Sign-in and registration via MAX
The customer presses a button, confirms the sign-in in a chat with your store bot and comes back to the storefront signed in. No password to invent, no e-mail to confirm, no SMS code to wait for.
Two steps press the button on the site, confirm in the messenger
|
No per-message cost the bot writes to the customer for free — no SMS gateway needed
|
The number is verified the messenger signs the phone number it sends; it cannot be forged

CS-Cart 4.17.1+ and Multi-Vendor, all four editions

The problem it removes
Registration is the narrowest point on the way to an order. Invent a password, type an e-mail, wait for the letter, confirm the address: every step costs a share of the people who wanted to buy.
Signing in with an SMS code is shorter, but it has a price of its own: messages are paid for by the month and by the piece, the code arrives late, and with some operators it does not arrive at all.
Two taps to an account
A button in the sign-in form, a confirmation in the messenger — and the customer is in their account. No password, no e-mail address. |
The phone number is verified
The number arrives with a signature the store checks with the bot key. Somebody else’s number cannot be substituted without that key. |
Nothing beyond the price of the add-on
The bot is free, its messages are free, there is no subscription. No SMS budget is needed for signing people in. |
Joins the stock sign-in form
The button appears both on the sign-in page and in the pop-up. Nothing to place by hand, no templates to edit. |
The “Sign in with MAX” button in the stock sign-in form, next to the usual e-mail and password.
What the customer sees
- • Presses the button. On a computer a window opens and hands them to the messenger; on a phone the MAX application opens straight away.
- • Confirms the sign-in. The bot says hello and asks to share contact details — one button inside the chat.
- • Comes back to the store. The tab refreshes itself and the customer is in their account.
- • Next time it is instant. The bot recognises a returning customer and lets them in without asking for a contact again.
The sign-in pop-up: the button is there too, not only on a page of its own.
Signed in: the bot confirms and the store tab refreshes by itself.
What the store gets
- • A customer with a verified phone number. The number comes from the messenger rather than being typed in, so the database has no typos and no invented numbers.
- • Returning customers recognised. If the customer already exists, the sign-in goes into their existing account with the whole order history — the number is matched in every spelling the store itself produces.
- • Registration of new ones, if you want it. A setting keeps MAX sign-in for registered customers only.
- • Support that can answer. The customer profile shows whether they sign in through MAX and offers an unlink button, so “I cannot log in” takes a minute.
The customer profile: the MAX sign-in is visible, with an unlink button.
A customer created by a MAX sign-in: the phone number is verified by the messenger, the e-mail is a placeholder.
Settings
Exactly as many settings as it takes to start the sign-in and to decide two questions of store policy.
- • Bot token and username — what the messenger issues when the bot is created.
- • Connection — one button; the store fills in the update address itself and shows the state of the connection.
- • Register new customers — whether people may register themselves by phone number.
- • Sign-in attempt lifetime — how long the store waits for a confirmation; unfinished attempts clear themselves up.
Bot settings: token, username, update address and connection state.
Sign-in behaviour: whether to register new customers and how long an attempt lives.
Customer personal data
A line under the MAX button links the terms of use and the personal data processing policy of the store. The addresses are set in the add-on settings; the policy defaults to the page selected in the GDPR add-on.
When a customer registers with MAX or links it to an existing account by phone number, the GDPR consent log records the line they saw, the document addresses, the sign-in method, the IP address and the browser. Customers who linked MAX earlier get an entry on their next sign-in. A regular registration in the store is recorded there as “Registration”, and only when the customer ticked the consent box.
Getting started
STEP 1
Install the add-on
Through the Cart-Power Add-ons Manager — updates arrive the same way. |
STEP 2
Create a bot in MAX
Inside the MAX application the service bot @MasterBot creates yours with the /create command. Free, a few minutes; the manual walks through every step. |
STEP 3
Fill in the token and username
Both are issued by @MasterBot when the bot is created. |
STEP 4
Press “Connect bot”
The store tells the messenger where to deliver events, and the button appears on the storefront. |
Check this beforehand
The storefront has to open from the internet over HTTPS: MAX delivers events to secure addresses only. One bot serves one storefront — a second storefront needs a second bot.
What it does not do
Better said up front than discovered in support.
- • It does not replace the usual e-mail and password sign-in — the button stands next to it.
- • It does not send letters, order notifications or promotions through the bot: the bot is there for signing in.
- • It does not open the admin panel: customers sign in through MAX, staff and vendors do not.
- • It does not bring an e-mail address — the messenger does not pass one on, so a new customer gets a placeholder address and can replace it in their account.
Frequently asked questions
Is there a subscription fee?
No. The add-on is bought once, the bot is free and its messages are free. No SMS budget is needed for signing people in.
Do I need my own bot, and is it hard to create?
The bot has to be yours — it talks to customers on behalf of your store. It is created for free inside the MAX application through the service bot @MasterBot and takes a few minutes. The manual walks through every step and every command.
What happens to customers who are already registered?
They sign in to their existing account: the store looks the customer up by phone number in every spelling it produces itself — brackets, spaces and dashes make no difference.
Can I allow only existing customers to sign in?
Yes, there is a setting for it: with registration switched off the bot tells an unknown customer to register on the site first.
Does it work alongside SMS-code sign-in and Sber ID?
Yes. The button joins the same row as the other sign-in methods and does not interfere with them.
Is HTTPS required?
Yes, it is: MAX delivers events to secure addresses only. A storefront without a certificate cannot accept the bot, and the add-on says so when you try to connect it.
What about a multi-storefront store?
One bot serves one storefront. A second storefront needs a second bot with its own token.
One step in, instead of a registration form. Read the manual — it walks through creating the bot step by step, with every command.

