Tally already runs your books.Make it run your business.
TallyPrime and Tally ERP 9 customized to the way your business actually works — TDL development, custom reports and MIS, branded invoice and voucher formats, and modules built for your industry rather than the average of everyone's.
Overview
Where stock Tally stops, TDL starts.
Everything below is built on top of your existing Tally licence and data — no migration, no parallel system, no relearning the software your team already knows.
TDL Development
Custom Tally Definition Language programming for the business logic, validations and automation standard Tally doesn't ship with — written against your rules, not a generic template.
Custom Invoice & Voucher Formats
GST, export, multi-branch and fully branded print formats across every voucher type — laid out the way your customers, auditors and compliance filings expect them.
Custom Reports & MIS
Inventory, sales, outstanding, GST summaries and management dashboards — the numbers your leadership asks for, pulled straight from Tally instead of rebuilt in spreadsheets.
Custom Fields & Masters
New fields and masters on ledgers, vouchers and stock items — so the details your business tracks live inside Tally rather than in a side register nobody reconciles.
Workflow Automation
Approval flows, credit-limit checks, stock-level alerts and payment reminders wired into data entry — enforced at the point of entry, not caught weeks later.
Industry-Specific Modules
Manufacturing (BOM, job costing), retail and distribution (barcode, multi-location), trading, services and import-export — modules shaped by how each sector actually transacts.
Outcomes
What a Tally customisation is meant to change
The goal is fewer manual steps between what your business does and what Tally records.
Data entry cut at the source
Sales, purchase and payment data flowing in from your website, ERP or field application instead of being keyed a second time into Tally.
Vouchers that match how you trade
Custom voucher types, mandatory field validation and approval controls that reflect your actual process, not a generic default.
Reports your accountants stop rebuilding in Excel
Custom reports and print formats generated inside Tally, so the monthly pack does not depend on one person's spreadsheet.
Compliance filings prepared with less reconciliation
GST, TDS and e-invoice data captured correctly at entry, so return preparation is a check rather than a clean-up exercise.
Controls on who can change what
Role-based restrictions and edit logging on sensitive vouchers and masters, so changes are traceable.
Customisations that survive upgrades
TDL written to be maintainable and re-tested against new Tally releases, rather than a patchwork nobody dares touch.
Running Tally on one office machine?
Customization and hosting are two different problems. If your books also need to be reachable from other branches — with automated backups and access control — we host TallyPrime and Tally ERP 9 on our own cloud and VPS infrastructure.

How a Tally customization runs.
Understand the setup before changing it. Agree the blueprint before building it. Never test on live books.
- 01
Assess
Your current Tally setup, versions, data structure and day-to-day workflow mapped — with the gaps and manual workarounds documented as the actual brief.
- 02
Design
A customization blueprint covering fields, formats, reports and logic — reviewed and signed off with your finance and operations teams before a line of TDL is written.
- 03
Build & Test
TDL developed and tested in a sandbox copy of your company data — validated against real vouchers before anything touches production books.
- 04
Support
Team training, clean handover and ongoing updates as Tally versions change — so a release upgrade never quietly breaks what we built.
Tech stack
What the work is built on.
Chosen per engagement — matched to the Tally edition, data volume and integrations already in play.
Engagement model
How Tally engagements are structured
From a single report to a fully integrated Tally environment — sized to what you actually need changed.
Fixed-scope customisation
A defined set of TDL changes — reports, print formats, voucher types, validations — quoted and delivered against a written specification signed off by your accounts team before development starts.
Best for: A known list of gaps in your current Tally setup.
Integration build
Connecting Tally to your other systems — e-commerce, CRM, ERP, banking or a custom application — with mapping, scheduling, error handling and reconciliation reporting so failed records are visible rather than silently lost.
Best for: Duplicate entry between Tally and another system.
Support and enhancement retainer
Ongoing cover for your customisations: fixes, small enhancements, statutory and Tally version updates, and a monthly allocation of development hours, under an agreed response target.
Best for: Businesses depending on customised Tally daily.
Industries served
Built around how each sector actually books a transaction.
The same engine, configured for very different ledgers, stock models and compliance obligations.
