For fiduciaries

The platform your mandates were waiting for.

Run thirty mandates without losing your sanity. Mast brings every client, every document, and every review thread into one workspace.

The unspoken frustration
I manage 30+ clients across four tools and a hundred email threads. By the time I get to the closing, I am exhausted before I even start.

Closing season as a fire drill

Books, banks, vouchers, audit threads. Each in its own tool, on its own timeline.

Client data quality you do not control

You cannot fix what is missing. You can only chase it down by email and hope it lands before month-end.

Audit handovers that swallow your week

The same questions every year. Different formats every time. Threads scattered across inboxes.

What changes

Three shifts. One workspace.

01

One workspace per mandate, one screen for all of them

Every client lives in their own Mast tenant with their own books and permissions. You switch with one click. No exports, no Dropbox folders named "v3 final FINAL", no toggling between four logins.

02

Your clients post their own primary documents

Your mandates upload invoices, receipts, and bank statements directly. Mast suggests categorisations and reconciliation matches for you to accept, edit, or reject. You stay in review mode, not data-entry mode.

03

Audit threads, not email threads

Auditor questions, follow-ups, and adjustments live in conversations attached to the right journal entry. Searchable. Permanent. Survives every handover.

A day with Mast

What it feels like in practice

  1. 08:30

    One inbox, every mandate

    You review what came in overnight across all 30 clients. No tab juggling, no separate logins. Anomalies are flagged at the top.

  2. 10:00

    A bank statement just landed

    CAMT.053 file imported automatically via SFTP. Mast already matched 80% of the lines. You confirm the rest in a few clicks.

  3. 11:30

    The auditor replied

    A thread on a Q1 marketing entry pings you. You answer in three lines, attach a board minute, the trail is preserved on the entry forever.

  4. 14:00

    Six expense receipts uploaded

    Your mandate took the photos on their phone. Mast suggests the category and the matching account. You confirm, adjust, and post the journal entries in two minutes.

  5. 16:30

    Period closes itself

    You hit close on one mandate. The period locks, depreciation schedules run, balance sheet and income statement auto-generate. Ready to share.

What this looks like

Three things you will use every day

Multi-mandate dashboard

Every client status, deadline, and exception in one screen. Filter by status, by closing date, by missing documents.

Client portal & inbox

Your mandates upload, you post. Granular permissions per role. Mobile receipt capture comes built in.

Audit thread system

Every question, answer, and supporting document attached to the journal entry it concerns. Search across mandates, periods, and auditors.
