One Shop, One WhatsApp Number, One Long Day: What WhatsMax Actually Feels Like to Run

You know this site as the place you come when a form asks for your email and you would rather not give the real one. But think about the other side of that exchange. Somewhere a shop's phone is buzzing with the exact kind of messages you send as a customer: "Is this in stock?", "What time do you close?", "I want to order two." Somebody has to answer those, and for a small business that somebody is usually whoever happens to be holding the shop phone.

That is the problem WhatsMax is built around, and it is worth understanding from the shop floor rather than from a feature list. WhatsMax is a multi-vendor WhatsApp marketing platform: campaigns, a shared team inbox, bots, a product catalog, contacts, drips and billing, run from one WhatsApp Business number. It is sold as a script for $44 one-time on codester.shop (Regular License, listed as a Laravel 13 SaaS, instant ZIP download), and its live demo runs at mavora.tempomailusa.com, where a free plan is included with no credit card to start, according to the demo's own landing page. Instead of walking through its menus, let us walk through one shop's day with it, hour by hour.

7:40 in the morning: the phone stops being passed around

The day starts the way it always does: the shop phone has messages from overnight, and the first person in picks it up. In a lot of small businesses this is where the trouble starts, because the phone is a single object and the business is not a single person. The owner answers a question one way, the staff member answers it differently later, and a customer who asked about delivery yesterday gets asked for their address again today. Nobody is being careless. The tool just was not built for a team.

WhatsMax replaces the passed-around phone with a shared team inbox. Every conversation from the business number lands in one place, and team members work from their own logins, with owner and staff roles. Labels, assignment and contact details sit beside the chat, so the person picking up a conversation can see what has already been promised. The landing page makes a point of the 24-hour service window being shown on every conversation — WhatsApp only allows free-form replies for 24 hours after the customer's last message, and after that you need an approved template to reopen the chat. An inbox that hides that countdown sets its staff up to reply late by accident.

There is a second, quieter benefit. The inbox is not WhatsApp-only: the landing page says Facebook and Instagram conversations come into the same place too. For a shop that takes orders on three apps, that is the difference between checking three phones and checking one screen.

10:15 in the morning: the broadcast that used to take all morning

Mid-morning is campaign time. The shop has a festive offer, or a new batch, or a price change, and it needs to tell its customers. WhatsApp does not allow a free-for-all: broadcasts go through approved message templates, which Meta reviews before they can be sent, and they go to contacts who have opted in.

WhatsMax treats the campaign as a measurable job rather than a message sent into the dark. You pick a template, map its variables (the landing page gives the example of {{1}} mapped to contact fields, so each customer gets their own name or offer filled in), choose the audience from groups and labels, and send now or schedule for later. A running campaign can be paused, sending is paced per number with quiet hours, and the landing page describes sending as atomic — a campaign does not half-send and leave you guessing who got it. Afterwards, every campaign shows sent, delivered and read percentages, with a per-recipient log behind them. The log matters more than the percentage: it tells you who did not get the message, and that is the list you act on.

Contacts come in by CSV or Google Sheets import, organised with groups, labels and custom fields, and opt-outs are respected automatically. That is not a courtesy feature: on a channel where Meta sets the rules, sending to people who asked you to stop is how a number gets restricted.

1 in the afternoon: the customer who wants to buy inside the chat

Lunch brings the customer who does not want a link, a website and a checkout. She wants the thing, in this chat, now. WhatsMax syncs a Meta Commerce catalog, and from the chat composer a staff member can send a single product, a product list, or the whole catalog — or use a catalog as the content of a campaign. Orders placed from those messages arrive in an orders inbox inside the console, next to the conversations that started them.

This is the feature most likely to be oversold, so let us be precise. It is not a shop website. It is a way to put a product card — name, price and all — into a conversation that is already about buying. For a store that sells on chat anyway, that removes the step where the customer leaves the chat and never comes back. The landing page also notes you can hide a product from the pickers without changing anything in your Meta catalog, so a discontinued item stays in the catalog but nobody offers it by mistake.

4 in the afternoon: the board on the wall, but for contacts

Afternoons are for sorting. WhatsMax gives contacts a kanban board: drag a card to move a contact between groups, with membership updating on the spot, labels, quick notes and the open chat right on the card. If you have never run a customer list, this sounds like decoration. If you have, you know the alternative is a spreadsheet nobody updates, where a "hot lead" from March is still marked hot in October because nobody opened the file.

The board only helps if the groups mean something, and that is a discipline problem no software solves. Groups like "asked about pricing" or "needs follow-up" are useful. Groups like "misc" are where contacts go to be forgotten, board or no board. The drip sequences sit in the same afternoon logic: day-by-day sequences, automatic follow-ups when a chat goes quiet, and birthday greetings drawn from contact dates, all window-aware — free-form messages inside 24 hours, templates after.

9 at night: the questions that arrive after closing

The shop closes. The questions do not. "What are your timings?" "Do you deliver to my area?" "Is the offer still on?" These are the same five questions every night, and answering them the next morning means answering them late.

WhatsMax offers three layers, and the distinction between them matters. Keyword auto-replies handle exact or contains matching on the words customers actually type, replying with free text or an approved template, per rule. The visual flow builder turns a bot into a designed conversation — greetings, questions, button menus, branches and actions — with a live phone preview and a test mode that walks the whole flow like a customer, sending nothing and saving nothing until you publish. And an AI chat bot answers in its own words when no rule matches. Bot replies count against the plan limit, according to the landing page.

