Kerf turns your range into a 3D configurator your customers actually use. They pick the size, the finish, the handles — and see the price and your cut list update as they go. You get the enquiry with the spec already written.
The problem
A customer asks for a price. Someone measures, someone draws, someone rebuilds the costing in a spreadsheet. Days pass. Meanwhile the customer has asked two other people and the fastest quote usually wins — not the best one.
“Still waiting on a quote two weeks later.” Public review · kitchen manufacturer
“Three months and I still don’t have a price.” Public review · signage supplier
“Quoted one figure, invoiced another.” Public review · cupboard supplier
Every one of those is a job somebody else won. Not because the work was worse — because the answer was slower.
The shift
Your customer is on the couch at nine at night thinking about their kitchen. That is the moment you want to be in front of them — not three days later with a PDF.
Size, doors, drawers, finish, handles. It is your range, so everything they can pick is something you can actually make.
Calculated off your board rate, your edging, your hardware, your labour, your markup. Not a guess.
Name, contact, the full configuration and a cut list. Nothing to measure, nothing to re-key, nothing lost in translation.
What it actually does
Most 3D on the web is decoration. This is not: the model and the production document are calculated from the same numbers, so they cannot disagree.
Dimensions, layout, finish, hardware. Real geometry generated on the fly — there is no model file to download, which is why it opens instantly on a phone.
Every option carries your rate. Board, edging, hardware, labour, markup, VAT — itemised, and arrived at the same way you would arrive at it.
Every panel with its finished size and its edging. The document your saw operator works from, produced before the enquiry even reaches you.
Into your inbox or your CRM with the specification attached. Nothing to measure again, nothing to re-key, nothing lost between the two.

Every competitor demo shows a rotating box. None of them show a cut list — and the cut list is the part that proves the tool speaks your trade rather than merely looking good in a meeting.
Your range, your rates
Everything a configurator shows — products, options, finishes, hardware, rates — comes from one file that describes your business. Change the file, change the trade.
In the demo you can switch the whole thing from kitchens to gates to aluminium doors and windows to built-in wardrobes to shop fit-outs to garage doors to stone countertops to blinds and shutters to carports and decking, and watch the geometry, the labels, the material list and the prices change — same code, different file. Try that.
The guarantee
The price comes from the same numbers as the geometry, not a second calculation someone redid by hand under pressure — so it cannot quietly drift from what the job actually costs. GBlock sells buildings made of container modules; we broke a real project into 63 individually priced components so the quote always reconciles to the priced Bill of Quantities — exactly, not approximately.
This is the live GBlock engine, running right here — drag to orbit, walk the interior, or press Build It and watch the 63 components land in order.
Why this works
This isn’t just our own pitch — it’s the published, cited track record of interactive product configurators, across several vendors and their customers.
3×
the conversion rate of a static product page (0.8%) versus one with an interactive configurator (2.5%).
Forrester / Baymard Institute research, via Configurator.tech →
+40%
higher conversion reported by merchants after adding interactive 3D to a product page.
+30%
more turnover and 30% more inquiries for Molto Luce, a lighting manufacturer, after adding a configurator to its range.
508 leads
in 90 days for Caribbean Blinds, a pergola manufacturer — up from 6 a month before their configurator.
These are published results from other vendors and their customers, not a promise about yours — every business is different. What we can promise is narrower and provable: the price your customer sees on screen is the price on the invoice, every time.
Pricing
Fixed price, 50% deposit, the balance on delivery. You own the finished configurator outright once it is paid for.

Keeping it current: a care plan is R1,750 a month — hosting, uptime, and up to four price or catalogue changes, turned around in two working days. A configurator quoting last year’s rates costs more than the plan does.
The prices above are founding rates, limited to the first two clients in each trade, in exchange for a case study and a reference. After that they go to the standard rate shown.
Quote Engine
Every other package is right until your rates change, then it waits on us. The Quote Engine adds one page only you can reach — change a number on it and it is live for the next customer who opens the site, not the next time we redeploy it.
Board, edging, hardware, labour, markup, VAT — every line on the page above. Nothing goes live without your password, and every save is checked against the same rules the catalogue itself has to pass.
Every enquiry generates a quote document automatically — your logo, your reference number, your terms and exclusions — instead of you building one by hand from a screenshot.
A customer’s exact build gets its own short link, a QR code that opens it straight from a phone camera — useful stuck next to a sample on your showroom floor — and a one-tap 360° clip they can save and send over WhatsApp. Open it again next week and it is exactly as they left it, not a fresh start.
The enquiry lands wherever your sales process already lives, fully specified — nothing to re-key, nothing to measure again from a photo someone sent you.
How we work
Six things: your best-selling lines with dimension ranges; your finishes and materials; your hardware options; your pricing basis (board rate per m², edging per m, hardware, labour, markup, VAT); your logo; and the address quote requests should reach. The pricing basis takes the longest — start there.
Two to three weeks for a Configurator. The clock starts when the brief is complete, not when the deposit clears — so a slow brief moves the delivery date, not the price.
Two rounds of revisions included. We check the cut list against how you actually build a unit, because a list that assumes the wrong construction is worse than no list.
Your branding, your colours, your wording. Hosted, fast, and working on the phone in your customer’s hand.
Straight answers
No. The geometry is generated from dimensions, not from model files — that is why it loads instantly on a phone. If you have drawings, a SketchUp file or a photo of a hand sketch, send them. If you have nothing but a tape measure and a price list, that works too.
You do. Full ownership of the delivered configurator passes to you on final payment. We keep the underlying generic engine we reuse across clients — you are not buying a licence to your own tool.
No, and we would not claim otherwise. Your customer does not measure their kitchen and type it in — they configure a product within the templates you sell, and the setting around it is one we build to match your range. So a 600mm base unit stands in a properly proportioned fitted kitchen, a gate stands in a boundary wall on a driveway, a sliding door stands in a wall of a real room. That gives the sense of scale a white background cannot, without promising a survey nobody did.
They ask for it in the same enquiry. Every configurator ships with a custom requirements section: a non-standard size, a material you do not stock, a fitting to carry over, an awkward corner. Those lines arrive alongside the configured spec, counted and clearly marked to be quoted — never given an automatic price. The part the tool costed stays exact, and you quote the one-off yourself, which is the only honest way round. It also means the enquiry reaches you with the difficult part already written down instead of surfacing on site.
On the Quote Engine you edit them yourself through an admin page. On the other packages the care plan covers up to four changes a month, turned around in two working days. Either way the tool never quotes a rate you have stopped honouring.
That was the first design constraint. There are no model files to download and no app to install — the whole thing is under a third of the size of a typical web page, and it is built to run on a mid-range Android on mobile data.
The engine has run kitchens, gates, fencing, aluminium doors and windows, built-in wardrobes, shop fit-outs, garage doors, stone countertops, blinds and shutters, and a modular building system. Anything with a range, options and a price that depends on them fits the same shape — office furniture, paving, signage. If it does not fit, we will tell you before you pay anything.
Because they come from yours. We build the pricing from your rates and check the cut list against how you actually construct a unit, in the review round, before it goes live. The demo’s own arithmetic is covered by automated tests for exactly this reason.
