Inputs per run
- All open invoices with amount, age, and due date
- Customer payment history (average days to pay)
- Prior follow-up thread history if available
- Business tone guide for collection messages
- Priority rules (e.g., >$500 and >30 days = urgent)
Expect
AI outputs
- Prioritized collections queue with urgency score
- Draft follow-up email per invoice (escalating tone by age)
- Summary of total AR and aging buckets
- Flag for disputes or credits needed before contacting
- Suggested call vs email channel per customer
Business problem
Outstanding invoices pile up because owners avoid awkward collection conversations — cash sits in AR while they focus on delivery work.
Expected outcome
Weekly prioritized collections list with suggested follow-up emails ranked by amount, age, and customer payment history — drafts ready for owner approval.
Who it's for: B2B service businesses and clinics with net-30 invoicing and $10K+ in outstanding AR at any time.

System behavior
- Weekly batch — not real-time on invoice creation
- Draft-only emails — owner must approve and send
- Escalates tone at 30/60/90 day marks per policy
- Skips customers with open disputes or credit memos
- Collections support only — not legal debt collection
No-code vs low-code vs custom
No-code
Lowest effort
Non-technical owners, quick validation, under 50 runs/day
3 options listed
Low-code
Medium effort
Operators comfortable with Zapier/n8n, need more control
3 options listed
Custom build
Highest effort
High volume, custom logic, or strict data privacy requirements
4 options listed
| No-code options | Low-code options | Custom build stack |
|---|---|---|
| QuickBooks overdue report + ChatGPT draft emails | n8n weekly: QBO AR aging → OpenAI → Gmail drafts | QuickBooks/Xero API AR query |
| Zapier: QBO overdue trigger → GPT → Gmail draft | Make.com overdue invoice workflow | Customer history join from CRM |
| HubSpot sequences with AI-generated copy | Xero + GPT collections assistant | OpenAI with escalating tone templates |
| — | — | Gmail draft API — never auto-send without approval |
Start with no-code to validate the workflow. Move to low-code when you hit rate limits or need branching logic. Custom build when volume, privacy, or integration depth requires it.
Step-by-step implementation
- 1Connect accounting system and email
- 2Define aging buckets and escalation tone rules
- 3Pull open invoices weekly
- 4Generate prioritized queue and drafts
- 5Owner reviews and sends — track responses in spreadsheet
- 6Measure DSO monthly to tune priority rules
Risks and limitations
- Aggressive collection tone can damage client relationships
- AI may contact wrong person if CRM data is stale
- Legal collection limits vary — this is friendly AR follow-up only
- Writing off bad debt still requires human judgment
