Open your paid tools
Decision Pack and Batch Analysis workspace · Project Pack workspace · Complete Job Package workspace
Use the browser and device where you purchased when possible. Purchase access belongs to the selected project and package; buying one package does not unlock the others.
Recover access or saved work
For a Project Pack or Complete Job Package, enter your saved private recovery code in the matching workspace. After recovery succeeds, choose and load the saved online project, then follow the next-step button. Recovery codes restore authorized access and online saves; they cannot restore unsaved edits or files saved only on another device.
For a device save, open the workspace and choose Open a project saved on this device. For a downloaded editable project file, use the import or restore control. A PDF or CSV is an exported document, not an editable project backup.
Package access periods
- Decision Pack: $9 once, seven days, one calculator project with up to five scenarios.
- Batch Analysis: $15 once, seven days, one calculator project with up to 100 scenarios.
- Project Pack: $29 once, 30 days, one project with up to ten calculator sections.
- Complete Job Package: $9 once, 90 days, one job with customer quotes and job documents.
Paid access starts when payment is first confirmed. Project and job online saves can be retrieved for 365 days from purchase; online updates and paid exports follow the shorter package access period. Keep your recovery code and download an editable backup. Downloaded documents remain yours to keep.
Payment or refund questions
If payment appears incomplete, check your receipt and purchase confirmation before paying again. Some payment methods take longer to confirm. Contact purchase support about duplicate charges, missing access, or a refund request; include the receipt reference. Refunds are available for duplicate charges or technical problems that prevent the purchased tool from working as described. Contact support so we can investigate and resolve the problem or arrange an applicable refund. Change-of-mind purchases are not otherwise refundable, except where required by law. A refunded purchase no longer authorizes new paid exports or updates.
