How it works
How OMS brings a firm onto one live screen
Context
OMS is Persmon's own platform for running a professional services firm in one place: clients, projects, approvals, invoices, payroll, compliance and meetings. Changes appear live for the whole team. A public demo runs on sample company data.
What we built
- A command centre with deadlines at risk, approvals and receivables
- Clients and a 12-stage project board
- Invoices, receipts, budgets and payroll
- Approvals with dual sign-off
- An access matrix and a full audit log
- Optional two-factor sign-in
