TESSA · The PBES service advantage

Medical Equipment Asset Management Built Into Biomedical Service

PBES does more than inspect and repair equipment. Through TESSA — Technical Equipment Support and Service Assistant — PBES helps customers organize equipment records, service history, PM documentation, repair follow-up, and asset visibility.

  • Full equipment inventory by location
  • Service history, PM, and repair follow-up
  • Customer dashboards where applicable
  • Multi-site rollups for administrators

The problem

Most facilities don't have a real view of their equipment.

Equipment records tend to live in binders, spreadsheets, technician notes, and email threads. When a surveyor asks — or a device disappears between locations, or a battery expires quietly — the answer is usually 'let me check.'

For multi-site organizations, this only gets harder. Consistent records across every site, standardized PM intervals, and centralized visibility for administrators are hard to build after the fact.

PBES built TESSA because service and records belong on the same platform. When a technician documents a visit, the asset record updates. When PM comes due, administrators can see it. When repairs happen, follow-ups don't drop.

What TESSA helps track

What TESSA gives you visibility into.

TESSA is designed around how biomedical service actually works in real facilities.

Equipment inventory

Every device tracked by make, model, serial, and location.

Service history

Every visit, every finding, and every action captured on the record.

PM schedules & status

Interval, last-service, and next-due visibility per device.

ESI records

Electrical safety inspection results on the same asset record.

Repair follow-up

Open findings routed to closure — nothing drops between visits.

Customer dashboards

Where applicable, a facility-facing view of equipment and status.

Multi-site rollups

Administrators see equipment and status across every location.

Change history

Ownership, location, and configuration changes retained over time.

Lifecycle insights

Age, cycle count, and repair history to support replacement decisions.

Our approach

How PBES handles every service visit.

A disciplined sequence, delivered the same way on every device — so your team gets consistent service and consistent documentation through TESSA.

  1. Step 01

    Document the reported issue

    Capture symptoms, error codes, history, and how the problem is affecting the workflow.

  2. Step 02

    Identify equipment and asset details

    Confirm make, model, serial, and control number so the record ties back to the right device.

  3. Step 03

    Inspect and test the device

    Visual inspection plus operational testing appropriate for the equipment and reported issue.

  4. Step 04

    Troubleshoot the likely cause

    Based on manufacturer guidance and service findings, isolate the probable cause or next step.

  5. Step 05

    Perform service, PM, or recommendation

    Adjustments, cleaning, wear-part replacement, or clear repair recommendations when parts and scope allow.

  6. Step 06

    Verify operation and document in TESSA

    Post-service verification and a clean written report you can hand to an administrator or surveyor.

TESSA · The PBES advantage

Why TESSA is different — it's built for how service actually happens.

TESSA isn't a standalone database. It's connected to actual field service work. When PBES techs work on a device, TESSA is the record — not something an administrator has to update after the fact.

TESSA — Technical Equipment Support and Service Assistant — is how PBES organizes equipment records, service history, PM status, and repair follow-up for the facilities we serve.

  • Service and records on the same platform
  • Customer dashboards where applicable
  • Multi-site rollups for administrators
  • Change history retained over time
  • Follow-ups don't drop between visits
  • Capital planning support with lifecycle context

Documentation

Clear documentation after every service visit.

TESSA helps PBES produce clean, consistent service documentation — the record your administrators, biomed program, and surveyors expect to see.

  • Full equipment inventory across sites
  • Per-device service history
  • PM schedule, last-service, next-due
  • ESI records on the same asset
  • Repair status and open follow-ups
  • Photos and technician notes
  • Location and ownership change history
  • Custom reports for administrators

FAQ

Frequently asked questions.

Is TESSA a standalone software product?

TESSA is built into how PBES delivers biomedical service. It gives customers organized equipment records, service history, and status — as part of the PBES service relationship.

Can we get a customer dashboard for our facility?

Where applicable, PBES can provide customer dashboards showing equipment status, service history, and open items. Scope depends on the service relationship.

Does TESSA replace our compliance program?

No. TESSA gives you organized records to support your program. Compliance decisions remain the facility's responsibility.

Does TESSA support multiple sites?

Yes. TESSA is designed for multi-site organizations, with rollups that let administrators see equipment and status across every location.

What kinds of equipment can TESSA track?

Patient-care and clinical devices PBES services can be captured on the asset record. Scope depends on the equipment and the service relationship.

How is TESSA different from a spreadsheet?

TESSA is connected to actual service work. When PBES techs work on a device, the record updates — not something an administrator has to reconcile after the fact.

Can TESSA help with capital planning?

Yes. Lifecycle context — age, cycle history, repair frequency — helps administrators plan for replacements before equipment fails.
