Your clients on Zoho Books shouldn't be the ones you have to log in somewhere else to check. Connect their organisation to Sodium and their numbers sit in Client Books on their client record, the same way as your Xero and QuickBooks clients.
Most of your clients might be on Xero, but some will have chosen Zoho, often because they already run their business on Zoho One. That shouldn't make them the awkward ones. Once connected, a Zoho Books client looks like any other: the same Books tab, the same reports, next to their services, tasks and documents.
Profit and loss runs for any period you choose, with income, expenses and profit pulled out at the top and Zoho's own sections beneath them. The balance sheet shows the client's position as at any date, and says which date the figures were stated for.
Bank accounts come with their currencies and balances, and the chart of accounts is there when you need a nominal code without asking the client for it.
Sales opens on how much the client is owed and how old it is, by customer, with the invoices underneath. Purchases does the same for what they owe their suppliers. Each invoice and bill links straight through to the record in Zoho Books when you need the detail.
Sodium reads from Zoho Books each time you open a tab, so what you see is what is in the books right now. It only ever asks Zoho for permission to read, so it can't change anything in the client's accounts.
You connect through Zoho's own sign-in, wherever the account is hosted, UK included. Your team gets the financial context on a client without anyone handing round a Zoho login.
Zoho Books is for your clients' books. For your practice's own invoicing and importing your client list, Sodium connects to Xero, QuickBooks, FreeAgent or Sage.
