Built in WA by a support worker who invoices plan managers too.
Sunday night, still doing invoices
Pick the client, pick your usual support, done. With the app already open, a repeat invoice takes about 10 to 12 seconds. A process that used to take an hour a week drops to a few minutes.
Rejected for a mistake you didn't even see
Wrong date range, wrong line item code, wrong ratio - the small stuff plan managers bounce back. Crestyn checks dates and codes automatically before you send, so you catch it, not them.
Did the plan manager even get it?
Every invoice shows Sent, Delivered or Bounced. If it bounces, you know that day, not at the end of the month.
What you get
- Rates always current
- Line items and caps come from the 2026-27 price guide, and the PAPL version in use is shown in the app.
- Your rates, per client
- Set a client-wide percentage or a per-code rate, then adjust any single line on the day if a shift runs different to usual.
- Amend without new-number chaos
- Made a mistake after sending? Amending voids the original and links to the replacement, so you never end up with two invoices carrying the same number.
- Paid and part-paid tracking
- Tick off lines as plan managers pay them, including the odd partial payments they actually make.
- Tax set-aside, worked out for you
- Mark an invoice paid and Crestyn shows what to put away from it for tax, super and bills like rego and insurance. It follows what you've actually invoiced, so the amount adjusts if you're busier than you expected. A guide for planning, not tax advice.
- GST threshold watch
- Not registered for GST? Crestyn tracks what you've invoiced and your projected income, and warns you early as you head towards the $75,000 threshold, so registering is a decision, not a scramble.
- Clean PDFs, your branding
- Your logo, your bank details, every required NDIS field, on a PDF you can download instantly.
- Email sent as you
- Invoices email from Crestyn with replies going to you, and a copy lands in your own inbox.
Straight answers on trust
- Built by a WA support worker who invoices plan managers too. About Crestyn.
- Independent of the NDIA and the NDIS Commission. Crestyn is a private tool, not a government service.
- Export everything, any time: invoices as PDF, records as CSV. Free whether you're on trial, subscribed, or read-only after your trial ends.
- Hosted in Australia (Sydney), encrypted at rest and in transit. Details on the security page.
Questions workers actually ask
- Do I need to be a registered NDIS provider?
- No. Crestyn is built for independent support workers invoicing plan-managed and self-managed participants, which does not require NDIS registration.
- What happens after the 30 day trial?
- You pay $14 a month to keep going, or you stop and the account goes read-only. Your invoices and client records export free for 90 days, and you can extend that in the app. An account that's never subscribed is permanently deleted 120 days after the trial ends, and we email you before it happens.
- Do you take a cut of my invoices?
- No. There is no commission and no marketplace. Your clients stay yours and your rates stay yours; the only cost is the flat monthly fee.
- Can I keep my invoice numbering if I switch mid-year?
- Yes. Set your next invoice number once and Crestyn continues from there, so your numbering stays unbroken for your records and your plan managers.
- Will it change my rates?
- Never. Crestyn flags anything over the current NDIS cap before you send, but your agreed rates are yours and the app never edits them.
- How long does it take to set up?
- A client takes less than a minute to add. Add your normal shifts, then with the app already open, repeat invoices come from your favourites in about 10 to 12 seconds.
- Is it just for NDIS work?
- The app is built around NDIS invoicing: line items, caps and plan manager workflows. If most of your work is outside the NDIS, it is probably not the right fit yet.
- Does it help me work out what to put aside for tax?
- Yes. Answer a few questions once (other income, a study loan, super, your regular bills) and it shows what to put away from each payment you mark paid. It uses ATO tax brackets and your invoicing so far this financial year. It's for planning, not tax advice, so check the detail with your accountant. You can switch off any part you don't need.
- What about GST?
- Most NDIS supports are GST-free, and Crestyn invoices state that properly. There is no GST maths to get wrong on a standard support invoice.
