Revenue Forecasting: Turning an Assumption into an Informed Decision

Because opening a point of sale should never rely on a vague estimate. Forecasting revenue is not about "guessing an amount." It is about reducing uncertainty before investing.

Because opening a point of sale should never rely on a vague estimate. Forecasting revenue is not about "guessing an amount." It is about reducing uncertainty before investing.

The Stakes of Revenue Forecasting

In a site selection project, the projected revenue is often the tipping point:

  • The figure that reassures (or does not) a committee,

  • The figure that underpins a business plan,

  • The figure that commits a franchisee for several years,

  • The figure that determines the actual viability of a location.

And yet, in many store networks, forecasting remains:

  • A rule of three,

  • A network average,

  • A field intuition dressed up in Excel,

  • Or an overly optimistic estimate... for lack of data.

A good revenue forecast does not promise the future.

It frames the decision, establishes credible orders of magnitude, and highlights risks.

What Is a Revenue Forecast?

A revenue forecast is a structured estimate of a point of sale's economic potential, carried out before opening (or during a resizing).

It aims to answer a simple but decisive question:

Given the location, the local market, and the retail brand's model, what level of activity can reasonably be expected?

Unlike an intuition or a network average, a revenue forecast is based on:

  • The territory,

  • The potential customer base,

  • The competition,

  • Traffic flows,

  • And, when possible, the network's actual historical data.

It is not a promise.

It is a decision-support tool, designed to inform an investment.

The Logic Behind a Reliable Forecast

A reliable forecast always follows the same logic:

  • Territory potential: How many potential customers are in the area?

  • Site attractiveness: What share of this potential can be captured by this specific location?

  • Competitive pressure: What share is already captured by other players?

  • Retail brand model: Average basket, frequency, positioning, format.

Forecasting involves cross-referencing these dimensions and then translating them into a coherent order of magnitude.

The finer the data, the more robust the forecast.

But even with limited data, a structured approach can already prevent major errors.

The Data That Makes the Difference

Not all forecasts are created equal. Their level of precision depends directly on the available data.

Territorial Data

  • Population within the trade area

  • Household density and structure

  • Income / purchasing power

  • Urban typology (city center, suburbs, retail park)

Traffic Flow Data

  • Pedestrian or vehicle flows

  • Commercial polarities

  • Actual accessibility (access times, barriers, attractors)

Competitive Data

  • Number of competitors

  • Positioning (price, format, specialization)

  • Commercial density

Internal Network Data

  • Historical revenue figures

  • Performance of comparable stores

  • Similar formats

  • Areas with similar characteristics

Maturity Levels of Revenue Forecasting

There is no single universal revenue forecast. There are several maturity levels, depending on the available data.

Level 1 -- Territorial Estimation

Sociodemographic data, trade area, competition. You obtain an order of magnitude, a comparison between sites, and a first Go / No-Go filter. Ideal for prioritizing locations.

Level 2 -- Contextualized Forecast

Territorial data, flows, competition, network benchmarks. You obtain a plausible revenue range, a more refined ranking, and a solid basis for a committee. Suited for structured site selection decisions.

Level 3 -- Advanced Forecast

Detailed internal data, history by format, granular territorial data, calibrated models. You obtain a precise and well-argued forecast, scenarios (conservative / central / optimistic), and a post-opening management tool. Reserved for networks with a solid data foundation.

What You Need

For a Reliable Forecast

  • A precise address

  • A defined trade area

  • Population / income data

  • A competitive mapping

  • Flows or attractiveness indicators

For an Advanced Forecast

  • Historical revenue per point of sale

  • Typology of comparable formats

  • Network performance data

  • History of past openings

The more heterogeneous, outdated, or unstructured the data, the more the forecast should remain cautious and well-framed.

A good forecast is not the one that announces the highest figure, but the one that withstands reality.

Common Mistakes

Common mistakes in revenue forecasting:

  • Using a network average without accounting for the territory

  • Ignoring local competition

  • Overestimating the impact of traffic flows

  • Underestimating cannibalization

  • Confusing theoretical potential with actual performance

  • Failing to explain the model's assumptions

These mistakes create distrust... and weaken decisions.

A Rational Framework for the Field

A good forecast enables you to: secure a real estate investment, arbitrate between several potential locations, negotiate a lease with full knowledge of the facts, and anticipate the break-even point of a new point of sale.
