Contact center vendor selection and CCaaS RFP consulting
Like a home inspector, but for contact center software
Know what you're buying before you sign
Tech Stack Advising is a CCaaS RFP consultant that runs contact center vendor selection from requirements through signed contract, so you can choose the right contact center platform, whether you're weighing Genesys vs NICE vs Five9 or picking an AI vendor. We've guided over $100 million in CCaaS and AI technology transactions and have insiders at every major vendor. We do the legwork, make vendors demo your real use cases, expose each product's limitations before you buy, and use our combined buying power to negotiate the best price and the right products, typically in half the time of a self-run evaluation. And we don't make a recommendation and walk away: we bid on the implementation and ongoing support, so we own the success of what we recommend.
- Did the demo look perfect, then implementation revealed the piece you didn't buy?
- Facing a six-month evaluation your team doesn't have time to run?
Vendor Evaluation and Selection
Why companies trust us to run their vendor selection
- Over $100 million in contact center technology transactions guided.
- Insiders at every major vendor, so we know the real limitations behind the demo.
- Half the time. We streamline the process and do the legwork so your team doesn't have to.
- More leverage. Our combined buying power gets better pricing and the right products in the contract.

Vendor Evaluation and Selection services we provide
Every platform has strengths and trade-offs. We know these products deeply, so we walk you through both and nothing surprises you after you buy.
Requirements and use case definition
We document how your contact center actually works so every vendor is measured against your needs, not their pitch.
Custom, use-case-driven demos
We hold vendors to scripted demos built on your real scenarios, not the generic tour every prospect sees.
The limitations report
Our insiders and implementation experience tell you what each platform is bad at, so you aren't surprised after go-live.
Bill of materials verification
We check that every feature you were demoed is in the quote, ending the accidental bait and switch of "you didn't buy that piece."
Contract and pricing negotiation
Our buying power across clients gives us leverage most companies don't have alone, for better pricing and terms.
Streamlined, end-to-end process
We run the timeline, vendor communication, and scoring so a six-month evaluation takes about half the time.
Projects are typically staffed within 24 hours.

Vendor Evaluation and Selection FAQs
What does a contact center vendor selection consultant do?
We run the evaluation for you: define requirements, shortlist vendors, script custom demos, uncover each product's limitations, verify the quote matches what was demoed, and negotiate the contract.
Genesys vs NICE vs Five9: which contact center platform is best?
There is no single best platform. Five9 is strongest for outbound-heavy and Salesforce-centric teams, Genesys Cloud for large, complex omnichannel operations, and NiCE CXone for enterprises focused on workforce management and quality. The right choice depends on your size, channels, CRM, and AI plans, which is exactly what our evaluation measures.
Do you run contact center RFPs?
Yes. We write the requirements, build the RFP around your real use cases, manage vendor responses and scripted demos, score each vendor, and negotiate the final contract.
How much time does working with Tech Stack Advising save?
A typical self-run CCaaS evaluation takes around six months. Because we streamline the process and do the legwork, our clients typically finish in about half that time.
How do you prevent surprises during implementation?
The most common problem is buying from a demo, then learning during implementation that a demoed feature wasn't purchased. We verify the bill of materials against your use cases before you sign, so the accidental bait and switch doesn't happen.
Can you really get a better price than we could on our own?
Yes. Our clients and our firm together represent significant buying power with contact center vendors, which gives us leverage on pricing, terms, and included products that a single buyer rarely has.
Do you stay involved after the vendor is selected?
Yes. We don't make a recommendation and say goodbye. We bid on the implementation and ongoing support, so we own the success of what we recommend. An advisor who doesn't own the implementation is just a salesperson. We're your partner at vendor selection, implementation, and beyond.
