whatsappx.si vs DoubleTick

DoubleTick is built by Apport Software Solutions in Mumbai and describes itself as an official WhatsApp Business API provider (about DoubleTick). It is aimed at sales-led businesses, especially in India, that message many customers at once.

As of October 2026, its strengths are things whatsappx.si does not offer: bulk broadcasts with customer segments and analytics, the Bot Studio chatbot builder, AI agents, product catalog sharing with an ordering bot, and Android and iOS apps (DoubleTick pricing; DoubleTick homepage). Larger teams get custom roles, a team hierarchy, and SSO and IP whitelisting on Enterprise. Google Sheets and Shopify integrations are included; Zoho CRM, HubSpot, Salesforce, Zapier and others are paid add-ons.

Some features are gated: Starter does not include AI agents, Bot Studio, conversation search or automatic agent assignment, and scheduled broadcasts are Enterprise-only (as of October 2026).

whatsappx.si is for teams that already run on a WhatsApp or WhatsApp Business app number and want more than one person answering it. Scan a QR code, the number becomes a linked device like WhatsApp Web, recent chat history syncs in, and everyone replies from one inbox at the same time.

On top of that inbox you get chat assignment, unread counts, search, live updates, owner/admin/agent roles with agents limited to assigned chats, multiple workspaces, email invites and keyword-triggered auto-replies you can switch on and off. A knowledge base lets teammates search your articles for answers by keyword. As extras, you can connect numbers through Meta’s official WhatsApp Business Platform, create templates that sync with Meta, and use a REST API with outbound webhooks.

For example, a dental clinic could link its number by QR code so the front desk and two assistants share the inbox and assign appointment chats to whoever is free. whatsappx.si does not have broadcast campaigns, a flow builder, built-in CRM integrations (only via API and webhooks) or native mobile apps.

DoubleTick connects only through Meta’s official WhatsApp Business API. As of October 2026, its Coexistence option, which keeps the WhatsApp Business app and the Cloud API on the same number, is available in India, works only with Business app numbers (not personal accounts) and is fixed at 20 messages per second (DoubleTick help: Coexistence vs API; Coexistence FAQs).

whatsappx.si offers two ways:

1. QR linking. Scan a QR code with an existing WhatsApp or WhatsApp Business app number. This uses WhatsApp’s linked-device feature, so its limits apply: up to four linked devices, and they log out if the phone is unused for more than 14 days (WhatsApp Help Center).
2. Official WhatsApp Business Platform. Connect numbers through Meta’s Cloud API with Embedded Signup in the app and several Meta numbers per workspace. Meta bills per delivered message separately (Meta pricing).

DoubleTick publishes plan prices that load by visitor location, defaulting to yearly billing. As of October 2026, according to doubletick.io/pricing:

Quarterly and half-yearly billing is also listed. Meta conversation charges are extra and vary by country (DoubleTick conversation costs). DoubleTick does not offer a free trial; prospects book a demo.

whatsappx.si has not published its prices yet; the pricing page lists its plans for the USA and India. For numbers on the official API, Meta’s per-message fees apply on top of either product.
