[Solo Studio](https://help.gosolo.io/solo-studio?hsLang=en) July 28, 2026 # Design Validation Pre-Check With Solo Studio Pre-Check is only needed when using a TPO finance product on the proposal, specifically through GoodLeap or LightReach.  ### What is Design Validation Pre-Check? Design validation is a process that occurs in Solo, when using a TPO finance product, when it has been determined that a design needs to be validated by an expert designer. This process is used to address possible production/design-related roadblocks early on, that may prevent the homeowner from receiving final funding approval.  Before Solo Studio, design validation only occurred when changes had been made to a design that was created by Solo's design team. With Solo Studio, **any design created through the Solo Studio tool that will be using TPO finance products will need to be validated.** Pre-Check allows you to validate your design earlier than credit submission.  Learn more about non-Pre-Check design validation here:  - [LightReach Design Validation](https://help.gosolo.io/palmetto-lightreach-design-validation?hsLang=en) - [GoodLeap TPO Design Validation](https://help.gosolo.io/goodleap-tpo-design-validation?hsLang=en)   --- ### Why Pre-Check? - A design created through Solo Studio will need to be validated before the customer can be approved for their TPO product. - Completing Pre-Check early on can help prevent the need for design changes or change orders during the application process. - If completed early on, can allow you to present a validated design to your customer from the get-go. - Reduces frustration that can occur when changes are needed on designs your customer has potentially already signed for.   --- ### How does Pre-Check Work? Pre-Check can occur at anytime between proposal creation and credit submission, but users will be prompted to complete Pre-Check (if needed) when the proposal is first created: 1. When a proposal is created from a completed design, you will be asked if the customer is using TPO:  1. **If Yes:** It is recommended to submit for Pre-Check now to prevent the need for validation and/or change orders further down the line. 2. **If No:** Pre-Check is not needed, proceed to creating your proposal. This does not prevent you from selecting a TPO product on the proposal. ![Precheck\_UsingTPO\_GIF](https://help.gosolo.io/hs-fs/hubfs/Help%20Center%20Images/Precheck_UsingTPO_GIF.gif?width=670&height=384&name=Precheck_UsingTPO_GIF.gif) 2. If yes, you'll be asked if you'd like complete Pre-Check or to complete it later: 1. **If Yes:** The design will immediately enter the design validation queue & the proposal you receive will be locked until validation is complete. 2. **If No:** Proposal will be generated as normal, but you'll have the option to complete [Pre-Check at a later time](https://help.gosolo.io/adding-pre-check-to-sent-proposals?hsLang=en). ![Precheck\_SubmitNowModal](https://help.gosolo.io/hs-fs/hubfs/Help%20Center%20Images/Precheck_SubmitNowModal.png?width=670&height=488&name=Precheck_SubmitNowModal.png) 3. Once you select your Pre-Check preference, click '**Create Proposal**' to generate your proposal. 1. **If you chose to complete Pre-Check immediately, the proposal will be delivered in a locked state.** This means that no changes can be made to the proposal's design until validation is complete. ![Precheck\_CreatePropModalButton](https://help.gosolo.io/hs-fs/hubfs/Help%20Center%20Images/Precheck_CreatePropModalButton.png?width=506&height=384&name=Precheck_CreatePropModalButton.png)   **Please note**: If changes are made to a validated design, after Pre-Check occurs, design validation will be required again when submitting the application. This only occurs when submitting for a LightReach or GoodLeap TPO finance product.    - [Getting Started with Solo](https://help.gosolo.io/getting-started-with-solo?hsLang=en) - [Users & Permissions](https://help.gosolo.io/users-permissions?hsLang=en#main-content) -
