What Drives the Cost of a Custom Software Build?

We don't use mysterious hourly estimates. Our sprint plans price features according to these four technical drivers:

01

Workflow & Role Branches

A simple 2-role app (User/Admin) takes fewer sprints than a platform with 5 distinct permission tiers and multi-step approval gates.

02

Legacy Data Migration

Greenfield builds start instantly. Extracting, cleaning, and migrating 5 years of inconsistent spreadsheet or legacy SQL data adds dedicated sprints.

03

Hardware & Third-Party APIs

Standard REST APIs (Stripe, WhatsApp) are fast. Custom biometric IoT daemons, offline buffer sync, or ERP SAP adapters require deeper testing.

04

High Concurrency & SLA

Internal team tools run comfortably on modest cloud nodes. Consumer mobile apps handling 50k concurrent users require Redis queues and edge routing.

Change Governance

The 5-Step Change Request Transparency Guarantee

Software development should never involve surprise invoices. We operate with strict, contractual change transparency.

RULE 01

You Request a Change

Request an adjustment, new feature, or workflow modification at any time during development or weekly demos.

RULE 02

Written Assessment in 2 Days

Within 2 working days, we provide a 1-page change brief detailing the exact cost and impact on the delivery date.

RULE 03

Zero Work Without Sign-off

Nothing starts until you approve the change in writing. Invoices display approved changes as explicit transparent line items.

RULE 04

The Equal Swap Rule

If a requested change replaces a feature of equivalent engineering complexity, the project price does not increase.

RULE 05

30-Day Bug Warranty

Any defects in agreed features are resolved at zero additional charge during the 30-day post-launch warranty period.

30-Day Post-Launch Warranty Scope

Every fixed-sprint delivery includes a contractual 30-day post-launch warranty with dedicated engineer SLA and zero hourly billing.

What's Covered (Zero Cost)
  • Defects or deviations vs agreed acceptance criteria
  • Security, authentication, or API regression fixes
  • Production environment configuration adjustments
What's Excluded
  • New feature additions or scope changes
  • Third-party API downtime or breaking updates
  • Code modifications made by external developers
