Finance-first client onboarding checklist for professional service firms

Introduction

Onboarding is where commercial discipline meets client experience. A finance‑first approach makes two things non‑negotiable up front: an agreed billing cadence and minimum margin or pricing rules. Use MOUs to set expectations quickly, collect deposits or first payments before work starts, and run onboarding on a cloud‑first model that automates routine tasks and delegates reconciliation. The result: fewer surprises, protected margins, and minimal owner time spent on admin.

Three strategies to implement a finance‑first onboarding

Strategy 1 Gate cash and margin before work starts

• Billing cadence and deposit: Require a clear cadence (retainer, milestone, or periodic invoice) and collect the agreed deposit or first invoice before scheduling work.

• Minimum pricing rules: Enforce margin or pricing floors; flag quotes below threshold for owner approval.

• Payment methods and terms: Offer fast payment options and standardise terms; make late fees explicit.

• Risk checks: For larger engagements, run a quick credit check or request trade references.

Strategy 2 Balance protection with a personable experience

• MOU first, contract later: Use a friendly MOU to set expectations and secure buy‑in quickly; follow with a formal contract for higher‑risk or long engagements.

• Soft stops and hard stops: MOUs and milestone gates act as soft stops; deposits and signed contracts are hard stops when risk is higher.

• Client empathy: Explain why deposits and cadence protect both parties and enable reliable delivery.

Strategy 3 Cloud first, automate, delegate

• Eliminate manual friction: Capture client data in a single cloud intake form and store signed documents in a client portal.

• Automate billing and reminders: Use recurring invoices, payment links, and scheduled reminders to reduce chasing.

• Delegate reconciliation: Assign routine reconciliation and AR follow‑up to a bookkeeper or outsourced provider; owner reviews exceptions only.

• Owner time rule: Owner involvement is decision‑focused: approve exceptions, sign off on below‑threshold quotes, and resolve escalations.

Implementation checklist

• Pre‑engagement gate

  • Issue an MOU or engagement letter stating billing cadence, deposit, and payment terms.

  • Collect deposit or first payment before scheduling work.

  • Run credit checks for larger clients or new corporate accounts.

• Commercial guardrails

  • Embed minimum margin/pricing rules into proposal templates and quoting tools.

  • Add automated warnings for quotes below threshold and require owner sign‑off.

• Client intake and data capture

  • Use a cloud intake form to capture billing contact, ABN/ID, payment method, invoicing cadence, and PO requirements.

  • Store signed MOUs and contracts in a secure client folder or portal.

• Billing automation

  • Configure recurring invoices, retainer management, and payment links.

  • Set up automatic payment reminders and late‑fee rules.

• AR workflows and escalation

  • Define who chases invoices, the cadence for follow‑ups, and the script for each stage (friendly reminder → firm notice → escalation).

  • Create an escalation path for overdue accounts (owner review, payment plan, pause work).

• SOPs and ownership

  • Document short SOPs for intake, MOU/contract issuance, deposit collection, invoicing, and AR follow‑up.

  • Assign owners: intake admin, bookkeeper, account manager, and owner for exceptions.

• Reporting and KPIs

  • Produce a one‑page onboarding health snapshot: deposit collected (Y/N), billing cadence set, margin check passed, client portal access granted.

  • Track onboarding conversion rate, time to first invoice, and AR days for new clients.

• Pilot and refine

  • Pilot the checklist with 2–3 new clients, capture friction points, and refine forms, scripts, and automation rules.
