SUNAT Electronic Invoicing for Clinics: Complete Peru Guide 2026

Electronic invoicing is mandatory in Peru for most taxpayers since 2021, and clinics and medical centers are no exception. However, many healthcare institutions still use generic billing systems that don't understand clinical workflows, generating double data entry, errors, and delays.

What does SUNAT require?

Mandatory electronic receipts

Receipt	Mandatory?	Healthcare use
Electronic invoice	✅ Yes	Services to companies/insurers
Electronic sales receipt	✅ Yes	Services to individual patients
Electronic credit note	✅ Yes	Cancellations and corrections
Electronic debit note	✅ Yes	Price adjustments
Electronic dispatch guide	⚠️ Depends on activity	Sample/supply transport

Technical requirements

Digital certificate issued by accredited entity (Reniec, Certidigital, etc.)
SUNAT connection via SEE (Electronic Issuance System) — can be SEE-SOL, SEE del Contribuyente, or SEE-OSE
UBL 2.1 format for XML receipts
Digital signature of the receipt with certificate
Sending and receiving CDR (Receipt Acknowledgment)

The healthcare-specific problem

Billing in healthcare is more complex than in other sectors because:

1. Multiple payers

A single service may be paid by the patient, an insurer (EPS), a corporate agreement, or SIS. Each payer has different rules.

2. Services billed after delivery

In healthcare, services are provided first and billed later. In many cases, the invoice includes multiple services from different areas (consultation + lab + imaging).

3. Complex fee schedules

Prices vary by agreement, insurer, room type, and other factors. A generic billing system doesn't handle this complexity.

Implementation options

1. SEE-SOL (SUNAT Portal)

Free but manual. Doesn't integrate with any system. For clinics with fewer than 10 invoices/day it may work, but it's tedious.

2. SUNAT Invoicer

Free SUNAT software for desktop issuance. Better than SOL but still doesn't integrate with clinical systems.

3. Generic billing software

Solutions like Nubefact, Efact, etc. Issue electronic receipts but don't understand clinical workflows. Requires double data entry.

4. Healthcare system with integrated billing

The ideal option: the commercial management module is integrated with the clinical system. When a service is registered in the HIS, the invoice is generated automatically with correct data.

Option	Cost	Clinical integration	Double entry	Automation
SEE-SOL	Free	❌ No	✅ Yes	❌ No
SUNAT Invoicer	Free	❌ No	✅ Yes	⚠️ Partial
Generic software	$30–$100/month	❌ No	✅ Yes	⚠️ Partial
Integrated system	Included	✅ Yes	❌ No	✅ Yes

Common mistakes

1. Billing from a system separate from the clinical one

If the receptionist registers the patient in the HIS and then has to re-enter data in another system for billing, there's duplication of effort and high error risk.

2. Not billing all services performed

Without integration, it's easy for a lab test or diagnostic image to be excluded from the invoice. That's money lost.

3. Not managing the insurer cycle

Peruvian insurers require specific documentation (guarantee letter, pre-authorization, settlement). A generic system doesn't manage this flow.

4. Not storing XML files correctly

SUNAT can audit receipts from up to 4 years back. Signed XML files must be stored securely and accessibly.

Frequently asked questions

Can I use SUNAT's free invoicer for my clinic?

Technically yes, but it's not practical with more than 10 daily receipts or when you need clinical system integration.

What digital certificate do I need?

A legal entity digital certificate for the clinic (not personal). Cost: $50–$150 USD/year depending on provider.

How do I handle insurer billing?

Insurers (EPS, private insurance, SIS) have specific settlement processes. A commercial management system specialized in healthcare manages the full flow: pre-authorization, service delivery, settlement, billing.

Does Davix include SUNAT electronic invoicing?

Yes. The commercial management module includes electronic receipt issuance (invoices, sales receipts, credit/debit notes) integrated with the clinical workflow, with direct SUNAT connection.

Conclusion

Electronic invoicing for Peruvian clinics requires more than a receipt issuer:

It's mandatory — SUNAT requires electronic receipts for all taxpayers.
Generic systems create double data entry — and with it, errors and wasted time.
Clinical system integration is key — automatic invoice when services are registered.
Insurers have specific flows — that generic systems don't handle.
Davix includes commercial management with integrated SUNAT electronic invoicing.
