You send proposals, invoice after approval, and wait an average of three weeks before you can begin.
Thomas is a brand strategist. He works on a project basis: a positioning programme at €2,400, a brand audit at €600, a sparring session at €150. He sends proposals by email, invoices after approval, and waits.
Send proposal → client agrees → send invoice → wait for payment → start work. Average lead time from agreement to start: 21 days. With three running projects, €3,000 to €5,000 is permanently outstanding. That is not revenue — that is a loan to his clients.
Thomas does not have a cashflow problem in the traditional sense. He has a structural delay between the moment a client says yes and the moment he can start working — and get paid. Every outstanding invoice represents trust he extends that he never consciously offered.
Thomas creates a product for each service. In his proposals, he replaces "please transfer to account number..." with the checkout link. The client clicks, pays, and Thomas knows immediately that he can start.
Thomas creates products for each offer with a clear description on the checkout page. He places the checkout link in his proposals, email signature, or LinkedIn bio. After payment, the client receives a confirmation with Thomas' Calendly link for the intake call. Thomas gets a notification with all client details. VAT data — including company information and VAT number for B2B clients — is captured automatically.
Thomas' average lead time drops from 21 days to zero. His outstanding amount drops from €3,000–€5,000 to zero. He saves at least five hours per month on follow-up. bookto checkout costs him €7 per month.
A payment link sends money. bookto checkout sells something. The client sees what they are buying, confirms the purchase, and receives a confirmation. Thomas does not just know that someone paid — he knows what they paid for. That distinction matters when you offer multiple services at different price points and need a clear record of what was agreed.
