The short answer
A lab runs two operations: clinical work (collecting, testing, reporting) and the business (reagents, equipment, billing, staff, the books). Your laboratory information system (LIS) or EMR handles the first, an ERP the second. Connected, a test ordered in one becomes a charge, stock movement and revenue line in the other, typed once. Prometheus, our ERP built on ERPNext, has a healthcare and laboratory edition for this.
ERP, LIS and EMR: who does what
| Area | Usually in the LIS or EMR | Usually in the ERP |
|---|---|---|
| Orders, specimens, results, reports | Yes | Receives what billing and stock need |
| Instrument interfaces and result validation | Yes | No |
| Reagents, consumables, controls by lot and expiry | Sometimes | Yes |
| Purchasing and supplier management | No | Yes |
| Billing patients, insurers and other payers | Sometimes | Yes, with accounting |
| Equipment, maintenance and calibration | Sometimes | Yes, as assets and maintenance schedules |
| Staff records, credentials and scheduling | No | Yes |
| Accounting, budgets and management reporting | No | Yes |
Where a provincially certified EMR is required, Prometheus runs alongside it and does not replace it.
Smaller centres
Smaller centres sometimes also run patient registration, appointments and consultations in Prometheus: the healthcare edition can manage patient details, appointments, encounters, assessments and medical coding.
What an ERP should do for a lab
Reagents by lot and expiry
Tracked by batch in every location, with reorder minimums per site.
Receiving checks
A quality inspection (arrival temperature, certificate of analysis) before stock is usable.
Tests that drive billing
Each test or panel priced per payer; billed tests consume reagents for costing.
Equipment as assets
Analyzers, centrifuges, refrigerators: maintenance, calibration, service history, depreciation.
Staff and credentials
Qualifications, renewal dates, schedules and training, with reminders before anything lapses.
Finance that closes cleanly
Revenue by test, payer and site, cost per test, budgets, month-end: one ledger.
More detail
- Lot tracking lets you issue the right lot, see what expires next month and trace which lot was in use on a given day.
- Collection sites and the main laboratory each have their own minimums, with purchase requests raised automatically.
- Payers include patients, private insurers, employers, other laboratories and institutional clients; pricing rules keep contract rates straight.
- Staff qualifications, schedules and training sit in the HR module.

Privacy and access in a Canadian context
Labs hold personal health information. Depending on province and type of organization, a provincial health information law such as Ontario's PHIPA may apply, and PIPEDA for commercial activities. For the ERP:
Only what it needs
Billing needs a patient reference and the tests performed, not full results.
Role-based access
Finance, purchasing and front desk see different things: ERPNext role permissions, tested by role.
Audit trails
Who changed sensitive records, and who viewed them where your policies require it.
Hosting location
Decide where system and backups live; Canadian regions support residency, not every obligation.
General information, not legal advice: your privacy officer or legal adviser should confirm what applies to you.
What usually goes wrong
| Mistake | Why it matters |
|---|---|
| Making the ERP the LIS | Validation and instrument interfaces need a system designed (and where required approved) for them |
| Tests not linked to stock | Stock and cost per test drift apart |
| Payer rules in people's heads | Billing depends on who is on shift |
| Integration left until last | The LIS or EMR link shapes the design; we connect by REST API, file exchange or HL7 where supported |
- We know the source of truth for patients, orders and results.
- Reagents and consumables are tracked by lot and expiry in every location.
- Each test has a price per payer, and contract rates are recorded.
- Billed tests are linked to the reagents and consumables they use.
- Equipment has maintenance and calibration schedules on record.
- Roles and permissions are defined for finance, purchasing, front desk and management.
- Hosting location, backups and audit trails are agreed with our privacy officer.
Prometheus in practice
Examples of Prometheus deployments for diagnostics and laboratory organizations are available on request. For Canadian labs and clinics, the edition is configured for:
- Provincial sales taxes where they apply
- English and French interfaces
- Canadian hosting options
- Your provincial privacy requirements
When to bring in help
A small clinic with simple billing can often use accounting software and a well-run LIS. Bring in an ERP partner for several sites, many payers or contract rates, unclear reagent costs, or a clinical-to-business integration. With Promatics, one team configures, integrates, migrates, trains and supports you afterwards.
