Stop chasing invoices. The system that dropped collection time from 34 days to 12—without expensive software or awkward phone calls.
Stop Chasing Invoices. The AR Automation Playbook That Cut Collection Time by 65%.
"Just checking in on invoice #4521..."
You've sent that email 47 times this year. You hate writing it. Your clients hate receiving it. And your cash flow is still a disaster.
Here's the uncomfortable truth: If you're manually chasing invoices, you're leaving money on the table and burning hours you'll never get back.
Last month, we helped a 15-person agency cut their average collection time from 34 days to 12. They stopped writing "friendly reminder" emails. Their cash flow stabilized. And they got back 8 hours a week.
Here's exactly how.
The Cost of Manual AR (It's More Than You Think)
Let's do the math on what invoice chasing actually costs:
Time spent:
Per overdue invoice:
- Write reminder email: 10 minutes
- Follow up when ignored: 10 minutes
- Track in spreadsheet: 5 minutes
- Escalate to manager: 15 minutes
- Final collection effort: 20 minutes
Average total per late invoice: 60 minutes
Multiply it out:
Monthly invoices: 50
Late payment rate: 40% (industry average)
Late invoices per month: 20
Time chasing: 20 hours/month
At $50/hour: $1,000/month just chasing payments
Plus the hidden costs:
- Cash flow uncertainty (can't plan)
- Awkward client relationships
- Stress and frustration
- Opportunity cost (what else could you do with 20 hours?)
Why Clients Pay Late (It's Not What You Think)
Before we fix the process, understand why invoices go overdue:
Reason 1: They Forgot (40% of cases)
Your invoice arrived. They meant to pay it. Life happened. It's sitting in an email folder they never opened.
Fix: Automated reminders before and after due date.
Reason 2: Friction (30% of cases)
They need to:
- Find the invoice
- Log into their bank
- Enter payment details manually
- Get approval from someone else
Every step is a chance to abandon.
Fix: Make paying stupid easy. One-click payment links.
Reason 3: Cash Flow Issues (20% of cases)
They don't have the money right now. They're hoping you'll forget.
Fix: Early identification + payment plan options.
Reason 4: Dispute (10% of cases)
Something's wrong. The amount, the scope, the work quality.
Fix: Fast escalation to resolve issues before they fester.
The 5-Part AR Automation System
Part 1: Invoice Delivery That Gets Noticed
The problem: Invoices go to spam. Or get buried. Or go to the wrong person.
The fix:
Step 1: Multiple delivery channels
When invoice is created:
1. Email to billing contact (with PDF attached)
2. Email to main contact (CC, no attachment)
3. Slack/Teams notification (if integrated)
4. SMS alert for invoices over $X (optional)
Step 2: Smart subject lines
Bad: "Invoice #4521 from [Company]"
Good: "[Company] Invoice Due [Date] - $[Amount] - [Project Name]"
The recipient should know exactly what it is and when it's due without opening.
Step 3: One-click payment link
Every invoice includes:
- Direct payment link (Stripe, PayPal, etc.)
- Auto-filled amount
- No login required
Reduce payment to: See email → Click link → Confirm
Part 2: The Pre-Due Date Nudge
The problem: You wait until invoices are late to do anything.
The fix: Remind before the due date.
Automation sequence:
Invoice sent: [Day 0]
→ Track in system
Day 7 (or 3 days before due):
→ Send friendly reminder
→ Subject: "Quick reminder: Invoice due [date]"
→ Body: "Just a heads up - payment link below"
Day before due:
→ Send final reminder (if not paid)
→ Subject: "Due tomorrow: $[amount]"
Template (pre-due reminder):
Subject: Quick reminder: Invoice due [date]
Hi [Name],
Just a quick reminder that invoice #[number] for $[amount]
is due on [date].
Pay now with one click: [PAYMENT LINK]
Questions about this invoice? Just reply to this email.
Thanks,
[Your name]
Why this works:
- 30% of invoices get paid from pre-due reminders
- No awkwardness (it's not late yet)
- Shows you're organized and professional
Part 3: The Post-Due Escalation Ladder
The problem: You send one "friendly reminder" and hope for the best.
The fix: Systematic escalation that gets progressively firmer.
The escalation sequence:
Day 1 overdue:
→ Friendly reminder (automated)
→ Tone: "Looks like this slipped through"
Day 7 overdue:
→ Firmer reminder (automated)
→ Tone: "Please prioritize this"
→ CC: Internal account manager
Day 14 overdue:
→ Personal outreach (account manager call)
→ Task created: "Call [client] about overdue invoice"
→ Tone: "Let's resolve this together"
Day 21 overdue:
→ Formal notice (automated)
→ Tone: "Payment required to continue services"
→ Internal alert to leadership
Day 30 overdue:
→ Final notice before escalation
→ Pause new work (if applicable)
→ Offer payment plan option
Day 45+ overdue:
→ Collections process begins
Templates:
Day 1 (Friendly):
Subject: Friendly reminder: Invoice #[number] is overdue
Hi [Name],
I noticed invoice #[number] for $[amount] is now past due.
Sometimes these slip through the cracks!
Pay now: [PAYMENT LINK]
If there's an issue with this invoice, please let me know
and we'll sort it out.
Best,
[Name]
Day 7 (Firmer):
Subject: Action needed: Invoice #[number] - 7 days overdue
Hi [Name],
Invoice #[number] for $[amount] is now 7 days overdue.
Please process this payment at your earliest convenience:
[PAYMENT LINK]
If you're experiencing any issues or have questions about
this invoice, please reach out directly.
