Group delivery orders have hidden fees that make 'fair' splitting complicated. Someone always ends up subsidizing.
$94 DoorDash.
$18 delivery fee. 6 people.
You ordered a $12 burrito. You paid $19.
The scenario
Six coworkers order lunch through DoorDash. You get a $12 burrito. Others order $15-20 entrees. The subtotal is $94. Then come the fees: $4 delivery fee, $8 service charge, $6 tip. Total: $112. Split six ways? Everyone pays $18.67. But your $12 burrito just became a $19 meal—a 58% markup. Meanwhile, your colleague's $20 pad thai only increased to $19—a 5% discount, effectively. The fees are proportionally larger on smaller orders. When those fees get split equally, small orders subsidize large ones. It's the salad-vs-steak problem, delivered.
The solution
splitty reads DoorDash receipts. Every item gets assigned to whoever ordered it. Fees and tip distribute proportionally: your $12 burrito carries less of the $18 in fees than your colleague's $20 pad thai. Your actual share: $14.50 (your burrito + proportional fees). Not $19. That's $4.50 saved on a single lunch order. Over a year of weekly group orders, that's $234 you would have lost to 'even' splitting.
