What a Basic Service Agreement Must Contain
Why this matters
Most payment disputes are really scope disputes, and most scope disputes trace back to an agreement that never pinned down what "the job" was. A basic service agreement does not need to be long or full of legal language to protect you. It needs the handful of elements that turn a conversation into a deal a court would recognize. Miss one of them and you may have paperwork that looks official and binds no one. This is the skeleton.
The skeleton: six things, or it is not an agreement
A basic service agreement is the front of the page, the deal itself. Six elements carry it:
- Who - the parties, correctly named.
- What - the scope, described, not just named.
- How much and when - the price and the payment terms.
- When - the timeline.
- What you promise after - a pointer to the warranty.
- Assent - signatures and a date from both sides.
The protective clauses, liability limits, dispute terms, the fine print, ride on the back of the page and get their own article. Miss those and you are exposed. Miss one of the six above and you may not have an agreement at all.
Who: name the parties so they cannot wriggle
Identify both sides fully: your legal business name (not just a logo), and the customer's full legal name plus the service address. This matters more than it looks. If you sign with "the homeowner" and it turns out the person who hired you is a tenant with no authority to authorize the work, you can lose the right to get paid or to lien the property. Name who is actually agreeing, and confirm they have the authority to agree.
What: describe the scope so it cannot be argued
Scope is where agreements live or die. "Perform repair" is not scope; it is an invitation to argue. Describe the work concretely: what you will do, in what area, to what standard, and, just as important, what you will not do. State the conditions that would change the job (hidden damage, a required code upgrade, something you cannot see until you open it up) and note that those trigger a written change order. A scope that names its own exclusions is the single most protective sentence in a small-shop agreement.
How much and when: price and payment terms
Put the price and the payment terms in plain numbers and dates:
- The price, or the pricing method if it is time-and-materials (your rate and how materials are marked up).
- Any deposit, described as a share of the total, and whether it is refundable.
- When the balance is due, on completion, on a schedule, or by a set number of days after the invoice.
Vague payment terms ("pay when done") give a slow customer all the room they need. A due date is a term; "soon" is not.
When: a timeline both sides can hold
Give a start window and an expected completion. It does not have to be a guarantee, and you should say so if it is not ("weather and material availability permitting"). But an open-ended timeline leaves the customer able to claim you abandoned the job and leaves you unable to show you performed on time.
Assent: signatures and a date
An agreement becomes binding when both sides show they agreed. That means a signature and a date from the customer and from you. An electronic signature counts in most places if it is done properly. Unsigned, even a perfect document is just a proposal. Both parties keep a copy.
One page is plenty; a missing piece is not
A basic agreement can fit on a single page. Length is not the measure, completeness is. Before you consider it done, check that all six elements are present and that the scope names its exclusions. Have a local attorney review your standard template once so it fits your state, then reuse it.
The difference between this and a receipt
A receipt records that money changed hands. An agreement records what both sides promised before it did. If your only paperwork is an invoice, you have proof of a charge but no agreed scope, no payment terms the customer accepted, and no warranty on record. The agreement is the promise; the invoice is the proof of payment against it.
