The maintenance cost of LIMS laboratory information management system has always been a factor that cannot be ignored. The maintenance workload of commercial LIMS software with high maturity and configuration realization is less, especially the system maintained by users can greatly reduce the maintenance cost. Therefore, when purchasing the system, we need to consider whether the system can be maintained independently and whether it is not necessary to rely too much on suppliers (which is a good thing for us educated youths). At the same time, the company should give priority to the configurable (configurable) system; After the business changes, business department personnel can modify the system in time to meet the needs of the business. Of course, after the system passes the final inspection, it also needs the supplier to provide fault treatment measures, emergency treatment plans and after-sales service plans.
