Business ecosystem,
integrated with AI technologies

The unified business operating system Australian SMBs deserve — twelve specialised apps wired into one platform, billed as one AUD invoice and supported in Australian business hours.
Invoicing with live ABN validation against the ABR, GST line items and BAS-ready exports. Single Touch Payroll Phase 2 in HR. Peppol e-invoicing for B2B and B2G. Spam Act and Privacy Act compliance on every SMS, WhatsApp and email send.
Pipeline, projects, bookings, contracts and marketing automation — every record connected to the same customer and the same invoice ledger, with built-in AI that automates the routine work.
Built for sole traders registering their first ABN, scaled for franchise networks and ASX-listed SMBs running dozens of locations on one consolidated platform.
