Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
5 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by erp-mafia on GitHub. Read the source before you install it.

Installation

Install the Swedish Project Accounting AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/erp-mafia/accounted-skills/tree/main/.claude/skills/swedish-project-accounting
Enable the skill in any chat where you want it available.

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/erp-mafia/accounted-skills.git /tmp/accounted-skills
mkdir -p .claude/skills
cp -r /tmp/accounted-skills/.claude/skills/swedish-project-accounting .claude/skills/swedish-project-accounting

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Swedish Project Accounting in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Swedish Project Accounting on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Swedish Project Accounting is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Swedish Project Accounting (Projektredovisning)

The technical, regulatory and implementation landscape of project accounting in Swedish bookkeeping: for compliance questions and for building software that handles project dimensions.

Projektredovisning tags individual transaction lines with project codes alongside BAS account numbers: same ledger, extra dimension. Projects are never encoded in the account number; they are a separate dimensional layer (objektredovisning), SIE dimension 6. Two things decide most questions: whether the company applies K2 (BFNAR 2016:10) or K3 (BFNAR 2012:1), and whether the contract is fast pris or löpande räkning.

Reference files

Establish the framework (K2 or K3) first, then read the file for the area before answering.

File	When to read
`references/accounts-and-entries.md`	The account summary, the WIP accounts in detail (1470, 1620, 2450, 4970), journal entries per scenario, moms timing, fördelningsnycklar, closing entries
`references/k2-k3-revenue-recognition.md`	When project accounting is required, the full decision tree, K3 Chapter 23, K2 Chapter 6, befarade förluster, noter, gross reporting, K2 vs K3
`references/sie4-project-dimensions.md`	Projekt vs kostnadsställe, #DIM/#OBJEKT/#TRANS encoding, project-tagged import/export, Fortnox/Visma/Bokio mapping
`references/tax-and-grants.md`	Tax on pågående arbeten, materiellt samband, löpande räkning divergence, forskningsavdrag, aktivering av utvecklingsutgifter, omvänd skattskyldighet, EU grants
`references/implementation-patterns.md`	Data models, project lifecycle, WIP calculation, overhead allocation, profitability reporting, time tracking, common error patterns

The revenue recognition decision

Contract	Framework	Method
Löpande räkning	K2 and K3	Recognize revenue as work is performed. Tax may diverge from accounting (IL 17:26; scope per IL 17:23)
Fast pris	K3, koncernredovisning	Successiv vinstavräkning MANDATORY: revenue = total contract × färdigställandegrad at each balance date. Outcome not reliably estimable (all four conditions met?): revenue = costs incurred, zero profit
Fast pris	K3, juridisk person	Successiv vinstavräkning OR färdigställandemetoden (punkt 23.31, only industries in 17 kap. 23 § IL)
Fast pris	K2	Method choice 6.15: huvudregeln (completion %, 6.16–6.21) or alternativregeln (6.22–6.25, recognize when "väsentligen fullgjort"; Srf U 15: assessed from customer acceptance perspective)

Befarad förlust overrides the method. K3 punkt 23.24 (successiv vinstavräkning; punkt 23.32 when a juridisk person uses färdigställandemetoden) and K2 punkt 6.19 (huvudregeln) / 6.23 (alternativregeln): if total estimated costs exceed total contract revenue, the expected loss must be recognized as a cost IMMEDIATELY, regardless of completion percentage. The engine must flag projects where cumulative actual + estimated remaining costs exceed contract revenue.

Never guess these

Situation	Why	What to do
Moms on a WIP entry	1620 is pure periodisering with NO moms; moms behind 2450 is reported at invoicing	Track moms reporting independently from revenue recognition, per project
K2 or K3	It decides the available methods, and K2 punkt 10.4 forbids capitalizing egenupparbetade immateriella tillgångar	Ask, or check the last årsredovisning
Färdigställandegrad	Revenue follows directly from it, in both directions	Ask for the cost-to-complete estimate; flag completion % diverging >20% from time-elapsed or budget-consumed
Netting two projects' balances	Gross reporting per project is required (Srf U 14, ÅRL kvittningsförbud)	Show 1620 and 2450 per project, never net them
Closing a project with residual 1620/2450/1470	Residuals and missing garantiavsättningar are common audit findings	Enforce a zero-balance check before CLOSED
Whether project tags survive an export	Bokio tags do not export as SIE dimensions	Check the source system's dimension model first

Frequently asked questions

What does the Swedish Project Accounting AI skill do?

Why use Swedish Project Accounting on TypingMind?

Because you install it once and use it with any model. Swedish Project Accounting is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Swedish Project Accounting in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/erp-mafia/accounted-skills/tree/main/.claude/skills/swedish-project-accounting. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Swedish Project Accounting?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Swedish Project Accounting?

As many as you like. As long as a model supports skills, you can use Swedish Project Accounting with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Swedish Project Accounting AI skill free?

Yes. It is published on GitHub by erp-mafia under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
