Airtable holds up beautifully until nine hundred Dunedin tenancies flip in the same fortnight
A custom internal tools build for a Dunedin property management firm, student accommodation provider, or multi-site operator runs NZ$45,000 to NZ$120,000 over 3 to 6 months. Retool, Airtable, and a stack of Google Sheets are genuinely fine at 40 units. They fail at 900, in February, when every viewing, bond lodgement, Healthy Homes statement, condition report, and maintenance request lands in the same three weeks and your team is answering all of it from a shared inbox.
You already know exactly when the wheels come off, because it happens on the same dates every year. Flats get signed months ahead, the old tenants move out at the end of the year, contractors need six weeks of clear access, and then in late February the entire cohort arrives at once. Your team is running viewings off a Google Calendar, keying bond details into Tenancy Services by hand, taking condition report photos on personal phones, and triaging maintenance requests that arrived by text, email, and a message on the office Facebook page.
Airtable will hold the data. What it will not do is enforce a sequence. It cannot stop a tenancy going live without a signed Healthy Homes compliance statement attached, cannot count down the working days you have left to lodge a bond, cannot tell you which twelve properties still lack a completed entry inspection with photographs, and cannot escalate a maintenance request that has been open six days when the tenant is a first-year who will not chase you. Every one of those gaps is currently patched by a person remembering, and in February that person is at capacity.
The fix: internal tools built for Dunedin, not rented
The case for building is that your February is a sequence, not a database. A custom tool encodes the order of operations: viewing booked, application screened, agreement issued with the compliance statement attached, bond received and lodged inside the statutory window, entry inspection completed with photographs, keys released. Each step blocks the next, each has a countdown, and the whole thing is visible on one board. That is a workflow engine, and workflow enforcement is precisely where no-code platforms stop and custom starts. The payoff is not elegance, it is that nobody has to remember anything on the twenty-second of February.

How long it takes, phase by phase
Exactly what you get
An operations console that owns the sequence, not just the data. Concretely: a flip board where every tenancy shows its blocking step and its countdown, compliance statement generation that cannot be skipped, mobile condition reports with photographs filed against the property, maintenance triage with contractor dispatch, and owner reporting that runs itself. You keep the source code and the database, and the tool is built to hand over to another team without drama. The parts that reach outside the office pair naturally with custom booking software for viewings, field service management software for the trades doing the work, and accounting software for rent ledgers and owner disbursements.
How to choose a developer in Dunedin
Sit a candidate team down in your office in the second week of February. If they cannot describe what they saw afterwards in terms of blocked steps and countdowns, they will build you a prettier spreadsheet. Ask specifically how they will handle a property manager standing in a cold flat on a phone with one bar of signal, because that is the real usage environment and it decides the architecture. Ask for a reference where the build survived a peak season, and ring it. Then ask for their recommendation on cutover timing; anyone willing to launch you into the February rush is optimising for their invoice, not your year.
- A single board showing every tenancy mid-flip with the exact step it is stuck on and how many days remain
- Bond lodgement prepared automatically from the tenancy record with the working-day countdown visible to the whole team
- Entry and exit condition reports captured in-app with timestamped photos attached to the property, which is what actually wins a Tribunal argument
- Viewings, applications, and key handover in one flow instead of three tools and a shared inbox
- Maintenance requests triaged by severity and escalated automatically when a tenant goes quiet
- You are replacing tools your team already knows. Expect a fortnight of slower work and some genuine resentment during changeover
- Do not attempt cutover in January or February. That pushes the real go-live into the mid-year lull and delays payback by months
- A workflow engine only helps if the workflow is agreed. If two branch managers do it differently, you are buying an argument you have been avoiding
- Ongoing hosting, support, and small changes are a permanent line item where Airtable was a subscription you could cancel
- !They propose a Retool dashboard without asking what blocks what; ask how they will stop a tenancy going live without a compliance statement
- !No mobile plan for condition reports; ask how a property manager photographs a wet wall in a Castle Street flat and files it correctly
- !They want to go live in February; ask them to justify that against a mid-year cutover
- !Nobody asks about your maintenance intake channels; ask how a text message from a tenant becomes a tracked job
- !Fixed price offered in the first call; ask what they assumed about your current process to arrive at it

Frequently asked questions
What does a custom internal tool cost for a Dunedin property management firm?
A tenancy flip workflow with mobile condition reports runs NZ$45,000 to NZ$70,000 over 3 to 4 months. A full operations console covering maintenance, owners, and reporting lands at NZ$85,000 to NZ$120,000 over 5 to 6 months. If your existing property software is mostly working, a workflow layer over it at NZ$28,000 to NZ$50,000 usually solves the February problem on its own.
Can the tool lodge bonds with Tenancy Services automatically?
It can prepare a complete, validated lodgement package and track the working-day countdown, which removes the two things that actually go wrong: incomplete details and missed deadlines. Full automated submission depends on what interface is available to you at the time, so treat this as prepared-and-tracked rather than fire-and-forget. Confirm the current lodgement options during discovery before anyone prices it.
When should we go live if our churn peaks in February?
Aim for a July or August launch so your team has two quiet months to get comfortable before the January sign-up rush. Going live inside the February window is the most common reason these projects are judged a failure, because staff revert to the old tools under pressure and never come back. Build backwards from that date: a 4 month project needs to start around March.
Will this replace our property management software or sit alongside it?
Most Dunedin firms keep their existing package for trust accounting and tenancy records, and build the workflow, inspection, and maintenance layer around it. Replacing the accounting core is expensive and rarely the actual pain. Ask your developer to justify any proposal that starts with a full replacement.
How do we handle photos and evidence for a Tenancy Tribunal dispute?
Capture condition reports in-app with timestamps and the property record attached, store the originals unaltered, and generate a report you can hand over as a single PDF. What loses disputes is not the absence of photographs, it is photographs nobody can prove were taken on the right day at the right address. Build the evidence chain in from the start rather than adding it after your first bad outcome.
Can we build this on Retool instead of from scratch?
Retool is a reasonable choice for internal admin screens over a database you already control, and it will be cheaper up front. It struggles once you need offline mobile capture, enforced sequencing with statutory countdowns, and tenant-facing screens. A common middle path is Retool for back-office views and a custom mobile app for inspections.
How long does it take to train a Dunedin team that lives in spreadsheets?
Plan two weeks of parallel running and one full day of hands-on training per role, then a fortnight where someone senior visibly refuses to accept the old spreadsheet. The technical migration is easy; the habit change is not. Budget the training time explicitly rather than assuming it happens in the gaps.
What ongoing costs should we expect after launch?
Hosting for a build of this size is modest, typically a few hundred dollars a month, and a support and enhancement agreement runs 15 to 20 percent of build cost annually. On a NZ$70,000 build, expect roughly NZ$11,000 to NZ$14,000 a year all in. Confirm whether that includes changes or only fixes, because the difference is significant.
Do we own the system if we part ways with the developer?
Yes, if you contract for it: full intellectual property assignment on payment, repository under your account, and documented access to hosting and the database. Ask for a written exit procedure before the build starts. A team confident in their work has no reason to resist any of this.

Who can build custom internal tools for a business in Dunedin?
Digital Heroes builds custom internal tools 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 internal tools 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.
