Business contract templates: the six every small business should have

By the BizDocs Studio team · Updated November 1, 2026

Key points

•Most small businesses need six contracts: a service agreement for clients, an independent contractor agreement for 1099 help, a mutual NDA, a statement of work per project, a payment plan agreement, and an amendment form for changes.
•Put the deal terms (fees, dates, notice periods) in one box on page 1 and keep the clauses standard. That is faster to fill in and harder to get wrong.
•A contractor agreement should assign the work product to you, but a signed contract alone does not make someone a contractor. How the work is actually done decides that.
•Chase late invoices in writing on a set timeline: reminder, second notice, final demand. Offer a written payment plan before collections.

Most small-business disputes are not about bad faith. They are about a handshake that meant different things to each side: what was included, when payment was due, who owns the finished work, and what happens when someone wants out. A short written contract settles each of those before the work starts.

This guide covers the contracts a US service business uses most often, what each one must say, and the mistakes that make free templates fail when you need them.

The six business contract templates you will use most

Contract	Use it when	The clauses that matter most
Service agreement	You do work for a client, one-time or ongoing	Scope, fees and payment terms, late charge, changes, acceptance, liability cap, termination
Independent contractor agreement	You hire a 1099 worker or subcontractor	Independent relationship, work product assignment, insurance, W-9, confidentiality
Mutual NDA	You and another business will share pricing, customers or plans	Definition, the four standard exclusions, term, return or destroy
Statement of work	Each project under a service, consulting or contractor agreement	In scope, out of scope, deliverables, acceptance criteria, milestone payments
Payment plan agreement	A customer cannot pay a balance at once	Acknowledged balance, schedule, grace period, default after notice, no waiver
Contract amendment	Anything changes after signing	What changed, revised price and date, everything else stays the same

Two short forms round out the set: a quote acceptance form for small jobs that do not need a full agreement, and a termination letter for ending an ongoing agreement on the notice it requires.

Service agreement template: what it must say

Exact legal names of both parties. "Smith Cleaning" is a brand; "Smith Cleaning Services, LLC" is the party that can be held to the contract.
The services, either in one or two lines or in an attached statement of work.
Fees, deposit, when invoices go out and when they are due (net 15 is common for small service jobs).
A late charge and the right to pause work after written notice if an undisputed invoice stays unpaid.
How changes are approved: in writing, with the price and schedule effect stated, before the changed work starts.
An acceptance window: the client has a set number of days to report a defect, after which the work is accepted.
A limitation of liability, usually capped at the fees paid in the last 12 months, with no liability for lost profits.
Termination for convenience with notice, termination for cause after a cure period, and payment for work done to that date.
Governing law, where disputes are heard, and permission to sign electronically.

Independent contractor agreement: what makes it useful

Free contractor templates often leave out the one clause the hiring business needs most: who owns what the contractor makes. Without an assignment, the contractor may own the copyright in designs, written material, photos or code you paid for.

Assign the work product to your business, and let the contractor keep the tools and methods they had before. That carve-out makes the assignment easier to sign.
Describe an independent business: the contractor controls the means and hours, uses their own tools, may work for others and pays their own taxes.
Collect a W-9 before the first payment and a certificate of insurance before the first day on site.
Skip the non-compete. Many states restrict them. A narrow promise not to use your customer list to solicit your customers is easier to defend.

Classification is decided by how the work is done, not by the title on the contract. If you set the hours, supply the tools and supervise the method, the agreement will not change that. Ask an employment attorney or tax professional when in doubt.

NDA template: mutual or one-way?

Use a mutual NDA when both sides will share something sensitive, such as a subcontract where you share pricing and they share their client list. Use a one-way NDA when only you are disclosing. Either way, check for the four standard exclusions (already public, already known, received from someone else, independently developed), a term of two to five years with trade secrets protected while they stay secret, and a duty to return or destroy information on request. If the other side's NDA has a residuals clause letting them use what they remember, read it closely before signing.

Worked example: three common situations

The sample figures in the pack, one situation at a time

A painting contractor's project. The statement of work prices it at $3,000 in three milestones: 30% ($900) at signing, 30% ($900) when phase 1 is done and 40% ($1,200) on acceptance. The client then adds the upstairs hallway. A contract amendment records it: $3,000 original + $0 previous amendments + $750 this amendment = $3,750, the extra $750 is billed with the final milestone (which becomes $1,950), and completion moves from 11/20 to 11/25.

A cleaning company's late invoice. Invoice 1042 for $1,250.00 was due 10/31/2026, and the agreement charges 1.5% for each full month an amount stays overdue. The reminder goes out on 11/07 (7 days late). The second notice on 11/21 (21 days late) adds nothing yet; it says one month's charge of $18.75 starts on 11/30 if the invoice is still unpaid. The final demand on 12/15 (45 days late, one full month) shows $1,268.75 due by 12/29.

A different customer who owes $4,800 on two invoices and asks for time. They sign a payment plan, pay $800 on signing and 8 monthly payments of $500 from 12/01/2026 to 07/01/2027, with a 5-day grace period and default only after written notice and a 10-day cure period.

Each number above matches the sample figures in our pack, so you can check the math before replacing it with your own. Add a late charge only if your signed agreement or invoice terms provide for one, and count only full months.

Payment plan agreement: put the schedule in writing

A payment plan works when it is specific. List the acknowledged balance, the down payment, each due date and amount, a grace period, and what counts as default. Avoid making the whole balance due automatically on the first late payment; a cure period after written notice usually recovers more money than an immediate collection fight. Say that accepting a partial payment does not waive your rights, and allow early payoff without penalty.

Mistakes to avoid

Signing personally. Sign as the business: name, title, "for Smith Cleaning Services, LLC".
Leaving blanks or unchosen options. Both parties should sign the same finished PDF.
Scope in one vague line with no out-of-scope list. Most payment disputes start here.
Threats you will not carry out in a final demand. List only the steps you are ready to take.
Verbal changes. A two-minute amendment form beats an argument at invoice time.
Copying a template that cites another state's statutes. Use a state-neutral template and add what your state requires.

Signing, including e-signature

E-signatures are widely used for business contracts like these in the US. Use a service that keeps an audit trail, save the completed PDF, and send a signed copy to the other side the same day. Start work only after both sides sign.

Our Small Business Contract Templates Pack has all of the above plus a consulting agreement, three late payment letters and a Start Here guide, editable in Word or Google Docs, with a PDF of each.

Frequently asked questions

What contracts does a small business need?

At minimum a service agreement for clients and an independent contractor agreement for anyone you pay on a 1099. Add a statement of work per project, a mutual NDA before sharing sensitive information, a payment plan for customers who need time, and an amendment form for changes.

Is a service agreement the same as a contract?

Yes. A service agreement is a contract for services. It becomes binding when both parties agree to its terms, usually by signing.

Does an independent contractor agreement make someone a contractor?

No. It records the intended relationship, but agencies and courts look at how the work is actually done. Control over hours, methods and tools matters more than the title on the contract.

How long should an NDA last?

Two to five years after disclosure is common for business information, with trade secrets protected for as long as they remain secret.

Can I sign business contracts electronically?

Generally yes for contracts like these in the US. Use a reputable e-signature service that keeps an audit trail and save the completed PDF. Some document types have special rules, so check if you are unsure.
