Boss ×2.0, Manager ×1.5, Regular ×1.0, Newbie ×0.5—calculating 4 tiers by hand and fighting over fractions
Just create categories and choose ratios. Any number of tiers—rounding to the nearest 100 is automatic. Surplus is shown instantly, so no one feels cheated.
"That person didn't get the drink package"—one exception and the whole calculation falls apart
Set a fixed amount for the exception (e.g., ¥3,000 fixed). The rest is auto-distributed among other members. No more broken math.
Sending each person their amount on LINE is tedious, and then comes "Why this amount?"
Just share one URL. Everyone can see their amount and the ratio logic on their phone—zero explaining needed.
