Square rings a coffee fine; it can't take a Windsor tooling deposit or sell greenhouse peppers by the pallet
A custom POS or point-of-sale build for a Windsor specialty seller runs $30,000 to $85,000 and 3 to 5 months. Square, Toast and Clover nail fixed-price retail and restaurants. They struggle with progress deposits on custom work, case-and-pallet pricing for greenhouse produce, USD-priced cross-border sales, and the inventory tie a trade or wholesale counter actually needs.
You run a counter that isn't a coffee shop. Maybe it's a trade counter taking a deposit on a custom job, or a greenhouse outlet selling peppers by the case to a buyer who'll resell across the river in USD. Square wants a fixed-price product and a single tap. It has no clean way to take a 30% deposit now and the balance on pickup, or to price the same product per-unit, per-case and per-pallet.
And cross-border pricing trips it up. A US buyer paying in USD, with the exchange and any duty handled, is normal here and awkward in a stock POS. So you end up running the till in Square and tracking deposits, case pricing and USD sales in a notebook beside it. The POS handles the simple sale and you handle everything that makes your counter different.
- You take deposits on custom or made-to-order work
- You price the same product by unit, case and pallet
- Cross-border USD sales are a regular part of business
- Your POS and inventory don't talk to each other
- You sell fixed-price retail or run a standard restaurant
- No deposits, case pricing or cross-border sales apply
- Square or Toast already covers your counter cleanly
- Volume doesn't justify a custom build
- Progress deposits and balance tracking for custom and made-to-order sales
- Unit, case and pallet pricing for the same product
- Cross-border USD pricing and exchange handled at the till
- Live inventory tie so every sale updates real stock
- One system instead of a stock POS plus a deposit notebook
- Costs more than a Square or Clover terminal subscription
- Payment processing and hardware integration add scope
- Overkill for a simple fixed-price retail counter
- You own updates and PCI considerations the big platforms handle

Exactly what you get
A till that matches a Windsor specialty counter: deposits and balances on custom work, the same product priced by unit, case or pallet, USD cross-border sales handled cleanly, and a live tie to inventory so stock stays honest. The result is one POS that replaces the Square-plus-notebook workaround. It connects to inventory management software, accounting software for the books, and an ERP if your group runs production behind the counter.
How to choose a developer in Windsor
Find a builder who asks how you take money before they pick a payment processor. Deposits, multi-unit pricing and cross-border USD are the make-or-break details here, so ask to see each handled in a demo. Confirm they'll integrate inventory and accounting so the till isn't an island, and make sure they take PCI and payment security seriously. A trade or wholesale POS reference beats a coffee-shop one every time.
Timeline: what happens, and when
- !They treat every sale as fixed-price; ask how deposits work
- !No multi-unit pricing; ask how case and pallet pricing is handled
- !They ignore cross-border USD; ask how a US buyer pays
- !No inventory integration; ask how stock stays accurate
- !No PCI plan; ask how payment data is handled securely
Most Windsor 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
Why can't Square handle our counter?
Square is built for fixed-price retail and restaurants. It struggles with progress deposits on custom work, pricing the same product by unit, case and pallet, and cross-border USD sales. A Windsor trade or greenhouse counter hits all three, so it ends up tracking them in a notebook beside Square.
Can a custom POS take deposits on custom work?
Yes. It records a deposit now and the balance on pickup or delivery, tracking the open balance against the order, which stock retail POS systems handle poorly if at all.
How does it handle US buyers paying in USD?
A custom POS prices in USD with exchange handled at the till and any duty accounted for, so cross-border sales are clean rather than a manual workaround beside the terminal.
What does a custom POS cost in Windsor?
A POS with deposits and multi-unit pricing runs $30k to $48k. Add cross-border and inventory integration for $48k to $68k, and full ERP and accounting integration reaches $85k.
Will it keep our inventory accurate?
Yes. A custom POS ties each sale to your inventory system so stock updates in real time, which prevents the drift you get when a stock POS and your inventory live separately.
