Siglo BPO Report | June 2026

In 2026, if your invoice is not electronic, your invoice does not exist. We have just mapped the status of electronic invoicing in the 12 countries where we operate and as a result, the landscape is unequivocal: there is no turning back. Indeed, what began as a fiscal modernization project has become a real-time surveillance infrastructure. In other words, tax authorities in the region no longer wait for the taxpayer's declaration; on the contrary, they now see it as it is being generated.

Colombia

DIAN Pre-validation · UBL 2.1

Each invoice needs the CUFE (Unique Electronic Invoice Code) from the DIAN before reaching the buyer. Therefore, any inconsistency in VAT rates, purchaser data, or expired numbering generates automatic rejections. It is worth noting that this system has been a pioneer in the region since 2019 and also integrates electronic payroll and supporting documents into the ecosystem.

Global trends

From «getting statements» to «seeing everything in real-time»: The 5 trends defining 2026

What is structurally changing

Pre-validation and real-time validation: First, Colombia, Ecuador, and Spain already require the tax authority to validate or receive the receipt before or at the time of its issuance. Not afterward, not in batches, not when it's convenient for the taxpayer.
Multibase Automatic Crossings On the other hand, TRIBU-CR in Costa Rica, SIRE in Peru, and FEL in Guatemala cross-reference billing data with VAT, income tax declarations, and monthly reports. As a result, inconsistencies generate alerts without human intervention.
Total exception removal: Likewise, Argentina will eliminate the last ones in July 2026. The direction is clear: all commercial operations will be electronic, regardless of size, sector, or jurisdiction.
Full cycle control In the same way, Spain (RD 238/2026) already requires reporting not only the issuance but also the acceptance, rejection, and effective payment of each invoice. In other words, the tax authorities want to see the live invoice → payment flow.
Fiscal Artificial Intelligence Finally, Mexico (EFOS), Colombia, and Peru are implementing AI algorithms to detect patterns of evasion, simulated operations, and high-risk taxpayers. In this context, electronic invoicing is the primary input for these systems.

🌎 CIAT Data

According to the Inter-American Center of Tax Administrations, Latin America is the world's pioneering region in electronic invoicing. In fact, their model inspired implementation in Italy (2019), India, South Korea, and now across the European Union. In other words, electronic invoicing has ceased to be a fiscal requirement. Today, it functions as an economic intelligence infrastructure that allows for real-time sectoral and geographical monitoring.

Multi-country risks

What happens when your system isn't integrated

Companies operating in multiple countries face a specific challenge: each jurisdiction has its own technical standard, its own tax authority, and its own validation rules. Consequently, operating with non-integrated systems or manual processes in this environment is no longer simply an operational inconvenience; on the contrary, it has become an active tax risk.

The 6 most frequent risks

Expired digital signature: First of all, each country requires its own certificate with an expiration date. If it expires without renewal, all billing stops. In fact, this happens more often than it should.
Incompatible formats: For example, Colombia uses UBL 2.1, Ecuador uses XML with XAdES-BES, Mexico uses CFDI 4.0, and Spain requires EN16931. Therefore, a single ERP without specific localization cannot handle all these formats.
Number ranges exhausted Both in Colombia (DIAN) and the Dominican Republic (DGII), resolutions have ranges and validity dates. Consequently, if they are exhausted or expire, the invoice is invalid
Automatic sanctions without notice: In particular, Panama and Guatemala apply automatic fines without a grace period. This means that a technical error can generate a penalty before the team becomes aware of it.
Crosses that reveal inconsistencies: Furthermore, if the electronic invoice does not match the VAT return, income tax return, or the monthly report, the authority detects it automatically. And the request arrives without delay.
Irretrievable loss of tax credit: Finally, in Guatemala, an invoice not reported for two months definitively loses its credit. Similarly, in Ecuador, a document not transmitted in real-time lacks tax validity.

What to do

How to operate in 12 jurisdictions without losing control

The solution is not to have 12 different systems or 12 local providers with different standards. Instead, the key is to have a single team that knows the 12 regulations and that, moreover, it operates on platforms with certified localizations for each country.

What a well-managed operation should guarantee

Updated tax locations in each country: fees, XML formats, transmission protocols and validation rules updated with each regulatory change
Digital certificate monitoring with early expiry alerts in all jurisdictions, so that no signature expires without renewal
Offline contingency for countries with real-time transmission (Ecuador, Spain): automatic resend queue when connection is restored
Pre-declaration conciliation In countries with automatic crossings (Costa Rica, Peru, Guatemala): ensure billing, VAT, and income match before submitting.
Centralized numbering range management to prevent them from running out or expiring without notice (Colombia, Dominican Republic)
A single technical and regulatory contact for the 12 countries, instead of coordinating with multiple local providers

At SigloBPO, we operate our clients' electronic invoicing directly from SAP Business One, Oracle NetSuite, QuickBooks, and Odoo, with certified localizations for each of the 12 countries. Ultimately, it's not just about issuing receipts, but about ensuring that each invoice complies with local regulations, is transmitted within legal deadlines, and, above all, is consistent with associated tax filings.

In how many of these 12 countries does your company operate?

We'll show you how to centralize the electronic billing for your entire regional operation with a single team and a single service standard.
