eSignature for professional services: from proposal to engagement in one sitting

Where the time goes

In a consultancy, an accounting practice or a small agency, the work itself is rarely what delays a new engagement. The delay is administrative: a proposal sent as an attachment and "looked at over the weekend", terms printed, signed and scanned at an angle, a statement of work that sits waiting for one more signature. Each step is small, but together they push the start date back by a week or two, and a week of unbilled time is real money for a firm that sells hours.

A typical engagement, signed

Most engagements follow the same arc, and each step has a template that opens with its signature fields already placed.

1. Proposal. The consulting proposal frames the client's question, the approach, team, timeline and a fixed fee, with the assumptions the price rests on. The client accepts by signing.
2. Terms. A service agreement or a consulting agreement sets liability, confidentiality and ownership once, for the whole relationship.
3. Each project. A statement of work defines one piece of work under those terms, with milestones tied to payments.
4. Ongoing work. A retainer agreement turns repeat requests into a monthly arrangement with included hours.

Approvals inside the firm

Engagement letters often need a partner's sign-off before they reach the client. On the Business plan, an approver can be added ahead of the client and signing set to sequential, so the client is only invited once the partner has approved. The audit trail records both, which is useful when a regulator or an insurer asks how an engagement was accepted.

Getting paid at the start

Upfront fees and deposits protect a firm from clients who disappear after the first deliverable. With Sign & Pay, the client pays the deposit at the moment of accepting, by card or, through Paystack, by mobile money where it is supported. The payment goes to the firm's own payout account.

Scope creep, handled early

The other quiet cost in services work is scope that grows without anyone agreeing to pay for it. Statements of work with an explicit out-of-scope list and a change-request clause give you a polite, written way to say "that is a new piece of work". When a request falls outside the signed scope, send a short SOW for it the same day. Clients rarely object to a price they approve before the work starts; they object to invoices for work they did not know was extra.

Keeping it tidy

Each document's page shows who has opened, signed or declined it, and unsigned recipients are reminded automatically. Save your engagement letter and SOW as your own templates with the firm's details filled in, and a new engagement becomes a matter of typing the client's name and the fee.
