Product details

What is AquaPOS?

AquaPOS is a Windows desktop point-of-sale application built by Keen Systems for food and beverage businesses — restaurants, cafés and counter-service venues — with an integrated module for venues that also manage pool or leisure access, such as swimming pools, aquatic clubs and recreational facilities.

At its core, AquaPOS is a complete restaurant billing system. Staff take orders across Dining and Takeaway modes, send tickets straight to the correct kitchen or bar station, print bilingual bills, hold and split bills, and close every shift with a fully reconciled cash register. Behind the till, managers get full product, purchase, staff and reporting control — everything a real front-of-house and back-office team needs, in one offline-capable desktop application.

For venues that also run a pool, the same system adds hourly and slot pricing, adult and child tickets, and team packages that can bundle in restaurant items — so a single bill can cover a pool session and a meal without switching software.

A clear daily overview — today's revenue, pool vs. restaurant sales split, open bills, payment methods and hot-selling items.

Product capabilities

Complete restaurant billing, built for real service

Dining, takeaway & multi-mode billing

Switch between Restaurant, Dining and Take Away modes on one unified billing screen, with a live cart and running total.

Barcode & item-code search

Find any product instantly by scanning a barcode or typing its item code — no digging through category menus during a rush.

Split bill payments

Split one order into two separate bills in a click, so shared tables and groups can pay separately without re-entering items.

Hold & resume bills

Hold an in-progress order and jump straight to another — held bills stay listed with a live count until a cashier resumes or clears them.

Configurable service charge

Turn a restaurant service charge on or off, set its percentage, choose whether it prints on the receipt, and override it per bill when needed.

Bilingual bills & kitchen tickets

Print customer bills in English or Sinhala per bill, each item shown in its own translated name, while kitchen tickets follow your configured system language.

Unified billing — Restaurant, Dining and Take Away modes with barcode search, held bills and split bill, all on one screen.

Product capabilities

Multi-kitchen KOT / BOT ticket printing

Any number of kitchen or bar stations

Set up Main Kitchen, Bar, Dessert Counter or any station you need, each with its own assigned printer.

Automatic per-kitchen routing

When a bill has items from more than one station, AquaPOS prints a separate KOT/BOT to each kitchen's own printer, headed with that station's name.

Live kitchen updates

Only the newly added or changed items print when an order is amended, instead of reprinting the whole ticket.

Per-item kitchen notes

Add a note to any line — "no sugar", "extra spicy" — so special requests reach the right kitchen printer.

Configure any number of kitchen or bar stations, each with its own printer — KOT/BOT tickets route there automatically.

Product capabilities

Advanced product management & costing

Items with unlimited variants

Manage restaurant, pool and service items with size or option variants (e.g. Small / Medium / Large), each with its own price and barcode.

Per-item and per-variant cost price

Record a cost price on every item and variant, feeding directly into restaurant profit reporting — revenue minus product cost minus expenses.

Categories & stock tracking

Organise the catalog into categories, track stock where it matters, and control overselling behaviour for the whole business.

Purchases & supplier tracking

Record purchases against suppliers to restock items, with a running, filterable purchase history by supplier, status and payment method.

Product catalog with size variants, assigned kitchen station and category, all searchable and filterable.

Product capabilities

Complete cash register & staff management

Full register session control

Open a register with a starting float, add or remove cash mid-shift, and close with an expected-vs-actual reconciliation.

Precise cash reconciliation

AquaPOS calculates the exact expected cash in the drawer from the opening float and cash sales, and flags any variance immediately.

Full register session history

Every past shift — date, cashier, bill count, revenue and status — stays on record, searchable by cashier or date.

Role-based staff accounts

Add staff with their own PIN login and one of three roles — Super Admin, Admin or Cashier — each with a clear, pre-defined scope.

Granular permissions

Choose exactly which screens each role can see, and require a manager PIN for sensitive actions like voiding a bill, cancelling an order, or reopening a paid bill.

Cash reconciliation and restaurant profit, calculated automatically from sales and recorded product cost.

Questions and answers

Frequently asked questions

What businesses is AquaPOS designed for?

AquaPOS is designed for swimming pools, aquatic clubs, leisure venues and similar operations that combine pool access, timed sessions, services and restaurant or counter sales.

Does AquaPOS work as a restaurant POS?

Yes. The implemented restaurant workflow includes dining and takeaway modes, item categories and variants, stock tracking, configurable service charge, kitchen routing and receipt or kitchen-ticket printing.

Can AquaPOS manage pool pricing and packages?

Yes. Administrators can configure hourly rates, slot duration, grace time, adult and child tickets, team packages, included restaurant items and additional per-person charges.

What reports are included?

The application includes sales summaries, restaurant item performance, profit and loss, register sessions, bill history and void-bill reporting, together with payment and cash-reconciliation views.

Is the installer downloaded directly from this page?

The download button is configurable by Keen Systems. While a customer installer URL is not yet assigned, it opens the AquaPOS contact request so licensing and deployment can be confirmed.

Is AquaPOS cloud based?

AquaPOS is a Windows desktop application with a local operational database and backup tools. Any deployment, networking or integration requirements should be confirmed with Keen Systems for the intended venue.

Can AquaPOS print bills and kitchen tickets in more than one language?

Yes. Bills can be printed in English or Sinhala per bill, with each item shown in its own translated name. Kitchen tickets (KOTs) print consistently in your configured system language.

How does AquaPOS handle split bills, held bills and staff access?

A live order can be split into two separate bills for shared tables, or held and resumed later without losing it. Every staff member logs in with their own PIN under a Super Admin, Admin or Cashier role, and sensitive actions such as voiding or reopening a bill can require a manager PIN.
