Getting Started
Set up your first Interbooks business in under five minutes.
This guide takes you from sign-up to your first invoice in five minutes.
1. Create your account
Head to app.interbooks.sg/signup and enter your name, email, and a password. You don't need a credit card — every plan includes a 30-day free trial.
2. Add your first business
After signing in, you'll be prompted to create a business entity. You'll need:
- Business name (as registered with ACRA)
- UEN
- Financial year start date
- Base currency (defaults to SGD)
- GST registration status
You can add more businesses later from Settings → Businesses.
3. Choose your chart of accounts
Interbooks ships with a Singapore-standard chart of accounts (SFRS). For most SMEs the default is enough — you can customise it later if your industry needs additional account groups.
4. Connect your bank
Under Banking → Accounts, add your bank account details and upload your first statement (CSV or OFX format). Interbooks will start matching transactions immediately.
5. Send your first invoice
Click Invoices → New invoice, fill in the customer details, add line items, and hit Send. The invoice is emailed as a PDF and tracked automatically.
