Everything in one place
Every tool your business runs on
Eight modules, one shared database. Open any module to see exactly what it does and how it replaces the tool you're paying for.
See how the modules connect on the full OneBookPlus features hub, read the dedicated accounting and finance module page, or see how the two most-used modules work together on the booking software overview.
The actual product
Four modules, straight from the app
Screenshots captured from OneBookPlus itself — the job board, an invoice, the bookings calendar, and the Profit & Loss report, all reading from the same database.
Jobs on a drag-and-drop pipeline
Every job from quote to paid on one board. Drag a card between lanes and the status updates — the same record the invoice and the customer's history read from.
A GST tax invoice with a Pay Now link
Line items, 10% GST, your ABN, and a Stripe payment link on a branded document. When it's paid, the customer record and the accounting update in the same moment.
The bookings calendar
Day and week views of every booking. Each one already belongs to a CRM contact, so converting a completed booking to an invoice needs no re-typing.
Profit & Loss from every module
The P&L report with a cash/accrual toggle and comparative columns — fed by the same invoices, bookings, and expenses shown above, not a CSV import.
How we compare
One app vs five separate tools
The usual small-business setup stitches together an accounting tool, a booking tool, a CRM and a marketing tool — none of which share a customer list. Here's what changes when they're one app.
| Feature | OneBookPlus | 5-tool stack | Spreadsheets |
|---|---|---|---|
| Single shared customer database | Yes | No | No |
| Booking auto-creates a customer | Yes | No | No |
| Quote converts to invoice in one click | Yes | Yes | No |
| Native 10% GST & ABN tax invoices | Yes | Yes | No |
| Marketing to your paying customers | Yes | No | Yes |
| One login & one bill | Yes | No | No |
| No Zapier / CSV sync between tools | Yes | No | No |
| Price | From $29/mo | $150–250/mo | Free + hours |
Stop overpaying
How much are you spending on software?
Most small businesses stitch together 4-6 tools that don't talk to each other. Here's what that typically costs.
Who it's for
Who all-in-one business software fits
All-in-one business software fits any Australian SMB that's tired of paying for — and reconciling — five tools that don't talk to each other.
Tradies & home services
Quote on site, book the job, invoice on completion and take the GST out of the picture — one app from the ute, no office stack.
Salons, clinics & wellness
Online bookings with deposits, customer history and rebooking reminders, plus the payments and BAS side handled in the same place.
Freelancers & consultants
One place for your client list, proposals, invoices and follow-up — instead of a spreadsheet, a calendar tool and a separate accounting login.
Cafes, restaurants & venues
Table and menu management, POS sales and supplier invoices that all feed the same accounting and reporting, not three disconnected systems.
Why one platform
All-in-one isn't a bundle — it's one database
Plenty of vendors call themselves "all-in-one" while really bundling separate products behind one bill — each still with its own customer list, synced over an API that occasionally falls out of step. The problem with the typical Australian small-business stack was never the subscription total; it was the data flow. A booking made in one tool doesn't create a customer in your accounting tool, a paid invoice doesn't update the contact in your CRM, and your marketing tool can't tell a paying customer from a churned lead.
OneBookPlus modules share the same database. The customer who books is the same record the CRM holds, the same payer whose tax invoice the accounting module reconciles, and the same contact the marketing module emails. A "customers who haven't booked in 60 days" segment is one query, not a CSV export-import cycle. An invoice on a completed booking is automatic, not a copy-paste between systems.
That's why every module ships on every plan — Free, Starter ($29/month), Plus ($49/month) and Growth ($69/month). Plan tiers limit volume (invoices per month, team members, storage) rather than gating which modules you can use. See OneBookPlus pricing for the per-tier limits, or explore the full features hub to see how each module works.

FAQ
About all-in-one business software
What is all-in-one business software?
All-in-one business software combines the tools a small business normally buys separately — bookings, invoicing, quotes, a customer database (CRM), accounting, job tracking and marketing — into a single app with one login and one shared database. OneBookPlus is built this way: a booking creates a customer, the customer can be invoiced on the spot, and the payment flows into your accounting without copy-pasting between systems.
Why use one app instead of five separate tools?
Separate tools each keep their own customer list, so the data drifts: a booking made in Calendly doesn't appear in Xero, a paid invoice doesn't update the contact in HubSpot, and your marketing tool can't tell a paying customer from a churned lead. You end up paying for CSV exports, Zapier workflows or duplicate data entry to glue them together. One app removes the glue — every module reads and writes the same records.
Is OneBookPlus all-in-one business software made for Australia?
Yes. It's built in Melbourne for the Australian market: native 10% GST, ABN-validated tax invoices, AUD-only Stripe payments, BAS-ready summaries, AEST timezone defaults and Australian English throughout. It isn't a US product with an AU veneer bolted on later.
Do I have to use every module?
No. Use only what you need today. If you just want invoicing, the booking and marketing modules stay out of your way. When you later turn on bookings or marketing, the customer data already in your CRM flows straight through — there's no migration or re-import.
How much does all-in-one business software cost?
OneBookPlus starts free, with paid tiers from $29/month. Every plan includes all the modules — plan tiers limit volume (invoices, bookings, team members, storage) rather than locking modules behind upsells. A typical stack of five separate SaaS tools runs $150–250/month, so consolidating usually costs less while removing the integration overhead. See the pricing page for current per-tier limits.
Can I move my existing data and tools across?
Yes. You can import contacts and invoices, keep issuing tax invoices the same day, and connect Stripe for payments. Because every module shares one database, you replace tools one at a time without breaking the others — start with invoicing, add bookings, then switch off your old marketing tool when you're ready.
