ERP for Online Store — Stock, Orders, Couriers, Invoices
An ERP for an online store keeps inventory, orders, couriers and invoices on one source of truth. Past 100 orders a day across your shop, eMAG and a physical POS, manual sync becomes the bottleneck — oversells, courier delays and accounting gaps start eating margin.
What this e-commerce ERP includes
Real-time stock sync between shop, eMAG and POS
A single stock pool feeds your own online shop, eMAG Marketplace and the physical POS. Every sale decrements stock everywhere in seconds, so oversells stop happening even on best-sellers running on three channels at once.
Unified order processing
Orders from WooCommerce, Shopify, OpenCart, eMAG and the POS land in one queue with one status flow — paid, picking, packed, shipped, returned. One screen for the operations team, no tab juggling.
Automated invoicing into your accounting
Invoices, proformas and credit notes are issued automatically per Bulgarian standard and exported into Microinvest, Ажур, ERP.NET or Бизнес Навигатор. Gap-free numbering, series per channel, e-invoices included.
Multi-warehouse and picking
Run several warehouses or dark stores with transfers, reservations and picking lists optimised by zone. Mobile picking on a phone or scanner, with real-time stock visibility per warehouse for the customer service team.
Pricing per channel and returns workflow
Different prices per channel — own site, eMAG, B2B catalog — with promo windows and bundle rules. Returns get a guided workflow: RMA, condition check, refund or replacement, restocked or written off.
KPI dashboard for e-commerce ops
A live dashboard with cart abandonment, AOV, repeat-buyer rate, courier on-time delivery and stock-out frequency — the metrics your team acts on.
Who this ERP for online store is for
Stores with 100+ orders a day
Past 100 orders a day, spreadsheets and the platform admin stop scaling. An ERP for online store gives you queues, automation and SLA visibility so the team grows in revenue without growing in headcount.
Omnichannel retailers
If you sell on your own site, eMAG and a physical shop, you need one stock and one customer history. Multi-channel commerce only works when the back office sees every channel as part of the same business.
Multi-store and multi-brand operators
Run several stores or brands under one company? We give you a tenant model with shared catalog, separate pricing, separate invoicing and consolidated reporting — without spinning up a new system per brand.

Frequently Asked Questions
Which online store platforms does this ERP work with?
We have ready two-way connectors for WooCommerce, Shopify, OpenCart, PrestaShop and custom shops over REST API. Stock, prices, orders and statuses sync continuously, and an eMAG Marketplace connector plugs straight in. If you run on a niche platform we build the integration in the discovery phase and ship it with the MVP.
How many stores can I unify under one ERP for online store?
There is no hard limit — we run clients with one shop and others with eight brands across three countries on the same instance. The tenant model lets you share catalogs where it makes sense, separate pricing and invoicing per brand, and roll consolidated reports up to the holding level without spinning up a new system per store.
Can it sync with eMAG Marketplace?
Yes. eMAG is a first-class channel — we sync the offer feed, stock, prices, orders and statuses, generate Speedy and Econt waybills against eMAG orders in one click and reconcile payouts back into accounting. Cancellations, partial shipments and returns flow through the same workflow as your own site.
How much does an ERP for online store cost?
An MVP starts from €6,800 — catalog, stock, orders, invoices and one channel integration. A full rollout with eMAG, multi-warehouse, couriers and accounting export typically runs €14,000 to €30,000. Pricing is fixed in EUR after discovery — no per-seat monthly fees, no surprise change requests, no hidden percentages on GMV.
