Work through the list in order: scope first, response second, price and contract last. Many MSMEs compare per-endpoint prices of services that do completely different things: one only forwards alerts by email, another isolates an infected laptop at 3 a.m.

How to use it. Send the scope items to every shortlisted provider as part of your request for proposal and ask them to answer in writing. Tick an item only when you have the answer in the proposal or contract, not when a salesperson said it on a call. Items you cannot tick become negotiation points or reasons to drop a provider.

Worked example. A 60-person firm sends the checklist to three providers. One cannot confirm 180-day log retention without a higher tier; another excludes Microsoft 365 logs. Normalising scope changes which quote is cheapest.

Limits. The checklist is general. Regulated entities (banks, NBFCs, market intermediaries, insurers) have their own requirements from RBI, SEBI or IRDAI. See the best-fit method and SLA and contract questions.
