A product is bought in a store, paid for and taken home. A few days later, the price suddenly seems excessive or the purchase looks like a bad decision. Must the retailer take it back and refund the money?
A recent discussion in Paraguay's Reddit community about such a case quickly turned into an argument about foreigners, prices, invoices and Paraguayan business culture. More interesting than those accusations is the legal question underneath: many comments mixed up a retailer's voluntary return policy, statutory consumer rights and the tax rules governing invoices.
That distinction largely determines whether a buyer in Paraguay can actually demand money back.
Case 1: Bought in a store and changed your mind later
A customer who buys a defect-free product in an ordinary physical shop and later simply changes their mind does not find a general statutory right in the Paraguayan consumer rules reviewed by Pytagua to undo the purchase for that reason alone.
This differs from countries or retail chains with generous return policies. If a supermarket, electronics retailer or clothing shop voluntarily promises returns within seven, 15 or 30 days, that is initially the retailer's own policy. If that condition was offered as part of the sale, however, it may itself become binding. Paraguay's Consumer and User Protection Law No. 1334/1998 states that an offer binds the supplier during its period of validity.
Without a defect, inaccurate description or promised return policy, “I changed my mind” after a normal in-store purchase is therefore a substantially weaker position than in certain online or off-premises transactions.
Case 2: The product is defective or not what was promised
The situation changes when the problem is not the buyer's decision but the product itself.
Law No. 1334/1998 on Consumer and User Protection protects, among other things, the right to clear information and to receive the advertised product or service at the promised time, quantity, quality and price.
A defect, refusal to honour a warranty, inaccurate characteristics or a service not delivered as agreed can therefore become a genuine consumer-rights case. Depending on the facts, repair, replacement, performance or reimbursement may be relevant. A refund is not automatically the only remedy for every defect.
Consumers should preserve evidence of the defect, serial number, purchase date, photographs or video, advertising and any previous repair attempts.
Case 3: Ordered online but received something different
Electronic commerce has an additional rule.
Article 17 of Law No. 4868/2013 on Electronic Commerce requires suppliers to provide a refund mechanism when the product or service received differs from what was advertised in timing, quantity or quality. The consumer generally has no more than five business days after receipt to make the claim.
If Model A was ordered and Model B arrived, the invoice alone should not be the only evidence kept. Save the original advertisement or product page, order confirmation, delivery date and photographs of what was received.
Case 4: Bought online and simply changed your mind
For an electronic transaction, the law goes further. Article 30 of Law No. 4868 provides a withdrawal right within a maximum of five business days after receiving the product or service. A simple electronic notification of the intention to withdraw is sufficient.
This is different from a defect. Under the statutory conditions, the consumer can withdraw from the electronic transaction without proving that the product was faulty. The product or service must generally not have been used or deteriorated. The consumer may have to bear the cost of returning goods or of services already performed.
Article 31 also contains exceptions, including customised goods, products that deteriorate quickly, certain opened media products and some services booked for a specific date.
Five or seven business days? Even the official information conflicts
There is an unusual trap here. The published text of Law No. 4868 states clearly in Article 30 that the maximum period is five business days.
However, the Secretaría de Defensa del Consumidor y el Usuario (SEDECO), Paraguay's consumer protection authority, published an online-shopping warning in January 2025 telling consumers that they had seven business days to exercise the right of withdrawal.
Pytagua could not identify a corresponding amendment to the five-day wording in the statutory sources reviewed. A consumer who wants to preserve the right should therefore not rely on the longer figure and should communicate an electronic withdrawal within the five business days stated in the law whenever possible.
Case 5: A contract made away from the business — a different seven-day rule
There is indeed a seven-day rule, but it applies to another situation.
Article 26 of Law No. 1334 gives consumers seven days to withdraw when a contract was concluded away from the supplier's business premises, particularly by telephone or at the consumer's home. The period runs from signing the contract or receiving the product or service. Timely withdrawal and the condition of the product or service remain relevant to reimbursement.
This is not a general seven-day return right for purchases concluded normally at a shop checkout.
Ticket, factura and RUC: three things frequently confused
The Reddit debate exposed a second source of confusion. Several participants argued, in effect, that without a named tax invoice or a Paraguayan tax number, a complaint or refund was essentially impossible.
That is too broad.
In its official frequently asked questions, SEDECO expressly lists either a factura or ticket de compra as supporting documentation for a consumer complaint. The authority also expressly states that Paraguayan and foreign individuals or entities may qualify as consumers when acquiring or using goods or services as the final recipient.
The Registro Único del Contribuyente (RUC), Paraguay's taxpayer registry, should also not be confused with consumer status. A final consumer does not have to be registered in the RUC merely to receive protection under consumer law.
What about an electronic invoice issued without the buyer's name?
This is where the tax side becomes more technical.
For electronic invoices, the Sistema Integrado de Facturación Electrónica Nacional (SIFEN), the national electronic invoicing system administered by the Dirección Nacional de Ingresos Tributarios (DNIT), Paraguay's tax authority, expressly provides an Evento de Nominación, or nomination event.
Article 33 of Decree No. 872/2023 provides for the issuer to identify the recipient of an initially unnamed electronic invoice before certain electronic complementary documents are issued against it.
The system's technical documentation expressly covers a recipient who is not a taxpayer. Identification options include a Paraguayan identity card, passport, foreign identity card and residence card.
For this electronic procedure, therefore, the claim that “without a RUC the invoice cannot be assigned to anyone” is too broad. That does not mean every retailer's point-of-sale system will automatically handle every situation. The fiscal procedure for reversing or adjusting a transaction and the legal question of whether the consumer has a right to a refund are two separate issues.
A store voucher is not always the same as a refund
Store credit also has to be placed in the correct legal context.
If a retailer accepts a defect-free product back purely as a gesture of goodwill, its voluntary policy may provide store credit rather than cash, provided it did not promise something else at the time of sale.
If the facts instead create a statutory entitlement to reimbursement of the amount paid, the retailer cannot automatically turn that legal entitlement into a voluntary voucher arrangement. Once again, the reason for the return determines the applicable remedy.
What buyers should keep after a purchase
- the factura or ticket de compra;
- card or bank-transfer payment evidence;
- order confirmation and delivery date;
- advertising, product page or price quotation;
- warranty conditions;
- photos or videos of defects or discrepancies;
- written communication with the supplier;
- for electronic tax documents, where available, the document's control code or QR code.
The important question comes before “Can I get my money back?”
The practical mistake is treating every unwanted purchase as the same type of “return”.
For an ordinary in-store purchase, simply changing one's mind may depend on the retailer's voluntary policy. A defect or broken promise can instead trigger consumer rights. Online purchases can create additional refund and withdrawal rights. Contracts concluded away from business premises follow yet another rule.
And an unnamed invoice or the absence of a RUC number does not by itself answer any of those questions. Proof of purchase, consumer rights and the fiscal correction of the sale are connected, but they are not the same thing.
