Both routes solve the same problem — Tally does not do something you need. The right choice depends on how standard your requirement is and how quickly you need it live.
When a ready-made add-on wins
- Your requirement is common: GST invoice formats, ageing reports, stock controls, bulk import
- You need it working today, not in two weeks
- Budget matters — a ready-made add-on typically costs a fraction of custom work
- You want a product that is already tested across many installations
When custom development is worth it
- Your process is unique to your industry or company
- The add-on must exchange data with your own software, website or ERP
- You need specific approval workflows or user-level controls
- You want exclusivity over the resulting solution
Questions to ask before you buy
- Which Tally editions and releases does it support?
- Is the licence per serial number, per machine or per company?
- Are updates for future Tally releases included?
- What does support cover, and for how long?
- Can you see a demo on your own data before paying?
A practical middle path
Many businesses start with a ready-made add-on and pay a small customisation fee for the two or three changes they need. This keeps the cost near the product price while still fitting your process.
Frequently asked questions
How long does custom TDL development take?
A small report or print format is often ready in a few days. Larger workflow or integration projects take longer and are usually scoped in stages.
Is a ready-made add-on customisable?
In most cases yes — the developer holds the source and can add fields or change layouts for a modest fee.
