Prepare Billomat quotations with AI
WZ-IT makes existing quotations and invoices usable, separates them from current product data and designs the handover as an editable Billomat draft. API access, required fields and follow-on documents are assessed in advance.

Integration status
Integration path after API assessment
Billomat documents REST resources for quotations and quotation line items. Line items are handled in DRAFT state. WZ-IT assesses the concrete account, data and approval scope before implementation.
From input to editable draft
The integration connects existing data to a controlled handover and approval path.
- 1
Identify case and customer
The new request is associated with existing customer and project context.
- 2
Classify historic line items
Earlier documents show typical service combinations while current data determines price and scope.
- 3
Build the DRAFT quotation
Header and line-item data are prepared for an editable quotation state.
- 4
Separate approval and follow-on process
Quotation state, acceptance and any invoice derivation remain distinct process steps.
What is assessed through the official API
Use the quotation resource
Customer context, quotation data and status are mapped to the official quotation resource.
Maintain positions in DRAFT
Recurring line items can be prepared as an editable draft and then reviewed by the responsible person.
Model invoice derivation separately
An invoice from a quotation requires a confirmed follow-on process and is not generated solely from historic invoices.
Explicit system boundary
State changes and follow-on documents are not treated as incidental automation. They require explicit triggers, roles and a traceable delivery basis.
Assessment, pilot and ongoing operations
For this provider, edition, API access and the document workflow are confirmed first. The integration pilot is scoped definitively only after that assessment; ongoing operations remain a separate service.
Optional starting point
Data and process assessment
from €1,490
excluding VAT, one-time
For projects where the document estate, target system or responsibilities first need to be defined reliably.
- Assess sample documents and data sources
- Verify the target system, interface and approval path
- Define the pilot scope and technical risks
Implementation
Integration pilot
from €4,990
excluding VAT, one-time
One clearly scoped quotation type is implemented from the agreed sources through to an editable draft in the target system.
- Structure the document estate and catalogue candidates
- Connect the current pricing and service source
- Test draft logic, clarification and handover
Ongoing operations
Managed quotation assistant
scoped individually
monthly managed service
For production workflows whose platform, integrations and data sources require technical monitoring and maintenance.
- Monitoring and technical fault analysis
- Planned updates for the platform and integration
- Technical maintenance of agreed data sources and field mappings
Document volume, additional quotation types, further companies, individual data cleansing, extra integrations and specific operational requirements are itemised separately in the proposal.
All prices are net and exclude statutory VAT. The offers are addressed to businesses.
Integration in four steps
- 1
Assess plan, API and data model
Access, available resources, contacts, document status and required fields are verified technically.
- 2
Connect sources and rules
Historic documents, current product data, prices, approved wording and approval rules receive distinct roles.
- 3
Test the draft path
One scoped quotation type is tested with sample data through to an editable document in the target system.
- 4
Accept and extend
After subject-matter acceptance, more quotation types, users, data sources and managed operations can follow.
Other integration paths
Other accounting systems or defined export paths can also be included after an interface and edition assessment.
Request integration
Assess the quotation process and target system
Briefly describe the historic document estate, current product data and present workflow. Credentials are not needed for the initial assessment.
Frequently asked questions about the integration
Answers to the most important questions
Billomat documents quotations and quotation line items through its REST API. Quotation line items are created or edited while the quotation is in DRAFT state.
Yes, where the necessary data is available through the API, an export or provided documents. Historic content remains a reference and is not a current pricing source.
Billomat documents relationships between quotations and invoices. WZ-IT only includes that path with a confirmed order, clear quantities and a governed approval step.
No. The API path is technically suitable but is implemented individually based on account, API access, document types, data sources and approval process.
Implementation starts from €4,990 excluding VAT. The final price depends on the document estate, API access, required quotation and line-item data and the governed DRAFT and approval workflow.
Software projects with reliable outcomes
Proof for modernization, API extension, architecture, deployment and ongoing operations.
“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”

“With Timo and Robin, you're not only on the safe side technically - you also get the best human support!

The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated)”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
