Free Share Register Software: Keep Your Register of Members Online

Almost every company is legally required to keep a register of its shareholders — a register of members in the UK and Ireland, a stock ledger in the US, the libro registro de socios in Spain. It's the document a buyer, a notary or a tax inspector asks for, and it's often the one kept worst: a Word file updated once a year, if that. Aportia keeps it automatically from your cap table, and for now it costs nothing.

A Register That Writes Itself

Every time you record a transaction in Aportia — an issuance, a transfer, a split, a capital reduction — the register gets the corresponding entry with its date, the parties, the number and class of shares and the price. You never maintain the register separately, so it can't fall out of step with the cap table.

  • Chronological entries for every issuance and transfer
  • Holder details, share class, numbering and consideration
  • Current holdings per shareholder, derived from the entries
  • Export to PDF for a notary, auditor or buyer
  • Share certificates generated from the same data

Adapted to Your Jurisdiction

What a register has to contain depends on where the company is incorporated and its legal form. Aportia adjusts the terminology and the legal notes for Spain, the US, the UK, Germany, France, Italy, Portugal, Ireland, Mexico, Chile and Colombia — shares or participaciones, par value or not — and has a generic profile for other countries. It's a record-keeping tool, not legal advice, so confirm requirements with your adviser.

Transfers Without the Paper Chase

Recording a transfer between shareholders updates both holdings, writes the register entry and logs who recorded it. If the transfer is wrong, it is reversed with a new entry rather than deleted, which is exactly how a register is supposed to behave: corrections are visible, not hidden.

Audit Trail Behind Every Entry

Alongside the register, the audit trail records every action taken in the project with a timestamp and the user who did it. Together they let you show not only the current register but how and when each line came to be — the question due diligence always ends up asking.

Optional: Dynamic Equity Before Formal Issuance

Teams that haven't formally issued shares yet can track provisional ownership with dynamic equity and freeze it when they incorporate or issue. From that point the register starts with the frozen allocation. Most companies skip this and start straight from their issued shares.
