How to Improve Accounts Receivable Management in an NDIS Business

Managing an NDIS business involves more than delivering services and coordinating support workers. Providers also need to keep track of invoices, monitor incoming payments, resolve billing queries and maintain accurate financial records.

When these activities are not managed consistently, outstanding invoices can build up. Finance teams may spend valuable time chasing payments, investigating discrepancies and trying to understand which amounts are still pending.

For growing NDIS organisations, this can make cash-flow management more difficult. Even when a business is delivering services regularly, delays in invoicing and payment follow-ups can affect its ability to manage everyday operating expenses.

This is where effective accounts receivable management becomes important.

A well-organised process helps NDIS providers monitor what they are owed, identify payment issues earlier and maintain better visibility over their financial position. It also gives business owners and finance managers more reliable information when making operational decisions.

In this guide, we explain how Australian NDIS providers can improve accounts receivable management through better invoice processes, payment tracking, reconciliation and regular financial reviews.

What Is Accounts Receivable Management in an NDIS Business?

Accounts receivable refers to the money a business is owed for services it has already delivered but has not yet received payment for.

In an NDIS business, this may include invoices sent to self-managed participants, plan managers or payment requests submitted through the relevant NDIA systems.

Accounts receivable management involves tracking these amounts from the time an invoice or payment request is raised until the payment is received and correctly recorded.

For example, an NDIS provider may deliver supports during the week and issue invoices to the relevant funding contacts. Some payments may arrive within the expected timeframe, while others may remain outstanding because information is missing, a claim needs attention or the invoice has not reached the correct contact.

Without a consistent tracking process, it becomes difficult to distinguish between payments that are simply processing and those that require follow-up.

A structured receivables process helps providers:

• Keep track of invoices and payment requests.

• Identify overdue amounts.

• Follow up outstanding payments.

• Investigate discrepancies and rejected claims.

• Match incoming payments to the correct invoices.

• Maintain accurate financial records.

• Improve cash-flow visibility.

Accounts receivable is therefore not just an accounting activity. It is an important part of managing the financial operations of an NDIS organisation.

Common Accounts Receivable Challenges Faced by NDIS Providers

NDIS providers can experience different payment and invoicing challenges depending on their funding arrangements, internal processes and workload.

Some problems may appear small individually, but they can create a significant administrative burden when they happen repeatedly.

1. Delays in Sending Invoices

When invoices are not prepared and sent promptly after services are delivered, the payment process starts later than necessary.

This can happen when staff delay submitting service records, supporting information is incomplete or the finance team receives documents late.

For providers handling a high volume of services, even a short delay in invoice preparation can create a backlog.

2. Incorrect or Incomplete Invoice Details

Invoices containing incorrect participant information, support item details, dates or amounts may need to be corrected before payment can proceed.

The finance team may then need to contact the relevant staff member, update the invoice and send the corrected information.

These repeated corrections take time and can delay the collection process.

3. Different Payment Arrangements

NDIS providers may work with self-managed participants, plan-managed participants and NDIA-managed participants.

Each arrangement involves a different payment process. If the finance team does not understand where an invoice or payment request should be directed, it can lead to unnecessary delays.

4. Unclear Payment Status

A provider may have several invoices awaiting payment, but without an organised tracking system, staff may not know which ones have been submitted, approved, queried or paid.

This makes it harder to prioritise follow-ups and can result in the same invoice being checked multiple times.

5. Inconsistent Payment Follow-Ups

Some invoices may receive regular attention, while others are overlooked because there is no defined follow-up schedule.

Without clear responsibility for monitoring outstanding balances, payment queries can remain unresolved for longer than necessary.

6. Unmatched or Short Payments

Sometimes a payment received does not match the original invoice amount.

There may be multiple invoices included in one payment, a partial payment, an adjustment or an unresolved discrepancy.

If these transactions are not investigated and recorded correctly, the accounts receivable balance may become inaccurate.

Understand How NDIS Payment Arrangements Affect Receivables

Before improving accounts receivable management, providers need to understand how different NDIS funding arrangements affect the invoicing and payment process.

The person or organisation receiving the invoice depends on how the participant manages their NDIS funding.

