Swissdec, ISO 20022, QR-bill, GeBüV, VAT ESTV, eBill and nDSG are integrated in ewws. No third-party system, no separate license, no detour between module and authority.
Swiss SMEs have to adhere to precisely defined interfaces to banks, compensation funds, insurers, the ESTV and authorities. ewws treats these interfaces as a mandatory part of the platform and not as an add-on that can be forgotten. The overview below shows each standard with reference to the ewws implementation.
Salary reporting
The unified salary reporting procedure of Switzerland. Salary certificates, AHV, IV, EO, ALV, BVG, UVG, UVGZ and withholding tax report in one standardized XML bundle to the respective recipient. Phases 0 to 3 cover master data, wage types, monthly report and quarter as well as year-end. Phase 4 with the ESTV withholding tax tariff is configured per tenant.
Status in ewws: Phases 0 to 3 integrated, a pre-check available in the payroll workspace.
Claims reporting
Illness and accident benefit capture. Insurers receive claims UVG, UVGZ and KTG in a standardized XML structure. K0 to K4 cover master data, claim creation, lifecycle and document archive. The XML adapter to the respective insurer is configured per tenant.
Status in ewws: K0 to K4 integrated in a dedicated KLE workspace with an audit trail, K5 prepared.
Banking
Swiss banks communicate exclusively on ISO 20022. camt.053 delivers the daily bank statement, camt.054 the detailed advice. pain.001 is the payment order to the bank, pain.008 the direct debit. ewws imports camt directly, reconciles open items via amount, reference and QR-bill, and exports pain bundles at the push of a button. Remaining items land in a clarification list per tenant.
Status in ewws: camt.053, camt.054, pain.001 and pain.008 integrated with a banking cockpit.
Invoice
Since 1 October 2022, the orange and red payment slip is abolished. ewws generates QR-bills with the Swiss QR code, IBAN or QR-IBAN, QRR or SCOR reference and a complete recipient dataset. PDF output with perforation notes, receipt and payment part. Sending by mail, eBill or print.
Status in ewws: Fully integrated in sales, both creation and receipt.
Retention
The ordinance on business records per CO 957 and CO 958. Books and documents must be kept for ten years and managed traceably. ewws secures documents in an append-only archive with a hash chain. Every new entry references the hash of the previous one, tampering leaves a visible gap. The audit trail documents creation, corrections and cancellations.
Status in ewws: GeBüV document archive and audit cockpit integrated in accounting.
VAT
The Federal Tax Administration requires a VAT return per form 220 or 221, per quarter or semester, with the rates 8.1, 2.6, 3.8 percent as well as special rates. ewws supports the effective method and the net tax rate, reconciles the VAT accounts against the assessment basis and delivers the return as XML or a print form for the ESTV submission.
Status in ewws: A complete ESTV return in the accounting workspace, eVAT upload configured per tenant.
Invoice sending
The SIX eBill network routes invoices directly into the recipient e-banking. Swiss SMEs increasingly demand this, especially in B2B traffic. ewws sends invoices as eBill, receives status feedback such as opened, paid or disputed, and links the status to the open item. Recipient master data is updated via the SIX interface.
Status in ewws: Sending and status feedback integrated in accounting and sales.
Data protection
Since 1 September 2023, the revised Swiss data protection act applies. Processing on behalf, a data protection impact assessment, the right to data release and breach notification are mandatory. ewws assigns each tenant a data protection officer and a record of processing activities, documents data exports and handles access and deletion requests with an audit trail. Self-hosted operation keeps data in Switzerland.
Status in ewws: Data export, audit trail and tenant data protection fields integrated.
Compliance tools sold as separate modules risk drifting away from the main system technically and contractually. ewws treats them like accounting itself: part of the platform, not part of an optional package.
Payroll reports from the same personnel master data that is in the salary certificate and the UVG insurance. Banking reconciles documents that sales created. VAT settles accounts that accounting keeps. No file between the systems.
When the ESTV changes a rate, Swissdec extends a phase or SIX eBill introduces a new status field, the standard is updated in ewws like a mandatory migration. No separate contract for compliance updates.
An audit requires not just the data, but also the trail. Every compliance path in ewws writes its own audit line that the fiduciary or external auditor can read without a special tool.
Standards are one thing, the data behind them another. ewws runs self-hosted or with a Swiss host, not necessarily in a foreign cloud. Data sovereignty lies with you, not with the vendor.
Compliance is not an optional accessory in ewws. Whoever has to meet the Swiss framework gets it without module bingo. Talk to us for concrete implementation details or a pre-check.
