Point of Sale: Your Guide to Choosing the Best POS Software for Your Business

Point of Sale (POS) is no longer just a cash register used to calculate purchase values and print receipts. It has become an integrated system that connects sales with inventory, accounting, customers, branches, payment methods, and reports. When a single sale is recorded, the system can update the product quantity, record the tax, specify the payment method, save the invoice data, and display the transaction within the sales, shift, and branch reports.

The importance of a POS system increases as the business expands, the number of items and employees grows, or inventory and cash discrepancies begin to appear. Choosing a limited or unsuitable software can lead to slow sales, price discrepancies, difficulty matching payments, and a lack of knowledge of true profits.

This guide explains what a POS is, how POS software works, its components and types, the most important required features, and how to link it with accounting, inventory, and electronic invoicing, in addition to the criteria for choosing the best POS software for stores, restaurants, and companies in Saudi Arabia.

What is Point of Sale?

Points of sale are the systems and devices used to complete a product or service sale, record its data, collect its value, and issue the associated invoice.

The term POS comes from the English phrase Point of Sale. A point of sale may refer to the place where the customer pays, such as a cashier counter, but it is currently used to denote a system that includes:

• Sales management software.
• Cashier machine.
• Barcode scanner.
• Receipt printer.
• Cash drawer.
• Customer display screen.
• Electronic payment device.
• Products and prices database.
• Inventory management.
• Reports and accounting.

POS software converts the sales process into a digital record that can be tracked and reviewed. Instead of entering the price and calculating the total manually, the system retrieves the product data, applies the tax and discount, then records the payment method and issues the invoice.

POS systems are generally defined as software that combines the hardware and software used to record transactions, collect payments, monitor inventory, issue invoices, and prepare reports.

How does a POS system work?

A POS system works by recording order details and then executing a set of interconnected operations once the invoice is approved.

The sales cycle usually begins as follows:

1. The cashier logs into the system.
2. Reads the product barcode or searches for it by name or code.
3. The system retrieves the price, tax, and available quantity.
4. The employee adds the requested products or services.
5. The system applies the permitted offers and discounts.
6. The customer or employee specifies the payment method.
7. The system issues the invoice.
8. The sold quantity is deducted from the inventory.
9. The transaction is added to the branch and shift sales.
10. The system records the transaction's impact on accounting when there is accounting integration.

These steps may seem simple, but the system's power appears in the details. For example, when executing a return, the software should not only refund the amount but also return the quantity to the inventory if it is fit for sale, and record the return's impact on sales, tax, payment method, and the customer's account.

If it is a credit sale, the system can record the amount in the customer's account instead of considering it cash in the drawer. When using more than one payment method for the same invoice, the amount must be accurately distributed among cash, card, transfer, or other methods.

Components of a POS System

A POS system consists of the software that manages operations and the hardware used by the employee and customer during the sale.

POS Software

The POS software is the part responsible for saving product, customer, price, sales, user, and report data.

Its basic functions include:

• Creating sales invoices.
• Searching for products and reading barcodes.
• Managing prices and discounts.
• Supporting multiple payment methods.
• Recording returns.
• Opening and closing shifts.
• Setting user permissions.
• Updating inventory.
• Monitoring branch performance.
• Extracting sales reports.
• Linking with the accounting system.
• Supporting electronic invoicing when needed.

Not all POS software is equal; some do not go beyond issuing invoices, while others offer comprehensive management of sales, inventory, purchases, customers, and accounting.

Cashier Machine

The cashier machine is the device or screen on which the POS software runs. It could be:

• A desktop computer.
• A touch screen.
• An All-in-One device.
• A tablet.
• A mobile phone or portable device.
• A self-service kiosk.

The device must be suitable for the volume of operations and operating hours, because a slow device during rush hours directly affects the speed of customer service.

Barcode Scanner

The barcode scanner helps retrieve the product quickly and reduces errors caused by manually typing codes or prices.

The barcode must be linked to accurate data, including:

• Product name.
• Unit of measurement.
• Selling price.
• Tax.
• Inventory.
• Department or category.

The business may also need more than one barcode for the same item if it is sold in different units, such as a piece and a carton.

Receipt Printer

Used to print the invoice or sales receipt. The required printer varies based on:

• Invoice size.
• Print speed.
• Business type.
• Paper width.
• Connection method.
• The need to print a logo or QR Code.

The print quality of the QR code must be tested, especially for establishments subject to electronic invoicing requirements.

Cash Drawer

Used to store cash amounts, and it may open automatically after completing a sales transaction. No employee should be able to open it without authorization or without recording a transaction.

Customer Display Screen

The customer screen displays products, prices, discounts, and the total while the invoice is being prepared. It helps to:

• Increase the transparency of the sales process.
• Discover errors before payment.
• Display promotional offers.
• Improve the customer experience.

