Your Sydney cafe runs on Square, your wholesale arm runs on invoices, and the two never meet in one number
A custom POS system for a Sydney business runs $70k to $160k and 4 to 8 months. You build once Square, Toast, or Lightspeed can't handle your real counter: account-based wholesale pricing alongside retail tap-to-pay, integration with your inventory and accounting, and reporting that ties every channel together. The Sydney trigger is a multi-site hospitality or retail business where off-the-shelf POS fees and rigid workflows no longer fit how you actually trade.
The cafe and retail front run on Square; tap-to-pay is smooth, the hardware is neat. Then the wholesale side needs account pricing and net terms, the second site has different products, and none of it reconciles into one set of numbers because Square wasn't built for your full operation. You export from POS, export from the wholesale system, and merge them in a spreadsheet to know what the business actually did.
Square, Toast, Lightspeed, and Clover are genuinely good for a single straightforward venue, and you shouldn't replace them lightly. The friction starts when you run multiple sites, mix retail and wholesale, need deep inventory and accounting integration, or hit transaction fees that scale painfully with volume. For a Sydney hospitality or retail group, a POS that can't unify accounts, channels, and reporting forces manual work behind every busy trading day.
Budgeting a pos build in Sydney
| Project scope | Typical cost | Timeline |
|---|---|---|
| Core custom POS with payments and inventory link | $70k to $100k | 4 to 5 months |
| Add multi-site, wholesale accounts, and offline mode | $100k to $135k | 5 to 7 months |
| Full accounting integration and consolidated reporting | $135k to $160k | 7 to 8 months |
The case for owning your pos
A custom POS is built for your full operation: retail tap-to-pay and account-based wholesale on one system, multi-site product and pricing logic, and native integration with inventory and accounting. Instead of merging exports in a spreadsheet, you get one set of numbers across every channel and site, with payment processing you control rather than fees that scale against you. The till finally matches how the business actually trades.
- You run retail and wholesale and need both on one till
- Multiple sites don't reconcile into one set of numbers
- Transaction fees at volume rival the amortised cost of a custom build
- POS doesn't integrate with inventory and accounting, forcing manual reporting
- You run a single straightforward venue Square or Toast serves well
- You don't need account-based wholesale pricing
- You value plug-and-play hardware and processing over control
- You need to be trading in days, not months
What your build should include
What we build under POS in Sydney
The engagements Sydney teams bring us most often: point of sale software, retail POS, restaurant POS, Square alternative, Toast alternative and Clover.
Delivery, week by week
Exactly what you get
A POS built for your whole operation, not a single counter: retail tap-to-pay and account-based wholesale on one system, multiple sites reporting into one set of numbers, and a sale that updates inventory and the books in real time. It keeps trading offline if the connection drops mid-service, handles payments PCI-compliantly, and ends the spreadsheet merge that currently tells you what the business did. The till finally matches how you actually trade.
How to choose a developer in Sydney
Hire a team that can speak concretely about PCI compliance, offline reliability, and payment processing, because a POS that fails at lunch rush is lost revenue. Ask how one till serves both retail and wholesale. A Sydney developer who works with hospitality and retail groups will understand multi-site trading, busy-period reliability, and local payment expectations. Connect the POS to an inventory management system, a custom CRM (Customer Relationship Management), accounting, and business intelligence dashboards from one team so every channel reports into one truth.
- Retail and wholesale on one POS, with account pricing and net terms alongside tap-to-pay
- Multi-site product, pricing, and reporting unified into one set of numbers
- Native inventory and accounting integration, ending the manual export-and-merge
- Payment processing arrangements that control cost as volume grows
- Reporting that ties sales, stock, and revenue across every channel in real time
- Square and Toast ship polished hardware and payment processing you'd otherwise assemble
- POS must be rock-solid; downtime at a busy counter is lost revenue and frustrated staff
- Payment processing and PCI compliance add real complexity to a custom build
- For a single simple venue, an off-the-shelf POS is cheaper and faster
- !A vendor vague on PCI compliance; ask exactly how they handle card data and certification
- !No offline mode plan; ask how the till keeps trading if the connection drops mid-service
- !They ignore wholesale accounts; ask how one POS serves both retail and account pricing
- !No inventory or accounting integration; ask how a sale updates stock and the books
- !They can't speak to reliability; ask what happens to revenue if the POS goes down at lunch rush
If pos is on the roadmap, supply chain, business intelligence dashboards, booking & scheduling usually follow within the year. Budget them as one conversation.

Frequently asked questions
Why build a POS instead of using Square or Toast?
Square and Toast are excellent for a single straightforward venue. You build custom when you run retail and wholesale on one till, operate multiple sites that won't reconcile, hit transaction fees that scale painfully, or need deep inventory and accounting integration the off-the-shelf tools can't provide. The case is operational complexity, not dissatisfaction with the hardware.
How does a custom POS handle PCI compliance?
By using a certified payment processor and tokenization so card data never touches your systems directly, plus the access controls and logging PCI DSS requires. A serious build designs compliance in from the start rather than retrofitting it. This complexity is a real reason custom POS costs more, and why you should never hire a vendor vague about it.
What happens if the internet drops mid-service?
A well-built custom POS has an offline mode that keeps taking sales and queues transactions, syncing when the connection returns. For a busy Sydney venue, this is essential: a POS that stops trading during a connection drop at lunch rush costs real revenue. Confirm any vendor's offline strategy before signing.
Can it run retail and wholesale together?
Yes, that's a common reason to build. One system handles retail tap-to-pay and account-based wholesale pricing with net terms, so both channels report into one set of numbers. Off-the-shelf POS tools force you to run wholesale separately and merge the results manually, which is exactly the friction a custom build removes.
Does it integrate with our inventory and accounting?
It should. A sale updates stock in real time and takings reconcile to your accounting with GST handled correctly, so you're not exporting and merging in a spreadsheet. Tight integration with inventory and accounting is the difference between a POS that's a till and one that's the operational hub of a multi-channel business.
