| Tool | What it does |
|---|---|
| invoice_register | Start chasing an unpaid invoice: client, reference, amount, currency, due date. Returns DUN-YYYY-NNNN and the three escalation dates |
| payment_record | Record money received, full or partial. A part payment lowers what the next letter asks for; covering the balance closes the ladder |
| letter_render | Generate the chase letter for the current stage -- reminder 1, reminder 2 or the final notice -- as Markdown or self-contained printable HTML. Nothing is… |
| letter_sent | Record that a letter actually went out, with its date, so the ladder advances. Letters go out in order |
| overdue_list | Every unpaid invoice past its due date: days late, outstanding, letters sent, what is due next, worst first |
| aging_summary | The whole register in current/1-30/31-60/61-90/91+ buckets, counts and totals in integer cents, per currency |
| chase_today | The day's chase list: which invoices cross an escalation threshold today, which letter to send each, what falls due next |
| invoice_status | One chased invoice in full: payments, letters, schedule, next action |
| invoice_delete | Delete an invoice entered wrongly. The id is not reissued |
