# Post recurring e-conomic bookkeeping vouchers

> Post fixed monthly e-conomic finance vouchers such as rent or subscriptions to a journal, with a check against what is already booked.

Source: https://cotlet.dev/integrations/e-conomic-api-mcp-server/post-recurring-vouchers

Rent, software and leasing repeat every month with the same accounts, and each one is typed into a journal again with the right contra account and VAT code.

Cotlet does it in your own e-conomic account with list\_journal\_entries and create\_finance\_voucher, called by your AI agent, an n8n workflow or a script.

## Can e-conomic do this on its own?

e-conomic supports this through the REST API only (checked 14 Oct 2026). POST /journals/{journal}/vouchers creates vouchers and entries, bulk creation is supported, and a negative amount marks the credit side. There is no MCP server and no scheduling in the API.

## How you do it in e-conomic today

1. Vouchers are entered in a journal, each with an account, a contra account, an amount, a date and a text of up to 250 characters.
2. A VAT code and VAT amount are added when the account needs them.
3. The same entries are made every month, so a repeated voucher or a missed one is the usual mistake.

## How to post recurring e-conomic bookkeeping vouchers

Prompt

```
Post these monthly vouchers to journal 1 in e-conomic with the accounts, amounts and text I gave, and list the voucher numbers.
```

1. 01  
### Look for last month's entry  
The agent reads the journal entries filtered by the same text and amount, so a voucher already posted this month is skipped, not doubled.
2. 02  
### Validate each line  
Each line needs an account, a contra account, an amount and a date. A line with a missing account is listed for you, not guessed.
3. 03  
### Post, one voucher per line  
create\_finance\_voucher runs per line and returns the voucher number. Every call asks for your OK by default, because a voucher changes the books.
4. 04  
### Report what was posted  
The agent returns the voucher numbers with their accounts and amounts, and the lines it skipped as already posted.

### What you get back

Example data

```
Lines in the request: 3
Posted: 2 (voucher 2026-310 rent DKK 4,500.00, voucher 2026-311 software DKK 899.00)
Skipped: 1 (leasing, already posted on 2026-10-01)
```

### Other ways to ask

- Post the same three vouchers on the last day of every month, dated that day.
- Show me what I booked to account 7200 this year without posting anything.
- Post this list of 12 vouchers in one go and stop at the first account that does not exist.

## What e-conomic allows, and what to know first

- A finance voucher entry holds account, contra account, amount, VAT code and VAT amount, and its text is limited to 250 characters.
- POST /journals/{journal}/vouchers supports bulk creation and needs the accounting year and an amount and date for each entry.
- A negative amount marks the opposite side of the booking.
- Journal entries can be listed and filtered by entry type and voucher number.

create\_finance\_voucher asks for your OK by default. To run it weekly without you, switch confirmation off for that tool in your dashboard.
