Client onboarding for firms that want every new client to start the same careful way

Accounting firm client onboarding automation from signed letter to a ready client file

Taking on a client involves an engagement letter, a client record, a portal invitation and a list of documents to request, and in many firms each piece is sent by a different person on a different day. BoldBellows records the prospect, the services quoted and the responsible accountant before any document goes out, sends only the minimum in each message, keeps tax IDs and bank details out of email and hands any intake answer it cannot place to the person who owns the client, then mirrors the way your firm greets a new client: a signed-up prospect triggers CPA client intake automation that asks the questions your service line needs, sends your own engagement letter for signature, creates the client in your practice software, invites them to the portal, lists the documents you need and assigns the checklist to the responsible accountant. As an accounting firm new client workflow it ends with a client file that looks the same every time.

From $1,350, paid once. CPA client intake automation.

Accounting firm client onboarding automation with CPA client intake, engagement letters sent for signature, an onboarding checklist and a welcome email, built by BoldBellows

What you can verify in Accounting Firm client onboarding

  • Intake by service line only the questions needed
  • Your own letter signed date on file
  • Checklist per client owner on every task
  • Nothing sensitive in email the portal carries the detail
  • Owned exceptions Every blocked record names the person who resolves it
  • One purchase, one result from $1,350, with design, build, tests and documentation in the same price

01 · the first-week problem

A new client's first week sets the tone for the whole relationship

The first week with a client is when the work is easiest to get wrong. The letter waits for a signature, the intake form is half answered, a tax ID arrives in a plain email and the person who was meant to create the file is on leave. Bookkeeper client setup gets done twice, once by the partner and once by whoever notices, and the client wonders why a firm that handles money is so hard to get started with.

Letters waiting for a signature

Nobody noticed the silence.

Intake answers by email

Details were retyped by hand.

Sensitive numbers in plain mail

The portal was skipped.

02 · how it works

How a signed-up prospect becomes a client file that is ready for work

The route judges the change first, then finds the client file by its key and writes only what is missing.

  1. 01

    Read and judge the change

    The Accounting Firm event is verified, its account, resource and time are recorded, and the client request is tested against your written rule.

  2. 02

    Ask, send, wait

    Intake questions go out, the engagement letter follows and the route waits for the signature. The accounting firm welcome email goes out with the portal link.

  3. 03

    Create, assign, track

    The client file is created, the checklist is assigned and every open item is tracked.

The Accounting Firm limits that influenced client onboarding

  • An engagement letter sets the scope

    An engagement letter describes what the firm will do, what it will not do and how it charges, and its wording belongs to the firm, so onboarding sends the firm's own letter for signature and records when it was signed.

  • The firm writes the letter

    The engagement letter is the firm's own document, so the route sends the version you approve and records when it was signed, and never edits its terms.

  • Repair path

    When a write cannot be confirmed, Client Onboarding is searched by the client ID and the engagement before any second attempt.

03 · what ships in the build

An older event arrives after a newer state

The event time is compared with the stored state, so a late Accounting Firm change is logged and cannot overwrite a newer client file.

A prospect never signs the engagement letter

Reminders go out on your schedule, then the file is marked stalled for the partner, and no work is opened until a signature is recorded. The client ID and the engagement is searched and the candidate is compared with what was intended, then one of four results is recorded. Only an absent client file is ever created.

Connect Accounting Firm to Client Onboarding through the client ID and the engagement first; every client file and every repair check depends on it.

Pricing

Build your Accounting Firm to Client Onboarding price

Pick a package, answer three short questions about how Accounting Firm data should reach Client Onboarding, and your price and turnaround move as you choose.


Choose your packageRequired

The three packages differ by how much routing, reconciliation and governance sits around the Accounting Firm to Client Onboarding route.

A focused production route for one Accounting Firm environment and one Client Onboarding destination, delivering accounting firm client onboarding automation with CPA client intake, engagement letters out for signature, an accounting client checklist and a welcome email from one client record with identity and failure controls from day one.

  • One approved Accounting Firm event family and business-state admission rule within the Accounting Client Onboarding service.
  • One authorized account, workspace, organization, or base boundary within the Accounting Client Onboarding service.
  • One Accounting Client Onboarding object contract with field and relationship mapping
  • Stable matching through firm plus prospect, client, engagement, document, transaction, account, reconciliation, tax year, deadline, time entry, or invoice ID and source identity paired with the authoritative accounting client onboarding record, conversation, asset, transaction, document, or decision identifier
  • Tests for duplicates, stale events, malformed data, denied access, and timeouts within the Accounting Client Onboarding service.
  • Implementation map, test record, and premium PDF operations handover within the Accounting Client Onboarding service.

Adds branching, matching and a bounded historical pass for teams whose route into Client Onboarding cannot be one straight-through action, while still delivering accounting firm client onboarding automation with CPA client intake, engagement letters out for signature, an accounting client checklist and a welcome email from one client record.

  • Everything in Signal
  • Up to four approved routing or state-transition branches within the Accounting Client Onboarding service.
  • Existing-record resolution and one bounded historical checkpoint within the Accounting Client Onboarding service.
  • Lookup-before-replay protection for uncertain writes
  • Named exception ownership and a decision-ready evidence packet within the Accounting Client Onboarding service.
  • Field, permission, and destination-state validation before mutation within the Accounting Client Onboarding service.

Adds reconciliation and governance for teams that now depend on accounting firm client onboarding automation with CPA client intake, engagement letters out for signature, an accounting client checklist and a welcome email from one client record, with drift detection and an exception register for Client Onboarding.

