How to use WACRM's free WhatsApp tools

All five tools below live on the free tools hub at wacrm.ai/tools. Every one of them runs instantly in your browser, shows a complete result with no sign-up, and links back to the WACRM guide or feature that goes with it. This tutorial walks through each one in turn, with the exact fields to fill in and a screenshot of the real result.

What you need before you start

• A WhatsApp number in international format — your own, or a placeholder like +1 555 123 4567 if you just want to try a tool out.
• Nothing to install or connect: every tool runs instantly in your browser.
• About two minutes per tool — each one shows a complete result right away, with no sign-up.

Step by step: all five tools

1. Estimate a broadcast’s cost with the message pricing calculator. Pick the recipient’s country from the Country dropdown — for example Brazil — then choose a Message category (Marketing, Utility & Authentication, or Service) and type how many messages you expect to send into Messages per month. The estimated monthly cost updates instantly: it is just your volume multiplied by Meta’s own per-message rate for that market, with 0% markup from WACRM. 1,000 Utility & Authentication messages to Brazil comes to $6.80, matching the message pricing guide.

   

2. Make a chat link and QR code with the link + QR code generator. Type a WhatsApp number in international format — such as the placeholder +1 555 123 4567 — into WhatsApp number, and optionally write a greeting that opens pre-typed in the chat. The wa.me link and a downloadable QR code both update as you type; copy the link for a bio or email signature, or download the QR code as a PNG for packaging and print. Switch to Bulk from CSV to generate a whole list of links at once (see the CSV format below).

   

3. Build a site button with the chat widget generator. Enter your WhatsApp number, then customize the greeting message, button label, corner position and accent color — the Live preview updates as you edit each field. Once the number is valid, click Copy snippet and paste the result just before </body> in your site’s template, theme footer or custom code block; nothing it does is routed through WACRM.

   

4. Score your profile with the profile grader. Go through the 11-item checklist honestly, for your profile as it is today. Two items — business address and product catalog — have an N/A option for a fully online or services-only business; every other item is a plain yes/no. Your score updates live from 0 to 100, and each unanswered “No” becomes a red issue card below the checklist with the points it costs and a short fix.

   

5. Work out your ROI with the ROI calculator. Fill in only the section that matches your business: No-show calculator for a service business that takes bookings, COD / RTO calculator for cash-on-delivery ecommerce, or Abandoned cart calculator for any online store. Start from the presets shown, then adjust any rate that isn’t a fact for your own market — the estimated monthly loss and what automated WhatsApp reminders could realistically recover both update as you type.

   

Bulk links from a CSV

The link + QR code generator’s Bulk from CSV mode accepts one row per link: phone, then an optional message, then an optional campaign name. A header row containing the word “phone” is detected and skipped automatically.

phone,message,campaign
+15551234567,Hi there!,spring-sale
+15559876543,,spring-sale

Nothing in bulk mode is uploaded anywhere — like the rest of the tool, it runs entirely in your browser, and you download the finished list as a CSV of generated links.
