ERP System for Trade — Wholesale and Retail
An ERP system for trade that unifies B2B and B2C, wholesale and retail, physical stores, eMAG and your own online shop into one inventory, one pricing policy and one set of books. Orders, stock and payments move between channels in real time — no double entry, no discrepancies.
What the ERP covers
Partner price lists and multi-tier pricing
A dedicated price list per customer, chain or distribution channel. Volume-based multi-tier pricing, contract terms, promo windows and seasonal discounts — all applied automatically at order entry.
Multi-warehouse and multi-currency
Manage several warehouses and stores with transfers, reservations and real-time availability. EUR as base currency, supplier revaluations and automatic recalculation on imports from abroad.
ROS POS, eMAG and online-store sync
Two-way integration with ROS POS terminals in your stores and with eMAG Marketplace, WooCommerce, Shopify or a custom shop. One shared stock, one order pool, one customer history.
Invoices, proformas and credit notes
Issuing of invoices, proformas, credit and debit notes per Bulgarian standard, series per location, export to accounting software, e-invoices and gap-free numbering.
Supplier and customer AR / AP control
Credit limits, due dates, partial payments, advances and automatic aging. See which invoice is overdue, which client is at limit, which supplier is waiting for a transfer.
Discounts, promotions and B2B catalog
Discount rules per client, SKU, volume and period. A B2B catalog with personal prices and stock for your trading partners — no phone calls, no Excel files by email.
Who this wholesale and retail software is for
Distributors and wholesale
If you serve 50+ B2B clients on different terms, field sales reps and several suppliers, an ERP for distribution is non-negotiable. You get price lists, credit limits and per-customer margin control.
Retail chain with multiple stores
For chains of 2 to 50 locations we unify POS, stock and HQ in one real picture. See sales per store, inter-store transfers and what to replenish — without waiting until month-end.
Omnichannel brands
A physical shop plus an online channel, eMAG and your own site? Our omnichannel ERP merges every channel into one stock pool, one pricing policy and one customer history — wherever the order comes from.
How we build it
Tech stack — PostgreSQL for an ACID-grade database, REST API for integrations with Speedy, Econt, eMAG, Stripe and accounting software, a web app for HQ and stores and a mobile app for sales reps with offline mode. See also our ERP system development and API integrations services.
1. Discovery
We map processes, channels, pricing policies and integration points. Output — a tech spec and a fixed EUR quote.

We ship the core first — items, stock, orders, invoices — and put it into real use with the first users.
3. Integrations and POS
We connect eMAG, the online shop, ROS POS, couriers and accounting. One dataset, one source of truth.
4. Training and support
We train the team on-site, stay available with an SLA and evolve the system with your new channels and products.

Frequently Asked Questions
Can one ERP system for trade handle wholesale and retail at the same time?
Yes — that is exactly what it is built for. The same ERP processes B2B orders with contract pricing, credit limits and proformas, and in parallel B2C sales through POS, eMAG and the online shop. Stock is shared, while reports show margin per channel, per partner and per store in real time.
Does it support different price lists per partner?
Yes. We support unlimited price lists per partner, chain, region or distribution channel, together with multi-tier volume pricing and time-bound promotions. On order entry the right price and discount apply automatically, and in the B2B catalog each partner only sees their own terms — no email back-and-forth.
Does the ERP integrate with eMAG and an online store?
Yes. We have ready two-way integrations with eMAG Marketplace, WooCommerce, Shopify, OpenCart and custom shops via REST API. Stock, prices, orders and statuses sync automatically, while Speedy and Econt waybills are generated in one click. Payment status flows back into the ERP.
How much does an ERP for trade cost?
Starting investment for an MVP is from €5,800 — items, stock, orders, invoices and one integration. A full rollout with POS, eMAG, couriers and accounting typically runs €12,000 to €28,000. Pricing is a fixed EUR quote after discovery — no per-seat monthly fees, no surprise add-ons.
