Mari Business Account: S$28 Instant Cash for SMEs and Sole Proprietors — The Complete 2026 Guide

Every MariBank referral post talks about the personal savings account and credit card. Almost none of them give the Mari Business Account the attention it deserves — even though it pays the highest referral reward of any MariBank product: S$28 cash, credited instantly, to both the referrer and the new business account holder.

​

If you run a sole proprietorship, partnership, or Pte Ltd in Singapore and have not looked at this account, here is the complete picture.

What the Mari Business Account Actually Offers

• 1.00% p.a. interest on your full business balance, credited daily — no tiers, no minimum balance
• S$0 monthly account fees and S$0 fall-below fees
• No minimum deposit required to open or maintain the account
• Free local transfers via PayNow and FAST
• Overseas transfers to 41+ countries in 20+ currencies, with a S$0 transfer fee promotion currently running
• Daily Seller Balance withdrawals for Shopee sellers — a genuine advantage if you run a Shopee storefront and want your seller proceeds moving into a working account without delay
• Fully digital onboarding — no document uploads, no branch visit

For context: a business current account at a traditional Singapore bank typically charges a monthly fee (S$15–S$38) unless you maintain a minimum average balance (often S$10,000–S$30,000). The Mari Business Account removes that calculation entirely. Whether your balance is S$200 or S$200,000, the fee is zero either way.

​

Who Can Open One

​

Eligible business structures:

• Sole proprietorships
• Partnerships (with no corporate partners)
• Private limited companies (with no corporate shareholders)
• Limited liability partnerships (with no corporate partners)

Eligibility conditions:

• The business must be registered in Singapore (ACRA-registered)
• All owners, directors, partners, and shareholders holding 25% or more of the business must be Singapore Citizens or Permanent Residents
• The principal applicant (the person opening the account) must hold a valid Singpass

If your business has any corporate shareholders or falls outside these structures — for example, a company with a foreign corporate parent — the Mari Business Account is not currently available to you. Traditional banks (DBS, OCBC, UOB) or business-focused fintechs (Aspire, Airwallex) remain the option for more complex corporate structures.

​

The Onboarding Process: Genuinely Paperless

This is where the Mari Business Account distinguishes itself from traditional business banking. Opening a business account at DBS, OCBC, or UOB typically requires preparing your ACRA BizFile extract, board resolutions, NRIC copies of all directors, and proof of address — often taking several days to weeks to process.

​

MariBank retrieves your business information automatically through Myinfo Business via Singpass. No scanning BizFile extracts. No uploading NRIC copies. No manual document verification queue. The entire process typically takes under 10 minutes if your Singpass is set up and your business is properly registered with ACRA.

​

Step-by-step:

1. Download the MariBank app (Apple App Store, Google Play, or Huawei AppGallery)
2. Register with a valid Singapore mobile number
3. Select Mari Business Account on the product page
4. Enter referral code 8ZUU96EA in the "Have a Referral / Promo Code?" field — before the Singpass step
5. Authenticate with Singpass — MariBank automatically retrieves your business details via Myinfo Business
6. Review and confirm your business details, agree to the T&Cs, and submit
7. On approval, S$28 cash is credited instantly to your Mari Business Account

What It Does Not Cover (Be Realistic About This)

Independent reviews are consistent on where the Mari Business Account falls short of a full-service business bank:

• No cheque book — if your business still needs to issue or receive cheques (some government agencies and older suppliers still require them), you will need a traditional account alongside MariBank
• No credit facilities on the account itself — MariBank offers a separate Mari Business Loan (both a standby credit line and a term loan up to S$500,000), but the business account by itself does not come with an overdraft
• No incoming payments from abroad on the account — limits its use for businesses that regularly receive international client payments directly into the account (outbound overseas transfers are supported; inbound international receiving is more limited)
• App-only — no branch, no relationship manager, no phone banking in the traditional sense
• Google Play reviews average around 4.4/5, with recurring complaints about login and face verification friction, and occasional account access issues

For a Singapore-based business primarily transacting in SGD, paying local suppliers, and managing day-to-day cash flow, these gaps rarely matter. For a business with significant cross-border receivables or a need for traditional credit facilities, MariBank works best as a secondary account alongside a full-service bank.

​

The S$28 Referral Reward: How It Compares

Here is the full referral reward structure across all MariBank products as at September 2026, so you can see exactly where the business account sits:

1. Mari Savings Account or Mari Invest Bundle → S$10 cash
2. Mari Credit Card Bundle or Instant Loan Bundle → S$15 cash
3. Mari Business Account → S$28 cash, the highest of any product

The reward is credited instantly to your Mari Business Account — no waiting period, no minimum transaction requirement. Both the referrer and the new account holder receive S$28.

​

This runs under a separate promotion cycle and separate cap from the personal banking referral programme, so business account referrals do not compete with the personal banking allocation for slots.

Why This Matters More Than It Looks

S$28 for opening an account you were likely going to need anyway is a straightforward win. But the more meaningful value is what the account itself removes from your business banking overhead: no monthly fees regardless of balance, 1% p.a. interest on cash that would otherwise sit idle in a zero-interest current account, and same-day access to Shopee seller proceeds if that applies to your business.

​

For a solopreneur, freelancer with a registered business entity, or small SME owner who has been putting off separating personal and business finances, the combination of zero cost, fast onboarding, and an instant S$28 makes September 2026 a reasonable time to make the switch.
