TRUSTED PARTNERS
An off-the-shelf POS works until your menu, your locations or your business model outgrow it. That is where we come in: we build, extend and integrate cloud based POS systems for operators and product companies whose needs a standard subscription cannot meet.
Built Around How You Sell
WHERE POS PROJECTS GET STUCK
Most POS problems are not about the checkout screen. They come from the systems around it: kitchens, delivery apps, inventory, payments, head-office reporting and the internet connection in the building. Here is where we see operators and product teams get stuck, and how we get them unstuck.
Problem
How we solve it
We map how orders really flow through your front of house, kitchen and back office, then build the screens, modifiers, approvals and rules around that, instead of forcing your process into a generic menu.
Fewer workarounds, faster service and shorter training.
Problem
How we solve it
Offline-first terminals that store orders locally, keep the kitchen running over the local network, and sync to the cloud when the connection returns, with payment fallback rules agreed with your processor.
Service continues through an outage.
Problem
How we solve it
Orders from DoorDash, Uber Eats, Grubhub, your website and your app flow into one queue on the POS and kitchen display, with menus and item availability pushed back out from one place.
One order queue and one menu to maintain.
Problem
How we solve it
A cloud back office with real-time sales, labor, inventory and item reports across every location, plus exports to your accounting system, ERP and data warehouse.
Same-day decisions across all locations.
Problem
How we solve it
A migration plan for older MICROS-era terminals: move to Oracle Simphony, to another cloud POS or to a custom system, with menus, reports and integrations carried over and a phased rollout by site.
A planned move instead of an emergency.
Problem
How we solve it
A cost model that compares per-location subscriptions, add-on fees and card processing against a custom build, and a processor-neutral design if you want to negotiate your own payment rates.
A decision based on your numbers, not a sales pitch.
OUR SERVICES
Eight services, one team, from the first workflow review to a POS your team or your customers run every day. Most programs combine several of them.
A cloud based POS system built around your menu, your service model and your locations, on tablets, terminals, kiosks or phones, with a cloud back office your managers can reach from anywhere.
Cloud based restaurant POS systems for quick service, fast casual, full service, bars, cafés, ghost kitchens and food courts, connected to the kitchen and to every ordering channel.
POS for chains, franchises and specialty retail where stock, pricing and promotions must stay in sync across every store and channel.
For software companies, payment providers and franchisors building a POS product of their own: a multi-tenant cloud platform you sell under your brand.
Connect the POS you have, or the one we build, to the rest of your business, so data moves once and nobody re-keys orders.
Modernization for MICROS POS systems and other legacy terminals: migrate to the cloud, or extend what you run today, without a big-bang switch.
Keep your current POS and add what it lacks, using its partner APIs where it offers them.
The operations that keep a cloud POS reliable on the busiest night of the year.
RESTAURANT PLATFORM
Is your restaurant POS cloud based but still cut off from the kitchen, the delivery tablets and head office? In a restaurant, the POS is the hub, but the work happens around it. A cloud based restaurant management system connects ordering, the kitchen, the floor, stock, staff and guests, so every location runs from the same data. We build the modules you need and integrate the ones you already have.
Whether you need one module or all ten, cloud based POS systems for restaurants work best when they share one menu, one guest record and one set of reports. That is the system we design.
BUILD OR BUY
Many businesses do not need a custom POS. Off-the-shelf cloud POS products are good, quick to set up and come with hardware and support. Here is how we advise clients, including when we tell them to buy.
Off-the-shelf cloud POS subscriptions for restaurants run from free entry plans to about $400 per location per month, with kitchen screens and kiosks often billed per device on top, and card processing typically around 2.3% to 2.9% plus 10 to 30 cents per in-person transaction. For a few sites, that is hard to beat. For a group with 25 locations on a $150-per-location plan, software alone is about $45,000 a year before add-ons and processing. That is the point where a custom build, or a custom layer around a standard POS, is worth costing.
MICROS & SIMPHONY
Many restaurants, hotels, stadiums and campuses still run MICROS-era terminals, such as RES 3700, installed years ago. Oracle bought MICROS Systems in 2014, and its cloud POS for restaurants is now Oracle Simphony. If your MICROS POS system is due for replacement, you have three realistic options, and we can help with any of them.
Oracle has announced that from July 1, 2027, the module that sends RES 3700 data to its Reporting and Analytics cloud will be retired, so those reports stop receiving new data.
Oracle retired Enterprise Maintenance Services (EMS), a legacy RES 3700 tool, on July 1, 2026. Sites that used it now maintain menus, prices and taxes inside RES 3700 directly.
Microsoft ended support for Windows 10 on October 14, 2025, and many older POS workstations run it, which adds security and PCI DSS risk.
You buy Simphony through Oracle or its authorized resellers. We build what sits around it: online ordering, loyalty, reporting, labor and data-warehouse integrations, through the APIs Oracle makes available.
We plan the migration, move menus, items, employees and sales history, rebuild your reports and integrations, and roll out site by site.
For groups whose needs no packaged product meets. We design it, migrate your data and run the old and new systems side by side during the pilot.
We are independent: QSS Technosoft is not an Oracle partner or reseller, and we do not sell POS licenses or hardware. That lets us recommend the option that fits, including staying on what you have for now.
Oracle, MICROS and Simphony are trademarks of Oracle and/or its affiliates. QSS Technosoft is not affiliated with, endorsed by or a partner of Oracle.
WHY QSS
Plenty of firms can build a checkout screen. Fewer can make it work offline, connect it to delivery platforms, payments and your ERP, roll it out across many locations and support it on a Saturday night. We are an engineering firm of 250+ that does all of that.
We do not resell POS products, hardware or payment processing, so our build, buy or extend advice is based on your numbers.
See the build vs buy guideLocal order storage, local kitchen routing and conflict-safe sync are designed in from the first sprint, not patched in after the first outage.

