Points of sale, e-commerce and retail IT solutions
Arke Technologies designs, integrates and supports points of sale, online stores and retail IT solutions for multi-store retailers and online sellers across South Africa. From Johannesburg, we connect tills, e-commerce, ERP and accounting systems, secure payments and customer data under POPIA, and run store IT under one service-level agreement.
Points of sale: what a retail POS system does
Points of sale are where a retail business meets its customers and its data: every scan changes stock, revenue, VAT and often a loyalty record. A POS system combines hardware (terminal, scanner, printer, cash drawer and card machine) with software that records sales, applies prices and promotions, manages stock and reports to head office.
In IT terms, a retail store is a set of points of sale, a back office and a network linked to head office, whether a mall shop or an internet shop business with no counter at all. Retail management means running stock, pricing and customers across all of them, so an integrated POS system shares one stock pool and price list with the online store, ERP and accounting. That integration, more than the till, decides whether retail IT solutions work.

Point of sale system for a small business, or for a chain
A point of sale system for a small business can be a tablet app and a card machine, paid monthly. A chain needs central price and promotion control, stock transfers, role-based access and reporting by store. The opposite of bespoke software is off-the-shelf software, and most retailers are best served by off-the-shelf software that is well integrated.
| Option | Suits | Watch for |
|---|---|---|
| Off-the-shelf POS, by subscription | Standard retail flows and a fast start | Per-till fees, limits on data export and integration |
| Off-the-shelf POS plus integration | Chains that need POS, online store, ERP and accounting in step | Clear ownership of stock and price data; tested connectors |
| Custom POS software development | Unusual pricing, trade counters, offline stores or workflows products cannot handle | Specification, testing, card-payment scope and long-term support |
When no packaged product can do the job, we build custom POS software as custom software, working offline when the line drops, with card payments kept on the provider's certified terminal or hosted page. Retail software developers who put card data on your servers bring you into PCI DSS assessment scope; we design to avoid that.

Point of sale software for pharmacy
POS software for a pharmacy must handle dispensing, prescriptions, scheduled medicines and stock with expiry dates. For South African pharmacies, see IT for healthcare and pharmacy.

E-commerce and ERP integration
E-commerce ERP integration keeps the store and the ERP in step: products, prices and stock flow out; orders, customers and payments flow back; dispatch status reaches the customer, and nobody re-keys an order. B2B e-commerce ERP integration adds customer price lists, credit limits and account terms, so the ERP, not the store, owns pricing.
Shopify ERP integration is a common case: connectors exist for SAP Business One (the SAP B1 Shopify integration), Dynamics 365 Business Central, NetSuite, Odoo and Acumatica (an Acumatica Shopify integration), and other systems use a Shopify API integration or an e-commerce integration platform (middleware), as a Shopify SAP integration usually does. A POS system e-commerce integration, whether a Lightspeed Shopify integration, Shopify's own POS or another till, gives both channels one stock pool through the vendor's POS integration API or a POS system integration in middleware. Shopify CRM integrations with HubSpot, Salesforce or Zoho carry order history into CRM. Four questions decide every project:
01.
Which system is the master for product, price, stock and customer records.
02.
How fast data must move
real-time for stock and orders, batched for heavy updates.
03.
What happens on failure
retries, queued messages and alerts, so no order is lost.
04.
Who owns the connector after go-live, and how changes are tested before a sale weekend.
Product data needs the same care: retail packaging, the unit a shopper buys with its own barcode, differs from the supplier's carton. Price gaps between channels invite retail arbitrage, in which resellers buy underpriced stock in bulk to resell on marketplaces; one master price list closes the gap.
Shopify, Xero and Sage: accounting integration
Shopify accounting software in South Africa usually means Xero, Sage or QuickBooks, and the integration matters more than the logo.
| Accounting system | Typical integration route | What to decide first |
|---|---|---|
| Xero | A connector app or the Xero API; POS products that integrate with Xero | Summary or per-order posting; which system owns stock |
| Sage Business Cloud Accounting (formerly Sage One), Sage 50 | A connector app or the product's API, depending on product and version | Chart-of-accounts mapping, VAT codes, stock items |
| Sage 200, Sage 300, Sage X3 | Mid-market ERP connectors or middleware | Multi-warehouse stock, customer price lists, approvals |
| SAP Business One, Dynamics 365 Business Central, Odoo, NetSuite, Acumatica | An ERP connector or middleware | As above, plus B2B pricing and credit control |
Shopify integration with Xero. Post a daily payout summary, with sales, gateway fees, refunds and VAT on separate lines, rather than one invoice per order, so your accountants can reconcile it to the bank. For a Shopify Xero inventory integration, note that Xero's inventory tracking is basic; the stock master usually sits in Shopify, the POS or an inventory system.
Xero POS integration. Xero sells no point of sale of its own, so a Xero POS system is a POS product that integrates with Xero; the best POS system for Xero posts takings, card settlements and VAT correctly. Xero point of sale integration and Xero e-commerce integration should share one chart of accounts.
Shopify Sage integration. An e-commerce Sage integration depends on the product: a Shopify Sage 50 or Shopify Sage One integration is usually a connector job, while a Shopify Sage 200, Sage 300 or Sage X3 integration meets a mid-market ERP with multi-warehouse stock. We scope each on your product and version; see ERP and accounting integration.
Payments: e-commerce payment gateway integration
E-commerce payment integration connects checkout to a gateway, and settlements back to accounting. We integrate PayFast, Yoco, Paystack, Peach Payments and Stripe. Shopify payment gateway integration is different: a store can use only the third-party providers Shopify lists for its country of registration, so a Stripe Shopify integration or PayU Shopify integration depends on that list, and we confirm it, with Shopify's charges, before you apply. E-commerce payment gateway integration on a custom site uses hosted payment pages or tokenisation, so card numbers never touch your servers. See payment gateway integration.

