SaaS Development for Australia

SaaS Development, built around how Australia works

Australian SaaS founders often start with a local niche, such as trades, construction, allied health or agriculture, then expand to New Zealand, the UK or the US. That path shapes the architecture: Australian hosting at launch, with multi-region support designed in so a later move does not mean a rebuild. Nexzem builds SaaS products for Australian founders from India, from MVP to enterprise features.

Integrations are central to selling SaaS to Australian small businesses, many of which run their books in Xero or MYOB. Listing in the Xero App Store means meeting Xero's partner certification requirements, and a well-built integration can become a sales channel in its own right. For first releases, see our MVP development approach.

Billing, GST and the accounting ecosystem

We build subscription billing on Stripe Billing or Chargebee with GST-inclusive or exclusive display depending on whether you sell to consumers or businesses, tax invoices with the details the ATO requires, and PayTo or direct debit for customers who avoid cards.

For Xero App Store or MYOB marketplace listings, we build OAuth 2.0 connections, handle token refresh and rate limits, and map your data to their accounting model. We also prepare the security and data-handling answers their partner reviews ask for, while the partnership application itself stays with you.

Security and data expectations of Australian buyers

Enterprise and government customers in Australia ask detailed questions about data location, subcontractors and access from overseas. We document exactly how our team in India reaches your environments, which is part of answering those questionnaires honestly. The items buyers check most:

  • Hosting in AWS Sydney or Melbourne, Azure Australia East or Google Cloud Sydney
  • Application controls aligned with the Essential Eight, such as MFA and patching
  • Tenant isolation and per-tenant data export for APP access requests
  • Audit logs and alerts that support NDB assessments
  • Evidence for ISO 27001 and SOC 2 questionnaires from larger customers
  • IRAP-assessed cloud services when you target government agencies

SaaS Development overviewWhere else we work

SaaS Development in Australia, answered

Something else on your mind? Ask a consultant and get a reply within one business day.

Can we serve New Zealand customers from Australian hosting?

Usually, yes. Many New Zealand businesses accept Australian hosting, though New Zealand's Privacy Act 2020 has its own rules on sending personal information overseas, and some public sector buyers have stricter expectations. We design tenancy so a New Zealand region could be added later if a customer requires it.

Can you help us through an IRAP assessment?

An IRAP assessment is carried out on your system by an ASD-endorsed assessor, and the outcome belongs to your company. We build the controls, write the technical documentation and answer assessor questions about architecture, so the engineering side of the assessment is ready when you engage one.

How do you handle GST for overseas customers?

Billing logic can apply GST to Australian customers and treat overseas customers differently, since many exports of services are GST-free. The exact rules depend on who the customer is and where they are, so your accountant should confirm the treatment and we configure the billing system to match.
