CUSTOM SOFTWARE PROCUREMENT
Evaluating Software Vendors: The 7-Point Scorecard
Bottom Line Up Front (BLUF)
Most businesses evaluate software vendors by comparing feature lists and pricing tiers. This approach fails when the system handles sensitive operational or client data. The correct evaluation framework scores vendors on 7 weighted criteria: data sovereignty, integration depth, compliance posture, escape clause, reference quality, deployment timeline, and total cost of ownership. Any vendor scoring below 3 on the first three criteria is automatically disqualified. Based on 20 vendor evaluations we have conducted for Houston firms since 2024.
Choosing the wrong software vendor does not just waste money. It creates operational exposure. If a vendor stores your data on shared infrastructure without proper encryption, or if their system goes down during a critical deadline, the consequences fall entirely on your business. The vendor walks away. You do not. This scorecard gives you the structured evaluation process to avoid that outcome.
The 7-Point Vendor Scorecard
Rate each vendor on a 1-5 scale for each criterion. Weight the scores as indicated. Any vendor scoring below 3 on criteria 1 through 3 is automatically disqualified regardless of price or feature set.
Data Sovereignty (Weight: Critical)
Where is your data stored? Who has access? Is it encrypted at rest AND in transit? Can data be exported in a standard format (CSV, JSON) at any time without vendor assistance? A vendor that cannot answer these questions in writing within 48 hours of request is a liability. Ask specifically: does data leave the United States at any point during processing or backup? For Houston energy and medical firms subject to PHMSA or HIPAA, this is not negotiable.
Integration Depth (Weight: Critical)
Does the system integrate with your existing tools via documented API? Or does it require manual data transfer through CSV uploads and copy-paste workflows? Ask for the API documentation before you sign anything. If the vendor says the API is coming in a future release, treat it as nonexistent. A system that cannot talk to your other systems creates data silos that cost you 10-20 hours per week in manual workarounds. We have seen this pattern in our technical debt audits across Houston firms.
Compliance Posture (Weight: Critical)
Is the vendor SOC2 Type II certified? Do they maintain a BAA (Business Associate Agreement) for HIPAA-adjacent work? Can they provide their most recent penetration test report? These are not optional requirements for regulated industries. They are minimum table stakes. If a vendor cannot produce these documents, they have not invested in the infrastructure to protect your data.
Escape Clause (Weight: High)
What happens when you want to leave? Is your data held hostage in a proprietary format? The best vendors guarantee full data export within 30 days of termination notice in a standard format you can import elsewhere. If the contract does not include this clause, add it. If the vendor refuses, that tells you how they expect to retain customers, not through product quality but through switching costs.
Reference Quality (Weight: High)
Ask for 3 references from companies of similar size and industry. Call them. Do not email. Ask specifically: What broke? How fast did they fix it? Would you choose them again? What surprised you about the implementation? Vendors will give you their best references, so even those should be scrutinized. If a reference hesitates when you ask about reliability, that is your answer.
Deployment Timeline (Weight: Medium)
Enterprise vendors routinely quote 6-12 month implementations with extensive customization phases and change order fees. A focused custom build should deploy an MVP in 4-8 weeks. Any timeline over 12 weeks for an initial deployment is a red flag that either the product requires excessive configuration or the vendor is padding the engagement. Compare these timelines to our Houston pricing benchmarks for realistic expectations.
Total Cost of Ownership (Weight: Medium)
Calculate the 3-year TCO including licenses, implementation fees, training, annual price increases (check the contract for escalation clauses), and ongoing support costs. SaaS per-seat costs compound aggressively as your team grows. Compare against a custom build amortized over the same period. Our Build vs Buy framework provides the calculation methodology.
The Scoring Matrix
| Criterion | Vendor A | Vendor B | Custom Build |
|---|---|---|---|
| Data Sovereignty (Critical) | ___/5 | ___/5 | 5/5 (you own it) |
| Integration Depth (Critical) | ___/5 | ___/5 | 5/5 (built to spec) |
| Compliance Posture (Critical) | ___/5 | ___/5 | Depends on hosting |
| Escape Clause | ___/5 | ___/5 | 5/5 (you own the code) |
| Reference Quality | ___/5 | ___/5 | Check agency portfolio |
| Deploy Timeline | ___/5 | ___/5 | 4-8 weeks typical |
| 3-Year TCO | $___ | $___ | Calculate with our guide |
Red Flags from 20 Houston Vendor Evaluations
Across 20 vendor evaluations we have conducted for Houston businesses since 2024, these patterns appeared repeatedly:
- No written DPA (Data Processing Agreement): 35% of vendors could not produce a DPA within 48 hours. If they do not have one ready, they have not thought through data handling.
- Vague API documentation: 40% of vendors marketed API integrations that, upon inspection, were limited to read-only access or required expensive premium tiers to unlock write capabilities.
- Hidden price escalation: 25% of contracts contained annual price increase clauses of 5-15% buried in the terms. A $50 per user per month tool becomes $65 per user by year 3.
- No exit provision: 30% of contracts had no explicit data export clause, meaning your data could be effectively held hostage if you decide to switch vendors.
- Demo-only features: 20% of features shown in sales demos were actually upcoming roadmap items, not production features. Always ask to see the live product, not slides.
When to Skip Vendor Evaluation Entirely
The vendor evaluation process assumes you are buying off-the-shelf software. But in many cases, the right answer is to build custom instead. If your workflow is unique enough that every vendor requires extensive customization, you are paying enterprise SaaS prices for a bespoke solution without owning the result. At that point, a custom build gives you full ownership, full control, and often lower total cost. Use our SaaS vs Custom Decision Framework to determine which path applies to your situation.
