    You check your bank every Monday and still aren't sure you can make payroll in six weeks.

    Most founders check their bank balance and hope for the best. That's not a financial strategy.

    "How many months do I have left?"

    Your balance is a number. What you need is a date, and mental math from a bank tab will not get you there

    Still pasting CSVs from three different tools

    Every export is stale the moment it downloads. Zensus pulls live from every source, no manual imports ever

    "Can I afford to hire?"

    Hires, raises, new tools: every commitment is a bet you cannot test before you make it with real money

    The annual invoice that posted three weeks late

    The hire you made the week before a customer churned

    The cash flow product

    From the macro view to the day it hits.

    Three moves, one cash flow view. Project, ask, get pinged. So you never find out about a cash crunch from a bank balance.

    Alerts

    Get alerted before cash runs out

    Set your cash floor. Zensus watches your 30-day projection and pings Slack the moment it crosses the line. If the breach moves earlier or your minimum balance drops 10%, you get re-alerted.

    • Threshold-based Slack alerts from your projection, not your balance
    • Re-alerts on material change (a week earlier or a 10% dip in minimum balance)
    • Snooze or adjust your threshold from Slack in one click

    Frequently asked questions

    Everything you need to know about Zensus

    Getting Started

    No. You can connect your bank account directly via Plaid, connect QuickBooks, sync your HubSpot subscriptions, or use any combination. No single integration is required to get started.

    Yes. Zensus syncs your HubSpot subscriptions (including annual and quarterly contracts) so your cash flow projections reflect when revenue actually hits your bank, not just flat monthly estimates.

    Under 2 minutes. Connect your bank or QuickBooks with one click, and your cash flow forecast is calculated instantly. No manual data entry.

    Product

    Anything about your finances. Examples: "When will I run out of cash?", "Can I afford to hire two engineers?", "What if we lose our largest annual contract?", "What happens with 5% monthly churn?", "What if we switch a client from monthly to annual billing?"

    Yes. Zensus watches your 30-day projection and fires a Slack alert the moment it drops below a threshold you set. It re-alerts on material change (if the breach moves earlier or your minimum balance drops 10%) and you can snooze or adjust your threshold directly from Slack.

    Your data syncs in real time via webhooks. The moment a transaction clears in Plaid, an invoice changes in QuickBooks, or a subscription updates in HubSpot, your cash flow forecast recalculates. You can also trigger a manual sync from any source at any time.

    Trust & Security

    Yes. All integration tokens are encrypted at rest with AES-256-GCM. Your bank and QuickBooks credentials are never stored on our servers; we rely on OAuth managed by Plaid and Intuit. Every query is isolated by account at the database level, and data sits on encrypted AWS infrastructure.

    Only you. Your financial data is never shared, sold, or used to train AI models. Each account is completely isolated.

    Pricing

    Zensus Pro is $199 a month, billed monthly, cancel anytime. One plan with every integration (Plaid, QuickBooks, HubSpot, Slack), real-time cash flow, scenario modeling, and alerts. Every new account starts with a 14-day free trial. Your card is collected up front but not charged until the trial ends. Cancel anytime before then at no cost. Annual billing is not available yet.

    Stop rebuilding that spreadsheet every Monday.