Thank you,
[Name]
Day 14 (Escalation):
Subject: Urgent: Invoice #[number] - 14 days overdue
Hi [Name],
I'm reaching out directly because invoice #[number] for
$[amount] is now 14 days past due.
I'd like to resolve this quickly. Can we schedule a brief
call to discuss? [CALENDAR LINK]
Alternatively, you can pay now: [PAYMENT LINK]
Please respond by [date] so we can avoid any service
disruptions.
Thank you,
[Name]
Part 4: Real-Time Visibility
The problem: You don't know which invoices are at risk until they're severely overdue.
The fix: Dashboard that shows AR health at a glance.
Build a simple tracker (Google Sheet or Notion):
| Invoice | Client | Amount | Sent | Due | Status | Days | Risk |
|---------|--------|--------|------|-----|--------|------|------|
| 4521 | Acme | $5,000 | 11/1 | 11/15 | Paid | - | ✓ |
| 4522 | Beta | $3,000 | 11/5 | 11/19 | Overdue | 7 | ⚠️ |
| 4523 | Gamma | $8,000 | 11/10 | 11/24 | Due Soon | -3 | - |
Automate the updates:
Trigger: Daily at 9 AM
Check all open invoices:
- Calculate days until/since due
- Update status column
- Color code by risk level
- Send Slack summary: "AR Update: 5 paid, 3 overdue, 2 at risk"
Weekly AR review:
Every Monday:
- Total outstanding
- Average days outstanding
- At-risk amount
- Required actions this week
Part 5: Exception Handling
The problem: Not every late invoice is the same. Some need human judgment.
The fix: Route exceptions appropriately.
Exception rules:
If invoice > $10,000 AND > 7 days overdue:
→ Immediate alert to leadership
→ Personal call required within 24 hours
If client has 2+ overdue invoices:
→ Flag as "at risk" relationship
→ Account manager review required
If client responds with dispute:
→ Pause automated sequence
→ Create task for resolution
→ Track separately
If client requests payment plan:
→ Route to finance for approval
→ Create custom payment schedule
→ Adjust automation accordingly

Common Objections (And Why They're Wrong)
"My clients will think I'm pestering them"
Automated, professional reminders aren't pestering. They're expected. Your clients get automated reminders from every SaaS tool, credit card, and utility company.
What's actually annoying: Inconsistent, emotional follow-ups that make everyone uncomfortable.
"I need to handle each client personally"
No, you don't. You need to handle exceptions personally. The 80% of invoices that just need a reminder? Let the robots handle it.
Save your personal touch for relationships that need it.
"What if something goes wrong?"
Build in safeguards:
- Human review for large amounts
- Pause automation on dispute
- Override capability for special cases
The system handles the routine. You handle the exceptions.
"We don't have that many invoices"
Even 20 invoices/month × 30 minutes average chasing = 10 hours/month.
That's a day and a half you could spend on literally anything else.

Frequently Asked Questions
What is accounts receivable automation and how does it work?
Accounts receivable automation uses software to handle invoice delivery, payment reminders, escalation sequences, and tracking without manual intervention. The system automatically sends pre-due reminders, progressively firmer post-due follow-ups, routes exceptions to the right people, and tracks everything in a real-time dashboard—reducing manual invoice chasing from 20 hours/month to under 1 hour.
How much does AR automation cost for a small business?
Basic AR automation costs $20-50 per month using tools you likely already have: your accounting software (QuickBooks/Xero), Zapier ($20/month), Google Sheets or Notion (free), and payment processing (Stripe at 2.9% per transaction). This minimal investment typically reduces collection time by 60%+ and frees up 15-20 hours monthly that was spent manually chasing payments.
What's the best way to automate payment reminders without annoying clients?
Send pre-due reminders 3-7 days before the due date (friendly and helpful), then post-due reminders at days 1, 7, 14, 21, and 30 with progressively firmer tones. Include one-click payment links in every email and keep messages professional and automated-looking. Clients expect automated reminders—they get them from every SaaS tool and credit card company—so consistent, systematic follow-up is more professional than awkward manual outreach.
Why do clients pay invoices late and how can automation fix it?
Most late payments (40%) happen because clients simply forgot—automation fixes this with timely reminders. Another 30% are due to payment friction—automation solves this with one-click payment links. 20% stem from cash flow issues—automation catches these early so you can offer payment plans. Only 10% are actual disputes—automation escalates these immediately for human resolution before they fester.
How fast can I reduce my average invoice collection time with AR automation?
Most businesses see a 20-30% reduction in collection time within the first month of implementing AR automation. By month three, expect 40-50% reduction as the system optimizes. Within six months, companies typically achieve 60%+ improvement—like the 15-person agency we helped that dropped from 34 days average collection to 12 days, freeing up $45,000 in working capital.
Can I automate accounts receivable without replacing my accounting software?
Yes, you can layer automation on top of any accounting software using Zapier or Make.com to connect your existing tools. The automation handles the reminder sequences, tracking, and alerts while your accounting software remains the source of truth for financial data. You don't need expensive dedicated AR software—just smart connections between the tools you already use.
Cash Flow Is Operations
Every day an invoice sits unpaid is a day you can't invest in growth, can't make payroll stress-free, can't take advantage of opportunities.
AR isn't a finance problem. It's an operations problem. And like every operations problem, the solution is: systematize, automate, and get out of the way.
Stop writing "friendly reminder" emails. Start getting paid.
