An offer letter is a small document with a lot riding on it: title, start date, compensation, reporting line, and often a deadline for the candidate to sign before the offer expires. When you're hiring for more than one role at a time, the letter's structure barely changes between candidates, but re-typing each one carefully — and re-checking dates and figures under time pressure — is where HR teams lose an afternoon they don't have.
To fill out employment offer letters faster, start from one letter template, save each candidate's role, start date, and pay as a profile, then let an AI form filler auto-fill the repeating fields while you confirm what's specific to that hire. Filly AI does this from a template or your own letter, then sends a no-login e-sign link.
How much time does slow onboarding paperwork actually cost?
SHRM's benchmarking data puts the average cost of onboarding a new hire at roughly $4,100, with a meaningful share of that tied up in manager and HR time rather than the hire's salary itself. Paperwork that takes longer to prepare and get signed pushes back a candidate's start date and adds to that cost before they've done a day of work.
Which fields on an offer letter actually change per candidate?
Name, title, start date, salary or rate, and reporting manager are almost always unique to that hire. The legal boilerplate, benefits summary, and at-will or contract language typically don't change hire to hire. Filling from a saved candidate profile handles the first group automatically so HR only checks the fields that are genuinely one-off.
Can I use our own offer letter template, not a generic one?
Yes. Start from the offer letter template in Filly's library or upload the company's existing letter — the AI detects its fields either way, so legal-approved language doesn't need to change to get the benefit.
How does a candidate sign an offer letter without printing it?
Send a no-login link once the letter is filled. The candidate opens it in any browser, reviews the terms, and signs electronically — no account required, and HR receives the signed copy automatically without chasing a scanned PDF over email.
What else fits the same pattern during hiring?
A job application form earlier in the process and onboarding documents afterward follow the same shape — recurring structure, candidate-specific details. Once a candidate's profile exists, it carries through the rest of their paperwork; see how contracts fill and reuse client details for the same idea applied more broadly.
Frequently asked questions
Is filling out offer letters with Filly free?
Yes, up to the free plan's 10 documents a month, no credit card required. Paid plans from $19/month raise the limit and add batch fill for hiring several people at once.
Can we send offer letters to multiple candidates in one batch?
Batch fill (a paid-plan feature) applies one offer letter template across several saved candidate profiles in a single run — useful for a hiring cohort starting the same week.
Does the candidate need a Filly account to sign?
No. The e-sign link works in any browser without requiring the candidate to create an account.
Is an offer letter filled this way legally binding once signed?
A properly completed and signed offer letter can be enforceable, but specific terms and requirements vary by jurisdiction and role type. Filly fills documents; it isn't a substitute for review by employment counsel on your letter's language.
