Made-to-order manufacturing: the bottleneck is the quote, not the shop

Most outdoor living manufacturers are already running made-to-order. Every pergola, veranda, garden room, and carport is built after the order is signed, against a site, a preference, and a regional regulation. There is no warehouse of pre-built 4x5m louvred pergolas in anthracite waiting to ship.

What most of them are not running is instrumented made-to-order. The configurator, the pricing engine, the configurable BOM, and the shop-floor handoff are four separate jobs, often glued together by a salesperson with a spreadsheet on a Sunday evening. That is where the manual quoting errors compound, one wrong line item at a time.

We were spending most of our week translating quotes into parts lists. Now the configured spec is the parts list. The Monday backlog disappeared.

This piece covers where the friction lives, and what changes when the four blocks share one source of truth.

What MTO means in outdoor living#

Made-to-order is a production model where goods are built only after a confirmed order, unlike make-to-stock, which builds to a forecast and ships from a warehouse. There is a middle ground, assemble-to-order, where standard sub-assemblies sit on the shelf and the final structure is built per order.

Outdoor living is mostly assemble-to-order in disguise. Profiles, posts, louvre blades, and screen fabric are stocked or sourced on standing orders. The finished structure is assembled, painted, and dispatched after the buyer signs. The order triggers the cut list, the powder-coat batch, and the install slot.

That model has three advantages over make-to-stock. Inventory: no warehouse of finished goods to fund or write down. Cash flow: the buyer’s deposit lands before the build cost does, which is why small trades scale without bank debt. Fit: the product is built for the buyer’s actual site and preference, which lifts referral rate and holds margin against mass-produced imports.

The structural problem is speed. MTO only works if the quote-to-build loop is short enough that the buyer does not take the cheaper quote that landed on the kitchen table on Tuesday while yours arrived Friday. First to quote wins is the industry truism.

Where MTO breaks#

The bottleneck is rarely the shop floor. It is the handoff between two parallel translations of the same product.

Translation one. The salesperson takes the rough spec on a call or site visit and types a quote in Word or a CPQ tool. That quote is what the buyer signs.

Translation two. The production engineer takes the signed quote and rebuilds it as a real bill of materials by hand. That BOM is what the shop floor cuts.

When the two translations drift, the install crew arrives with the wrong post height or the wrong screen colour. The remake eats the margin, and the salesperson spends the next week on a complaint call instead of a new lead. Even with a careful operator the drift rate is hard to push below a few percent. The visible symptom is quote speed. The invisible symptom is rework rate. They are the same problem.

The named numbers sit in the Hrovat case study, where the modular-house team rebuilt their quote-to-build loop on a single instrumented MTO stack: €133M in quotes, with 10,835 hours saved on work that used to be done by hand. Those hours went to the second installation crew and the new dealer market, not overtime.

The four blocks of instrumented MTO#

The fix is not a faster CPQ. It is one source of truth threaded through four blocks that already exist in the business, usually run by four different tools.

Block one. The configurator. The buyer designs the product in 3D on the public website: size, posts, roof type, finish, screens, accessories, updating in real time. The output is a structured specification, not free text. Every choice is a parameter the BOM can resolve against.

Block two. The pricing engine. A real number in the buyer’s currency, computed against real cost rules, margin bands, and regional installation modifiers. Not a “starting from” placeholder. It lands on the PDF before the buyer leaves the site.

Block three. The configurable BOM. A parameterised parts list. The configurator’s output resolves to the exact posts, beams, louvre count, motor, and fasteners for the chosen build. No production engineer rebuilds the spec by hand.

Block four. The shop-floor handoff. The BOM lands in the ERP, the cut list lands at the saw, the powder-coat batch is scheduled, the install slot is booked. If the spec changes between quote and build, the change ripples through every block without anyone retyping it.

The technology stopped being the hard part years ago. WebGL is mature, CPQ has existed for two decades, ERPs handle parametric BOMs as standard. What is hard is wiring the four blocks to share one parameter set.

What changes when MTO is instrumented#

The shop floor was already good. The change is in three places that used to be invisible.

