AR Automation: Getting Paid Faster

The best way to collect faster is to make paying easy and inevitable. AR automation removes friction from the payment process: invoices arrive instantly, payment options are clear, reminders go out automatically, and payments match to invoices without manual effort. The result is faster collection, less staff time, and happier customers.

Manual AR processes create delays at every step. Invoice generation takes time. Delivery confirmation is uncertain. Follow-up requires someone to remember. Payment matching is tedious. AR automation eliminates these delays.

But AR automation isn't just about speed—it's about consistency. Automated systems follow up on every invoice, every time. No invoices fall through the cracks. No customers get forgotten.

or time tracking

What AR Automation Does

Invoice Generation

Automatically create invoices from source data:

  • From sales orders: Convert order to invoice when shipped
  • From contracts: Generate recurring invoices on schedule
  • From time tracking: Create invoices from billable hours
  • From project milestones: Trigger invoices when milestones complete

Invoice Delivery

  • Email delivery: Send invoices electronically with confirmation
  • Portal posting: Make invoices available in customer portal
  • EDI integration: Send directly to customer AP system
  • Multi-channel: Support customer-preferred delivery method

Payment Processing

  • Payment portal: Customer self-service payment
  • Multiple methods: ACH, credit card, check
  • Auto-pay: Set up recurring payment for repeat customers
  • Payment links: One-click payment from invoice

Automated Reminders

  • Pre-due reminders: Gentle nudge before due date
  • Due date notice: "Your invoice is due today"
  • Past-due sequence: Escalating reminders after due date
  • Customizable: Adjust timing and tone per customer

Cash Application

  • Auto-match: Match payments to invoices by reference
  • AI matching: Match based on amount, customer, timing
  • Partial payments: Apply correctly and track remaining
  • Exception handling: Flag unmatched payments for review

Benefits of AR Automation

Faster Collection

  • Instant invoicing: Invoice goes out same day as delivery
  • Easy payment: Pay button on invoice reduces friction
  • Consistent follow-up: Every invoice gets reminders
  • Typical impact: 5-15 day reduction in DSO

Time Savings

  • Invoice creation: Auto-generate vs. manual creation
  • Follow-up: Automated reminders vs. manual tracking
  • Cash application: Auto-match vs. manual reconciliation
  • Typical impact: 40-60% reduction in AR staff time

Reduced Errors

  • Accurate invoices: Pull from source data, no retyping
  • Complete delivery: Confirmation that invoice was received
  • Correct application: Payments match right invoices

Impact Example

A company with $10M revenue and 45-day DSO has $1.23M tied up in AR. Reducing DSO to 35 days through automation frees up $274K in working capital. At 10% cost of capital, that's $27,400 annual benefit—before counting staff time savings.

Automated Dunning Sequences

Dunning is the process of communicating with customers about payment. Automation makes it consistent and persistent without being aggressive.

Sample Dunning Sequence

Day -7: "Friendly reminder: Invoice #123 will be due in one week."

Day 0: "Invoice #123 is due today. Pay now with one click."

Day +7: "Invoice #123 is now past due. Please remit payment."

Day +14: "Second notice: Invoice #123 is 14 days past due."

Day +21: "Urgent: Please contact us regarding overdue invoice."

Day +30: "Final notice before collection action."

Customization Options

  • Timing: Adjust intervals based on customer type
  • Tone: Friendly vs. formal based on relationship
  • Channel: Email, SMS, phone call at different stages
  • Exclusions: Pause for customers with known issues or disputes

Key Principles

  • Start early: Pre-due reminders are most effective
  • Stay consistent: Same cadence for everyone (unless customized)
  • Be helpful: Include payment link in every message
  • Know when to escalate: Move to personal contact for large/old amounts

Payment Portals

A payment portal lets customers pay invoices online—anytime, without human interaction.

Portal Features

  • Invoice viewing: Customer can see all invoices and status
  • Payment options: ACH, credit card, sometimes check request
  • Payment history: View past payments and receipts
  • Statement download: Account statements on demand
  • Auto-pay setup: Enroll in automatic payment

Benefits

  • 24/7 availability: Customers pay when convenient for them
  • Reduced inquiries: Self-service for common questions
  • Faster payment: No delays from manual processing
  • Payment certainty: Card/ACH payments are immediate

Payment Links vs. Portals

Payment links (in invoice emails) are simpler—one click to pay one invoice. Payment portals are richer—view all invoices, manage account. Start with payment links; add portal as you scale.

Communicate with Customers

Before launching automated reminders, inform customers. "We're improving our invoicing system. You'll now receive invoices electronically with easy payment options, and automated reminders as a courtesy." This prevents confusion and positions automation positively.

Measuring Success

Key Metrics

  • DSO trend: Days sales outstanding should decrease
  • Aging improvement: Less AR in older buckets
  • Collection rate: % collected within terms
  • Email open rates: Are reminders being seen?
  • Portal adoption: % of customers paying online

Monitoring Dashboard

Track these weekly or monthly:

  • DSO current vs. prior period vs. target
  • Aging report (current, 30, 60, 90+)
  • Invoices sent vs. invoices paid
  • Average time to payment
  • Bad debt write-offs
