Preparing for Platform Shutdowns: An SLA and Billing Checklist for Your Contracts

Don’t get blindsided by a shutdown: an SLA and billing checklist for procurement and engineering

Hook: You woke up to an email: your collaboration platform is discontinued tomorrow. You need the data, invoices, and a migration path — now. Welcome to 2026, where product sunsetting is becoming a predictable risk for procurement and engineering teams. Use this checklist to negotiate SLAs, exit clauses, data export formats, billing protections, and notice periods so you never scramble when a vendor pulls the plug.

Why this matters in 2026

Late 2025 and early 2026 have shown an acceleration of platform sunsetting and vendor consolidation. Large firms are trimming peripheral products, startups are pivoting faster, and some cloud units are being restructured to cut costs. Case in point: Meta announced it will discontinue the standalone Workrooms app in February 2026, leaving teams that relied on that VR collaboration space with a short runway for data exports and migration. That kind of event is a reminder: procurement and engineering must negotiate defensible exit terms up front.

Trends to factor into negotiations

• Shorter product cycles: Vendors iterate and sunset faster to focus on core AI and hardware bets.
• Regulatory focus on portability: Data portability and interoperability are getting more attention worldwide, making export guarantees easier to defend.
• Egress and billing complexity: Cloud and SaaS billing models have added dynamic egress fees, subscription bundles, and AI usage tiers that can spike costs at exit.
• Vendor consolidation and managed exits: Larger providers may offer managed migration services but often at extra cost — negotiate this in advance.

The top-level checklist: what procurement and engineering must demand

Below is a combined checklist you can use in RFPs, SOWs, and contract negotiations. Split responsibilities between procurement (commercial & legal demands) and engineering (technical verification).

Procurement checklist

1. Clear notice period for service sunsetting
   • Minimum notice: request at least 90 days for non-critical SaaS, 180 days for enterprise platforms with heavy data coupling.
   • Escalation commitment: vendor must notify named contractual contacts and a secondary channel (email and dedicated support portal).
2. Termination rights and exit clauses
   • Termination for convenience with pro rata refund for prepayments and credits for unused services.
   • Termination for product sunsetting guaranteeing post-termination data access windows (see data export clause).
3. Billing protections
   • Pro rata refunds or transferable credits for unused portions of multi-year prepaid contracts.
   • Cap on last-mile egress fees and commitment to publish egress fee schedule 90 days before sunset.
   • Audit rights to review billing and usage data for the prior 12 months.
4. Service level commitments tied to exit
   • During any announced sunsetting period, availability and export APIs must be maintained at production SLAs (e.g., 99.9% availability for export endpoints).
5. Transition assistance and pricing
   • Include a defined number of engineering hours for migration assistance or a fixed-price migration package.
   • Optional: escrow of source code for critical components, or commitment to provide a deployable VM/container image to run for a defined period in an emergency.
6. Vendor lock-in mitigations
   • Mandatory use of open standard export formats, documented export APIs, and provision of a tested export run at contract start and annually.
   • Contractual prohibition on proprietary-only formats as sole export mechanism.

Engineering checklist

1. Data export formats and verification
   • Require exports in machine-readable, documented formats: JSON, CSV, Parquet, SQL dump, and where applicable, OCI/Container images and Helm charts for deployments. See also guidance on export audit logs, metadata, and schema history to help with rehydration.
   • Define schema versions and backwards compatibility guarantees for 12-24 months after release.
   • Schedule a dry-run export and restore during onboarding to validate completeness.
2. RTO and RPO targets for exports and key services
   • RTO and RPO (recovery time objective) for exported datasets: e.g., ability to produce full export within 48 hours for datasets up to X TB; scalable targets for larger datasets.
   • RPO (recovery point objective): guarantee no more than 4 hours of data loss for transactional services during sunset, unless otherwise negotiated.
3. Export automation and access
   • Ensure programmatic exports via authenticated APIs with tokens or IAM roles; include step-by-step runbooks.
   • Provision for bulk export to customer-owned storage (S3-compatible endpoints) to avoid vendor egress lock-in.
4. Key management and encryption
   • Require either customer-managed keys (CMK) or escrow of keys sufficient to decrypt exported data during a sunset window. See security best practices on security & privacy for key handling recommendations.
   • Specify the format and handling of keys, and ensure KMS access is maintained for the data access window.
5. Logs, monitoring, and metadata
   • Export audit logs, metadata, and schema history. These are critical for rehydration and forensic needs.

Concrete SLA metrics and contractual language to ask for

Here are practical SLA items and sample clause templates you can adapt. These are not legal advice; use your legal team to finalize.

Availability and export SLAs

• Export API availability: 99.9% monthly uptime during normal operations; 99.5% during an announced sunset period.
• Export completion time: Vendor must complete a full export of primary datasets within 72 hours for datasets up to 10 TB, with linear scaling commitments for larger datasets.
• Data integrity checks: Exports must include checksums (SHA256) and an export manifest describing schema versions, record counts, and compression used.

