We got a lot of positive feedback on our recent post on “4 Time-Saving Apps for Your Small Business” so wanted to share with you some information on other apps for your consideration.

Today, we’re focusing on apps for finances. Although the unpredictable nature of running a small business can keep it exciting, one area where it’s best to avoid daily surprises is with your money. If you don’t stay on top of your finances, it’s possible to miss opportunities for growth because you lack the cash on hand—or fall behind on your bills. Here are four free or low-cost apps to help you stay organized.

Xero. It’s easy to make mistakes in your invoicing or accounting if you’re relying on a hodgepodge of Excel spreadsheets. This program—which handles everything from invoicing to payroll— is popular among entrepreneurs who are looking for a software that is easy to learn.

QuickBooks. For many small business owners and accountants, this is a tried-and-true favorite for tracking expenses, handling invoices, creating a profit and loss statement, and more. It has evolved in recent years to connect to PayPal, Square, and other digital financial services apps.

Expensify. If you travel a lot, it’s easy to lose some of the business receipts you accumulate—and miss out on tax deductions. This free app will help you record them, track business mileage, and generate expense reports quickly.

Small Business Workbench. Burning through too much cash can jeopardize your business. This app will help you forecast how much money you’ll have in the bank weeks ahead of time. That way, if you’re in danger of missing an important payment next month, you’ll know far enough in advance to come up with a smart plan.
