Find out root cause for increasing maintenance efforts required whether technical, functional, statutory changes or incompetence of stakeholders in handling software affecting cost and accordingly search for desired solution. It's not always technical issues, shortcomings in the software that affects which the maintenance

First question is - why? -Is this an oversight in our capacity planning process? -Did the vendor increase the cost without informing us? -Did we do a good job negotiating in the first place and discussed the increase cap? If we are at the contract renewal phase, we can attempt to negotiate the existing contract. In parallel, it makes sense to evaluate alternative solutions so then we can utilize it as leverage during negotiations (switch costs need to be taken into account). If contract negotiations is not an option, our team needs to deep dive on the cost increase and see what's driving it. Appropriate system optimizations then need to be implemented. Sometimes a larger system re-design effort will take place.

1. Check with the users about the pain points using the software, and list down the functionalities should the software have, and compare it against the proposed maintenance software. 2. Negotiate the software cost according to the scope from users. 3. Negotiate the delivery time, incase it can reduce the cost. Ensuring the highest priority functions delivered the earliest.

This is a common issue if we have a budget constraint, one thing I tried was negotiating vendor contract for ex in SAP tools or any other tool for that matter, you dont need sandbox environment, premium support, non essential modules etc. for at least maintenance purpose, point here is to rule out additional features from the vendor's contract plan which you don't require further. You should be aware that high software maintenance costs are sometimes result of these unused premium plans/features. Second, use cost effective tools & consider open source alternatives to reduce expenses, get in touch with your customer for further consultation while considering to maintain existing software functionality & security. Hope this helps :)
