Accept and pay out via PayNow and FAST in Singapore
Singapore’s FAST rail and PayNow proxy addressing made account-to-account payment the norm for consumers and businesses alike — QR or mobile-number checkout that clears in seconds at any hour. Singapore is also one of ApeX Payment’s licensed home markets, which makes the compliance path for SGD collections unusually clean.

Collecting and paying out.
Both directions of the flow, on one balance.
Pay in · PayNow / FAST
Pay-in flow: present a PayNow QR or UEN/mobile proxy; the customer pays from any FAST-connected bank app. Confirmation is a final interbank credit with a unique reference — no interchange stack, no card declines. ApeX reconciles by reference in real time and webhooks your systems the moment funds land.
Pay out · FAST
Payout flow: disburse SGD to any FAST-connected bank account 24/7 — by account number or PayNow proxy. Ideal for supplier settlements, contractor payments and platform refunds in one of Asia’s densest banking markets.
Settle to stablecoin treasury.
Keep your SGD balance for local spend, or convert to USDT / USDC and withdraw on-chain — the corridor where stablecoin settlement usually pays for itself.
One balance, two worlds
Settlement angle: ApeX operates under a Singapore licence, so SGD collections come with locally issued compliance documentation. Settle to USDT/USDC for regional treasury, or hold SGD — both legs stay inside a screened, documented flow.
Payout rails covered

Common questions.
What is the difference between FAST and PayNow?
FAST is the instant interbank transfer rail; PayNow is the proxy-addressing layer on top that lets customers pay to a mobile number, NRIC or company UEN instead of a full account number. ApeX supports both.
Can I pay out to a company by UEN?
Yes — PayNow Corporate accepts UEN as a proxy, which is how Singapore businesses pay each other. Payouts confirm in seconds around the clock.
Is SGD collection compliance-heavy for foreign entities?
Less than you would expect: ApeX holds a Singapore licence, so the KYC/KYB, sanctions screening and record-keeping are handled locally under MAS-supervised partners.
