Billing Invoice Reconciliation with Claude Code: Sandbox Policy
A production playbook for billing invoice reconciliation in billing operations using Claude Code: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.
Audience: Billing operations teams
The problem
Billing operations teams need billing invoice reconciliation to run repeatedly against invoices, contracts, usage exports, payment records, and dispute notes. In billing operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Run billing invoice reconciliation in an ephemeral sandbox, keep provider credentials in the broker, expose narrow tools, and store logs outside the workspace for review.
Tradeoffs and failure modes
A narrower runtime blocks ambient machine behavior, but it gives security reviewers a concrete boundary. For billing invoice reconciliation, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
Runtime boundary
filesystem: /skill and /skill/.argo/inputs only
network: deny by default
artifacts: /skill/output/artifacts
logs: retained outside sandbox
