Cursor-based pagination for multi-tenant RAG ingestion at 10k documents

·11 views

The article argues that ingestion for a multi-tenant help center should use tenant-scoped cursor pagination over a stable snapshot rather than offset pagination, which becomes a correctness and index-cost problem as content grows. The author describes ingesting documents in bounded pages ordered by update time and document ID, then chunking and upserting vectors with deterministic keys so repeated runs stay idempotent. Page size and chunk size are presented as tunable decisions to be measured against the document mix, not fixed constants. Metadata such as tenant, revision, and access controls is kept with each chunk so retrieval can enforce tenant boundaries before ranking. The piece is written from the perspective of a logistics SaaS workload with carrier rules, customs notes, and warehouse procedures.

Year-End Invoicing Checklist: Timing Tasks Before and After December

Year-end administration often falls behind because it collides with the busy December period, when clients slow down and leftover work piles up. The recommended approach is to sequence tasks: first pursue money that can still be collected before the year closes, then tidy records while there is time to locate missing items. Priorities include billing completed but unbilled work, ranking receivables by age, and separating disputed invoices from merely late ones. Afterward, the focus shifts to checking invoice numbering, storing every issued invoice as a consistently named file, verifying client details, and reconciling partial payments. The checklist is framed as deadlines relative to a business's own year-end, since requirements vary by jurisdiction and entity type.

Four Agency Billing Models and the Unbilled Work Most Firms Miss

Agency invoices must satisfy clients, procurement, and the agency's own cash flow, and most problems stem from unstated rules. The article outlines four billing approaches: retainers billed in advance or arrears, milestone or fixed fees, and time-and-materials. It stresses that each invoice should tie directly to a contract clause or an approved deliverable, with approval details recorded. Pass-through costs should be billed at cost on separate lines with supporting third-party invoices, and any markup agreed upfront. The piece also flags the unbilled work agencies often overlook, along with client-specific invoicing requirements that should be documented once and reused.
