Your bank, connected to your accountant

Your accountant and your data, in one unified workspace
Use the Numonis platform to message your accountant, send and store documents, issue certified invoices, and monitor your business health.
It comes with every Numonis plan.
-
Message your accountant
Send and receive messages through the platform or by email, whichever is easier. Every message and file stays in the same conversation.
-
Share documents how you prefer
Upload them or send them from the tools you already use. They’re kept safe and filed in order, so your accountant can record them in your accounts.
-
Send invoices from the same platform
Create and send an invoice in a couple of minutes, ready for VERI*FACTU. Your accountant sees it straight away, so there’s nothing to forward.
-
See how the business is performing
Bank balance, income, what customers still owe you and how the months compare, updated with every transaction.

10 / FAQ
What people ask before joining Numonis
How do I get started with Numonis?
Start with a short call to tell us what you need. We then review your case, introduce you to your accountant and coordinate the handover and platform setup.
How long does it take to get started?
Most clients are fully set up in under two weeks. In that time we collect what we need from your previous accountant, so your filings carry on without a gap.
Can I use the Numonis platform with my own accountant?
Not at the moment. Numonis is a service: the platform comes with your accountant, and the two work together. We don’t offer a software-only plan.
We handle bookkeeping in-house but need advisory or tax support. Can Numonis help?
Yes. Tell us where you need a hand and we’ll suggest how our accountants, tax advisors, payroll and legal specialists can work alongside your team.
I already have an accountant. How do I switch to Numonis?
We do the handover for you. We ask your previous accountant for the documents, past filings and access we need, and agree who files what so no deadline is missed. You don’t have to chase anyone.
