Seven Financial Tools You Need to Manage Your Small Business

From a business bank account to tax software, these are the essential tools you need to manage your business finances.

Whether you’ve decided to start a business in retirement or you’re making the leap to trade your day job to fulfill your passion, handling your small business’s finances can get complicated and messy fast if you don’t have the right tools. But which tools do you really need? How do you decide which ones to get?

To help you build a tech stack that works for your needs, look into adding these seven tech tools to manage your finances easily and accurately.

1. Business bank account

Not only is a business bank account required for most small businesses, it can often make your life as a business owner easier. With a tech-forward option like the Mercury business checking account, for example, you’ll get extra features like third-party integrations with your accounting software, payment processing service and other important business tools. It can even generate invoices, match incoming payments to those invoices and do dozens of other handy functions that streamline the financial side of your business.

Whichever business bank account you choose, make sure to check the fees, minimum balance and other requirements. While Mercury offers a no-fee, no-minimum option, many banks charge fees, especially for accounts with more advanced tools and features.

2. Accounting software

Almost as important as a business bank account, accounting software is integral for ensuring you’re accurately keeping track of your revenue and costs. This is also where you’ll be able to create and keep track of invoices, manage your bills and generate reports to analyze the financial health of your business.

With that said, there can be a lot of variation between programs, and between the tiered plans offered by each software. So it’s important to shop around and compare the features that come at each price point across a few different programs before you commit to any particular accounting software.

It also helps to have software that integrates with your business bank account. While not every bank offers this, Mercury business accounts integrate with QuickBooks and Xero, two of the leading accounting software options. This can automate a lot of the data syncing and reporting needed to keep your accounting up to date and accurate.

3. Payment processor

Whether you sell a physical product or offer a service, you need a way to process various types of payments like credit cards and mobile payments. There are plenty of different payment processing services out there, with Stripe and Square being two of the more well known brands.

But the fee structure and account requirements vary significantly, so it’s important to take a close look at each one and estimate how much you’ll pay each month based on the types of transactions you process the most.

With a Mercury bank account, you’d be able to link Stripe to your checking account to take advantage of Mercury’s invoice generation features and set up automatic transfers from your Stripe to your Mercury account. If you’re not sure where to start with choosing a payment processor, this is a convenient place to start.

4. Tax software

Getting your taxes right each year is as stressful as it is important. So working with a great tax prep software that caters to small businesses is key. Whether you want to hire a pro or file them yourselves, opt for tax prep software that at least offers the option to ask a live tax expert questions as you go.

Ideally, it should also integrate with your preferred accounting software, too. This just makes it easier to import your documents and lower the risk of errors as you fill out your tax return.

5. Payroll software

There’s more to paying your employees than cutting checks. With payroll software, you can easily calculate paychecks, withhold taxes and other deductions and keep up with evolving employment laws and compliance.

It also helps track time-off accruals and usage and provide an employee portal where your employees can easily check pay history, get pay stubs or change direct deposit information. Come tax time, payroll software can even help with generating W-2s to employees.

Overall, it’s an important way to cut down on the manual calculations and paperwork involved in paying employees. So if your business is made up of more than just you, this is a must.

If your team is still relatively small, though, look for software that’s scalable. That is, you want payroll software that offers a lower cost basic version so you’re not paying for robust tools that you don’t need yet or the ability to process payroll for hundreds of employees when you currently only have a couple of people on your staff.

6. Financial planning software

Financial planning software allows you to both track your past performance and plan for the future. It will include features like budgeting, forecasting and scenario planning that help you make data-driven decisions and set financial goals or projections for your business.

To start, you might want to keep costs down by opting for accounting software that includes at least a few basic financial planning features. But, as you grow, explore more advanced tools that offer things like automated identification of cost saving or growth opportunities.

7. Secure financial document storage

As a small business owner, you’ve got a growing pile of important documents to keep track of: Receipts, payroll records, permits and licenses, insurance and the list goes on. While you might not need to access all of these documents in your day-to-day, it’s important to store financial documents the right way so that you can easily find them when you do need them.

Both digital and physical storage options exist. But even with physical documents, it’s a good idea to save scanned copies in a secure digital location, just so you have a backup.

How to build the right tech stack for your small business

As mentioned earlier, integration is key. Having seven different financial tools that can’t talk to each other will force you to put in a lot of manual effort to keep the data synced across each one. So, whenever adding a new tool to your toolbelt, start by checking which third-party platforms your existing tools integrate with already.

But, even before looking at integrations, look for software that consolidates multiple tools into one. Even if you don’t need some of the more advanced features just yet, starting with an entry-level version of a software that offers optional add-ons or upgrades will make it much easier for your business to scale without having to overhaul your tech stack as you grow.

Say business is booming and manually generating invoices each month is getting tedious, compare the cost of buying new software to that of upgrading what you already have. For example, upgrading from Mercury’s free business account to Mercury Plus (which offers recurring invoice generation) costs just $35 per month.

That may be more cost-effective and easier than adding a brand new piece of software to your tech stack, especially when you factor in the other features that come with the upgraded business bank account.
