Invoice Inbox → Sheet
Parse billing emails, extract totals, log to a Sheet. Gmail filters included.
Watches the A1 ranges you configure and posts to a Slack incoming webhook when an edit lands inside one — saying what changed (cell, old → new, editor). Debounced so a flurry collapses into one message, and HMAC-signed so the receiver can verify it. Installable onEdit (fires for most API writes too).
Plain .gs files with comments and a README walkthrough. Runs inside your own Google account — no server, no third party. Single-buyer commercial-use license: use it in your own projects, business, and client work; you just can't resell or republish the pack's source.
Parse billing emails, extract totals, log to a Sheet. Gmail filters included.
Sync Google Calendar events to HubSpot as meetings. Idempotent writes.
Pull metrics from Sheets, render an HTML email, ship every Monday 9am.
