Introduction

What is WIMM

WIMM is a text-based acconting tool. It joins the ranks of plain text accounting software, such as ledger and co.

WIMM features:

• yaml file format
• support for invoice management
• import of bank statements
• tax (VAT or BTW in Dutch)

Why WIMM

There is a lot of accounting sofware out there, so why wimm? Well, there are many great advantages of of plain text accounting, to name a few of them:

• data is human readable/editable
• plays nicely with version control systems
• new tools/scripts are easy to build

However, I could not find a piece of software that would sufficiently automate my workflow, especially around invoce and tax management. So WIMM was born.

Installation

Wimm is currently in development phase. For this reason there is no pip package available. To install WIMM, clone the repository, then run

pip install -r requirements.txt
pip install -e .

(this will install wimm in development mode)

Documentation

see WIMM documentation

How it works

WIMM works with a database stored in a folder. The folder location is specified with WIMM_PATH envirionment variable.

Data files

Overview of the data files:

balance.yaml - account names that are included in balance calculations, including their starting values

Assets: 0.0
Assets.Bank: 0.0
Ext: 0.0

transactions.yaml - operations for moving money from one account to another

- amount: 1000.0
  date: '2020-01-01'
  description: Customer paid invoice
  from: Ext.Bob
  to: Assets.bank
- amount: 50.0
  labels: office_supplies
  date: '2020-01-02'
  description: bought some pens
  from: Assets.bank
  to: Expenses

invoices.yaml - overview of sent and received invoices.

!!! note invoices have a predefined id that starts with INS or INR in a form INSYY_nnn (INS stands for 'INvoice Sent', INS for 'INvoice Received'). INS and INR prefixes will be recognized by wimm, resulting in suggestions for accounts and tax handling.

- amount: 0
  date: '2000-12-31'
  description: dummy invoice
  documents: invoices/INR.20_000_sample_invoice.pdf
  due_date: null
  id: INR.20_000
  sender: Microsoft
  tax: 0

Data folders

Files added to the database will be copied to corresponding folders. Invoices are stored in the invoices folder. A file location is added as documents field to corresponing data entry in invoices.yaml
