Most accounting firms did not design their tech stack. They grew one. A ledger came first, then a task app, then an e-signature subscription, a file-sharing service, a proposal tool and a shared inbox nobody fully trusts. Each purchase made sense on the day. Together, they mean your team re-keys the same client details into five places and nobody can say where a job really stands.
This guide is for Australian accounting, bookkeeping and advisory practices. It covers the layers of a practice tech stack, how to judge each tool, what a typical stack costs in Australian dollars, the security basics the ATO expects you to cover, and how to change your stack without disrupting a busy season.
What is an accounting firm tech stack?
Your tech stack is every piece of software your practice depends on to win, serve and bill clients, plus the connections between them. The connections matter as much as the tools. A strong stack moves a client's details from first enquiry to engagement letter, to the job, to the invoice and the ledger without anyone typing them twice.
The eight layers of a practice stack
Most firms need something in each of these layers. Some tools cover more than one.
1. Client accounting software. Xero, MYOB or QuickBooks, depending on the client. This is the system of record for your clients' books. Your practice tools should connect to it, not compete with it.
2. Tax and compliance. Your tax return software, SMSF tools such as Class or BGL, ASIC services and the ATO's online services for agents. This layer is set by your work mix and is rarely the place to economise.
3. Practice management. The client record, tasks, workflows, deadlines, time and billing. This is the layer that decides how your team spends its week.
4. Documents and signatures. Where client files live, who can see them, and how engagement letters and approvals get signed.
5. Email and client communication. The shared inbox, templates and campaigns. If client email lives in individual mailboxes, so does client history.
6. Proposals, engagement and payments. Quoting, getting the engagement letter signed, and collecting fees. Ignition is the best known Australian option.
7. Security and identity. Multi-factor authentication, password management, access control and backups.
8. Automation and AI. Rules that create the next task, draft the first reply or summarise a long email thread, so the team reviews instead of typing.
How to judge each tool
Feature lists look the same on every vendor site. These six questions separate tools that fit an Australian practice from tools that merely demo well.
Does it connect to the ledgers your clients use? Ask for the integrations that are live today, not on a roadmap. Check Xero, MYOB and QuickBooks by name, and what data actually syncs.
Where is client data hosted? Client tax data should sit in Australian data centres. Ask the vendor where the data lives, how it is backed up and which security certifications they hold.
What is the real price per person per month? Compare in Australian dollars, ex GST, at the same number of users. Watch for per-client fees, add-ons for features you assumed were included, and US-dollar pricing that moves with the exchange rate.
Is there one record per client? If the CRM, the task app and the file store each hold their own version of a client, you have not solved the problem. You have moved it.
How easy is it to leave? Ask how you export your data. A vendor that makes leaving hard is telling you something.
Will it still fit at twice your size? Check user limits and whether the price jumps in steps.
Consolidate or assemble best-of-breed?
There are two honest approaches, and each suits a different firm.
Best-of-breed means choosing the strongest tool for each layer and joining them with integrations. It suits firms with a specialist need, such as heavy SMSF work, and someone in the team who enjoys managing software. The cost is coordination: more logins, more invoices, more places for a client record to drift out of date.
Consolidated means one platform covers practice management, documents, signatures, email and billing, and you add specialist tools only where you must. It suits firms that want fewer subscriptions, one client record and a faster start for new staff. The cost is that no single platform is the deepest option in every area.
Most firms land in the middle: one core practice platform, the ledger and tax tools their clients require, and a small number of specialist add-ons.
What does a practice stack cost?
Here is a worked example for a 10-person firm, using published list prices in A$ per month ex GST at the lowest published rate, checked on 19 October 2026. Check each provider's own site before you decide, because prices change.
| Stack | What it covers | Per month |
|---|---|---|
| Xero Practice Manager plus Ignition | Practice management, plus proposals and payments | A$398 |
| Portal 360 Professional (10 users) plus Proposal Studio | Practice management, e-signatures, client files, email and proposals | A$639 |
| Karbon plus Ignition | Practice management, plus proposals and payments | A$1,104 |
Karbon prices in US dollars, so its figure is converted at A$1 = US$0.69.
Read that table carefully. Xero Practice Manager and Ignition is the cheapest line here, and Xero Practice Manager is free for Xero Silver, Gold and Platinum partners. If you only need job tracking, proposals and payments, that stack is good value. Where the picture changes is everything it leaves out. You will usually still pay separately for e-signatures, a client portal, a shared inbox and file storage. Count those subscriptions, then compare.
Security: the part you cannot trade away
Your clients hand you tax file numbers, bank details and identity documents. The ATO's current advice to tax professionals is plain: turn on multi-factor authentication, keep devices and software patched, run up-to-date anti-virus software, and confirm suspicious messages through contact details you already trust.
When you review your stack, check each tool against this short list:
- Multi-factor authentication is available for every user, and you can require it.
- Client data is hosted in Australia, with encryption at rest and in transit.
- You can remove a leaver's access in one place, the same day.
- The vendor can tell you who they are certified by, for example ISO 27001.
- You know who to call if something goes wrong. The ATO recommends tax professionals report data breaches to it so protective measures can be placed on client accounts, and your obligations under the Privacy Act, including the Notifiable Data Breaches scheme, may also apply.
Fewer tools also means fewer places to protect, which is a real security benefit of consolidating.
Where AI belongs in the stack
AI earns its place where work is repetitive and reviewable: drafting a first reply to a client email, summarising a long thread, filling in task details, or creating the right tasks from a plain-English instruction. Keep a person in the loop for anything a client will rely on. Choose tools where AI works on the client record you already have, rather than a separate chatbot that needs everything pasted into it.
A 90-day plan for changing your stack
Changing tools in the middle of a busy period is how firms end up resenting new software. A calmer approach:
- Weeks 1 to 2: audit. List every tool, its monthly cost, who uses it and what client data it holds. Most firms find at least one subscription nobody uses.
- Weeks 3 to 4: decide. Pick the layers you will consolidate and the ones you will leave alone. Run a free trial with two or three people, using real clients.
- Weeks 5 to 8: move by workflow, not all at once. Start with new clients and one recurring job type. Import existing clients from a CSV file instead of retyping them.
- Weeks 9 to 12: retire. Once the new tool has run a full cycle of a job, cancel the old subscription and export what you need.
Avoid cutting over in the weeks before a lodgement deadline.
Where Portal 360 fits
Portal 360 is an AI-powered practice management platform built for Australian accountants, bookkeepers, fractional CFOs and advisory firms. It covers the practice management, documents, signature and communication layers in one place, with a single client record, and Proposal Studio adds proposals and engagement letters. It connects to Xero on every plan, with QuickBooks, MYOB, Google Workspace and Microsoft 365 integrations as well. Data is hosted in Australian Microsoft Azure data centres with ISO 27001 certified security controls.
It is not a ledger and it is not tax preparation software, so it sits alongside your accounting and tax tools rather than replacing them. ATO client communication is live now, and direct ATO lodgement from the platform is coming soon.
Plans are A$29, A$49 and A$99 per user per month ex GST, with a 7-day free trial on Starter, Professional and Advanced.
