Turn complex manufacturing costs into faster, more reliable quotes
XLS Experts builds custom costing, estimating and quoting systems for manufacturers, engineering businesses and fabricators where pricing cannot be reduced to a simple price list. Materials, labour, machine time, subcontract work, setup, waste and overheads can all affect the true cost of producing a job. We bring those variables together into a structured commercial system — from sophisticated Excel estimators through to database-backed web applications integrated with your existing business software.
Generic quoting software works when pricing is straightforward. XLS Experts builds custom costing and quoting systems when the price depends on the way the product is actually manufactured.
We are not primarily selling a generic quoting package. We model the commercial logic of the business — raw material consumption, components, bills of materials, labour, machine time, setup, production processes, subcontracting, waste, yield, overhead recovery, supplier prices, customer-specific pricing, markup, gross margin and quote revisions — so estimators can price a job the way the factory actually makes it.
This is particularly relevant for manufacturers, engineering businesses, steel and metal fabricators, boat builders, joinery and specialist building-product manufacturers, electrical assembly and control-panel businesses, and other make-to-order or configured-product companies where every quote or job is slightly different.
Many manufacturing and engineering businesses develop their estimating process organically. A spreadsheet begins with material prices and labour hours. Over time it acquires additional worksheets, lookup tables, special customer rules, manually maintained supplier prices, waste allowances, overhead calculations and exceptions that only an experienced estimator fully understands.
Eventually the problem is no longer simply producing a quote. The business needs to know: what will this job genuinely cost us? Have current material prices been used? Has labour and machine time been allowed for correctly? Is waste properly accounted for? Are subcontract processes included? What margin will the job actually deliver? Can another estimator reproduce the same price? How does the quoted cost compare with what the job ultimately cost to manufacture?
We build systems around those questions.
These are the patterns we see when manufacturing estimating has grown faster than the system behind it.
The objective is not simply to automate a spreadsheet. It is to capture the commercial logic of the business in a system that can be understood, maintained and applied consistently.
A useful manufacturing costing system is not only a quoting tool. It supports three connected commercial stages.
Capture the real cost drivers:
Apply controlled commercial rules:
Compare the estimate with what actually happened:
The right system captures the manufacturer’s pricing logic rather than forcing the business into a predefined model. What follows is typical of the commercial building blocks we assemble — not a fixed product checklist.
Maintain structured pricing for steel, timber, sheet materials, components, consumables or purchased assemblies. Costs may be based on units, length, area, weight, volume, packs or other industry-specific measures.
Where products are assembled from multiple parts, costs can be calculated from structured components or bills of materials. The structure can range from a relatively simple product recipe through to assemblies and configurable product options where the commercial requirement justifies it. This is not a claim of full MRP capability.
Support controlled supplier-price imports rather than manually updating individual spreadsheets.
Apply controlled labour rates by task, trade, department, process or skill level. Systems can distinguish internal labour cost, charge-out rates and recovered production rate where the business needs that separation.
Cost manufacturing operations beyond labour alone — CNC time, cutting, welding, finishing, painting, machining, programming, production-line time and equipment usage.
Separate one-off setup or preparation costs from per-unit production costs. That distinction matters particularly when comparing small and large production runs, because setup can dominate the unit cost of a short run and almost disappear on a long one.
Model realistic material utilisation. This can range from percentage waste allowances through to more specialised cutting logic, nesting assumptions, usable lengths, sheet utilisation, yield calculations and material optimisation.
Include external processes such as powder coating, galvanising, heat treatment, specialist machining, finishing, transport and outsourced fabrication.
Recover overhead based on appropriate commercial drivers such as labour hours, machine hours, job value, production quantities, fixed job charges, department or other business-specific allocation rules.
Support negotiated discounts, customer price structures, contract rates, minimum margins, volume-based pricing and special commercial agreements — controlled centrally rather than maintained in individual copies of spreadsheets.
Markup and gross margin are not the same thing. Markup is the amount added to cost; gross margin is that amount expressed as a percentage of selling price. Systems can calculate expected margin and apply minimum-margin warnings, approval thresholds, user permissions and management overrides.
The costing engine can feed the quoting workflow directly. The estimator should not need to calculate the job in one system and manually recreate the commercial proposal in another.
