What “instant” looks like for the customer<\/h2>\n\n ![\"Instant](\"https:\/\/www.fast2sms.com\/help\/wp-content\/uploads\/2026\/07\/tally-whatsapp-invoice-sample.png\")
Seconds after the voucher saves: invoice PDF, order number, invoice number, date and amount, signed with your business name.<\/figcaption><\/figure>\nThe message goes through the official WhatsApp Business API, so it arrives as a proper business template with a delivery report behind it, not a forwarded file from someone’s personal number.<\/p>\n
One-time setup (about ten minutes)<\/h2>\n\n- Install:<\/strong> download the plugin<\/a>, load the .TCP file in TallyPrime (Local TDL or Account TDL), enable the WhatsApp module under F1 > TDLs & Add-ons > F6. Full TDL install detail: TDL for Tally to WhatsApp<\/a>.<\/li>\n
- Connect:<\/strong> paste your API key from your free Fast2SMS account<\/a>.<\/li>\n
- Two defaults:<\/strong> type 123456789<\/strong> as WABA Phone Number ID in WhatsApp API Settings, and message IDs T101 to T120<\/strong> in Template Settings. Twenty pre-approved templates, nothing to wait for. Mapping table: complete plugin guide<\/a>.<\/li>\n
- Numbers:<\/strong> customer mobiles in ledger masters, bulk update, or Excel import.<\/li>\n<\/ol>\n
Turn on instant sending<\/h2>\n
This is the setting that makes it automatic: open the voucher type<\/strong> (for example Sales), find the plugin’s WhatsApp options, and enable send on voucher creation<\/strong> (and on alteration if you want corrections re-sent). From that moment:<\/p>\n\n- Operator saves the invoice \u2192 WhatsApp goes out. Zero extra keystrokes.<\/li>\n
- Works per voucher type, so you can auto-send sales invoices but keep payments manual, or any mix.<\/li>\n
- Each send is logged in the Delivery Report inside Tally and in your panel.<\/li>\n<\/ul>\n
Prefer a human check before each send? Leave auto-send off and use the send button on the voucher screen; a preview shows the message and the customer’s number, one confirmation and it is gone.<\/p>\n
Clear the backlog in bulk<\/h2>\n
Instant covers new invoices; the sales register covers old ones. Open the register, select any set of invoices, and send them all on WhatsApp in one action. The same works for bulk outstanding reminders<\/a> from Statement of Account.<\/p>\nWhat it costs<\/h2>\n
The plugin is free, with no licence and no renewal, while comparable paid Tally WhatsApp modules sell for \u20b93,000\u2013\u20b96,000 plus GST (see the price comparison<\/a>). You pay per message only, on delivery basis; failed WhatsApp messages auto-refund to your wallet within 48 hours. The same plugin also sends every voucher as DLT SMS with the invoice PDF as a short link, covered in the Tally SMS plugin guide<\/a>.<\/p>\n\n Download Tally Plugin<\/a>\n<\/p>\nFrequently asked questions<\/h2>\nHow fast does the invoice reach the customer?<\/h3>\n
Within seconds of saving the voucher when auto-send is on. The plugin generates the PDF, fills the template and sends through the API immediately.<\/p>\n
Does instant sending need my computer to keep WhatsApp open?<\/h3>\n
No. Sending happens through the official WhatsApp Business API from the server side; no WhatsApp Web, no QR scan, no phone dependency.<\/p>\n
Can I choose which vouchers send instantly?<\/h3>\n
Yes, auto-send is set per voucher type: sales instant, receipts instant, payments manual, any combination.<\/p>\n
What if the operator makes a mistake on the invoice?<\/h3>\n
Enable send on alteration and the corrected invoice re-sends when saved again, or keep alteration sends manual and use the voucher button.<\/p>\n
Do I need my own WhatsApp number for instant sending?<\/h3>\n
No, the default sender (123456789 + T101 to T120) works instantly. Your own brand sender is a free switch later: Tally WhatsApp sender guide<\/a>.<\/p>\nIs there proof the customer got it?<\/h3>\n
