Retail runs on thin margins and a lot of data. A mid-size grocer now juggles POS terminals, a loyalty app, an online store and an ERP that may date back to 2009. Consumer goods brands face the same mess one step up the chain.
Below: why companies hand this load to IT partners, what to check before signing, and ten providers worth a look.
Why Retail Tech Keeps Getting Outsourced
Every November the same story repeats. A checkout page that ran fine in October starts timing out under Black Friday traffic. Store IT is no longer a back office. It sits right in front of the shopper.
The pressure comes from several sides:
- ERP deadlines. SAP ends mainstream maintenance for ECC in 2027, so S/4HANA moves sit on most CPG roadmaps.
- AI in daily decisions. Forecasts and markdown pricing are leaving the pilot stage.
- Payment security. PCI DSS v4.0.1 has been fully mandatory since March 2025.
- Unified commerce. Shoppers expect the same stock count in the app and the store.
Most retailers don’t keep a 200-person engineering team. Hiring one takes years. Renting one takes a contract. Sounds logical, right?
Top IT Services Companies for Retail and Consumer Goods
DXC Technology
DXC has served retail clients for decades, and the cases are concrete. Northeast Grocery, parent of Price Chopper and Tops, unified its operations with DXC and reports $40 million in savings. Jollibee Foods relies on it too.
DXC PathWay to SAP S/4HANA targets migration in under 12 months, and a store digital twin modeled queues for a retailer with 5,000+ outlets. More about the service: https://dxc.com/industries/consumer-goods-retail
IBM
IBM stands behind Sterling Order Management, software many large retailers use to route online orders to the nearest store.
When a click-and-collect order says “ready in two hours,” Sterling may have done that math.
IBM Consulting adds SAP and Salesforce work. Remember IBM Food Trust? Walmart used it to trace sliced mangoes in 2.2 seconds instead of a week.
Capgemini
Capgemini, based in Paris, covers everything from strategy to managed services. Its Research Institute publishes a yearly consumer study that retail teams often cite when planning loyalty budgets.
In 2025 Capgemini bought WNS for about $3.3 billion, adding business process operations. For a CPG brand, that means SAP, data and back-office work from one partner.
Deloitte
Deloitte publishes Global Powers of Retailing, an annual ranking of the world’s 250 largest retailers. Each autumn it also releases a US holiday sales forecast the trade press tracks closely.
Deloitte Digital handles delivery: Salesforce Commerce Cloud storefronts, S/4HANA rollouts and loyalty apps. A fit for brands that want advice and execution under one roof.
Tata Consultancy Services
TCS built its own retail software, and that sets it apart. TCS Optumera handles merchandising, assortment and pricing. TCS OmniStore gives staff and online shoppers the same checkout logic.
Delivery runs through large centers in India plus local teams in the UK and US. Runners know the name from the TCS London Marathon and TCS New York City Marathon.
Accenture
Accenture has more than 700,000 employees, the largest headcount here. Its creative arm, Accenture Song, runs campaigns and commerce sites, so a brand gets the ad, the app and the backend from one vendor.
In 2023 Accenture pledged $3 billion to AI, and its AI Refinery, built with NVIDIA, targets forecasting and service agents. Big projects, big budgets. Not for everyone.
Infosys
Infosys brings Equinox, a headless commerce platform for brands that want to change the storefront without touching the order engine. Topaz, its AI suite, covers forecasting and product content.
Delivery is largely offshore, which keeps rates lower. Tennis fans know Infosys as a digital partner of the ATP Tour and Roland-Garros, where its data powers match stats.
Cognizant
Cognizant, headquartered in New Jersey, does a lot of quiet work: store systems, SAP support, data migration. Not glamorous. Still, that’s what keeps a 2,000-store chain running on a busy Saturday.
Its Neuro AI platform helps teams test use cases like demand sensing before scaling. The 2024 purchase of Belcan added engineering capacity for CPG plants.
McKinsey & Company
McKinsey isn’t a classic IT vendor. Its value comes earlier: deciding what to build and why. Periscope by McKinsey, a pricing and assortment tool, helps retailers find margin leaks across categories.
QuantumBlack, AI by McKinsey, then builds models for demand planning. Expect sharp strategy and strong data science, plus a bill to match. Implementation often goes elsewhere.
NTT DATA
NTT DATA, part of Japan’s NTT Group, runs payment systems and store technology on three continents. In Japan it tested Catch&Go, a cashierless store where shoppers grab items and walk out.
It also delivers SAP and Salesforce projects, with data center capacity from the wider group. Retailers wanting hosting and app work in one contract rarely find that combo.
How to Pick the Right Provider
A big logo proves little on its own. Check these instead:
- Retail references in your segment (grocery and fashion are different worlds)
- Certified SAP, Salesforce, Microsoft, AWS or Google Cloud partnerships
- Peak-season track record: ask about a client’s last Cyber Monday
- Security for stores and payments
- A clear pricing model
Final Thoughts
There’s no single winner here. A grocer leaving SAP ECC needs a different partner than a fashion label rebuilding its app.
Global integrators bring scale, consultancies bring strategy, and product-led firms bring ready software.
Start with the problem, not the logo. Ask each shortlisted vendor for two references in your segment and a peak-season plan. Those answers narrow the list fast.
FAQ
What do IT services companies do for retailers?
They build and run e-commerce, POS, ERP, data and security systems, often under one long-term contract.
How long does an SAP S/4HANA migration take?
Usually 12 to 24 months, depending on data volume, custom code and the number of countries involved.
Should a mid-size retailer hire a global integrator?
Not always. Smaller firms can be faster for one project, while global players suit multi-country rollouts.
How is AI used in retail IT today?
Mostly for demand forecasting, markdown pricing, product recommendations and fraud checks at checkout.
