Invoice scanning for architecture firms in Castel San Pietro: what every SME should know
Between VAT, social contributions and the year-end close, a Swiss SME juggles dozens of deadlines a year. This page focuses on invoice scanning in Castel San Pietro: what the law requires, what can be automated, and when to delegate.
Digitalising invoice scanning: what actually works
Access for the fiduciary, the auditor and employees is set by roles: view, enter, approve, close. Well-set rights protect the data and speed up collaboration.
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 well-structured SME chart of accounts
Concretely, invoice scanning benefits from three tiers: balance-sheet accounts (classes 1-2) kept spotless for the closing, income accounts (classes 3-6) shaped for steering, and closing accounts (class 9) reserved for year-end entries. Each tier has its rhythm and its owner.
For a business in Castel San Pietro, the Sterchi/Käfer structure also eases benchmarking: banks and fiduciaries reason on those standard classes to situate an SME's invoice scanning.
Outsource invoice scanning or keep it in-house?
The scope goes down in writing: who enters data, who approves payments, who answers the tax office, who keeps the originals. Every “we'll see” at the start becomes a December misunderstanding — in Castel San Pietro as elsewhere.
For invoice scanning, the internal-external duo works when both sides see the same file: same entries, same documents, same deadlines. Misunderstandings are born from parallel copies.

QR-bills and friction-free collections
Supplier invoices benefit from the same standard: the QR code is read on receipt, the payment is staged in e-banking with the desired due date, and the expense entry is proposed with the correct VAT. The purchase-payment-posting chain takes three moves.
The winning trio remains: QR-bills for collections, e-banking connected to the accounts for statement imports (camt.053), and automatic matching rules. Exceptions — partial payments, duplicates, missing references — are then handled in minutes, not hours.
Castel San Pietro: what changes, what does not
Sole proprietorship, Sàrl or SA in Castel San Pietro: the AHV contact remains the competent compensation office, and taxes follow the scales of the canton Ticino.
For a business in Castel San Pietro, that means VAT returns identical to anywhere in Switzerland, but a tax return and family allowances governed by the canton Ticino.
Frequently asked questions
How long must records related to invoice scanning be kept?
Ten years from the end of the financial year concerned (art. 958f CO). Electronic retention is permitted if the integrity and readability of the records are guaranteed — a serious digital archive validly replaces paper binders. A business in Castel San Pietro can therefore archive fully digitally.
Effective VAT method or net tax rate: how to choose?
The effective method deducts actual input VAT and files quarterly; the net tax rate method applies a flat industry rate to turnover, semi-annually, with no separate input VAT deduction. The flat rate suits low-cost structures; as investments grow, the effective method usually wins again. The choice rests on the company's own figures, in Castel San Pietro as anywhere.
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 Castel San Pietro as anywhere.
What are the legal obligations for invoice scanning in Switzerland?
The foundation is the Code of Obligations: proper bookkeeping (art. 957a CO), annual accounts (balance sheet, income statement, notes) and 10-year retention of books and records (art. 958f CO). VAT applies from CHF 100,000 of turnover, and social insurance settlements from the first employee. Nothing is different in Castel San Pietro: federal law applies.
