What changes with your country.
A country pack switches the parts that differ. Rates and thresholds live in dated tables, so a Budget is a data update, not a new app.

Why the country is fixed
Chosen once, at sign-up.
Your country decides how every entry is recorded from the first one: the tax year it falls in, the category it maps to, the invoice wording, the payroll rules. Switching halfway would rewrite your history, so it stays put.
- One business, one country.Each account keeps the books for one business in one country.
- Moving country means a new business.Sign up again for the new country; your old books stay as they were.
- Both countries? Two sign-ups.A UK business and a Sri Lankan one are two separate accounts.
Data residency
Where your data lives: still to be confirmed.
We haven’t chosen the hosting region yet, and we won’t pretend otherwise. Here’s where the decision stands.
- United Kingdom
- A UK or EU region, under UK GDPR.
- Sri Lanka
- Being decided under the Personal Data Protection Act, whose core duties start on 1 January 2027.
We’ll publish the region here and in our privacy notice before launch.
No. Your country is fixed at sign-up because it decides how every entry is recorded. Moving country means signing up a new business.
Not yet. Each account keeps the books for one business in one country, so you’d sign up twice.
Yes. Quotes, invoices, bills and expenses can be in another currency, like US dollars or euros. Your books stay in your home currency: each one is converted at the day's rate (which you can change), and the difference when the money actually moves is kept as an exchange rate gain or loss.
No. In the UK your accountant files your MTD updates and VAT; in Sri Lanka you or your practitioner file with the IRD, and the year goes to TaxWise.lk. Filing links may come later.
English first. Sinhala and Tamil invoice templates and payslips are next.
Not for now. Adding a country means a new pack of rules and a local accountant channel, so we’re doing two well first.
