“Too many businesses buy ERP or CRM software that dictates how their team must work. At SprintStack, we design custom software around your real operational bottlenecks so your team gains visibility without complexity.”
Practical details on ERP & CRM engineering
Clear answers to common questions about timelines, data migration, and ownership.
Why should we build a custom CRM/ERP instead of using HubSpot, Salesforce, or Zoho?
Packaged SaaS tools charge recurring monthly per-seat fees that escalate rapidly as your headcount grows. More importantly, off-the-shelf tools force your business to adapt its unique operational workflows to generic software constraints. A custom system gives you 100% code ownership, zero license fees as you scale, and workflows mapped precisely to how your business actually operates.
Can you migrate our existing spreadsheets and legacy database records?
Yes. Data migration is a structured milestone in our delivery process. We audit your existing spreadsheets, clean and deduplicate customer records, construct relational schemas, and run dry-run validation scripts before the final cutover.
Who hosts the software, and will we be locked into SprintStack?
You host the software in your own cloud account (AWS, Google Cloud, Azure, or DigitalOcean). You own all repository source code, environment keys, and databases from day one. You are never locked into our agency; your in-house engineers or any third party can maintain and extend the system.
What is the typical timeline to launch an MVP?
A focused Custom CRM MVP typically ships in 8 to 12 weeks (4 to 6 sprints). A multi-department operational ERP typically ships in 12 to 16 weeks. We launch in phased milestones so your team starts benefiting from core modules early.
How are mid-project scope changes handled?
We operate with strict change transparency: if you want to add or modify features during development, we produce a one-page change request outlining the technical impact, extra sprint days, and exact cost. Work only commences once approved in writing.
What technical stack do you build custom ERPs and CRMs with?
We engineer enterprise systems using modern, highly maintainable technologies: Next.js (React) and Tailwind CSS for the user interface, Node.js/TypeScript on the backend, PostgreSQL for relational data integrity, Redis for fast caching, and Docker for portable containerization.
