Avontus alternatives

Avontus sells two products that people look to replace: Avontus Designer, Windows software for designing system scaffolds in 3D, and Avontus Quantify, Windows software for rental, inventory and logistics. This page lists the alternatives to each, one row per tool, with what its vendor publishes. Written by the maker of ScaFix, one of the tools compared. ScaFix stands last among the design tools, not first. Every other row comes from that vendor's own pages, read on 25 October 2026; corrections to support@scafix.app.

What can replace Avontus Designer or Avontus Quantify?

For design, the alternatives to Avontus Designer are Scaffcalc (browser, FEM), ScaffPlan (SketchUp, Tekla), SMART Estimator (Windows, TG20:21), NTI SCAFFPLANNER (Revit), LayPLAN CAD, iScaf, scaffmax, PERI QuickSolve and ScaFix (browser and iPhone). For rental and stock instead of Quantify, look at iRent, ScaffPlan Assets or SMART Manager; ScaFix does not manage rentals.

Replacing Avontus Designer

Avontus Designer's strengths are breadth and CAD exchange: catalogues from over 40 manufacturers on the Professional licence, built-in ringlock, cuplock and Kwikstage parts, plans imported as IFC, PDF or AutoCAD files and models exported as .dwg and PDF. It is billed every 28 days plus a one-time start-up fee, and it runs on Windows only.

The closest like-for-like replacements are other desktop and CAD tools. iScaf is a Windows 11 program with its own AutoCAD drawing engine and regional system modules. SMART Estimator adds quotations, IFC exchange and the UK's TG20:21 checks for tube and fitting. ScaffPlan and NTI SCAFFPLANNER put the scaffold inside Tekla, SketchUp or Revit. LayPLAN CAD does the same in AutoCAD, for Layher only.

If the reason to leave is Windows itself, the browser tools are the change: Scaffcalc for multi-brand design with FEM and quotes, PERI QuickSolve for PERI products, and ScaFix for facade scaffolds of 108 systems in the browser and on the iPhone.

Replacing Avontus Quantify (rental and stock)

Avontus Quantify Small Business costs USD 349 every 28 days plus a USD 1,495 start-up fee and covers inventory, logistics and rental management for single-branch companies; Enterprise and Industrial are priced by sales. It runs on Windows.

Three alternatives on the vendors' own pages: Scaffolding Software's iRent ERP Inventory («a comprehensive inventory control system») with iRent ERP Invoicing; ScaffPlan Assets, which tracks gear across yards, branches and sites, including deliveries, returns and transfers; and SMART Manager, which tracks extra hire and works in the browser. None of them publishes a price on the pages read.

ScaFix is not one of them. It keeps one parts stock per account and shows what is short for a job, but it has no hire periods, dispatch, returns, invoicing, API or ERP sync.

How this list was made

A tool is listed only if its vendor publishes a product page that could be read on 25 October 2026. Facts are copied from those pages; a cell that says «not stated» means the page does not say. No tool is rated or ranked: the rows are alphabetical, with ScaFix last because ScaFix publishes this page.

Pick another tool if…

you need CAD drawings and BIM exchange like Designer's: iScaf, SMART Estimator, ScaffPlan, NTI SCAFFPLANNER or LayPLAN CAD;
structural checks matter: Scaffcalc (FEM), ScaffPlan (Tekla), NTI (strength calculations), SMART (TG20:21, tube and fitting);
you are replacing Quantify: iRent, ScaffPlan Assets or SMART Manager;
you plan one brand only: LayPLAN (Layher), PERI QuickSolve or scaffmax (PERI).

Pick ScaFix if…

you want to leave Windows-only software and plan in a browser on a Mac or PC, or in an iPhone app;
you plan facade scaffolds for houses and blocks, and a parts list in minutes is the goal;
a start-up fee does not suit you: ScaFix has weekly and yearly plans with no start-up fee;
your yard stocks Nordic or European frame systems such as Jamax, HAKI Ram, Plettac SL or Layher Blitz.

What ScaFix does not do

No structural analysis: no FEM, no load or stability calculation. ScaFix is a planning aid, not structural approval.
No CAD drawings (.dwg), no IFC or BIM exports and no import of AutoCAD files.
No rental management like Quantify: no hire, dispatch, returns, invoicing, API or ERP sync.
No free plan.

What ScaFix costs

From ScaFix's own price list: the first week of Pro costs €0.98, then €9.98 a week until you cancel (cancel in the first week and access ends at once). The yearly plans cost €39.90 (Basic Light), €79.90 (Basic) and €149.90 (Pro) a year. Rounded corners, silos, hanging scaffolds, hoists and mobile and stair towers are Pro only.

Questions and answers

Is there an Avontus Designer alternative for Mac?

Avontus lists Designer as Windows only. Browser tools run on a Mac: Scaffcalc, PERI QuickSolve (PERI products) and ScaFix, which also has a native iPhone app (read on 25 October 2026).

Which Avontus alternative has no start-up fee?

ScaFix's weekly and yearly plans have none. ScaffPlan sells annual per-user licences; paid monthly, the first month costs more (GBP 575 instead of GBP 225 for the SketchUp tier). PERI QuickSolve is free of charge for PERI products. The rest quote on request (read on 25 October 2026).

What replaces Avontus Quantify?

Rental and stock products: Scaffolding Software's iRent ERP Inventory and Invoicing, ScaffPlan Assets and SMART Manager. ScaFix plans the job and lists the parts but does not run rentals.

How much does Avontus Designer cost?

Avontus lists USD 199 (Kwikstage) or USD 299 (Professional) every 28 days, plus a USD 545 or 645 start-up fee; GBP 160/245 plus 440/525 and EUR 185/275 plus 500/595. An own-outright licence is priced by sales (read on 25 October 2026).

Is ScaFix an Avontus alternative?

For planning facade scaffolds with a 3D model and parts list on any device, yes. For CAD drawings, BIM exports and complex system scaffolds, Avontus Designer does more; the ScaFix vs Avontus page puts both side by side.
