Key takeaways
5- OneBookPlus is consultancy software for Australian solo consultants and small consulting firms: quotes clients accept online, deposits, invoices with a Pay Now link, discovery call bookings and a client CRM. From $0/mo (Free), $29/mo (Starter) or $69/mo (Growth, AUD).
- AU sole-trader consultants are taxed at individual marginal rates with business income on their personal return. ABN is free at abr.gov.au and required to avoid 47% no-ABN withholding. OneBookPlus checks your ABN against the Australian Business Register when you set up, and prints it on every quote and invoice.
Show 3 moreShow less
- GST registration is required once turnover reaches $75,000 in any 12-month rolling period. Below that, GST is optional. If you are not registered, say so once in your business details and new quote and invoice lines go out without GST.
- Accepting a quote in OneBookPlus records the date and time it was accepted. It does not capture a name or a signature, so if an engagement needs a signed contract, sign that in a separate tool, and talk to your lawyer about anything that must be signed or witnessed in a particular way (deeds, real-property transfers, certain financial-services agreements).
- Engagement and retainer revenue should be recognised as the work is delivered (per AASB 15 / IFRS 15 'Revenue from contracts with customers'). OneBookPlus shows the profit and loss on a cash or an accrual basis, so your accountant can reconcile both at tax time.
Everything for the engagement
Built for how consultants actually work
Quotes, deposits, invoices, bookings and a client CRM, built around Australian GST and ABNs rather than adapted from a US freelancer tool.
Quotes Clients Accept Online
Set out the scope, fees and terms, and attach your engagement letter or brief as a file. The client opens the link and taps Accept, and you hear about it straight away.
Deposits When They Accept
Ask for a deposit on the quote, as a percentage or a set amount. If you take card payments, the client pays it on the quote page straight after accepting, and the invoice you raise from the quote bills only the balance.
Invoices with Pay Now
GST invoices with your ABN and a Pay Now link for card payment. Turn an accepted quote into an invoice, raise one for each stage of a fixed fee, or duplicate last month's invoice to bill a retainer.
Discovery Call Bookings
A booking page for discovery calls, with your services and the hours you take calls. Prospects pick a time and answer your intake questions, so you walk into the call already briefed.
Client Record with Timeline
Every quote, invoice and booking for a client on one timeline, your notes on the next tab, and what they have been invoiced, paid and still owe at the top. When a prospect calls back six months later, it is all there.
Outstanding and Overdue
Your home screen shows what is owed and what is overdue, and warns you when one client is more than 40% of the month's billings. Reminders go out 3, 7 and 14 days after the due date unless you change the days or switch them off.

Website included
A website for your consulting business, included.
Every paid plan includes a full website, hosted by us, with nothing extra to buy and no separate builder: your site, its booking page and the tools behind them sit on one plan. The Free plan keeps the booking page and does not have the website.
The AI drafts every page from your own answers about your consulting work, not from your business name, and it does not invent claims. Every page is laid out for a phone as well as a desk. In the Website Studio you edit any section in place, add text, lists and buttons inside it, choose how many cards sit across, and change the look, which keeps your words, your photos and the spacing you set. The booking page is built in and the site's Book buttons go to it. Your first AI build is included with the plan. A later rebuild runs on AI Companion credits, and one that starts fresh replaces your pages, saving a restore point in History first.
Bookings around the clock
A prospect lands on your booking page at 10pm and books a discovery call for Thursday. Your intake questions capture their problem statement, budget range and timeline, so you walk into the call already briefed, no back-and-forth email tennis.
Prices up front
Strategy sprint from $4,500. Monthly advisory retainer $2,800. A customer sees the price before they book.
Your services and the area you cover
The AI writes your services and the area you cover from your answers, so when someone searches 'management consultant in [suburb]' there is a page that says what you do and where.
No card needed to start.

Three businesses, three looks
All three sites were drafted by the AI from the owner's answers, our own site included. It picks one of eight heading and body type pairings and how the cards sit (a fine line, a bold outline, a soft lift or no card), so a plumber's site, a driving school's and ours do not come out alike. Switch the view to see each one on a desktop, a tablet and a phone, click any screenshot to see it full size, or open the live site in a new tab. The plumber and the driving school are our demo businesses, not customers.

The screens a client file passes through.
These are real product screens: the quote, the invoice and the client record.
A quote your client accepts online
Scope and fees as lines with GST on each, the total on top and a valid-until date. The client accepts from the link, and if the quote asks for a deposit and you take card payments, they pay it on the same page.
An invoice with a Pay Now link
The amount due on top, GST on every line, the payments recorded against it and the reminder schedule underneath, so you can see what has been chased and what goes next.
The client record
What a client has been invoiced, what they have paid and what they still owe, how many of your quotes they accepted, and every quote and invoice on one timeline, with your notes on the next tab.
From discovery to paid
How OneBookPlus works for a consultancy
Four steps from discovery call to paid invoice, designed around the engagement lifecycle most consultants actually run.
1
Step 1Prospect books a discovery call
Put your booking link in LinkedIn and your email signature. Prospects pick a time from the hours you set and answer your intake questions before you talk.
2
Step 2Send a quote they can accept online
Set out the scope, fees and terms, attach your engagement letter, and ask for a deposit if you want one. The client accepts from the link and you hear about it straight away.
3
Step 3Invoice the work
Turn the accepted quote into an invoice, which bills only the balance when a deposit was paid. For a fixed fee in stages, raise an invoice for each stage; for a retainer, duplicate last month's. Every invoice carries GST and a Pay Now link.
4
Step 4Get paid, chase less
Clients pay by card from the invoice. Reminders go out after the due date, and your home screen shows what is owed and what is overdue.

Who it's for
Built for every consulting model
From solo specialist to small consultancy. OneBookPlus scales without the legacy-suite price tag.
Solo Strategy Consultant
One-on-one engagements with mid-market clients. A quote with a deposit, an invoice for each stage, and a monthly retainer billed from last month's invoice.
Technical / IT Consultant
Implementation work and advisory retainers. A quote per project, an invoice per stage, and monthly support fees billed by duplicating last month's invoice.
Management Consulting Boutique
Small team, several workstreams per client. A login for each consultant, every quote and invoice on the client's record, and what is owed on the home screen.
Specialist Advisor
Niche advisory in a regulated industry: fees set out on the quote before the work starts, invoices with your ABN, and each client's full history on one record.

Example walkthrough
Friday, an engagement scoped and invoiced
An illustrative walkthrough of a typical consulting day
You open the dashboard at 8am: what is owed, what is overdue, and the quotes still waiting on an answer.
First thing: a new prospect booked a discovery call yesterday through your booking link, and their answers to your intake questions are on the booking. After the call you send a fixed-fee quote from your phone, with a deposit on it. Two hours later the client accepts it from the link and pays the deposit by card on the same page.
Mid-morning, you turn last week's accepted quote into an invoice. Its deposit is already paid, so the invoice bills only the balance, and it goes out with a Pay Now link. Then you duplicate last month's two retainer invoices, change the dates and send them.
Before you close the laptop, you look at the home screen: your quote conversion over the last 90 days and how concentrated the month's billings are across your top clients. Worth knowing.
No spreadsheets, and the overdue reminders go out on their own: one $29-a-month tool in place of three.

One day, written by itself, an illustrated day of an Australian consulting practice run on OneBookPlus
An illustrated day, not real customer data. Scroll through it from morning to 5pm: the AI receptionist answers and books a missed call, the work runs from the app, the GST invoice is sent on the spot, payment lands and the books balance themselves, a review invite is queued for the next daily run, and the day closes with the ledger already written.
8:00am
While you're with a client
The growth-strategy call you'd have missed.
Riverside Logistics needs a growth strategy and wants to start this month. They call the consultant they found on Google: you.
AI Receptionist
Answered mid-workshop, discovery call booked.
The AI Receptionist app answers, books an 11:00 am discovery call and sends the booking confirmation, while you keep running the workshop.
On the discovery call
You walk in already briefed.
Ingrid's record is open with the AI's summary of the call: what Riverside needs, the budget she mentioned and when she wants to start.
Straight after lunch
Stage one invoiced between meetings.
Stage one of the Harbour Freight review is done, so its invoice goes out from your phone with a Pay Now link.
While you're back on delivery
Paid, and the books are up to date.
The card payment is recorded against the invoice, and the $250.00 GST on it is in your BAS figures.
Reviews without the awkward ask
The review request, after the workshop.
Last week's workshop booking was marked complete, so the review request email went out on the delay you set. No chasing, no awkward ask.
The day closes itself
A discovery call booked, an invoice paid.

Frequently asked questions
Common questions about practice management software for AU consultants.
Does OneBookPlus support both fixed-fee and time-based billing?
Fixed fees, yes: put the fee on a quote, take a deposit when the client accepts, and invoice the rest, with an invoice for each stage if the work runs in stages. Hourly work is different: OneBookPlus does not track time for consultants, so the hours go on the invoice as a line at your rate. If you track time in another app, keep doing that and copy the totals across.
Will OneBookPlus replace my project management tool?
Honest answer: no. OneBookPlus is the money side of an engagement: the quote, the deposit, the invoices, the bookings and the client record. It does not manage tasks or deliverables, and we don't pretend to, so most consultancies keep Asana, Linear or Notion for the work itself and use OneBookPlus to win the work and get paid for it.
How is this different from Bonsai, HoneyBook or Plutio?
Bonsai, HoneyBook and Plutio are freelancer all-in-ones built around US workflows, and some of them do things OneBookPlus does not, such as time tracking and signed contracts. OneBookPlus is built for Australian businesses: GST is worked out on every quote and invoice, your ABN prints on both, the GST and BAS reports are built in, and Stripe Pay Now takes AUD without conversion fees. It also runs your discovery call bookings and keeps one record per client with every quote and invoice on it.
Can I run this as a small consultancy with associates?
Yes. Each plan includes a set number of logins: 3 on Starter, 5 on Plus and 10 on Growth ($69/month), so each associate signs in with their own account and you choose what they can see and change. OneBookPlus does not track each person's time or hourly rate for consultants, so an associate's hours go on the invoice as a line.
Is accepting a quote really one tap?
Yes. The quote is a link. The client opens it, reads the scope, price and terms, and taps Accept, and OneBookPlus records the date and time and tells you straight away. If the quote asks for a deposit and you take card payments, the client can pay it on the same page. Accepting does not capture a name or a signature, so if an engagement needs a signed contract, sign that in a separate tool.
Does it handle GST and BAS for AU sole-trader consultants?
Yes. GST is worked out on every quote and invoice and your ABN prints on both. The GST and BAS reports are on every plan, Free included, so you or your accountant can prepare the BAS from them and lodge it through the ATO portal. If you are not registered for GST, say so once in your business details and new quote and invoice lines go out without it.
Will it work for a consultant who travels and lives in their email?
Yes. OneBookPlus runs in the browser on any computer or phone, and there is an iPhone app. Send a quote from a hotel lobby, see overnight who has accepted, and send invoices from the train. Your home screen shows what is owed, what is overdue and the quotes still waiting on an answer.
How do I move from Bonsai, HoneyBook or Plutio?
Export your clients as a CSV from your old tool and import them into OneBookPlus. Leave unpaid invoices in the old system to collect, and raise new invoices in OneBookPlus from your switch-over date so there is a clean line. Re-create any open quotes in OneBookPlus and send them from there. Retainers are billed by duplicating last month's invoice, and clients pay from the invoice link, so no card details move across from your old tool.

Read the founder bioHow this page was researched
The compliance and licensing statements above are taken from the bodies this page links to, including the AASB, the Institute of Managers and Leaders and the Federal Register of Legislation, so you can read the rule rather than take our word for it. Plan prices come from the OneBookPlus price registry, so the page and the checkout cannot disagree. Everything said about OneBookPlus describes what the product does today, and the page says so where it does not do something.
How OneBookPlus works for a consultancy
Consultancies live or die by two numbers: how fast a quote turns into accepted work, and how quickly that work turns into paid invoices. Most consultants run on a patched-together stack: Bonsai or HoneyBook for proposals (US-first, GST is an afterthought), Xero for invoicing, HubSpot for the CRM and Calendly for discovery calls. OneBookPlus puts the quoting, invoicing, client records and bookings in one place, built for Australia: GST worked out by default, your ABN checked against the Australian Business Register when you set up, BAS reports built in, and Stripe Pay Now in AUD without conversion fees.
The platform follows a piece of work from first call to paid invoice. Prospects book a discovery call through your branded booking page, and your intake questions capture the problem and the budget before the call. You send a quote with the scope, fees and terms, and ask for a deposit if you want one. The client accepts from the link and, if you take card payments, pays the deposit on the same page. When the work is done you turn the quote into an invoice for the balance, raise an invoice for each stage of a fixed fee, or duplicate last month's invoice to bill a retainer. OneBookPlus does not track time for consultants, so hourly work goes on the invoice as a line with the hours and your rate. Invoices go out with your ABN, GST and a Pay Now link, and automatic reminders chase anything overdue.
The numbers that matter
Your home screen shows what is owed and what is overdue, the quotes still waiting on an answer, and your quote conversion over the last 90 days. It also breaks the month's billings down by client and warns you when one client passes 40% of them, or your top three pass 75%, so dependence on a single account is visible before they leave.
Getting started
Sign up for free, no credit card. Add your ABN, GST registration status and your services with their prices (strategy, advisory, implementation, retainer support). Import your client list from a CSV or LinkedIn export. Set up your online booking page and drop the link into your email signature. The free plan runs unlimited one-off bookings, with up to 250 client contacts, 10 invoices and 5 quotes a month, enough to test on real engagements before committing.
