Asana will hold your Dunedin site programme and cannot hold retention money on trust or a payment schedule due in twenty working days
Custom project management software for a Dunedin construction, engineering, or professional services firm runs NZ$55,000 to NZ$160,000 over 4 to 8 months. Asana, Monday, Jira, and ClickUp are all competent task trackers, and none of them understand a payment claim, a payment schedule with a statutory response window, a variation that changes the contract sum, or retention money that must be held on trust. Those four things are where construction money is actually won and lost in New Zealand.
The programme is in one tool, the variations are in an email folder, the payment claims are in a spreadsheet, and the retentions are a number your accountant maintains separately. Your project manager knows where everything is, which is fine until two projects run at once and a subcontractor disputes a variation from four months ago. The evidence exists. It is just distributed across three systems and a phone.
The generic tools cannot fix this because their object model is a task. A payment claim is not a task; it is a dated instrument that triggers an obligation to respond within a fixed number of working days, and failing to respond properly has consequences that no amount of project tracking will soften. Retention money held on trust is not a project field either, it is a separate obligation with its own record-keeping requirements. Building around Asana means building the important half yourself anyway.
The problems nobody warns you about
- Payment claims and the working-day clock to respond are tracked in a spreadsheet outside the project tool
- Variations live in email, so the contract sum on the system and the contract sum in reality drift apart
- Retention money is maintained separately by finance, which makes the trust obligation hard to evidence quickly
- Subcontractor documents such as insurances and certifications expire without anyone noticing until an audit
The case for owning your project management
Build when your project data has legal consequences. A Dunedin build treats the payment claim as a first-class object with its own response deadline and status, keeps variations against the contract so the sum is always current, tracks retention money with the record-keeping the trust obligation requires, holds subcontractor compliance documents with expiry alerts, and links health and safety records to the site rather than to a filing cabinet. The programme and the tasks still matter, they are just no longer the hardest part of the system.
Budgeting a project management build in Dunedin
| Project scope | Typical cost | Timeline |
|---|---|---|
| Payment claims, variations, and retention tracking | NZ$55,000 to NZ$88,000 | 4 to 5 months |
| Full platform with subcontractor portal and site records | NZ$120,000 to NZ$160,000 | 6 to 8 months |
| Contract and claims layer over existing Asana or Jira | NZ$30,000 to NZ$56,000 | 2 to 4 months |
What your build should include
Dunedin project management: the full scope
Digital Heroes builds the full project management stack for Dunedin teams. Typical engagements cover time tracking, team collaboration software, workflow management, custom project management software, task management, Gantt charts and resource scheduling.
Exactly what you get
A system that treats contract obligations as seriously as the programme. Concretely: payment claims and schedules with working-day deadline counting, a variation register that keeps the contract sum current, retention tracking with a proper evidence trail, a subcontractor compliance register with expiry alerts, site diary and health and safety records tied to the project, and progress claims reconciled against recorded work. You own the code and the data. It connects to accounting software so claims and retentions reach your ledger cleanly, field service management software when defect and remedial work starts, and business intelligence (BI) dashboards for portfolio margin across concurrent Dunedin projects.
How to choose a developer in Dunedin
Ask a candidate to explain, without notes, what happens if a payment schedule is not issued in time. If they cannot, they will build you a task tracker with construction words on it. Ask for a construction or engineering reference and ring the quantity surveyor rather than the director, because the quantity surveyor will tell you whether the claims module actually works. Ask how they will get subcontractors onto the portal, since adoption by small trade businesses is the hardest part of the rollout. And insist on a heavy testing budget for anything that counts days.
- !They describe a payment claim as a task type; ask them to explain the response obligation in their own words
- !Retentions are not mentioned; ask how the trust obligation is evidenced in their design
- !No subcontractor onboarding plan; ask how a two-person Dunedin trade business gets into the portal
- !They have only built for professional services; ask for a construction reference and ring it
- !Testing is budgeted lightly; ask how a deadline calculation error would be caught before it costs you

Frequently asked questions
What does custom project software cost for a Dunedin construction firm?
Payment claims, variations, and retention tracking runs NZ$55,000 to NZ$88,000 over 4 to 5 months. A full platform with a subcontractor portal and site records is NZ$120,000 to NZ$160,000 over 6 to 8 months. A contract and claims layer over the Asana or Jira you already use costs NZ$30,000 to NZ$56,000.
Can the system track payment claim response deadlines automatically?
Yes, and it should count in working days with public holidays and the Otago anniversary date built into the calendar. Alerts escalate before the deadline rather than reporting after it. Have your legal adviser confirm the exact calculation rules for your contract forms before this is coded, because the details vary.
How does it handle retention money held on trust?
Retentions are tracked as a separate obligation with their own ledger and evidence trail, showing what is held, for whom, and on what project. That makes the trust position something you can produce on request rather than reconstruct. Involve your accountant in the design so the treatment matches how it is recorded in your books.
Will our subcontractors actually use a portal?
Only if it takes them under five minutes and works on a phone in a ute. Keep the portal to submitting claims, uploading insurance certificates, and acknowledging variations, and resist adding anything else. Budget for someone to personally onboard your top twenty subcontractors, because that human effort determines whether the portal succeeds.
Should we replace Asana or keep it for tasks?
Many Dunedin firms keep the task tool their site teams already use and build the contract layer alongside it, integrated so progress and claims stay aligned. Replacing a tool people actually use in order to add contract features is a fight you do not need. Ask your developer to price both approaches.
How does this connect to our accounting system?
Approved claims, variations, and retention movements post into Xero or your ledger as structured transactions rather than being rekeyed. The project system stays the source of truth for contract position while accounting holds the financial position. Agree the posting rules with your accountant during design.
How long does it take to roll out across live projects?
Four to eight months to build, then bring projects on as they start rather than migrating live ones mid-stream. Moving a project that is halfway through its claim cycle creates exactly the ambiguity the system exists to prevent. Run the old process alongside for one full claim cycle on the first project.
What happens when construction legislation changes?
You fund the change, which is the honest cost of owning custom software in a regulated area. Keep a maintenance agreement that explicitly covers legislative updates so it is budgeted rather than negotiated under time pressure. Ask how your developer stays aware of changes, and do not rely solely on them for that.
Can we hire developers in Dunedin to support this long term?
Yes for general maintenance, and the city's low turnover helps with a system that carries this much institutional knowledge. What matters more is documentation of the deadline and retention logic, since that is where a new developer could do real damage. Insist the rules are documented in plain language alongside the code.

Who can build custom project management software for a business in Dunedin?
Digital Heroes builds custom project management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Dunedin gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other project management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
