Accounting that happens on the phone .
Receipt photographed, call made, invoice created — DATEV gets everything nightly in the receipt-transfer format. Your tax adviser pulls the data daily from DATEV Unternehmen online. Double entry eliminated. Typing hours eliminated.
Why another accounting module when DATEV exists?
DATEV is tax-advisor software, not entrepreneur software. voiceOne solves the typing.
Photograph the receipt = done
Photo of the delivery note, fuel receipt, invoice — the AI reads it, pre-assigns the accounts, writes it to DATEV. Your tax adviser gets the receipt digitally plus a posting suggestion.
Create a receipt during the call
Time tracking on the phone, invoice on the phone, cash posting on the phone. Every business transaction goes straight into OPOS accounting.
Sync, not export
Classic tools export a file once a month. voiceOne syncs continuously — your tax adviser sees yesterday's receipt this morning.
GoBD with no ifs and buts
Hash chaining, audit log, procedural documentation. In a tax audit we put the history of every posting on the table. Included.
What voiceOne can do
A complete accounting pipeline — receipt, booking, cash register, accounts, ELSTER.
