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.

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 workNo 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.
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.
V-PFR status check
The system checks communication, certificate, PAC, and V-PFR URL before working with fiscal invoices.
Invoice preparation
The invoice is created from the TsatsaTayka workflow or prepared through ESIR pages using products, payment, and customer data.
Fiscalization
The draft is sent to V-PFR, and the response is stored with PFR number, journal, QR code, and verification URL.
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