Retail security management
Retail security management protects card payments, customer data and trading hours. The managed security services value proposition is automated monitoring, a tested response plan and evidence for the board, without building an in-house security team.
Tills on their own network: POS, back office, cameras and guest Wi-Fi segmented behind firewalls. The purpose of network monitoring is to catch an outage or unusual traffic before trading suffers.
Vulnerability assessment: its purpose is to find and rank known weaknesses in stores, websites and cloud accounts before attackers do; see cybersecurity assessment.
Penetration testing: we scope and perform tests on online stores and store networks. A positive pen test, one that finds an exploitable weakness, gives you evidence to act on; we help remediate it and retest.
Cloud security posture: cloud security posture management compares AWS, Azure or Google Cloud settings with a secure baseline, and posture monitoring catches drift.
Customer data under POPIA: electronic direct marketing to people who are not yet customers needs their consent; see POPIA compliance.
Retail IT services and support across stores
Retail IT support follows trading hours. Our retail IT services cover the service desk for stores and head office, remote support on our own platform with every session approved and logged, POS terminal and device management, store Wi-Fi, and business fibre with LTE backup through Fibre Boyz. Monitoring checks each managed computer every 15 minutes and logs faults as tickets automatically. Our office hours are Monday to Friday 08:00–17:00 and Saturday 09:00–13:00 (SAST); cover for late trading, Sundays and public holidays is agreed in your SLA.
Peaks are predictable: Black Friday, the festive season, and the back-to-school rush in January, when families buy uniforms and stationery and school-leavers apply for university or register to upgrade their matric results. We freeze changes around your trading calendar. Servers, networking and computers come through Server Hub. Customer service teams need e-commerce helpdesk software joined to the store and CRM, and an AI assistant, where it helps, runs in modes you control: off, draft with staff approval, or automatic. See chatbots and conversational AI.

Governance, data and compliance
The purpose of IT governance is to make technology spend, risk and data serve the strategy, provably. Retailers answer to boards rather than government procurement rules, and it is possible to have governance without government oversight: King IV Principle 12 makes technology and information governance a board responsibility, and the JSE Listings Requirements expect listed companies to report how they apply King IV.
An SLA set to trading: incidents prioritised P1 (critical outage) to P4 (low-impact request), with response and resolution targets agreed to the impact of downtime, escalation paths, and a monthly service review and report.
Documentation you own: an enterprise architecture repository recording each system, what each integration exchanges and who owns it.
Data you can trust: a retail data warehouse whose metadata repository defines each measure (a sale, a return, like-for-like growth), so Power BI reports agree; retail audit software for store visits and stock counts can feed it.
Compliance: POPIA for customer and loyalty data; King IV Principle 12; card data kept on the payment provider's certified systems to limit PCI DSS scope; controls aligned with ISO/IEC 27001 and the NIST Cybersecurity Framework (alignment, not certification).
Procurement: Level 1 B-BBEE contributor, giving 135% procurement recognition (sworn affidavit available on request); company documents, CSD supplier number and SARS tax compliance status on request; buy through a proposal and SLA, or a purchase order.
Continuity: you own your data, credentials and documentation, and at handover or exit we transfer all of it.

Frequently asked questions
What is a point of sale system? Show answer Hide answer
A point of sale (POS) system is the hardware and software a retailer uses to complete sales: a terminal or tablet, scanner, printer and card machine, with software that records each sale, applies prices and promotions, updates stock and reports to head office. In a modern retail business, points of sale also share stock and prices with the online store, ERP and accounting system.
What is the best point of sale system for a small business? Show answer Hide answer
The best point of sale system for a small business is usually an off-the-shelf subscription POS that handles your products, integrates with your accounting software and exports your data if you leave. Check card-machine fees, offline operation during load-shedding, stock features and support hours. Custom software rarely pays off at that size; integration with Xero or Sage usually matters more.
How do I integrate Shopify with Xero? Show answer Hide answer
Shopify integrates with Xero through a connector app or through the two platforms' APIs. For most stores, post a daily payout summary to Xero, with sales, gateway fees, refunds and VAT on separate lines, rather than one invoice per order, so the bank reconciles cleanly. Decide first which system owns stock: Xero's inventory tracking is basic, so the master usually sits elsewhere.
Can Shopify integrate with Sage? Show answer Hide answer
Yes. The route depends on the Sage product: Sage 50 and Sage Business Cloud Accounting use connector apps or their APIs, while a Shopify Sage 200 integration, or one with Sage 300 or Sage X3, connects to a mid-market ERP and usually needs middleware. We scope each integration on the product and version you run, mapping VAT codes, stock items and customer accounts.
What is the purpose of a vulnerability assessment for a retailer? Show answer Hide answer
The purpose of a vulnerability assessment is to find and rank known weaknesses in your stores, website, cloud accounts and devices before attackers do, so fixes go where the risk is highest. For a retailer that means points of sale, store networks, the online checkout and supplier access. A penetration test then goes further, proving whether a weakness can actually be exploited.
Is custom POS software worth it? Show answer Hide answer
Custom POS software is worth it only when packaged products cannot handle your pricing, workflows or offline needs, and that gap costs more than building and supporting your own system. For most retailers, an off-the-shelf POS integrated well with the online store, ERP and accounting system is the better investment. When custom is right, keep card data on the payment provider's certified systems.
