Ckassa Payment Integration
$0.00

Accepting payments in Russia is not only about the card form: a fiscal receipt has to be issued under federal law 54-FZ, and you need confidence that payments will not stop if one bank has an outage. The add-on connects a service that covers both, and costs nothing itself.

What the connection gives you

  • Free fiscalisation — receipts are issued by the service, so there is no online cash register to buy and maintain.
  • Uninterrupted acquiring — the system works with three banks in parallel and switches over if one of them fails.
  • Security — the card is not stored on the site and payments go through 3-D Secure.
  • A rate from 3.1%, decreasing as the volume of card payments grows.
  • Works in the Ultimate and Multi-Vendor editions.

When it helps

Stores launching in Russia that would rather not invest in cash register hardware, and projects for which a payment outage caused by a single bank means direct losses.

Support and updates

The add-on is free. Connection and creating a payment method are covered in the documentation; installation questions go through HelpDesk. Service terms and pricing are set by ckassa.ru.

FAQ

Do I need an online cash register?

No, payments made through the service are fiscalised automatically — the requirements of 54-FZ are met by the provider.

How much does the add-on cost?

The add-on is free; you only pay the acquiring fee under the service's pricing — from 3.1%, decreasing with turnover.

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 Search

Elasticsearch-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.
Constructor, Beyond Relevance Report 2025; Google Cloud × The Harris Poll, 2023

Catalogue size Sub-second results on 300,000+ products, Multi-Vendor included
Understands Typos, wrong keyboard layout, synonyms, word forms, SKUs, brands and attributes
Reporting Query analytics — what customers search for and which searches return nothing
Deployment Our cloud, or Elasticsearch on your own server

from $35/month

Add-on · Mobile commerce

PowerApp — mobile app for your store

A 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.

Platforms Native iOS and Android, published under your own developer account
Home screen Built in the admin panel from six block types, the same way you build website pages
Time to launch Under a week from purchase to submission for App Store and Google Play review
Compatibility CS-Cart and Multi-Vendor 4.18–4.20 · 11 client apps already live in the stores

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 do

Describe 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.
