The best fit depends on your list size, workflow, integrations, budget, and evidence requirements. Are the figures guaranteed?+ No. They are a dated snapshot of public vendor pages and documentation. Open the linked source and verify the current terms before buying or switching. What should every buyer compare?+ Compare the billable set, duplicate and unknown treatment, file limits, retention, exports, status reasons, API limits, and how the tool handles uncertainty. Why is Refresh List listed first?+ Refresh List is the product publishing this reference. Its row documents the current workflow; it is not a claim that Refresh List is best for every team. THE DECISION ## COMPARE THE RECEIPT. CHOOSE THE FIT. Run the same list, ask the same questions, and keep uncertainty visible.
