Switching accounting software — we move your data for you

The only reason to stay with software that annoys you is the fear of moving. That is exactly what we take off your shoulders: you import clients and services yourself in minutes — and once we receive your invoice and expense exports, we handle the data migration for you. Free of charge, usually within one working day.

01Why switching is easier than you think

Many sole proprietors stay with accounting software that is too complicated or too expensive for years — just because «everything is in there». The good news: you do not have to rebuild your entire history to switch.

For your income and expense statement, only the current financial year matters — previous years are closed and remain as a PDF archive. What you actually need in the new place: your client base, your services, the income and expenses since 1 January and the invoices that are still open. That is the full scope of the move — nothing more.



02What you do yourself — in a few minutes

Two data types you import directly into einzly, without any help from us:

  • Client base: Export it as CSV from your old tool and upload it to einzly. einzly detects the columns automatically and shows you a preview — see the guide Importing clients via CSV.
  • Services and prices: Your service catalogue (items, descriptions, prices) can be imported as an Excel or CSV file — so your first invoice in einzly looks just like before.


03What we take care of for you — free of charge

The part everyone dreads is our job: send us your exports from the old tool — especially all invoices and expenses — and we carry out the data migration for you. Properly booked, not just dumped somewhere:

  • Expenses: We import your current-year expenses with date, amount, category and VAT — your income and expense statement is correct from day one.
  • Paid invoices: We book them as income (one entry per invoice, with invoice number and client) — so revenue, your statement and the VAT return are correct without rebuilding old PDFs.
  • Open invoices: We create them as sent invoices — so you can keep sending reminders seamlessly and no receivable gets lost.
Usually within one working dayIf the exports are complete, your accounting is usually ready in einzly within one working day — with all clients, services, expenses and invoices. The service is free when switching to einzly.


04The checksum guarantee

How do you know everything is correct after the move? Simple: we reconcile the total of imported income and expenses against your reported annual revenue and costs — to the centime. Only when the checksums match is the migration considered complete. You do not have to trust us, you can verify it.

06What happens to the old tool?

Before you cancel: export all invoice PDFs and reports of previous years. In Switzerland, business records must be kept for 10 years — electronically is fine, as explained in Keeping receipts in Switzerland. The old PDFs remain valid; there is no reason to rebuild them in the new system.



07Ready to switch?

Leave us your name and your current tool — we will contact you, tell you exactly which exports we need and take care of the rest. That is how we work in general: software plus real service, as described in Accounting software with service.


Nothing — when switching to einzly, the migration is included. All you need is an einzly account (free 30-day trial).
From any tool that can export CSV or Excel: bexio, Swiss21/AbaNinja, KLARA, Banana, Magic Heidi — or straight from your Excel bookkeeping.
You import clients and services yourself in minutes. Our migration of your invoices and expenses is usually done within one working day if the exports are complete.
No. We book paid invoices as income — you keep the original PDFs from the old tool as your archive. Only open invoices are created as active invoices so the reminder process continues.
