Panama: Fiscal Devices vs. Electronic Invoicing – what are the main differences for Retailers?

Panama allows fiscalization through authorized fiscal devices or the SFEP electronic invoicing system. While fiscal devices record transactions and transmit daily Z reports, electronic invoicing uses digitally signed XML documents validated by authorized PAC providers.

Panama's fiscalization framework offers two main methods for documenting commercial transactions: traditional fiscal equipment and the Panama Electronic Invoicing System (SFEP). Although both systems serve the same purpose of ensuring that sales are properly documented and reported, they differ significantly in their technical architecture, daily operations and communication with the tax authority.

The first approach relies on physical fiscal devices, while the second uses electronic invoicing software and authorized service providers. Understanding these differences is particularly important for retailers, POS developers and businesses planning to modernize their sales

Traditional fiscalization in Panama is based on DGI-authorized fiscal equipment, such as fiscal cash registers or fiscal printers connected to POS applications. During a sale, the POS sends transaction information to the fiscal device, which processes the fiscal data, calculates the relevant tax amounts, records the transaction and issues a fiscal receipt. The device includes protected fiscal and audit memory that stores transaction information, receipts and accumulated fiscal totals. One of the most important requirements is the daily Z report. At the end of the business day, the fiscal equipment generates a report containing sales totals, applicable taxes, credit notes, debit notes and other fiscal information.

Under e-invoice-SFEP, fiscalization is performed electronically rather than through a traditional fiscal printer. The POS or ERP system generates an electronic invoice in the required XML format, applies the issuer's qualified electronic signature and submits the document for validation through an authorized PAC. Once validated, the electronic invoice receives an Autorización de Uso, confirming its authorization for fiscal purposes. The system also produces a CAFE, the human-readable representation of the electronic invoice, which can be provided to customers electronically or on paper. Unlike the fiscal-device system, electronic invoicing operates primarily through structured electronic documents rather than hardware-based fiscal memory. SFEP offers two main solutions: integration with an authorized PAC and the DGI's free invoicing tool, Facturador Gratuito.

With a fiscal device, the POS communicates with the fiscal printer, and the customer receives the fiscal receipt generated by that device. With electronic invoicing, the POS prepares the electronic invoice, and the document is processed through the PAC authorization system.

In our view, the principal difference between Panama's two fiscalization models is where fiscal control takes place. With fiscal devices, compliance is centered on certified hardware, fiscal memory and daily reporting. With SFEP, it shifts toward software integration, electronic signatures, document validation and digital archiving. Electronic invoicing provides greater flexibility for businesses operating multiple stores, online sales channels or centralized POS environments. However, it also introduces new technical responsibilities, particularly around PAC connectivity, authorization monitoring and contingency management.

For established retailers, the decision to migrate should therefore consider both regulatory eligibility and the operational implications for their existing POS infrastructure.

Implementation Impact and What Businesses Should Do

The choice between fiscal devices and electronic invoicing directly affects POS architecture, sales processing, reporting and maintenance.

Businesses continuing with fiscal devices should ensure that their hardware remains authorized, daily Z reports are transmitted, fiscal memory is protected and maintenance procedures are followed.

Businesses using SFEP should implement compliant XML invoice generation, qualified electronic signatures, PAC integration, proper authorization handling and electronic storage.

POS providers should also support returns, credit and debit notes, different payment methods, customer-document delivery and applicable contingency procedures.

Retailers migrating from fiscal devices to electronic invoicing must also complete the required deregistration of their existing fiscal equipment.

The central implementation objective is the same for both models: every sale must result in a legally valid fiscal document, with reliable recording, reporting and traceability.
