Weekly accounts receivable ageing report

Every week, pull open invoices, bucket them by age, render a PDF and email it to finance and account owners.

Building block of the Finance ops agent.

1Is this my problem?

Overdue invoices get chased when someone can see them.

You'll recognise this if…

Overdue invoices noticed late.
Manual AR reviews.
Cash surprises.

Companies affectedBusinesses invoicing customers monthly. Typical fit: seed to 10 staff.

Cost of doing nothing (estimate)Roughly 1–2 hours a week of manual work stays on the team, and the work is done inconsistently.

2Is this solution worth it?

The sources describe how this is built but publish no hard results, so the figures below are our estimates.

Maturity ladder

What each level adds. Most teams start at level 1 or 2 and climb. Highlighted: where this build sits.

Level 1Basic automation
Trigger: every monday. Fixed rules then fetch open invoices, bucket 0-30/31-60/61-90/90+, render pdf. No AI involved.
Level 2AI-assisted
An LLM handles the judgement step (summarise and draft) and a person reviews every output before it is used.
Level 3Autonomous agent
The agent runs end to end on its own and only stops for exceptions. Finance chases.
Level 4Self-learning system
Becomes part of the finance ops agent: Reviewer corrections to coding become examples for the next run, so auto-coding accuracy rises over time.

Level 4 lives in the Finance ops agent: 6 stages with a learning loop.
