Pencil Them In Before You Sign: A Dry Run for a New Client's First Week
The proposal comes back signed. There's a pleasant flurry of messages, a deposit invoice goes out, and then you open the calendar. Where, exactly, is this work going to live?
That question is the whole game. The first week of a new client relationship is not a victory lap — it is a stress test for your capacity. And unlike most stress tests, you can run it in advance, in pencil, before the contract is countersigned.
The week behind the signature
Most small firms price a new client on the billable work: the project, the retainer, the deliverables. Fair enough. But the first 168 hours rarely behave like the rest of the engagement. They are front-loaded with things that don't appear neatly on a proposal: kick-off meetings, account setup, tooling, introductions, contract admin, and the quiet work of learning how another organisation actually operates.
None of that is wasted. It is the foundation. But it does consume hours, and those hours come from somewhere. If you don't decide where in advance, the week decides for you — usually by eating the evenings.
Four buckets that swallow the first week
When we mapped new client onboarding at Project 168, the hours clustered into four buckets. Your firm's proportions will differ, but the categories tend to hold.
Kick-off. Preparation, the meeting itself, notes, and the follow-up email that sets the tone. A two-hour kick-off is rarely a two-hour event; it is often half a day once you count the thinking around it.
Setup. New folders, shared drives, project boards, logins, invoicing details, supplier forms, data protection paperwork. If the client is in a regulated sector there may be UK GDPR documentation, insurance certificates, or procurement portals that require a small ceremony of their own.
Communication rhythm. Deciding who answers what, on which channel, and how quickly. A new client is a new set of expectations. If you don't shape them in week one, they will shape you.
Hidden admin. CRM updates, team briefings, time-tracking codes, the first invoice, and the mental overhead of learning their jargon. Small items, but they add up like parking charges.
The dry run: a pencil, not a pen
Here's the practice. Before you sign — or at least before the start date is fixed — estimate the hours in each bucket and block them in the diary for the first week. Use a separate colour, a separate calendar, or a scrap of paper. The method matters less than the visibility.
Then look at what gets displaced.
If the first week of the new client fits comfortably alongside existing commitments, good. If it only fits by pushing three other deadlines into next week, that is useful information. And if the only way to make it work is evenings and weekends, you have found the real cost of saying yes.
That doesn't automatically mean no. It might mean a later start date, a phased scope, an extra pair of hands, or a setup fee that reflects the real work. The dry run turns a vague sense of being busy into a concrete conversation.
A simple capacity check
You don't need software for this. A notebook will do.
- List the first-week buckets and put an honest hour estimate beside each.
- Compare that total with your genuinely free capacity — not your total working hours, but the hours not already promised to someone else.
- Identify exactly what would move if you took the work.
- Decide: yes, yes with a later start, or not yet.
As a rough guide, if the first week of a new client would consume more than a fifth of your free capacity for that week, treat it as a warning light. It may still be the right client. But you want to know before the work begins, not on the Thursday evening when the team is still setting up folders.
Questions worth asking before the contract
The dry run works better with a few facts. Ask the client how available they are in week one, who the decision-maker is, what onboarding steps they require, and how quickly they expect replies. These are not awkward questions; they are the same questions good clients ask of you.
It also helps to agree a communication rhythm early. A short note confirming channels, response times, and the first review point can save a fortnight of guesswork. Small firms often skip this because it feels like admin. It is actually capacity protection.
When the answer is 'not yet'
Sometimes the dry run says the week is already full. In that case, a delayed start is not a rejection. It is scheduling. Phasing the work, charging for setup, or bringing in a freelancer for the first fortnight are all legitimate ways to carry a new client without dropping the ones you already have.
The first 168 hours of a new relationship tell you whether it has room to breathe. Pencil them in before you sign, and you get to choose the shape of the week — rather than discovering it after the deposit has landed.
