About LimeLedger

About LimeLedger

LimeLedger was founded to transform how Australian construction and real estate businesses manage their finances, replacing manual processes and entry-level systems with AI-powered financial infrastructure built specifically for construction.

We saw too many businesses running their finances on systems built for small business, not construction: manually reconciling WIP in spreadsheets, chasing retentions in email, and losing weeks each month to a close that should take days. The solution was clear: Sage Intacct, implemented properly, with AI automation throughout, by people who genuinely understand construction accounting.

How we deliver: Australian-led, specialist-delivered

LimeLedger runs a two-hub delivery model. Our Sydney team leads every engagement - discovery, requirements, training and go-live - with Justus directly overseeing each project. Our Nairobi-based specialists handle technical configuration, integration development and QA.

Senior oversight on every decision. Specialist execution on every task. That's how every LimeLedger project runs.

Why LimeLedger

Construction finance transformation specialists
powered by AI and Sage Intacct.

Generic system integrators implement across dozens of industries on dozens of platforms. We don't. We transform construction finance, replacing fragmented, manual financial processes with Sage Intacct, AI automation and purpose-built construction accounting infrastructure. Built for Australian construction businesses that are serious about growth.

We understand construction accounting

Job costing, WIP schedules, revenue recognition, retentions, progress claims, TPAR and SOPA compliance, we know Australian construction accounting inside out and design systems that handle it properly from day one.

We design systems, not just install software

Anyone can install software. We design the financial processes, workflows and reporting structures that sit behind it, ensuring your system works in the real world of construction, not just in a demo environment.

Construction-focused, wherever you need us

Our team understands Australian construction regulations, GST, local industry dynamics, so your system is configured for compliance from day one, with support available when you need it.

A partner in your growth journey

We work alongside your team from initial design through to implementation and beyond. Our goal is simple: to give you a financial system you can rely on as your business grows, and a team that keeps it that way.

Direct senior involvement, every project

We take on a limited number of implementations per quarter. That means your project gets direct founder involvement from kick-off to go-live, not a junior consultant while the partner who sold you moves on to the next deal.

Enterprise-grade delivery at mid-market pricing

Our dedicated implementation team means faster delivery without the overhead of a large consultancy. You get the depth and quality of an enterprise implementation at a price point built for growing construction businesses, not large-consultancy billing rates.

AI-accelerated implementation

We use AI tools throughout configuration, data mapping and testing to deliver projects faster without compromising quality. That means a shorter implementation window, less disruption to your team, and earlier access to the ROI you're investing in.

The Process

What implementation actually looks like

A fixed timeline, agreed before we start. Four phases, no surprises.

1
Weeks 1 – 2
Discovery
We map your current system, chart of accounts, reporting needs and integration requirements. You get a fixed-fee proposal at the end.
2
Weeks 3 – 6
Design & Configuration
Job cost structure, dimensions, entities, approval workflows and contract billing, built to match your construction business from the start.
3
Weeks 7 – 10
Migration & Testing
Clean data migration from your existing system. Opening balances, historical job costs, subcontractor records, validated before go-live.
4
Weeks 11 – 14
Training & Go-live
Your team trained, your system live, your reporting working. We stay on for post-go-live support to make sure nothing falls through the cracks.
A straight answer

LimeLedger is a new practice built on deep experience. We do not have a library of published case studies yet. That is the honest position. What we do have is a founder who has delivered these implementations before, a structured methodology, and a fixed-fee model designed to reduce your risk. We are actively building our founding client cohort: a small group of construction businesses who want a Sage Intacct implementation done properly, at a price that reflects where we are right now. If that sounds like your business, let's talk.
