Ten real, defensible answers on what custom software actually costs in 2026 — MVP pricing, US developer rates, maintenance budgets, agency vs freelancer, and AI consulting fees.
Custom software in 2026 typically runs $25,000 to $250,000+ for US-built projects, depending on scope. A focused internal tool lands around $25K to $50K, a production SaaS platform $75K to $150K, and a multi-module enterprise system $200K and up. QUANT LAB USA quotes fixed-fee per phase after a paid discovery.
A real MVP — usable in production, not a prototype — runs $30,000 to $80,000 US-built. Tight scope (one core workflow, auth, payments, dashboard) lands around $35K in 6 to 10 weeks. Wider scope with integrations, role-based access, and admin tools pushes toward $75K. Offshore quotes are lower but rarely ship.
Senior US-based Next.js developers bill $125 to $250 per hour in 2026. Boutique agencies and founder-led firms typically run $150 to $200. Top-tier consultancies and ex-FAANG engineers reach $250 to $400. QUANT LAB USA prices most work fixed-fee per phase instead, because hourly billing rewards slow work and penalizes good engineers.
US engineers cost more because labor markets, healthcare, taxes, and cost-of-living are higher. You also pay for time-zone overlap, native-English communication, IP protection under US law, and accountability — there's a real entity to sue or refund. Most offshore-cheap projects end up rebuilt domestically, doubling the total spend.
Budget 15 to 25 percent of original build cost annually for maintenance, security patches, dependency updates, hosting, and incremental feature work. A $60K SaaS build typically needs $9K to $15K per year ongoing. QUANT LAB USA offers monthly retainers from $1,500 to $8,000 covering support, monitoring, and a defined feature-work allowance.
A fixed-price project at QUANT LAB USA includes discovery, design, build, testing, deployment, source-code handoff, documentation, and a 30-day post-launch warranty. Hosting costs, third-party API fees (Stripe, Twilio, OpenAI), and out-of-scope feature requests are billed separately. You get a written Statement of Work before any code is written.
AI integration projects typically run $8,000 to $60,000 depending on complexity. A focused Claude or GPT-4 integration into an existing app (chatbot, summarization, classification) lands around $10K to $20K. Custom RAG systems with vector databases and evaluation pipelines run $30K to $60K. Token costs are passed through at provider pricing.
In the US, custom software development is generally deductible as a business expense — but under IRC Section 174, software dev costs must be capitalized and amortized over 5 years (15 for foreign work) since 2022. Talk to a CPA. The 5-year domestic amortization makes US-built software materially cheaper after-tax than offshore.
A solo freelancer typically bills $75 to $175 per hour; a US agency runs $150 to $350 per hour or fixed-fee equivalent. Freelancers are cheaper hourly but carry single-point-of-failure risk. Agencies cost more but provide redundancy, process, and contracts. Founder-led firms like QUANT LAB USA sit in between — senior rates, no junior handoffs.
A real SaaS MVP — multi-tenant, auth, Stripe billing, dashboards, admin — runs $50,000 to $120,000 US-built. Tight single-feature SaaS lands around $55K in 10 weeks; multi-feature platforms with role-based access, integrations, and analytics push toward $120K. QUANT LAB USA ships these in 10 to 16 weeks on Next.js + Postgres + Stripe.
