# Automation and custom software

> E-invoicing, receipts, quotes, interfaces and reports at a fixed price - and applications of your own when no standard software fits.

Many businesses work with a mix of spreadsheets, inboxes and programs that each cover only part of the work. That goes well for a long time, until data is kept in three places and invoices still get typed in at night.

I automate such processes. Each automation is small enough to be finished in one to three working days, and it works with the programs you already have.

## Packages at a fixed price

| Package | What runs on its own afterwards | Fixed price, net |
|---|---|---|
| **E-invoicing and receipts** | Receive, check and file e-invoices (XRechnung, ZUGFeRD) and hand them to accounting or your tax adviser; create outgoing invoices in the required format | €690 – 1,490 |
| **Quotes, invoices, documents** | Templates, creation from a form or spreadsheet, sending, follow-up, dunning | €490 – 1,200 |
| **Interfaces and data sync** | Connect shop, accounting, customer management and spreadsheets; no more double entry | €790 – 1,900 |
| **Inquiries and appointments** | Form, automatic reply, calendar, reminder, handover to the customer list | €390 – 900 |
| **Automatic reports** | A weekly or monthly report from existing data: turnover, open items, liquidity | €490 – 1,200 |

Where your price lies within the range is settled after the [automation check](/en/services/consulting-and-planning/), before work starts.

## E-invoicing: the deadlines

Since 2025 all businesses in Germany must be able to receive e-invoices. From 1 January 2027 businesses with more than €800,000 turnover in the previous year must issue e-invoices, from 1 January 2028 all businesses trading with each other. If you switch now, it is done before it gets urgent.

## Applications of your own

When no standard software fits, I build an application that follows the way you work:

- **Internal tools:** order, project or stock management, planning, reports
- **Customer portals:** your customers see orders, documents or appointments and upload things themselves
- **Replacing old systems:** taking over data, setting up processes anew, step by step

Applications of your own I plan in stages, with a fixed price per stage.

## What I have built myself

For my own company I developed a complete accounting system: double-entry bookkeeping to the German SKR04 chart of accounts with locking of entries, a receipt archive with text recognition, bank reconciliation and a DATEV export for the tax adviser. It runs in production every day. I use the same building blocks for client projects.

## Technology

Python and Django, databases as needed, operation in containers on servers in Germany. The source code belongs to your project and is documented.

All prices net, plus VAT.
