What This Workflow Does

This automation eliminates the manual process of creating new clients in Harvest, your time tracking and invoicing platform. Instead of logging into Harvest and filling out forms for each new client, this workflow automatically creates complete client records with all necessary details.

The template handles the entire client creation process programmatically, including setting up billing information, tax settings, and project associations. It ensures consistency across all client records while saving your team hours of repetitive data entry work.

How It Works

1. Trigger Setup

The workflow begins when a new client needs to be created, triggered by events like a signed contract, CRM entry, or form submission. The trigger passes all necessary client details to the workflow.

2. Data Preparation

The workflow formats and validates the incoming data to match Harvest's requirements. It checks for missing fields, standardizes formats, and applies business rules for client categorization.

3. API Connection

Using Harvest's API, the workflow authenticates and establishes a secure connection to your Harvest account. This ensures the client creation happens in your actual production environment.

4. Client Creation

The workflow sends the prepared client data to Harvest's API, creating a complete client record with all specified details. It handles all required fields while maintaining data integrity.

5. Confirmation & Logging

After successful creation, the workflow generates a confirmation message and logs the new client details. This provides an audit trail and allows for follow-up actions if needed.

Frequently Asked Questions

Common questions about Harvest integration and automation

Automating client creation in Harvest saves significant administrative time while reducing data entry errors. When onboarding new clients, automation ensures consistent record creation with all required fields populated correctly. This eliminates manual copy-pasting between systems and maintains data integrity across your financial operations.

For agencies onboarding 20+ clients monthly, this automation can save 50+ hours annually. The standardized process also improves billing accuracy and reduces follow-up questions from clients about missing or incorrect information.

  • Saves 10-15 minutes per client creation
  • Reduces billing disputes from incorrect setups
  • Ensures compliance with your financial processes

To automate client creation in Harvest, you'll typically need the client's name, contact information, billing details, and project specifics. The workflow can pull this data from CRM systems, intake forms, or email communications. Common fields include company name, address, currency preference, payment terms, and tax settings.

The workflow handles both required fields and optional enhancements like default invoice templates or custom fields. For example, law firms might automate state bar number inclusion, while marketing agencies could preset creative review workflows.

  • Minimum required: Client name and currency
  • Recommended: Billing address and payment terms
  • Optional: Tax IDs, custom fields, notes

Yes, Harvest's API allows integration with CRM platforms like HubSpot or Salesforce, accounting software like QuickBooks, and project management tools. This enables automatic client creation whenever a new deal closes or a contract is signed in connected systems, creating a seamless workflow across your tech stack.

A common implementation connects Salesforce opportunities to Harvest. When a deal reaches "Closed Won" stage, the workflow creates the client in Harvest, sets up the initial project, and notifies the account manager - all without manual intervention.

  • Sync with CRM deal/contact records
  • Connect to contract signing platforms
  • Trigger from payment processor activations

Automated client setup ensures proper categorization from day one, making financial reporting more accurate. It syncs client data with accounting systems, eliminates duplicate entries, and provides audit trails. This standardization reduces reconciliation time and improves billing accuracy throughout the client lifecycle.

When accounting teams receive properly configured Harvest clients, they spend less time correcting billing details or chasing missing tax IDs. The automation can enforce your firm's standard payment terms and invoice templates across all clients.

  • Reduces month-end reconciliation work
  • Ensures proper tax handling from inception
  • Maintains consistent billing practices

Common triggers include new CRM contact creation, signed contract notifications, completed intake forms, or payment processor activations. The workflow can also be scheduled to batch process multiple clients at specific times, or triggered manually via webhook for special cases requiring human review first.

Consulting firms often trigger from signed SOW documents, while e-commerce agencies might connect to Shopify store creations. The flexibility allows customization to your specific client acquisition workflow while maintaining automation benefits.

  • CRM deal stage changes
  • Electronic signature completions
  • Form submissions or payment receipts

Automated workflows use Harvest's secure API with OAuth authentication. Sensitive data like billing information is encrypted in transit. Access controls ensure only authorized systems can create clients. Audit logs track all automated creations, and workflows can include approval steps for high-value clients before final creation.

The workflow template follows security best practices by never storing credentials in plaintext and implementing proper rate limiting. You can further enhance security by restricting API key permissions and implementing IP whitelisting for production workflows.

  • OAuth2 authentication protects access
  • Data encrypted in transit (HTTPS)
  • Detailed audit logs maintained
