Everything in one place
Eight modules, one shared database. Open any module to see exactly what it does and how it replaces the tool you're paying for.

How we compare
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
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
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.
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.
Online bookings with deposits, customer history and rebooking reminders, plus the payments and BAS side handled in the same place.
One place for your client list, proposals, invoices and follow-up — instead of a spreadsheet, a calendar tool and a separate accounting login.
Table and menu management, POS sales and supplier invoices that all feed the same accounting and reporting, not three disconnected systems.
Why one platform
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
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.
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.
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.
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.
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.
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.
