Forecast every shift.
Model 12-hour days, configured night/weekend differentials, and charge items from the pay rules you confirm.

Per-diem pickups, agency contracts, and travel assignments with different pay rules — compared side by side.
First responders
Plan around 24/72.
Enter long-cycle shifts, stipends, and the overtime threshold your employer confirms; review each estimate before relying on it.
Hourly · Gig
When the schedule swings.
Variable hours, two jobs, irregular paydays. Viably anchors them all to one cash-flow forecast.
01 / The product spine
Three inputs in.One answer out.
Everything on the surface points at the same question shift workers actually ask: am I safe this week, what changed, and what should I do next?
What changed
Every recalculation names the Viably data that changed — such as an entered shift, moved bill, or cash update.
No payroll login
Add shifts by hand or import supported files. Viably does not require an employer or payroll login.
The next move
Alongside the number, Viably suggests one next action based on the data available — for example, add a shift, review a bill, or update cash.
Built thumb-first
Mobile-first routes, pay receipts you can actually read, designed for a break-room glance.
