Payroll, accounting, and signing — for Singapore SMEs, in one login.
Critical Mass Cloud runs HR & payroll, accounting, and e-signatures together, built for Singapore compliance from the ground up — CPF, IRAS, GST, InvoiceNow.
Stop stitching tools together
Most small firms run payroll in one app, books in another, and chase signatures in a third — then spend month-end reconciling all three. Critical Mass Cloud puts them behind one login, sharing one source of truth for employees, invoices, and signed documents.
Built for Singapore, not adapted to it
CPF and SDL contributions, IRAS AIS submissions (IR8A), itemised payslips to MOM standards, GST, and InvoiceNow e-invoicing are handled natively — not bolted on after the fact.
Three modules, one platform
Your data, properly isolated
Critical Mass Cloud is multi-tenant with schema-per-tenant isolation — your business's data is separated at the database level, not just filtered by an ID. Built to PDPA expectations.
Schema-per-tenant database isolation
Who it's for
Singapore SMEs of roughly 5 to 50 staff who've outgrown spreadsheets and separate point tools and want payroll, books, and signing in one place.
