The Welsh Affairs Committee is looking at how Covid 19 is hitting trade.
Welsh businesses are being asked to share how the Covid 19 outbreak is affecting them.
The Welsh Affairs Committee is gathering evidence which will form part of an inquiry into the Welsh economy and the pandemic.
Answers from the online survey will help inform recommendations to the UK government on what support businesses in Wales need to re-start trading.
Committee Chair, Rt Hon Stephen Crabb MP said: "Whether big or small, in whatever sector, we need businesses in Wales to tell us how they have been affected by Covid-19.
"Thousands of business owners are diligently doing their duty by shutting down their business or implementing social-distancing measures.
"Yet in doing this they are struggling to stay afloat.
"We need their views on the financial support that both the UK and Welsh Governments have offered so far, where the application process could be improved and the help they will need to recover once this pandemic is over."
