Construction and fabrication estimating
Component lists, labour, materials and waste logic structured so estimators produce consistent quotations.
We bring deep practical experience and a proven understanding of the challenges and solutions in this area.
Quotes that are fast, consistent and commercially controlled
XLS Experts creates structured quoting and estimating systems that improve accuracy, speed and consistency — from advanced Excel estimators through to cloud quoting platforms with approvals and CRM links.
Most businesses that come to us have already tried off-the-shelf quoting software and found it almost fits — but forces their pricing to work the software's way instead of theirs. We build custom quoting and estimating tools around how your business actually prices work: in Excel when that's the practical answer, or as a connected web-based quoting application when you need multiple users, approval steps and live CRM or Xero links. Whether you call it a quoting tool, an estimating system, a job-costing spreadsheet or a pricing calculator, the goal is the same — fast, consistent, commercially controlled quotes that reflect your real costs and protect your margin.
Common quoting problems we solve
When quotes take too long, pricing differs between staff, or margins are applied inconsistently, the business loses both time and commercial control.
Solutions may range from an advanced Excel estimator to a fully cloud-based quoting platform. We match the design to quote volume, complexity and how proposals are issued.
When off-the-shelf quoting software isn't enough
Products like Xero, Simpro, Buildxact and NextMinute cover standard quoting well. If one of them fits how you price, you should use it — and we'll tell you so for free.
The businesses we help are usually the ones where standard software doesn't quite fit, because their pricing carries logic no generic tool captures: cutting-stock optimisation, complex bill-of-materials, tiered labour rates, project-specific margin rules, or estimates that pull from several sources at once. Forcing that into a rigid template means either overquoting and losing the job, or underquoting and losing the margin.
A custom quoting system is worth it when your estimating is specific enough that nothing off the shelf quite fits, and where a faster, more accurate quote directly protects your win rate. We build the tool around your process rather than the other way round — and it still feeds the systems you already run, including Xero and MYOB.

The ten pillars of an effective costing and quoting system
Start with the process, not the technology. A costing system is usually an accumulation of operational knowledge, pricing rules and workarounds built up over years. We start by understanding what you already have, keep what works, and fix the weaknesses that hold back accuracy, control or growth. These are the ten things we make a high-performing costing and quoting system do.
- 1
Capture and encode every line item accurately
Take-offs, products, services, treatments, options, quantities and units encoded consistently, so the final cost or price is reliable and you can always explain how it was reached.
- 2
Support the way your business prices
Cost-up-to-margin, pre-configured selling prices or a hybrid model — with multiple users able to work at once from shared project and price-list data.
- 3
Apply rates, mark-ups and commercial rules consistently
Rate bases, mark-ups, minimum charges and allowances maintained in one controlled place, while still letting you authorise and record exceptions.
- 4
Handle complexity, exceptions and manual overrides
Represent non-standard work and one-off adjustments openly, without burying them in formulas or corrupting the standard data other quotes rely on.
- 5
Accommodate scenarios, variations, exclusions and margin adjustments
Model alternatives, variations, exclusions and contingencies while keeping the link between the original quote and later commercial decisions intact.
- 6
Check, flag and approve unusual results
Catch missing information, anomalous quantities, mismatched units and thin margins before a quote is issued, with review and approval controls built in.
- 7
Present quotes the way each client expects
Separate the internal calculation from the external document, so you can issue item, component, package, project or combined quotation formats to suit the customer.
- 8
Connect quoting to the rest of your business — and to others
Exchange data with your internal systems and with customers, suppliers and subcontractors through files, databases, APIs and workflow hand-offs, including Xero and MYOB.
- 9
Turn quoting and project data into insight
Compare performance by job type, job size, estimator, salesperson, project manager, customer, category, margin, outcome and variations — so quoting becomes business intelligence, not just paperwork.
- 10
Use AI where it genuinely helps
Apply AI to organise information, reduce manual processing, surface patterns and support decisions, with review controls matched to the commercial risk.

Industries and trades we build quoting systems for
The right quoting system depends on how your trade prices work. We've built estimating and quoting tools for:
- Construction and building — take-off-driven estimates, subcontractor pricing, variations.
- Structural steel and fabrication — cutting-stock optimisation and material-waste control.
- Engineering and machining — process-based costing and quote-to-drawing workflows.
- Manufacturing — bill-of-material estimates that update with input costs.
- Electrical and mechanical services — rate cards, packages and labour-hour pricing.
- Joinery and cabinetry — material, hardware and labour build-ups per unit.
- Professional and field services — packaged pricing with optional extras and controlled margins.
Excel, a connected web app, or both
Low-volume, specialist estimating often works best as a custom Excel quoting tool: fast to build, low cost, works offline, and able to hold pricing logic that would be awkward to force into a SaaS product. It's frequently the right first step.
A browser-based application can complement Excel, replace selected parts of the process, or become the primary system — the right choice when several people quote at once, approvals matter, or quotes need to sync to a CRM, Xero or a customer portal.
The economics of custom development have changed. AI-assisted programming tools let us deliver more functionality in less time, making some solutions viable that were previously dismissed as too expensive to build. Many projects start as a structured Excel estimator, then we migrate the same pricing logic into a web application once volume or team size makes it worthwhile — so you're never rebuilding from scratch.

How we deliver quoting systems
Understand the current process
We map how work actually happens today — who uses the system, where data comes from, and what slows the team down.
Identify the right level of modernisation
Not every process needs a full rebuild. We recommend the simplest approach that solves the business problem reliably.
Build and test the solution
We deliver working software early, refine it with real users, and validate edge cases before go-live.
Support implementation and ongoing improvement
Training, documentation and a clear path for enhancements so the system keeps matching how you work.

View case studies on our homepageFrequently asked questions
Can you start with Excel and move to a cloud platform later?
Yes. Many quoting projects begin as a structured Excel estimator. When concurrent users, CRM sync or customer portals become important, we migrate the logic into a cloud application.
Can margins be locked down?
Yes. We can enforce minimum margins, role-based overrides and approval rules so commercial policy is applied consistently.
Can quotes sync to our CRM?
Where your CRM supports it, we can create or update opportunities, attach quote documents and keep status aligned.
Do you handle construction and manufacturing estimating?
Yes. We have delivered quoting tools for fabrication, construction-related work and manufacturing bill-of-material scenarios, as well as service pricing.
Can historical quotes inform new estimates?
When past quotes are stored in a structured way, we can surface comparable jobs and pricing patterns to support estimators.
How much does a custom quoting system cost?
Most projects are fixed-price once we've scoped them. A focused Excel estimator is a smaller piece of work than a multi-user web application with approvals and CRM sync. We quote after we understand the process, so you know the price before we start.
How long does it take to build?
Timeframes depend on whether we are building a focused Excel estimator or a multi-user web application. We deliver a working version early and refine it with your team rather than disappearing for months.
Do we have to replace our accounting or job-management software?
No. The quoting system sits alongside what you already use and feeds it — including Xero and MYOB. It replaces the estimating, not your whole stack.
We already have quoting software that doesn't quite fit — can you extend it instead of replacing it?
Often, yes. Where your existing tool exposes an API or export, we can build around it rather than starting over.
Can it handle unusual pricing logic — cutting stock, bill-of-materials, tiered rates?
Yes. That's usually why businesses come to us — the pricing logic is the part off-the-shelf tools can't do.
Is our pricing data kept confidential?
Yes. Your rates, margins and customer data stay yours, treated as confidential throughout.
