A chat thread is great for talking and terrible for remembering what was paid.
Most sites run on a WhatsApp group and a diary: photos, voice notes, and "paisay bhej diye" scattered through a chat nobody can total. It works until you need the one figure that matters and have to scroll a week to find it.
TameerBook keeps the quick capture you like — add a payment or a cost in seconds — but turns it into a record you can actually read: balances, job costs and wages, not a thread.
