New Customer Onboarding Checklist for a Trade Business

By MMD Solutions Ltd · Published · 5 min read

Once a customer has given the agreed go-ahead, make the working arrangements clear before the office starts booking and sending documents. Onboarding is the setup of that relationship, not another sales form or a reason to collect every possible detail.

Set up the customer relationship and the first job without treating an initial enquiry as permission to proceed.

Identify the point at which setup starts

Record the decision or instruction that starts the work and the job or proposal it relates to. Keep the source and document version findable. A request for availability, an enquiry and permission to proceed are different positions; do not let a new customer record blur those distinctions.

For a returning customer, check the existing record instead of creating another contact. Their current site, ordering contact or billing arrangement may have changed even if the name is familiar.

Separate customer, site and contact roles

Record who orders the work, who can arrange access, who receives updates and who handles billing. One person may cover several roles, but that should be explicit. A property manager handling access is not automatically the person authorised to agree extra work.

Keep the organisation, each site and the individual job connected. Collect information needed for the actual process rather than building a speculative customer profile. Check any uncertain contact details against the customer’s instructions before sending information.

Agree the practical communication routine

  • Where do new requests and changes go?
  • Who is the normal business contact?
  • Which updates have actually been agreed?
  • Who confirms dates and access arrangements?
  • What information does the office need for invoice preparation?
  • Who handles exceptions when the usual person is unavailable?

Keep the customer’s agreed route distinct from internal staff notes. Do not promise continuous monitoring or response times the business cannot provide. Leave uncertain points open with a named person to confirm them.

Check one first-job example

Illustrative setup: “Customer C104, job A104. Agency office ordered the work; property manager arranges access; accounts receives the invoice. Office confirms the visit after access is settled. Owner reviews requests that change scope or timing. First progress update goes through the agreed email thread.”

Ask the person handling that first job to explain the next step using only the record. If they need to search the owner’s personal messages, a setup detail may still be missing.

Use existing records and review the first handover

HubSpot documents record properties and associations, illustrating that customer details can be held in linked records. Your existing CRM or job system may already support the setup. Check it before introducing a separate onboarding app or duplicating the same fields in a form and spreadsheet.

After the first job, review unclear contacts, missing references and repeated questions. Update the process where needed. Onboarding is complete when the relevant people can follow the agreed workflow, not simply when every box on a generic template is filled.

Download the working checklist

Download the blank worksheet (CSV). Use fictional details for a trial, then adapt the fields in the system you already maintain. Do not keep a separate spreadsheet just to duplicate a working process. Protect real customer details and share only what the person handling the task needs.

Help shape MMD

Start with a free 15-minute conversation about the admin taking up your evenings. If there is a fit, choose Callback alone or add enquiry, quote and payment follow-up.

Discuss a paid pilot

From £49 for 30 days + £49 standard setup (£98 first payment), before any applicable VAT. Starts on activation. Continuing after day 30 needs your explicit agreement. No obligation to buy or join a mailing list.

Optional analytics

Privacy and offer details

With your analytics permission, MMD also counts completed admin-estimator calculations by day and broad weekly time-saving range. The estimator does not send entered figures, contact details or a visitor identifier. These aggregate counts describe tool use and assumptions, not verified savings. Our hosting provider still processes ordinary request metadata; hashed network counters are used briefly for rate limiting. Google receives the named calculation event. Rejecting analytics keeps this optional measurement off; the calculator still works.

The paid pilot lasts 30 days from activation. Callback costs £49; Callback with either Enquiry & quote follow-up or Invoice & payment reminders costs £68; Callback with both additions costs £87. There is one £49 standard setup fee, making the first payment £98, £117 or £136 respectively. Prices are before any applicable VAT. Standard setup covers compatibility checks, standard configuration, message templates, testing and a handover, with up to one hour of setup time. We confirm availability, compatibility, scope and costs before you agree to start. Each addition includes 50 outgoing SMS segments per service month and normal customer replies. Long texts can use more than one segment. We notify you before the limit and pause additional automated messages at the cap. A £10 prepaid top-up for 100 outgoing segments needs your approval; no automatic overage charges. At day 30 you explicitly choose whether to continue at the same monthly price, held for your first three months. After that agreement, the service renews monthly; you can cancel the next renewal through the billing portal or by contacting us. If you do not continue, we agree how to return call handling to its previous setup. Existing customers pay £19/month per addition and one £49 setup fee to configure one or both additions. Custom integrations are scoped and quoted separately, with third-party fees and any maintenance agreed before work starts. Research participation, marketing and analytics are separate choices. Honest feedback is welcome; no positive review is required and the initial conversation carries no obligation to buy. Callback includes up to 20 voicemail messages or 20 processing minutes per service month, whichever is reached first, for one business number. Each message is counted separately and its duration is rounded up to a whole processing minute: a 20-second message uses 1 minute; a 61-second message uses 2. Messages are limited to 2 minutes. Unused allowance does not roll over. We confirm activation and reset dates, and how calls are handled at the limit, before activation. Extra callback usage must be agreed separately; there are no automatic paid top-ups.
