The slabs are public. The maths shouldn't be a secret.
Every tool on this page runs the same calculation Naasflow uses inside the product. We open-source the maths because every payroll team should be able to double-check a number — whether they're a customer or not.
No signup, no email gate, no “unlock the result” drip. Type a number, get the answer, walk away if you want to. If you ever want the rest of the platform, the demo is one click below.
