If you need to complete PDFs with user or database information, traditional webforms might not suffice. For simple needs (few fields, no sensitive info, single parties, no tables, no logic), a basic webform solution combined with a PDF filling tool could work. For complex forms, sensitive information, or signatures, consider an all-in-one document solution.

If a branded user experience is a top priority, seek an embeddable solution that gives you full control of branding with custom CSS.

Most e-signature products charge based on packets sent. Find one that only charges you for packets completed.

Document workflows that require information from multiple parties, multiple documents, decision trees, and conditional logic need a solution purpose-built for PDFs with a high degree of customization and flexibility.

Because Anvil is made for people building software for documents, we see new PDF problems every day and are solely focused on building our product to solve them.

Consider the cost of every part of your tech stack involved in automating document workflows. If using multiple tools, account for the technology or engineering resources needed to integrate them. Also, factor in the hours spent on building and maintaining the solution and the opportunity cost of not using that time for core feature development or higher-value work with customers.
