HeysenDocumentation for Heysen — the multi-tenant platform US life-insurance brokerages run on. Agent handbook, commission semantics, and data-delivery rules.https://doc.heysen.io/enVersioned source data — read one version, never sum themhttps://doc.heysen.io/blog/versioned-source-data-one-version/https://doc.heysen.io/blog/versioned-source-data-one-version/Our source replica is append-only, so "what does this record say now" is the highest version and not a sum. A delivery that added second versions showed us why that rule needs a guard, not a comment.Sat, 26 Sep 2026 00:00:00 GMTdataincidentsengineeringHeysen EngineeringWhat a reconciliation gate actually protectshttps://doc.heysen.io/blog/what-a-reconciliation-gate-protects/https://doc.heysen.io/blog/what-a-reconciliation-gate-protects/Hashes prove a file arrived intact. They cannot prove the file was computed correctly.

What we do when the feed does not arrive, and why "delayed" is better than a stale number with no label.Wed, 16 Sep 2026 00:00:00 GMTdataproduct-decisionsHeysen EngineeringWhy your commission number has one source of truthhttps://doc.heysen.io/blog/why-your-commission-number-has-one-source-of-truth/https://doc.heysen.io/blog/why-your-commission-number-has-one-source-of-truth/An agency can load its own income results, a processor can approve results, and legacy settlements can exist all at once. Here is why we show one number and label where it came from.Sat, 12 Sep 2026 00:00:00 GMTtruecommissiondataproduct-decisionsHeysen EngineeringLicense holders vs the producer who earned the commissionhttps://doc.heysen.io/blog/license-holders-vs-the-producer-who-earned-the-commission/https://doc.heysen.io/blog/license-holders-vs-the-producer-who-earned-the-commission/Some agencies route every policy through a few licensed holders while somebody else writes the business. Modelling that honestly takes two separate mechanisms — and one of them is not about policies at all.Tue, 08 Sep 2026 00:00:00 GMTattributioncomplianceHeysen Engineering
