Frequently Asked Questions

How can I avoid waiting 30 or 60 days to get paid for a security audit?

Digital invoicing allows you to bypass the traditional mail-and-check cycle; by sending an invoice with an integrated 'Pay Now' button, you enable clients to settle the balance via ACH or Credit Card the moment the report is delivered.

What is the best way to handle a large project with a high upfront workload?

Use a digital invoice to request a non-refundable 50% deposit before any work begins. Automated systems ensure the project doesn't move to your active calendar until the payment is confirmed.

How do I deal with clients who claim they 'never received' the bill?

Switching to a digital invoicing platform provides tracking transparency, showing you exactly when the client opened the invoice, which eliminates excuses and provides a clear audit trail for follow-ups.
