TsatsaTayka ESIR for online sales and automatic fiscalization

TsatsaTayka online sales + ESIR

TsatsaTayka for online sales with ESIR fiscalization and
0 RSD monthly subscription when you have no turnover!

Complete workflow for online sales and automatic fiscalization through the V-PFR service of the Serbian Tax Administration. ESIR is not a separate tool for manually retyping invoices, but part of the TsatsaTayka business web system.

If you issue only a small number of fiscal documents during a month, the monthly subscription is not charged. You pay a one-time installation and initial setup fee, and the monthly package is activated only when you exceed the threshold of your chosen package.

  • additional design changes and custom pages
  • migrations, connectors, and integrations with external systems
  • special business workflows that are not part of the standard configuration

Solution value

A web shop should not do the same work twice

In a classic workflow, someone has to open an order, retype line items, enter the customer, choose payment, fiscalize the invoice, save the PDF, and send it to the customer. TsatsaTayka turns that work into a connected and controlled workflow.

I want less manual work

No manual retyping

Order, line items, amounts, and payment are taken from the system, instead of the operator entering them again in another program.

Fewer errors

The risk of wrong price, quantity, tax label, payment method, or incorrectly sent invoice is reduced.

Faster order processing

Fiscalization and invoice delivery become part of the online order processing workflow, saving time on every document.

Control and records

Requests, responses, PFR numbers, journal, QR code, and verification URL remain saved and available for review.

Main features

ESIR covers basic and advanced fiscal workflows for web sales, with control of tax rates, payment methods, V-PFR communication, and electronic invoice delivery to the customer.

Fiscalization

Prepares draft invoices, sends requests to V-PFR, and stores the fiscalized response with journal and QR code.

Tax rates

Synchronization of tax labels and rates from the V-PFR status response, without manual entry of fiscal rates.

Product catalog

Invoice line items are selected from the existing TsatsaTayka Product records, with the ability to change price, quantity, and tax label.

Special workflows

Refunds, copies, proforma invoices, training invoices, and advance closing are supported through Advance / Refund and final Normal / Sale.

Review and records

The ESIR journal stores statuses, PFR numbers, responses, tax line items, related invoices, and test records by transaction type.

Display and printing

The fiscalized invoice is displayed with the original V-PFR journal, QR code, and verification URL.

Software solution without a local fiscal device

TsatsaTayka ESIR is web/PHP software installed on a server environment and used through a browser. The solution is intended for electronic and other remote commerce, with HTTPS communication with the V-PFR service.

Application type
Web ESIR / POS software
PFR communication
V-PFR over HTTPS protocol
Technology
PHP, CodeIgniter 4, HTML, and JavaScript
Invoice delivery
Electronic display and delivery to the customer

Typical workflow

The system uses data from web sales and the ESIR journal, and before fiscalization it checks V-PFR status and active tax rates.

1

V-PFR status check

The system checks communication, certificate, PAC, and V-PFR URL before working with fiscal invoices.

2

Invoice preparation

The invoice is created from the TsatsaTayka workflow or prepared through ESIR pages using products, payment, and customer data.

3

Fiscalization

The draft is sent to V-PFR, and the response is stored with PFR number, journal, QR code, and verification URL.

4

Review and delivery

The invoice is available in the journal for review, electronic delivery, browser printing, or ESC/POS printing.

Pre-fiscalization checks

  • The invoice must have at least one line item.
  • The line item tax label must exist in synchronized rates.
  • The total payment amount must match the total invoice amount.
  • A refund cannot exceed the amount of the reference invoice.
  • V-PFR communication must be successfully verified.

Advance workflows

Advance sale uses special advance line items according to the tax label. An additional note describes the goods or services the advance applies to.

Closing an advance first creates an advance refund with a reference to the previous advance invoice.

The final invoice contains actual goods or service line items, and ESIR adds a reference to the advance refund in the additional note.

Not sure which model you need?

Send an inquiry and briefly state whether you already have a web shop, which system you use, how many orders you have per month, and whether you want only the ESIR module or the complete TsatsaTayka online shop workflow.
