Custom Enterprise Software Development Services

Cost depends on scope, integrations, compliance requirements, and team size. A focused MVP with one core module and essential integrations typically starts at $50,000–$100,000 and takes 2–4 months. Mid-complexity platforms with multiple modules, third-party integrations, and role-based access run $100,000–$300,000. Full enterprise applications with multi-tenant architecture, advanced analytics, AI/ML integration, and compliance certifications can exceed $500,000.

We offer dedicated team and time-and-materials engagement models. Every project starts with a scoped proposal so you know exactly what you're paying for before development begins.

A proof of concept is ready within 2 weeks. An MVP with core functionality typically takes 1–3 months. A mid-complexity enterprise platform with multiple modules, integrations, and compliance takes 4–8 months. Full-scale platforms with multi-tenant architecture, enterprise mobility, and advanced analytics take 6–12+ months for the initial release, with ongoing development after that.

We use agile development and deliver working modules early so your team can start using features while we continue building.

Yes. Legacy system modernization is one of our core services. We start with a technical assessment of your current architecture, identifying what to preserve, what to re-engineer, and what to replace. Migration is phased: we run old and new systems in parallel, validate data integrity at every step, and cut over with minimal downtime.

We've migrated monolithic Ruby on Rails systems to Golang microservices for DispatchHealth, rebuilt integration frameworks for Uniform, and transformed single-host architectures into multi-tenant platforms for JLL. We carefully preserve business logic and data while moving you to modern, scalable infrastructure.

Yes. We build API-driven integrations with ERP systems (SAP, Oracle, Microsoft Dynamics), CRM platforms (Salesforce, HubSpot), BI tools, payment systems, and industry-specific software. For systems without modern APIs, we've built custom data pipelines using SFTP feeds, message buses, and database-level integrations.

For JLL, we integrated Salesforce, Sitefinity CMS, and regional data sources into a unified platform. Our approach uses microservices architecture and ESB patterns so each integration can be deployed, scaled, and maintained independently.

We follow compliance-first development practices aligned with HIPAA, SOC 2, GDPR, and PCI DSS. Every project includes encryption at rest and in transit, role-based access controls, audit logging for critical actions, and penetration testing before deployment.

For DispatchHealth, we implemented healthcare-grade security across microservices handling patient data. For JLL, we built GDPR compliance, rate limiting, and connection optimization into a global real estate platform. Security is built into the software architecture from day one.

We deliver enterprise software solutions across FinTech, Healthcare, Logistics, PropTech, eCommerce, Education, and Travel. Our client portfolio includes DispatchHealth (healthcare platform serving 300+ markets), JLL (Fortune 500 commercial real estate), Uniform (enterprise digital transformation platform), Bookis (eCommerce with 450K+ users), and Doctify (healthcare review platform across 6 countries).

Each engagement is built around the industry's specific compliance, workflow, and integration requirements. We bring domain expertise, not generic templates.

Start with three filters: relevant domain experience, a verifiable track record, and transparent communication. Ask for case studies in your industry with specific outcomes and named clients. Check how the company handles scope changes mid-project: rigid contracts signal a vendor, flexible engagement models signal a partner. Look at team retention rates because high turnover means you'll re-explain your business logic every few months.

At DBB Software, 80% of our clients stay 7+ years. We assign dedicated teams with deep product knowledge, so engineers working on your platform in month one are still there in year three. Every engagement starts with a scoped proposal, not a generic estimate, so you understand timelines, costs, and deliverables before signing anything.

Prioritize five things: proven enterprise-scale delivery (not just small apps rebranded as "enterprise"), compliance expertise relevant to your industry (HIPAA, SOC 2, GDPR, PCI DSS), the ability to integrate with your existing ecosystem (ERP, CRM, BI tools), a structured development process with clear milestones, and long-term support and maintenance capabilities.

Avoid companies that pitch technology before understanding your business problem. A strong enterprise software development company leads with discovery, mapping your workflows, data flows, and compliance requirements before recommending architecture. Check whether the company has delivered systems at your scale: building a dashboard for 50 users is fundamentally different from building a multi-tenant platform handling millions of transactions.

Look beyond the first project. Evaluate how the company handles post-launch support, feature evolution, and team continuity. Ask how many clients have worked with them for 3+ years, and request references from those long-term engagements specifically. A company optimized for one-off projects will deprioritize your maintenance requests once the initial build is done.

Assess cultural and process fit early. How do they communicate: async updates, weekly syncs, shared dashboards? Do they assign a dedicated team or rotate developers across clients? At DBB Software, our dedicated team model means your engineers build institutional knowledge of your platform over years, not weeks. That continuity reduces onboarding overhead, prevents knowledge loss, and accelerates every subsequent release.

Start with these: Who owns the intellectual property after delivery? What's your team structure, dedicated or shared across clients? Can you share case studies with measurable outcomes in my industry? What happens if requirements change mid-project? How do you handle security and compliance? What does post-launch support look like, and what does it cost?

Go deeper on process: ask them to walk through a recent project from discovery to deployment. Find out how they estimate timelines and what happens when estimates are wrong. Ask about QA: do they have a dedicated testing team, or do developers test their own code? The quality of answers to these questions reveals whether you're talking to a partner or a body shop.

It depends on the project. Large firms offer global reach and deep benches useful for simultaneous multi-region rollouts requiring 50+ developers. But that scale comes with overhead: account managers, multiple approval layers, and junior developers handling day-to-day work while senior engineers appear only during sales calls. Industry data shows large-scale traditional IT projects have roughly a 31% success rate.

Mid-size and boutique firms offer direct access to senior talent, faster decision-making, and tighter feedback loops. For legacy system modernization, enterprise software integration, or building a new platform from scratch, a focused team with domain expertise typically outperforms a large agency operating through layers of project management. DBB Software sits in this space with 100+ engineers, large enough to staff complex enterprise engagements, lean enough that your CTO talks directly to the architects building your system.
