If you are not satisfied with our work – simply don’t pay!
We will set out a project plan covering the work to be done in a set period of time, at an agreed price.
What’s missing at this stage is your perception of the quality of the work (it’s likely that you can’t form a precise perception of the quality yet) – so that’s the risk.
There may be some initial out of pockets (which will be detailed) eg buying the budget spreadsheet (that you can use into the future) that need to be met by you.
You can accept the plan & pay the out of pockets or simply decline and walk away, risk-free.
At the end of the project plan timeframe, if you are not satisfied, work stops & you are not required to make the agreed payment.
