Get an instant estimate for your software development project in under 2 minutes.
Estimates based on real project data, not guesswork.
Aligned with market rates and complexity factors.
See exactly where your investment goes.
The estimator computes a total project cost range from your project type, complexity level, and selected integrations. Each project type carries a base range at basic complexity, from $12,000 to $40,000 for a mobile app up to $25,000 to $80,000 for custom enterprise software. Complexity multiplies that range by 1.0 to 2.5, each selected integration adds a flat $4,000, and the complexity level also sets the timeline and team estimates.
The tool returns an estimated investment of $44,000 to $116,000, a 6-9 month timeline, and a team of 5-6 developers plus 1 project manager.
| Project type | Base minimum | Base maximum |
|---|---|---|
| Warehouse Management System | $20,000 | $60,000 |
| HRMS / Payroll System | $15,000 | $50,000 |
| SaaS Application | $18,000 | $55,000 |
| Mobile App | $12,000 | $40,000 |
| E-commerce Platform | $15,000 | $50,000 |
| Custom Enterprise Software | $25,000 | $80,000 |
Bases are the basic-complexity cost for each type, aligned to the published build cost ladder. The published single-site WMS band ($30,000 to $64,000, ERP included) lands between this tool’s Basic and Standard complexity for a WMS with one ERP integration.
| Complexity | Cost multiplier | Timeline | Team |
|---|---|---|---|
| Basic (core features only) | x1.0 | 2-3 months | 3-4 developers, 1 PM |
| Standard (common features plus customizations) | x1.4 | 3-6 months | 3-4 developers, 1 PM |
| Advanced (complex workflows plus integrations) | x1.8 | 6-9 months | 5-6 developers, 1 PM |
| Enterprise (full-scale, high compliance) | x2.5 | 9-12 months | 8-10 developers, 2 PMs |
| Add-on | Cost |
|---|---|
| Each selected integration (ERP, CRM, payment gateways, accounting, third-party APIs, legacy systems, IoT devices, email/SMS) | +$4,000 flat |
$4,000 is roughly 160-200 hours at the published $20-$30/hour band, a realistic single-integration effort.
These are the same bases and multipliers the estimator above runs on (CostEstimator.tsx).
