The area is not used yet. Nothing is built, nothing is numbered.
laeuft/All features/Switching
Switch area by area, without a cutover day.
ERP switches rarely fail on features. They fail on the day everything moves at once. laeuft works next to your current system first, compares every number with yours and takes over one area at a time, only when you say so.
Areas
Shadow builds every effect and compares it. Nothing leaves laeuft until an area is live.

One switch per area
Every area is Off, Shadow or Live.
Every area with an effect outside laeuft (documents and mails to customers, uploads to channels, stock and price feeds, the DATEV handover, reminders) has its own switch. It starts at Off.

Shadow
laeuft builds every effect in full (the document, the file, the payload), compares it with your current system and sends nothing.
OffShadowLive
laeuft acts, your old system stops here.
Real numbers, real sending
Only with your explicit go
Live
laeuft takes over: real numbers, real sending. Only with your explicit go, area by area.
How it works
From parallel to live, with proof before every step.

Run in shadow
For every order laeuft computes what it would do: the invoice, the price, the booking. Shadow documents get their own number series and never use a real number.

Compare every number
Each result is set against your current system: identical, deviating, or not comparable yet. In September 217 of 220 invoices were identical to the cent.

Explain the rest
Every deviation shows both values and the reason, often a rounding rule or a tax case the old system treats differently. You fix a rule or accept the difference.

Go live, one area
When the numbers match, you switch the area to live. From then on laeuft sends, and your current system stops doing that job.

Details
What is compared, exactly.
- Orders
- Read directly from Amazon, eBay, Kaufland, Shopify and the Mirakl marketplaces and matched with the same order in your current system, strictly read only.
- Invoices and credit notes
- laeuft calculates each document itself, per VAT rate, and compares totals to the cent: identical, deviating, or not comparable yet.
- Prices
- Your price rules become a versioned rule set in laeuft; every calculated price is compared with your current price logic. 50 of 50 were identical.
- Bookings
- Per month and per document number: matches, deviates with reason, only in laeuft, only in your current export.
- Shadow numbers
- Shadow and trial documents use their own series. Going live starts the real series at the first number of the year, without gaps or burnt numbers.
- Nothing sent in shadow
- Documents, mails, channel uploads, stock and price feeds, DATEV and reminders are built in full but stay inside laeuft.
- Live needs your go
- Every switch defaults to Off. Turning an area live is an explicit decision per area, never a side effect.
- A clean month for the books
- Bookkeeping goes live after at least one full month without an unexplained deviation.
Questions
Before you switch.
Does my team have to work in two systems?+
No. In shadow, laeuft only reads and computes; your team keeps working as before. Double work only starts where you choose to move a task into laeuft.
How long does shadow mode take?+
As long as the numbers need. For invoices and prices that can be days; bookkeeping needs at least one full clean month.
What if the numbers don’t match?+
Then the area stays in shadow. Every deviation shows both values and its reason, so you can fix a rule or decide that the old system was wrong.
Can customers notice the shadow mode?+
No. Nothing leaves laeuft in shadow: no mail, no document, no upload, no feed.
Do we need a big migration project?+
No. The catalogue is taken over once, orders come straight from the channels, and every further step is one switch per area.
