Xero closes your month beautifully and still cannot value the half-finished tank on your Seaview floor
Custom accounting software for a Lower Hutt business runs NZ$50,000 to NZ$120,000 over 4 to 7 months, and almost nobody should build a general ledger. Xero was founded in Wellington and stays current with Inland Revenue requirements, GST at 15 percent and payday filing; MYOB and FreshBooks do the same job to varying degrees. What none of them do is work in progress. At any moment a Seaview workshop has hundreds of thousands of dollars of partly finished work on the floor, and the ledger has no idea it exists until an invoice is raised.
Month end looks clean. Revenue is what you invoiced, costs are what you were billed, and the profit figure is confident and misleading. Half a dozen jobs are 60 percent complete with material consumed and labour spent, none of which is recognised, so a heavy month of buying followed by a light month of invoicing makes a good business look like it is bleeding.
The reverse is worse. A month where several jobs invoice at once looks excellent, and the cost of the work sitting behind those invoices was recognised weeks earlier. You cannot tell whether you are making money on the work you are doing right now, which means pricing decisions are being made on lagging, distorted data. Xero is not doing anything wrong. It is a ledger, and work in progress is a costing problem that ledgers do not solve.
The case for owning your accounting
Build the costing layer and keep Xero as the ledger. A custom Lower Hutt build captures material at issue, labour at timesheet approval and subcontract at commitment, values work in progress continuously, and recognises revenue against progress on longer contracts. It handles progress claims, retentions and variations properly for contract work, and pushes only clean journals and invoices into Xero so your accountant and Inland Revenue see exactly what they expect. You get real-time margin by job and job type without taking on the compliance burden of a general ledger.

Delivery, week by week
Exactly what you get
The costing layer Xero was never going to give you. Concretely: work in progress valued continuously from material issued and labour approved; live job margin before completion; progress claims, retentions and variations handled properly; clean journals into Xero with a reconciliation trail your accountant can follow; margin reporting by job type and customer; and cash flow forecasting driven by the actual pipeline. You get the source code, the accounting design documented and sign-off from your accountant. This depends on operational capture, so it works only alongside ERP (Enterprise Resource Planning) software for jobs, inventory management software for material issue, and HR (Human Resources) software for approved timesheets. The output usually surfaces in business intelligence (BI) dashboards.
How to choose a developer in Lower Hutt
Insist your accountant is in the room for design. This is one of the few builds where a technically excellent system can be commercially wrong, because revenue recognition and work in progress valuation are accounting judgements rather than software features. A supplier who is comfortable being challenged by your accountant is the one you want. Ask how they will prove reconciliation between the job system and Xero at month end, and ask what happens when the two disagree. Confirm they have built costing systems before, not just reporting dashboards, and be sceptical of anyone who proposes replacing your ledger, because that is a compliance burden you gain nothing by owning.
- Work in progress valued continuously, so monthly profit reflects work done rather than invoicing timing
- Job margin visible while the job is live, which changes what you quote next month rather than next year
- Progress claims, retentions and variations tracked in the system instead of in a spreadsheet nobody backs up
- Clean journals into Xero, so your accountant sees a tidy ledger and your compliance position does not change
- Margin analysis by job type, customer and estimator that is built from captured data rather than reconstructed
- This adds a system rather than replacing one, so you are maintaining both a build and a Xero subscription
- Work in progress accounting requires discipline, and if material and labour are not captured promptly the numbers mislead
- Your accountant needs to be involved in the design, which costs their time and may surface disagreements
- Revenue recognition policy is a judgement call, and getting it wrong creates a genuine audit conversation
- !They offer to replace Xero. Ask how they intend to keep pace with Inland Revenue changes, then reconsider
- !No involvement of your accountant. Ask them to bring your accountant into the design sessions
- !Revenue recognition is not discussed. Ask what policy their design assumes and who signs it off
- !Work in progress is treated as a report. Ask when material and labour are captured and by whom
- !No reconciliation design. Ask how you prove the job system and Xero agree at month end

Frequently asked questions
What does custom accounting software cost for a Lower Hutt contractor or manufacturer?
NZ$50,000 to NZ$75,000 for job costing and work in progress sitting over your existing Xero ledger, in 4 to 5 months. Adding progress claims, retentions and revenue recognition takes it to NZ$80,000 to NZ$100,000. Building a general ledger is not included because you should not do it.
Should we replace Xero with a custom system?
Almost certainly not. Xero maintains compliance with Inland Revenue requirements, GST at 15 percent and payday filing, and it does so continuously as rules change. Building that yourself means owning tax compliance risk in exchange for no commercial advantage, which is a poor trade at any price.
How does work in progress accounting actually change our reported numbers?
It moves cost recognition to match the work rather than the invoice, so a month of heavy buying and light invoicing stops looking like a loss. Practically, material issued and labour approved accumulate against the job as an asset until the job invoices. Your accountant needs to agree the policy, because it affects your reported profit and your tax position.
Can this handle progress claims and retentions on contract work?
Yes, and it is one of the strongest reasons to build. The system tracks claimed, certified, paid and retained amounts against each contract, flags retention release dates, and keeps variations linked to the original contract value. Most Lower Hutt contractors currently run this in a spreadsheet that only one person understands.
How do we make sure our accountant is comfortable with the design?
Bring them into design sessions rather than showing them the result. Agree revenue recognition policy, work in progress valuation method and the journal structure into Xero before any code is written, and get it in writing. An accountant who has signed off the design will defend it later; one who was shown it afterwards will question it.
What does this need from our operations to work at all?
Material issued when it is issued, timesheets approved weekly, and subcontract committed when it is ordered. Without that discipline the work in progress figure is confidently wrong, which is worse than not having it. If your shop cannot yet capture material at the point of issue, fix that first with inventory software before building the costing layer.
Can it forecast cash flow better than a spreadsheet?
Yes, because it can drive the forecast from real data: the job pipeline, scheduled progress claims, supplier payment terms and known retention releases. A spreadsheet forecast is a set of assumptions typed monthly; this is a calculation that updates as jobs move. The accuracy still depends on your pipeline data being honest.
How do we prove the job system and Xero agree?
Build a reconciliation report that runs at month end and shows every journal pushed, every invoice raised and any difference, with a drill-down to the transaction. Make it an acceptance criterion. Systems without a reconciliation report generate month-end disputes that consume more time than the system saves.
Is there a smaller first step if we are not ready for this?
Yes. Start by capturing material at issue and getting timesheets approved weekly, using internal tools rather than a full costing build. That alone gives you most of the job cost accuracy, and it proves whether your operation has the discipline this depends on. Digital Heroes often recommends that step before committing to the full work in progress layer.

Who can build custom accounting software for a business in Lower Hutt?
Digital Heroes builds custom accounting 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 Lower Hutt 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 accounting 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.
How can I check Digital Heroes is legitimate before getting in touch?
