Frequently Asked Questions

How do I stop clients from ghosting me after I've delivered the final API code?

Digital invoicing allows you to set up 'milestone payments' where code is only pushed to the client's production environment after the digital invoice is marked as paid.

What is the fastest way to collect payment from international clients?

Using a digital invoice with built-in credit card and global payment processing ensures you aren't waiting 10 business days for a wire transfer to clear.

How do I handle clients who consistently pay late without feeling like a debt collector?

Digital invoices solve this through automated payment reminders; the system sends the 'nudge' emails for you, maintaining your professional relationship while prioritizing your cash flow.
