A structured switch from Bexio, Topal, Abacus, Sage or Excel to ewws.

Migration is not a topic for improvisation. You follow a clear path with data audit, mapping, parallel operation, deadline and cutover. Chart of accounts, open items, master data, documents and the payroll master come along.

Six ways to ewws

Every source system has its own migration path.

A switch from Bexio runs differently than from Topal or Abacus. The data structure, the interfaces and the historically grown conventions differ per system. ewws knows six standard paths and brings mapping templates per source system.

Cloud SME software

Switch from Bexio

Bexio is the most common source among Swiss micro-enterprises. The switch fits especially when data should no longer sit in a single external cloud, or when the module toolkit hits limits (several tenants, payroll run, inventory, project controlling). Data export from Bexio runs via CSV and API, ewws imports with prepared mapping templates.

What comes along: Chart of accounts, customers, suppliers, articles, open items, invoices, payroll master, VAT rates

Recommended parallel operation: 3 to 4 weeks, ideally at the quarter change

Fiduciary-focused

Switch from Topal

Topal has a strong fiduciary profile and many mandates. The switch is common when fiduciary offices look for a modern Mac-native platform with the same or better fiduciary functionality, or when several tenants are to be consolidated. ewws takes over per tenant and carries the fiduciary hierarchy on cleanly.

What comes along: Chart of accounts per tenant, posting stock, open items, master data, payroll master, VAT profiles, fiduciary roles

Recommended parallel operation: 4 to 6 weeks, staggered per tenant

SME to mid-market

Switch from Abacus

Abacus covers a broad feature set and is widespread in the Swiss mid-market. The switch fits customers who look for a more economical license model or Mac-native operation. Abacus exports via structured XML and SQL views. ewws imports via the migration cockpit, without data loss in accounting, inventory and payroll.

What comes along: Chart of accounts, postings with history, open items, master data, articles with stock, assets, payroll master with wage types

Recommended parallel operation: 4 to 8 weeks, depending on volume and number of tenants

Classic accounting

Switch from Sage

Sage 50 and Sage 200 are widespread in German-speaking Switzerland, especially in accounting and classic order management. The switch fits customers who additionally want inventory, projects or a payroll run integrated. Sage exports via clear standard formats. ewws offers a mapping per Sage version.

What comes along: Chart of accounts, postings, open items, master data, articles with stock, orders, invoices

Recommended parallel operation: 3 to 5 weeks, optimally before the financial year-end

From Excel and isolated solutions

Switch from Excel and isolated solutions

Many Swiss SMEs still keep their master data and documents in Excel or in several small isolated solutions. The switch to ewws is the biggest step, but also the biggest gain. ewws provides bulk import templates for CSV and Excel, with validation against Swiss standards such as postal code, IBAN and VAT number.

What comes along: Master data from Excel, manual postings via import template, open items list, simple payroll masters

Recommended parallel operation: 2 to 3 weeks, with a clear deadline

Micro-enterprises and associations

Switch from Banana accounting

Banana is widespread in Switzerland among associations, sole proprietorships and the smallest fiduciary mandates. The switch fits when a micro-mandate becomes an SME or when Mac-native operation, inventory, payroll run and QR-bill are wanted in one product. Banana exports via Swiss standard formats (AC2, CSV). ewws takes over accounts, postings, open items and VAT profiles per tenant.

What comes along: Chart of accounts, posting stock with history, open items, master data, VAT profiles, simple payroll masters

Recommended parallel operation: 2 to 3 weeks, well suited to the start of the year

Migration process

Six steps from the source system to productive operation in ewws.

The process is the same, regardless of which source system. Fiduciaries can run steps 1 to 3 for several tenants in parallel.

Step 1

Data audit and inventory

Which data volumes are in the source system, which modules are active, which special cases (VAT special rules, wage types, foreign currencies) exist. The result is a written list of what comes along and what is deliberately left out.

Step 2

Mapping and chart of accounts

Chart of accounts, cost centers, VAT profiles, article groups and employee categories are mapped from the source system to the ewws model. There is a standard template per source system that we adapt individually.

Step 3

First import and test run

A complete import on a test tenant in ewws. Spot checks against the source system, account balances, open items and VAT totals are reconciled. Differences are documented and resolved.

Step 4

Parallel operation

Both systems are run in parallel for a defined period. New documents are captured in both systems, banking only in one. The goal is certainty that ewws maps reality cleanly before the cutover happens.

Step 5

Deadline and closing balance

A deadline is set, closing balances from the source system are transferred into ewws, the opening balance is posted. The source system is set to read-only and is kept for the ten-year GeBüV retention obligation.

Step 6

Cutover and training

ewws goes productive, users are trained, the source system stays as an archive. Fiduciary customers are connected to the fiduciary portal in the same session, banking runs only via ewws from the deadline.

What is taken over

Six data families that come along cleanly.

Every data family has its own import path with validation rules. This way an import does not become a data ruin, but a reproducible operation.

Chart of accounts and postings

The Swiss SME chart of accounts or your own chart of accounts is taken over, supplemented with the ewws mandatory fields. Existing postings come either as history or as an opening balance, depending on the chosen deadline.

Open items

Receivables and payables with amount, due date, reference and dunning level. The dunning levels are mapped to the ewws dunning logic, so that the first run after cutover calculates correctly.

Master data

Customers, suppliers and articles with all relevant fields such as address, postal code, tax rate, IBAN, payment term and storage location. Duplicate records from the source system are detected in the pre-audit and consolidated.

Documents and files

Quotes, orders, invoices and goods receipts can be taken over either fully as history or from the deadline. Original PDFs are filed in the GeBüV document archive and secured with a hash chain.

Payroll master and HR

Employees, wage types, social insurance assignments, BVG and withholding tax tariffs. Payroll prior years can be taken over as non-posting history, the first productive payroll run follows directly after cutover.

Assets and inventory

An asset master with a depreciation schedule and residual book value, stock with value, serial numbers and batches. For tenants with a stock-taking obligation, the stock-take is run in ewws directly after the deadline.

Migration is routine, not a risk. When the plan is in place.

We accompany the switch personally, with clear steps and without live-operation improvisation. If you want to switch from Bexio, Topal, Abacus, Sage or Excel, send us the source system and the number of tenants, then we discuss the path.
