Roster a week by colour, not by clicking
Putting the right people on the right jobs used to mean opening every event and editing it. Colour the events, and the crew goes on all of them at once.
Assign by colour code
Each crew has a colour. Every event in that colour gets that crew, across a whole week in one pass.
Leads and assistants
Add assistant staff alongside the lead worker where a job needs two, without breaking the rest of the roster.
Per-staff calendars
Everyone sees their own day in the calendar they already carry, and a staff directory keeps the details in one place.
Assigned in one pass. Change a colour, and the crew changes with it.
The same events become your invoices
Reminders are half of it. The jobs already in your calendar carry everything an invoice needs — so nothing gets retyped, and nothing gets missed.
Your template, your branding
Invoices are real documents in your own Drive, built on the template you already use — not a rigid format someone else designed.
Every client type, invoiced its own way
Private jobs, company clients with group codes, and funded-care clients run side by side. Each gets the right rates, the right format and its own numbering.
Reconciled when you get paid
Drop in a remittance PDF from any payer and it matches line by line against your logs by invoice number, marking off what has been paid.
Or let the job invoice itself
The field portal turns a photo of finished work into an invoice in the client's inbox, while your crew is still on site.
Crew uploads a photo
From the field portal on their phone, the moment the job is finished.
Matched to the event
The photo is tied to the calendar event it belongs to, and the invoice is built from those details.
Emailed to the client
Sent from your own Gmail to the right recipient — about thirty seconds, start to finish.
Built for professionals who need reliability
Trades, field services, NDIS and aged care providers, clinics — anyone whose work already lives in Google Calendar.
Trades & field services
Roster crews onto a week of jobs by colour code, arm every reminder in one pass, and invoice from the same events.
Service businesses
