I spent close to a decade on the vendor side of ERP implementations. I wrote proposals. I presented them. I watched experienced sales teams shape language deliberately to win deals at prices clients did not fully understand they were agreeing to.
I am not writing this to attack vendors. The people building those proposals are doing their job, competing in a market where every competitor is using the same techniques. The problem is not that vendors are dishonest. The problem is that buyers do not know how the document in front of them was actually constructed.
Here is what I learned from the inside.
Most ERP proposals are written to do two things at the same time. They make the vendor look like the obvious choice. And they protect the vendor from being held accountable to anything they cannot guarantee. Both of those goals are completely reasonable from the vendor's perspective. But they create predictable patterns in the document that a careful reader can recognise and respond to.
There are five places where the gap between what a proposal sounds like and what it actually commits to tends to live.
The first is scope language.
Watch for phrases like "supports key processes" or "configures core functionality" or "covers standard requirements." These phrases sound concrete but they are not. Standard according to whom? Core in what definition? Key as defined by which document? The proposal that says "implement the inventory module" is fundamentally different from the proposal that says "configure the inventory module to support the 23 specific business rules documented in the requirements specification dated October 2024." The first commits to nothing measurable. The second commits to an inspectable scope.
Ask the vendor to show you the document that defines what scope actually means in their proposal. If that document does not exist, the scope is whatever they say it is when delivery time comes.
The second is pricing structure.
Most proposals separate license costs from implementation services. That separation is normal and reasonable. But it also means that the implementation services line item — usually shown as a fixed estimate — is not a fixed price. It is an estimate based on assumptions. Those assumptions are written somewhere in the proposal but rarely highlighted.
Look for the assumptions section. If it says things like "assumes data is in a clean and migration-ready state" or "assumes the client provides a dedicated project resource" or "assumes business processes are documented prior to project start" — every one of those assumptions is a future change order if it turns out not to be true. And in most mid-market businesses several of those assumptions will not be true.
Ask the vendor what happens to the price if the assumptions do not hold. Get the answer in writing.
The third is the difference between commitment and capability.
A proposal that says "the system supports multi-currency reporting" is telling you what the software can technically do. It is not telling you that multi-currency reporting will work for your specific business out of the box. The capability exists. The commitment to make it work in your environment is a different conversation.
Read every claim about what the system does and ask one question. Is this something the vendor is committing to deliver in my environment, or something the software is theoretically capable of? If it is the second, you need a separate conversation about what it would take to make it actually work for you.
The fourth is timeline language.
Proposals routinely show timelines that assume everything goes well. No data quality issues. No scope debates. No competing priorities. No key person unavailability. No integration surprises. The timeline you see is the best case, not the realistic case.
Ask the vendor for two timelines. The proposed timeline and the realistic timeline including typical risk events. The gap between those two answers will tell you a lot about how transparent the vendor is willing to be.
The fifth is resource assumptions.
Almost every implementation proposal assumes the client will provide significant internal resources. Subject matter experts. Decision-makers. Project sponsors. Data owners. Testing volunteers. The proposal usually mentions these assumptions briefly but does not quantify them. The result is that clients sign proposals without realizing they have just committed hundreds of hours of their own people's time.
Ask the vendor to estimate how many hours of client team involvement the project requires by role. Compare that to what your business can actually deliver while still running. If those two numbers do not match, the project cannot succeed as written regardless of what the vendor delivers.
Here is the broader point.
A vendor proposal is not a description of what you will receive. It is a negotiating position. The vendor expects you to push back. They have priced in room to negotiate, room to add scope through change orders, and room to renegotiate timelines once the project is underway.
When you read a proposal like a buyer instead of a prospect, you are not being adversarial. You are doing exactly what the vendor's own team would do if they were the ones evaluating it. They would ask hard questions. They would push for specificity. They would refuse to accept aspirational language as commitment.
You should do the same. The proposal in front of you is not a contract until you have made it one.
If you found this useful and you are evaluating an ERP system, the most important thing you can do before signing anything is have someone read the proposal who is not financially incentivised by the outcome. That is exactly what Metadata Advisory exists to do.
