Register of Registrable Controllers Software (Singapore)
Controllers identified from live ownership and control data across every layer of the group, so the ACRA register stays accurate as structures change.
EntityFlo maintains the ACRA register of registrable controllers for Singapore companies. Controllers are derived from live ownership and control data across the group, recalculated when structures change, and evidenced for audit.
What breaks once you pass five entities.
Controllers are calculated, not typed in
Significant interest and significant control run through holding companies and trusts, so a spreadsheet of names goes stale on the first restructure.
The register must be kept, not produced on request
Every Singapore company must maintain the register from incorporation and record changes within two business days of being notified.
One structure change breaks several registers
A single share transfer at the top of the group can shift controllers in every entity beneath it.
Built for complex Singapore holding structures
For groups where a Singapore entity sits under foreign parents, trusts or fund structures and controllers are not obvious from the share register alone.
Look-through across every layer
Ownership chains are traced through holding companies, trusts and foreign parents to the natural persons behind them.
Control as well as interest
Voting rights, board appointment rights and other control levers are captured, not just percentage shareholdings.
Changes surfaced immediately
A share transfer or officer change flags every controller register it affects, so the two-business-day window is met.
Audit-ready evidence
Every controller determination keeps its calculation trail and source data for inspection.

What controller compliance actually covers
The register is only defensible if the underlying ownership and control data is correct and current.

Because We’ve Done the Work Ourselves.
EntityFlo was built by people who understand the complexity, risk and manual work behind managing corporate groups.
"We went from spreadsheets and email chains to having every entity, every officer, and every deadline in one place. The compliance AI alone has saved us from three potential ASIC penalties."
"EntityFlo's structure charts finally gave our board the visibility they needed. Every ownership chain mapped, every UBO calculated. The lenders were impressed."
"Managing 40+ trusts and companies across three generations was chaos. EntityFlo made it simple. The compliance alerts alone are worth the price."
One flat monthly rate. Scales with your group.
No per-document fees. No per-filing fees. No paywalled AI tier.
The questions buyers actually ask.
Who is a registrable controller?
An individual or legal entity with significant interest in, or significant control over, the company: commonly more than 25% of shares or voting rights, or the ability to control the board.
How quickly must changes be recorded?
Within two business days of the company being notified of the change.
Does the register need to be filed with ACRA?
Controller information is lodged with ACRA's central register, and the company must also maintain its own register at all times.
Does EntityFlo handle trusts in the chain?
Yes. Trustees, appointors and beneficiaries are modelled so control through trust structures is traced to natural persons.
Can it cover UK PSC and Canadian ISC obligations too?
Yes. The same ownership and control model drives Singapore controllers, UK PSC, Canadian ISC and Australian UBO records.