Payment Devices

The payment device may work independently or be linked to the POS software to send the invoice value automatically. Direct integration reduces entering incorrect values into the payment device or recording an incorrect payment method in the system.

Types of POS Systems

POS systems are divided into several types according to the operating location, data storage method, and type of device used.

Traditional POS System

The software is installed on a device or server inside the facility, and data is stored locally or within the branch network.

It may be suitable when:

• The business operates in a single location.
• There is an unstable internet connection.
• The facility has a technical team.
• You need continuous local operation.

However, managing multiple branches or monitoring reports remotely may require additional setups and networking.

Cloud POS System

The cloud system operates via the internet, and data is managed on the service provider's or hosting provider's servers.

Its features include:

• Accessing reports from outside the branch.
• Unifying branch data.
• Centralized updates.
• Ease of adding users.
• Reducing the need for a local server.
• Centralized management of prices and products.

Facilities that need to monitor accounting and branches remotely can obtain the best cloud accounting system in Saudi Arabia from Aamalsoft for Software Solutions.

Mobile POS

Operates on a mobile phone or tablet, and is suitable for:

• Sales representatives.
• Exhibitions and events.
• Restaurants.
• Pop-up stores.
• Delivery services.
• Selling within store departments.

Support for printing, payment, synchronization, and permissions must be ensured.

Self-Service POS

Allows the customer to choose the product or meal, execute the order, and pay through a self-service kiosk.

These systems are common in:

• Quick-service restaurants.
• Cafes.
• Cinemas.
• Retail stores.
• Service centers.

They help reduce congestion, but their success depends on interface simplicity and accurate integration with inventory, the kitchen, and payment methods.

Type	Key Features	Challenges	Suitable For
Traditional System	Local operation and internal infrastructure control	Managing branches and updates	Fixed store or branch
Cloud System	Centralized management and remote access	Reliance on connection	Multi-branch companies
Mobile POS	Flexibility and ease of movement	Limitations of some devices	Representatives and events
Self-Service	Reducing congestion and speeding up orders	Requires an easy interface	Restaurants and retail

Importance of POS for Stores and Companies

The importance of POS lies in connecting the moment a product is sold with the rest of the facility's operations, rather than leaving cashier data isolated from inventory and accounting.

Among the most important benefits:

• Speeding up the sales and payment process.
• Reducing pricing and calculation errors.
• Monitoring sales in real-time.
• Knowing the performance of each employee or cashier.
• Controlling offers and discounts.
• Tracking returns and cancellations.
• Managing employee shifts.
• Reconciling cash and cards.
• Updating inventory automatically.
• Comparing branch performance.
• Identifying top-selling products.
• Analyzing the most profitable products.
• Supporting electronic invoicing.
• Maintaining a transaction history.

For example, a store might achieve high sales but not know which products generate real profit.

An integrated accounting system allows comparing the selling price with the product cost, discounts, and returns, providing management with a more accurate picture than relying on total sales alone.

Features of the Best POS Software

The best POS software is not the one with the highest number of tools, but rather the system that fits the daily work cycle and offers the necessary functions easily and accurately.

Fast Sales Interface

The cashier should be able to:

• Access products quickly.
• Read barcodes.
• Search by name or code.
• Add more than one unit.
• Suspend an invoice.
• Retrieve a previous order.
• Change quantities.
• Apply discounts according to permissions.
• Complete payment in limited steps.

A complex interface increases wait times and raises the probability of error, especially when hiring new employees or during rush seasons.

Product and Price Management

The system should support:

• Product categories.
• Barcodes.
• Units of measurement.
• Purchase and selling prices.
• Multiple prices.
• Value-added tax (VAT).
• Cost.
• Available quantities.
• Minimum inventory level.
• Expiration dates when needed.
• Serial numbers.
• Sizes and colors when needed.

Offers and Discounts Management

The system must allow creating offers according to clear rules, such as:

• Discount on a product.
• Discount on the invoice.
• Percentage or amount discount.
• Buy a certain number and get an extra product.
• Limited-time offer.
• Special price for a customer group.
• Vouchers.
• Loyalty program.

It must be defined who can create, modify, or apply a discount so that offers do not turn into a source of revenue leakage.

Multiple Payment Methods

It is preferable for the software to support:

• Cash.
• Cards.
• Transfers.
• Digital wallets.
• Credit sales.
• Mixed payment.

Each amount must appear in the correct payment method report to facilitate reconciling shift sales with cash, payment devices, and bank accounts.

Returns Management

The software should allow linking the return to the original invoice and specifying:

• The returned product.
• The quantity.
• The reason for the return.
• The product's condition.
• The refund method.
• The employee who executed the transaction.
• The transaction's impact on inventory and tax.

