Stripe Invoice

const invoice = await stripe.invoices.create({

3. Timely Sending: Send invoices immediately upon delivery
4. Automated Reminders: Set up reminder sequences for overdue invoices
5. Regular Reconciliation: Match payments to invoices weekly
6. Backup Records: Maintain copies in multiple systems
