Is an offer letter a binding employment contract?

Usually not — and most employers want it that way. Standard offer letters state that employment is "at-will" (either side can end it anytime) and that the letter isn't a contract for a fixed term. If you promise a specific term, a guaranteed bonus, or severance, those terms can become enforceable, so word them deliberately.

What should I include?

At minimum: job title, who they report to, full-time/part-time status, compensation (salary or hourly, and pay frequency), start date, at-will language, and any contingencies like a background check or proof of work authorization. Benefits and PTO are commonly summarized with a pointer to the full policy.

What forms come after the offer is accepted?

Once the candidate accepts, US employers generally need a signed Form I-9 (employment eligibility) and a W-4 (tax withholding) — both are in AttachKit's library — plus any company NDA or confidentiality agreement. You can fill and send those in the same private, on-device flow.

Is this legal advice?

No. AttachKit is a fill-and-sign tool, not a law firm. Employment law varies by state — some require specific wage notices at hire, like New York's and California's — so have counsel review your template once before you reuse it.

Fill an employment offer letter online — free template

An employment offer letter turns a verbal "you're hired" into a clear written offer — the role, pay, start date, and basic terms the candidate signs to accept. A good offer letter sets expectations and heads off "but you said" disputes later, while carefully staying an at-will offer rather than an enforceable fixed-term contract (unless you intend otherwise). AttachKit fills your company name, the hiring manager, and the date from your saved profile so you can send a polished offer in minutes.

Who needs it: Small-business owners, startup founders, and hiring managers extending a job offer — especially teams without an HR department who need a clean, consistent letter for every hire.
