Karbon's October Release: Less Friction Between “Yes” and “Paid”
Karbon's October 26 release goes after the friction between a client saying yes and your firm getting paid. Here's every change, one note per feature.
By Max Ducharme

The most important activity a firm can do is get paid. The work gets done, the invoice goes out, but there are roadblocks between your client’s account and yours. Karbon’s October 26 release goes straight at that friction. They also took care of several small creature comforts that resolve some of my long-standing frustrations.
Each change has its own note: what it is, what it changes day to day, and what I’d do with it.
Billing and payments
- Clients can now pay by bank without logging in to their bank
- Apple Pay now works on Karbon payment links
Engagements
- Karbon now tells you when a signed engagement is waiting
- Engagements now have comments and @mentions
- You can now save a half-finished service template

The thread running through it
This release is about flow: from proposal to accepted engagement, from accepted to active, and from invoice to cash. Each feature removes a possible waiting step. Waiting is the hidden cost that’s nearly impossible to track, so I’m pleased to see Karbon working on removing the roadblocks that cause waiting.
If you want help turning any of this on, or finding your firm’s own “yes to paid” gap, drop me a note.
Brooks and I walked through the whole release on the October episode of the podcast.
