The bill nobody totals up.

Your stack isn’t expensive — it’s compounding. Six subscriptions, six logins, and the 22 hours a week spent being the human bridge between them.

Here’s what changes

Three things stop happening on Monday morning.

No. 01 · The pain

Senior consultant leaves. All client context walks out the door with them.

The fix

Every interaction lives on the firm's record.

Calls, proposals, project milestones, invoices — all attached to the client under the firm's account. When someone leaves, the relationship stays.

No. 02 · The pain

Every partner uses their own proposal template. In their own way.

The fix

One template library across the whole firm.

Junior partner pulls the retainer template, personalises scope, sends in 9 minutes — and it looks exactly like the senior partner's output. Consistent brand, every proposal.

No. 03 · The pain

Milestone complete. Invoice raised three weeks later.

The fix

Milestone done. Invoice sent that day.

Mark Phase 1 complete in the project. Open the client record, create the invoice from the milestone, send — no end-of-month panic, no client asking where the bill is.
