Buying a SaaS replacement with acceptance and migration terms
Short answer
Buy a SaaS replacement with the switchover day settled: who moves the open cases, on which work the team accepts the application and what happens if work cannot start. These agreements shape the scope of the order as much as the program's screens do.

An employee must be able to carry on with a case the day after the switch, so acceptance also covers cases moved from the old system. Exporting an application, for example from Power Apps, moves the configuration, but the data and the history need a separate plan.
- A list of open cases and the person who moves them
- Acceptance on the team's real cases
- A condition for going back to the old system
- Access to the old system during the transition
An employee must be able to carry on with a case
Suppose a company replaces its system for internal orders. The new application creates an order from scratch correctly. On the day of the switch, though, some orders already have an agreed scope and are waiting for delivery. The employee needs to find the earlier agreement and record what happens next without collecting the information again.
The offer should make clear whether such cases will be moved or finished in the current tool. If they are to go into the new application, the team should be able to assess a sample continuation before go-live. A demo of creating a new order does not cover this situation.
The company's part in preparing the data also matters. The contractor can move the agreed scope, but someone on the client's side has to explain unclear labels or name the person responsible. Name these tasks and put them in the plan. Otherwise the date rests on the assumption that the data is ready, although nobody has confirmed it yet.
Acceptance should concern the work you are buying
Useful acceptance criteria can be written in the users' language. The person taking over an order finds it, understands the current agreement and takes the next step needed. The manager sees the state of the case, and the administrator can grant the required access. That is a starting point for agreeing the scope the contractor must show on the right data and roles.
Separate what is needed for go-live from changes that can be made later. The company should know who decides on the start and how unresolved problems will be described.
Judge an offer for a ready product or an integration the same way. A supplier may have a migration and rollout service that meets the company's needs. Compare the scope of the switch, the team's duties and the help afterwards.
Settle what will really be handed over
The application file is one part of the handover. Microsoft describes Power Apps canvas app packages as basic import and export, and points to solutions as the recommended way to manage the life cycle. So when you buy, also settle the environment, the connections needed and responsibility for go-live.
A custom solution needs agreed access to the code, the data and the documentation. An export should keep the links needed to recreate the work, also if you change contractor later. The buyer should understand which external services will still be needed and who will manage them.
The switchover plan should also describe the case where go-live is postponed. The team has to know where it works until then and what happens to changes made after the migration was prepared. Whether you can keep using the old tool depends on the terms agreed with its supplier.
After the start you need a person who takes reports and a way to clarify missing or conflicting data. Settle what help at go-live covers and what will be part of later maintenance. Then the offer also describes the first weeks of work.
Talk to Syntalith about one open case and the planned date of the change. We can discuss the proposed handover scope, the team's part and how readiness for work is judged. A custom application or automation at Syntalith costs from €3,000 net (pricing).

The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 3,000 input tokens and 300 output tokens per call at Anthropic's rates, at the ECB rate of 1.1205 USD per euro on 22 October 2026.
- The time from receiving a case to the result, before and after the change
- Cases the application passed to a person
- Corrections by the person checking
- The cost of the model and maintenance at the target volume

Payback: 0.8 mo.
5 minutes to read an email and reply and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: Claude Sonnet 5.5, about 3,000 + 600 tokens per message with a draft reply, at the ECB rate of 1.1205 USD per euro on 22 October 2026.
