I need a custom point-of-sale solution that keeps my retail store, WordPress site, and countertop POS terminal working as one. The goal is to enter a product or complete a sale in any channel—online or in-store—and have inventory levels update everywhere within seconds. Core requirements • Inventory management must sync bi-directionally so web orders instantly deduct in-store stock and vice-versa. • Robust sales reporting that lets me filter by location, product category, date range, and payment type. • Payment processing has to accommodate both cash and cards at the physical register while continuing to accept card payments online. Integration details My website runs on WordPress, so the POS back end can extend WooCommerce, tap into its REST API, or use a custom plugin—whichever achieves real-time data flow without slowing checkout. The hardware side should print receipts, open the cash drawer, and read chip/tap cards through a gateway that supports PCI compliance. Deliverables 1. Fully functioning POS application installed on one Windows terminal (with clear instructions so I can replicate it on additional machines). 2. Custom WordPress plugin or API integration that keeps products, orders, customers, and stock synchronized. 3. Dashboard reports exporting to CSV/PDF. 4. One-hour walk-through video plus concise setup documentation. Acceptance criteria • A test sale in store and a test order online each update inventory within 30 seconds. • Reports match totals in both environments. • No duplicate SKU creation after 200+ transactions. If this aligns with your skill set, let’s confirm milestones and timeline so I can get the system live before our next stock arrival.

Real-time inventory sync between WooCommerce and a physical register sounds simple on paper, but the risk is usually in transaction timing, duplicate SKU logic, and hardware/gateway compatibility on the Windows terminal. I’d approach this by first locking down the current POS hardware/payment stack, then mapping whether the cleanest route is a WooCommerce plugin extension or a lightweight middleware layer for fast stock/order updates. I’ve worked on WordPress/WooCommerce customizations, API-based sync jobs, reporting dashboards, and checkout/payment related workflows where data consistency matters more than just “connecting systems.” For your case, the important part is not only syncing sales, products, and customers, but making sure reporting totals stay reliable after repeated transactions and that checkout speed is not hurt. To make this practical, I can also provide clear replication notes for extra terminals. - Which countertop POS terminal, receipt printer, cash drawer, and card reader/gateway are you using now? - Do you already have an in-store POS software in place, or do you want the Windows terminal app built around WooCommerce from scratch? - How many products/SKUs and store locations are involved at launch?

Hi, I hope you're doing well! This is a well-scoped project and I'm confident I can build exactly what you need. Here's my approach: Real-time sync via WooCommerce REST API between your Windows POS and WordPress store, updating inventory both ways within seconds. Custom plugin handling products, orders, customers, and stock with no duplicate SKUs. PCI-compliant payment gateway supporting chip/tap cards and cash drawer at the register. Dashboard with CSV/PDF exports filtered by location, category, date, and payment type. A few questions to move forward: 1. Do you have a preferred payment gateway already, such as Stripe or Square, or are you open to recommendations? 2. What's your target go-live date, and do you have an existing WooCommerce setup or will this be built fresh? 3. How many product SKUs are currently in your catalog, and do you use any existing inventory tool we'd need to migrate from? Let's get this live before your next stock arrival! Azeem Amin

Hi, When you say inventory needs to sync within seconds, does that mean real-time push updates, or is polling every few seconds acceptable for your workflow? I've built WooCommerce inventory systems and POS integrations before, so I can handle the bi-directional sync and reporting piece. The budget and days shown here are just a starting point—once we nail down whether you need true real-time or near-real-time, I'll give you an actual number. Regards, Nurul Hasan

Hello, You need one system to control store, WordPress, and POS without inventory drift , that hidden sync gap is the real risk here. I’ve built WordPress and WooCommerce integrations, custom PHP/MySQL plugins, REST API sync, and business dashboards, so I can connect sales, stock, customers, and reporting into one reliable flow. For the terminal side, I can structure the POS to handle receipts, cash drawer, and PCI-friendly card processing while keeping checkout fast and data consistent. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’d start by mapping the sync rules, then build and test the inventory, sales, and reporting layers before deployment on the Windows terminal. Which POS hardware, receipt printer, cash drawer, and payment gateway are you using for the terminal? Best regards, Asad

Your WordPress retail POS needs a reliable single inventory source, not a loose import/export process. I can build this around WooCommerce with a custom plugin and a Windows POS application, synchronizing products, SKUs, customers, orders, and stock through authenticated REST endpoints. Each transaction will use idempotency keys and SKU-based matching to prevent duplicate products, including the 200+ transaction acceptance test. I’ll implement near-real-time stock updates in both directions, with webhook/event handling, retry logic, and conflict protection so online orders deduct store inventory and register sales update WooCommerce within 30 seconds. The register will support cash and card payments through the selected PCI-compliant gateway, plus receipt printing and cash-drawer control where supported by its Windows/USB SDK. Reports will filter by location, category, date, and payment type, with CSV/PDF export and totals reconciled against WooCommerce orders. I’ll install and test the first Windows terminal, provide replication instructions, concise setup documentation, and a recorded one-hour walkthrough. My relevant experience includes SwiftKhata, a web/desktop/mobile POS and inventory platform, plus custom WooCommerce and WordPress order systems. I’ll confirm milestones after reviewing your terminal and gateway details. Muhammad Saad

The hard part here isn't the till screen — it's making sure two channels never sell the same last unit, so I'd make WooCommerce the single source of truth for stock and have the Windows POS write through it: sales post via the Woo REST API with atomic stock adjustment, and a custom plugin fires webhooks back so the terminal updates in seconds, with a local SQLite queue that keeps you selling if the internet drops and reconciles on reconnect. Hardware side I'll drive the receipt printer and cash drawer kick over ESC/POS, and use a semi-integrated card terminal (Stripe Terminal or similar) so card data never touches your PC and your PCI scope stays minimal. Reports come from one query layer filterable by location, category, date and tender, exporting CSV/PDF. I build POS software in .NET for Windows regularly and can start immediately.

Hi, I've built WooCommerce integrations before, including a WordPress and WooCommerce setup for financial products where product data and orders had to stay in sync through the REST API. That bi-directional sync you need is the hard part here. The safest route is a queue-based sync so a web order and an in-store sale never race each other on the same SKU, with each transaction reconciled against a single source of truth to avoid duplicates after your 200+ transaction test. One question: which card gateway and receipt/drawer hardware are you already running, or is that open? That decides how the Windows terminal talks to WooCommerce. WordpressWoocommerce: from a financial products integration. Since we've not worked together, I'd start on a milestone so you release only on delivered work. Adil