Permissions and User Log

An independent account must be created for each employee instead of sharing a single account.

Among the permissions that should be controlled:

• Changing prices.
• Granting discounts.
• Executing returns.
• Canceling invoices.
• Opening the cash drawer.
• Viewing costs.
• Seeing profits.
• Modifying inventory.
• Exporting reports.
• Closing a shift.

Difference Between a Cashier Machine and a POS System

A cashier machine is one of the physical components used during a sale, while a POS system is the overarching architecture that manages the process, data, and reports.

Comparison Element	Cashier Machine	POS System
Definition	The device used at the sales counter	Software, hardware, and database
Main Function	Running the sales interface	Managing sales, inventory, and accounting
Data Storage	Depends on the installed software	Centralized database
Reports	Not generated by the device alone	Provides sales and performance reports
Inventory Management	Not available without software	Available when there is an inventory module
Branches	Just a device inside the branch	Can link branches together
Permissions	Not managed by the device alone	Manages users and actions
Invoicing	Requires invoicing software	Issues invoices through the system

Therefore, it is not enough to buy a high-spec device if the software does not support the operations the business needs. A powerful software also requires hardware suitable for the transaction volume and operating hours.

Importance of Linking POS to Inventory

Linking POS to inventory helps update the product quantity with every sale or return, and reduces reliance on manually entering sales into another software.

The benefits of integration include:

• Knowing available quantities.
• Reducing the sale of out-of-stock products.
• Receiving low-stock alerts.
• Identifying stagnant products.
• Monitoring item movement.
• Managing transfers between branches.
• Facilitating stocktaking.
• Calculating the cost of goods sold.
• Discovering inventory discrepancies.
• Planning purchases.

When a product is sold, the quantity must be deducted from the warehouse linked to the branch. When a saleable return is executed, the quantity is added back to the balance. If the product is damaged, it must be recorded in a separate movement so it does not appear within the available quantity.

An accounting system from DigitalPro offers features to monitor inventory, product movement, manage suppliers and warehouses, along with analyzing sales, items, and profitability.

Importance of Linking POS to Accounting

Linking POS to accounting leads to recording the financial impact of the transaction without manually re-entering sales totals.

Upon completing a sales invoice, the system can record:

• Sales revenue.
• Value-added tax (VAT).
• Payment method.
• Cash or bank.
• Customer account.
• Cost of goods sold.
• Inventory movement.
• Discounts.
• Returns.

Using an accounting system linked to POS helps unify data between the cashier, accountant, and storekeeper.

Smart reporting software can also be relied upon to monitor invoices, returns, employee performance, inventory, revenues, and expenses through centralized reports. The portal page illustrates support for monitoring sales, financial statements, inventory, and customer and supplier account statements.

POS and Electronic Invoicing in Saudi Arabia

Facilities subject to electronic invoicing must use a technical solution that issues and saves invoices electronically and systematically according to the applied requirements.

The Zakat, Tax and Customs Authority (ZATCA) clarifies that an electronic invoice is issued and saved via an electronic system; a handwritten or scanned invoice is not considered an electronic invoice. Invoices are also divided into tax invoices and simplified tax invoices.

Regarding points of sale, one must verify support for:

• Simplified tax invoice.
• Tax invoice when needed.
• Value-added tax (VAT).
• Serial number.
• QR code.
• Saving invoices.
• Credit and debit notes.
• Integration with the Fatoora platform when the facility enters the second phase.
• Configuring invoicing devices and units.
• Processing accepted and rejected invoices.

The second phase of electronic invoicing began gradually on January 1, 2023, and requires linking the taxpayer's invoicing systems to the Fatoora platform after notifying the targeted facility at least six months before the linkage date.

Therefore, it is not enough to settle for the phrase "ZATCA compliant." One must test issuing the invoice, the return, the QR code, and the integration process on actual branch devices.

POS Software for Restaurants

A restaurant needs specialized POS software because the sales process is not linked only to products, but to tables, the kitchen, recipes, delivery, and order types.

It is preferable for restaurant POS software to support:

• Dine-in orders.
• Takeaway orders.
• Delivery.
• Table management.
• Transferring and merging tables.
• Splitting the invoice.
• Adding order notes.
• Routing items to kitchen stations.
• Kitchen Display Systems (KDS).
• Electronic waiter.
• Digital menu.
• Self-service kiosks.
• Recipe management.
• Calculating meal costs.
• Monitoring waste.
• Integration with delivery apps.
• Sales reports by order channel.

An accounting system for restaurants and cafes from DigitalPro provides a touch-supported sales interface, internal order management, takeaway and delivery, tables, splitting invoices, routing orders to the kitchen, and supporting KDS systems.

In addition to tools for monitoring inventory, meal costs, sales reports, and profits.
