    Automation of E-Invoicing in Poland: How will the latest changes in KSEF affect Salesforce?

    The growing volume of electronic document exchange and increasingly strict tax regulations make manual invoicing no longer cost-effective. As a result, e-invoicing automation will soon become mandatory for many businesses in Poland. Integrating Salesforce with the National e-Invoicing System (KSeF) is a step that not only ensures compliance with legal requirements but also streamlines everyday financial and sales processes. In this article, we explain why this solution is essential for B2B companies and how it can help boost operational efficiency.

    1. The National e-Invoicing System – What You Need to Know

    The National e-Invoicing System (KSeF) is a centralized platform for issuing, sending, receiving, and storing structured invoices—electronic invoices with a strictly defined data format (XML). In practice, this means an invoice is no longer just an image or a random PDF, but a set of fields (buyer details, line items, VAT rates, etc.) recorded according to the FA(3) schema, which has been published as the target standard.

    Using KSeF offers tangible benefits for organizations: it accelerates document workflows, reduces manual data entry errors, shortens settlement times, and facilitates automation of financial and accounting processes. For the government and tax authorities, KSeF is a tool for improving transparency in tax settlements, detecting VAT fraud more effectively, and gaining near real-time access to statistical data—enabling better fiscal control and reducing the tax gap.

    Key dates: The obligation to use KSeF will be introduced in stages—starting February 1, 2026, for the largest taxpayers (those exceeding the revenue threshold set by the Ministry of Finance), followed by April 1, 2026, for all other VAT payers. For the smallest entities (e.g., those with monthly revenue of around PLN 10,000), further deferrals are planned, potentially until January 1, 2027. This means companies have clearly defined timeframes to prepare processes, integrations, and testing before the official go-live.

    2. Is Using the National e-Invoicing System Mandatory?

    Yes—companies are required to use KSeF primarily due to legal changes. Legislators are introducing a standardized, mandatory workflow for structured invoices to reduce VAT fraud, speed up and simplify tax audits, and improve transparency (tax authorities will have faster access to data). In practice, KSeF is intended to become the “single source of truth” for electronic invoices: format standardization (FA(3)) and a central repository make it easier to automate settlements, detect irregularities, and conduct fiscal analyses.

    Non-compliance with KSeF rules will result in penalties—both financial and, in extreme cases, criminal. Proposed fines in draft regulations and analyses can reach up to 100% of the VAT amount shown on the invoice (or around 18.7% of the gross value if VAT is not listed). Additional administrative penalties are also planned (e.g., small fees for late document submission after system outages—approximately PLN 500 per invoice), along with potential consequences under the Fiscal Penal Code for issuing fraudulent invoices. For these reasons, we strongly recommend treating KSeF implementation as a top priority in compliance planning.

    3. What Do You Gain by IntegratingKSeF with Your Salesforce CRM?

    3.1 Real-Time Invoice Status in CRM

    Sales reps and customer service teams can view invoice status (e.g., accepted/rejected), KSeF reference numbers, and payment deadlines directly in Salesforce. This eliminates the need to log into accounting systems or manually check reports, speeding up customer service.

    3.2 Faster Dispute and Claim Resolution

    Access to rejection reasons and confirmations from KSeF enables immediate problem diagnosis. This allows CRM to automatically create tasks for the right people and speed up processes related to invoice handling and correction.

    3.3 Improved Accounts Receivable and Cash Flow Management

    Automatic updates on overdue invoices allow faster reminders and trigger collection processes. Finance and sales teams can coordinate proactively before issues escalate.

    3.4 Fewer Errors and Less Manual Work

    Synchronizing statuses and key fields removes the need to copy data manually between PDFs/CSVs and CRM, significantly reducing mistakes. Fewer corrections mean faster processes and lower operational costs.

    3.5 Consistent Data Across Departments

    All teams work with the same synchronized information pulled from KSeF, reducing discrepancies between sales and accounting. This minimizes escalations and accelerates decision-making.

    3.6 Sales Process Automation

    Invoice status changes in KSeF can automatically trigger actions in Salesforce (e.g., sending confirmations or creating tasks). This makes closing deals and post-sales processes smoother and more predictable.

    3.7 Better Reporting and Forecasting

    Payment status and due date data from KSeF improve the accuracy of DSO reports and cash flow forecasts in CRM. This helps finance and management make more informed planning decisions.

    3.8 Enhanced Security and Compliance

    Pulling data directly from KSeF provides an immutable audit trail and reduces operational risks associated with manual handling. It also simplifies documentation for tax audits and internal compliance checks.