Managing Invoices for Self-Managed Participants

For self-managed participants, providers generally send invoices directly to the participant or their nominated contact.

The provider should ensure the invoice clearly identifies the services delivered, the relevant dates and the amount payable.

It is also useful to maintain accurate contact details and confirm the preferred invoice delivery method.

If payment is outstanding, the provider can follow up through the agreed communication channel while maintaining professional and respectful communication.

Following Up Invoices Sent to Plan Managers

For plan-managed participants, invoices are generally sent to the plan manager for processing.

The provider should maintain accurate plan manager contact details and make sure invoices contain the information required for processing.

If an invoice remains unpaid, the provider may need to check whether it was received, whether further information is required or whether a discrepancy needs to be resolved.

Keeping a record of these communications helps prevent repeated follow-ups and gives the finance team a clear view of the invoice status.

Monitoring Payment Requests for NDIA-Managed Participants

For NDIA-managed participants, registered providers submit payment requests through the relevant NDIA provider payment system.

Providers should monitor submitted claims and check for any status changes, rejections or requests requiring attention.

The NDIA provides guidance on payment processing and claim requirements. Providers should follow the current requirements applicable to their services and payment arrangements rather than applying one follow-up process to every type of receivable.

Understanding these differences helps an NDIS business organise its accounts receivable workflow more effectively.

8 Practical Ways to Improve Accounts Receivable Management in an NDIS Business

Improving accounts receivable does not necessarily require a complicated new system. In many cases, the biggest improvements come from establishing consistent processes and making sure everyone understands their responsibilities.

1. Issue Invoices Promptly After Delivering Supports

The first step is to reduce the time between delivering a support and preparing the corresponding invoice or payment request.

When service records and billing information are submitted promptly, the finance team can process invoices without waiting for documents to arrive.

Providers can improve this process by:

• Setting a regular schedule for submitting service records.

• Defining who is responsible for preparing invoices.

• Checking that required supporting information is available.

• Avoiding unnecessary delays between service delivery and billing.

• Monitoring invoices that have not yet been issued.

For organisations with multiple support workers or service locations, a clear internal handover process can make a noticeable difference.

2. Check Invoice Details Before Sending

Incorrect invoice information can create additional work for both providers and the people processing payments.

Before sending an invoice, check that the relevant details are correct.

Depending on the payment arrangement and applicable requirements, this may include:

• Provider business name and ABN.

• Participant details.

• Invoice number and issue date.

• Description of the support delivered.

• Relevant support item number.

• Date and quantity of the support.

• Applicable amount and total.

• Required supporting documentation.

The details should match the actual service delivered and the applicable NDIS pricing and claiming requirements.

A simple invoice review checklist can help reduce avoidable errors and repeated corrections.

3. Maintain a Central Invoice Tracking System

One of the most useful improvements an NDIS provider can make is maintaining a central record of invoices and payment requests.

This does not have to be complicated. A suitable accounting system or well-managed tracking register can provide visibility over the receivables process.

Useful fields may include:

The tracking system should be updated whenever an invoice is issued, queried, corrected or paid.

This gives finance staff a reliable starting point when reviewing outstanding amounts.

4. Monitor Outstanding Payments Regularly

Waiting until the end of the month to review receivables can allow payment issues to go unnoticed.

A better approach is to review outstanding invoices regularly.

For example, an organisation may review its receivables several times each week, depending on its transaction volume.

During each review, the finance team can identify:

• Recently issued invoices awaiting payment.

• Invoices approaching their expected payment date.

• Outstanding invoices requiring follow-up.

• Rejected or queried payment requests.

• Transactions with incomplete information.

• Payments received but not yet allocated.

The aim is not to chase every invoice immediately. It is to understand what is happening and identify which items need attention.

5. Establish a Consistent Payment Follow-Up Process

Payment follow-ups should be handled through a clear process rather than relying on individual staff members to remember which invoices need attention.

Start by defining who is responsible for reviewing outstanding invoices and when follow-ups should take place.

For example, the process might involve:

Initial review: Check whether the invoice was sent to the correct recipient and whether the required information was included.

Status confirmation: If payment has not arrived within the expected timeframe, confirm whether the invoice was received and whether any further information is required.

