Covered pergola 5m x 4m over new hardwood deck, polycarbonate roof, two downlights, steps to lawn. Remove old pavers.
Run the build. We'll build the system behind it.
Decks, pergolas, outdoor rooms and extensions. WorkArc builds the system for variations, progress claims and margin, inside Fergus and Xero.

Four ways margin leaks.
They show up in almost every building business we talk to, usually after hours and usually at the owner's desk.
Variations eat the week
Every variation means re-pricing, re-scoping and paperwork. What should take ten minutes turns into two hours after dinner.
Progress claims pile up
Stage invoices, photos and supporting documents. Clients expect detailed claims and the paperwork keeps growing.
Subbie coordination
The electrician is delayed, the roofer is double-booked and the client wants an update. Coordination becomes a second job.
Job history is scattered
What was in the price, what was agreed on site, which variation was approved. The answers sit in emails, texts and notebooks.
The parts that pay back first.
We build these around your price book and your workflow, then keep improving them every month. The examples are illustrative.
- ArcAssist
Every job's history, one question away
Quotes, variations and client messages are kept together. Ask what was agreed and ArcAssist answers with the source attached.
On a job · illustrativeA client asks what the pergola price included. ArcAssist pulls the quote, the approved variation and the date it was signed off.
- ArcPulse
Cost against quote on every build
Stage by stage, from footings to handover. ArcPulse shows cost against quote on each build, so overruns show up while there is time to fix them.
On a job · illustrativeFraming on an outdoor room is running 14 hours over. ArcPulse flags it before the cladding goes on, while there is still room to recover it.
- ArcPortal
Clients see progress without ringing you
Each client gets a view of their build: stages, photos and what happens next. Fewer calls asking where the job is up to.
On a job · illustrativeFootings passed inspection on Thursday. The client sees the photos and the next stage date in their portal, and nobody had to write an email.
- ArcReport
See which builds make money
Decks, pergolas, outdoor rooms and extensions compared by margin. The weekly numbers arrive without anyone building a spreadsheet.
On a job · illustrativeThe report shows covered pergolas holding margin while small extensions slip, so pricing on extensions gets fixed before the next one is quoted.
From site notes to a priced quote.
Two illustrative examples: a quote built from a builder's notes, and the kind of question ArcAssist answers from your own job history.
What did we quote the Morrisons for the outdoor room?
$48,200 ex GST for a 6m x 4m enclosed outdoor room with bifold doors, plus variation V-02 for an extra power circuit at $1,180, approved on site.

Questions builders ask.
What builders usually want to know before a first call.
How does ArcAssist help with client questions?
Ask what was agreed on any job and ArcAssist answers from the quote, the approved variations and the messages, with the source shown.
Can it handle variations and staged progress claims?
Yes. Variations are priced from your own rates and added to the job, and progress claims are raised stage by stage with the supporting detail.
Will it work with Fergus or our job system?
WorkArc works inside Fergus and Xero, so builders keep the tools they already know and nothing gets entered twice. If you run another job system with an open API, we assess it case by case on the call.
What reporting do we get?
Margin by project type, cost against quote on every open job and a weekly summary of the numbers, delivered without anyone building them.
How do we get started?
Start with a 30-minute call. We look at how your builds run today, build the first part around how you already work, then keep improving it every month.
How it works.
The parts of the system mentioned on this page, and a few short reads for owners.
Works inside Fergus and Xero
We build inside Fergus and Xero, so your crews and office keep the tools they know. The quote, the job and the invoice stay in one flow, with nothing entered twice.
How we work inside themBuilt for each trade.

By city
