Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers

- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The directors have prepared a 5-year plan and cash flow forecasts to assess going concern. These indicate that even taking account of possible anticipated downsides and based on consideration of the Company's current performance against its forecasts, the Company will have sufficient capacity to meet its liabilities as they fall due during the going concern assessment period. The directors have also received a letter of financial support from simPRO Holdings (Aus) Pty Limited to confirm the provision of adequate financial resources to the Company for a period of not less than 12 months from the date of approval of the Company's statutory financial statements. Consequently, the directors are confident that the Company will continue to meet its liabilities as they fall due for at least 12 months from the date of approval of the financial statements ("the going concern period") and therefore have prepared the financial statements on a going concern basis. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “On 25 October 2024, Sonar TopCo, Inc. group ("The Sonar Group") acquired the Group through its wholly owned subsidiary, Simpro Corporate Pty Ltd., which now owns 100% of the issued share capital of BigChange TopCo Limited and its controlled entities, including BigChange Limited.”
- “All options were exercised on the sale of BigChange Topco Limited in October 2024.”
