The preview shows a tax invoice with your company details, the customer's billing and shipping address, the item table, totals, and the amount in words. If you do not charge GST, toggle to **Bill of Supply**. ## Add your branding On the right, under **Customize Invoice**: | Setting | What it does | Scope | | ------------ | ------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------- | | Company Logo | Appears at the top of the invoice. | Saved against your company, applied to every invoice. | | Signature | Appears in the signature block. | Saved against your company, applied to every invoice. | | Bank Details | Tells the customer where to pay. | Saved against your company, applied to every invoice. | | Notes | A custom line on the invoice, for example "Credit period of 15 days". Found inside the Bank Details dropdown. | Invoice-specific, changeable each time. | ## Download Click the **Download** icon at the top right. You get a PDF you can email or print. Set the logo, signature, and bank details before your first customer invoice, so you are not editing and re-downloading later. Use the Notes field for payment terms that vary by customer, rather than the narration, which stays internal.
