Keep the billing conversation where it belongs — on the invoice.

"Did anyone talk to the partner about this invoice?" If the answer lives in someone's inbox — or worse, in a Slack message from three weeks ago — you have a process problem. Billing conversations scattered across email threads are billing conversations that get lost.

ModernPM puts threaded comments directly on every invoice. The conversation stays attached to the record.

How It Works

Partners flag questions. Billers respond. Everyone with access to the invoice can see the full thread. Comments create a permanent, timestamped audit trail that lives on the invoice — not in someone's email archive.

For firms with multiple billers and reviewers, this is the difference between a clean billing workflow and a scramble every cycle. Nobody's emailing "did this get addressed?" because the answer is right there on the invoice.

Why the Audit Trail Matters

Six months from now, a client calls to dispute a charge. In most firms, figuring out why that charge is on the invoice means tracking down the partner who approved it and hoping they remember the context. In ModernPM, the entire conversation is on the invoice — who flagged it, what was said, what was decided, when it was approved.

That's not just convenient. It's defensible.

The Bottom Line

Billing conversations belong on the invoice, not in email. ModernPM keeps them there — permanently, and accessible to everyone who needs to see them.
