Invoice scanning step by step in Bünzen: what every SME should know
Delegate, digitalise or do it all yourself? Around invoice scanning in Bünzen, 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.
Digitalising invoice scanning: what actually works
Artificial intelligence has changed the economics of invoice scanning: automatic invoice reading reaches recognition rates that make manual entry marginal, and posting suggestions learn from corrections. The accountant does not disappear — the job shifts from data entry to control and advice.
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.
Outsource invoice scanning or keep it in-house?
Responsibility stays with the client: the fiduciary executes with care, but the signed accounts bind the company. Understanding what you sign is not optional.
For invoice scanning, a quarterly 30-minute check-in with the fiduciary beats an annual marathon: questions get handled while they are small.
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.
For an SME in Bünzen, receivables are an asset to manage: a weekly ageing balance, graduated reminders and a provision for doubtful cases — invoice scanning provides the numbers, discipline does the rest.

A well-structured SME chart of accounts
A chart of accounts gets documented: one description line per account (what, when, VAT) is enough for two people to post the same way. It is the quality manual of invoice scanning, valid in Bünzen as anywhere.
For invoice scanning, a few well-chosen analytical accounts (by activity, by site) beat a forest of sub-accounts nobody ever reads.
Bünzen: what changes, what does not
Working with a fiduciary from Bünzen no longer depends on geography: the documents of a business in Bünzen are shared online, while the canton Aargau keeps its own deadlines for the tax return.
Federal deadlines do not move in Bünzen: VAT within 60 days, salary declaration in January, 10-year record retention — postal code 5624 changes nothing about those rules, only the sender's address.
Frequently asked questions
Which documents should be prepared for the year-end closing?
Bank and cash statements at the closing date, the inventory of stock and work in progress, final AHV/LPP/accident settlements, contracts signed or amended during the year, invoices straddling two years and the detail of accruals. With an up-to-date document archive, most of it is already there. The list is identical in Bünzen: the CO dictates it, not the commune.
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 Bünzen as anywhere.
What is simplified bookkeeping and who can use it?
Sole proprietorships and partnerships under CHF 500,000 of revenue may limit themselves to recording income, expenses and assets (art. 957 para. 2 CO). Once over the threshold — or upon founding a Sàrl or an SA — full accounts with balance sheet, income statement and notes become mandatory. The CHF 500,000 threshold is assessed the same way in Bünzen.
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 Bünzen can therefore archive fully digitally.
