Quick Answer: HitPay is the leading invoicing and payment platform for Singapore SMBs, supporting PayNow, GrabPay, ShopeePay, cards, and BNPL with zero monthly fees and next business day SGD payouts. Stripe and Airwallex also serve Singapore merchants but are better suited to developer-led or globally-focused teams. HitPay is MAS-licensed (PS20200643) and free to sign up, with approval in 1–3 business days.

Invoicing is a cash flow problem before it is a software problem. Singapore SMBs — from Tanjong Pagar service firms to Bugis boutique retailers — routinely wait 14–30 days on unpaid invoices. The right invoicing tool closes that gap by embedding a payment link directly into the invoice, so clients pay on the spot rather than by bank transfer later.

The Monetary Authority of Singapore (MAS) requires all payment service providers operating in Singapore to hold a valid licence under the Payment Services Act. That regulatory baseline matters when choosing an invoicing platform: unlicensed tools may accept card numbers but cannot settle funds directly into a Singapore bank account without a licensed intermediary.

This comparison covers three platforms — HitPay, Stripe, and Airwallex — on the criteria that matter most to Singapore SMBs: invoicing features, local payment method support, fees, and payout speed.

What Should a Singapore Invoicing Platform Actually Do?

A basic invoicing tool generates a document. A payment-ready invoicing platform does more:

• Embeds a payment link that accepts PayNow, cards, and wallets

• Settles funds directly to a Singapore bank account

• Supports partial payments or deposit collection

• Sends automated payment reminders

• Reconciles payments against invoices automatically

For B2B invoicing specifically — common among creative agencies, logistics operators, and professional services firms — the ability to collect via PayNow or bank transfer without manual follow-up is the primary time-saver. As covered in the invoice payment guide for Singapore SMEs, embedding a payment link in every invoice reduces average collection time significantly.

How Does HitPay Handle Invoicing for Singapore Businesses?

HitPay’s invoicing feature is built into its core payment platform. Merchants create and send invoices directly from the HitPay dashboard, and each invoice carries an embedded payment link. Clients can pay via PayNow, GrabPay, ShopeePay, Visa, Mastercard, Amex, Atome, ShopBack PayLater, Apple Pay, or Google Pay — whichever method they prefer.

For businesses dealing with international clients, HitPay also accepts cross-border wallet payments including WeChatPay (China), UPI (India), PromptPay (Thailand), DuitNow (Malaysia), and QRIS (Indonesia) — all settled into a Singapore SGD account.

Settlement is next business day for domestic SGD transactions. Cross-border payments settle at T+2. There are no monthly fees or setup fees — merchants pay per transaction only. See hitpayapp.com/pricing for current card rates.

HitPay also allows merchants to customise payment receipts and invoices with branding, itemised line items, and tax fields — relevant for GST-registered businesses.

HitPay is MAS-licensed (PS20200643) and PCI DSS compliant. Approval takes 1–3 business days with no setup fee.

How Do Stripe and Airwallex Compare on Invoicing?

Does Stripe support invoicing in Singapore?

Stripe offers invoicing through Stripe Billing, which supports PayNow, GrabPay, cards, Apple Pay, and Google Pay in Singapore. It is a strong option for developer-led teams that want to customise invoice flows via API. Stripe has no monthly fee and operates on a per-transaction model.

The tradeoff: Stripe’s invoicing configuration requires developer time for custom setups. Out-of-the-box invoice customisation for non-technical merchants is more limited than HitPay’s dashboard-native approach.

Does Airwallex support invoicing in Singapore?

Airwallex offers payment links and bill pay features but its core strength is multi-currency treasury, expense management, and corporate cards. Its Explore plan is free; paid tiers start at SGD 79/month. For Singapore SMBs whose primary need is domestic invoice collection with PayNow, the subscription cost adds friction that per-transaction models avoid.

Airwallex is best suited to businesses that also need multi-currency accounts, international transfers, or expense management alongside invoicing — not for merchants primarily collecting SGD invoices locally.

Side-by-Side Comparison: Invoicing Platforms for Singapore SMBs

Which Invoicing Platform Is Right for Singapore SMBs?

For most Singapore SMBs — a Tiong Bahru fitness studio collecting class deposits, a Jurong East events firm invoicing corporate clients, or a freelance designer billing via WhatsApp — the decision comes down to three factors: local payment method coverage, fee structure, and how fast funds land in the bank.

HitPay covers the full Singapore payment stack with no monthly overhead. For businesses that primarily collect in SGD and want to offer clients PayNow, GrabPay, or BNPL on every invoice, it is the default-fit platform.

Stripe is a strong second for technically capable teams that want API control. Airwallex fits businesses that need invoicing as one feature within a broader treasury and spend management stack.

For B2B invoicing specifically — where clients may include regional offices paying via DuitNow or PromptPay — HitPay’s cross-border wallet acceptance handles those scenarios without requiring a separate integration. The B2B multi-currency payments guide for Singapore covers this use case in depth.
