Watch out for

Airtable API has strict rate limits, add exponential backoff logic to prevent throttling errors during bulk updates.
Floating point arithmetic can cause rounding issues in quantity calculations, use integer conversion or a rounding library to ensure whole units.
Duplicate checks might miss orders if the status field is null, so explicitly filter for both 'Pending' and empty status values.
Brevo email templates may break if special characters are not escaped, sanitize all product names before injecting them into the HTML body.
