A full walkthrough of the Finance App — from multi-business setup to invoicing, banking, and reconciliation.

Everything a finance team needs

Built for real accounting workflows — not a generic dashboard with finance labels slapped on.

Invoices & Quotes

Create, send, and track professional invoices and quotes. Automated reminders, partial payments, and PDF exports built in.

Bills Management

Record and manage vendor bills, track due dates, and maintain a full audit trail of all outgoing payments.

Banking & Plaid

Connect real bank accounts via Plaid for live transaction feeds, automatic categorisation, and reconciliation.

Reconciliation

Match bank transactions against recorded entries with a side-by-side reconciliation workflow that flags discrepancies instantly.

Financial Reporting

P&L statements, balance sheets, cash flow reports, and category breakdowns — all filterable by date range and account.

Multi-Business

Manage multiple companies under a single login. Switch context instantly and keep finances fully isolated per entity.

Clerk Authentication

Enterprise-grade auth powered by Clerk — social logins, MFA, session management, and role-based access control.

Multi-Tenant SaaS

Each business operates in a fully isolated tenant environment with dedicated data, branding, and access controls.
