What is customer-billing-ops?

A guide for handling subscription billing, from new sign-ups and renewals to upgrades, cancellations, refunds, and churn. It also covers tracking recurring revenue and recording billing changes.

It provides a consistent way to handle billing questions and subscription changes, including prorated charges, credits, payment issues, and customers at risk of leaving.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.01093
Opus 5.5	$0.00017	$0.00437
Sonnet 5.5	$0.00008	$0.00219
Haiku 4.5	$0.00004	$0.00109

Security

Grade A, and why

customer-billing-ops scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Customer Billing Ops

Manage the full subscription lifecycle from signup through renewal, including the hard parts: downgrades, cancellations, refunds, and churn prevention.

Subscription Lifecycle

New Subscription

Confirm plan selection, billing cycle (monthly/annual), and payment method
Set the billing anchor date (first of month, signup date, or custom)
Document trial period length and conversion trigger
Record in the customer record: plan, start date, billing cycle, MRR contribution

Upgrade

Calculate prorated amount for the remaining billing cycle
Confirm the upgrade with the customer (new price, effective date, prorated charge)
Update the subscription record: new plan, effective date, new MRR
Trigger a confirmation email with the updated invoice

Downgrade

Determine effective date (immediate or end of current cycle)
Calculate credit or refund for unused portion if immediate
Confirm feature access changes with the customer
Update the subscription record: new plan, effective date, adjusted MRR
Flag the account for a check-in 30 days after downgrade

Renewal

Send renewal reminder 14 days before the billing date
Verify payment method is still valid
Process the charge on the billing date
Handle failed payments: retry schedule (day 1, 3, 7), dunning emails, grace period

Churn Triage

Identify At-Risk Accounts

Look for these signals:

Usage dropped >50% in the last 30 days
Support tickets increased without resolution
Key user (admin/champion) left the company
Downgrade request submitted
Payment failed and not recovered after first retry
No login in 21+ days
Competitor mentioned in support conversations

Build a Save Offer

Match the save offer to the reason for leaving:

Reason	Save Offer
Too expensive	Offer annual discount, downgrade to lower tier, or pause billing
Not using it enough	Offer onboarding session, extend trial, or reduce to essentials plan
Missing feature	Document the request, share roadmap timeline, offer beta access
Switching to competitor	Ask what they offer that you do not, document for product team
Budget cut	Offer 3-month pause instead of cancellation
Bad experience	Escalate to senior support, offer service credit, schedule a call

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
