New US sanctions on Russia are beginning to impact Microsoft´s activities in the country.
Key Microsoft distributors in the country have begun to restrict sales of Microsoft software, warning buyers they must pay for software licenses within strict deadlines or even upfront.
The latest wave of US sanctions affects the duration of credit that can be offered to Russian firms.
As it is usual for Russian suppliers to wait weeks or even months for payment, the sanctions have scope to significantly impact Microsoft sales in the country.
The sanctions were signed into US law in August last year, linked to Russia´s alleged involvement in Ukraine and cyberattacks, but have taken some time to be felt by the likes of Microsoft.
Microsoft´s Russian distributors Merlion and RRC began notifying their customers about the new payment restrictions in November.
It means we could soon start to see a negative impact on Microsoft´s Russian revenues.
"If we do not receive from you documents confirming payment on orders from the defence and energy sectors, the order could be viewed by the vendor as not complying with the processing procedure and rejected," Merlion's notification said.
Merlion, said in its notification to partners that all sanctioned buyers of Microsoft licenses must pay within tight deadlines, or even pay upfront in some cases.
Microsoft has been enjoying strong earnings and revenue growth on the back of its Microsoft Office 365 products and cloud segments.
Microsoft´s shares have gained 43% over the past year.
