The work is there. The pricing hours are not. How to tender more without hiring an estimator

The invitations are there. The hours to price them are not. Every tender you decline teaches a main contractor to stop inviting you, and every one you price at the kitchen table after ten hours on site gets less rigour than your work deserves.

Quick answer: This page is for subcontractors whose tender volume is capped by pricing hours, not by opportunity. Trueworks delivers per-tender pricing packs: takeoff, bill of materials, supplier quote comparison, rate build-ups with the basis stated, a cost floor and a target price kept separate, and a qualifications register drafted from the gaps in the documents. You review the pack, adjust it, and own the final number — we never submit on your behalf and never contact the main contractor. The frame is estimating capacity as a variable cost: pay per tender, run three packs in a busy month, spend nothing in a quiet one, and skip the six-figure estimator overhead until your win rate justifies it. Turnaround is scoped at intake against your close date, and your first packet is at no charge.

If this is your week

An invitation to tender arrived this morning and your first thought was where the hours would come from, not whether the job is any good.
Pricing happens at the kitchen table after site hours, and the standard drops with the light.
You can price one, maybe two tenders a month between running jobs. The invitations run at twice that.
You declined two last quarter, and that main contractor has been quieter since.
A full-time estimator is a six-figure overhead, and you are not ready to carry one through a quiet winter.
Your best pricing fortnights are the fortnights your jobs on site get less of you.
You have never once had time to properly compare two supplier quotes before a close.

What we actually do for you

You send the tender pack as issued — drawings, specification, schedule, conditions — plus any supplier pricing you already hold. We do the document-heavy middle of the job: the takeoff, the bill of materials, the supplier comparison normalised so the totals actually compare, the rate build-ups with their basis stated. Then we hand you the two numbers that matter kept deliberately apart: a cost floor, which is what the job costs you, and a target price, which is the cost floor plus a margin decision that belongs to you and nobody else. Alongside them sits a qualifications and exclusions register drafted from what the documents do not say — the lines that protect the price you submit.

You review the pack, move the numbers you disagree with, make the margin call, and submit under your own name. We never contact the main contractor and we never submit for you. What changes is arithmetic: if pricing a tender properly costs you three evenings, and a pack reduces that to one sitting of review and decisions, the same month holds three tenders instead of one — without a salary, a workstation, or a quiet-season overhead you cannot switch off.

How it works

Send the tender pack. Everything as issued, plus supplier quotes if you hold any, plus the close date. The close date decides the plan, so it comes first.
We build the pack. Takeoff, bill of materials, comparisons, build-ups, cost floor, target price, qualifications register. Queries reach you batched, usually once, early.
You price and submit. The pack lands with enough clear days for you to review it, make the margin call, and lodge — that buffer is agreed at intake, not hoped for.

What lands back on your desk

The takeoff and bill of materials in working spreadsheet form, measurement conventions stated
A supplier quote comparison normalised to the bill, where you hold supplier pricing
Rate build-ups with the basis of each rate stated, so you can shift any input you know better
A cost floor and a target price, kept separate, so the margin decision is visible and yours
A qualifications and exclusions register drafted from the gaps in the documents
Risk flags with suggested allowances as ranges for anything the documents leave open

Where this catches real problems

Supplier decisions move real margin. When we normalised three supplier quotes to one bill of materials on an M&E package, the sharpest headline total was not the cheapest supplier — the gap only showed once the comparison was restricted to lines every document had priced. That is exactly the check that never happens at the kitchen table at eleven at night.

The cost-floor discipline is the heart of the pack. On an electrical tender, separating the cost floor from the target price meant the subbie could see precisely how much margin was in the number — and could cut with a floor under his feet when the main contractor came back asking for movement, instead of guessing which rate still had fat in it.

Speed without checking is how tenders go wrong quietly. A pre-submission audit found the broken-reference error that nearly mispriced the deepest pipe run — a rate calculator pulling from the wrong row, invisible in the total, expensive underground. Packs get audited before they reach you, because a fast wrong number is worse than a slow right one.

FAQ — tendering more without hiring

Q1: Who owns the final number? You do, entirely. The pack gives you the cost floor, the build-ups, and a target price, but the margin decision and the submitted total are yours. We would not want it any other way — you carry the contract, so you set the price.

Q2: How does this compare with hiring an estimator? An estimator is a fixed cost you carry through quiet months; a pack is a variable cost that scales to zero. Per-tender pricing is on trueworks.co.nz — priced per job, so you can put a number on each tender you could not otherwise price and decide whether the invitation is worth it.

Q3: Will the main contractor know someone helped with the price? Not from us. Nothing in the pack identifies Trueworks, we never contact the main contractor, and the submission is yours in your format. Whether you mention the support is your decision; most subbies treat it like any other supplier relationship.

Q4: What is the turnaround on a pack? Scoped at intake against your close date. A quote or document review returns within 24 hours; a mid-size single-trade takeoff and bill typically runs days, not weeks. We agree the delivery date — with clear days left for your review — before we start, and if the window cannot be met we say so up front.

Q5: What about confidentiality? An NDA is available as standard. Your files are processed on NZ-hosted systems and deleted after 30 days unless you ask us to retain them. Your rates, your suppliers, and your margins are not benchmarked across clients or reused anywhere.
