How to Run a Flat-Glass Business: From Quote to Install

1. Why Flat Glass Is Different

Most trades buy finished products and resell or install them. A flat-glass business manufactures. Every shower screen, splashback, balustrade panel or window pane is cut to a specific size, processed to a specific specification and delivered to a specific site. That creates four problems generic business software rarely handles well:

• Made-to-measure stock. Once a panel is cut, it belongs to one job. A wrong measurement can't be returned. It becomes a remake.
• Irreversible processing. Toughened glass cannot be cut, drilled or edged after toughening, so every hole, notch and edge has to be right before the panel goes into the furnace or out to your toughening supplier.
• Fragile logistics. Panels travel on A-frames and stillages, need careful handling and are easy to damage between the factory and the site.
• Mixed customers. The same business might serve walk-in retail customers, trade installers on account and commercial builders with progress claims, each with different pricing and payment terms.

2. The Flat-Glass Job Lifecycle

Almost every glass job, from a single mirror to a commercial shopfront, moves through the same eight stages:

1. Enquiry and site measure: capture the customer, the site, access, and measurements, ideally with photos.
2. Quote: price the glass, processing, hardware, delivery and installation (see pricing).
3. Order confirmation and deposit: lock in the final sizes and specification, and take a deposit for custom work.
4. Purchasing: order stock sheets, toughened or laminated panels from a processor, aluminium sections and hardware.
5. Production: cut, edge, drill, notch, then toughen, laminate or assemble double glazing (IGUs) as required.
6. Quality check and racking: check sizes and edges, label each panel and rack it by delivery run.
7. Delivery and installation: deliver, install, and get a signed proof of delivery.
8. Invoice and collection: invoice, chase overdue accounts, and manage retentions on commercial work.

Problems compound from left to right. A measurement mistake at stage 1 isn't found until stage 7, after the glass, processing and a truck run have all been paid for. The fix is simple to describe and hard to do on paper: one record per job that every stage works from.

3. How to Price Glass Jobs Accurately

Underpricing in glass rarely comes from the glass itself. It comes from the extras that weren't counted. A complete glass price usually builds up from these drivers:

Two habits protect margins. First, keep one price matrix: standard product prices plus customer special pricing for each trade account, so every quote starts from the right number instead of a salesperson's memory. Second, follow up every quote within a few days. In a made-to-measure trade, the business that follows up first often wins.

4. Safety Glass and Australian Standards

In Australia, the National Construction Code (NCC) references a set of Standards Australia documents for glazing. The three every glass business should know are:

• AS 1288, Glass in buildings: Selection and installation. Sets out how to select glass for a location, including human impact safety requirements for areas such as doors, side panels, low-level glazing, bathrooms and balustrades.
• AS/NZS 2208, Safety glazing materials in buildings. Covers testing and classification of safety glazing materials, such as Grade A toughened and laminated glass.
• AS 2047, Windows and external glazed doors in buildings. Applies to window and door manufacturers, covering performance such as structural strength and water penetration resistance.

In practice, that means two things for your systems. Record the glass type and grade on every order line, and print it on the panel label, so you can show what was supplied for each location. And keep the processing order right: toughened glass is roughly four to five times stronger than annealed glass of the same thickness, but every hole and edge must be finished before toughening. Laminated glass holds together when broken because the panes are bonded to an interlayer. Heat-soak testing reduces the risk of spontaneous breakage in toughened glass caused by nickel sulphide inclusions.

This is general information, not compliance advice. Always check the current edition of each standard and the NCC requirements for your project.

5. Production, Processing and Panel Labels

The production floor is where glass businesses either make or lose their margin. Three practices make the biggest difference:

• Schedule by processing route, not by order. Group panels that need the same edgework, drilling or toughening run, then release them to dispatch by delivery date.
• Label every panel. A good glass label carries the customer, job or order number, panel size, glass type, processing notes, delivery run and a barcode. It is the panel's identity from the cutting table to the site.
• Record every remake. Log the reason (measurement, breakage, processing error, transport damage). A remake rate you don't measure is a cost you can't reduce.

6. Stock, Offcuts and Purchasing

Glass inventory isn't just sheets on a rack. Fabricators carry stock sheets in standard and jumbo sizes (jumbo float is commonly 6000 × 3210 mm), reusable offcuts, toughened panels bought in from processors, aluminium sections, hardware and sealants. Knowing what is on the rack, and what is already allocated to jobs, prevents both emergency orders and dead stock. Raise purchase orders against the jobs that need them, so the cost of bought-in toughened or laminated panels lands on the right job.

7. Delivery and Installation

Plan delivery runs by area and by rack, not by the order in which jobs were sold. Confirm site access the day before, and track A-frames and stillages so they come back. A signed proof of delivery protects you when a builder later disputes a chipped edge. Installers should be able to see the job notes, panel list and site contact on their phone.

8. Cash Flow: Deposits, Progress Claims and Debtors

Custom glass is paid for by the business long before the customer pays. Protect cash flow by taking deposits on made-to-measure retail work, invoicing on delivery or completion, and running progress claims on commercial jobs under your state's security of payment legislation. Review your debtors list every week, set credit limits for trade accounts, and put accounts on hold before the balance becomes a bad debt.

9. Seven KPIs Every Glass Business Should Track

10. Signs You've Outgrown Spreadsheets

• The same job is typed into a quote, an order sheet, a cutting list and an invoice.
• Only one person knows the special prices each trade customer gets.
• You find out about a remake when the customer calls.
• Nobody can say, today, which jobs are waiting on toughened glass from your supplier.
• Quotes go out and are never followed up.
• Month-end takes days because sales, stock and accounts don't agree, and invoices are typed into the accounting package by hand.

Infinity2X GlassOne was built around this lifecycle. Each stage maps to a module, and every module shares one database, so the job is entered once:
