Key takeaways

5
  • OneBookPlus is agency management software for Australian marketing, creative, digital, PR and content agencies (1 to 20 people), proposals, retainers, project pipeline, time tracking, CRM and GST-compliant invoicing. From $0/mo (Free), $29/mo (Starter), $69/mo (Growth, AUD).
  • Industry-typical agency management fee on managed media spend is 10% to 20% of the media buy (e.g. a $50,000/month Meta + Google Ads budget produces $5,000 to $10,000/month of agency fee revenue on top of the pass-through cost). OneBookPlus tags media pass-through separately from fee revenue on invoices so revenue reporting reflects what the agency actually earns, not the gross media volume routed through it.
Show 3 more
  • Monthly retainer billing should be recognised over the service period per AASB 15 / IFRS 15. OneBookPlus tracks both cash-received and accrual-basis revenue so your management accounts and statutory financials reconcile cleanly.
  • GST is charged on agency fees and on the on-charge of media spend to AU clients. OneBookPlus calculates 10% GST on every invoice line, including media pass-through, with ABN displayed and BAS-ready export built in.
  • Industry-typical agency utilisation benchmarks: 65% to 75% billable hours for production roles (designers, copywriters, strategists); 35% to 55% for senior account/leadership roles. OneBookPlus tracks time per team member against those rates, so under-utilisation surfaces on the dashboard before it hits the P&L, per-role utilisation rollups are on the roadmap.

Everything for the agency

Built for how agencies actually run

Retainers, projects, proposals, time, concentration risk and CRM, the operational layer you need, without the PSA-suite price tag or the bloat that comes with mid-market tools.

Retainer Invoicing On Schedule

Monthly retainer + project work + media-spend pass-through on one branded invoice. Recurring schedule fires GST-compliant invoices automatically, set once, never miss a 1st-of-the-month send.

Scope-Of-Work Proposals

Build a proposal with deliverables, milestones, fees and terms. Client accepts on their phone, the project opens automatically, kickoff brief drops into the workspace, retainer schedule fires.

Project + Retainer Pipeline

Active retainers, in-flight projects, pending proposals on one board. Budget, hours used, next milestone per engagement, drag to update, owner per lane, value rolled up.

Team Time Tracking

Per-team-member timers logged to retainers and projects. Senior strategists, juniors and contractors all on different billable rates. Utilisation rollups show who's billable, who's slammed, who has capacity.

Client CRM with Engagement Timeline

Every client with every proposal, project, retainer, invoice, note and email on one timeline. When a client account-manager hands over, the new lead picks up everything in one screen.

Top-Client + Concentration Risk

Dashboard surfaces top clients by month-revenue with a concentration-risk callout when one client crosses 40% of billings, so you spot dependency on a single account before they churn.

Website included

A website for your agency, 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 agency 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 9pm and books a chemistry call for Tuesday. The intake form captures their vertical, monthly budget range and current marketing stack, so you walk into the call already knowing whether it's a $4k or $15k/month conversation.

  • Prices up front

    90-day brand sprint from $12,000. Monthly performance retainer from $4,500. 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 'marketing agency in [suburb]' there is a page that says what you do and where.

No card needed to start.

The Build with AI wizard in the Website Studio at its Plan step, headed Your plan is ready: chips for six services in Western Sydney, Get a quote, five pages and the Classic professional look, a note that the first AI site build is included with the plan, the home sections the AI designed (hero, features, process steps, blurb box, icon list, gallery, FAQs and a call to action), the planned menu, and a Build it button.

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.

From chemistry call to paid

How OneBookPlus works for an agency

Four steps from chemistry call to invoiced retainer, designed around how AU marketing agencies actually deliver and bill.

1
Step 1

Prospect books a chemistry call

New business books a discovery slot through your booking page. Intake form captures vertical, budget range and current marketing stack.

2
Step 2

Send a scope-of-work proposal

Build a proposal with deliverables, milestones, retainer amount and project fees. Client accepts on their phone: the engagement opens automatically.

3
Step 3

Deliver and track time

Team timers log activity to retainers and projects. Pipeline shows where every engagement sits. Billable hours and outstanding balance per client roll up to the dashboard as work accumulates.

4
Step 4

Invoice on schedule

Monthly retainer fires automatically. Tick off the milestones you've delivered and bill them together in one action. Media-spend pass-through reconciles separately. All GST-compliant, all branded.

Schedule your first retainer, Free

Most agencies send their first scope-of-work proposal within an hour of signup

Example walkthrough

Monday, the retainer run goes out

An illustrative walkthrough of a typical agency billing day

It is the first of the month, so the retainer schedule fires on its own. Every client on a monthly retainer gets their invoice without you touching it, which means no missed sends and no apologetic email about forgetting to bill.

Mid-morning there is a chemistry call with a prospect who booked through your agency booking page. The intake form already captured their vertical, their budget range and the marketing stack they run today, so the call starts at the useful part. You scope a pilot project and a retainer, draft the proposal, and send it from your phone after the meeting.

At lunch you run the top-clients view. One account has crept up as a share of monthly billings and the concentration-risk callout flags it, which puts diversification on the partner-meeting agenda before an account churns rather than after. The quote conversion figure over the last ninety days sits next to it.

Later in the week the prospect signs, and the pilot project and retainer are set up from the accepted proposal. Outstanding invoices narrow to the slow payers, and automated reminders chase them for you. Average days-to-pay is tracked against your terms, so you can see whether the trend is moving the right way.

One day, written by itself, an illustrated day of an Australian marketing agency 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.

8:30am

While you're in a workshop

The launch-campaign lead you'd have missed.

A SaaS founder needs a launch campaign. He rings the first agency on Google, yours, while you're mid-whiteboard with a client.

AI Receptionist

Answered mid-whiteboard, discovery booked.

The AI answers in two rings, books a discovery call for 11:30 and emails the intake form, before your workshop wraps.

On the discovery call

Vertical, budget and stack, already captured.

The lead card has it all: vertical, budget range, current stack. You scope a 90-day pilot on the call itself.

Between meetings

Proposal signed, invoice sent.

He accepts by lunch. One tap turns the proposal into a GST invoice with a pay link, no spreadsheet, no late-night admin.

While you're on client work

Paid, and the pilot deposit is banked.

The pilot deposit lands, the books update themselves, and $250.00 GST is set aside for BAS.

Reputation on autopilot

The review ask, once the pilot is underway.

Two hours after payment the AI asks your newest client for a review, timed to the delay you set. No chasing, no awkward ask.

The day closes itself

A workshop run, a pilot signed.

You ran a workshop and signed a pilot. The book did the rest.

Frequently asked questions

Common questions about management software for AU marketing agencies.

How does OneBookPlus handle media-spend pass-through?

You add media-spend as a line on the invoice, typically with a markup percentage your client has agreed to in the SOW (10% to 20% is industry-typical for managed-media services). Pass-through is tagged so you can separate fee revenue from media volume when you export to your accounting tool; full per-project P&L is on the roadmap.

Can I run different retainer tiers for different clients?

Yes. Each retainer is per-client, set the monthly amount, included hours/deliverables, true-up policy and renewal terms in the proposal. The recurring invoice schedule is per-engagement, so a $4,000/month retainer client and a $12,000/month retainer client both run cleanly side by side.

Does OneBookPlus replace Asana or Monday for the agency?

Honest answer: no. OneBookPlus is the commercial layer of the agency, proposals, retainers, project pipeline-by-stage, time tracking, invoicing, client CRM. It doesn't replace Asana/ClickUp/Monday for task management or creative review-and-approval flows, and we don't pretend to. Most agencies keep their PM tool and use OneBookPlus for the money side. The pipeline view tracks engagement status (proposal, in-delivery, invoiced), not individual production tasks.

How is this different from Teamwork, Accelo or HubSpot Agency Hub?

Teamwork and Accelo are mid-market agency suites with project-management depth and a price tag to match. HubSpot Agency Hub is a CRM layer on the marketing automation suite. OneBookPlus is the modern, lean alternative for small-to-mid agencies (1 to 20 people) who want proposals + retainers + project pipeline + invoicing in one tool, AU-first, from $29/month. We do not pretend to be a full PSA suite, we are the practice-side stack without the bloat.

Does it integrate with the ad platforms (Meta, Google Ads)?

OneBookPlus has Google Ads management as an installable app for agencies that resell media, at $99/mo on top of your plan. Direct Meta API integration is on the roadmap; today, most agencies report media spend manually as a line item on the monthly retainer invoice, which keeps the books cleaner anyway. Pass-through is tagged separately from fee revenue so your reporting stays honest when you export to Xero or MYOB.

Can I give clients a portal to see deliverables and invoices?

Yes. Each client has a portal showing their outstanding invoices, deliverables in progress and project status. They can pay invoices online via Stripe (AUD, no conversion fees). It cuts the “where are we up to” emails substantially.

Will it scale to a 10 to 20 person agency?

Yes. The Growth plan ($69/month) covers 10 logins, with extra logins at $9/mo each, and people you roster but who never sign in are free and unlimited. On top of that: role-based access (account managers see their clients only, partners see everything), per-team-member time tracking, per-timekeeper billable rates (senior strategist vs producer on the same project), and outstanding-receivables rollups. Above 20 people, you start needing dedicated PSA capability, talk to us about it.

How do I migrate from Teamwork, Accelo or another PSA?

Clients and contacts import from a CSV, every PSA exports them. Active retainers we recommend re-creating in OneBookPlus on a clean 1st-of-month switchover so the recurring schedule has a clean start date; the historical retainer ledger stays in your old tool for audit. In-flight projects can be either re-created (if the team prefers a fresh slate) or carried forward as engagements with start-date backdated. Stripe customer records migrate without forcing a re-card. Most 5 to 10 person agencies are operational within a fortnight; the trickiest piece is usually agreeing internally on what to leave behind versus carry forward.

How this page was researched

The compliance and licensing statements above are taken from the bodies this page links to, including the AANA, the AASB and Ad Standards, 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 an agency

Marketing agencies make money two ways: a retainer that bills predictably every month, and project work that bills on milestones. Most agencies (sub-20 people) run this on an awkward stack, Teamwork or Accelo for projects (mid-market price tag), HubSpot for the CRM, Calendly for chemistry calls, Toggl for time, Xero for the actual invoicing. OneBookPlus collapses that into one platform with the AU-first details built in: GST on every line including media pass-through, ABN validated against the Australian Business Register, BAS-ready export, Stripe Pay Now in AUD.

The platform is designed around the agency operating model. Prospects book a chemistry call through your branded booking page, intake captures vertical, budget and current stack. You build a scope-of-work proposal with deliverables, milestones, retainer amount and project fees; the client signs electronically and the engagement opens with the kickoff brief attached. As your team works, timers log to retainers and projects per team member at their own billable rate, with the engagement rate as a fallback, senior strategist, account manager and producer all bill at their configured per-timekeeper rates. The retainer schedule fires monthly invoices automatically; delivered project milestones get billed together in one action when you say go; media pass-through reconciles as a separate line so your fee-revenue margin stays honest.

Margin and utilisation that matter

The dashboard surfaces top clients by month-revenue with a concentration-risk callout when one client crosses 40% of billings, or your top three exceed 75%, so dependency on a single account becomes visible before they churn. Quote-to-invoice conversion (90d) sits next to it, alongside time-tracked-today rolling from your team's timesheets. Per-engagement P&L is on the roadmap, not in today's dashboard; what's shipped is the leading indicators that matter for retainer-led agencies: concentration, conversion, billable hours, outstanding receivables.

Getting started

Sign up for free, no credit card. Add your team, set per-role billable rates, define your service types (strategy, creative, paid media, content, SEO, PR, whichever fits the agency). Import your client list from a CSV or HubSpot export. Set up your booking page and drop the link in your new-business email signature. Most agencies are operational within an hour. The free plan supports up to five active clients with unlimited invoices, enough to test on a real retainer cycle before committing. Above five clients, the Starter or Growth plan covers the full agency.