This is where manufacturing costing connects to our broader custom quoting and estimating systems: the same commercial logic that produces the cost also produces the customer-facing quotation.
The estimate becomes much more valuable when actual results are compared with the assumptions. Quoted cost versus actual cost is where a costing system turns from a quoting aid into a management tool.
If a particular product, estimator, process or type of work is consistently underquoted, management should be able to identify that pattern and adjust future pricing. That feedback loop is also where manufacturing costing meets project costing tools and production dashboards.
An estimate that cannot be compared with actual manufacturing cost is difficult to improve. Retaining the original estimate as a baseline lets the business see whether pricing logic, rates or waste assumptions need to change.
Structured estimate and actual-cost data can provide profitability analysis beyond a single quote. This is a management decision-making capability, not just a quoting tool.
Once estimates and actuals are stored in a consistent structure, profitability can be reviewed by customer, product, product family, job, job type, estimator, salesperson, material type, production process, business unit or factory/location.
These examples are drawn from work we have actually done, together with neighbouring estimating experience in construction, electrical, engineering and specialist trades. The underlying commercial challenge is often the same: combine materials, labour, processing, waste, supplier costs and commercial margin into a repeatable pricing model.
Material profiles, dimensions, weights, cutting requirements, labour and process costs can be combined into a controlled estimate. Where material utilisation matters, cutting and waste calculations can form part of the commercial model rather than relying on a simple percentage allowance. Small errors in material recovery can materially affect job margin.
Highly configurable products cannot always be handled through a fixed price list. We have built a custom pricing solution for a boat-building business where materials, components, labour, options and commercial rules are combined dynamically so the estimator builds the required product while the system calculates expected cost and selling price.
We have developed production tracking systems, including work for Bremworth Carpets that tracked manufacturing activity and individual carpet mills. That work was operational rather than a costing implementation, but it is relevant because it shows the relationship between estimating, production, operational data and actual results. Production and manufacturing dashboards in Excel are often the reporting layer that sits on top of that operational data.
We also developed a production and assembly tracking solution for a gift-box manufacturing business. That work is useful evidence of how production stages, work-in-progress, assembly workflow and throughput can be captured — without overstating it as a full manufacturing ERP.
Many engineering contractors, electrical businesses, fabricators and specialist building-product suppliers sit somewhere between project contracting and manufacturing. Their pricing may combine purchased products, fabricated components, labour, installation, subcontract work and project-specific variables. These are strong candidates for custom estimating systems.
Not every project needs a web application. One of the XLS Experts differentiators is the ability to use Excel when Excel is genuinely the right platform, then move through Excel VBA development and database-backed or custom web applications when scale, workflow or multi-user requirements justify it.
We use the simplest architecture that solves the business problem properly.
Suitable where calculations are complex, user numbers are low, flexibility is important, and Excel is already central to the business process.
Suitable where workflow needs automation, users need controlled interfaces, quotations need automated output, or business rules need stronger enforcement.
Suitable where data must be centralised, multiple users need simultaneous access, price lists and estimates need structured history, or permissions matter.
Suitable where users work across locations, mobile or browser access is required, workflow spans departments, or integration becomes important.
Suitable where information needs to move between ERP, inventory, accounting, CRM, production and estimating.
Manufacturing pricing rarely operates in isolation. We are not positioning this work as a replacement for every function in an ERP or MRP system.
Where an existing ERP already handles inventory, purchasing, customers, sales orders, production records or accounting, those systems can stay in place. The custom application manages specialist estimating logic that the ERP cannot model effectively. Once approved, quote or job information may then be passed back into the existing business workflow.
That is the same practical approach we take with workflow automation: fill the gap rather than replace systems that already work.
An ERP may remain the master system for products, customers, inventory and purchasing, while XLS Experts builds the costing, quoting or workflow layer around it. Potential integrations include ERP systems, accounting systems, CRM, inventory, supplier databases, product databases, production systems, Microsoft 365 and existing Excel workbooks.
Fill the gap rather than replace systems that already work.
The work begins with experienced estimators, not with a software template.
The important test is not whether the software calculates something. It is whether it calculates the commercial answer your experienced people trust.
Work through how experienced estimators currently determine a price: materials, processes, labour, waste, overheads, subcontracting, margin and exceptions.
