Frequently Asked Questions

Got Questions? We've Got Answers!

Why not just use Zoho CRM or SAP instead of building custom?

Platforms like Zoho CRM and SAP are excellent for businesses with standard workflows and broad operational needs. However, companies with unique processes, industry-specific requirements, or growing operational complexity often benefit more from custom-built solutions. A tailored system focuses only on the features your business actually needs improving efficiency, scalability, and long-term cost effectiveness.

How long does it take to build a custom ERP or CRM?

A focused CRM with core modules takes 6–10 weeks. A full ERP with manufacturing, inventory, finance, and reporting is typically 3–5 months. We'll give you a module-by-module timeline before we start.

What happens to our existing data in Tally / Excel / old system?

We handle data migration as part of every project. We clean, map, and import your existing data into the new system you won't start from zero.

Will our team actually use it? Adoption is always the problem.

We build the UI around how your team already works, not how a software manual says they should. We also run hands-on training sessions and stay available during the first month post-launch. Adoption failure is usually a design problem we fix it at the design stage.

Can you integrate the new CRM/ERP with our existing tools like Tally or Shopify?

Yes. We connect your system to Tally, QuickBooks, Shopify, payment gateways, or any tool with an API. You don't have to rip everything out we plug in around what you already use.

How much does a custom CRM or ERP cost?

Every business is different a 5-user sales CRM and a 200-user manufacturing ERP are completely different projects. Rather than giving a number that may not fit your situation, we scope every project individually. Tell us what your current system cannot do and we will send a detailed estimate within 24 hours. No commitment required.

Is the source code ours after delivery?

Yes. You own 100% of the code, database, and intellectual property. There's no vendor lock-in.You can host it yourself or we can manage it for you.
