Test first.
Then switch over.
Almost everyone switches from an existing system. That is why every account starts in sandbox mode: real connections, real workflows, test data only. Rechnungskit only reads along and sends nothing, and your current setup keeps running undisturbed. You switch over only when nothing is left open, on a date you set yourself.
Three phases, one moment to switch over
No big bang. Rechnungskit runs read-only alongside your current setup; you check the results and then set the cut-over date.
You set up the account completely: shop and payment connections, number sequences, tax rates, invoice layouts, DATEV export. The important part: the sandbox works with your real orders and payouts from your shop and payment provider. That is the only way to get meaningful documents. Each one is visibly marked as a test document and otherwise looks exactly as it will in production.
The goal of this phase is to find gaps before they cost money: missing master data, untidy product tax rates, special cases with credit notes, layout details. Your tax advisor can pull test exports and look at the result in advance if you like.
You pick a date and time, usually the start of a month, or switch over right away. From that moment on: test data gone, real invoices with GoBD archiving and sending. Only then do you switch off your old setup.
Everything you need for evaluation works from day 0.
Everything that reaches the outside world or is legally binding stays off in test mode.
Testing forever
gets you nowhere.
That's why the sandbox is limited to 90 days. After that it's go-live or account deletion. This prevents a permanent stopgap on your side and dead accounts full of old test data on ours. We remind you in good time, so there are no surprises.
You set the cut-over date.
We handle the rest.
Going live is one click with a date, not a migration. You decide on your own and at any time: no approval from us, no appointment with a contact person and no sign-off from your agency. Until the chosen time everything keeps running as a test; after that the account is live.
The recommended route: run in parallel
During the sandbox phase, Rechnungskit only reads along. It sends nothing, writes nothing back to your old system, and no customer notices anything. So you simply keep your current setup running until you're happy with the result.
