Rillet + Zapier: 5 Finance Workflows You Can Automate Today

1. Auto-create customers when deals close in your CRM

The problem

• Deal closes in Salesforce or HubSpot
• Someone manually creates the customer record in Rillet
• Until it exists, you can't invoice, run rev rec, or track ARR
• Lag creates downstream errors at close

The workflow

• Trigger: Deal marked Closed Won in Salesforce or HubSpot
• Action 1: Create customer record in Rillet
• Action 2: Notify finance team in Slack (or teams)

Apps: Salesforce or HubSpot + Rillet + Slack (or teams)

2. Trigger invoices when contract milestones are hit

The problem

• Billing tied to milestones, renewals, or usage thresholds tracked outside Rillet
• Someone has to remember to check, then manually create the invoice
• Missed billing cycles, delayed cash collection

The workflow

• Trigger: Milestone marked complete in Linear, Asana, or Notion
• Action: Create invoice in Rillet automatically

Apps: Linear / Asana / Notion + Rillet

3. Route AP approvals through Slack

The problem

• Bills sit in Rillet waiting for approval
• Approver is in Slack (or teams), not checking Rillet
• Someone sends a reminder, approver logs in, bill moves a day late

The workflow

• Trigger: Bill created in Rillet above a set threshold
• Action 1: Send approval request to right person in Slack (or teams)
• Action 2: On approval, bill moves forward in Rillet

Apps: Rillet + Slack (teams)

4. Sync customers from tools outside your native integrations

The problem

• Your billing or subscription tool doesn't have a native Rillet integration
• Customer records have to be created manually between two systems
• Finance plays data entry clerk on every new signup

The workflow

• Trigger: New customer created in billing tool
• Action: Customer record auto-created in Rillet with correct field mapping

Apps: Any billing tool on Zapier + Rillet

5. Notify stakeholders when the books are closed

The problem

• Controller closes the books
• No one outside accounting knows
• CFO has to ask, VP Finance sends a Slack, the CEO wants a summary
• Same three-message conversation every month

The workflow

• Trigger: Period locked in Rillet
• Action: Slack message, teams message or email sent to distribution list with period, closer, and link to report

Apps: Rillet + Slack or teams or Gmail
