Transparent Pricing
Own your software. Pay once.
We engineer custom business software with a fixed-cost milestone pricing model. No subscriptions, no seat licenses, and zero vendor lock-in.
The Milestone Pricing Model
Unlike SaaS providers who bill you monthly per seat, or software development agencies charging hourly rates that lead to scope creep, ERPStack operates strictly on fixed-price milestone delivery.
1. Discovery & Architecture
We establish the entity-relationship diagrams, VPC networking schemas, data residency boundaries, and API ingestion specs, creating a concrete engineering blueprint before writing code.
2. Phased Milestone Building
We implement vertical slices of application logic in bi-weekly sprints. Every milestone is deployed to a staging environment and verified with automated test suites before signing off.
3. Code Handover & Sunset
At completion, we hand over full code ownership. This includes the Git repository, Terraform state files, database migration histories, and environment secrets. The software becomes your capital asset.
Typical Custom System Budgets
Custom software is a high-yield asset. Below are the typical fixed-cost project ranges based on operational scope and compliance requirements.
Standard B2B Operations
Single-tenant system with isolated relational databases, role-based access control (RBAC), custom workflow states, basic reporting filters, and secure integrations with up to two third-party REST APIs. Delivery: 6–8 weeks.
Discuss PlanCompliance & Multi-Tenant
Multi-tenant SaaS platform featuring schema-level database isolation, built-in compliance logging (HIPAA/SOC2 controls), automated backup routines, custom invoice engines, and 5+ deep integrations. Delivery: 10–16 weeks.
Discuss PlanEnterprise Scale Infrastructure
High-frequency transactional ledgers, double-entry bookkeeping systems, ClickHouse analytics nodes, multi-region active replicas, specialized inventory pipelines, and automated source code escrow. Delivery: 18–24 weeks.
Discuss PlanTotal Cost of Ownership (3-Year Horizon)
Renting standard SaaS software is a continuous taxation. Building custom software creates a capital asset that pays for itself within months.
