Once you are set up to issue FEL (Factura Electronica en Linea), you have two options: use SAT’s free tools (Agencia Virtual and the App FEL mobile app), or subscribe to a certified provider (certificador autorizado) that offers better software, integration, and features. This guide compares the main FEL providers in Guatemala as of September 2026, checked against SAT’s official register of certificadores.
Quick summary: SAT tools are free but basic. Paid certificadores offer better UX, mobile apps, desktop software, API integration, and team features — but none of them publish a public price list, so you have to ask for a quote. For one-person service businesses, free SAT is enough. For growing companies and retail/restaurants, a paid provider saves hours per week.
Free SAT Option
Before paying for a certified provider, understand what SAT offers free:
Agencia Virtual (Web)
- Issue invoices from any web browser
- Access to your DTE history
- Free, no registration beyond your normal SAT Agencia Virtual credentials
- Limitation: basic UI, one invoice at a time, no templates, no customization, no automation
App FEL (Mobile)
- SAT’s official mobile app (iOS and Android)
- Issue invoices from your phone
- Offline mode (with sync when connectivity returns)
- Free
- Limitation: same basic feature set as Agencia Virtual
For a freelancer or solo consultant issuing 5-20 invoices per month, the free SAT option is genuinely sufficient. The main reason to move to a paid provider is speed, integration with other business systems, or features for a multi-user team.
Paid Certified Providers Compared
SAT publishes the official register of certificadores autorizados, and as of 1 September 2026 it lists 17 authorised certificadores. Anyone not on that register is not a certificador, whatever their marketing says — check the register before you sign anything. The best-known names:
1. Infile (INFILE, S. A.)
One of the largest providers. Known for stability and integration with accounting software.
- Pricing: not published — request a quote
- Free tier: limited trial available
- Web + mobile: yes, both
- API integration: yes, for developers
- Multi-user teams: yes
- Best for: small and medium businesses, accountants managing multiple clients
- Setup time: 1-2 hours
2. Megaprint (MEGAPRINT, S. A.)
Long-established provider, popular with retail and restaurants.
- Pricing: not published — request a quote
- Web + mobile: yes
- POS integration: strong, popular for retail/restaurant POS systems
- API integration: yes
- Best for: retail, restaurants, businesses with physical POS
- Setup time: 1-2 hours
3. G4S Documenta (G4S DOCUMENTA, S. A.)
Corporate-focused, strong for large enterprises with high volume. SAT’s register lists this certificador as G4S Documenta — you will still see the older “G4S Document Secure” name in third-party write-ups, but Documenta is the name to use when you contact them.
- Pricing: not published — request a quote
- Best for: medium-large corporations, high-volume invoicing
- Features: advanced compliance, audit trail, enterprise-grade security
- Setup time: 1-2 weeks for full enterprise integration
4. Ainnova (AINNOVA S.A.) — formerly GuateFacturas
The company that used to trade as GuateFacturas rebranded to Ainnova in 2023, and the old guatefacturas.com address now serves Ainnova. In its own words it was SAT’s first authorised certificador and it says it certifies the largest volume of DTEs in the country.
- Pricing: not published — request a quote
- Features: native web platform, bulk file upload, POS, and web-service integration
- Best for: small and medium businesses through to large corporates
- Setup time: 1-2 hours
5. Smaller / niche providers
The register also lists Ainnova aside, Cámara de Comercio de Guatemala, Cari Latinoamérica, Cofidi, Contap, Corposistemas, Digifact Servicios, Formularios Continuos de Centro America, GOM Solutions, Grupo CDS, Inforum Consulting, Operadora Económica and Tekra, among others. Several serve specific niches or regions. Always check the current SAT register before committing.
