Every client company. Every deadline. One office.
You carry the books, filings, audits and paperwork of dozens of companies. Muhasib gives each one a living record — documents, engagements, deadlines, official mail, portal credentials and what is due next — instead of a shelf, a spreadsheet and a chat thread.

The whole practice, hanging off the companies it serves
Everything in Muhasib belongs to a client company — bookkeeping or audit, when the tax authority calls, the answer is one search away, not one colleague away.
Client companies as records
Each company is a living record: contacts, registrations, documents, notes and its connected mailbox — with your whole history of it in one place.
Deadlines that chase themselves
VAT, payroll declarations, annual filings, engagement milestones — recurring deadlines become assigned tasks with reminders and escalation. Nothing lives in someone's head.
Documents in, without the chase
Clients upload through their own portal, and requests show exactly what is still missing. No more “send me the invoices again.”
Official mail, from the record
A company's mailbox is read and answered inside its record, so correspondence with authorities and banks stays with the company it belongs to.
Portal logins, filled for you
Tax and social-security portal credentials are encrypted per company and filled straight into the portal by the browser extension — never a shared password sheet.
An AI agent that knows the client
Summarises a company's open threads, drafts replies and lists what is due — with the company's own context already in hand.
Engagements, evidence and confirmations — on the same record
Audit work is not a separate system. The engagement, its requests and the evidence that answers them hang off the client company, with an audit trail behind every action.
Engagements as structured work
Stages, tasks and deadlines per engagement, each assigned to a person with reminders and escalation. The status of the audit is visible, not asked around for.
Evidence that stays put
Received files attach to the client and the request they answer. Nothing lives in a personal download folder or an email thread only one person can find.
A real audit trail
Who saw, downloaded, revealed or changed what — logged with when and from where. You hold others to this standard; your tools should meet it.
Custom forms that fill other sites
So much of the work is the same client data typed into different websites: confirmation platforms, registry portals, regulator filings. Define the form once — then let the extension fill it.
Define once, fill anywhere
You build a custom form in Muhasib with the fields a site asks for — company name, registration numbers, fiscal identifiers, addresses, signatories. The values live on the client record, kept once and kept current.
On the site itself, the Arz Vault browser extension fills the form from the record in one action — the login from the encrypted vault, the fields from the client's data. No retyping, no copy-paste from a spreadsheet, no transposed digits in a registration number.
Accountable by design
- Every fill is logged — who, which client, which site, when.
- Credentials stay encrypted; the extension reveals them to the site, not to a shared sheet.
- Client scope applies: members fill only for the clients they may access.
Where it saves the most
- Tax authority and regulator portals.
- Bank confirmation platforms.
- Commercial registry lookups and filings.
- Any site your firm files on, month after month.
The form is yours to define — it works on any site, not a fixed list.
Ask about custom formsYour archive and your logins come with you
The desktop app brings your archive in
A practice with years of client folders does not start from zero. Arz Desktop imports your existing folder archive into client records, keeps versioned encrypted backups on storage you control, and mirrors client files to your machine.
The extension does the retyping
The Arz Vault browser extension fills portal logins from the company's record with a two-key quick-fill. Every fill is logged — who, for which company, when.

- Permissions and scope: what each member may do, and on which companies.

Working the same day you sign up
Register your firm
Create your organisation, invite the team, and set what each member may do and which clients they may do it on.
Add your clients
Bring in client records with their documents, portal credentials and mailboxes. Open the client portal when you are ready to request.
Start working
Filings, engagements, requests, evidence and deadlines all hang off the client they belong to — with the audit trail recording every action.
Built for data you are trusted with
Client files, credentials and correspondence sit in one place — so the boundaries around them are part of the platform, not an add-on.
Encrypted at rest
Credentials and files are encrypted with libsodium before they touch storage, and decrypted only in memory when someone with the right to see them asks.
Two-factor authentication
TOTP-based 2FA with organisation-level enforcement, so the firm can require it for every member rather than hope.
Full audit trail
Credential reveals, downloads, logins, fills and record changes are logged with who, when and from where — readable by the people accountable for them.
Tenant isolation
Every query is scoped to your organisation at the database layer, not by a filter someone has to remember to write.
Access down to the client
Permissions decide what a member may do; scope decides which clients they may do it on — by office, by selection, or everything.
Your data stays yours
Export is available at all times. Leaving is a decision you can make, which is the only thing that makes staying meaningful.
