A SaaS agreement, also called a software as a service agreement or subscription agreement, is the contract that grants a customer the right to access hosted software for a fee over a set term. It is what a SaaS company signs with each paying customer, and in a typical deal it comes as a bundle: an order form that names the plan, the seats, and the price, a set of subscription terms that governs use and liability, a service level commitment, and a data processing addendum. The deal closes only when the customer's authorized signer executes all of it.
SignSend gets that bundle signed the same day the terms are agreed. Upload the order form, add the subscription terms and the DPA to the same envelope, place the fields, and send it to the customer's signer. They sign from a laptop, it routes back to you to countersign, and you get one executed PDF with a certificate showing who signed, when, and from where. For a SaaS company, that turns a signed order form into recognized revenue without a printer or an overnight envelope in the way. This page covers how a SaaS agreement gets signed electronically, what belongs in the envelope, how a SaaS agreement differs from an MSA, and the questions founders and buyers ask before they sign.
Can a SaaS agreement be signed electronically?
Yes. A SaaS agreement is a commercial contract between two businesses, so an electronic signature on it is valid and enforceable under the federal ESIGN Act and state UETA laws, the same as ink, with no notary required. For most SaaS deals, the executed order form is what a signature attaches to, and the audit certificate records who signed, when, and which version, which is exactly the proof a finance team or an auditor wants when a subscription is recognized as revenue.
There is a second, lighter way SaaS terms get accepted: click-to-agree at signup, where a user checks a box to accept the terms of service. That is also enforceable when the terms are presented clearly and the user takes a clear action to accept. The difference is negotiation and evidence. A self-serve plan can live on click-to-agree, but a negotiated order form with a named signer, a specific price, and a countersignature belongs on a real signature with an audit trail, because that is the document your revenue and your renewals depend on.
SaaS agreement versus MSA
People use the terms loosely, but they solve different problems. A SaaS agreement (or subscription agreement) is built around access to hosted software: it grants a subscription, sets the term and the fees, commits to uptime, and handles data. A master service agreement is a framework for an ongoing relationship where the actual work is defined later in separate statements of work. A pure software subscription usually signs as a SaaS agreement plus an order form. A deal with heavy implementation, professional services, or custom work often uses an MSA with SOWs, sometimes with the SaaS terms attached as a schedule.
| Factor | SaaS agreement | Master service agreement |
|---|---|---|
| What it grants | A right to access hosted software for a fee | A framework for an ongoing services relationship |
| How the deal is priced | An order form: plan, seats, term, and price | A statement of work per engagement |
| Core clauses | Subscription, SLA, data and security, auto-renewal | Scope process, deliverables, acceptance, change orders |
| Best fit | A software subscription, self-serve or sales-led | Implementation, integration, or professional services |
Many companies use both. The MSA sets the master terms once, and each SaaS order form or SOW hangs off it. Either way, the signature is what makes it real, and routing the order form or the SOW through the same signing flow keeps every executed version in one place.
What belongs in a SaaS agreement envelope
A SaaS deal is rarely one file. The commercial terms live on the order form, the legal terms live in the subscription agreement, the uptime promise lives in the SLA, and the privacy obligations live in the DPA. If those get signed separately, you end up with an order form that points at a version of the terms that changed after it was signed. Sending them in one envelope keeps the whole agreement on one version and one execution date, which is what your finance and security reviews will ask for later.
| Document | Why it is in the envelope |
|---|---|
| Order form | The commercial deal: plan, number of seats, term, price, and start date. |
| Subscription agreement | The master legal terms: license grant, use restrictions, warranties, and limitation of liability. |
| Service level agreement | The uptime commitment and the remedy (usually a credit) if it is missed. |
| Data processing addendum | How customer data is handled, required when the software processes personal data. |
| Security or compliance exhibit | SOC 2, HIPAA, or other commitments an enterprise buyer attaches to the deal. |
Auto-renewal deserves its own line. Most SaaS subscriptions renew automatically unless the customer gives notice, and the renewal and notice window should be on the order form the customer signs, not buried where a buyer feels ambushed at renewal.
