E-signatures for a small business: when they are binding and how to automate contracts
When an e-signature binds in the US and EU, and a contract workflow from quote to file.
The days after a client says yes decide how the rest of the work goes. This guide sets out the onboarding steps in order for firms that sign clients, such as accountants, law firms, agencies, coaches and builders on larger jobs: which steps to automate, which a person should send, and what to do when a client stalls.

The short answer
Write the steps after "yes" in order: the agreement, the deposit invoice, the intake form, the document list and the first meeting. Automate the sending, the reminders and the filing, so each step starts when the one before it is done. Keep a person on the welcome, the first call and anything that needs judgement, and have a person phone any client who stalls after two reminders.
Most firms already do these steps. The trouble is that they happen by memory, in a different order each time, and the client waits while someone remembers the next one. Write them down in the order they should happen, with what starts each:
The order matters. A law firm that sends an intake form before the conflict check has collected details it may not be able to act on. A builder who books the start date before the deposit clears may hold a slot for a job that never starts.
Automate the steps that are the same for every client and need no judgement:
Keep a person on everything else: the welcome, any question the client asks, any change to scope or price, the result of a conflict or identity check, the first meeting itself, and every client who has gone quiet. The personal touch lives in those moments, not in typing the same email by hand for the fortieth time.
Automated onboarding feels cold when it sounds like a system. It feels personal when every message comes from the person the client dealt with, uses their name, mentions what they care about and asks for one thing at a time. Four habits do most of it:
A welcome a person sends, to copy: "Hi Sarah, great to speak today, and thanks for choosing us. You'll get our engagement letter to sign in a few minutes, then a short form about the business. Once that's back, I'll book a call to go through the year-end. If anything is unclear at any point, reply to me directly. Priya"
Here is onboarding at a small accountancy practice taking on a new limited company client, with the point where a person checks each step:
Each step starts the next, so nobody has to remember. The partner and administrator see one list: which clients are at which step, and who is waiting on what.
For a law firm, the order is stricter and more of the steps need a lawyer:
Automation sends, reminds and files. It never gives advice, never decides whether to take a matter, and never tells a client their documents are fine. Whether the e-signature on the engagement letter is enough is a separate question, covered in e-signatures and contracts.
In every one of these the same rule holds: the system sends and reminds, and a person makes the promises.
Write yours in your own words and read them aloud. If a message would sound odd coming from you in person, rewrite it.
Some clients sign and then go quiet. Plan for it, so nobody chases forever or forgets to chase at all:
Chasing an unpaid deposit is a different job with its own rules, covered in how to automate invoice reminders.
Before building anything, check what your current software does. Practice management software, proposal tools and CRMs may already send agreements, forms and document requests, and switching that on may be all you need. If they do not, a working onboarding can start with:
The automation is what joins them: when the signature lands, the invoice goes; when the form comes back, the document list goes. Each tool's API decides how much of that can be connected, which is worth checking before you buy anything new.
A good onboarding workflow has a clear start, a status for every client, a log of each step and a person at each decision. The checks to build in:
We build these in automation: we write the steps down with you first, check what each of your tools allows, and test the awkward cases, such as a client who signs and then asks to change the scope, before anything reaches a real client.
Onboarding collects more personal data than any other part of the work: identity documents, bank statements, family details, sometimes health information. Ask only for what the work needs, and agree before you start where each item is stored, who can see it and how long you keep it. Identity documents and financial records belong in a secure portal or upload, never in an email attachment or a team chat.
Copy only what each step needs. The person booking the first meeting needs a name and a calendar, not the client's bank statements.
Software that sends the steps after a client says yes, such as the agreement, the deposit invoice, the intake form and the document list, each when the one before it is done, with reminders for anything missing. People still send the welcome, run the checks and the first meeting, and talk to any client who stalls.
A welcome, any checks you must make, the signed agreement, the deposit or first invoice where you take one, an intake form, a document list, the first meeting and your own set-up: the client's folder, record and project. Write them in order, with what starts each step and who checks it.
Send every message in the name of the person the client knows, use their name and one detail from the sales conversation, ask for one thing at a time and make one phone call during the process. Keep a person on the welcome, every question and every change to scope or price.
Send two reminders about a week apart, then phone. Ask what is in the way and offer help that removes it, such as filling in the form together. If a start date depends on it, give a date by which you need it, and stop all automated reminders once you have spoken.
Often fewer than you think. Check your practice software, proposal tool or CRM first, as many send agreements and forms already. Otherwise a checklist in a spreadsheet or CRM, an e-signature tool, a form tool, a secure upload place and a booking link, joined by an automation, cover most firms.
If you take a deposit, decide where it sits and stick to it. Many firms send the intake form when the agreement is signed but hold the start date until the deposit clears. Whatever your rule, state it in the agreement and the welcome, so the client is not surprised.
