Your Auckland counter serves walk-ins and trade accounts, and Square only understands walk-ins
A custom POS system for an Auckland firm runs $50,000 to $120,000 over 4 to 6 months. You build one when your counter serves both walk-in retail and trade-account customers, and Square or Lightspeed only models the cash sale. Account-based pricing, GST-correct invoicing, and tying a sale to incoming container stock are exactly where off-the-shelf POS leaves Auckland trade counters short.
Your Auckland trade counter takes cash from walk-ins and runs accounts for builders and contractors, and Square treats every transaction like a coffee sale. So your staff run trade orders on a separate system, key account pricing by hand, and can't tell a customer whether the stock they want is on the shelf or still on a container, because the POS has no link to inventory in-transit.
Square, Toast and Clover are built for fast retail checkout. An Auckland trade-and-retail business needs the POS to hold account customers, apply negotiated pricing, issue GST-correct invoices on terms, and know whether stock is landed or inbound, which the standard hospitality-and-retail tools simply don't do.
Budgeting a pos build in Auckland
| Project scope | Typical cost | Timeline |
|---|---|---|
| Unified retail + trade till | $50,000 to $78,000 | 4 to 5 months |
| Add account pricing + GST invoicing | $78,000 to $102,000 | 5 to 6 months |
| Full build with stock visibility + accounting sync | $102,000 to $120,000 | 5 to 6 months |
The case for owning your pos
A counter that serves walk-ins and trade accounts needs one POS that does both, which Square and Lightspeed don't. Custom lets you ring a cash sale and an account order on the same till, apply negotiated trade pricing, issue GST-correct invoices on terms, and check whether stock is landed or inbound, so your staff stop running two systems and re-keying every account order.
- Your counter serves both walk-in retail and trade-account customers
- Trade orders currently run on a separate system from the POS
- You need GST-correct invoicing on terms the standard POS can't issue
- The counter needs to see inbound container stock, not just shelf stock
- You run a pure walk-in retail or hospitality counter
- Square, Toast or Lightspeed handles your sales without workarounds
- You have no trade accounts or net-terms billing
- Low transaction complexity makes off-the-shelf entirely adequate
What your build should include
Auckland POS: the full scope
Everything a POS build here can cover: mobile POS, payment processing integration, custom POS system, point of sale software, retail POS, restaurant POS and Square alternative.
Delivery, week by week
Exactly what you get
A POS that runs your whole counter on one till: a walk-in pays cash and a trade account gets negotiated pricing and a GST-correct invoice on net terms, side by side. Staff can see whether stock is on the shelf or on an inbound container before promising it. Checkout stays up if the network drops and syncs on reconnect. Every sale reconciles cleanly into your accounting software and ERP, so the two-system split and the double data entry disappear.
How to choose a developer in Auckland
Choose a team that has built POS for trade counters, not just cafes. Ask how they'd ring an account order with negotiated pricing, how they issue a GST-correct invoice on terms, and what happens to the till when connectivity drops. Confirm their PCI and payment-certification plan and how the counter sees inbound container stock. Auckland trade buyers want one reliable system, so judge any partner on whether they truly unify retail and trade rather than bolting them together.
- One till for walk-in cash sales and trade-account orders, ending the two-system split
- Negotiated trade pricing and net terms applied automatically at the counter
- GST-correct invoices issued on terms, not hand-built in a separate tool
- Stock visibility showing whether goods are on the shelf or on an inbound container
- Clean reconciliation into your accounting software with no double entry
- Custom POS hardware integration and payment certification add time and cost
- You own PCI and payment-security responsibilities a SaaS POS would carry
- For a pure walk-in retail shop, Square is cheaper and entirely adequate
- Offline-resilience for a busy counter needs careful, tested engineering
- !They treat the POS as pure retail; ask how they'd ring a trade-account order
- !No GST-on-terms invoicing; ask how they issue a compliant account invoice
- !No offline plan; ask what happens to the counter when the network drops
- !Payment security is vague; ask about PCI scope and certification
- !No inventory link; ask how the counter sees inbound container stock
Most Auckland teams pricing pos end up comparing notes on supply chain, business intelligence dashboards, booking & scheduling too; the systems share one data spine.

Frequently asked questions
How much does custom POS development cost in Auckland?
Between $50,000 and $120,000. A unified retail-and-trade till starts at $50,000 to $78,000; adding account pricing and GST invoicing reaches $102,000, and a full build with inbound-stock visibility and accounting sync runs to $120,000 over 5 to 6 months.
Why not use Square, Toast or Lightspeed?
They're built for fast walk-in retail and hospitality. They fall short for an Auckland trade counter that needs account-based pricing, GST-correct invoicing on net terms, and visibility of inbound container stock, which forces staff onto a second system and constant re-keying.
Can one POS handle both walk-in and trade customers?
Yes, that's the core benefit. A custom build rings cash sales and trade-account orders on the same till, applies negotiated pricing automatically, and issues GST-correct invoices on terms, ending the two-system split that off-the-shelf POS forces on retail-and-trade firms.
Will it work if the internet drops?
It should be offline-resilient. A competent build keeps the counter taking sales when connectivity drops and syncs transactions when it returns, because a busy Auckland trade counter can't stop selling because the link to the cloud blinked.
Can the counter see inbound container stock?
Yes, with inventory integration. The POS shows whether goods are on the shelf or on an inbound container, so staff can give customers an honest answer instead of promising stock that hasn't cleared the port yet.
