What our customers say
Trusted by Australian Small Businesses
“I have been using Billability for a couple of months, and it has made a real difference to our invoicing process. Our business supports over 600 NDIS participants, so managing invoices accurately and efficiently has always been a significant challenge. Before discovering Billability, we explored Xero and several other international platforms. What immediately stood out about Billability was how straightforward it was to use. Setting up our invoice template, logo, business details and NDIS-specific information took less than 10 minutes-without complicated designing or customisation. Uploading and managing invoices is equally simple. Everything is clearly displayed in one place, including invoice details and due dates, making it easy to understand the status of our accounts at a glance. One of Billability’s greatest strengths is that it is designed specifically for NDIS providers. The platform makes it easy to select the correct support item and automatically populates the applicable NDIS price limit. This helps us stay aligned with current NDIS pricing, reduces errors and lowers the risk of invoices being declined. The customer service has also been exceptional. The team is approachable, responsive and genuinely listens to feedback. Features such as invoice remarks demonstrate that they pay attention to what providers need and continually improve the platform. Billability has made it much easier for us to manage and follow up outstanding invoices with participants and plan managers. It has made the entire invoicing process more seamless, accurate and efficient. I highly recommend Billability to any NDIS provider looking for a simple, reliable and purpose-built invoicing platform.”
