One-Click Tally Prime Automation

I need a developer who can wire my in-house order-management app directly into Tally Prime so that routine accounting tasks fire off with a single click. The core flow is simple: from our application we create an order, press “Sync,” and Tally should instantly issue the corresponding Sales Invoice, Sales Voucher and Delivery Order without any manual re-keying.

Alongside those vouchers, the integration must handle customer records in both directions—new customers created in our app should appear in Tally, existing ones must update seamlessly, and all customer details must be retrievable for display inside our UI. Think of it as live, bidirectional customer data management sitting on top of synchronous voucher posting.

I am open to whichever approach you prefer—Tally XML/ODBC, the newer Tally Prime API or a lightweight middleware service—so long as it is reliable, handles errors gracefully and keeps performance snappy. Provide well-documented code, basic install instructions and a short test plan that proves:

• One-click generation of Invoice, Sales Voucher and Delivery Order from a sample order
• Automatic create / update / fetch functions for customer data
• Confirmation back to our application that each transaction posted successfully or returned an error

If you have already built similar Tally automations, let me see a quick demo or outline; that will speed up the decision.
