Tally, your CRM, your inventory module, your databases, your file shares, even WhatsApp shop-floor photos. Every system below is production-tested today.If yours isn't on the list, it almost certainly still works. See below.
Five categories. Every system Kolossus reads today.
Organized by what the system does, not by region. Tally is in Accounting, Sell.do is in Sales & CRM, PostgreSQL is in Databases. Find your stack, see how we connect, move on.
Accounting & Tax.
Vouchers, ledgers, GST registers, books. Tally is the staple, the cloud books are well-handled.
Sales & CRM.
Indian real-estate CRMs, the global SaaS suite, and your in-house lead funnel. All read together.
Inventory, ERP & Ops.
SAP and NetSuite for the enterprise floor. Your in-house ERP, MRP, MES, WMS, and the master Excel sheet finance won’t give up.
Databases.
Whichever engine your back-office runs on. Schema auto-discovery handles the rest.
Files & Channels.
The unstructured edge of the business. WhatsApp photos, Excel masters, email POs, scanned forms, all read.
If you don't see it, we built for it.
The catalog above shows what we've actively built and tested. The reality is broader: if your system has a database, an API, exports files, or sends webhooks, Kolossus almost certainly reads it.
Most "new" connectors aren't really new. They're just another database or another API. Adding support is usually a matter of writing the schema mapping for your specific tables, not building from scratch.
If you've built your own CRM or ERP in PHP, Rails, .NET or Django, the full pattern is documented separately. Otherwise tell us what you run on WhatsApp and we'll tell you honestly.
Three columns. Honest boundaries.
"Supported" is a word vendors abuse. Here's what it specifically means for every connector above. What we read, what we can write back, and what we deliberately don't touch.
- All tables, fields, relationships the connection can see
- Continuous schema discovery. New fields picked up automatically.
- Cross-system joins at query time, no copying involved
- Field-level access controls. Hide sensitive columns.
- Multi-language data (Hindi, Gujarati, Tamil, Marathi, English)
- Tally voucher entry via official ODBC interface
- CRM record updates. Status, tags, notes, ownership.
- Approval-required. Every write logged with user + timestamp.
- Per-user permissions. Write access is granular and revocable.
- Custom systems via API if your system exposes write endpoints
- Your application code. We read data, not codebases.
- Filing PDFs to government portals. Your CA still files.
- Schema migrations. We don’t alter your database structure.
- System configuration. We don’t manage your Tally setup.
- Data outside your environment. Nothing copied externally.
