Search Engine Optimization & Technical Site Architecture Auditing
Deliverable Scope Management
Search optimization contracts delineate technical site crawling, server response optimization, mobile usability remediation, canonical indexing architecture, semantic entity clustering, and high-priority backlink audits. When operating in Belgium, clarify statutory deliverable milestones and TVA obligations upfront.
Billing Structure & Fee Models
Bill via comprehensive one-time technical audit fees or monthly performance retainers encompassing specified optimization sprints and monthly SERP ranking deliverables. Standard commercial settlement in Belgium operates under Net 30 terms with statutory late compensation governed by Statutory commercial late payment rate under Law of 2 August 2002 (ECB reference rate + 8 percentage points).
Protective Legal Clauses & IP Rights
State that search rankings are subject to third-party search engine algorithm updates without contractual ranking guarantees, and assign strategy deliverables upon invoice payment. Under Belgium commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs
Deduct enterprise SEO diagnostic tools (Semrush, Ahrefs, Screaming Frog), rank-tracking server APIs, cloud crawler proxies, and digital marketing conference registrations. Maintain all itemized purchase receipts for at least 7 years to satisfy Service Public Fédéral Finances audit mandates.
Timesheet & Milestone Logging Protocol
Maintain baseline crawl audit logs, keyword ranking fluctuation snapshots, page speed diagnostic test sheets, and finalized technical implementation checklists. For registered digital marketers in Belgium, digital PDF records are classified as CONDITIONAL for accounting source verification.
Invoicing Tips & Best Practices for Digital Marketers
Upfront Deposits & Retainers: Require an upfront retainer of 100% for initial diagnostic audits and a 50% deposit before launching new advertising campaign setups. Monthly management retainers must be billed and cleared in advance before work commences.
Common Invoicing Pitfalls:
- Failing to separate marketer management retainers from direct platform ad spend paid to Google or Meta.
- Not defining explicit reporting cadences or limiting impromptu client strategy calls.
- Promising specific ranking or revenue guarantees rather than committing to performance methodologies and deliverables.
- Omitting third-party tool costs (Semrush, Ahrefs, Klaviyo) from campaign development proposals.
Cross-Border Considerations: Cross-border digital marketing consulting exported to overseas business entities qualifies for zero-rated VAT/GST or reverse-charge treatment under destination-based electronic services rules.
