Consultant: Moving From Day Rates to Recurring Revenue

An independent consultant in Europe typically bills €400–800 per day depending on speciality. On paper, that's comfortable. In reality, day rates hide a structural problem: between engagements, the meter drops to zero.

Concretely, a consultant billing €600/day who works 180 days per year generates €108,000 in revenue. But those 180 days aren't evenly distributed: some months are 100% capacity, others 20%. This irregularity makes any financial planning precarious.

The trend is global: according to the Zuora Subscription Economy Index, subscription businesses grew 3.4x faster than the S&P 500 over 12 years. In France alone, the number of freelancers exceeded 1.2 million in 2024.

Recurring revenue doesn't replace engagements. It creates a foundation: even in slow months, a revenue base runs automatically. For the full picture, see our complete guide for independents.

The monthly retainer

Your client reserves a volume of hours or days each month, billed automatically. Example: 2 consulting days per month for €1,000. The client gets priority access; you get guaranteed revenue.

This model works particularly well for strategic consulting, IT consulting, and HR consulting — domains where needs are continuous.

The advisory subscription

You offer access to your expertise within a defined scope: email responses within 24h, a monthly phone call, and access to a document library. Typical pricing: €500–1,500/month.

The advantage: the client pays for availability and expertise, not time spent. You decouple your revenue from your hours.

The productised offering

You transform a repetitive service into a fixed-price product. Examples:

• Monthly SEO audit: €350/month
• Updated financial dashboard each month: €200/month
• Weekly competitive intelligence: €150/month

This model is ideal for consultants who already deliver recurring services to their clients without formalising them as subscriptions.

1. Identify your recurring service. Look at your last 12 months: which client contacted you regularly? For what type of request? That’s your first retainer candidate.

2. Formalise the offer. Define what’s included (number of days/hours, response times, deliverables) and what’s not. Clarity of scope prevents scope creep.

3. Set the price. For a retainer, apply a slight discount vs your day rate (10–15%) in exchange for regularity. A €600/day rate with 2 days/month gives a retainer at €1,020–1,080/month instead of €1,200. The client saves; you secure the revenue.

4. Automate billing. With a subscription platform, each billing cycle automatically generates a compliant invoice and triggers the payment.

5. Pitch your existing clients first. An email or call is enough: "We’ve been working together regularly. I’d like to propose formalising this with a monthly retainer. Here are the benefits for you."

For European consultants, invoicing is subject to country-specific rules. Key considerations across the EU:

• VAT thresholds: most EU countries have a small-business exemption (e.g. €85,800 in France, £85,000 in UK). Above the threshold, VAT registration is mandatory.
• Mandatory invoice details: SIRET/VAT number, payment terms, line-item descriptions, and sequential numbering are required in most jurisdictions.
• E-invoicing mandates: France requires electronic invoicing by 2027; Italy already enforces it. Other EU countries are following.

A tool that handles recurring invoicing automatically avoids errors and hours of administrative work each month. Each billing cycle generates a numbered, compliant, archived invoice — whether you bill 3 clients or 30.

For consultants with growing revenue, centralising payment and invoicing in a single tool also simplifies year-end accounting and tax reporting.
