What are sub-wallets? Why do your customers need one?

With digital wallets becoming the norm of online payments, it has changed how your customers handle money. And your customers want more control, more clarity, and more flexibility in how they manage their finances.

They don’t want a single bucket of funds anymore. They want structure inside their wallet. Plus, they want clarity without complexity. And that is exactly where sub wallets step in.

According to Juniper Research, over 5 billion people are expected to use digital wallets by 2026. With that kind of scale, you cannot afford a “one-size-fits-all” wallet.

Your customers expect wallets that help them budget, plan, save, track, and stay in control without downloading five different apps. A sub wallet gives them that.

It allows them to create smaller, purpose-driven sections inside their main wallet. Each section can have its own rules, limits, and goals. For you as a bank, fintech, or financial institution, this brings better user engagement, higher retention, and stronger product value.

Let’s get started!

What Are Sub-Wallets?

A sub-wallet is a smaller wallet created inside the main wallet. You can think of it as a dedicated pocket inside a larger wallet. Each pocket has its own balance, purpose, and controls.

With it:

• Your customers get more structure.
• Your platform gets more activity.

And when you offer sub wallets, users can save for goals, assign spending limits, manage categories, hold different currencies, store rewards, and control how funds flow inside your ecosystem.

In simple terms:

Sub wallet meaning → A dedicated wallet inside the main wallet, created for a specific purpose.

Some people even search for SubWallet app, thinking it is a separate tool. But this feature lives inside a digital wallet or eWallet system.

And if you're a bank or fintech, offering a single wallet with multiple sub-wallets gives your customers a level of financial clarity they rarely get today.

How Sub-Wallets Work

Sub-wallets work on a simple idea. You give users one main wallet and then allow them to create smaller “money buckets” inside it for different purposes.

Each bucket holds real value. Each bucket carries its own rules. And each bucket helps the user keep funds organised without opening multiple accounts.

At a system level, the flow stays clean. The main wallet remains the parent account. The sub-wallets sit under it as controlled containers.

The user can move money between them instantly. Every transfer is tracked. Every event is logged. And every wallet follows its own spend limits and permissions.

Here’s how sub wallets works in your eWallet platform:

• The user creates a sub-wallet for travel, bills, savings, or family use.
• The platform assigns a unique ID to that sub-wallet for tracking and compliance.
• The user moves funds from the main wallet into the sub-wallet.
• Rules apply automatically: limits, merchant restrictions, or auto-top-ups.
• Transactions route from the sub-wallet, not the main one, so accounting stays accurate.
• You get real-time visibility into balances, spending, and usage patterns.

This structure gives your platform predictable fund flow, clearer compliance control, and a far better user experience.

Types of Sub-wallets

Before you offer sub-wallets to your customers, it helps to understand the different ways they can be structured. Each type solves a specific financial need, and together, they open up a wide range of digital wallet use-cases.

Below is a clear breakdown of types of sub wallets to help you see which model fits your product vision.

Sub-Wallet Type	Purpose / Use-case	Key Features	Example Use Cases
Category Wallets	Budgeting by category	Limit-setting, auto-allocations	Travel, Shopping, Emergencies
Parent-Child Wallets	Family money management	Parental control, tasks	Pocket money, allowance
Multi-Currency Wallets	Holding/Spending in various currencies	Currency exchange, FX management	Travel, Cross-border business
Savings Wallets	Goal-based savings	Milestones, interest, auto top-up	Car, House, Emergency Fund
Billing Sub-Wallets	Recurring bills	Scheduled payments, auto-refill	Utility payments, Rent
Promotion / Gift Wallets	Reward credits	Merchant-locked, time-limited funds	Cashback, Gift cards
Internal Benefit Wallets	Employer or platform funded	Restricted spend, pre-defined merchants	Employee benefits, marketplace credits

Difference Between Wallet and Sub Wallet

A wallet is the user’s primary store of value. It holds the full balance, manages KYC, controls limits, and acts as the main account for all transactions.

A sub-wallet, on the other hand, is a smaller, purpose-specific section inside that main wallet. It carries its own balance and rules but cannot exist independently.

For example: the main wallet is like a “bank account” and each sub-wallet is a labelled envelope used for budgeting.

The wallet gives access, permissions, and compliance, while each sub-wallet gives structure, spending control, and clarity.

This difference helps users stay organised and helps you offer richer, more personalised financial experiences without adding operational complexity.

Key Features of Sub-Wallets (To Build Into Your Digital Wallet)

Sub-wallets work best when they’re simple to use and easy to manage. As a bank or fintech, you want features that improve user adoption, reduce friction, and create daily engagement.

Sub-wallets let you set transaction caps or daily limits. This protects users from overspending and helps families or teams control shared budgets. You can even block merchants or restrict certain categories.

Auto Top-Up & Rules

Users can schedule recurring transfers or percentage-based allocations. Auto top-ups encourage consistency, especially for savings or bill-based sub-wallets. This increases retention because users rely on your app to stay organised.

Multi-Currency Support

With multi-currency sub-wallets, travellers, freelancers, or expats can hold funds in different currencies. This reduces FX fees, supports cross-border payments, and unlocks high-value use cases for your institution.

Independent Transaction History

Each sub-wallet stores its own history. Users instantly understand where the money went without filtering through the entire wallet. This clarity builds trust and reduces dependency on customer support.
