IT solutions in Mumbai often come down to one of three jobs: replacing spreadsheets with a proper system, connecting tools that do not talk to each other, or building software for something no ready made product covers. ByteArray Technology Solutions builds CRM, ERP and custom software for Mumbai businesses, and agrees the scope in writing before any code is written.
Where Mumbai businesses need their own systems
Trading, import export and logistics firms handle a great deal of paperwork, much of it tied to cargo moving through the port at Navi Mumbai: shipping documents, invoices, GST filings and payment follow ups. When that lives in scattered Excel files, mistakes are inevitable and month end takes days.
Wholesalers and distributors have a related problem. Orders arrive by phone and WhatsApp, stock sits in several godowns, and the accountant works in Tally. A system that takes an order once and carries it through stock, invoice and payment saves the same data being typed three times.
What we usually build
- A CRM that tracks every enquiry, quotation and follow up, with reminders for the salesperson.
- An ERP module set for stock, purchase, sales and accounts, sized to your business and not to a large enterprise.
- Data exchange with Tally, so invoices and ledgers do not have to be entered twice.
- Web portals and mobile apps for customers, agents or field staff.
How a project runs
We begin with a discovery call and ask for sample documents: an invoice, a stock sheet, a typical order. From those we write a scope that lists every screen and report. Development happens in short stages, and you see a working demo every week. Your staff is trained before launch, and the code sits in a repository you own.
What we need from you
Three things make projects go smoothly: sample documents from your daily work, a list of the people who will use the system, and one person with the authority to approve changes. Small internal tools often take four to eight weeks. Full ERP work takes longer, and the plan is broken into phases so you get something usable early.
