PDF generation that's an API, not a sales call.
SimplyFill exists because filling out the same PDF form twice is an offence against productive work. We give engineers a programmable way to map structured data onto fillable PDFs — one template, any volume, no manual labor.
What we're building
SimplyFill is a PDF generation API. You upload a fillable PDF, map its fields once, then POST data to get back a filled, flattened, audit-ready PDF — at any volume, with webhooks for bulk jobs, idempotency for retries, and a signed URL for delivery.
We're optimized for the boring forms that actually matter: HR onboarding (I-9, W-4), tax (1099, Schedule C), legal (NDAs, MSAs), healthcare intake, KYC, and stripe-driven invoicing. The same engine fits all of them because they share a common shape — structured data, predictable placement, repeated at scale.
We don't do call-us-for-pricing. We don't do six-month-pilot. Self-serve sign-up, transparent quotas, docs in lieu of slides.
