E-signatures for consultants: get the engagement letter signed before the work starts

The gap between "this looks great, let's do it" and a signed engagement letter is where consulting practices quietly lose money. The client is enthusiastic on Thursday. The letter goes out Friday. It sits unopened through a week of their travel, comes back with a question about the payment schedule, gets re-sent, and is finally signed eleven days after the conversation that sold the work. Nothing went wrong — and you still started a month late on a project you'd already mentally scheduled. Here's how to close that gap.

What consultants actually need signed

A consulting engagement generates a small, predictable set of documents, and almost all of them repeat across clients:

• The engagement letter or statement of work — scope, deliverables, timeline, fees, and what happens if any of the three changes.
• A master services agreement — signed once with a client you expect to work with repeatedly, so later projects need only a short SOW.
• Change orders — the document that turns "can you also look at X" into paid work instead of scope creep.
• Mutual NDAs — usually signed before the first real conversation, covered in how to get an NDA signed online.
• Subcontractor agreements — when you pull in a specialist for one workstream.
• Data-processing or confidentiality addenda — for clients whose legal team requires them.

Every one of those is the same mechanical job: a PDF, a few fields, one or two signers. That's the flow Signed is built for, and the step-by-step is in how to send a document for electronic signature.

The engagement letter is your fastest lever on cash flow

Most consultants try to fix cash flow at the invoicing end. The bigger lever is at the front, because the signature date sets everything downstream — the kickoff date, the deposit invoice, the revenue month. Compressing the signing gap from ten days to one moves an entire engagement's cash forward by more than a week, on every project, with no change to your rates or your pipeline.

It also protects the work itself. An unsigned engagement letter is the single most common reason a consultant ends up arguing about scope in month two: the conversation happened, but the version of it that both parties agreed to on paper was never executed. Getting the signature before kickoff is a discipline, and friction is what breaks discipline.

Never make a client create an account to hire you

The client signing your engagement letter is often a busy executive who will open your email on a phone between meetings. If your signing link asks them to register, set a password, or download something, they'll close the tab and mean to come back. On Signed, they click the emailed link, sign in whatever browser they already have open, and are done — no account, no password, no seat charged to you. The full argument is in why your signers should never need an account.

Template the letter once, send it in ninety seconds

Your engagement letter is 85% identical from client to client — the same terms, the same payment structure, the same signature and date fields in the same places. Set it up once as a reusable template with fields pre-placed and signer roles defined, and each new engagement becomes: swap the scope section, type an email address, send. The workflow is in reusable e-signature templates for repeat documents.

For engagements needing sign-off from two people on the client side — a project sponsor and a procurement or finance approver — set a signing order so each is emailed at their turn rather than all at once; see how to collect signatures from multiple people.

Follow up without being the person who follows up

Chasing a signature is the least pleasant email in consulting. It reads as needy at exactly the moment you want to look in-demand. Automatic reminders do it on a schedule instead, and an expiration date puts a natural deadline on a proposal so the pricing you quoted in March isn't accepted in August. The setup is in how to chase unsigned documents. Meanwhile the status dashboard shows sent · viewed · signed, so you know whether silence means "hasn't looked" or "looked twice and is thinking about the fee" — which are two very different follow-up calls.

The record that matters if scope is ever disputed

Consulting disputes are rarely about whether a signature was forged; they're about which version was agreed to and when. Every completed document on Signed carries a tamper-evident Certificate of Completion — signer name and email, timestamp, IP address — sealed against later edits, so the executed version is unambiguous. The details are in the audit trail explainer and Audit trail & certificate. Keeping the executed copies findable a few years out is its own habit, covered in how to keep signed documents organized.

Signatures collected this way are designed to satisfy the US ESIGN Act and UETA — background in are electronic signatures legally binding?. Signed does not offer online notarization, SMS or knowledge-based identity verification, or EU qualified (eIDAS) signatures, so an engagement with a European client whose counsel requires a qualified signature is outside what we do. Have your engagement letter and MSA reviewed by counsel; this is general information, not legal advice.

What it costs a small practice

Signed is $9.99 per seat per month — one plan, unlimited documents, month-to-month. A seat is a sender, so a solo consultant pays for one and a four-person firm pays for four, regardless of how many clients sign. That flat price is the point for consulting, where document volume swings hard between a quiet quarter and a busy one; the case is in why unlimited documents matters. Signing something yourself stays free forever with no account.

For comparison, DocuSign's published pricing (docusign.com/pricing, checked July 2026 — verify it yourself, pricing changes) lists Business Pro at $45 per seat per month on an annual commitment, with an envelope allowance rather than unlimited sending. For an independent practice, that annual commitment is the harder half of the deal — the reason why is in the annual contract trap.
