FAQ

Common questions

Do I need to know how to code? +
Not at all. Everything is pre-built. You only need a Google account and about 20 minutes to set up.
How does the PDF invoice look? +
Professional and clean — your logo, business name, client details, line items, and bank info. Saved automatically to your Google Drive.
Does the auto-reminder actually send emails? +
Yes. It uses your own Gmail account via Google Apps Script. The emails come from your address, not a third-party service.
Can I customise the invoice template? +
Yes. Business name, logo, payment terms, currency, and footer are all configurable in a settings sheet.
How many clients can I have? +
Unlimited. Add as many clients as you need to the client database — invoices pull their details automatically.
Is my data private? +
Completely. Everything lives in your own Google Drive. No CodeLeaf server sees your invoices or client data.
