Describe what the customer buys
Write one precise sentence: for this customer, I deliver this result within this time and these limits. Do not start with a legal status or logo. Define what is included, what requires an extra quote and how the customer accepts delivery. Ask a potential customer to explain the offer back to you: hesitation reveals ambiguity.
Write a four-line offer: outcome, deadline, proposed price and exclusions.
Calculate before choosing a regime
The customer’s payment is not your personal income. List purchases, delivery time, communications, prospecting and administration. Use an appropriate official simulator for business charges. Compare several sales-volume scenarios instead of assuming every working hour is billable. Do not choose micro-enterprise status solely because it looks simple.
Repeat the calculation with half as many customers and see which costs remain unchanged.
Prepare checks before starting
Identify the activity and check applicable qualifications, insurance and registration on official sites. The French micro regime still includes invoicing and revenue-record obligations: it does not remove the need to organise evidence. Make a list with question, source, answer and date. Resolve uncertain answers before committing.
Write the three questions most likely to change your regime or pricing choice.
Fictional example: a €300 job needs six delivery hours plus four preparation and communication hours. That is €30/hour turnover before purchases, charges and tax, not €50/hour net income.
Validate the offer and its costs before finalising your regime.
