Software Costs


This article builds a prospective operational expense budget that you can take into consideration when preparing for your project. To achieve this we'll break out the items that are essential and other's that are optional and explain why. Knowing your web development costs avoids any surprises for you and loss of experience for your end-users. In addressing this upfront we hope that you can begin the project with the right expectations and make informed decisions from the very beginning of your development journey.

1. Support

Whenever an application is live in production - where end users can access it - we recommend that there is a dedicated support process. WorkingMouse offers level 2 support. There are many different ways support can be provided. We keep this process as simple as possible and detail our approach below.

WorkingMouse provide an online service desk portal and support number for you to call during business hours should you encounter a technical issue. Each reported issue is logged as a 'ticket' and you can submit as many support tickets as you need. The support team will triage each issue for a time-box 2 hours without charge and if they can resolve it within that time, they will. If they can't, they will provide an estimate of how long it's likely to take to resolve. WorkingMouse also offer skilled resources to deliver small enhancements. These too are estimated within time-box and, once approved by you, executed on a time and materials basis at a fixed hourly rate.

The cost for the service desk support facility with WorkingMouse Support to be opened and the ticket triage process to be operational starts at $500 excl. GST per month. This includes a managed transition of project artefacts between the development team and the support team, ensuring there is no loss of project knowledge. There is the hourly rate to resolve a support issue after the time box that should also be considered in the overall cost. It's important to remember that the software ecosystem is constantly evolving and issues will arise that need to be addressed. This could be in the form of a new App Store rule or an update to a web-based technology stack. It is recommended that you budget 10-20% of the total applications development cost for this as an operational expense per annum.

Monthly Support Budget

  • Service Desk: $500 excl. GST (Essential)
  • Support Budget:10-20% of the total development cost divided by 12 (Optional)

2. Hosting

For users to access the software, it needs to be hosted somewhere on a server. Previously this was done via local storage facilities, however these days it is easier and more reliable to use cloud-based storage. The two largest and most popular service providers for this are Amazon Web Services (AWS) or Microsoft Azure. You can host the application wherever you like as you own the code, however, if you would like WorkingMouse to do it for you, we can deploy it to our preferred cloud provider which is AWS. A resilient, load-balanced and scalable instance, including backups is usually between $400-$600 excl. GST per month.

Monthly Hosting Budget

  • Cloud Hosting: (AWS or Azure) $500 excl. GST (Essential)

3. Domain and SSL Certificates

A domain is what you purchase to access your website and email address. Eg. www.yourcompany.com. We can deploy the web application to a new subdomain of this eg. www.app.yourcompany.com. Domains vary in their price and usually cost about $10-$100 per year to manage and you likely already have one for your business. However, remember it should be branded to your applications purpose. On top of these, each deployed subdomain requires an SSL certificate. This keeps the domain secure and the data encrypted. This is usually $50 per annum per domain.

Monthly Domain and Certificate Budget

  • Domain Hosting: $9 Aud Excl. GST (Essential)
  • SSL Certificates $4 Aud Excl. GST (Essential)

4. Email

Usually included with your domain, email servers are important for sending a communication to your customers. An email server is usually ~$10 for business per month and likely included with your domain hosting. When the application is developed, the team will link up your email servers to send emails from the application. The reply-to mail address should be monitored by your customer service team.

Monthly Mail Server Budget

  • Mail Server $10 excl. GST (Essential but likely included in domain hosting cost)

5. Application Programming Interfaces (API's)

These are useful services that add significant value to the application and are integrated into it. There are a lot of third party API's that can provide significant value to your application without the cost of building the functionality yourself. For example, you may decide to API with Xero to manage invoices or Twilio a SMS service to manage direct communications. API's are usually charged per request or as per the value of their service and scales as you need them to. The main cost is the time to integrate them into the application. Third-Party API's work through volume of scale. The cost of the service scales based upon its usage. We would expect a small application to cost no more than $100 AUD per month.

Monthly API Budget

  • API Budget 2 API's $100 Excl. GST (Optional)

6. Membership Fee's

If you are developing mobile apps there are two membership fees to deploy to the relevant App stores. The Google Play store registration is a once-off fee of $25 including GST. The Apple Developer program is an annual fee of USD $99 including GST.

Monthly Membership Budget

  • Google Play Store $2.5 Incl. GST (Optional)
  • Apple Developer Account $12.5 Incl. GST (Optional)

7. Technology Platforms

There are many software development platforms and technologies that can accelerate development time, improve quality and enhance your ability to manage an application. We use the Codebots Platform. Codebots enables our customers to access all of their application information directly from within their own secure space on the platform and makes development up to 8.3 times faster. This is ~$80 per user, per month. Codebots is our in house platform engineering tool that empowers cross-functional software teams with reusable tools and capabilities through model driven engineering and DevOps. When developing with WorkingMouse there is no cost for using the Codebots platform whilst engaging our services.

Monthly Technology Platform Budget

  • Codebots Single Application ~$80 per user, per month AUD (Optional) - Included within Service Engagement

All in all, there's a lot to consider. Some of these costs are essential such as domains, emails and SSL's. However, what is optional can be excluded until it's necessary. Use the table above as a guide for your budget. Do not fear though, our role is to guide you through the journey of software development. We will recommend what to sign up for and when. Remember, the cost of developing your bespoke solution and owning the IP is always higher upfront than a licensed solution. However the total lifetime benefit of the software should prove considerably more valuable than the initial costs. As always, if you have any questions or would like to discuss please contact us here.
