Are you wondering whether your online store needs a cash register? This question often troubles beginner e-commerce entrepreneurs. The answer is not straightforward, but don’t worry – in most cases, you don’t need to be concerned. Read our guide to find out when a cash register is mandatory and when you can do without it.
Online Store and Cash Register – When Is It Necessary?
Generally, online stores conducting mail-order sales are exempt from the obligation to have a cash register. However, there are exceptions to this rule, depending on several factors:
- The amount of annual revenue;
- The type of goods or services sold;
- The method of delivery and payment.
If your annual revenue exceeds a specified limit, you may be required to have a cash register. However, in many cases, issuing invoices is sufficient and serves as a convenient alternative for e-commerce businesses.
Conditions for Cash Register Exemption
Does an online store need a cash register? The short answer is that online stores can be exempt from the obligation if they meet specific conditions:
- Sales are primarily made to private individuals who do not conduct business activities or to flat-rate farmers;
- Sales are made exclusively to businesses with invoices issued – in this case, the exemption may apply regardless of revenue.

Note: Some goods and services, such as electronic devices (RTV) or perfumes, always require registration with a cash register, regardless of turnover.
Mail-Order Sales and Cash Register Requirement
Mail-order sales, which form the foundation of most online stores, enjoy special privileges. You are exempt from the obligation to register sales in a cash register if:
- The goods are delivered directly to the customer via postal services, a courier company, or your own transport;
- Payment is made via bank transfer.
However, offering in-person pickup or cash-on-delivery payment may affect the requirement to have a cash register. In such cases, carefully monitoring transaction types and their values is essential.
Sales Documentation in an Online Store
Although online stores typically do not need a cash register, proper documentation of sales is necessary. Issuing invoices is a key element, as they serve as the primary form of documentation for mail-order sales.
The obligation to have a cash register in e-commerce depends on:
- Annual revenue – if yearly earnings exceed 200,000 PLN, a cash register may be required;
- The type of goods or services sold – certain products must always be registered with a cash register.
Otherwise, it is possible to maintain sales documentation exclusively through invoices.
A Personalized Invoice as an Alternative to a Receipt
For many online stores, a personalized invoice is an excellent alternative to a standard receipt. Here are its benefits:
- Eliminates the need to invest in a cash register;
- Ensures full compliance with tax regulations;
- Contains all necessary transaction details, including buyer information;
- Preferred by customers, especially for business purchases;
- Simplifies the process of handling returns and complaints.

- Easier archiving and document management;

Obligations of an Online Store Owner
Since we have answered the question “Does an online store need a cash register?”, it is worth mentioning the responsibilities of an e-commerce store owner. Running an online store comes with a series of obligations that must be met to operate legally.
Sales Record-Keeping and Providing a Bank Account
As an online store owner, you are required to maintain your own transaction records. This should include:
- Order number;
- Transaction date;
- Purchase value;
- Customer details.
Another important aspect is providing customers with a bank account for payments. Transactions made via bank transfer, combined with mail-order sales, usually exempt stores from the obligation to register sales with a cash register (unless the revenue limit is exceeded or the store sells goods that require mandatory receipts).
Consequences of Losing the Right to a Cash Register Exemption
Losing the right to a cash register exemption can have serious consequences for an online store owner. The effects include:
- The need to quickly adapt to new legal requirements;
- The obligation to purchase and register a cash register;
- The necessity to train staff in operating a cash register;
- Additional costs;
- Potential temporary disruptions to store operations.
Failing to comply with the cash register requirement can lead to severe consequences:
- Financial penalties imposed by tax authorities;
- Loss of the right to deduct VAT;
- A negative impact on the company’s finances.
