This article describes what happens when the Soda PDF products expire. There are different options depending on your product.
Soda PDF 360
There are several Soda PDF 360 plans available to users. When a Soda PDF 360 plan ends, your account will be reverted back to the Soda PDF Free.
Soda PDF Free provides users the ability to View and Create PDFs, Merge, Compress, and Print tools.
You can get an Unlimited E-Sign (a yearly package). This allows you to send multiple document packages off for signature.
When this expires, you will no longer be able to send out new document packages. Any packages you had previously sent off can still be signed and you will still have access to all your signed documents and packages from Soda PDF.