Monday morning. Before: a stack of contact-form lines and weekend voicemails, three hours of triage. After: configured PDFs with the build, price, and BOM attached. The team picks the inquiries with the longest time in the configurator first, because intent is visible in the data.

The drift rate. Before, three to five percent of jobs needed a remake. After, the configured spec is the parts list, so drift falls to whatever the configurator’s rule library still misses. With a mature configurator, that number is closer to zero than to one.

The founder’s calendar. Before, the founder is in the quoting loop on every job above a certain size. After, the founder is in the production-strategy loop and the dealer-network loop. What used to take a Saturday now takes a click.

The 1-day claim for premade visual sales systems is real, and it buys the buyer-facing layer: configurator, pricing engine, and PDF live on a public URL. BOM wiring and the shop-floor handoff take the rest of the quarter, because the ERP has to be taught the new vocabulary.

When MTO is not the answer#

MTO is a fit for products that have to be specified per buyer. It is the wrong model for products that ship off the shelf.

The unit economics for instrumented MTO hold above 5,000 euros AOV, and they get more attractive every step up the ticket. Outdoor living typically runs between 8,000 and 35,000 euros per build, which is why the category is a textbook fit. Modular houses, kitchens, container rooms, and saunas sit higher and are even more attractive on paper, with the caveat that the configurator has more rules to encode before launch.

The eight checks before you instrument#

If the decision is to move from manual MTO to instrumented MTO, the demo is where the vendors sort themselves out.

1. 01

   One parameter set across the four blocks

   Ask the vendor to show the same parameter, say roof type, flowing from the configurator UI, through the pricing engine, into the configurable BOM, into the ERP export. If any block uses a different vocabulary, the second translation is back. Non-negotiable.

2. 02

   A real configurable BOM, not a flat parts list

   The BOM has to resolve from the configurator's parameters, not be retyped against a quote. Ask for a live demo with a buyer changing the spec mid-flow and the BOM updating without a person in the loop. Non-negotiable.

3. 03

   Premade for your category

   A vendor with a pergola template, a veranda template, a garden-room template, a carport template has spent the years learning the rules already. A generic 3D vendor with no category template is asking you to fund the learning curve. The premade route launches in 1 to 10 days; the generic route quotes 3 to 6 months for the same outcome. Non-negotiable.

4. 04

   A real pricing engine, not a 'starting from'

   Ask the vendor to price a specific configured build on the spot. If they say the pricing module will be configured later, the answer is no. The pricing engine is the thing that turns the configurator into a quote desk.

5. 05

   A designed PDF the buyer will keep

   The PDF should look like your brochure, list the spec line by line, show the price, and read as a serious document. A screenshot and a number is not a quote.

6. 06

   ERP and CRM events on the wire

   The configurator should fire events to the ERP, the CRM, Meta, Google Ads, and GA4 the moment a buyer designs, prices, and submits. Without those events, the marketing layer cannot tell ad spend from organic, and the operations layer cannot tell a serious inquiry from a tire-kicker.

7. 07

   Mobile performance on 4G

   Open the demo on a phone, on real data, not on the showroom Wi-Fi. More than half of outdoor living traffic is mobile. If the 3D model takes eight seconds to load, the buyer is back in their feed before the build resolves.

8. 08

   Three reference trades in your category

   Ask for three named outdoor living manufacturers running the same vendor in production. Call two. The line you want to hear is 'the quote-to-BOM handoff is gone.' If you only hear 'the demo looks good', the reference is vanity.

The first three are gates. If the vendor cannot share one parameter set across the four blocks, cannot demo a configurable BOM that resolves live, and cannot show a category-specific premade template, the next five do not matter. The last five are how good vendors separate from average ones.

The thing MTO is really about#

Made-to-order is, on paper, a production model. In practice, it is a positioning bet. The trades that run it well are betting the buyer will wait two weeks for a structure built to fit their site, instead of taking the cheaper off-the-shelf product down the road. That bet only pays off if the wait is two weeks, not eight, and the quote arrives in minutes, not days.

The configurator, the pricing engine, the configurable BOM, and the shop-floor handoff are what make that bet hold. The gap is not the shop floor. It is what happens between the buyer’s first click and the cut list.
