LIS Support SLA Checklist: Questions to Ask Vendors

By Dr.Lably Team · 8 min · Published 2026-05-07 · Updated 2026-10-01

How to judge an LIS vendor's support before you sign: severity levels, response vs resolution times, scenario questions to ask, how to test support, and what to put in the contract.

Key takeaways

  • A support SLA is only meaningful if it defines severity levels and separates response time from resolution time.
  • Ask scenario questions ('reports won't print at 8 am on a Sunday') instead of 'do you have good support?'
  • Test support before you sign: call and message the support line yourself during peak hours.
  • Put the support hours, channels, and response commitments in the contract, not just the sales deck.

Why support matters more for labs than most software

A lab cannot pause. If registration, result entry, or report release stops for an hour on a busy morning, patients wait, doctors call, and reports go out late. The software's support model decides how long that hour lasts, so it deserves as much attention as features or price.

Severity levels: what a clear SLA looks like

Ask every vendor to show their severity levels in writing. If they cannot, the SLA is a promise, not a commitment. A clear structure looks something like the table below; the exact times are what you negotiate.

SeverityExampleWhat to ask for
CriticalSystem down, or reports cannot be releasedResponse within minutes, continuous work until restored
HighOne module failing, such as billing or WhatsApp deliveryResponse within an hour, fix or workaround the same day
MediumA template or calculation needs correctingResponse the same day, fix within a few days
LowQuestions, training, feature requestsResponse within one or two working days

Response time vs resolution time

Response time is how quickly a person acknowledges your issue. Resolution time is how quickly it is actually fixed or worked around. A vendor promising a 10-minute response with no resolution commitment can still leave you stuck for a day. Ask for both, at least for critical and high severity.

Scenario questions to ask before you sign

Scenario questions reveal how support really works. Ask each vendor to walk you through exactly what happens in these situations.

  • Reports won't print or send at 8 am on a Sunday. Who answers, and on which channel?
  • An analyzer stops sending results mid-morning. Who diagnoses it, you or the analyzer vendor?
  • A report was released with a wrong reference range. How fast can the template be corrected and the report reissued?
  • Our internet is down. Can staff keep registering patients, and what happens when it returns?
  • We need a new test added today. Can we do it ourselves, or must we raise a ticket?

Test support before you commit

During the trial, contact support yourself on every channel they list, at least once during your peak morning hours. Note how long each reply takes and whether the answer actually solves the question. Ask two or three existing customers of a similar size how support performed during their own go-live.

What to put in the contract

Sales promises are easy to forget. Make sure the agreement or order form states these points clearly.

  • Support hours and days, including Sundays and holidays if your lab is open
  • Support channels (phone, WhatsApp, email, ticket) and the escalation contact
  • Response and resolution commitments by severity
  • Whether onboarding, training, and template changes are included or charged
  • How you can export all your data if you leave

Frequently asked questions

What is a good support response time for lab software?

For critical issues that stop reporting, look for a response in minutes rather than hours, and continuous work until service is restored. For routine questions, a same-day or next-day response is usually enough.

Is WhatsApp support good enough for a lab?

WhatsApp is fast and convenient for everyday questions, but for critical issues you also want a phone line and a named escalation contact, with the commitments written into the agreement.

Should support be included in the subscription price?

Ask directly. Some vendors include support, training, and template changes; others charge separately. Compare vendors on total first-year cost including support.
