Accounts payable for engineering firms in Fehren: rules, deadlines, best practice

Delegate, digitalise or do it all yourself? Around accounts payable in Fehren, every SME draws its own line. The reference points below — federal law, cantonal practice and lessons from the field — help you place the cursor well.

The Swiss legal frame for accounts payable

Whether a business sits in Fehren or elsewhere in Switzerland, the same federal law applies — one of the strengths of the Swiss system for accounts payable. Cantonal differences concentrate on taxation (rates, filing deadlines); bookkeeping itself follows art. 957 ff. CO everywhere.

Art. 957a CO requires complete, truthful and systematic recording of transactions, each entry backed by a supporting document. For accounts payable, that means in practice: no movement without a receipt, and an audit trail that can be reconstructed at any time — including during a VAT or AHV inspection.

Digitalising accounts payable: what actually works

Security is part of digitalisation: named access, tested backups, encryption of sensitive data. A digital accounting file is protected like a safe — because it is one.

The winning pair for accounts payable: a single inbox (e-mail, scan, photo) and one simple rule — no document sits more than a few days without a proposed entry.

Outsource accounts payable or keep it in-house?

A fiduciary's cost depends first on the quality of the data received: digitised, filed, reconciled documents are processed fast; a box of loose receipts is billed by the hour. Improving the internal preparation of accounts payable lowers fees more surely than any negotiation.

For accounts payable, the internal-external duo works when both sides see the same file: same entries, same documents, same deadlines. Misunderstandings are born from parallel copies.

A Swiss SME's accounting calendar

Three families of deadlines shape the year: federal (VAT within 60 days, salary declaration in January), cantonal (tax return, extensions depending on the canton, including in Fehren) and internal (closing, general meeting within six months). Mixing them up is the leading cause of delays.

For accounts payable, two dates lock themselves in every year: the January salary declaration and the general meeting within six months — everything else is planned around them.

Fehren: what changes, what does not

Working with a fiduciary from Fehren no longer depends on geography: the documents of a business in Fehren are shared online, while the canton Solothurn keeps its own deadlines for the tax return.

For a business in Fehren, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Solothurn.

Frequently asked questions

What is the difference between a limited and an ordinary audit?

The ordinary audit applies to companies exceeding, for two consecutive years, two of three thresholds: CHF 20 million balance sheet total, CHF 40 million revenue, 250 full-time positions. Others fall under the limited audit, and those with no more than ten full-time positions on annual average can opt out with all shareholders' consent. These federal thresholds do not depend on the registered seat — in Fehren as anywhere.

Which social contributions does a Swiss employer pay?

AHV/IV/APG: 5.3% employer share (the same is withheld from the employee); unemployment insurance: 1.1% each up to CHF 148,200 a year; occupational pension (LPP) by age and plan (employer at least 50%); occupational accident insurance paid by the employer; family allowances by canton. For an employer in Fehren, family allowances follow the canton's rates.

Do you need a fiduciary for accounts payable, or can you do it yourself?

Both are defensible. Below CHF 500,000 of revenue, a sole proprietorship may keep simplified accounts itself. As soon as payroll, VAT and a closing with tax stakes are involved, professional support prevents mistakes that cost more than the fees. With a shared platform, the fiduciary does not even need to be in Fehren.

When must a business register for VAT?

As soon as its worldwide annual turnover reaches CHF 100,000 (CHF 250,000 for non-profit sports or cultural associations). Below that, voluntary registration remains possible and often makes sense to reclaim input VAT on investments. The threshold is federal: it applies in Fehren as everywhere in Switzerland.
