The SaaS buying checklist: cost, security and an exit plan

Write requirements as observable outcomes

A feature list is easy for a demonstration to satisfy superficially. An observable outcome is harder to misunderstand: a project owner assigns work, an external collaborator sees only their project and an administrator exports completed records.

Separate hard requirements from preferences. Missing export capability may be a deal-breaker; a less attractive dashboard usually is not. Name the person who can decide whether each requirement is met.

Include failure and administration cases. How is a user removed? Can a mistaken import be undone? Who retrieves data if the primary administrator is unavailable?

Use the same requirements for every finalist. Otherwise each demonstration becomes a different performance and the team compares impressions instead of outcomes.

Run a trial with representative work

Use synthetic or appropriately approved data. A free trial is not permission to upload all customer records before reviewing the processing terms.

Ask eventual users to perform the tasks themselves. An expert presenter can conceal friction that appears when an ordinary team member follows the same path.

Calculate the real subscription

Begin with the tier containing the required functions. Apply paid-user rules, minimum seats, usage allowances and the billing term. Include taxes, storage, automation runs, premium integrations and support where relevant.

A hypothetical $12 seat price with a five-seat minimum costs at least $60 monthly even if only three people need access. If the required administration feature is on a $20 tier, the minimum becomes $100. These are planning examples, not product quotes.

Check how temporary and inactive users are billed. Ask whether reducing seats takes effect immediately or only at renewal. Annual prepayment makes a monthly equivalent less flexible than it first appears.

Include setup and migration labour. A lower recurring price can be outweighed by time spent repairing imports or maintaining custom connections.

Review permissions and ownership

The business should control the primary account and recovery methods. Avoid leaving a former employee’s personal address as the permanent owner of an important workspace.

Check available roles and whether essential administration requires a higher tier. Someone who edits a document may not need to invite others, export all records or change billing.

Use appropriate multifactor authentication and understand account recovery. For a team, review centralized identity and offboarding requirements with the responsible person. A consumer plan may lack the necessary organization controls.

List connected applications and their scopes. Removing a person from the workspace may not automatically revoke an integration token they created elsewhere.

Understand the data relationship

Identify what the service processes and why. Read the current privacy and service terms for the exact product. If customer or employee data is involved, establish the appropriate contractual and organizational requirements before importing it.

Ask about retention, deletion, subprocessors, processing locations and support access where relevant. A general compliance statement does not replace the applicable documentation.

Review AI features separately. A familiar vendor can introduce a new processing path through an update. Check training use, retention and the controls available on your plan.

For requirements specific to the business, involve its legal or privacy adviser. The European Commission’s information is a primary starting point for individual rights, not a certification of a purchase.

Inspect security evidence by scope

When a vendor provides a report or certification, identify the covered systems, assessment period and exclusions. Evidence about one service does not automatically cover every integration or future version.

Ask how incidents are communicated and how the business obtains data during an outage. Determine whether independent copies are necessary and how to protect them.

A documented vendor cannot compensate for shared administrator passwords, abandoned access or excessive integration permissions. NIST’s small-business resources place the purchase within a wider operating routine.

Keep statements separate from evidence: a vendor claim, a behavior your team tested and a control assessed in a report are different things. Preserve that distinction in the decision record.

Test the exit while leaving is easy

Export a representative project and inspect attachments, timestamps, comments, relationships, identifiers and custom fields. Determine whether another system can use them without extensive reconstruction.

Ask how long data remains available after cancellation and whether export requires an active paid account. Check the notice period and renewal rules. Save the cancellation instructions.

Identify integrations that must be disconnected or replaced. A task tool may own a customer notification workflow; a document account may hold the only authoritative archive.

Estimate the exit in hours and responsibilities. Portability is the ability to continue the business process after the subscription ends, not simply the availability of a downloadable file.

Document and revisit the decision

Record the problem, alternatives, tested outcomes, real cost, limitations, owner and review date. Name a condition that would trigger reconsideration, such as a usage threshold or a missing future capability.

Adopt the smallest scope that has demonstrated value. Train users, transfer ownership correctly and keep a fallback during the transition. Avoid buying a large set of licenses before the first group’s workflow works.

Review before renewal and when the team or data sensitivity changes. A good purchase can become a poor fit later without either party having done anything wrong.

Use the stack guide to connect this purchase with the wider workflow, and the AI evaluation guide when generative features drive the decision.