Issue resolution: If a discrepancy is identified, gather the relevant records and arrange for the correction or clarification.

Further escalation: If the issue remains unresolved, refer it to the appropriate internal manager or follow the agreed escalation process.

Keep a record of every follow-up, including the date, contact person, response and next action.

This makes the process easier to manage and reduces the risk of duplicate communication.

6. Investigate Rejected, Disputed and Short-Paid Amounts

An outstanding invoice does not always mean that payment has simply been delayed.

Sometimes there is a genuine issue that needs to be investigated.

For example:

• The invoice may contain an incorrect support item.

• The service information may not match the supporting records.

• Required details may be missing.

• The amount may not match the applicable pricing requirements.

• A payment may have been made for only part of the invoiced amount.

When an issue occurs, avoid repeatedly sending the same invoice without understanding the reason.

Instead, record the problem, review the supporting information and identify what needs to be corrected.

For NDIA-managed payment requests, check the relevant claim status and current NDIA guidance. For plan-managed or self-managed arrangements, communicate with the relevant recipient to understand what is preventing payment.

This helps resolve the underlying problem rather than simply extending the follow-up cycle.

7. Reconcile Payments Against Invoices and Claims

Receiving money in the business bank account does not automatically mean that the corresponding receivable has been correctly cleared.

Payments need to be matched against the relevant invoices and recorded in the accounting system.

For example, a payment may cover several invoices, or one invoice may be paid in more than one transaction.

The finance team should check:

• Whether the payment amount matches the expected amount.

• Which invoices the payment relates to.

• Whether any balance remains outstanding.

• Whether the transaction has been recorded correctly.

• Whether any discrepancy requires further investigation.

Regular bank and accounts receivable reconciliation helps maintain accurate financial records.

It also prevents paid invoices from remaining incorrectly listed as outstanding.

8. Review Aged Receivables and Identify Recurring Issues

An aged receivables report helps providers understand how long invoices have remained unpaid.

Rather than looking only at the total outstanding balance, the report groups amounts according to how long they have been outstanding.

Common ageing categories include:

• Current.

• 1–30 days overdue.

• 31–60 days overdue.

• 61–90 days overdue.

• More than 90 days overdue.

The categories used should reflect the organisation's payment terms and reporting requirements.

A regular review can help identify whether overdue amounts are linked to a particular payment arrangement, recurring documentation problems or internal processing delays.

If the same issues keep appearing, the provider can investigate the underlying process instead of treating every overdue invoice as an isolated problem.

How to Use an Accounts Receivable Ageing Report

An accounts receivable ageing report is a useful financial tool for understanding the status of outstanding payments.

It shows how long invoices have remained unpaid and helps the finance team decide which balances require attention.

For example, consider an NDIS provider with the following outstanding receivables:

This example shows that the business has $16,000 in outstanding receivables. However, the total alone does not explain whether there is a payment problem.

The finance team should investigate the older balances first, check whether the invoices were received and identify any unresolved queries.

The report can also help management understand whether the outstanding balance is increasing over time.

For best results, review the ageing report regularly and use it alongside payment records, invoice tracking and bank reconciliation.

Key Accounts Receivable Metrics NDIS Providers Should Monitor

NDIS business owners and finance managers do not need to monitor dozens of financial indicators to understand their receivables position.

A small number of useful measures can provide a clearer picture of payment performance.

Total Outstanding Receivables

This shows the total value of invoices and other amounts still owed to the business.

It helps management understand how much revenue has been billed but not yet collected.

Overdue Invoice Value

This measures the amount that has passed its agreed or expected payment date.

Reviewing this figure over time can help identify whether collection delays are becoming more common.

Average Collection Time

This provides an indication of how long the business generally takes to collect payment after issuing invoices.

One commonly used measure is Days Sales Outstanding (DSO).

A simplified formula is:

DSO = (Average Accounts Receivable ÷ Credit Sales) × Number of Days

The calculation should use consistent accounting data and be interpreted in the context of the organisation's payment arrangements.

Unmatched and Short-Paid Transactions

Tracking unmatched payments and short-paid invoices helps identify reconciliation problems.

A growing number of unresolved transactions may indicate that the business needs a better payment allocation or follow-up process.