Separate repeatable commercial rules, data inputs, estimator judgement and exceptions. Identify information sources such as existing spreadsheets, supplier files, ERP, historical quotes, product databases and experienced staff.
Develop the working model and validate it against real historic and current jobs. The important test is not whether the software calculates something. It is whether it calculates the commercial answer your experienced people trust.
Once the costing engine is reliable, add where useful: quote generation, approvals, CRM, ERP handoff, dashboards, permissions and document automation.
Where actual production or financial data exists, compare expected and actual job performance. This creates the profitability feedback loop.
XLS Experts does not approach these projects as a vendor of a generic manufacturing package. Our experience comes from building custom commercial and operational systems around real business processes — including engineering and fabrication estimating, material optimisation, configurable product pricing and production-floor tracking.
We have built quoting and estimating solutions for engineering and steel fabrication businesses involving material dimensions, steel profiles, material weight, cutting requirements, material utilisation, waste reduction, labour, job pricing and protection against underquoting. We have built a custom pricing solution for a boat-building business. We previously built an operational manufacturing solution for Bremworth Carpets that tracked production-floor activity and individual carpet mills. We also developed a production and assembly tracking solution for a gift-box business.
A significant amount of our estimating, costing and pricing experience has also come from construction, electrical, engineering and specialist trades. That neighbouring experience is highly relevant to manufacturing costing because the commercial problem is often the same.
Some clients need a sophisticated Excel costing model. Others need a shared quoting application. Others may need product, supplier, production and commercial information connected across several systems. We build only as much system as the business problem requires.
Examples of similar systems we have delivered for New Zealand organisations.

View case studies on our homepageA manufacturing costing system calculates the expected cost of producing a product or job by bringing together materials, components, labour, machine time, setup, subcontract work, waste, overhead and other relevant cost drivers. It can also apply pricing and margin rules to produce a controlled selling price or quotation.
Yes. Excel can be an excellent platform for complex manufacturing calculations, particularly for specialist estimators and smaller teams. When requirements expand to multiple simultaneous users, centralised data, permissions or wider workflow, the same costing logic can be moved into a database-backed or web application.
Yes. Many projects begin with an existing workbook that already contains valuable commercial knowledge. Where the underlying logic is sound, we can restructure, automate and extend it instead of replacing it unnecessarily.
Bill-of-material costing calculates product cost from the individual components, materials or assemblies required to manufacture it. Depending on the business, the structure may range from a simple component list to configurable assemblies and product options.
Usually, yes. Structured Excel, CSV or other supplier files can often be imported through a controlled update process. Where suppliers or existing systems provide APIs, more direct integration may also be possible.
Yes. Waste can be handled through percentage allowances or more specialised rules based on material dimensions, cutting requirements, yield and actual utilisation.
Yes. Labour can be costed by task, trade, department or process, while machine time, setup time and production processes can be allocated using appropriate rates.
Yes. A system can calculate expected gross margin and apply warnings, approval rules or permissions when a quote falls below required commercial thresholds.
Yes, where suitable production and actual-cost data is available. The original estimate can be retained as a baseline and compared with actual material, labour, subcontract and other costs.
Potentially, yes. Where the ERP provides suitable APIs, database access or import/export functionality, the custom costing application can exchange information with it rather than duplicating data unnecessarily.
Our focus is custom costing, estimating, pricing, workflow and operational applications rather than supplying a generic MRP or ERP package. Where an existing ERP already manages inventory, purchasing or production effectively, we generally prefer to integrate with it and build the specialist commercial functionality around it.
Yes. The same costing engine can feed quotation generation, revision management, PDF output, margin approval and quote-to-job or quote-to-sales-order processes.
Yes. Engineering and fabrication businesses are particularly good candidates because pricing commonly combines materials, cutting or utilisation, labour, processing, subcontract work and margin rules.
No. A.I. can assist with activities such as reading supplier documents, extracting enquiry information, interpreting specifications and categorising data, but the costing engine itself should remain a controlled commercial model. See our A.I. workflow automation work for where those supporting activities fit.
If your current estimating process depends on a complex spreadsheet, manual supplier lookups, one experienced estimator or commercial rules that generic quoting software cannot reproduce, show us how it works. We can help turn that knowledge into a structured manufacturing costing and quoting system that is faster to use, easier to maintain and gives you much stronger control over margin and job profitability.