  • Everything in Routing
  • Scheduled source-to-destination reconciliation
  • Schema, field, scope, and webhook drift checks within the Accounting Client Onboarding service.
  • Volume-aware retry ceilings and stale-event protection
  • Aged-exception reporting with ownership status
  • Thirty-day release watch and operating review

Within the Accounting Client Onboarding scope, multi-business-unit routing, unrestricted bidirectional synchronization, regulated archives, unsupported extensions, or additional destination systems receive a separate written quote. Third-party subscriptions and usage charges are excluded.

Which Accounting Firm events should reach Client Onboarding?Required

Governed lifecycle set: Use this when several approved Accounting Firm transitions must converge on one Client Onboarding client file.

How should Client Onboarding recognize an Accounting Firm record it has already handled?Required

Ambiguity queue: Route zero-match and multi-match cases to an owner instead of letting Client Onboarding guess.

How much Accounting Firm context should travel into Client Onboarding?Required

Managed repair case: Capture evidence, ownership and a safe next action whenever a Client Onboarding write is uncertain.

How soon do you need it live?Required

Standard follows the schedule your other choices set. Pay to move up the queue and go live sooner.

Optional extrasOptional

Each one begins switched off. Turn on what your rollout needs, watch the total, switch it back off.

06 · process & getting started

Six steps from scattered paperwork to a steady first week

Six steps, each with a named output, take the route from brief to a monitored launch.

  1. Step 01

    Read how clients start today

    We read recent onboarding emails, your letter and checklist and note where new clients wait.

  2. Step 02

    Approve access

    The first task is to open a limited door into Accounting Firm and agree what links one record to another for client onboarding.

  3. Step 03

    Agree the intake and the checklist

    Questions by service line, the letter version, task owners and reminder timing are written out first.

  4. Step 04

    Test the awkward cases

    Repeats, late events, missing values and permission loss are run against a test copy of Client Onboarding first.

  5. Step 05

    Launch with notes

    Going live means starting from an agreed record, so nothing is missed or repeated, then handing over the notes.

  6. Step 06

    Watch the first weeks

    For the first month we review the checkpoint log with you, look at retries and drift, and fix anything the real data reveals.

08 · before we start

Before we begin: what we need

  • Permission to inspect the Accounting Firm fields we will map

  • Your engagement letter, your onboarding checklist, access to your practice software or client list and the e-signature tool you already use

  • Accounting Firm API access and the events you want the route to use

  • A written rule for the client request that counts

  • A named person who owns exceptions and mapping decisions

  • Any existing automations in Accounting Firm or Client Onboarding that touch the same data

09 · security and ownership

Only approved fields travel, and neither product is patched

The build touches the Accounting Firm records that client onboarding depends on, and it leaves every other record alone.

Read-only Accounting Firm to Client Onboarding access: your data stays yoursAn access card for a named viewer being read by a reader that says read-only access.READ-ONLY ACCESSNamed personVIEWER · READ-ONLYID 0042 · 9F2C

Neither product is modified

Accounting Firm and Client Onboarding are reached through their published interfaces; nothing inside either is changed.

Scoped, revocable access

Nothing runs with an administrator's full powers.

Field minimization

Only allowlisted values reach Client Onboarding. Notes, payment details and other Accounting Firm data stay in Accounting Firm.

Repair begins with a lookup

A retry reads Client Onboarding by the client ID and the engagement first, so a doubtful reply never turns into a second client file.

Minimal logging

Retention is short and the content is minimal.

Full handover

We hand across the map, the checks and the contact points for exceptions.

11 · questions

Client onboarding: what firm owners ask

Clear replies to the concerns that come up in almost every conversation.

Is access read-only?Who owns the result?What happens after handover?Can it be changed later?Open any question
Can a standard Accounting Firm automation cover client onboarding?

If you only need a new client who signs, answers and is set up without a dozen emails, a zap will do it. It will not send the letter, track the signature or know what is still missing. Closing those gaps is what this build is for.

Is this CPA client portal automation, and does it replace our portal?

It sits beside your portal rather than replacing it: the route sends the invitation, tracks the upload requests and records what arrived.

Can the accounting onboarding workflow cover tax preparer client intake as well as bookkeeping clients?

Yes, intake questions branch by service line, so a tax client and a monthly bookkeeping client each get the right form.

Does bookkeeper onboarding automation send the engagement letter?

It sends the letter your firm wrote through your e-signature tool and records the signed date; the terms remain yours.

Who decides whether we accept a new client?

The partner does. The route collects the facts and flags anything unusual, and it never accepts or declines anyone.

What does the accounting firm welcome email say?

Whatever you approve: a greeting, the portal link and the list of next steps, without tax IDs or account numbers.

How are Social Security numbers and bank details handled?

They go through your portal and not through email; the route records only that an item arrived.

How do you decide what client onboarding takes from Accounting Firm?

Each Accounting Firm value used by client onboarding gets a destination and a reason, and you sign it off.

Will exceptions be dealt with the way our team deals with them on the Accounting Client Onboarding service?

Yes. Your own conditions are collected during scoping and drive the Accounting Firm client onboarding route, from $1,350.

Who watches Accounting Firm for changes that affect client onboarding?

Every interface is named in the notes. A change upstream halts the affected step and raises a flag, so nothing wrong is written. Later repair work is quoted separately.

Start every new client carefully

Give your firm a first week that feels the same for every client

Give us the starting event for client onboarding, the result you expect and an owner for failures, and we put a fixed price on Accounting Firm client onboarding, from $1,350.
