The Problem with Patchwork SaaS
Accounting firms juggle multiple subscriptions, each adding cost and complexity while scattering client data.
Calendly
Separate scheduling tool with its own subscription. Another login, another monthly bill, another silo of client data.
Typeform / Google Forms
Client intake forms disconnected from workflow. Data lives in a different system, requiring manual copy-paste.
DocuSign
E-signatures in yet another platform. Per-envelope fees add up fast during tax season.
Lightweight CRMs
Client data scattered across systems. No single source of truth for your accounting relationships.
QuickBooks / Xero Plugins
Integrations that break and require maintenance. Each plugin is another point of failure.
Data Chaos
Disrupted client journey and compliance risks. Each silo increases the chance of something falling through the cracks.
Each subscription adds cost. Each login wastes time. Each silo risks compliance.

What Accounting Firms Are Saying
“AltStack transformed how we manage client onboarding. What used to take our team 2 hours per client now takes 15 minutes. The AI agents handle the repetitive tasks while we focus on what matters — building relationships.”
“We consolidated 6 different software tools into one platform. The cost savings alone paid for the switch in the first month, and our team productivity has never been higher.”
Multi-office CPA Firm
“As a growing firm, scalability was crucial. AltStack's workflow automation let us triple our client base without adding headcount. It's like having an extra team member that never sleeps.”
Cloud-based Bookkeeping
“The client portal alone transformed our client experience. Fewer emails, faster document collection, and clients love the transparency.”
Tax Advisory
“CPA scheduling with automatic reminders cut our no-shows by 40%. We should have switched years ago.”