A cloud POS that only works with a perfect connection is a liability. We engineer five layers so the store keeps trading when the internet does not.
Offline card payments depend on the payment processor and terminal, for example store-and-forward limits, so we agree them with your processor during design.
PAYMENTS & SECURITY
The safest card data is card data your POS never sees. We design payments so card details are captured by certified terminals and replaced with tokens, which keeps your software out of most PCI DSS scope.
Card data goes from the certified terminal straight to the processor; the POS receives only the result and a token.
Integrations with the processor and terminals you choose, so you can negotiate rates.
Contactless cards, mobile wallets, QR payments and handheld pay-at-table.
Manager approvals for voids, refunds and discounts, with every action logged.
Encryption in transit and at rest, network segmentation and least-privilege access.
Locked-down terminals, remote updates and remote wipe for lost devices.
Alerts for unusual voids, refunds and discounts by employee and location.
Logs, data-flow diagrams and documentation for your PCI DSS assessment.

OUR TECHNOLOGY STACK
Device-agnostic and cloud-agnostic. We recommend what fits your stores, your team and your budget, including tools we don't sell.
The order screen is usually the smallest part of the budget. Offline sync, payments, integrations and multi-location rollout drive most of the cost, so we scope them up front.

Hardware, payment processing, third-party subscriptions and cloud hosting are billed separately. Ongoing maintenance typically runs at a percentage of the build cost each year; we forecast it in your estimate. You leave the discovery call with a range specific to your project.

Answers about cloud POS development: costs, build vs buy, offline mode, payments, MICROS migration, integrations and support.
A cloud based POS system is point-of-sale software that stores its data and settings in the cloud instead of on a server in the back office. Terminals, tablets and kiosks connect over the internet, so menus, prices, reports and updates are managed centrally for every location. A good one also keeps working offline and syncs when the connection returns.
A single add-on module or integration typically costs $14,000–$28,000, a custom cloud POS for one brand across several locations $34,000–$65,000, and a full restaurant management or white-label SaaS POS platform $78,000–$160,000 or more. Hardware, payment processing and hosting are separate. We confirm a range for your scope after a short discovery.
Buy if you run a few locations with standard workflows and want hardware, payments and support from one provider. Build if the POS is your product, your workflows are unusual, your integrations are complex or per-location fees are a large and growing cost. Often the best answer is to extend your current POS with custom modules. The Build or Buy section above explains how we decide.
It depends on your size and service model. For a single restaurant, a mainstream off-the-shelf product is usually the right choice. For groups, franchises and software companies, the best cloud based POS systems for restaurants are the ones that fit your menu logic, work offline, connect to your delivery platforms and accounting, and report across every site. We do not resell any POS, so we can help you compare honestly or build what is missing.
It should. We build offline-first terminals that store orders on the device or an in-store hub, keep printing tickets and routing the kitchen over the local network, and sync to the cloud when the connection returns. Offline card payments depend on your processor's rules, so we agree them with the processor during design.
A cloud based restaurant management system connects the POS with online ordering, the kitchen display system, tables and reservations, inventory and recipe costing, staff scheduling, loyalty, delivery platforms and multi-location reporting, all on one cloud platform with one menu and one set of data.
An integration or add-on module takes 4 to 8 weeks, a custom cloud POS 12 to 20 weeks, and a full restaurant management or SaaS POS platform 5 to 9 months in phases. A pilot site goes live before the wider rollout.
Yes, when it is designed well. We use certified payment terminals and tokenization so card data never touches your POS software, which keeps most of it out of PCI DSS scope. We add encryption, role-based access, audit logs and device management, and we deliver under ISO 27001 and CMMI Level 3 processes.
Yes. We assess your current MICROS POS systems, then help you move to Oracle Simphony (bought from Oracle or its resellers), to another cloud POS or to a custom system, migrating menus, items, employees and sales history and rolling out site by site. Oracle has announced that RES 3700 data will stop flowing to its Reporting and Analytics cloud from July 1, 2027, so planning early helps.
Often, yes. For Simphony, we build online ordering, loyalty, reporting and labor integrations through the APIs Oracle makes available to your account. For an older MICROS POS system, options are more limited, and we will tell you after an assessment whether integration or migration makes more sense. QSS is not an Oracle partner or reseller.
Yes. Orders from delivery platforms can flow straight into the POS and kitchen display, with menus and item availability synced back. Each platform requires its own API approval and certification for production access, which we plan into the timeline.
We integrate with the processor and terminals you choose, through their certified SDKs and semi-integrated terminals, and with standard peripherals such as receipt and kitchen printers, cash drawers, barcode scanners, scales and kitchen screens. We confirm the exact devices and processor during discovery.
Yes. We build multi-tenant cloud POS platforms that you sell under your brand, with merchant onboarding, subscription billing, an admin console, partner APIs and branded apps. You own the code and the product.
Yes, if your POS offers APIs or a partner program. Common additions are loyalty and gift cards, branded ordering apps, delivery-order hubs, labor tools and cross-location reporting.
Yes. As an Odoo partner, we configure Odoo Point of Sale and connect it to Odoo inventory, accounting and e-commerce, or to a custom front end where Odoo's standard screens do not fit.
Expect cloud hosting, payment processing, any third-party subscriptions and ongoing maintenance for updates, security patches and new features. We include a yearly running-cost forecast in every estimate, so you can compare it with subscription pricing.
You do. Code, designs, data models, documentation and all business and customer data are yours, with no license fees to QSS and no lock-in.
We start with one pilot site, run the old and new systems side by side where needed, train staff by role, cut over in a quiet period with a rollback plan, and then roll out site by site with support on call during the first busy shifts.
