How Invoice Automation works

A four-step process that eliminates manual invoice creation while maintaining complete accuracy and control.

1

Job completion signal via Slack

When your team completes a job, they send a message in your designated Slack channel or direct message to the LunarLogic bot. The message format is flexible—team members can write naturally without following rigid templates.

Example messages that work:

  • "Finished cleaning for Acme Corp - $500"
  • "Completed Smith residence job, bill $1,200"
  • "Job done: ABC Company maintenance, invoice for $850"
  • "Done with Jones project - hourly rate 8 hrs @ $125/hr"

The AI parsing engine understands context, handles variations in phrasing, and extracts structured data from unstructured messages. No training required for field staff.

AI extracts invoice details with intelligent matching

LunarLogic's natural language processing engine analyzes the message and extracts all relevant billing information: customer name, job amount, service description, line items, and any special notes or terms.

Intelligent customer matching:

  • Automatically matches customer names to your existing QuickBooks customer database
  • Handles variations, abbreviations, and nicknames (e.g., "ABC" matches "ABC Corporation")
  • Tolerates typos and misspellings using fuzzy matching algorithms
  • Flags new or unrecognized customers for quick review before invoice creation
  • Learns from corrections to improve matching accuracy over time

The extraction process takes less than 5 seconds and achieves 98%+ accuracy on structured data fields. Edge cases are automatically flagged for human review rather than guessing.

Invoice created in QuickBooks with proper formatting

Once data is extracted and validated, LunarLogic creates a properly formatted invoice in your QuickBooks account using the QuickBooks API. All fields are mapped to match your existing setup and configuration.

QuickBooks integration details:

  • Customer billing address, payment terms, and preferences automatically populated
  • Line items formatted according to your service catalog and pricing structure
  • Tax codes, sales tax rates, and jurisdictions applied based on customer location
  • Invoice numbering follows your existing QuickBooks sequence
  • Custom fields, class tracking, and location data preserved
  • Accounting codes and categories mapped to appropriate general ledger accounts

The invoice appears in QuickBooks exactly as if it were manually created by your accounting staff. No special formatting or indicators that it was AI-generated.

Invoice sent to customer automatically

After creation, the invoice is immediately sent to the customer using QuickBooks' built-in email system. This ensures consistent branding and maintains your existing customer communication patterns.

Email delivery options:

  • Sent using your QuickBooks email templates with company branding
  • Customer receives invoice while the job is still fresh in their mind
  • Payment link included for instant online payment via QuickBooks Payments
  • PDF invoice attached for customer records and archiving
  • Email tracking shows when customer opens the invoice
  • Optional CC to your accounting staff for notification

Delivery typically occurs within 90 seconds of the original Slack message. Customers receive invoices same-day instead of waiting for weekly or monthly billing cycles.
