Chapter 1

How do you organise administration in an SME?

Start with business workflows

List your client, supplier, workforce and accounting workflows. For each, describe the trigger, required documents, approvals and expected result. Follow a few actual files to distinguish the planned process from daily practice.

Identify bottlenecks

Identify missing documents, duplicate entries, approvals without deadlines and information held by one person. For each difficulty, record its frequency, effects and the circumstances in which it occurs.

Define a common foundation

Create a list of open files, responsibilities and deadlines. Define understandable statuses: to complete, to check, to approve, submitted or closed. A status should correspond to a specific action or condition.

Roll out gradually

Choose a priority workflow rather than changing all administration at once. Test rules on routine and exceptional cases, collect feedback and adjust. Tool complexity should remain proportionate to the need.

Chapter 2

How do you allocate administrative responsibilities?

Describe the tasks

Avoid broad labels such as “manage invoices”. Break the work down into receipt, checking, approval, submission and follow-up. Specify the information required at each stage.

Assign a role to each stage

Define who does the work, who decides and who receives information. Adapt controls to the risks and resources. A useful allocation also indicates the expected deadline and cases requiring a decision.

Plan backup cover

Identify a backup for critical tasks and check that they have authorised access and the necessary instructions. Cover should not depend on informal password sharing.

Check against practical cases

Test responsibilities with an incomplete order, a supplier disagreement or an urgent file. Define an escalation procedure. Review responsibilities when activities or people change.

Chapter 3

How do you organise business documents?

Define a filing structure

Choose a structure related to the work: client, supplier, project or administrative category. Specify the authoritative location to prevent multiple competing versions of the same file.

Name and identify versions

Define a short naming convention containing the elements needed for retrieval. Distinguish drafts from approved versions. Rules should be applicable consistently by different people.

Organise access

Personnel files and other personal data require particular care. The Belgian Data Protection Authority’s SME guide recommends access based on a need-to-know policy. Check permissions when people join, change roles or leave.

Define archiving and retention

Separate active and closed files. Define retention rules by category after checking the relevant obligations. This guide does not propose one retention period for every document. Organised archiving does not replace a tested backup.

Chapter 4

How do you make the quotation–order–invoice workflow more reliable?

Retain the agreed reference

Identify the accepted offer, agreed terms and any changes. Each version must be traceable to the relevant file. Scope changes must be addressed before subsequent documents are produced.

Prepare execution

Check that the necessary information is available: contact, service, schedule and operational details. Specify who confirms readiness and who handles missing information.

Reconcile the documents

Before invoicing, reconcile order details and evidence of delivery as appropriate. Define how discrepancies and disputes are handled. Tax rules and applicable invoice details should be checked with the relevant professionals.

Track submission and payment

Distinguish invoices that are prepared, sent, received and paid. In Belgium, consult the official e-invoicing portal to check the scope and arrangements for structured electronic invoicing. This guide describes workflow organisation, not all invoicing rules.

Chapter 5

How do you maintain administrative continuity during an absence?

Identify dependencies

List deadlines and operations that cannot wait. Identify information or practices held by one person and approvals dependent on a single contact.

Document the essentials

Prepare short instructions covering the objective, steps, required documents, contact, deadline and escalation cases. Maintain a list of open files and their next action. Update a procedure when it no longer reflects the work.

Prepare access arrangements

Organise authorised individual access rather than sharing passwords. Check the backup person’s permissions and recovery mechanisms. Continuity must remain compatible with file confidentiality.

Test the handover

Have the backup person process a file before a planned absence. Identify missing information and adjust. On return, hand over completed actions, incidents and outstanding decisions.

Practical context and sources

The methods presented are Ethadex working guidelines. Access to personal data and retention rules must reflect the processing involved and applicable obligations. The invoicing workflow must take the requirements applicable to the business into account.
