Enterprise logos ghosting payments and mid-tier tenants loading triple the seats they bought are not churn—they’re enforcement problems. Use this console to separate unpaid invoices from license misuse, quantify leverage from your contracts and logs, and spin up demand letters without law-firm overhead.

Two Problems

Debt (missed invoices) vs scope creep (unlicensed users/features). Different facts, different leverage.

Contract Hooks

Order forms/MSAs define billing and late-fee mechanics; license grants limit users, entities, territories.

Telemetry Matters

Seat logs, API counts, and environment IDs beat accusations. Audit-quality data drives compliance conversations.

Escalation Ladder

Reminders → pre-collections notice → demand letter → suspension/collections/legal. Stick to the ladder.

Pro tip: Keep your MSAs updated so you can point to actual clauses (“fees due 30 days net,” “license limited to 100 named users”) instead of vague expectations.
Escalation Readiness: Moderate Client is 45+ days past due, reminders ignored—prep demand letter with suspension warning.

Toggle facts that apply:

Invoices >30 days overdue
Multiple reminder emails unanswered
Contract gives right to suspend on non-payment
Customer disputes invoice accuracy
Finance confirmed receipt / no payment plan
Recent promise to pay with date
When to send
Demand letters come after your dunning cadence and account manager nudges fail. Amount should be meaningful, due dates clear, and you prepared to act (suspend, collections) if ignored.
What to cite
Agreement name/ID, invoice numbers/dates, payment terms (“Net 30”), prior reminder dates, exact total due, deadline, next steps (suspension, collections, suit).([retrievables.com][1]; [Upflow][6])

License Anatomy

Grant: limited, non-transferable, defined metrics (users/seats/environments). Restrictions: no resale, no sharing, no external users without consent.([Enzuzo][2])

Evidence Pack

Seat telemetry, API logs, environment IDs, SSO metadata, screenshots. Summarize: licensed vs observed usage.

Overuse Impact

Can trigger both breach of contract and (if conditions in grant) copyright claims.([Google GitHub][5]; [Romano Law][3])

Resolution Paths

True-up purchase, reduce usage, or formal audit/suspension if stonewalled. Offer cooperative cure before escalating.

When letter beats audit
Use letters when telemetry is clear, customer is mid-market, and you prefer a fast true-up over dragging everyone through a full audit. Save audits for repeat offenders or strategic accounts.
Key clauses to quote
Named-user cap, environment limitations, affiliate/third-party restrictions, geographic scope, “no sharing credentials,” audit rights, remedies upon breach.([Larsen Law Offices, LLC][10])

Unpaid Invoice Letter

Subject: Outstanding Subscription Invoices – [Product]

Hello [Name],

Under [Agreement/Order], we provide [service] in exchange for invoices due Net [X]. The following remain unpaid:
• Inv #[ ] dated [ ] – [amount]
• Inv #[ ] dated [ ] – [amount]
Total past due: [ ]

We’ve sent reminders on [dates] without response. Please pay the full balance by [deadline] or send a concrete plan the same day. If there’s a billing error, detail it in writing so we can review.

Absent resolution, we’ll consider suspension, referral to collections, and other contractual remedies. We’d prefer to keep the account in good standing—let us know how you’d like to proceed.

License Misuse Letter

Subject: License Compliance for [Product]

Hello [Name],

Our agreement dated [ ] limits use of [Product] to [licensed metrics]. Usage data over the past [period] shows average [observed metric], exceeding your entitlement by ~[percent]%. Example: order covers 100 seats; telemetry shows 178 unique active users tied to your domain.

This overdeployment isn’t authorized. To resolve it, please either (a) acknowledge the overuse and agree to purchase the additional [metric] plus a true-up for the past [period], or (b) reduce usage to within scope and confirm you’ve done so. Please respond by [deadline].

If we don’t hear from you, we may exercise audit rights, suspend unlicensed access, or pursue remedies available under the contract and applicable IP laws. We’d much rather fix this collaboratively—happy to review the data with your team.

Tone check: Keep it factual, give a path to cure, and reserve rights. Threats without willingness to act undermine credibility.
