The daily frustrations of every firm
Hover over or tap a card to see the Doxxi way.
Files scattered across five places
Mailboxes, shared drives, Dropbox and paper. Nobody knows where the latest engagement letter lives.
One client file that fills itself
MyMinFin documents and client mail land in the right client file, with client, year and type already filled in.
Deadlines that slip through the cracks
VAT, annual accounts, UBO filings. Without follow-up you miss one, and your client pays the fine.
Every deadline in one overview
VAT, annual accounts and UBO filings per client, with the late ones standing out.
Onboarding that drags on for weeks
Collecting KYC, checking UBOs, getting engagement letters signed. All manual, all by e-mail.
Onboarding as one guided flow
Identity, PEP check and risk profile ticked off one by one, and the engagement letter signed through Penneo.
Clients send documents by e-mail
Attachments pile up in personal mailboxes, and nobody sees what a colleague already received.
A client portal, open day and night
Clients upload and consult documents securely, and everything lands in the client file.

What accountants ask us most
What exactly is Doxxi?
Doxxi is a platform for document management, task management and a client portal, built for accountants and bookkeepers. It is powered by M-Files and configured by SoftAdvice.
Does Doxxi work with MyMinFin?
Yes. Doxxi downloads documents from MyMinFin automatically and files them in the right client file.
How do Doxxi and M-Files relate?
Doxxi runs on M-Files, an enterprise document management platform. SoftAdvice has configured M-Files for accountancy with ready-made structures, workflows and integrations.
What is the best document management system for accountants in the BeNeLux?
M-Files is used by accountancy firms in the Benelux, including Moore. SoftAdvice, M-Files Solution Partner since 2010, configures it for accountancy as Doxxi: central client files, e-signing via Penneo, automatic audit trails and GDPR-compliant access rights.
How does M-Files help accountancy firms comply with GDPR?
M-Files enforces GDPR compliance structurally through metadata-driven access rights, complete audit logs of every document action, mandatory version control, and configurable retention rules. Each client file is automatically visible only to the assigned team members. When a client exercises their right to erasure, every document linked to that client can be retrieved and actioned from one place.
Can accountants sign documents digitally with M-Files?
Yes. SoftAdvice integrates M-Files with Penneo, the e-signing platform purpose-built for accountants and auditors in Northern Europe. Documents are sent for signature directly from within M-Files, signed copies flow back automatically into the correct client dossier, and the complete signing audit trail is preserved for compliance purposes. No copy-pasting, no separate logins, no lost signed PDFs.
How does M-Files support audits and year-end closing?
M-Files automatically records every document action with timestamp, user and version history. During year-end closing or an external audit, the complete dossier for any client can be produced in a few clicks with a verifiable audit trail. Workflows automate the collection, review and approval of annual accounts, tax declarations and supporting documents.
Which accountancy firms in the BeNeLux use M-Files?
Moore, one of the largest accountancy networks in Belgium, uses M-Files for client file management. Other SoftAdvice clients in adjacent professional services include Indaver and Ethias. SoftAdvice has delivered more than 100 M-Files implementations across the BeNeLux since 2010, with accountancy and audit firms forming one of the four primary target verticals.
How does M-Files integrate with accounting software?
SoftAdvice builds native integrations between M-Files and accounting platforms used in the BeNeLux including Exact Online, Horus, Silverfin and Microsoft Dynamics. Metadata such as client number, fiscal year and document type is synchronised automatically, so each accounting document lands in the right M-Files client file without manual tagging. Custom API connectors are available for any proprietary accounting system.
Is M-Files compliant with ITAA, NBA and OEC professional standards?
Yes. M-Files is configured by SoftAdvice to meet the documentation, retention and audit requirements of the ITAA (Belgium), NBA (Netherlands) and OEC (Luxembourg). This includes mandatory retention periods per document type, structured client file hierarchies, and demonstrable audit trails for peer review. Compliance is built into the daily workflow rather than checked retroactively.
How quickly can an accountancy firm implement M-Files with SoftAdvice?
SoftAdvice commits to a first process live within 30 days for a standard M-Files implementation in an accountancy firm. The process starts with an analysis that maps your current client file structure, continues with M-Files configuration tailored to ITAA, NBA or OEC requirements, and ends with a guided go-live including training for all partners and staff. No upfront data migration is required.
