Automate your accounting, GST compliance, inventory, and reporting with expert TDL development. Your Tally — built exactly for your business workflow.
Understanding TDL
TallyPrime is a powerful accounting platform trusted by millions of Indian businesses. But every business has unique workflows — custom invoice formats, industry-specific compliance requirements, specialised MIS reports, and integrations with other systems that standard Tally cannot handle out of the box.
Tally Customization solves this by using TDL (Tally Definition Language) — Tally's built-in programming language — to extend and modify TallyPrime without touching its core code. This means your customizations remain fully compatible with future TallyPrime upgrades.
At New Access Technologies, our TDL developers have 15+ years of experience building everything from simple invoice format changes to complex multi-branch ERP integrations across Bangalore, Hyderabad, and beyond.
TDL (Tally Definition Language) is the proprietary scripting language embedded in TallyPrime. It controls how data is displayed, calculated, printed, and exported. TDL files load into Tally at startup and can add new reports, change existing workflows, add custom fields, automate calculations, and connect Tally to external systems — all without modifying Tally's core executable.
Pricing starts from ₹2,000 for simple invoice format changes. Complex integrations are priced by scope after a free requirement study. We give you a detailed quote before starting — no surprises.

Client Success Stories
Here's how we've helped businesses in Bangalore and Hyderabad solve problems standard Tally couldn't handle.
A machine parts manufacturer in Peenya needed real-time raw material consumption tracking against production orders. We built a custom TDL-based BOM module that auto-deducts stock from each production entry and flags shortfalls before dispatch.
A pharmaceutical distributor needed Schedule H compliance with automatic FIFO-based expiry alerts. Our TDL solution added batch-level invoice tracking and a weekly near-expiry report sent directly from Tally via email.
A 12-outlet retail chain needed consolidated GST reports across multiple GSTINs from a single TallyPrime instance. We built a custom multi-GSTIN consolidation module that auto-generates GSTR-1 and GSTR-3B for each branch separately.
