I need an experienced TDL developer to take my current Tally.ERP 9 setup to the next level. I already have some scripts in place, yet a growing set of requirements means parts of that code must be refined while several brand-new modules are written from scratch. The immediate scope covers three areas: • Custom reports – management-oriented layouts that pull data from multiple ledgers and display month-to-date, year-to-date and variance figures on one screen, ready for PDF or Excel export. • Voucher-type tweaks – additional fields, validations and auto-numbering rules that make data entry faster and error-free. • Smooth import / export – one-click CSV-to-voucher and voucher-to-CSV routines for daily data exchange with our e-commerce platform. All development has to remain fully compatible with Tally.ERP 9; no TallyPrime features should sneak in. I will supply: • The existing TDL codebase and sample data. • Field maps and mock-ups for the new reports. • Test cases that each script must pass before sign-off. Deliverables will be handed over as well-commented .tdl files with a short README explaining how to deploy them through Tally Developer IDE and load-on-startup. If you are confident writing clean, modular TDL and can demonstrate previous work on custom reports or voucher extensions, I’d love to work with you.
