Registration documents are a starting point for operating a business, not a complete operating system. Before the first invoice, check that your details, records and responsibilities work together. A newly registered autónomo or SL should be able to issue a suitable document, collect payment and explain the transaction afterwards.
Review the registrations received and confirm that the activity and start information reflect the actual business. Keep the filed documents and receipts accessible. If the business is an SL, use the company's details consistently and distinguish its transactions from those of founders who may have incurred preliminary costs personally.
Prepare an invoice process under the applicable rules. Check identifying details, numbering, descriptions and the treatment of IVA and withholding where relevant. Obtain the facts needed for international customers before issuing a document by copying a domestic template. Arrange an appropriate correction process rather than planning to delete an invoice if something changes.
A hypothetical new autónomo receives a customer deposit before completing the first assignment. She records the agreement, payment and relevant invoice documentation, then links the final transaction to the earlier advance. If she waited until final delivery to think about records, the first receipt could become an unexplained bank movement or be counted twice.
Set up the collection of purchases, bank statements and platform reports. Identify who reviews missing documents and when the information reaches the accounting process. Keep assets, financing and owner payments distinguishable from ordinary trading costs. An organised first period prevents the opening months from becoming a permanent reconstruction exercise.
Confirm the ongoing calendar using the obligations applicable to your activity and legal form. Include responsibility for electronic notifications and any later registration updates. If employing staff or using premises, ensure the corresponding requirements have been assessed before those arrangements begin; the general business registration should not be assumed to cover them automatically.
Run a small readiness check using a realistic sale from agreement to invoice, payment and filing of evidence. Resolve any gap before processing many transactions.
