Your questions, answered
Before you invite your first client.
No. You prepare the returns in your own tax software, and you or your client file them as today.
Yes. The data pack exports from your advisor workspace, so your team can bring the figures into the tax software you already use to prepare the returns.
Nothing is shared until your client accepts your invite and chooses what you can see, from full access to periodic snapshots. Connections are read-only, and your client can revoke access at any time.
Pricing depends on how many clients you invite and which forms you prepare. Book a 15-minute call and we will walk you through the options for your practice.
Clients can connect bank, investment, pension, credit card and wallet accounts across 30+ countries, including the United States, the United Kingdom and Spain, through read-only connections.
