How to Choose the Best Invoicing Software for Small Businesses

There are lots of things to look at when choosing the best invoicing software.

The most important is to look at the features to see if they fit the small business requirements.

Cost can also play an important part; some free products usually have restrictions in features or how many invoices you issue in a period. Some providers also provide a discount for the first few months or speak to your accountant; they may have reduced subscriptions with a software partner.

One of the easiest ways to find the solution for your small business is to take out a free trial to see the software in action.

When you take out a trial, check which level they have put you on, some will do the trial on a top range package, that you do not need all the features. Other packages might start you on the lowest version, and you will not see all the features required. If it happens, contact support and ask if the can change it.

All our solutions are cloud-based and are available to access anywhere with internet access.

Best Invoicing Software Features

Along with standard invoicing, there might be other features that a small business needs to look at, including:


A business may require invoicing and estimates. An estimate is helpful for quotes, proposals or bids to send to a customer to confirm a price and work to complete. The estimate can later turn into an invoice with one easy click.

Expense Tracking

If you invoice for expenses and time or products, some products have it built-in. Any recorded expenses are available to allocate to a project and invoice it.

Expenses may include mileage, travel, overnight stays and other sundries.

Mobile App

Multi currencies

Do you need to invoice in more than one currency? There are a few options available, including Sage, QuickBooks and Xero.

Payment Processing

Payment Reminders

Issuing automatic payment reminders can save a lot of time in the process of credit control. It is essential to keep on top of credit control for cash flow.

Recurring Invoices

If the business is subscription-based, recurring invoices is essential. It is also helpful in invoicing regular services. Setting up recurring invoices is usually done within the invoice.

Invoice Templates

All offer standard templates which allow uploading of logos and colours. The options may also enable you to create a template for the business and even more than one template. An example of this is a business that has two divisions, both requiring different invoice layouts.

Time Tracking

If you charge by the hour, keeping track of time is essential. An option on some mobile apps is to track in real-time and allocate to a project.

Top Tips for Invoicing

When you create invoices for a client, it is essential to include as much detail as possible. Here are our top tips on billing and invoicing:

  1. Unique invoice number – each invoice must have a unique number, it is best not to start with 1.
  2. Brand your invoice – Add a logo and brand colour where possible.
  3. Business details – Add all your business details, including address, telephone, email and website.
  4. Customer details – Ensure the customer details are correct, adding contact name if possible.
  5. Purchase Order Number – If one is supplied, ensure it is added to the invoice.
  6. Goods and Services – Include a full description, quantity and price.
  7. Payment details – Make sure it is clear where payment is made. It might be a payment gateway, bank details or who to make a cheque out to.
  8. Payments terms – If the invoice is due immediately, 7, 14, 30 days or net monthly.
  9. Payment due date – Make sure the due date is clear.

All of the above tips will make it easier to get the invoice correct and reduce the client’s risk of refusing to pay.
