Estimating: from cost price to quote and cost review

Robin van Maasakker · 12 Nov 2026

The Calculatie (Estimating) add-on (€149 per month per company, excluding VAT) is the calculation environment before the quote. Per project you build an estimate with cost price, mark-ups and selling price, and turn it into a quote in the Offertes & Facturatie (Quotes & invoicing) add-on with one click. IFC estimating is included; there is no separate add-on for it. You find everything in the Calculatie (Estimating) menu, right after Quotes & invoices. With yearly billing you get 1 month discount. The Beamcore interface is in Dutch, so button and menu names are shown in Dutch with a translation.

What you do with it

  • Manual estimates: lines per building part (timber frame walls, roof, floor, cladding, insulation, membranes, sheet material or your own item) and per cost type (material, labour, equipment, transport, subcontracting, other), with quantity, unit, purchase price and waste percentage. Cost price, overheads, risk mark-up and selling price are calculated live.
  • IFC import with surface selection: import the IFC model, view it in 3D and select surfaces per element and zone. Beamcore calculates the square metres automatically and watches for double counting. You can always correct a calculated quantity by hand, with the reason recorded.
  • Build-up library: record per wall, roof or floor build-up which materials and labour are needed per square metre, with a price library and hourly rates. Assign a build-up to selected surfaces and the estimate lines follow automatically.
  • Quote from the estimate: after approval, Offerte genereren (Generate quote) creates a draft in the quotes module, with only the total amount, an amount per building part or all lines. Internal cost prices and margins never appear on the quote.
  • Cost review: put the estimated costs per cost type next to the actual hours from Time tracking and the issued material from Stock management, and see the actual margin per project.

How it works in outline

  1. In Calculatie (Estimating), click Nieuwe calculatie (New estimate): empty, from an existing project (project name, customer and description are copied) or from an IFC model.
  2. Fill in the project details and add lines, or let Beamcore take the quantities from the model.
  3. Choose the pricing method: a mark-up on the cost price or a target margin. On the right you always see the cost price, the selling price and the gross margin.
  4. Click Goedkeuren (Approve). The estimate is then fixed and you can generate the quote. You make a new version with Kopiëren (Copy).

Who is allowed

The administrator switches the add-on on via Abonnement wijzigen (Change subscription). Four permissions then apply: view, edit, approve and delete estimates. The admin role has all of them, a draughtsperson may view and edit, a planner may only view. An estimate with a quote can no longer be deleted, and a company only sees its own estimates.
