Diagnostic and pathology labs live and die by turnaround time and result accuracy, but ERPNext core has no laboratory information system. The stock Healthcare module gives you patients, encounters, and a basic Lab Test DocType, yet it stops well short of a real LIS: there is no barcoded specimen chain of custody, no panel-to-analyte decomposition, no per-analyte reference ranges by age and sex, no critical-value flagging, no analyzer interface, and no referral-doctor commission accounting. Labs end up gluing these gaps together with spreadsheets, WhatsApp result sharing, and manual PDF editing — which is exactly where samples get mislabeled and reports go out wrong.

ECOSIRE builds a proper Frappe application (its own app in apps/, installed on your bench, with a dedicated module and namespaced DocTypes) that layers a full LIS workflow onto ERPNext without forking core. We model a Lab Test Catalog and Test Panel structure where a panel expands into its component analytes, each analyte carrying units, method, and a Reference Range child table keyed by sex and age band so the correct normal range is resolved automatically at result-entry time. Ordering flows from a Test Requisition DocType that links to the ERPNext Customer/Patient, prices against a standard Price List, and — via a hooks.py on_submit doc event — auto-generates one Sample record per required specimen type with a printable barcode label (Code128) and a unique accession number from a Frappe naming series.

Sample tracking is a real state machine: Collected → In-Transit → Received → In-Process → Reported, with each transition written by whitelisted methods (@frappe.whitelist()) so the collection app, front-desk, and analyzer bench all move samples through the same audited path. Result entry is a controller-validated form — a server-side validate hook compares each numeric result to the resolved reference range, auto-sets the abnormal/critical flag, and blocks verification of a panel until every mandatory analyte is entered. Report generation uses a Frappe Print Format (Jinja + your letterhead) rendered to PDF and released only after a two-step technologist-then-pathologist sign-off enforced by role-based permissions and a Workflow. Delivery is automated through a scheduler event in scheduler_events that emails or SMSes patients a secure report link once the report is authorized, and referral-doctor commission is accrued per reported test into a ledger you can settle against ERPNext Journal Entries.

Because this is build-to-order, nothing is a pre-packaged download. We start from your actual test menu, referral network, and report layouts, agree the scope in writing, then build and validate the app against Frappe/ERPNext v15 and v16. You get the installable source for your version, a git repository handover, and a staging UAT before anything touches production. Typical delivery is one working week from confirmed scope depending on catalog size, analyzer integrations, and the number of report templates.