CS-Cart development · in-house team · since 2013 We build, upgrade and speed up CS-Cart stores and marketplacesAnalysts, developers, designers, QA and support under one roof — no subcontractors.

Two add-ons that change how a store performs
Everything else we publish improves one screen. These two change the numbers: how customers find products, and how often they come back.
|
Add-on · Search & merchandising Smart SearchElasticsearch-powered search for large catalogues. The customer types two letters, sees products with images and prices, and buys from the dropdown — even after a typo or with the wrong keyboard layout. Visitors who use the search bar are 24% of traffic and 44% of revenue, and convert about 2.5× better than people who only browse categories. If search returns nothing, up to 80% of them leave. | ||||||||
| ||||||||
Try it on a live catalogue: open the demo store and search with a deliberate typo. |
|
Add-on · Mobile commerce PowerApp — mobile app for your storeA native iOS and Android app running on your CS-Cart data: the same products, prices, stock, promotions, reward points and orders. There is no second catalogue to maintain — everything stays in the admin panel you already use. A mobile site brings a customer in once; an app brings them back for free. Push notifications replace the retargeting budget you spend to buy the same customer a second time. | ||||||||
| ||||||||
Screens, block types and pricing tiers: see how the app is built. |
Services
When no add-on solves it, we do the work
Fixed scope, written specification, a named project manager and a warranty on what we ship.
|
Custom CS-Cart development Functionality the platform does not have: add-ons, marketplace mechanics, integrations with 1C, CRM, ERP, payment and delivery providers. We start from a written specification, not from an estimate on a phone call. Details → |
|
CS-Cart upgrade Move to the current version without losing data, custom code or add-ons. We audit every modification first, upgrade on a staging copy, adapt what breaks and switch over with little or no downtime. Details → |
|
Speed and performance optimisation Conversion falls by about 4.4% for every extra second of load time. We profile the server, the database and the front-end, then fix what actually costs the seconds — and show you the before-and-after numbers. Details → |
|
Design for CS-Cart Mobile-first storefront design built on CS-Cart's own template structure, so the layout survives the next platform upgrade instead of becoming a migration problem. Details → |
|
SEO for CS-Cart A technical audit of indexing, duplicates, redirects, structured data and Core Web Vitals — delivered as a prioritised fix list your developers can act on, or that we implement ourselves. Details → |
How we work
What you get besides the code
|
Before we start We discuss the goal, offer options and write the specification. You approve scope and price before development begins. |
While we build A named project manager reports progress on a fixed schedule. You always know what is in work and what is next. |
|
Before release A separate QA pass on every release — the developer who wrote the code is not the person who signs it off. |
After handover Documentation for everything we ship, plus a warranty on the modifications and the project. |
Tell us what the store needs to doDescribe the task in a couple of sentences and we will come back with options, a scope and a price. The consultation is free, and we will say plainly if a ready-made add-on already solves it.
