ERP for an online store: inventory, orders and couriers
We build ERP systems for merchants selling through their own online store, eMAG, physical POS locations or multiple brands. You get shared inventory, one order flow, warehouse operations, courier, payment and accounting integrations.

Is ERP right for your online store?
ERP makes sense when orders come from more than one channel or your team wastes time copying data between the store, warehouse, courier and accounting software. Instead of several administrative panels, you work with one shared source of information for products, customers, orders and inventory.
The system is suitable for stores with multiple warehouses, a dark store, a physical location, a B2B catalogue or more than one online brand. If you are just starting in e-commerce and have one channel, standard online store development may be enough. ERP starts delivering value when manual work leads to errors, delayed shipments or inventory discrepancies.
What does the system manage?
Catalogue and inventory across channels
One shared inventory can supply your own website, eMAG and POS. When a sale is made, the quantity changes according to the defined rules, while your team can see inventory by warehouse. The catalogue can include variants, bundles, low-stock thresholds and different prices for your website, marketplace and B2B channel.
Orders from your website, eMAG and POS
Orders from WooCommerce, Shopify, OpenCart, PrestaShop, your own store, eMAG and POS are collected in one list. Statuses follow your actual process: paid, to be picked, packed, shipped, delivered, returned or cancelled. This prevents operators from processing the same order twice.
Warehouse, picking and returns
For multiple warehouses, the system supports reservations, transfers and inventory by location. Picking lists can be organized by zone, and work can be carried out using a phone or scanner. Returns go through an RMA process with condition checks, replacements, refunds, restocking or write-offs.
Invoices, payments and accounting data exchange
Invoices, pro forma invoices and credit notes are issued according to your business rules. Data can be prepared for Microinvest, Ajur, ERP.NET or Biznes Navigator. When needed, we configure series by channel, electronic invoices and the automated exchange of the required documents.
Couriers and payments
We connect Speedy, Econt, Stripe, myPOS and other services according to your process. A waybill is created for each order, its status is sent back to the system, and the operator can see the payment method, amount and delivery status in one place. The specific data exchange depends on the API capabilities and your agreement with the provider.
Operational reports
Managers and teams can track orders by status, sales by channel, inventory, returns, delayed deliveries and products that frequently go out of stock. Reports are selected based on the decisions you make, not a predefined template.
Which platforms and services does it integrate with?
We work with WooCommerce, Shopify, OpenCart, PrestaShop, eMAG and custom stores through REST API. We also connect POS systems, Speedy, Econt, Stripe, myPOS and accounting software. When no ready-made connector exists, we describe the data exchange and limitations in the technical specification. Learn more about how we connect systems in our API integrations service.
What is included in the different scopes?
| Scope | What it includes | Price |
|---|---|---|
| MVP | Catalogue, inventory, orders, invoices and one channel integration | €3,000-€29,300 |
| Extended implementation | Multiple channels, eMAG, couriers, payments, accounting export and additional workflows | €3,000-€29,300 |
| Additional modules | Multi-warehouse, mobile picking, multi-brand, custom reports and non-standard integrations | Specified in the quote |
The price depends on the number of channels, products and variants, warehouse logic, invoicing method, returns, roles and limitations of external APIs. The migration of product catalogs, customers and inventory is estimated based on the quality and format of the data. After the analysis, we define the scope and prepare a quote for the agreed version.
How does the build process work?
- 01Process analysis
We map the channels, SKU structure, pricing, warehouses, courier mix, payment methods and accounting touchpoints. We also document exceptions: partial deliveries, refusals, replacements and pre-orders.
- 02Technical specification and quote
We determine which modules will be included in the first version, where an off-the-shelf connector is available and where a custom API is required. You receive a specification, project phases and a quote for the agreed scope.
- 03MVP and migration
We build the core with a catalog, inventory, orders and invoices. We import the prepared data and connect the first primary channel. If needed, the old and new systems can run in parallel during a verification period.
- 04Channels, couriers and accounting
We add eMAG, the store platform, Speedy, Econt, Stripe, myPOS and the accounting data exchange according to priorities. We test statuses, duplicate orders, failed payments, returns and inventory discrepancies.
- 05Training and support
We show the warehouse, customer service and administration teams how to use the system. After launch, we monitor the processes, resolve issues and plan the next modules based on actual usage.
What do you need to prepare?
- A list of the channels, stores, POS locations and warehouses.
- An export of products, variants, prices, customers and inventory.
- Rules for reservations, shipping, refusals, returns and replacements.
- Access credentials and API documentation for the platform, eMAG, couriers, payment providers and accounting software.
- A member of the operations team who can confirm how an order is actually processed.
What experience can we show?
For a production and warehouse environment, see Testen Dom, ERP for production and B2B. The project includes requests from email, production batches and recipes, FEFO inventory with expiry dates, barcodes, invoices and reports. It is an example of how warehouse logic and sales are organised around the actual process, rather than around separate, disconnected screens.
Frequently asked questions
Which online store platforms does the system work with? We work with WooCommerce, Shopify, OpenCart, PrestaShop, eMAG and custom stores via REST API. If the platform has no ready-made connector, we define the data exchange during the analysis.
Can you connect eMAG to a warehouse and courier? Yes. If API access is available, offers, prices, inventory, orders and statuses can be exchanged. Waybill creation depends on the specific courier API and your contract with the provider.
Can I start with just one online store? Yes. The first version can include one store and one channel integration, while eMAG, POS, a second warehouse or a new brand can be added later. The data and architecture are planned with this expansion in mind.
How long does the build take? An MVP is usually planned for 6-10 weeks when the data and access credentials are ready and the scope is clear. Additional channels, migrations, warehouses and non-standard rules extend the timeline.
How much does an ERP for an online store cost? For an ERP project, we use the range €3,000-€29,300. The exact position within the range is determined after analysing the channels, warehouses, integrations, migration and specific rules.
