More small-business apps to consider

The top small-business apps listed are the best overall in their category, but that doesn’t mean they’re the perfect fit for every business. If you’re looking for more industry-specific alternatives or have particular must-have features in mind, you might weigh these options, too.
Keep in mind that some apps — like QuickBooks Online and FreshBooks — can serve multiple functions. Be sure to check the feature list of your existing software to avoid adding a potentially redundant subscription to your expenses.

How to choose the best small-business apps

Here’s a rundown of each type of business app’s key function and which factors to consider to find the best fit.

POS apps

The best POS systems reach far beyond simply handling customer payments. Some systems are designed for specific industries, such as retail, online stores and restaurants. In addition to the cost of hardware and software fees, a processing fee for each customer transaction will typically be assessed. When comparing systems, pay attention to the following:
  • Hardware options, including card readers, terminals, cash drawers and receipt printers.
  • Inventory tracking features.
  • Monthly software fees and payment processing fees.
  • Card payment methods accepted (e.g., swiped, tapped or keyed).
  • Offline and mobile payment processing options.
  • Live support availability.

Accounting apps

Accounting software, at a minimum, tracks your business’s income and expenditures. The best accounting software has additional features that can make it easier to determine the financial health of your business. Look for the following features:
  • Ease of use.
  • Robust accounting reports.
  • Invoicing capabilities.
  • Integrations with third-party apps including payroll and POS systems.
  • Daily customer support.
  • Scalability.

Payroll apps

The best payroll software does more than help you pay your employees on time. Transparent pricing is a timesaver when comparing products and you’ll want to look for the following features:
  • Unlimited payroll runs.
  • The ability to calculate, file and pay federal, state and local payroll taxes.
  • Employee portal or mobile app. 
  • Benefits administration.
  • Next-day or same-day direct deposit options.
  • Accounting software integrations.

Invoicing apps

The best invoicing software helps you bill clients for your services, create quotes, track time and communicate with your customers. Before comparing products, consider the following:
  • Monthly software fee. 
  • Processing fees. 
  • Invoice customization options. 
  • Accounting software integrations. 

Expense tracking apps

The best expense trackers give you insight into where your business’s money is going and how efficiently it’s being spent. Above all, these apps should make it easy to record money out transactions, whether you’re at your desk or on the go. Here are some other points to take into account:
  • Mileage tracking. 
  • Employee app for submitting business-related expenses. 
  • Ability to snap photos of receipts with a mobile app. 
  • Accounting software integrations.
