I would like to do a payment to multiple addresses in the same transaction on a regular basis. The scenario is this:

  • Collect addresses via QR or string (these may change on each occasion)
  • Use all the collected addresses to send an equal amount of BTC
  • pay an appropriate network fee
  • execute only one transaction

I don't thing QT or multibit can do this, but I could be wrong. If not are there any other software that could do this with relative ease?

Bitcoin-QT can do this. When you click the "Send" tab you will see a button "Add Recipient" at the bottom of the screen.

You can also do it using the RPC interface, with the sendmany command.

  • Out of interest is there a limit? Could I send 500, 5000 or more? – T9b Oct 29 '14 at 10:43

You can do this with Electrum.
See here:

Can I do bulk payments with Electrum?[edit] You can use the CSV import feature to make bulk payments. It can accept either a CSV file or CSV entered into a text box. The rough format is:

"ADDRESS","AMOUNT"  
"ADDRESS","AMOUNT"
