Warehouse and Sales Software in One
Warehouse and sales software is one system where stock, POS, orders, invoices and couriers run on the same record, with no double entry. We build a custom solution where every sale deducts stock in real time, issues a compliant invoice and creates a courier label — no Excel between modules and no two separate licenses for warehouse and till.
What the system includes
The solution merges the warehouse and sales modules into one backend on your own database. No monthly per-seat subscription and no manual reconciliation between two disconnected programs.
- ✓Real-time stock — multi-warehouse view, minimum-level alerts, lots and serial numbers, goods receipt and automatic deduction on every sale.
- ✓POS and order processing — a till for store or office sales, barcode lookup, partial payments, per-client discounts and a unified order history across online and in-store.
- ✓Compliant invoicing — proforma, invoice, credit and debit notes with correct numbering, VAT groups and export to your accounting software.
- ✓Courier integration — one-click labels for Speedy and Econt, cash on delivery, return receipts and automatic shipment status tracking.
- ✓Barcode scanning — receiving, stock counts and dispatch with an Android phone or industrial scanner, no manual counting and no quantity mismatches.
- ✓Customers and pricing — customer card, price groups, credit limits, deferred payment and full purchase history per account.
- ✓Reports and dashboard — turnover by product, margins, slow movers, stock value and daily Z-report, exportable to Excel and BI.
- ✓Role-based access — warehouse, cashier, salesperson and manager see only their functions; every movement is logged with user and time.
Who it is for
A distributor with 3000+ items and dozens of credit customers. A rep takes an order from the field, the system checks stock and credit limit, reserves goods, issues an invoice and pushes a courier label — the full order-to-dispatch cycle in one system in under a minute.
A physical shop plus an online store sharing one warehouse. Till sales and website orders deduct from the same quantities, so you never sell stock that is already gone. Courier cash on delivery is matched automatically against the issued invoice.
A small producer holding finished-goods stock and selling directly to dealers. Lots and serials are traced from receipt to customer, and reports show which products carry real margin and which sit idle over 90 days.
How we build it
We are not a box reseller. We build business software where warehouse and sales are designed together from day one, on your own database, with full control over data and logic.
1. Map the order-to-dispatch process
We map the real path of goods and money — receiving, put-away, till or rep sales, invoicing, dispatch and returns. We pinpoint the double-entry and error points your current programs create and lock down which integrations (accounting, couriers, online store) are mandatory in the first release.
2. Model warehouse and sales together
We design a single data model where item, stock, order, invoice and shipping label are linked records, not separate tables in two systems. We define warehouses, units, VAT groups, pricing policies and reservation rules so every movement is traceable to user and time.
3. Build modules and integrations
We build the warehouse module, the POS, invoicing and admin panel, then connect Speedy and Econt couriers and the accounting software via API integrations. If you run an online store (WooCommerce, Shopify, OpenCart) we sync stock and orders both ways so you never oversell.
4. Migration, training and go-live
We migrate the catalog, opening stock and accounts from old programs with balance control, train warehouse, cashier and sales staff by role, run the new system in parallel with the old one for 1-2 weeks and only then retire the legacy tools — with no break in sales.
5. Support and evolution
After launch we monitor errors, optimize slow queries and add new reports and integrations in sprints. The code and database are yours — no vendor lock-in and no per-user or per-document fees.

Frequently Asked Questions
Why is warehouse and sales software better than two separate programs?
When warehouse and till are two programs, every sale is entered at least twice and stock drifts apart by end of day. In a combined system the sale automatically deducts quantity, issues an invoice and creates a courier label on one record. The result is up to 70% less manual work and no mismatch between what the till shows and what is actually in stock.
How much does it cost and are there monthly fees?
A combined warehouse + sales module with invoicing and courier integration starts from €5,400 as a one-off build. More complex setups with multi-warehouse, online-store sync and a B2B portal are quoted by scope. There is no per-user or per-document subscription — you pay only hosting and optional support, typically €60-€180 per month.
Can it connect to couriers and accounting software?
Yes. We integrate Speedy and Econt for labels, cash on delivery and tracking, plus invoice export to your accounting software. If you run an online store on WooCommerce, Shopify or OpenCart, we sync stock and orders both ways so the warehouse is a single source of truth across channels.
Can we migrate data from our current programs?
Yes. We migrate the catalog, opening stock, prices and accounts from Excel or your old warehouse/POS software with balance control. We run the new system in parallel with the old one for 1-2 weeks to reconcile quantities, then retire the legacy tools — with no interruption to sales.
Who owns the code and data?
Entirely yours. You get the source code, the database and the documentation. No vendor lock-in, no limit on users or documents, and you can host with us or on your own infrastructure.
