CUSTOM SOFTWARE
When the physical store, the warehouse and online sales work with separate information, the team spends time checking stock, updating prices and following orders by hand.
At ENOR, we build platforms that connect these processes around your business model. From a single shop to a network of points of sale, we develop the functions and integrations you need to work with clearer information.

CHALLENGES WE ADDRESS
Each situation maps to a concrete software function. The aim is more clarity, not a promise of zero errors or guaranteed sales growth.
Product quantities differ between store, warehouse and website.
Shared inventoryThe same product or order is entered several times in different tools.
Catalogue and integrationsDiscounts and price lists are handled by hand.
Pricing rulesOrder status is followed by email, phone and spreadsheets.
Order managementIt is unclear which sale was returned and what happened to the item.
Linked returnsEach store has its own figures and combining them takes time.
Consolidated reportingSOLUTIONS WE DEVELOP
Development options selected and combined per project, not an off-the-shelf program with every module included.
Interfaces for sales, payments, returns and daily operations.
Products, movements, supplies and stock by location.
Connecting purchasing, sales, inventory and administration.
Coordinating physical and online channels.
From receiving and stock reservation to picking and delivery.
Customer history, preferences and reward programmes.
Interfaces for customers, staff and self-service.
Views of activity, products and channel performance.
POS SYSTEM DEVELOPMENT
Custom POS software follows the way your cashiers work: fast search, clear buttons and actions based on permissions.
Four steps we keep separate
Integrations with scanners, printers and terminals depend on the device, its drivers and the available interfaces.
Basket
Discount needs manager permission
Tap products to add them to the basket, then try the payment: each step appears separately.
INVENTORY AND WAREHOUSES
An inventory program that separates what is physically on the shelf from what can be sold. SKU (Stock Keeping Unit) is the unique code of each product or variant.
Four quantities that never get mixed up
| SKU | Product | Variant | Qty |
|---|---|---|---|
| AT-42-BK | Run sneakers | 42 · Black | 40 |
| AT-43-BK | Run sneakers | 43 · Black | 18 |

PHYSICAL AND ONLINE SALES
Omnichannel connects sales channels and their processes around shared information.
Online order
Product reservation
Preparation in store
Pickup or delivery
We define which system is the main source of inventory and how quantities are synchronised between channels.
Selling products that are out of stock (overselling) is limited by reservations and timely updates; it cannot be ruled out without these controls.
ORDERS AND DELIVERY
Picking means collecting items from the shelves; packing is packaging them. Order, payment and shipment statuses are tracked separately because they change at different times.

Rules by priority
Change the channel, customer type or coupon to see which rules apply.
Dynamic pricing is an option per project, with limits and control by your team.
The software applies the rules you define; we do not promise automatic profit optimisation.
CRM AND LOYALTY
Email marketing: no · Consent is recorded separately from purchases
For points and gift cards we define earning, redemption, expiry and handling after returns, with a history for each transaction.
Customers are not added to marketing communications automatically just because they made a purchase.
RETURNS AND EXCHANGES
Sale #S-1093
| Sold | Returned | |
|---|---|---|
| Run sneakers 42 | 2 | 0 |
| Sport socks | 1 | 0 |
Returned item
Return one item from the sale: once the full quantity is returned, a second return is blocked.
The same quantity cannot be returned twice: the system checks how much has already been returned from the original sale.
The refund and the inventory movement are reconciled with each other.
PAYMENTS AND TILL MANAGEMENT
Till 2 · Shift 1
Balance by currency€

$50
See the balance per currency, then close the shift to compare the expected balance with the count.
The physical till is kept separate from bank accounts and card terminals. Every transaction keeps its original amount and currency; when there is a conversion, the rate and value used are stored too.
Fiscalisation and tax documents are assessed per market and integration. We don’t present the software as fiscally certified without evidence.

Receiving and check
Demand forecasting is treated as a separate function that needs historical data and an assessment of accuracy.

When costs are defined
Sales by channel
Low stock
Sales, receipts and profit are different indicators: a sale may be paid later, and profit needs accurate costs.
Each indicator has a clear formula and source. Values in the views are illustrative.
AI AND AUTOMATION
Prices and availability always come from the relevant source, not from the model. Recommendations respect catalogue constraints.
Models are tested against baseline methods; we do not promise higher conversion or guaranteed accuracy.
STORE NETWORKS AND ROLES
Permissions are enforced in the backend (the system’s server), not just by hiding buttons on screen.

INTEGRATIONS AND MODERNISATION
For each integration we define
What can be developed
We don’t claim to connect with every platform; provider names are used once documentation and terms are verified.
A full rebuild is proposed only after analysis, when it is truly needed.
WORKING DURING OUTAGES
Local functions are designed around the store’s needs. For each project we define:
Card payments and fiscalisation without a connection depend on the provider’s support and the relevant process; we do not promise them without that support.
