The programs' real screens, with sample data. Click through the process yourself.
From order to shipping and receivables
Fourteen steps through SellM8 Warehouse with sample data: a customer order, stock set aside, a proforma with no retyping, stock per warehouse, picking and shipping, and what customers owe.
From the storefront to the analytics
Fifteen steps through SellM8 Shop with sample data: the customer picks a variant and orders without an account; you go into the admin panel straight from the shop, see the order, and then the same customer's path, the funnel, the channels that bring sales and the heatmap over the page itself.
From the catalogue to the enquiry
Twelve steps through SellM8 Catalog with sample data: the customer finds a product by category, sees its code, price and stock and sends an enquiry; you receive it in the admin panel and decide with one switch whether prices are shown.
Change the text yourself and see what works
Twelve steps through the SellM8 Sites admin panel: you change a heading without a developer, see it on the site, then look at visitors, a funnel, a heatmap, an A/B test and the enquiries. A demo site with made-up visits and enquiries.
From the monthly file to the forecast
Ten steps through SellM8 Analytics with sample data: uploading the report, dashboard, customers, sales reps, data cleaning and the forecast.
From invoice to paid
Twelve steps through SellM8 Invoice with sample data: a new invoice, sending it, automatic reminders, a payment found in the bank statement, and the month-end pack for the accountant. The program is not open to users yet — these screens come from its working version.
How they work together
Enter it once
This is how one order travels when the warehouse and the shop come from the same team.
-
The customer orders
The order from the online shop lands in the warehouse program automatically.
-
The warehouse reserves the stock
Stock is updated in both the shop and the catalogue.
-
You issue the documents
The invoice and the stock receipt come from the same order, with no retyping.
-
You see the result
Turnover, profit and receivables are in the reports the same day.
This is how SellM8 Warehouse, SellM8 Shop and SellM8 Catalog work today.
Why SellM8
What you gain when everything comes from one team
Six things we do differently.
-
You talk to the people who wrote it
We develop the programs ourselves. When something has to change, you do not wait for a third party.
-
Your data stays with you
The warehouse and the shop are installed separately for each company, each with its own database.
-
No third-party plugins
Couriers, payments, analytics and SEO tools are built into the programs.
-
Made for Bulgaria
Bulgarian interface and documents, prices in euros, Bulgarian couriers and banks, local VAT rules.
-
Every release goes through tests
More than 1,400 automated tests for the warehouse and 1,800 for the shop run before every change.
-
AI where it helps
An assistant that answers questions from your own data, and AI reading of received invoices. Everything also works without it.

Guides
Answers before you buy
Short, practical guides for owners of businesses that sell goods. They are useful even if you end up choosing a different program.
How to choose warehouse software: the questions to ask first Six groups of questions to put to any warehouse software vendor before you sign. Online shop and warehouse: why stock numbers drift apart Where the differences between shop stock and warehouse stock come from, and what to put in order so they stop. Catalogue with enquiries or a full online shop for wholesale? When a catalogue with an enquiry form is enough for a wholesaler, and when a full online shop with a cart is worth it.
Questions
The most common questions
What is SellM8?
SellM8 is the brand under which T&B Technology offers its own software for merchants: warehouse software with CRM, an online shop platform, an online catalogue, a platform for company websites, invoicing software and sales analytics.
Who is behind SellM8?
T&B Technology LTD — a digital agency from Ruse, Bulgaria. The team that develops the programs also installs and supports them.
Do I need all the programs?
No. Each one works on its own. When you use them together, data flows between them automatically — for example, orders from the online shop land in the warehouse.
How much do the programs cost?
It depends on the program, the modules and the size of the company. After a short call you receive a quote with the price and timeline.
Where is our data kept?
The warehouse program and the online shop are installed separately for each company, each with its own database. You never share a database with other clients.
