A fourteen-week engagement covering research, design, build and handover for the booking flow and the confirmation emails.
Valid for 30 days from the date above. Every figure in this sample proposal is invented.
"People start a booking on their phone and finish it by calling us."
"We cannot change the confirmation email without a developer."
"Nobody can tell me where in the flow we lose them."
| Problem | Who it hits | Cost of leaving it |
|---|---|---|
| The phone flow breaks at payment | Mobile visitors | ~40 calls/week |
| Emails need an engineer to change | Marketing | ~6 days/quarter |
| No step-level measurement | Everyone | Unquantified |
Figures are your own, as given in the briefing call on 2 October. We have not independently verified them.
