Central Studio Proposal for Prinro Building & Steel Merchants

One store, one back office, one source of truth: IQ Retail.

A new Prinro online store and staff back office that read your real stock and your real prices straight from IQ Retail, and send web orders back into it. Hosted in South Africa, and ready for your move to the new ERP in March.

Why changeYour prices are good. Nobody online can see them.

The current store loads everything with JavaScript, so Google and AI assistants like ChatGPT and Grok see an empty page. When we asked an AI assistant for the best round-bar price in Langebaan, it couldn't find a single Prinro price.

Found

Every product page is readable by Google and AI assistants, with price, stock and branch in the page. Ask an assistant for a price, and Prinro can be the answer.

Right price

Each customer sees their own price: retail, trade, key account or contract. The prices come from IQ Retail, so the web price is the counter price.

Into IQ

Web orders and quotes land in IQ Retail as real sales orders and quotes. Nobody types them over.

The live demoClick through it yourself

Everything below is working software at prinro.centralstudio.online. Products and public prices are Prinro's own. Customers, costs, margins and orders are made up, and the stock system is a stand-in until we connect to your IQ Retail.

1

The store

Your own banners, departments, specials and about 60 brands. Pick your branch at the top, and every product shows stock at that branch.

  • Search suggests products, prices and stock while you type
  • Endless "Explore" feed for DIY browsers
  • Works on phones, no app download needed

Every customer sees their own price

Log in as a contractor or key account and the same product shows that customer's price list or contract price. A walk-in buyer sees retail.

Checkout, then straight into the stock system

Address, delivery or collection, payment, review. On a trade account it can go on account. The order is then pushed into the stock system as a sales order with its own document number.

Run the website without a developer

Banners, departments, product titles, photos, specials and announcements. Edit as a draft, preview, publish, and undo if needed. Price, cost and stock stay owned by IQ Retail.

Cost goes up, prices follow

Change a cost in the stock system and every price list and the store reprice on the next sync, with a history of what changed.

How it connectsIQ Retail stays in charge

The store never talks to IQ Retail while a customer is browsing. Your own database, hosted in Johannesburg, copies what it needs from IQ every few minutes and sends orders back. If the IQ server is down, the store keeps selling and the orders wait.

What comes from IQ

  • Products, departments and brands
  • Stock on hand per branch
  • Sell prices, price lists, contract prices and promotions
  • Customer accounts, credit limits and balances

What goes back into IQ

  • Web and telesales orders, as sales orders
  • Quote requests, as quotes

Kerridge confirmed one API serves both IQ Retail and K8 Trader. If the new ERP in March is K8 Trader, this connection carries straight over.

What we buildThree phases

OptionsQuoted separately, when you want them

New ERP connection

When you move in March: connect to the new system. If it is K8 Trader, this may be little or no work. We'll confirm with Kerridge.

WhatsApp ordering

Customers send a list on WhatsApp and get a priced order back to confirm. It's in the demo under WhatsApp.

Plan Drop

Upload a house plan and get a priced materials list. It runs on your own server, so plans never go to the cloud.

A native mobile app is not part of this phase. The store works fully on phones, and we can add an app later.

Before we startQuestions and assumptions

We can quote without these, because we've taken a position on each. These are the answers that could change the number.

Questions

  1. How many IQ companies do you run: one for everything, or one per branch and factory? Each needs its own API licence.
  2. Do your margins and price lists live inside IQ Retail, or partly in spreadsheets?
  3. Is the new ERP in March K8 Trader or K8? It decides whether the IQ connection carries over.
  4. Who looks after your IQ server: your own IT person, or Kerridge support?
  5. Which branch delivers to which town, and what are the fees?

Assumptions we priced on

  • Prinro licenses the IQ API and switches it on. We give your IT or Kerridge the exact list.
  • IQ Retail stays the master for price, cost and stock.
  • Moving from the current store covers products, content and old links.
  • One payment gateway, chosen with you.
  • Prinro owns its domain and its Google accounts.

TermsThe short version

Next stepsThree things to get going

1

Prinro asks Kerridge to license and switch on the IQ Retail API. We send the exact list of what's needed.

2

We start building on Kerridge's IQ test server straight away, so no time is lost waiting.
