How Tally Integration Works

1. Tally API Setup

Enable Tally API and configure OTP connection:

  • Enable Tally API in TallyPrime settings (F11 → API)
  • Set API port (default 9000) and authentication
  • Configure OTP with Tally server IP/hostname
  • Test connection and master data sync
  • Works with both Tally on local network and Tally on Cloud

2. Master Data Sync from Tally

OTP fetches Tally masters for validation:

  • Stock items (products, raw materials)
  • Units of measure (Kg, Pcs, Ltrs, etc.)
  • Godowns (warehouse locations)
  • Ledgers (customers, vendors, expense heads)
  • Scheduled sync (daily/hourly) or on-demand

3. Capture Operations Data

Barcode/RFID-based workflows capture transaction data:

  • Receiving: Scan items, capture weight, vendor details
  • Dispatch: Pick items, customer selection, pack quantities
  • Production: Material consumption, finished goods output
  • Transfers: Scan at source location, destination location
  • All data validated against Tally masters

4. Automatic Voucher Posting to Tally

OTP creates Tally vouchers via API:

  • Build voucher XML/JSON based on Tally schema
  • Include all required fields (date, voucher type, ledgers, stock items)
  • POST voucher to Tally API
  • Receive voucher number back from Tally
  • Store Tally voucher reference in OTP for audit trail

The Challenge

  • Each batch required recording: customer, kit type, quantity, weight
  • Manual transcription from paper registers to Tally invoices
  • Errors in data entry causing billing disputes
  • Billing cycle took 2-3 days after service completion

  • Auto-Invoice: All data flows to OTP → Sales Invoice created in Tally
  • Customer details, kit types, quantities, weights pre-filled from workflow
  • Pricing fetched from Tally rate masters
  • One-click invoice generation—no manual entry

Results

  • 50% faster billing cycle - Same-day invoicing vs. 2-3 days
  • Zero manual Tally entry - All automated from workflow