Here is my opinion, plainly: buy the bot for the five questions you already answer fifty times a week, and do not buy it for the conversations that need a human. A bot that answers "what time do you close" at midnight is a good employee. A bot that tries to negotiate a refund at midnight is a liability. Test mode is what tells you which one you built.

The next morning: the desk after closing

So far this has been the vendor's day. WhatsMax is multi-tenant, so there is a second customer: the person who runs the platform itself. Owners get a central console for vendors, subscriptions, transactions, credits and platform settings. Resellers sign up through their own link, set their own markup over the plan prices, manage their child vendors, and see only their own earnings ledger. Payments go through eight gateways, according to the landing page, and every payment is verified before a plan activates.

Three complete guides ship with the product, the landing page says: an Admin Handbook, a Vendor Guide and a Staff Quick Guide. Most scripts ship a readme and a prayer; guides for three different roles suggest the maker has watched three different people get confused. There is also a REST API and signed webhooks — the landing page claims 100% of webhooks are verified by signature before anything is processed — plus a mobile console installable as an app. And the landing page's headline claim: 28 paid add-ons built into the core — catalog, kanban, drips, tasks, referrals and more — at no extra cost.

What it costs, honestly

Two different prices live on two different pages, and confusing them is the easiest mistake in this post, so let us separate them. The $44 is the price of the script itself: one-time, Regular License, from codester.shop/shop">the shop listing. That buys the code to run your own WhatsMax platform, for your own vendors or your own business, on your own server. The demo site's own subscription plans are a different thing: they are what a platform owner charges their vendors. The demo lists a Free plan at $0 (100 contacts, 10 campaigns a month, 500 messages a month, 5 bot replies, 1 bot flow, 3 custom fields, 1 team member, 1 workspace), a Growth plan at $29 a month (5,000 contacts, 100 campaigns, 10,000 messages, 50 bot replies, 5 flows, 20 custom fields, 5 team members, 3 workspaces, plus the AI bot, API access, catalog, flows forms, web chat, social channels and WhatsApp calling), and a Scale plan at $99 a month with unlimited contacts, campaigns, messages, bot replies, flows, custom fields, team members and workspaces. Meta's own conversation charges are separate and set by Meta, as the landing page says explicitly.

So the real cost of running this is $44 for the code, plus hosting, plus Meta's per-conversation charges, plus your time. The real cost of using a platform like it is whatever that platform's plan charges. Neither is free, and "free plan" on the demo means the platform's free tier, not the script.

Who should not buy it

If you are one person answering your own business WhatsApp, and the WhatsApp Business app already does what you need, do not buy anything. A shared inbox for a team of one is a filing cabinet for a single letter. If your customers do not use WhatsApp, or your sales happen entirely on a website with a checkout, this is the wrong tool however good it is. And if you want a WhatsApp platform but never want to touch a server, do not buy the script — use a hosted platform (this demo's free plan exists so you can try that shape first) and pay the monthly plan instead. Buying the script only makes sense if you want to run the platform: your own vendors or resellers, your own plans, your own server to look after.

Frequently asked questions

What exactly is WhatsMax?

A multi-vendor WhatsApp marketing platform sold as a script: campaigns, a shared team inbox, bots and a visual flow builder, a product catalog, contacts with a kanban board, drip sequences, and billing with reseller support, run from a business WhatsApp number. Its live demo is at mavora.tempomailusa.com and the script is listed at $44 one-time on codester.shop.

Do I need Meta approval to send campaigns?

For broadcasts, yes — broadcasts use message templates, which Meta reviews before they can be sent. You create templates in WhatsMax, map their variables, and submit them from the console; approval status is tracked for you. Replies inside the 24-hour service window do not need a template.

What happens when the 24-hour window closes?

The inbox shows the window state on every chat, and when it is closed you reopen the conversation by sending an approved template message. Drips and follow-ups are window-aware, so they switch between free-form messages and templates accordingly.

Can my team share one WhatsApp number?

Yes. That is the point of the shared inbox: every conversation from your business number arrives in one place, and team members work from their own logins with owner and staff roles. Higher plans include more team seats.

Can customers buy without leaving the chat?

Yes, through the catalog: sync your Meta Commerce catalog once, then send a single product, a product list or the full catalog from the chat composer, or use a catalog as a campaign's content. Orders arrive in an orders inbox inside the console.

Does WhatsMax charge for Meta's messages?

No. Meta charges per conversation on the WhatsApp Business Platform, at a rate that depends on the conversation category and the customer's country, billed by Meta, not by WhatsMax. The WhatsMax plan covers the platform itself.

What is the difference between buying the $44 script and using the demo's free plan?

Buying the script gives you the code to run your own platform, on your own server, with your own vendors and plans. Using the demo's free plan means using somebody else's running platform, within its free limits (100 contacts, 10 campaigns and 500 messages a month). One is ownership, the other is tenancy, and the right one depends on whether you want to run the shop or rent a counter in it.

So the next time a business answers you on WhatsApp at midnight, or sends you an offer that actually has your name in it, you will have a better idea of what is on the other side of that chat: probably a team inbox, probably a template, possibly a bot, and — if the shop runs its own platform — possibly WhatsMax, bought once for $44. The demo at mavora.tempomailusa.com lets you try the vendor side free, and codester.shop/shop">the shop listing has the script itself. And if you only ever need a throwaway inbox for signups, the tool on this site's homepage will still be here, free, or with extra domains on the VIP plans. Earlier in this series, we toured the script behind this very website — the temp-mail code running the inbox you use here. For more from the people who run this site, visit the blog index.