What SignSend does for SaaS agreements
Built for the founder or account executive who has a verbal yes and needs the order form and terms executed before the quarter closes.
Order form, terms, and DPA in one envelope
Send the order form, the subscription agreement, the SLA, and the data processing addendum together, so the customer signs the whole package in one pass instead of chasing four attachments.
Close the day terms are agreed
The customer's signer opens the envelope from an email link, signs from any device, and it routes back to you to countersign, so a verbal yes becomes an executed contract the same day.
No account for the customer
Your buyer signs without creating a login or installing anything. You are not adding friction to the exact moment the deal is ready to close.
Reusable order form template
Save your standard order form and subscription terms with the fields already placed, then send the next deal in under a minute by swapping in the plan, seats, and price.
Flat pricing, no per-seat fees
Send five order forms or five hundred for one flat price. No per-signer charge and no envelope cap that punishes a good sales month.
Audit certificate for revenue and audit
Each executed agreement carries every signer, the date and time each signed, and the IP address. Keep it with the deal record for revenue recognition, renewals, and your SOC 2 or financial audit.
How to sign a SaaS agreement online
From a verbal yes to one executed order form and subscription agreement.
Upload the order form and terms
Drag and drop the order form as a PDF or Word file, up to 50MB, and add the subscription agreement, SLA, and DPA to the same envelope.
Add signers and place fields
Place signature, printed-name, title, and date fields, assign the customer's signature block, add your own countersignature, and set the signing order.
Send, countersign, and file
The customer signs from any device, it routes back to you, and when the last signature lands you download the executed agreement with its audit certificate for the deal record.
How SaaS agreement signing compares
Most e-signature vendors bill by the seat and cap your envelopes. A SaaS company that closes deals every week should not pay per signer to send an order form.
| Feature | SignSend Pro | Typical vendor |
|---|---|---|
| Starting price | $12/mo flat | $25/user/mo+ |
| Per-signer fees | None | Per seat |
| Order forms per month | Unlimited | Envelope caps |
| Customer needs an account | No | Sometimes |
| Order form, terms, and DPA in one envelope | Included | Higher tiers |
| Custom signing order | Included | Higher tiers on some plans |
| Reusable templates | Included | Higher tiers |

SaaS agreement e-signature questions
Can a SaaS agreement be signed electronically?
Yes. A SaaS agreement is a business-to-business contract, so electronic signatures on it are valid and enforceable under the federal ESIGN Act and state UETA laws, the same as ink, with no notary required. The executed order form and its audit certificate, recording who signed and when, are exactly what a finance team or an auditor relies on when the subscription is booked as revenue.
What is a SaaS agreement?
A SaaS agreement, or software as a service agreement, is a contract that grants a customer the right to access hosted software for a fee over a set term. It usually bundles an order form (plan, seats, price), subscription terms, a service level commitment, and a data processing addendum. It is the contract a SaaS company signs with each paying customer.
What is the difference between a SaaS agreement and an MSA?
A SaaS agreement grants access to hosted software and is priced by an order form. A master service agreement is a framework for an ongoing services relationship, with the work defined in separate statements of work. A software subscription usually signs as a SaaS agreement plus order form, while a services-heavy deal uses an MSA with SOWs.
What should a SaaS agreement include?
A SaaS agreement should include the subscription grant and term, the fees and payment terms, an auto-renewal and notice clause, a service level commitment, data and security obligations (often a DPA), use restrictions, warranties, limitation of liability, and termination. The commercial specifics (plan, seats, price) live on the order form the customer signs.
Do you need both a SaaS agreement and an MSA?
Not always. A straightforward software subscription can close on a SaaS agreement and an order form alone. You add an MSA when the deal includes significant services, implementation, or custom work that gets defined in statements of work over time. Some companies use an MSA as the master and attach the SaaS terms as a schedule.
Is a click-to-agree SaaS signup legally binding?
Yes, when it is done right. A clickwrap acceptance, where the user takes a clear action to accept terms that are clearly presented, is generally enforceable. Negotiated deals with a named signer, a specific price, and a countersignature still belong on a real signature with an audit trail, because that is the document your revenue and renewals depend on.
