A Practitioner's Point of View
What a decade of B2B replatforming has actually taught me about picking the right platform, and the small set of decisions that separate the projects that land from the ones that quietly stall in year two.
"Take the RFP seriously. Not because of the vendors. Because of you."
The RFP isn't a vendor exercise. It's the first time the business actually has to agree on what it needs. The clarity it forces is worth more than any answer a vendor will give you back.
Map order-to-cash first
Before you talk to a single vendor, walk through how an order actually moves through your business today. Most teams skip this, and pay for it later.
Beware the demo gap
Ask 'Is it live now?', not 'Can it do this?' Roadmap features are not the same product you'll deploy in nine months.
Buy for year three
Solve for the workflows you'll have in three years, not just the ones you have today. The cost of getting this wrong is a second replatform.
