SME chart of accounts for construction companies in Aefligen: rules, deadlines, best practice
Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on SME chart of accounts in Aefligen: what the law requires, what can be automated, and when to delegate.
The Swiss legal frame for SME chart of accounts
Swiss accounting law has been unified in the Code of Obligations since 2013: the same bookkeeping rules (art. 957a CO) and retention rules (art. 958f CO — 10 years for books, vouchers and reports) apply regardless of legal form. SME chart of accounts sits squarely within this frame, including for companies based in Aefligen.
The annual accounts (art. 958 CO) consist of the balance sheet, the income statement and the notes; they must be drawn up within six months of the year-end so the general meeting can approve them. A delay here cascades into the tax return and the final social insurance settlements.
A well-structured SME chart of accounts
A good chart of accounts tells the story of the business: classes 1 and 2 describe what it owns and owes, class 3 what it sells, classes 4 to 6 what it consumes. Private accounts (sole proprietorships) and shareholder current accounts (Sàrl/SA) must stay spotless: they are the first thing examined in a tax audit.
For SME chart of accounts, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.
Digitalising SME chart of accounts: what actually works
Accounting digitalisation always follows the same path: capture documents at the source (photo or PDF upload), let automatic recognition extract supplier, amount, date and VAT, approve the proposed entries, then archive each document linked to its entry. Every step removes a re-keying — and therefore an error source.
Migrate in stages: supplier invoices first (high volume, immediate gain), then receivables with the QR-bill, finally payroll and the closing. At each stage, comparing one month before/after is enough to prove the gain — no theoretical promises needed.

A Swiss SME's accounting calendar
January: salary declaration to the compensation office and salary certificates. End of February, May, August, November: quarterly VAT returns (effective method), each to be filed and paid within 60 days after the quarter ends. Within six months of year-end: approved annual accounts. Then: the tax return under cantonal deadlines, with extensions possible.
The useful reflex: date every obligation the moment it arises. An employee hired means AHV/LPP deadlines created; VAT registration means a filing cycle set; a closing date fixed means backward planning of the close. Well organised, the SME chart of accounts calendar fills itself.
Aefligen: what changes, what does not
Aefligen (postal code 3426, canton Bern) applies the same federal rules as the rest of the country: what changes in Aefligen are the cantonal counterparts — tax administration, compensation office, commercial register.
Federal deadlines do not move in Aefligen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 3426 changes nothing about those rules, only the sender's address.
