Sign In with SberBusiness ID — a wholesale customer in one tap
A representative of a company signs in to the store with its SberBusiness account. The store receives the company name, its tax numbers, the e-mail and the phone from the bank — the data a registration form usually asks for and a manager later has to verify.

Why a wholesale store needs it
A company fills in more than anyone at registration: the name, the tax numbers, the address, the phone, the contact person. Part of the customers leave at that step, and those who finish mistype the digits — so a manager checks the details against the bank statement afterwards.
One tap instead of a form
The customer confirms the sign-in in SberBusiness and comes back to the store signed in: no password, no form. |
Details you can trust
The company name and the tax numbers come from the bank, so the database holds no invented numbers and no typos. |
No duplicate customers
The next sign-in recognises the company and leads to the same account with the whole order history. |
No code to edit
The button joins the stock sign-in and registration forms: no theme templates to change. |
The “Sign in with SberBusiness ID” button on the store sign-in page.
The same button in the sign-in pop-up from the header.
One-tap company registration
- • The company name and the tax numbers are filled in from SberBusiness ID — the customer types nothing.
- • The e-mail and the phone come from the same place, verified by the bank.
- • A button on the registration page. A customer who opened the form does not have to fill it in.
- • No password needed. The account is created from the bank data, and the next sign-in works the same way.
The registration page: the form can be skipped — the company account is created from the SberBusiness ID data.
Connection and settings
The add-on is set up in the administration panel: Client ID, Client Secret and the TLS certificate from the SberBusiness ID account. No code and no templates to edit.
- • Test mode — the requests go to the Sber sandbox, so the connection is proven before the live store uses it.
- • Button priority — SberBusiness ID stands first among the third-party sign-in buttons.
- • ID token signature check against the Sber key set, when the bank gives its address.
- • Logging — every call or the failed ones only, as configured.
What the bank issues
The store applies in its SberBusiness account and receives a Client ID, a Client Secret and a TLS certificate for its domain. The manual walks through it step by step.
Connection settings: credentials, the certificate and the ID token check.
Security: what was checked and closed
The add-on works with the keys that issue tokens on behalf of the store, so the bar is higher than usual. Version 1.1 closed everything the code review found.
- • Secrets never reach the log. The Client Secret, the codes, the tokens and the authorisation headers are masked before the record is written — and that is visible in the log itself.
- • The gateway certificate is verified. The connection runs over mutual TLS with full verification.
- • The answer is matched against the request. One-time state and nonce, the signature and the fields of the ID token: a mismatch stops the sign-in and lands in the log.
- • The encryption key belongs to the installation. A dump of another store does not open your credentials.
The log of the gateway calls: successful calls and refusals alike, with the secrets masked.
Linking and unlinking a company
SberBusiness ID is linked to a customer account rather than replacing it. The customer sees the link in their account, the administrator — in the customer profile, on the “Add-ons” tab, together with the unlink button.
The customer profile in the panel: the link is visible and unlinking takes one button.
Customer personal data
A line under the SberBusiness ID 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 SberBusiness ID or links it to an account, the GDPR consent log records the line they saw, the document addresses, the sign-in method, the IP address and the browser. A regular registration in the store is recorded there as “Registration”, and only when the customer ticked the consent box.
The organisation details are saved to the account: the name goes to the “Company” field, and the INN and KPP are shown on the customer page in the admin panel.
How to start
STEP 1
Install the add-on
Through the Cart-Power Add-ons Manager — updates arrive the same way. |
STEP 2
Apply in SberBusiness
In the company account: the return address and the certificate. |
STEP 3
Fill in the credentials
Client ID, Client Secret, the certificate and its password go into the add-on settings. |
STEP 4
Check the sign-in
Open the sign-in page: the button is there. Try test mode first, then go live. |
What to know in advance
The storefront must run over HTTPS: Sber accepts a secure return address only. The credentials are issued to the store under its contract with the bank, not to the add-on developer.
Frequently asked questions
How is this different from “Sign In with Sber ID”?
Sber ID signs in a private customer, SberBusiness ID signs in a company. Here the store receives the company name and its tax numbers instead of a first and last name.
What happens if the customer already has an account?
SberBusiness ID is linked to that account and the sign-in leads into it, with the whole order history. No duplicate is created.
Can a company be unlinked?
Yes — by the customer in their account and by the administrator in the customer profile.
What is needed for the button to appear?
A Client ID, a Client Secret and a TLS certificate from the SberBusiness account. The store obtains them itself; the manual describes the order of steps.
Does the add-on log anything?
Yes, into the stock event log: every call to the gateway or the failed ones only. The secrets in the records are masked.
Does it work in Multi-Vendor?
Yes, in all four editions.
See the add-on on the demo store. The storefront button, the settings, the call log and the customer profile are all open. A live sign-in is not possible there: the Sber gateway only accepts the production credentials of a store.

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.
