Choosing Which SaaS Vendors to Keep

Choose which SaaS tools to keep by testing their jobs, required features, exports, and the steps needed to leave.

The founders of Slotline, a hypothetical booking app for small businesses, pay one vendor to collect application errors and another to alert the team when bookings fail. Both contracts renew next month. The founders want to drop one, but they first need to know whether the tool they keep can do both jobs.

For your own review, start by naming the jobs each vendor does for the app and the people who run it. That gives you something to test in a replacement and tells you which records, alerts, and accounts to take care of before you close the old service.

Name what the tool does on a difficult day

Slotline uses a host, a database, and a payment provider alongside its error tool and alert service. The last two are the first contracts the team reviews because both deal with failures. When a booking fails, the alert service contacts the person on duty, who can then use the error tool to inspect the exception.

Suppose Slotline's new host has application logs. Those logs may help an engineer understand a failed booking once someone knows to look. If the team cancels its alert service before checking how the new setup will notify the person on duty, the first sign of trouble could be a call from a customer.

Describe the jobs in terms someone can test. “Find the failed booking and the release that served it” is clearer than “provide monitoring.” “Send the urgent alert to the person on duty” names another job. Keep both on the list even if one product promises to do both.

Agree on requirements before scoring tools

Start with requirements that a tool must meet before you can consider it. If the team needs a particular data region, contract term, export format, or recovery limit, write down why and what evidence would satisfy the requirement.

Once the tools meet those requirements, compare how they fit the team. One console may be easier to search, for example, while another vendor's support hours may suit the engineer who handles overnight failures.

Record why a tool passed or failed each check. If Slotline must keep a usable copy of its error history, a tool without the required export fails that check even if its console is easy to use. The notes give teammates who missed the review enough context to see how the founders decided.

Test one replacement job with fake data

In a test app, the team can submit a fake booking and make the request fail in a known way. Give a teammate the same starting information in both tools, then ask them to find the route, time, status, release, and error output for that request. Keep a record of what they found and where they got stuck. The result tells Slotline how each tool worked for this task in its test setup.

Once the teammate can find one request, send two at the same time to see whether they can distinguish the log lines. Run the test again with a role that has limited access and check which fields that role can see.

For the alert job, trigger the test condition and have the person on duty confirm that the email or page reached them. Check whether the notice tells them enough to act and when the service would contact the backup person.

Keep the specialist when its job still matters

If the new host lets Slotline's engineer find and inspect a failed booking, the host may cover the error tool's main job. The team may still need the alert service to contact the right person on its rota and notify a backup when nobody responds. Write down which check justifies keeping the contract so the team can repeat that check when it reviews the service again.

A broad analytics product might become useful when Slotline adds a second service or when its support team needs a longer history. Record that as a reason to revisit the choice, separately from what the team needs for this renewal.

Moving more jobs to one provider may reduce the number of accounts and connections the team maintains. To understand the change in access, count the credentials, copies of data, and people who can reach them in each setup.

Plan the exit before closing the account

Once a replacement passes its checks, decide what the team needs to take out of the old tool. Slotline may need past errors for support, a copy of its settings, and a list of users with access. Open a sample export and check that someone can read the information they will need later.

If both tools can run safely together, agree on how long they will overlap and which checks the replacement must pass before you end it. During that period, track where both tools send alerts and store copies of data.

After the switch, remove the old SDKs, webhook addresses, service accounts, and keys. Check the deployed app and test environments as well as the repository, since a running copy can still send data to the old provider.

Record the renewal notice dates and deletion terms in the exit plan. Assign someone to verify that the provider closed the contract, handled retained data according to the agreement, and sent the final bill.

Put Forte through the same trial

Forte includes Service logs, request records, and metrics with hosting. Slotline can use a test Service to check the failed-booking job before deciding whether to replace a tool. See pricing and included features for the current scope.

Deploy the test booking API and trigger the same failure. Have the app emit Forte's request ID in its logs so the teammate can match the failed request with its output. Keep any remaining paging, analytics, or history requirement on the job list. Forte debugging walkthrough
