A transparent pricing guide for custom software development based on 500+ projects we have delivered. Real numbers, not marketing ranges — $25K–$60K for simple builds, $300K–$500K+ for enterprise scale.
| Tier | Price Range | Timeline | Best For |
|---|---|---|---|
| Internal Tool | $25K–$60K | 6–14 weeks | Single-purpose tool for internal use: dashboard, form processor, reporting tool, workflow automation. |
| Business Application | $60K–$150K | 14–28 weeks | Customer-facing application with multiple user roles, integrations, and business logic. |
| Enterprise Platform | $150K–$300K | 28–40 weeks | Complex platform with microservices, compliance, multi-tenant, advanced security, and analytics. |
| Large-Scale System | $300K–$500K+ | 40–60+ weeks | Mission-critical system with high availability, disaster recovery, complex integrations, and regulatory compliance. |
Break-even math for IT buyers. Ranges are indicative and vary by scope/region.
SaaS wins until you have 100+ seats, need workflows the SaaS vendor won't ship, or the data lives where SaaS can't reach. A $120K custom build breaks even vs SaaS at roughly 80 seats + 4 years of use.
Duct-tape automations are fine until something breaks. When the workflow is mission-critical (revenue or compliance), custom software breaks even within 18 months on reliability alone — outages in stitch-ups typically cost $5K–$25K each.
In-house beats agency past ~18 months continuous development. For a defined 6–9 month build + a year of iteration, agency total is 35–50% cheaper.
Quick answer: Custom software development costs $25,000–$500,000+ depending on scope, complexity, and team size. A simple internal tool costs $25K–$60K. A mid-complexity business application runs $60K–$150K. Enterprise platforms cost $150K–$500K+. Want a tailored estimate? Talk to us →
Simple CRUD applications cost 3-5x less than event-driven microservices with complex business rules, state machines, and real-time processing.
Integrating with legacy systems, ERPs (SAP, Oracle), or proprietary APIs can cost $10K–$50K per integration due to documentation gaps and data mapping.
SOC 2, HIPAA, PCI DSS, or industry-specific compliance adds $20K–$80K for security architecture, audit controls, and certification preparation.
Migrating data from legacy systems requires ETL pipelines, data cleaning, validation, and rollback planning — adding $10K–$40K.
Systems designed for 100 users cost less than those designed for 100,000. High-traffic architecture adds $15K–$40K for caching, load balancing, and database optimization.
SLA-backed support (24/7, 4-hour response) costs $2K–$10K/month. Basic business-hours support costs $1K–$3K/month.

Practical steps we use with clients to control scope and spend.
Plan for discovery, a realistic MVP, and a 15–20% contingency before you lock a number for custom software development. Scope changes and integrations are where estimates drift — we help you sequence work so you fund value in the right order.
Ranges reflect a mid-complexity business application: multi-role access, 3–5 integrations, custom workflows, and a modern web frontend.
| Vendor Type | Typical Cost | Timeline | Risk Profile |
|---|---|---|---|
| Freelancer / dev collective | $20K–$75K | 4–10 months | High — limited PM/QA, integration gaps surface late, handoff docs often thin |
| Offshore agency (IN/PK/UA) | $40K–$120K | 5–11 months | Medium — lower rate but legacy-system integration and security reviews often under-scoped |
| Nearshore agency (LATAM/EE) | $70K–$200K | 4–8 months | Low-medium — timezone aligned, strong engineering culture, solid on ERP/API integration patterns |
| US/EU agency (ZTABS tier) | $90K–$280K | 4–8 months | Low — senior team, production enterprise experience, compliance-ready (SOC 2/HIPAA) when needed |
| Big 4 / systems integrator (Accenture, Deloitte) | $250K–$800K+ | 8–16 months | Low on delivery risk, high on cost — heavy PMO overhead, 2–3× the burn rate of boutique agencies |
Ranges are 2026 US-buyer benchmarks; legacy-system integration (SAP, Oracle, mainframe) and compliance layers (SOC 2, HIPAA, PCI) add $20K–$80K regardless of vendor. Ongoing maintenance runs 15–25% of build cost annually.
Honest scenarios where the numbers above are the wrong benchmark for your situation.
Monday, Asana, HubSpot, Salesforce, Airtable — if a $50–$200/seat/mo tool covers most of the job, customize it with Zapier/Make integrations ($3K–$10K) instead of building from scratch. Custom software makes sense only when off-the-shelf genuinely fails.
Paving cow paths is a classic money pit. Bad processes encoded in $200K of custom code are locked in for a decade. Budget for a process audit first and fix the workflow before automating it.
Custom software needs hundreds of small decisions. Projects stall 2–3× longer without a single decision-maker — we've seen $150K builds balloon to $300K just from decision latency. Appoint one before starting.
Real build-vs-buy options with pricing signals and the honest gotcha each one carries.
| Alternative | Best For | Pricing Signal | Biggest Gotcha |
|---|---|---|---|
| Off-the-shelf SaaS (Salesforce, NetSuite, Monday) | 80% fit on standard process, non-differentiating workflows, buy-over-build default | $15–$300/user/mo + $10K–$80K implementation at $150–$250/hr | License sprawl at scale. A 200-seat Salesforce deployment with add-ons runs $180K–$400K/yr; a custom build breaks even at ~month 28. |
| Low-code platform (Mendix, OutSystems, PowerApps) | Enterprises with IT governance, form-heavy workflows, 10–100 internal users | $50–$200/user/mo + $25K–$150K build at $120–$220/hr | Vendor lock-in is near-total. Exporting a 3-year-old Mendix app to regular code is a full rebuild, not an export. |
| Custom build (agency) | Real differentiation, legacy integrations, 3+ year roadmap | $60K–$300K+ over 14–40 weeks at $90–$180/hr | Custom only pays off if you can staff ongoing maintenance. Without a 15–20% annual budget, custom software rots into a compliance liability in 18 months. |
| In-house engineering team | Core-to-business software, continuous 5+ year roadmap, 4+ engineers of work | $400K–$1.2M/yr loaded for a 3-engineer team + PM/QA | Hiring cycle is 4–6 months. Churn (20% industry avg) resets context. Without senior tech leadership, team produces a maintenance burden faster than value. |
Client asked for a sync to their 18-year-old AS/400 ERP. Discovery found the ERP had no documented API, only a flat-file nightly export. Integration scope tripled from $12K to $38K. Always do a 2-week discovery before fixed-price on legacy integrations.
Agency built a $180K custom platform, client in-house team took over. Zero tests + sparse docs = 4 months of unproductive onboarding and a key hire quit. Require a written handoff package (runbook, test coverage, ADRs) as a contract deliverable.
IT scoped a $220K build with operations; finance blocked launch because it did not reconcile with the GL. 9 weeks of rework. Get budget-holder sign-off on requirements, not just the functional user.
