Custom Software Development for Sydney Businesses

Why a small Sydney business ends up running on spreadsheets and workarounds

The cause is size, not neglect. At 30 June 2026 the ABS counted 2,814,778 actively trading businesses in Australia, and New South Wales added 26,057 in 2025-26, the largest net increase of any state or territory (ABS). Splitting that total by employment size shows how few can afford their own development team:

Estimate: the ABS page publishes the 1-4, 5-19, 20-199 and 200+ counts but not the non-employing total, so we derived it as the total minus those four groups. The split is national, not NSW-only. The NSW Government separately says there are over 870,000 small businesses in the state, 97% of all businesses (NSW Government).

About 97 in every 100 Australian businesses have fewer than 20 employees. A self-check:

• If the same job details are typed into two or more places, the cause is missing integration, and automation is the fix.
• If only one person understands the master spreadsheet, the cause is a single point of failure, and a small internal tool with logins and history is the fix.
• If your process is your edge (how you quote, schedule or approve), packaged software will force you to change it. That is when custom software earns its cost.

What custom software costs a Sydney SME, and what drives the price

Devvista prices either as a fixed price from $500 to $100,000 depending on complexity, or hourly from $10 to $100 depending on the developer's level and the type of work, all in US dollars. The table multiplies assumed hours by an illustrative rate of $40 per hour, so you can see how a quote is built.

Estimate, not a quote: the hours are our planning assumptions, not measured results, and a fixed-price quote depends on scope. Odoo projects are scoped by module, with the Odoo licence charged separately (see Odoo pricing explained).

Three things move the number most:

1. Integrations. A system with a documented API is days of work. One without is weeks.
2. Data migration. Messy spreadsheets take cleaning before they can be imported.
3. Late decisions. A requirement changed in week six costs more than one agreed in week one.

Worked example (illustrative, AUD). A 15-person trades business retypes 30 accepted quotes a week into its accounting package at 12 minutes each. That is 6 hours a week, or 312 hours a year. If staff time costs AUD 50 an hour, the retyping costs about AUD 15,600 a year before counting errors. Compare any automation quote with that figure, converting currencies at the day's rate.

How a remote team works with you from first call to handover

Devvista works remotely. We have no Sydney office, ABN, phone number or address, and no clients there to point to, so we would rather say that now than have you find out later. Sydney is far from many remote teams, so the time difference is a fair objection. Here is how a project is run to make it a smaller problem:

1. Agree your working window first. At the start we agree with you the hours in which you can be reached and when meetings happen, and we write it down.
2. Discovery. A scoped conversation about the process, the people who use it and what must not break. You receive a written scope, a milestone plan and a quote.
3. Weekly demo. A working build you can click, shown live or as a recorded walkthrough you watch when it suits you.
4. Written weekly update. What was done, what is next and what we need from you, so a day spent in client meetings does not stall the work.
5. Staging before live. You test on a copy with your own data first.
6. Handover. Source code, designs, schemas and documentation are yours on completion and final payment, and a mutual NDA can be signed before any detailed discussion.

The trade-off is real: something urgent needs a call inside the agreed window. Read the offshore versus onshore comparison for the honest pros and cons.

Which Australian privacy rules affect a build, and what to ask any vendor

This section reports what the sources say. It is not legal advice, and you should take advice on how it applies to your business.

• The small business exemption. The OAIC says "a small business is one with an annual turnover of $3 million or less" and lists businesses the Privacy Act covers regardless of turnover, including health service providers and businesses trading in personal information (OAIC small business guidance). That page carries no date, so check it is current. The Act's current compilation, dated June 2026, still contains the small business section 6D (legislation.gov.au).
• The statutory tort. A tort for serious invasions of privacy commenced on 10 June 2025. The OAIC says it is "broader in application than the Privacy Act", reaching entities that may not be Australian Privacy Principle entities (OAIC). Its page does not mention small businesses by name, so we cannot say whether the exemption shelters you from it.
• Automated decisions in privacy policies. From 10 December 2026, APP entities that use a computer program to make, or substantially and directly support, a decision that could have a significant effect on a person's rights or interests, using their personal information, must say so in their privacy policy. The OAIC expects the duty to stay with the business using the tool, not the software vendor (OAIC APP 1 guidelines). The duty is on APP entities, so whether your business is one is a question for your adviser.

Ask any vendor, including us:

1. Where is the data hosted, and who can access it?
2. Which decisions in this system, such as pricing, screening or approvals, are made or shaped by software, so your privacy policy can describe them?
3. Who owns the code and the data, and how do you export both?
4. How are logins, roles, backups and deletion handled?

If you hold health or participant information, see our NDIS CRM guide for how these duties shape a system design.

Which processes to automate first, and which forced changes to plan for

Automate the work that is frequent, rule-based and currently done by retyping. A rough order:

1. Enquiry capture. A website or phone enquiry creates a record, assigns an owner and sends an acknowledgement. This is where a CRM pays back first (CRM development).
2. Quote to job to invoice. Data entered once flows forward. This is the usual first custom build.
3. Reminders and follow-ups for bookings, overdue invoices and renewals.
4. Reporting. A weekly figure arriving by email beats a spreadsheet someone rebuilds on Friday.
5. Anything that needs judgement or touches a decision about a person. Automate last, and keep a human in it.

If you are not sure where to start, start with number two. For AI-assisted steps such as sorting inboxes, see AI automation and our guide to what gets automated and what does not.

Two 2026 changes are pushing Sydney businesses to review their systems. MYOB switched off activation and confirmation for AccountRight Classic v19 and earlier on 28 February 2026, and company files become read-only after their next confirmation (MYOB). And from 1 July 2026, the Fair Work Ombudsman says employers pay super at the same time as wages, with contributions reaching the fund within 7 business days (Fair Work Ombudsman).

If you want accounting, inventory, projects and CRM in one system, Devvista is an official Odoo partner (owner's statement; see Odoo implementation). Payroll is scoped case by case. The wider Australian picture is on our Australia hub.

Is Devvista the right fit for your Sydney business?

A good fit if you run a business of roughly 5 to 150 people, one process in your business is costing hours every week, you can name an owner on your side who will watch the weekly demo, and you are comfortable with written updates and recorded walkthroughs.

Not a fit if you need people on site at your premises, want a fixed price before anyone has seen the process, or need an Australian entity, phone number or ABN to buy from. A firm with a Sydney office will serve you better then. We also do not give legal advice.

Comparing providers? Ask each for stated pricing, a sample weekly update and ownership terms in writing. More checks are in how to choose a software development company.

How to tell the software is working

Pick two numbers before the build starts and read them monthly:

• Hours per week on the process, from a two-week timesheet sample before and after. Our worked example above would target 6 hours falling to under 1.
• Time to first reply on new enquiries, measured in the CRM.
• Adoption. If staff still keep their own spreadsheet after eight weeks, the tool does not fit the process and needs changing.

Write the baseline down on day one, or nobody can say whether it paid back.
