Your store, inventory, and online sales should work together.
Running a retail business means managing products, inventory, sales, employees, customers, and orders across different systems and locations. Develop & Conquer builds custom software, POS integrations, mobile apps, and automation that connect your storefront, online sales, inventory, and back-office operations so you can spend less time managing disconnected systems and more time growing your business.
Know what you have, where it is, and what's already been sold.
A product may be listed on Shopify, sold at a Square register, held at another store, and tracked in an inventory platform. When those systems aren't connected correctly, staff may not know what's actually available to sell.
| Location | On hand | Reserved | Available |
|---|---|---|---|
| Sacramento store | 22 | 3 | 19 available |
| Roseville store | 14 | 2 | 12 available |
| Online channel | — | 1 | Sells from pooled stock |
| Warehouse | 12 | 0 | 11 available |
Illustrative data. Sales, reservations, returns, and transfers update inventory according to the connected platforms' synchronization rules. We don't promise every system updates instantly, some use webhooks, scheduled sync, or delayed processing, so the implementation accounts for failed updates, duplicate events, refunds, and reconciliation. We build inventory synchronization, SKU mapping, multi-location visibility, transfers, reservation tracking, low-stock notifications, and custom inventory apps.
A sale should update more than the register.
In-store checkout and online orders don't operate in a simple sequence, one transaction shares information in several directions at once. A connected layer fans it out to the systems that need it.
Conceptual integration. Each update depends on the source system, permissions, and reconciliation rules. We build POS-to-inventory integrations, transaction data synchronization, refunds and returns workflows, customer record matching, and accounting connections, including flagging a failed synchronization for review rather than assuming every update succeeds.
Let customers shop the way that's convenient for them.
A customer checks local availability online, buys the product, chooses pickup, and gets a notification when it's ready. Order #10482, Everyday Canvas Tote, Sacramento store pickup:
- 1
Order received
The online order comes in and is matched to the pickup location.
- 2
Inventory allocated
The item is reserved against that store's stock so it isn't oversold.
- 3
Staff prepared order
A team member picks and stages the order for pickup.
- 4
Customer notified
An approved notification tells the customer it's ready.
Illustrative order; no actual purchase or notification. We build store pickup workflows, inventory allocation, fulfillment dashboards, pickup notifications, order status pages, and supported e-commerce integrations. For online-only operations, see our e-commerce work; this page stays focused on businesses with physical storefronts.
Know what needs to be reordered before the shelf is empty.
A retailer needs to understand what's selling, what's running low, what's already on order, and what's expected to arrive, before placing the next order.
| Product | Available | Recommendation |
|---|---|---|
| Canvas Tote | 8 | Review reorder |
| Ceramic Mug | 34 | Sufficient |
| Travel Bottle | 5 | Review reorder |
| Wool Beanie | 61 | Sufficient |
We build low-stock alerts, supplier records, purchase order workflows, receiving tools, barcode scanning, stock transfers, and reorder recommendations.
Your shelves, displays, scanners, and systems can work together.
Digital price displays
Connect compatible electronic shelf labels or digital signs with approved product and promotional data.
Barcode & inventory tools
Build scanning and receiving workflows connected to your inventory system.
Customer kiosks
Create supported product lookup, customer check-in, or self-service experiences.
Connected digital signage
Manage approved promotions, product information, and display content from connected business systems.
Software doesn't have to stop at the computer, we can help connect compatible equipment and displays to the information your business already uses. See our connected hardware work. We don't imply universal compatibility with payment terminals, electronic shelf labels, or proprietary POS hardware; those integrations require individual evaluation.
Recognize returning customers, wherever they shop.
Customer accounts
Purchase history and preferences that stay consistent in-store and online.
Loyalty & rewards
Loyalty integrations, gift card balances, and rewards tracking across channels.
Approved communication
Keep the relationship consistent without turning it into a stream of promotions.
A customer might buy in-store, browse online, return at another location, or redeem an eligible reward. The value is a consistent experience across channels when the systems support it, more than sending additional promotional messages.
See what's selling, where it's selling, and what needs attention.
Example data only. Actual reporting requires consistent treatment of refunds, discounts, taxes, and transaction dates. For multi-location businesses we can add product-level profitability and inventory turnover where cost and stock data are reliable.
Keep the systems you like. Connect the ones that don't talk.
Shopify + POS
Keep authorized product, order, and inventory information connected.
Square + inventory
Use supported catalog, order, and inventory APIs for custom workflows.
POS + QuickBooks
Coordinate supported financial data without treating a sale as a bank deposit.
Inventory + barcode scanner
Build custom receiving, transfer, and counting workflows.
Product catalog + digital displays
Update compatible displays using approved pricing and promotional information.
Online + in-store
Connect channels so availability and orders stay coordinated.
We start with the software and equipment your business already uses, evaluate available APIs, vendor permissions, and existing connections, then build the integrations or custom applications that make sense. Some vendor systems simply don't provide the necessary access, so we confirm before promising it.
Turn your sales and inventory information into useful answers.
Rather than a generic chatbot, ask questions about your business using authorized sales and inventory data, grounded in trusted records with approval required for consequential changes.
Illustrative AI experience, not an analysis of actual retail data. Responses stay grounded in trusted business records, maintain permissions, and require approval for consequential changes.
Different retail operating models. Connected systems.
Independent retailers
POS, inventory, loyalty, and online sales in one connected setup.
Multi-location stores
Stock transfers, reporting, purchasing, and consistency across stores.
Specialty & lifestyle retail
Product catalogs, customer accounts, and digital displays.
Retailers selling online
Connected orders, pickup, fulfillment, and inventory.
Retailers with wholesale accounts have strong custom-software opportunities too, wholesale pricing, inventory allocation, and B2B ordering often need more than an off-the-shelf POS provides.

Retail software and integrations, answered.
Can you connect Shopify with our existing retail POS?
We can evaluate your POS platform, Shopify's supported APIs, and available integration options to determine the best approach.
Can inventory update automatically after an in-store sale?
Yes, where supported. The integration should account for synchronization timing, inventory reservations, returns, and failed updates.
Can you build a custom inventory management app?
Yes. We can develop applications for inventory lookup, stock counts, barcode scanning, transfers, and other workflows.
Can you connect multiple store locations?
Yes. We can evaluate ways to connect inventory, reporting, purchasing, and supported customer information across locations.
Can you build a buy-online, pick-up-in-store experience?
Potentially. We can build or integrate store pickup workflows where the relevant e-commerce, inventory, and fulfillment systems support them.
Can you connect our POS to QuickBooks?
We can evaluate supported connections for sales, refunds, taxes, fees, and other financial information while preserving appropriate accounting reconciliation.
Can you connect digital price tags or signage?
Yes, where the hardware and software provide compatible, authorized interfaces.
Can AI help us understand our retail sales?
AI can help summarize and query approved sales and inventory information, with appropriate controls and validation.
Do we need to replace our POS?
Usually not as a first step. We start by evaluating the software you already use and whether integrations or custom extensions can address the problem.