Sample contract clause: notice and data export

"If the Vendor elects to discontinue core Platform features or the Platform in its entirety, Vendor shall provide Customer with no less than 180 calendar days prior written notice. During the notice period Vendor shall: (a) make all export APIs, UI exports and related documentation available and functioning at the Production SLA levels described in Exhibit A; (b) provide the Customer one full, verified export of Customer Data in documented, machine-readable formats (including JSON, CSV, and Parquet, and a SQL dump where applicable) at no additional charge; and (c) provide up to 40 hours of transition engineering support at the Vendor's expense, or a fixed-price migration package as agreed in Exhibit B."

Sample clause: billing and refunds

"If the Vendor discontinues the Platform or materially reduces Platform functionality resulting in a forced Customer migration, Vendor shall provide a pro rata refund for prepaid fees for unused service periods and a credit not less than 20% of the unused fees to offset migration costs. Vendor agrees to cap data egress charges to Customer owned endpoints at 0.05 USD per GB during the notice period."

Engineering playbook: what to test during procurement

Procurement can secure contractual protection, but engineering must validate the promises. Add these tests to your onboarding and annual reviews.

1. Onboarding dry-run export
   • Request and execute a full export on Day 30 of the contract. Restore it into a staging environment and verify data, schemas, and auth flows.
2. Automated export scheduling
   • Create CI jobs that use vendor export APIs to fetch incremental exports weekly. Validate checksums and manifest changes.
3. Egress cost simulation
   • Simulate a full data egress to your S3 endpoint and estimate charges. Validate billing explanations and vendor-provided egress caps; pair this with composable billing reviews for unusual charge patterns.
4. Key and encryption recovery rehearsal
   • Test decryption of exported datasets using provided keys or documented CMK processes. Ensure KMS policies allow recovery during an emergency.
5. Restore time validation
   • Time a full restore into a test environment (RTO validation). Confirm that the restored service behaves as expected and that RPO limits are met.

Billing edge cases: what to negotiate hard

• Prepaid contracts and refunds: insist on pro rata refund language and migration credits for forced shutdowns.
• Usage spikes during migration: ensure temporary free uplift for migration-related API calls or a predictable bulk rate.
• Final invoices and debt: require a 90-day dispute window for final usage invoices after an export window closes.
• Multi-year discounts: avoid large prepayments without explicit protections for product discontinuation or change of control buyouts.

Advanced strategies to reduce vendor lock-in

Beyond contractual language, use these engineering and procurement patterns to lower operational risk.

• Push ownership of backups: export to customer-owned object storage on a schedule rather than relying only on vendor backups.
• Use open standards: prefer vendors that support OpenAPI, SQL, OData, GraphQL with introspection, or storage formats like Parquet and Avro.
• Infrastructure as Code export: insist on the availability of IaC manifests (Terraform, CloudFormation, Helm charts) describing deployed resources; tie this to hybrid edge workflows where applicable so you can redeploy locally quickly.
• Escrow and third-party validators: consider third-party code or data escrow for critical services and annual attestation of exportability.
• Operational runbooks: co-develop a shutdown runbook that outlines roles, timelines, export commands, and fallback contact channels.

A short case study and lessons from the Workrooms shutdown

When large platforms discontinue features or entire products, customers often discover gaps between marketing and contractual reality. The Meta Workrooms shutdown in early 2026 illustrated several failure modes: short notice for some users, limited export tooling for immersive assets, and uncertainty about ongoing support for enterprise headsets and managed services. Teams that had negotiated export APIs and transition assistance faced far less disruption than teams that relied entirely on proprietary client-side formats or had large prepayments with no refund clauses.

What worked for customers that survived the transition

• Pre-negotiated export formats and dry-run exports completed during onboarding.
• Contracts that included migration credits and capped egress fees.
• Engineering automation to pull weekly snapshots to customer-owned blob storage.

Actionable takeaways: your negotiation playbook

1. Require a minimum 90–180 day notice period for sunsetting depending on service criticality.
2. Demand export SLAs: 99.9% export API availability, checksummed manifests, 72-hour full export completion for small-medium datasets.
3. Negotiate billing protections: pro rata refunds, migration credits, capped egress fees, and audited billing rights.
4. Test exports during onboarding and automate periodic exports to customer-owned storage.
5. Include transition engineering hours or fixed-price migration services in the contract.
6. Insist on open-standard export formats, IaC manifests, and key management or escrow for decrypting data.

Developer notes and quick scripts

Engineering teams: add a CI job that calls the vendor export API, stores artifacts in S3, and runs a checksum and schema validation. Example outline:

1. Trigger export via vendor API with an OAuth token.
2. Wait for export job completion webhooks or poll export status.
3. Download manifest and data to customer S3 bucket using multipart upload.
4. Run checksum and schema validation and send results to your incident channel.

Final thoughts: plan for shutdowns the way you plan for outages

Sunsetting risk is now part of platform risk, like outages and security incidents. Treat it as such: negotiate the right SLAs, prove exports with dry runs, hold vendors to clear billing protections, and automate your exports. If you do this once as part of procurement onboarding, you save weeks of frantic work and expensive consultants if a vendor decides to sunset a product.
