What is a website enquiry worth? Include your sales conversion rate
From four additional enquiries to one assumed contract: a worked example with closing rate, net contract value and the costs of changing a website.
A calculation reveals which assumptions would need to hold for a website or shop project to make economic sense. The potential calculator compares your current situation with a scenario you choose.
Choose an assumption you can vary
Online shop economics depend on more than visits. Order rate, basket value and margin affect what remains from additional orders. The potential calculator uses your inputs to calculate a possible difference. It does not predict that a particular design change will actually produce that development.
Start with a baseline whose meaning you understand. Orders and sessions with a purchase can differ. An assumed improvement should also remain recognisable as an assumption. Compare a cautious and higher scenario rather than treating one desired value as certain project earnings.
Compare the same period and keep input meanings consistent. A monthly figure should not sit beside an annual quantity without conversion. If a figure is uncertain, record that uncertainty for the decision. Numerical precision in the result does not turn an estimated input into a measured baseline.
Value enquiries using the closing rate
On a service website, an additional enquiry is not yet an order. Valuing it in euros requires the proportion of enquiries that actually become orders, together with order value and margin. Without this mapping, you can initially consider only the possible number of contacts.
Also consider suitability. If a new page generates more unsuitable messages, it adds processing rather than the intended benefit. Later evaluation should therefore account for enquiry quality. In the calculator, the scenario remains a planning assumption; the business needs to check whether changed contacts fit its offer.
Document assumptions for later comparison. Record the closing rate used and which orders belong in the calculation. Different services may have different values. An aggregate calculation should handle these differences deliberately rather than silently treating all contacts as equivalent.
Include review and rework in time savings
For automation, consider the frequency and duration of the current process. A new solution may shorten steps while professional review remains necessary. Include this remaining work. An hour saved initially means available working time, rather than an automatically equivalent reduction in actual expenses.
Suppose document data is prepared and then checked. The checking belongs in the new workload. Unclear inputs and repeated operations may require extra processing. A realistic scenario includes these cases before comparing development costs and recurring tool fees with expected savings.
Use the calculation to support a decision
The calculator uses euros for inputs and results. Service recommendations may display the selected shop currency; distinguish this display from the scenario calculation. The calculation works with your figures in the browser and replaces neither professional analysis nor a binding project offer.
For the next step, identify which assumption changes the result most strongly. If a small margin change reverses the calculation, examine it more closely before commissioning. An analysis service can investigate the unresolved question; design and development are scoped separately. The calculation supports a question rather than guaranteeing project success.
