1. AR/AP Aging Analysis

What It Does

Buckets open invoices into aging bands (Current, 1–30, 31–60, 61–90, 90+) and computes exposure at each band.

Input Format

Accepts CSV, JSON, or inline data with at minimum:

invoice_id
client_name (or vendor_name for AP)
invoice_date
due_date
amount
amount_paid (optional; defaults to 0)

2. Automated Follow-Up Sequencing

Sequence Logic

How to Trigger

"Draft follow-up emails for all invoices 30+ days past due" "Generate a Stage 2 follow-up for Acme Corp Invoice #1042" "What's the next action for client Beta LLC?"

3. Payment Matching

Logic

Matches incoming payments to open invoices using:

Exact match — payment amount = invoice amount (highest confidence)
Partial match — payment covers multiple invoices (sum match within tolerance)
Fuzzy match — memo/reference field matches invoice ID or client name
Unmatched — flag for manual review

Input

Bank feed export or payment notification data
Open invoice list

Output

PAYMENT MATCHING RESULTS — 2026-03-15
======================================
Payment ID  Amount    Matched To         Confidence  Status
──────────────────────────────────────────────────────────
PMT-2201    $4,200   INV-1042 (Acme)    HIGH        ✅ Matched
PMT-2202    $10,000  INV-1038 + INV-1039 MEDIUM     ⚠️  Review
PMT-2203    $750     —                  NONE        ❌ Unmatched

How to Trigger

"Match today's payments to open invoices: [paste bank data]" "We received $10k from Beta LLC — which invoices does that cover?" "Show me all unmatched payments this month"

4. Collection Priority Matrix

Scoring Factors

Factor	Weight	Description
Days past due	40%	Older = higher priority
Invoice amount	30%	Larger balances prioritized
Client payment history	20%	Chronic late payers scored higher
Dispute flag	10%	Disputed invoices deprioritized

Priority Tiers

Score	Tier	Action
80–100	🔴 Critical	Immediate escalation, daily follow-up
60–79	🟠 High	Weekly follow-up, payment plan offer
40–59	🟡 Medium	Standard sequence, monitor
0–39	🟢 Low	Automated reminder only

Output

COLLECTION PRIORITY MATRIX — 2026-03-15
=========================================
Rank  Client        Invoice     Amount    DPD   Score  Tier
─────────────────────────────────────────────────────────────

"Generate collection priority matrix from current AR aging" "Who should we call first today?" "Score this invoice list for collection priority"

5. Workflow Examples

Full AR Review

User: Run full AR review — aging, priorities, and draft follow-ups for top 3 past due.
Sam: [Runs aging] → [Scores matrix] → [Drafts 3 follow-up emails by stage] → presents for approval

Single Client Deep Dive

User: Full invoice status for Acme Corp
Sam: [Pulls all open invoices] → [Aging position] → [Payment history] → [Next action recommendation]

Payment Application

User: Got a $12,700 wire from Acme — apply it
Sam: [Matches to INV-1021 $8,500 + INV-1042 $4,200] → [Confirms match] → [Notes for QBO entry by human]

6. Negative Boundaries — When NOT to Use

❌ Do not enter or post transactions in QBO, Xero, or any client accounting system (read-only rule)
❌ Do not send follow-up emails without Irfan reviewing and approving drafts first
❌ Do not make collection calls (use output as briefing for human follow-up)
❌ Do not write off bad debt or adjust invoice balances without explicit instruction
❌ Do not resolve billing disputes — flag and escalate to Irfan
❌ Do not use for payroll, tax filings, or regulatory submissions (use compliance-monitor skill)
