What do invoice apps do?

An invoicing app is software that helps you create, send and follow up on invoices.

Modern, cloud-based invoicing software also helps you save time and money by easing the billing process and automating formerly manual tasks. Furthermore, they can help you reduce the likelihood of mistakes by helping you fill out fields and notifying you when it detects that information is missing or wrong.

Here are key reasons to choose to invoice apps over invoicing templates:

  • Create invoices in a few clicks: Invoicing apps make the process of creating invoices easier by filling out a number of fields automatically and helping you send the invoice without any manual interaction.
  • Work on the go: As long as you have got an internet connection, you can always create invoices and retrieve reports on your business’s financial development.
  • Spend less time chasing payments: Billing apps can help you track past-due bills by automatically sending payment reminders.
  • Send several invoices at the same time: Many invoicing programs allow you to send invoices in bulk. This is a good feature for businesses that send the same invoice to several customers.
  • Automate invoicing: Use recurring billing functionality to send invoices per week, month, quarter or year on autopilot.

Some invoice apps also offer their own time-tracking apps and a library of this-party integrations to streamline invoicing even further. In sum, these features make invoicing apps a better and more efficient way of generating invoices than templates.

How to choose the best invoice app for your business

When selecting the ideal invoicing app for your company, we advise that you go by the following guidelines:

  • List your needs: Create a list of all your must-haves and disregard the software that does not meet those requirements.
  • Choose simple: Make your invoicing process as effortless as possible by choosing software which meets your needs – and no more than that. There is no point in overcomplicating things with complex software that has numerous features you never use.
  • Pay attention to price: Some invoicing software has cheap starter plans and charges you heavily when exceeding certain thresholds. Make an estimate for your invoicing volume per month and choose the software that meets your needs at the lowest cost.
