A guide to selecting custom software development companies for your MVP
By Gabriel CA · Kraftwire Software
Review your product scope and compile a structured evaluation checklist for candidate agencies. Record engineering workflows, testing regimes, and deployment pipelines across candidate proposals. Compare each team against your agreed delivery criteria, inspect code ownership clauses, and decide whether their operational practices match your milestones.
Inspect vendor technical proposals against your operational requirements, testing expectations, and IP ownership criteria. Record specific architectural commitments, repository rights, test automation evidence, and milestone deliverables across candidate submissions. Choose which development partners meet your architectural and governance standards by applying a structured vendor evaluation framework.
How should you inspect code ownership and repository governance?
Inspect the candidate master services agreement and statement of work for explicit intellectual property assignment and repository access clauses. Record the presence of terms granting administrative repository control, copyright assignment upon milestone settlement, and unencumbered dependency licensing across all proprietary modules. Decide whether the candidate firm supports full autonomy by confirming unrestricted access to source control repositories throughout the development lifecycle, or eliminate vendors requiring proprietary hosting lock in.
Review the proposed code management model by examining how the vendor structures branches, pull requests, automated linting checks, and merge approvals during active sprints. Record the proposed repository hosting platform, branch protection configurations, automated build status visibility, and peer review signoff requirements. Choose vendors that provide direct trunk or branch visibility in standard version control systems, or require revisions to project onboarding terms before contracting.
Examine vendor policies regarding third party open source libraries, package management practices, and commercial framework licensing dependencies. Note all documented third party dependencies, open source license classifications, and recurring runtime subscription costs disclosed in vendor cost schedules. Agree on explicit license boundaries for all third party components before contract execution, or reject proposals containing incompatible copyleft or restrictive commercial libraries.
How should you compare technical architecture and system design?
Inspect the architectural blueprint proposed by each candidate firm, focusing on modular layer separation, database schema definitions, and interface boundaries. Record the proposed database layer, backend service framework, client side rendering approach, and inter service communication protocols outlined in the technical bid. Decide whether the vendor architectural proposal satisfies your target throughput and modularity requirements, or request a revised system design before approving development sprints.
Review candidate proposals for runtime infrastructure provisioning, containerization strategies, and hosting platform configurations. Note whether infrastructure is defined as code, the specific hosting environments specified, and the administrative account ownership model for staging and production servers. Choose between vendors using industry standard deployment platforms and those proposing custom hosting arrangements that could impede operational handovers.
Compare vendor interface documentation practices, schema definition standards, and validation mechanisms for external system communication. Record the presence of interface documentation formats, contract validation suites, error response standardization, and schema migration strategies. Agree on API boundary definitions and interface contracts to verify that system integration points remain maintainable across future releases.
How should you review quality assurance and testing pipelines?
Inspect candidate continuous integration pipelines for automated linting, unit testing, integration verification, and staging deployment automations. Record the automated checks executed on every pull request, target code coverage conventions, and automated build failure notification protocols. Decide whether the candidate agency demonstrates rigorous verification practices, or mandate automated testing thresholds in your development agreement.
Review candidate staging deployment workflows, database seeding routines, and test data management practices used during sprint verification. Note whether staging environments reflect production architecture, how synthetic test data is generated, and how environment variables are secured. Choose development teams that provide isolated staging environments matching production runtime conditions, or decline proposals relying entirely on local developer testing.
Examine proposed bug classification matrices, defect remediation turnaround times, and user acceptance testing criteria across vendor proposals. Record the agreed defect severity levels, resolution windows for high priority bugs, and warranty remediation timelines post release. Agree on formal acceptance testing windows for every sprint delivery to prevent regression creep and unspecified defect ownership.
How should you review team allocation and communication cadence?
Review candidate staffing schedules, full time equivalent allocations, and engineer seniorities assigned to your project scope. Record named engineering leads, dedicated frontend and backend roles, shared quality assurance staffing, and planned resource replacement protocols. Decide whether vendor team allocation matches your delivery tempo, or reject models where core engineers are split across numerous unrelated accounts.
Inspect the communication hierarchy, daily standup participation options, and direct messaging channels proposed by candidate firms. Record proposed collaboration platforms, time zone overlaps with your team, scheduled demonstration cadences, and written progress reporting formats. Choose agencies that provide clear escalation pathways and direct communication with practicing engineers rather than layering multiple non technical intermediaries.
Compare how candidate firms handle mid sprint scope modifications, estimation updates, and prioritization adjustments in their project management systems. Note the formal change request process, estimation variance policies, and sprint review approval workflows documented by each agency. Agree on sprint duration, backlog grooming mechanisms, and scope adjustment policies to accommodate evolving product feedback without contract disputes.
How should you prepare commercial models and milestone verification?
Inspect the payment schedule and milestone verification criteria across all candidate statements of work. Record the exact conditions required for milestone payment authorization, such as functioning test builds, deployment to staging, or passing test suites. Decide whether financial milestones correspond strictly to demonstrated, deployed software increments rather than arbitrary calendar passage.
Compare pricing structures, hourly rate cards for out of scope work, and budget variance caps across candidate proposals. Record whether proposals specify fixed price deliverables, blended hourly billing, dedicated sprint retainers, or hybrid payment mechanisms. Choose fixed scope or time and materials engagement models based on the maturity of your functional requirements and volatility of market validation goals.
Review vendor contract terms regarding post launch bug fixing, service level commitments, and ongoing platform maintenance support options. Note the duration of the complimentary defect warranty window, support response times for production outages, and hourly rates for post warranty support. Agree on explicit warranty periods covering post deployment defect remediation at vendor expense before signing initial agreements.
How should you document knowledge transfer and production offboarding?
Inspect vendor handover checklists, infrastructure runbooks, and developer onboarding documentation delivered at project conclusion. Record the presence of environment provisioning scripts, local development setup guides, architectural data flow diagrams, and administrative credential rosters. Decide whether vendor transition documentation is sufficient for internal handoff, or mandate recorded architectural walkthroughs and deployment runbooks.
Review candidate offboarding workflows for revoking developer access, rotating production API keys, and transferring cloud hosting root accounts. Note the schedule for key rotation, cloud billing account reassignment, third party service credential handovers, and database access termination. Choose development partners that implement secure secret management and infrastructure access revocation procedures during handoff.
Compare vendor recommendations for production application performance monitoring, error tracking instrumentation, and log aggregation pipelines. Record the recommended monitoring tooling, uptime alerting configurations, log retention policies, and incident escalation protocols for live operations. Agree on ongoing operational monitoring requirements to preserve system availability once the vendor development phase concludes.
FAQ
How Should You Inspect Candidate Agency Portfolios?
Review candidate case studies and verify code ownership models, architectural patterns, and testing documentation against your defined product milestone.
