The contract runs a year – the billing runs every month
A Rahmenvertrag is won when it is signed. It is earned across hundreds of individual Abrufe, every one of which has to be evidenced.
Call-off and evidence
The Abruf comes by phone – the evidence has to be in writing
Between the authority’s call and a checked invoice lie several handovers. Each one is a place where a document goes missing or a quantity is copied wrong.
A call, a note, a Zettel.
| Item | Description | Quantity |
|---|---|---|
| 01.01.0020 | Break up asphalt, up to 12 cm | 18.40 m² |
| 01.03.0060 | Supply and lay frost protection layer | 9.20 m³ |

At an audit this is exactly the link that gets asked about: which item belongs to which call-off, and which call-off to which contract.
The flow
From the phone call to the monthly invoice
1Record the Abruf
Date, location, work – and which contract it belongs to.
2Zettel on site
The crew measures and writes as before; the paper does not change.
3Collect at month end
Abrufe under the same contract come together in one billing run.
4Issue one invoice
A hundred small jobs, one XRechnung the authority can check.
In contract work
What Excel cannot hold together
- Which Abruf belongs to which contract – nobody remembers at month end
- The remaining quantity is unknown until the contract runs out
- The same job billed twice, noticed first by the client
- A price adjustment cannot be applied retrospectively
- When an audit comes, somebody hunts for the Zettel behind a line
Common questions
Questions from contract work
Can we run several Rahmenverträge at once?
Yes. Each contract carries its own item list, its own Leitweg-ID and its own remaining quantity; the contract is chosen when the Abruf is recorded.
How do we see the remaining quantity?
In the contract view, per item: contracted, called off, remaining. Not an estimate – the sum of the Abrufe recorded.
Can we apply a price adjustment (Preisgleitung)?
If the contract provides for it, yes: the new unit price is entered with its effective date and applies to Abrufe after it. Correcting the past is done by Storno and a credit note – invoices are never overwritten.
Walk through your own contract
Bring a running Rahmenvertrag and a few Zettel from last month. You will see how a hundred small jobs become one invoice that survives checking.