Percentage of Invoices Requiring Follow-Up

This measure helps management understand how often invoices need additional attention.

If a large proportion of invoices require repeated follow-ups, it may be worth reviewing invoice accuracy, communication procedures and payment tracking.

These metrics are most useful when reviewed consistently rather than as isolated monthly figures.

How Bookkeeping and Outsourced Administration Can Support Receivables Management

Maintaining accurate accounts receivable records requires regular attention. As an NDIS organisation grows, the volume of invoices, payments and follow-ups can become difficult for a small internal team to manage alongside other responsibilities.

Bookkeeping and administrative support can help maintain consistency across these activities.

Depending on the agreed service scope, an external team may assist with:

Invoice administration: Organising invoice information, preparing invoices and maintaining supporting records.

Receivables tracking: Updating invoice registers and monitoring outstanding balances.

Payment allocation: Recording incoming payments and identifying transactions that need further investigation.

Reconciliation support: Assisting with matching payments against invoices and maintaining accurate accounting records.

Ageing reports: Preparing regular reports showing outstanding and overdue amounts.

Administrative follow-ups: Tracking pending queries and coordinating routine communications according to the provider's procedures.

However, outsourcing does not remove the NDIS provider's responsibility for accurate claims, appropriate financial oversight and regulatory compliance.

The provider should establish clear approval processes and ensure that any external team has access only to the information and systems required for its assigned responsibilities.

For Australian organisations using offshore administrative support, privacy and data security arrangements should also be assessed carefully.

Building a More Reliable Accounts Receivable Process

Improving accounts receivable management is not a one-time exercise. It requires a process that can be followed consistently as the organisation grows.

Start by documenting how invoices are prepared, checked, issued, tracked and reconciled.

Assign responsibility for each stage so that tasks do not become dependent on one person's memory.

Set a regular schedule for reviewing outstanding balances and aged receivables. Make sure payment queries are recorded and escalated when they cannot be resolved through routine follow-ups.

It is also worth reviewing the process periodically. If invoices are repeatedly delayed because service records arrive late, the issue may need to be addressed with the operations team rather than the finance team alone.

The same applies when payments are frequently delayed because of incorrect details or incomplete documentation.

A reliable receivables process brings together service delivery records, billing administration, bookkeeping and financial oversight.

When these activities work together, providers have a better understanding of their outstanding payments and can make more informed decisions about their business operations.

Frequently Asked Questions About Accounts Receivable Management in an NDIS Business

1. What is accounts receivable management in an NDIS business?

Accounts receivable management is the process of tracking payments owed to an NDIS provider for services already delivered. It includes issuing invoices or payment requests, monitoring outstanding balances, following up payment queries and recording received payments.

2. How should NDIS providers follow up unpaid invoices?

Providers should first check that the invoice was sent to the correct recipient and contains the required information. They can then confirm whether it was received, ask whether further details are needed and record the outcome of each follow-up. The process should reflect the participant's funding arrangement.

3. How often should an NDIS provider review outstanding invoices?

The frequency depends on the provider's transaction volume. Organisations with regular billing activity may benefit from reviewing outstanding invoices several times each week, while smaller providers may use a weekly review. Aged receivables should also be reviewed as part of regular financial reporting.

4. What is an aged receivables report?

An aged receivables report groups outstanding invoices according to how long they have remained unpaid. It helps businesses identify older balances, prioritise follow-ups and understand whether payment delays are becoming a recurring issue.

5. How can NDIS providers reduce invoice payment delays?

Providers can reduce avoidable delays by issuing invoices promptly, checking invoice details before submission, using a central tracking system, following up outstanding amounts consistently and investigating discrepancies early.

6. Can accounts receivable management be outsourced?

Yes. NDIS providers can outsource suitable administrative and bookkeeping activities, such as invoice tracking, receivables reporting, payment allocation and reconciliation support. The provider should retain appropriate oversight and responsibility for the accuracy of its financial records and claims.

7. What is the difference between accounts receivable and payment reconciliation?

Accounts receivable management focuses on tracking money owed to the business. Payment reconciliation involves matching received payments against invoices, bank transactions and accounting records. Both activities work together to maintain accurate financial information.
