It is easy to use Billogram to bill for services where you can utilise the ROT/RUT deductions. When you create the bill, fill in the information necessary for ROT/RUT under 'Deductions and fees'. 

When you have received payment for one or more invoice with ROT/RUT, you can choose to export these invoices, under Reports, to a file you can the upload directly to the Swedish Tax Agency web page.
