How does AI help with setting up weclapp: chart of accounts, payment providers, tax rules?

The honest formula: the AI reads your system, explains settings, makes suggestions and only writes after preview and approval. A suggestion is text in the chat, not a change in weclapp.

AI-guided accounting setup that creates the chart of accounts, tax rules or payment providers on its own does not exist today. The weclapp help says so itself: before you start, you agree with your tax advisor which method of profit determination and which chart of accounts you use. This does not replace tax advice.

You will find the overview for SaaS providers with weclapp on the page Accounting for SaaS and subscription providers with weclapp.

The Setup Center of wals.pro AI 4 weclapp guides you to the first read access: registration, company profile, plan access, weclapp connection, access profile, AI client and first read access. The step “Install skills” is optional. It sets up the connection, not your accounting. You bring the AI client you connect yourself; its costs depend on its provider.

Whoever sets up the tenant is admin and starts with full access: the AI can suggest changes, and they are only executed after your approval. Invited members start as viewers (read only). For a setup session, we recommend the “read only” access profile for admins or editors.

Your weclapp API token is kept in a secret store and never goes to your AI client. According to the price list, the REST API is available from ERP Services upwards, not in Starter (weclapp list price, as of October 2026). Which license an API user needs, you clarify with weclapp beforehand.

You will find skills after logging in at ai.wals.pro/skills, and more about the product on the page wals.pro AI 4 weclapp.

The AI reaches these areas:

• Accounts and taxes: general ledger accounts, taxes with stored accounts, tax rules.
• Accounting and bank: postings, financial years, open items, bank accounts, bank transactions.
• Reference data and settings: payment methods, payment terms, number ranges.
• System state: background jobs such as DATEV export as well as dunning and payment runs.

Passwords, tokens and access URLs in the settings stay masked. The AI reads bank data such as the IBAN of your bank account and the payment reference of bank transactions, as far as your weclapp API user is allowed to see them; they go to the AI client you connected yourself.

On data flow: the hosted execution layer runs in the EU (Belgium). Content from weclapp is passed through and not stored permanently; log metadata is stored. What the AI reads is processed by your AI provider under your own contract.

With the bundled research skill, the AI is instructed to separate statements by source: schema, reference data, settings or its own conclusion. That is an instruction, not a technical guarantee. The AI does not currently search the weclapp help.

A fictional example. A founder of a B2B tool from Munich has run through the accounting wizard in weclapp ERP Services. Before the appointment she connects the AI in “read only” mode and goes through four points:

1. Chart of accounts: The AI reads the general ledger accounts and taxes with the stored accounts and summarizes which accounts are stored per tax rate (as an example; the result depends on which accounts are stored in your weclapp). Account assignments on the item and rules of the account matrix take precedence and are not included in it. Which chart of accounts was set up is confirmed by the tax advisor.
2. Tax rules: The AI reads the rules and phrases possible gaps as questions: preparation, not an audit, not exhaustive.
3. Payment providers: The AI reads bank accounts and bank transactions and shows the time of the last retrieval, whether automatic synchronization is running and a reported connection error (free text, not every entry is an error).
4. Result: A list of open questions, for example: “For sales to business customers in other EU countries: has the sales rule been switched to the services tax rate?”

None of this changes weclapp. She clarifies the cases with her tax advisor and makes changes herself. This does not replace tax advice.

Today the AI can write to documents and master data, including steps with posting effect such as matching a payment to an open item. Every change first appears as a preview. Your approval is valid once, for 15 minutes, and only for exactly this content; it is bound to it via SHA-256 (digital fingerprint). If a value changes, the approval no longer matches. There is no write path without approval.

Every change in weclapp runs under your weclapp API user. wals.pro AI 4 weclapp logs every call with metadata: who, when, which action, which result. This applies to reading, preview and writing, including rejected calls, and to changes to users, permissions, credentials and connections. The log does not store the content of your records.

The preview shows what changes; whether the posting is correct from an accounting standpoint, you check. Chart of accounts, tax rules, number ranges and payment providers affect every subsequent document; there is no write path for them. The only related exception: the AI can set the tax rate on contract line items after preview and approval. It can assign an existing payment method to documents, but does not change any payment method. This does not replace tax advice.

You clarify these points with your tax advisor, not with the AI:

• Chart of accounts and method of profit determination. In Austria, weclapp supports the Einheitskontenrahmen; you also agree the selection and posting method with your tax advisor, see Accounting for SaaS in Austria.
• Default accounts and UStVA codes. For the advance return via ELSTER, which according to the help weclapp only offers with Germany as the default country, the wizard stores a code for standard taxes; whether every tax rate is assigned correctly, you check yourself. For Austria, you clarify the filing with your tax advisor.
• Tax rules. weclapp provides default rules for goods deliveries. For services to businesses in other EU countries (place of supply and tax liability with the recipient, reverse charge), the weclapp help describes switching the sales rules to the services tax rate. For services to private customers in other EU countries, it describes no rule; you clarify that with your tax advisor.
• Resetting the accounting. According to the weclapp help, the red button deletes the chart of accounts, accounts, all postings in the journal, including locked ones, as well as financial years. Never use it once you have posted productively: postings must not be changed irretrievably and must be retained (Germany: § 146 (4), § 147 AO, ten years; Austria: § 131, § 132 BAO, seven years). Secure an export beforehand and talk to your tax advisor.

Responsibility for your bookkeeping stays with you. The legal basis for VAT is the Value Added Tax Act (UStG) in Germany and the Value Added Tax Act 1994 (UStG 1994) in Austria. This does not replace tax advice.
