Can an accounting firm manage several clients in Invoice And Tax?

Yes. Accounting firms can manage several client organisations from one login and switch between them, while each client's data remains isolated. A dedicated partner programme is being shaped — tell us what you need.

For your team

Work the way a practice works

  • One login, many organisations

    A user can belong to several organisations and switch between them, including multi-branch clients.

  • Clear separation

    Each client organisation's data is isolated. Roles decide who can prepare, review or approve.

  • VAT figures with maker/checker

    Prepare and review your clients' VAT return figures with maker/checker approval: open, calculate, submit for approval, approve.

  • Bring data in any shape

    Import client data from Excel or CSV, enter it manually, or connect a client's system through the API.

  • Evidence for every adjustment

    Credit and debit notes carry reason codes and links to the original; audit events show who did what.

  • Exports for your working papers

    Most reports export to CSV and Excel, and documents are available as UBL XML.

Questions from firms

Does each client need its own subscription?

Commercial terms are agreed with our team; published prices are not yet available. Ask us about the arrangement that suits your practice.

Can a client see other clients' data?

No. Data is isolated per organisation, and your staff see only the organisations they have been given access to.

Do you file VAT returns for clients?

No. Invoice And Tax helps you prepare and review VAT return figures with maker/checker approval; filing remains with the taxpayer or their authorised agent through the Tax Authority's own channels.
