Here are widely used Sri Lanka mobile banking / payments apps that support bill payments (utility, telecom, credit‑card, government and many third‑party billers). I list each app with its key bill‑payment capabilities and an official source.

• Bank of Ceylon — B App (and SmartPay): pay utility bills, credit cards; bill presentment, add billers, immediate/scheduled/recurring payments; LankaQR support via SmartPay. (boc.lk)

• Commercial Bank (ComBank Digital / ComBank Q+): in‑app bill payments across many categories (telephone, electricity, water, insurance, education etc.), bill number validation and LankaQR support. (combank.lk)

• HNB — HNB SOLO / HNB Digital Banking: pay 100+ billers (utility, insurance, school fees), save billers, schedule/recurring payments; LankaQR and biometric login supported. (hnb.net)

• Sampath Bank — Sampath WePay & Sampath Vishwa: digital wallet and internet/mobile banking that let you pay 100+ billers, schedule payments, LankaQR/QR payments and pay via linked cards/accounts. (apps.apple.com)

• NDB — NDB NEOS: pay utility bills and credit cards, mobile recharge, schedule recurring payments, CEFTS/real‑time transfers and NEOSPay (LankaQR) integration. (ndbbank.com)

• DFCC Bank — DFCC ONE: mobile “super‑app” with real‑time transfers, credit card and account bill payments and scheduled payments. (apps.apple.com, enbsl.lk)

• Dialog / Genie (digital wallet): Genie (Dialog) wallet and Genie/Genie Business let users pay many billers, link bank accounts/cards/eZ Cash, and pay via LANKAQR or in‑app biller lists. (Useful if you prefer a bank‑agnostic wallet that supports many billers.) (genie.lk)

Notes and tips

• Most major bank apps support adding billers, saving templates, one‑time and recurring (scheduled) payments, and LankaQR or national QR payments (LANKAQR / JustPay / CEFTS) for merchants and many billers. See the bank’s app page or FAQ for the exact biller list and fees. (boc.lk, combank.lk)
• Fees and per‑transaction limits vary by bank and by biller (e.g., some utility bill payments carry a small fee). Check the bank’s tariffs/SmartPay/NEOS pages before transacting. (boc.lk, ndbbank.com)

If you want, I can:

• Narrow this to apps from a particular bank or telco, or
• Check whether a specific biller (e.g., CEB, LECO, Water Board, a school or insurer) is supported by a specific app — tell me the biller and I’ll look it up.
