Robust Document Handling with Setup Challenges **Rating:** 5.0/5.0 stars **Reviewed by:** Erwinsagesser S. | CEO, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** June 09, 2026 **What do you like best about KlearStack?** I really like KlearStack's ability to handle unstructured data layouts without the need for constant template configurations.

The machine learning models took more upfront time and collaboration with their technical team than anticipated. There are extraction inconsistencies with very low quality or heavily compressed PDFs, which require manual validation to ensure data integrity. I wish the engine were more resilient against low resolution inputs. **What problems is KlearStack solving and how is that benefiting you?** I find KlearStack handles unstructured data layouts efficiently, reducing the need for constant template configurations. It adapts to various document designs, saving our engineering team time on correcting errors or building new rules. It works reliably in the background. ### 2. Accurate Data Extraction, Seamless Integration **Rating:** 5.0/5.0 stars **Reviewed by:** Daniel S. | VP Sales, Hospitality, Enterprise (> 1000 emp.) **Reviewed Date:** May 28, 2026 **What do you like best about KlearStack?** I really appreciate the accuracy of the data extraction with KlearStack. It stands out the most for me. It handles different document formats incredibly well, even when the layouts vary across vendors, making the automation seamless and needing very little manual intervention once it's set up. In the hospitality industry, where we deal with documents from numerous suppliers and vendors with no two invoices looking the same, it's amazing how KlearStack adapts without needing constant configuration. This accuracy gives us the confidence to let the extracted data flow into our system without manual verification, translating directly into faster processing times and fewer errors, which eases the workload on our finance team. Additionally, the integration with our ERP system is seamless, facilitating smooth data flow and connecting well with our finance and accounting software for invoice processing, fitting reasonably well into our existing stack without requiring significant changes on our end. The jump in automation and accuracy compared to our previous manual methods and basic outsourcing is quite noticeable. **What do you dislike about KlearStack?** The initial setup and training phase took longer than we expected, especially for our more complex document types. The onboarding could be smoother. Also, the reporting dashboard could offer a bit more customization. We sometimes need specific metrics that require a bit of a workaround to pull out. Nothing has been a deal breaker but areas where there's room to improve. **What problems is KlearStack solving and how is that benefiting you?** I use KlearStack to automate our document processing, mainly suppliers' invoices.
