From the tools finance already uses to structured e-invoices
Keep invoices flowing from familiar accounting software while adding a controlled path to EN 16931-oriented invoice packages.
EINvoicer is designed around export and API intake from common SMB and mid-market accounting systems, then maps invoice fields into repeatable e-invoice packages with reviewable exceptions before files leave the finance team.
- Sage, QuickBooks, Xero
- Pennylane, Cegid, EBP
- DATEV, Lexware, sevDesk
- Odoo and SAP Business One
Common tools
Export and API intake
Plan conversion from CSV, XLSX, XML, API, and PDF-adjacent exports used by everyday accounting systems.
Exceptions
Issues before sending
Flag missing buyer references, tax inconsistencies, address gaps, and line-item problems before delivery.
Rules
Reusable mapping logic
Apply consistent field rules across accounting tools, recurring customers, entities, and invoice templates.
Product detail
Practical conversion, visible controls
Start from the accounting stack you already have
EINvoicer should not force a finance migration just to meet invoice format expectations. It can start from exports, API feeds, or structured reports produced by the systems already in place.
Desktop and SMB tools
Support conversion planning for tools such as Sage 50, QuickBooks, Xero, FreshBooks, Zoho Books, and similar export-driven workflows.
France and EU tools
Prepare mappings for Pennylane, Cegid, EBP, Odoo, and local ERP exports where French or European formats are part of the rollout.
Germany and ERP tools
Work from DATEV, Lexware, sevDesk, SAP Business One, and other ERP exports where ZUGFeRD or XRechnung profiles may be needed.
Make the cross-tool field map explicit
The useful work is in the details that vary between tools: customer records, VAT identifiers, payment terms, delivery references, discounts, rounding, and line-level tax data.
Customer records
Normalize names, addresses, VAT IDs, buyer references, and routing identifiers before invoice creation.
Line items
Preserve descriptions, quantities, units, prices, discounts, and tax categories with clear rounding rules.
Payment fields
Carry due dates, payment terms, bank details, remittance references, and payment means into the structured layer.
Workflow
Conversion path across accounting tools
The process is intentionally plain: collect representative exports, make the transformation visible, and keep a review trail across each source system.
01
Collect sources
Start with representative exports, API payloads, invoice PDFs, and sample files from the tools finance uses today.
02
Map fields
Define structured invoice mappings and exception rules per accounting tool with finance, not just engineering.
03
Verify packages
Compare generated files against source invoices and validate the structured invoice data before rollout.

FAQ
Questions before the first invoice batch
Do we need a perfect export first?
No. A representative sample is enough to start the mapping review. The first implementation should identify which fields are reliable and which need enrichment.
Can different accounting tools and invoice templates be handled?
Yes, but they should be grouped and tested deliberately. Each source system and invoice family may need its own mapping assumptions and exception checks.
Can this run before the final invoice rules are locked?
Yes. The safest approach is to start with mapping, samples, and validation evidence early, then adjust the profiles as platform and national requirements settle.
