POS System Companies & Dealers in Hawaii (HI)

How to choose POS system companies in Hawaii

Every sale in the islands carries the general excise tax, and unlike a mainland sales tax it is charged to the business, not the shopper. That one difference shapes how a point-of-sale system should be set up here, and it is the first thing to test in a demo. The second is distance. When a terminal dies on a Friday night in Kona, it matters whether the replacement is in a Honolulu stockroom or a warehouse in Ohio.

Where to find POS system companies in Hawaii

Oahu holds most of the state's people and most of its POS dealers. Urban Honolulu is the only large metro area, and Honolulu has the widest spread of resellers, restaurant specialists and installers who keep spare hardware on hand. Outside town, providers based in Aiea, Mililani and windward Kailua usually cover much of the island.

The neighbor islands are smaller markets with fewer choices. Maui's second metro area centers on Kahului and Wailuku, and local providers also work out of West Maui's Lahaina, where businesses are still rebuilding after the 2023 fire, and upcountry Makawao. On Kauai, look to Kalaheo on the south side. Shops in Hilo and Kona are often served by Honolulu firms or mainland companies working remotely. Ask where the nearest technician actually lives, and whether an on-site visit means an interisland flight added to your bill.

General excise tax rules a Hawaii POS system has to handle

There is no sales tax in Hawaii. The GET applies to nearly all business income, services included. The standard rate is 4%, and every county now adds a 0.5% surcharge, for 4.5% in total. Wholesale sales to another business for resale are taxed at 0.5%, with no county surcharge. You can visibly pass the tax on to customers, but you are not required to. Because the amount you pass on also counts as gross income, the Department of Taxation caps the visible pass-on rate at 4.712% where the 4.5% rate applies. Hawaii also has no sales tax holidays.

On a demo or quote, check that the system can:

• Show GET as its own line at the pass-on rate you choose, or fold it into shelf and menu prices.
• Ring wholesale or resale orders at the lower rate without the county surcharge.
• Produce reports that match Form G-45, which you file monthly if you owe more than $4,000 in GET a year.

Rates and filing thresholds change, so confirm current figures with the Department of Taxation before you finalize settings.

Service charges, card fees and ID checks at Hawaii registers

Restaurants and hotels need to be careful with service charges. Under state law, a service charge on food or beverage must either go entirely to employees as tip income or come with a clear disclosure that part of it pays for other costs. In 2025 the Hawaii Supreme Court said that disclosure has to make plain whether the charge is a tip, and employees have sued over unpaid service charges. Your POS should let you edit check and receipt wording, and it should keep service charges separate from voluntary tips in reports and payroll exports.

Card surcharges are less settled. Lawmakers have introduced bills to ban surcharges on customers who pay by card, and guidance on where things stand is mixed. A cash discount offered to everyone is the more common route. Before a provider turns on any surcharge or dual pricing program, get in writing how it meets Hawaii law and card network rules, and who pays if it doesn't.

Tobacco and vape products can't be sold to anyone under 21, the sale must be face to face, and each store needs its own retail tobacco permit. Ask for an age prompt that stops the sale until the cashier confirms ID. Staff under 21 may sell or serve liquor only under conditions such as supervision, so many owners require a manager approval on alcohol rung up by younger employees.

Data is the last piece. Hawaii's breach law covers card and account numbers and requires notice to affected customers without unreasonable delay, plus a report to the state when more than 1,000 people are notified. Ask where card data is stored, whether it is encrypted or tokenized, and who handles notification if the provider's system is the one breached.

How to compare POS providers in Hawaii

Start with the clock. Hawaii doesn't use daylight saving time, so in summer a help desk that closes at 9 p.m. Eastern goes dark at 3 p.m. in Honolulu, before the dinner rush. Get support hours stated in Hawaii time.

• Hardware: Does the dealer keep loaner terminals and printers on your island, or ship from the mainland?
• References: Ask for two customers in your trade on your island, and call them.
• Contract: Check term length, early termination fees, any requirement to use their card processor, and whether equipment is leased or owned. Equipment leases are often hard to cancel.
• Setup: Find out who loads your menu or inventory and trains staff, on site or by video call.

National brands often have better software and lower hardware prices. A local reseller is usually the one who shows up. Plenty of Hawaii businesses get both by buying a national system through an island dealer, so ask each candidate what happens to your support if you later switch processors.
