Swedish cash register (kassaregister), staff ledger (personalliggare) and the bookkeeping of daily takings.

Use it in TypingMind
Enable Swedish Cash Register 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.
SkillsLoad skill"swedish-cash-register"
Gemini 3.5 Pro
The model loads Swedish Cash Register 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 Cash Register 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 Cash Registers and Cash Sales
Two separate duties meet at the till: the regulatory one (does this business need a certified kassaregister, and what must it record) and the bookkeeping one (how the day's takings become a verifikation and reach the ledger). This skill covers both.
Account numbers follow BAS 2026.
How to use this skill
File
When to read
references/kassaregister.md
Whether a register is required and what the rules demand: SFL 39 kap, exemptions, the 4 PBB threshold, anmälan, tillverkardeklaration, kontrollenhet vs kontrollsystem, the 2027 XML journalminne deadline, kassakvitto contents, personalliggare, kontrollbesök and kontrollavgift
references/cash-bookkeeping.md
Booking the takings: Z-dagrapport as verifikation, VAT split per rate, the split between kontant, kort and Swish, växelkassa, kassadifferens, bank deposits, dricks, personalmåltider, presentkort, kontantmetoden, reconciliation
Start here
Does the business sell against cash or card to consumers? If yes, the kassaregister rules apply unless an exemption fits. Sales only on invoice against payment afterwards are outside them.
Check the exemptions properly. Turnover at or below 4 prisbasbelopp (236 800 kr for 2026) is the common one. Note two traps: torg- och marknadshandel is not exempt, and lacking a permanent establishment in Sweden does not exempt a business either.
If a register is required, it must be reported to Skatteverket, carry a tillverkardeklaration and be connected to a kontrollenhet or kontrollsystem. From 1 January 2027 it must meet SKVFS 2021:17, and a register with a journalminne must be able to produce its records as XML.
Then book the day. The Z-dagrapport is the verifikation for the day's sales. Cash sales must be recorded by the next working day. Split by VAT rate, and keep the payment split so the bank and card payouts can be reconciled.
Two things that are easy to get wrong
Food is at 6 % until the end of 2027, but serving stays at 12 %. A café selling both take-away and eat-in has two rates in the same Z-report. See swedish-vat for the boundary.
Tips can be the company's income or pure pass-through, and the answer decides whether skatteavdrag and arbetsgivaravgifter apply. See references/cash-bookkeeping.md and swedish-payroll.
Never guess these

Why
What to do
Turnover close to 4 PBB
The duty appears when the threshold is passed
Ask for expected turnover from cash and card sales
Swish at the point of sale
The statute names kontant and kontokort; Skatteverket's published guidance is thinner than it looks
Flag the uncertainty rather than asserting an exemption
Recurring kassadifferens
Small differences are normal; a pattern is not
Ask for the Z-reports and count routine before booking
Tips paid by card
The employer's role in distributing them decides the payroll treatment
Ask how the money reaches the staff
An unreported byggarbetsplats
The kontrollavgift is charged per occasion
Ask whether the site was reported before advising

Why use Swedish Cash Register on TypingMind?
Because you install it once and use it with any model. Swedish Cash Register 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 Cash Register in TypingMind?
Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/erp-mafia/accounted-skills/tree/main/.claude/skills/swedish-cash-register. 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 Cash Register?
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 Cash Register?
As many as you like. As long as a model supports skills, you can use Swedish Cash Register with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.
Is the Swedish Cash Register 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.
