Off-the-shelf agency tools charge $100-$400/month per seat and force you into their workflow. For a 10-person agency, that's $12K-$48K/year for software you'll never own. StackFast builds it custom, from $5K, once.
Give every client a login with your branding. They see project status, deliverables, timelines, and invoices — without emailing you. White-labelled. Professional.
One marketing agency reduced "where are we at?" client emails by 70%.
Pull data from Google Analytics, ad platforms, CRMs, and your internal tools into one client-facing dashboard. Auto-refresh. No more Friday afternoon report-building.
Saved 8 hours/week previously spent manually building client reports.
See every project, every team member, every deadline. Capacity planning, utilisation tracking, and workflow automation built around how YOUR agency works — not a generic template.
An agency owner finally had visibility into team utilisation without asking in standups.
Automate the messy first 2 weeks of a new client. Document collection, access setup, kickoff scheduling, brief templates. Consistent. Repeatable. Professional.
Client onboarding went from 2 weeks of scattered emails to a 3-day automated workflow.
