AyayByay — Brand Kit v1 · 2026

One-page reference for anyone making AyayByay materials — ads, banners, decks, print.

1 · The name

AyayByay — always written with capital A and capital B, one word. Bangla: আয়-ব্যয়.

Say it: “A-yay, B-yay” (আ-ইয়ায় বি-ইয়ায়). আয় = income · ব্যয় = expense — the two words every shopkeeper lives by.

❌ Never: AYAYBYAY, ayay byay, Ayay-Byay, AayByay.

আয়-ব্যয়ের হিসাব, এক অ্যাপে। (primary)

Income in. Expense out. Everything counted.

দোকানের পুরো গল্প দুটি শব্দে — আয় আর ব্যয়।

Built in Bangladesh. Made for Bengali business everywhere.

6 · Voice

Bangla-first, respectful (আপনি), plain words a shopkeeper uses. English as support, never jargon. Honest — no fake numbers, no fake urgency. Warm, like a helpful nephew who knows computers.
