Assistance Needed – Integration with Local E-Invoicing Provider and QuickBooks

[RAGAS]

Hi everyone,

I am currently using Loyverse as my point-of-sale system and would like to request guidance and technical support regarding an integration setup.

My goal is to integrate Loyverse with:

A local electronic invoicing provider authorized by the Ministry of Finance in El Salvador (for compliant electronic tax invoices), and an accounting ERP such as QuickBooks for automated bookkeeping, VAT tracking, and financial reporting.

Below is the intended data flow:

CLIENT
   │
   ▼
LOYVERSE
(Sales, services,
customers, pricing)
   │
   │  Sale data
   ▼
SMARTBILL
(Electronic invoicing
authorized by the Ministry of Finance)
   │
   │  Authorized electronic invoice (DTE)
   ▼
QUICKBOOKS
(Accounting, VAT,
financial reports)

Specifically, I would appreciate your support with:

*Available APIs, webhooks, or supported integrations to export sales and customer data from Loyverse.

*Best practices or recommended partners for integrating Loyverse with third-party e-invoicing platforms

*Existing or supported methods to connect Loyverse with QuickBooks (directly or via middleware)

Thank you in advance for your assistance. I look forward to your guidance so we can implement this integration correctly.
