LIVE AUTOMATION FLOW
⚡️ Trigger — Invoice due
Fires when invoice crosses due date
⏱ Wait · 3 days
Delay before first reminder
? Condition — Still unpaid?
Branch: yes → continue / no → stop
✉️ Send · Email + SMS
Professional overdue reminder sent
✓ Stop — Payment detected
All reminders cancelled instantly
RELIABILITY
Reliability your team can trust
The engine runs so your people don't have to. Set it once, and every invoice gets the same professional, timely follow-up every time.
TRIGGERS
Trigger-based automation
Automation begins the moment something changes — no manual intervention, no cron jobs, no guesswork.
Invoice due / overdue
Fire when an invoice crosses its due date or passes a configurable overdue threshold.
Payment received
Cancel sequences instantly the moment a payment lands — zero chance of sending a reminder after payment.
Contact event
React to new contacts, API signals, replies, or custom webhook events from your other systems.
LOGIC
Delays and conditional logic
Wait hours or days between steps, branch on whether an invoice is still unpaid, and tailor the path for each contact — all configured visually. No code required.
- Set exact wait durations between steps
- Branch by payment status, channel, or custom field
- Stop immediately when a condition is met
WAIT
ONLY IF
CHANNEL
ON PAYMENT DETECTED
CHANNELS
Multi-channel execution
Email and SMS work together in a single flow. Lead with email, escalate to SMS when it matters, and never double-send across channels.
Maximum one reminder per day per invoice — professional pacing, always.
Retry and delivery safeguards
Transient failures are retried automatically. Hard bounces are flagged. Rate limits are respected. The engine is built to deliver reliably without you babysitting it.

ARCHITECTURE
API-driven architecture
Everything is event-driven. Each invoice change, payment, and contact action is an event the engine reacts to. On the Pro plan, hook into the same API yourself.
- Webhook support for external triggers
- Real-time event processing
