NDAs, MSAs, statements of work and sign-offs, without the redline limbo
A consulting engagement produces a trail of signatures: the NDA before the first real conversation, the master services agreement once procurement is happy, a statement of work for each phase, change requests when the scope grows, and the client's sign-off on every deliverable. SignMaster keeps each one as a template, routes it to the right people at the client in order, and gives you a sealed record of every yes.

The paperwork of an engagement
| Document | When | Who signs |
|---|---|---|
| Mutual NDA | Before discovery | You and the client contact |
| Master services agreement | Once, at the start of the relationship | The client's authorized signer, then you |
| Statement of work | For each project or phase | The project sponsor, sometimes procurement too |
| Change request | When the scope, timeline or fee changes | The sponsor |
| Deliverable acceptance | At each milestone | The sponsor, with an approve field |
| Subcontractor agreement | When you bring in help | Your subcontractor |
One MSA, many statements of work
The usual structure is a master services agreement that holds the legal terms, like liability, confidentiality, IP ownership and payment terms, and a short statement of work for each project that holds the scope, deliverables, timeline and fee. Negotiate the MSA once. After that, each new phase is a two-page SOW that the sponsor can sign in a day instead of a month.
- 1
Template the SOW
Add fields for the project name, deliverables, milestones and fee. Use checkboxes for optional workstreams and a calculated field that totals the ones the client ticks.
- 2
Route it the way the client buys
Set signing in order: the sponsor first, then procurement or finance, then you. Each person gets the link only when it's their turn.
- 3
Let reminders chase
Set a sign-by date tied to your start date. Automatic reminders follow up so you don't have to send “just checking in” emails.
- 4
File it with the MSA
Every signer gets the sealed PDF with a certificate of completion. Name envelopes by client and phase so the whole history is one search away.
Sign-offs and change requests
Scope creep usually starts with an informal yes. Send a one-page change request with the new scope, the timeline impact and the added fee, and get it signed before the extra work starts. For milestone acceptance, send the deliverable summary with an approve field and a decline field. The sponsor approves from their phone, or declines with a reason you can act on, and either way the answer is in writing.
Drafting with an AI
With Connect an AI, you can ask Claude or ChatGPT to draft an SOW and save it straight into SignMaster as a template with a field on every blank. Read the wording carefully before you send it: the AI wrote it, not your lawyer.
Subcontractors and your own team
When you bring in a specialist, send a subcontractor agreement with confidentiality and IP terms that match what you promised the client, plus a W-9 in the same envelope. On Crew, partners and associates share templates, and roles decide who can send and who can edit the standard terms.
Signers can read the signing page and emails in 6 languages, Spanish, French and Brazilian Portuguese among them. Your contract stays in the language you wrote it.
Pricing for consultants
An independent consultant can run on Solo at $15 a month with unlimited envelopes. Crew is $49 a month for 5 people and adds webhooks and the REST API, so signed SOWs can update your CRM or project tool. New workspaces get 14 days of Crew free. See every plan.
What SignMaster doesn't do
- It doesn't redline or negotiate contracts. Agree on the wording, then send it for signature.
- It doesn't invoice or take payments.
- It doesn't connect to a CRM directly. On Crew and Company, webhooks reach Zapier through its Webhooks by Zapier Catch Hook trigger, and a later step can update HubSpot or Salesforce.
Questions? Answers.
What's the difference between an MSA and an SOW?
The master services agreement holds the legal terms for the whole relationship. Each statement of work covers one project's scope, deliverables, timeline and fee, under the MSA's terms.
Can several people at the client sign in order?
Yes. Add each signer and choose signing in order. The sponsor, procurement and finance each get their link when it's their turn.
Can a client approve a deliverable instead of signing?
Yes. Add an approve field to the acceptance form. The client taps approve, or declines with a reason, and it's recorded on the certificate.
Should I sign an NDA before discovery?
If the client will share anything sensitive, yes. Send a mutual NDA from a template before the first working session.
