The hourly rate isn't dead: why time recording will become more important in 2026

AI ensures that your work is done faster. This is good for the quality of advice, but difficult for agencies that earn per hour worked. You can already feel that tension in many consulting firms. In this article, you'll learn how billing models are changing, why time registration is becoming more important and what you can already do.

The most important insights

• The hourly rate is not disappearing, but it is losing its monopoly as a standard billing model. Most consulting firms are moving towards a mix of hourly, fixed price and value-oriented models.
• AI compresses delivery times and thus puts turnover under pressure at agencies that invoice on an hourly basis. A consultant who saves 5 hours a week with AI at a rate of €150 per hour costs you €37,500 in billable turnover per year.
• Time registration is becoming more important, not less important, with new billing models. The time sheet is moving from billing tool to internal business intelligence.
• The Effective Hourly Rate (EHR) is the most important profitability measure for fixed price work. Without time tracking, EHR is invisible and you don't know which projects are eating up your margins.
• Scope creep is a silent margin killer for fixed price models. Every unplanned hour is directly deducted from your profit.
• Historical time data forms the basis for future pricing. Each completed project with accurate time data becomes a point of reference for the next quote.

The efficiency paradox: working faster costs you turnover

If your agency charges $150 per hour and AI helps your consultant complete a deliverable in 20 hours instead of 40, you'll lose $3,000 in sales. For the same result - maybe a better result. Industry research shows that AI is already saving professionals 4 to 5 hours per week, with expectations of up to 12 hours per week within a few years. Over a team of 15 consultants, this is rapidly increasing.

The instinctive response is resistance: delaying AI adoption and protecting billable hours. But that doesn't work. Customers know what AI can do and are less and less willing to pay for manual processes when faster alternatives exist. Agencies that don't move along lose work to agencies that do.

So the question is not whether billing models change. They're already doing that. The question is what replaces the hourly rate - and what your agency needs to get through that transition properly.

Where billing models are moving

Hourly billing does not disappear overnight. For secondment, ongoing advice and regulatory work, hourly billing remains logical for both parties. What's changing is that it's no longer the only option. Agencies must control more than one model.

Most consulting firms move along a spectrum, often with different models for different assignments:

• Hourly or daily rate - invoice time spent at an agreed rate. Best suited to secondment, ongoing advice and compliance work. Focus: customer resistance when AI accelerates things and sales shrink with efficiency.
• Fixed price - agreed amount for a defined work package. Best suited to projects with a clear scope, audits and assessments. Point of attention: scope creep quietly eats away at your margins if you don't keep track of actual costs.
• Value-oriented - price linked to business impact, not time. Best suited to strategic advice and transformation processes. Focus: requires strong discovery skills and is difficult to apply to routine work.
• Hybrid or layered - combine elements, such as a fixed base plus performance bonus or a retainer plus project fees. Best suited to complex customer relationships with mixed work types. Point of attention: requires thorough tracking across models.

Value-based pricing: real but not universal

There is a lot of enthusiasm about value-based pricing. Partly right. When a consultant helps a customer save €2 million on purchasing costs, a price of €200,000 makes more sense than hoping it took enough hours to justify the same amount.

But value-based pricing works best when you can quantify the impact in advance. This requires thorough discovery conversations, a good idea of your delivery costs, and historical data that tells you what similar orders actually cost. Without that data, you're pricing on gut feeling — and gut feeling is a bad basis for protecting your margins.

What can you do now?

• Identify which assignments in your current portfolio are suitable for a fixed price or value-oriented model.
• Start with fixed price models for new assignments where the scope is clear and the impact measurable.
• Keep hourly billing where it still works - don't make a dramatic switch, expand your repertoire.

The plot twist: time registration is actually becoming more important

Many office directors assume that time registration becomes irrelevant when billing models are less about “hours times rate”. If you don't invoice on an hourly basis, why keep track of hours?

This is one of the most expensive mistakes a consulting firm can make. Moving away from hourly billing actually makes detailed time registration more important. The difference is that the audience's timesheet changes: no longer a billing document for the customer, but the most valuable piece of internal business intelligence your agency has.

You can't know if you're making money without EHR

With a fixed pricing model, your profitability depends entirely on your Effective Hourly Rate (EHR): the fixed price divided by the hours actually invested. Without time recording, EHR is invisible. A project that looks profitable on the invoice can destroy your margins if the team spends twice as many hours as budgeted.

Two consultants are working on identical fixed price projects. One pays at an effective rate of €400 per hour, the other at €150. You can't improve what you don't see.

You can only measure AI ROI with time data

Your agency has invested in AI licensing, training, and redesigning work processes. But does it deliver? The only way to know is to compare pre-AI and post-AI delivery times for the same types of work. If your team used to spend 40 hours doing a competitive analysis and now 15, that's a measurable improvement you can count on. Without time tracking, it's just a feeling that things are moving faster.

Time tracking is your scope creep warning system

When it comes to hourly billing, scope creep provides more turnover. With fixed price or value-oriented models, scope creep is a silent margin killer. Every unplanned hour is directly deducted from your profit. Real-time insight into hours spent versus budget allows project managers to intervene before profitability is gone — not afterwards.

Historical data makes pricing something substantiable

Each completed project with accurate time data becomes a price reference for the next one. Instead of basing a fixed price quote on what you think it should cost, you know what similar work actually cost — across different consultants, customer types, and complexity levels. That makes pricing something you can substantiate, no longer guesswork.

What can you do now?

• Enter internal time tracking at task level for all current projects - including fixed price projects.
• Calculate the EHR of your last five fixed price projects.
• Compare pre-AI and post-AI delivery times for at least two recurring deliverables.
• Realign internal incentives: reward speed and effective hourly rate, not chair hours.

Conclusion

The hourly rate isn't dead - but it's losing its monopoly as a standard billing model for consultancy. AI is accelerating this shift by compressing delivery times and raising customer expectations. The agencies that come out well here are not the ones that stick to hourly billing. And not those who abolish time recording either. It's the agencies that understand the difference between how they bill their customers and how they measure their own business.

The billing model that you show to your customer is changing. The time intelligence underneath should get better - not disappear.