Comparison Matrix
| Provider | Price | Free Tier | Mobile App | API | POS Integration | Best For |
|---|---|---|---|---|---|---|
| SAT (free) | Q0 | ∞ | Yes | No | No | Solo freelancers, low volume |
| Infile | Not published | Trial | Yes | Yes | Partial | SMBs, accountants |
| Megaprint | Not published | No | Yes | Yes | Strong | Retail, restaurants |
| G4S Documenta | Not published | No | Yes | Yes | Yes | Large enterprises |
| Ainnova | Not published | — | — | Yes (web service) | Yes | SMBs to large corporates |
No Guatemalan certificador publishes a public price list. We checked each provider’s own site in September 2026 and found no published rates, so ask for a quote — pricing generally depends on your monthly DTE volume.
Which Provider Fits Your Business?
Freelancer, Solo Consultant, Low Volume (< 30 invoices/month)
Use SAT’s free tools. Agencia Virtual + App FEL give you everything you need. Paid providers do not add enough value at this volume.
Small Business, 30-200 invoices/month
Infile, Ainnova, or Megaprint. Pick based on UI preference and accounting software integration.
E-commerce or Online Store
Infile or Ainnova. Both expose an API / web service you can wire to Shopify, WooCommerce, or a custom system so invoices are generated when orders complete.
Retail Store or Restaurant with POS
Megaprint. Its POS integration ecosystem is the most developed. If you already use a POS system, ask your POS vendor which FEL provider they integrate with — usually Megaprint is on the list.
Multi-User Team / Office With Several People Invoicing
Infile or Ainnova. Both support multiple users on one account. SAT’s free tools do not have proper team support.
Large Enterprise (500+ invoices/month)
G4S Documenta or custom API integration. At high volume you need enterprise features (audit trails, compliance reports, custom workflows) that only the enterprise-grade providers offer.
Accountant Managing Multiple Clients
Infile. The strongest “accountant portal” features in the Guatemalan market — switch between client companies, batch processing, consolidated reports.
Migration and Switching
Can you change providers? Yes, easily. FEL is a certification system where all providers issue invoices under the same SAT standard. You are not locked into any provider — your DTE history is always accessible through SAT’s Agencia Virtual, regardless of which provider you use to generate invoices.
To switch:
- Sign up with the new provider
- Import your existing customer database (CSV or manual)
- Use the new provider for new invoices
- Cancel the old subscription
There is no data migration needed for the invoices themselves — they are all archived in SAT.
Integration with Accounting Software
If you use accounting software, check which FEL provider integrates:
- Alegra — integrates with Infile
- Siigo — integrates with Infile, Megaprint
- ContaPaq — integrates with Megaprint, Infile
- QuickBooks (with Guatemala module) — ask the provider whether it imports QuickBooks data directly or by CSV
- Excel/manual — compatible with all providers (copy/paste or CSV)
If you are just starting, pick the combination that your accountant is most comfortable with. Switching later is possible but adds friction.
Setup Process (Typical)
- Activate FEL with SAT first — this is mandatory regardless of which provider you later choose. See our FEL habilitacion guide.
- Choose a provider and sign up — most offer online signup with identity verification
- Connect your SAT credentials — the provider uses your SAT Agencia Virtual credentials to certify invoices on your behalf
- Test with a practice invoice — ask the provider whether it offers a test DTE before you issue real invoices
- Start issuing invoices — real invoices are certified and sent to SAT automatically
Common Questions
Are all certified providers legally equivalent?
Yes. All invoices generated through any SAT-certified provider have identical legal status. The choice is about features and user experience, not legality.
Will SAT know which provider I use?
Yes, but it does not affect your tax obligations or audit risk. Each DTE is tagged with the certifying provider.
Can I use multiple providers at once?
Technically yes, but it is a mess. Pick one and stick with it for operational simplicity.
What happens if my provider goes out of business?
Your historical DTEs remain in SAT’s Agencia Virtual permanently — they are never “lost.” You can switch to another provider immediately with no legal risk.
Do providers take a percentage of my invoice value?
No. All providers charge fixed monthly fees or per-invoice fees. None take a percentage of the invoice value.
