The small business guide to mobile invoicing

9 minutes

Gone are the days when small business owners would send invoices with envelopes and stamps. Today, mobile invoicing software can help you create invoices and accept payments faster and more efficiently than ever before.

Let’s take a closer look at how mobile invoicing works and how the right invoicing app can help you make more money while saving time.

What is mobile invoicing?

Invoices are formal documents that represent a request for payment, usually sent from a business owner to a client after the completion of a transaction. Mobile invoices are simply those that are sent via a phone or other mobile device.

This is accomplished using an invoicing app. The app typically complements the features of invoicing software you’re already using on your desktop or laptop. Data is synced across all platforms, which helps you manage invoices and keep your business running smoothly.

7 Benefits of mobile invoicing

Chances are that you’ve already come to rely on mobile apps for a variety of business processes, ranging from your calendar to project management software to accounting services. Mobile invoicing can help you further refine your business processes and provide the following benefits:

  1. Send invoices anytime, anywhere

Modern technology puts the power of your office in the palm of your hand. Mobile invoicing tools allow you to create and send an invoice on the go, which can be a great solution for small business owners who find themselves on the road a lot.

But mobile invoicing can also make you more flexible even when you’re at home. Nothing beats the convenience and flexibility of mobile invoicing.

  1. Get paid faster

The quicker you can send your bill, the quicker you can get paid. Most invoicing software tools allow you to automate your billing process, which can help you save time and streamline the entire process. Plus, many invoicing apps include automatic payment reminders, prompting your customers to pay their invoices on time and in full.

  1. Increase customer satisfaction

Your customers may value the simplicity and convenience that come from mobile invoicing, and the same features that save you time can save time for the customer as well. Additionally, most mobile invoicing software enables you to accept multiple forms of mobile payments. Customers may appreciate the flexible payment options you provide.

  1. Access your data anywhere

Online invoicing platforms allow you to have access to your company’s financial data in real time, so you always have a clear picture of your cash flow. You can access past invoices and look at future revenue right from your mobile device, helping you refine your strategy as your business expands and evolves.

  1. Mobile invoicing software enables growth

Mobile invoicing apps allow you to send more than just invoices. You can also use them to send estimates and request that your customers approve these estimates online before you begin your next job. This allows you to book more jobs and scale your business while keeping your core processes automated and easy to use.

  1. Standardized billing process

Mobile invoicing allows you to adopt a standard process when it comes to billing. This can help customers know what to expect when working with you, and it also makes it easy to train any employees who might work for your small business.

When you use a standard process, you’ll be better equipped to integrate your existing software into a seamless platform to conduct your financial and administrative tasks.

  1. Build your brand

The ability to send professional invoices can give your company an added layer of legitimacy. You can even customize your invoices to include your company’s logo and other details to set yourself apart. These features can increase the confidence your customers have in your business, which might encourage repeat business or help you to expand your client list.

Is mobile invoicing safe?

Online security is a major concern, especially now that businesses are increasingly relying on cloud-based solutions to store and manage their data. The same technology that offers convenience can also make you vulnerable to security breaches and cyberattacks.

We don’t want to minimize these threats. Instead, we want to highlight the fact that the risks are minimal while the rewards are substantial. Sending these documents faster makes your company more agile and more competitive, ensuring a strong, steady revenue stream.

Modern top software developers are constantly working to ensure safe, secure online transactions, and the digital platforms that you rely on for your industry are more than capable of protecting the information for both you and your customers.

How to create an invoice using a mobile app

Every invoicing app will be slightly different, but the overall process will look similar regardless of the platform you’re using. We’ll use Invoice2go’s product to explain how to create an invoice using your phone or tablet.

1. Create a new invoice

To get started, open the app and simply click the (+) symbol on your screen. Select “invoice” from the options, which will allow you to use the simple invoice template. Alternately you can customize your own invoices that include your logo and other unique information using our other tools.

2. Add client information

Next you’ll add client details, which should include such information as:

  • Company name
  • Point of contact
  • Company address
  • Phone number
  • Website
  • Email

These details can also be generated from your customer list, saving you time when you need to send multiple invoices to the same client.

3. Add details for the product/service

In the next step, you’ll add details about the product or service you’ve provided. Be as specific as possible.

Name the items, their individual prices, and the date they were purchased. You’ll use this data to calculate your subtotal. During this step, you can also add any discounts that may apply before continuing.

4. Add payment terms

Once you’ve calculated your total, you’ll include your payment terms. This includes accepted methods of payment, as well as any stipulations about deadlines or late fees.

Not every company will have deadlines or late fees, of course, but some business guides recommend assessing fees to ensure fast payments. Always make sure you discuss this with your customers beforehand so there’s no surprise when they receive your bill.

5. Review your invoice

Before you hit “send,” you’ll want to look over your finished document to ensure there are no errors. Common errors include mistakes in the company details or products that may have been accidentally omitted from the final tally.

6. Send your invoice

You’re done! You can now hit “send” to transmit the final invoice to your customer via text, email, or any other messaging service that you and your customer prefer to use. This includes popular social media messaging platforms such as WhatsApp and Facebook Messenger.

How do I bill for hours worked?

Some independent contractors will need to submit invoices for the time they spent working for customers. Invoice2go allows you to record your time through your phone or tablet. Simply follow these steps:

  • From the home screen, tap the “more” button in the right-hand corner
  • Next, select “time tracking”
  • Hit the (+) button and select from your list of clients
  • Hit the record button

This will allow you to track your time. Once your tracking is complete, you can convert this data into a finished invoice.

Try it free

Many business owners try to do too much too fast and burn themselves out attempting to handle bookkeeping, human resources, and accounts receivable all in one. But it’s incredibly challenging to juggle all these tasks without letting things slip.

Mobile apps can actually improve your performance while reducing the weight on your shoulders, and this can prove the greatest value of all.
