One of the first steps founders take when launching a startup is setting up a dedicated business checking account.

But as the business grows, one account is often no longer enough.

In a world where 16% of startups fail because of financial problems, allocating income and expenses across multiple business checking accounts can give founders a birds-eye view of their startup’s financial situation, helping them make smarter decisions.

And thanks to online banking, organizing and managing a startup’s banking infrastructure is now easier than ever. Let’s explore how multiple business checking accounts can improve budgeting and how a founder might arrange their banking infrastructure for effective income and expense management.

What are the benefits of having multiple business checking accounts?

Maintaining multiple business checking accounts can support your business in a number of key ways:

  • Financial organization. Maintaining multiple accounts with specified purposes clarifies a business’s financial status. With a glance, founders can see if they have enough to cover the next payroll cycle or if they can afford that new piece of equipment. If the business is short in one expense category, it can simply move cash from one account to another. Having its finances in order can also make it easier for the business to determine how much runway it has and when it needs to raise a new round of financing.
  • Recordkeeping. Most startups create quarterly financial statements — but financial decisions happen a lot more frequently. A startup’s bank statements can provide detailed and timely insight into crucial income and expenses. Leveraging multiple checking accounts can help break those financials down further and give a clear look into category-specific cash flows.
  • Tax prep. Having multiple checking accounts makes tax prep easier because it allows the business to automatically set aside cash to cover its quarterly or annual tax bill.
  • Manage spend. For specific operating expenses, like software subscriptions and travel, having a designated checking account allows the business to create dedicated credit or debit cards, making it even easier to track these expenses.
  • Security. Dividing funds across multiple accounts can safeguard your money from fraudulent activity or a breach in security.

How does having multiple business checking accounts improve budgeting?

The goal when maintaining multiple business checking accounts is to be able to allocate income across various expense categories automatically. This way, when an expense comes due, the company can tap the account needed to cover the cost — no mental math, no tricky accounting.

But creating dedicated checking accounts requires an understanding of what a business’s major expense categories are. While every business is unique, common startup expense categories include:

  • Payroll
  • Operations
  • Taxes
  • Contractors / vendors

Based on the size of each expense, the founder can determine what portion of income should be allocated to each account (e.g., 30% of revenue to payroll, 15% of revenue to taxes, etc.).

This approach allows the business to use its bank as a built-in budgeting tool. If the business were to keep all income in one checking account, it’d be harder to tell if it had the cash to cover expenses.

What are some examples of business checking accounts for bucketing your startup’s cash?

Again, the amount of checking accounts a startup may need should depend on the business’s major budget categories. Founders should consider where their business spends the most money and if it would be helpful to hone in on specific expense categories. Here are some examples of startup checking account categories that may be useful for budgeting:

Primary checking account

A primary checking account can be used to collect all business revenues before allocating that cash flow into respective expense accounts. This account should receive all direct deposits, wires, and invoices.

OpEx

An OpEx (operational expense) account should cover recurring monthly expenses related to running your business, such as rent, software subscriptions, third-party vendors, advertising/marketing, and utilities. Depending on the scale of the business and its specific operational costs, it may make sense to break out OpEx even further. For instance, a company that spends a lot on travel each month may consider a dedicated travel checking account. Meanwhile, a business that owns multiple brick-and-mortar stores may want to create separate OpEx accounts for each store.

Payroll

As a startup grows its team, managing payroll becomes increasingly complicated. Organizing a dedicated account for payroll and funding it regularly ensures the business never falls short of its payroll obligations.

Taxes

As mentioned earlier, setting aside cash to cover taxes can provide peace of mind come tax season. It’s a good practice to set aside a portion of all accounts receivable equal to the business’s tax rate and transfer that directly into the tax account every time the company receives a new payment.

Emergency expenses

Startups need to expect the unexpected. An emergency fund will put the business on better footing if and when unforeseen circumstances interrupt cash flow or threaten a company’s ability to carry on with business as usual. A small recurring allocation can prove invaluable when extra funds are needed to run payroll, pay off a debt, or cover a business-critical service.

Accounts receivable

If a business has multiple large revenue streams, it can make sense to divvy up this income into different checking accounts rather than collect them all in one primary checking account. This approach can provide better insight into a business’s revenue generators. For instance, a company with multiple brick-and-mortar stores may want to collect the revenues for each locale in separate accounts — such as they might do with OpEx — to see how their performance compares.

Savings

Aside from these business checking accounts, a startup should also aim to set aside cash in a savings account for significant future expenses. The savings account should ideally be interest-bearing so that idle cash can go to work for the business.

How to allocate money into multiple business checking accounts

How much you choose to allocate to each business checking account will largely depends on the startup’s unique financial situation. Generally speaking, startups allocate a lion's share of their income to covering payroll and operations. When determining how to allocate income, it’s helpful to focus on the total revenue the startup brings in every month, and how that cash should be distributed across various accounts based on the business’s largest expenses.

Consider a startup that generates $15K per month in revenue, where payroll comprises about 50% of expenses, operations comprises about 25–30%, and taxes comprise around 20% (the average federal tax rate for small businesses). Here’s how such a startup might consider distributing income into its various business checking accounts:

Are multiple business checking accounts right for me?

Multiple business checking accounts can help growing businesses be more thoughtful about managing cash flow. However, it’s important not to complicate things too early. A small startup with limited revenue streams and expenses often only needs a single business checking account to manage money effectively.

In the early days of a business, it can also be distracting for the founders to manage the added obligations that come with maintaining multiple business checking accounts (e.g., maintaining minimum account balances, tracking transaction limits, etc.).

We recommend founders look into opening additional business checking accounts after seeing a large cash inflow, such as from a fundraising round.


Scaling your business means being smart about how you manage money. Setting up multiple business checking accounts to handle major cash inflows and outflows is a great way to ensure you’re working within your budget and positioning your business for long-term success.
