Zoho Books invoices and payment reminders on WhatsApp

Invoice PDF on WhatsApp

When an invoice is ready in Zoho Books, Go4whatsup sends it to the customer on WhatsApp with the PDF attached, using an approved template with the customer’s name, invoice number, amount and due date. The customer opens it on their phone, and the message and PDF are logged on the customer’s record, so finance and sales can both see what was sent and when.

The invoice message can include buttons, such as a link to your payment page or a quick reply to confirm receipt, so the customer can act without leaving the chat. If they reply with a question, the message lands in the shared inbox and on their Zoho record, where finance or the account owner can answer it.

Payment reminders

Payment reminders go out on WhatsApp the same way, with the invoice PDF attached, so the customer has the amount, the due date and the document in one message. Each reminder uses an approved template, so customers get a clear, consistent message instead of an ad-hoc text from a sales rep’s personal phone.

Quotes, purchase orders, renewal notices

The same flow works for other documents. Zoho CRM quotes go out as WhatsApp PDFs when a deal reaches the proposal stage, and purchase orders, renewal notices and delivery or handover documents can be sent the same way. Rules are set per Zoho module with conditions, so a template only goes out when a record matches every condition you choose.

Why send documents on WhatsApp

Invoices sent by email often sit unread in a crowded inbox or a spam folder, and the first sign of a problem is a late payment. Customers check WhatsApp many times a day, so an invoice that arrives there is far more likely to be opened the same day. The customer can open the PDF, ask a question or confirm payment in the same chat, and the reply reaches your team instead of a no-reply address.

Every document and message is logged on the customer’s Zoho record, so finance can see what was sent and when, and sales can see whether an invoice is still open before calling the customer. Because the business number is shared, nobody needs to forward invoices from a personal phone.

Template examples

Invoice: “Hi {{name}}, your invoice {{number}} for {{amount}} is attached. Due on {{date}}. Reply here if you have a question.”

Reminder: “Hi {{name}}, a friendly reminder that invoice {{number}} for {{amount}} is due on {{date}}. The PDF is attached.”

Quote: “Hi {{name}}, your quote {{number}} is attached and valid until {{date}}. Tap below to approve or ask a question.”

Invoices, payment reminders and order updates normally use Meta’s Utility category, which costs less per message than Marketing. Meta decides the final category when it reviews the template.

Go4whatsup Standard is $39/month (AED 149 / SAR 149 / ₹1,499) with unlimited agents. The Free Forever plan covers 2 agents. The AI chatbot is an add-on on Standard, priced by AI usage, and included in Pro and Enterprise. WhatsApp message charges are separate: Meta’s per-message rate plus a platform margin, shown in the app before you send.
