time. Numonis is a fully managed service. Our platform and accountants work together to deliver the end-to-end outcome. We don’t currently offer a software-only plan.
We handle bookkeeping in-house but need advisory or tax support. Can Numonis help?
Yes. Our specialized advisory service plugs into your existing setup, strategic, tax, and localized guidance without taking over your bookkeeping.
I already have an accountant. How do I switch to Numonis?
We handle the migration for you. Send us your details so we can understand your situation and arrange the next steps; we’ll generally ask for a selection of documents to get started. Or, we can work directly with your current accountant to simplify the transition.
I’m just starting my business. How does pricing work for me?
Our autónomo plans start at 49€ per month excluding VAT. Choose the level of support that fits your needs, then send us your details and we’ll confirm the right setup with you.
Does Numonis offer VERI*FACTU-ready invoicing software?
Yes. Our invoicing software is prepared for VERI*FACTU and SII and available for FREE for all clients. The platform also includes invoice customization, analytics, client management, profit centers, and AI-assisted invoicing.
Is Numonis 100% digital?
Yes, fully digital and cloud-based. If you’re currently working with paper-based processes, we’d love to show you how switching to digital can simplify your day-to-day operations.
Is my data secure with Numonis?
Absolutely. We use bank-level encryption, hosted on secure European servers. We are fully GDPR-compliant and adhere to all applicable data protection regulations.
