Buy the layer that holds the firm together first

New firms usually buy in the wrong order. Tax software and a ledger subscription come first because they are the tools used to produce the work, and practice management is postponed until the client count makes the spreadsheet painful — typically somewhere between thirty and sixty clients, which is exactly when you have the least time to implement anything.

The reason to start with practice management and CRM is that it is the only system that knows about every client, every service, every deadline and every person. The ledger knows one client at a time. The tax software knows one return at a time. Neither can answer 'what is outstanding across the firm this week', which is the question the owner asks every day.

Buying it on day one also costs less in migration pain. Importing eleven clients is an afternoon. Reconstructing the history of two hundred is a project.

A tech stack by category

One choice per category is the target. Two tools doing the same job is where data goes out of sync.

CategoryWhat it doesWhat to look for
Practice management and CRMClients, pipeline, onboarding, recurring work, deadlines, capacity, permissionsRecurring templates, automated client reminders, capacity view, roles and permissions, ledger integrations, pricing that does not penalize adding people
General ledgerClient bookkeeping and financial statementsStandardize on one platform where you can; support for the bank feeds and apps your niche uses

Karbon vs TaxDome vs Canopy: how to compare them

These are all established practice management platforms used by US firms, and each has real strengths. Karbon is known for work management and collaborative email workflow. TaxDome is known for combining client portal, document handling and workflow in one package, with a strong tax-season orientation. Canopy is known for a modular approach where you select the pieces you need.

Rather than ranking them, compare them on the four questions that determine whether a system survives contact with your firm. Does recurring work generate itself accurately, or does someone recreate it each cycle? Can clients be chased for documents automatically, without a person writing the email? Can you see, in one view, who has capacity next week? And how does the price behave when you add a seasonal preparer, a reviewer and an offshore team member?

That last question is where pricing models diverge most. Per-user pricing means every additional person is a budget decision, which is precisely the wrong incentive in January. Confirm current pricing and features directly with each vendor before deciding — published details change.

QuickBooks Online vs Xero for a new firm

Both are mature cloud ledgers and either can run a bookkeeping practice. In the US, QuickBooks Online has the larger installed base, so more incoming clients will already be on it and more local bookkeepers will know it. Xero is often preferred for its interface, unlimited users on a subscription, and strength in multi-currency and certain app ecosystems.

The real decision is not which is better but how many you will support. Supporting both doubles the setup you maintain and the knowledge your team needs. Many new firms accept both because clients arrive with what they have, then standardize new clients onto one and migrate the rest over time. Remindoo integrates with both, so the practice management layer does not force the decision.

Building a cloud-first firm

Decisions that are cheap now and expensive to retrofit at thirty staff.

  • Nothing important lives on a single laptop. If losing a device loses work, the setup is wrong.
  • One place for client documents, with permissions — not folders on a desktop plus attachments in email.
  • Multi-factor authentication on every system holding client data, without exceptions for the owner.
  • A password manager from day one, so credentials are never shared in chat.
  • Written naming conventions for clients, files and entities, agreed before the second person joins.
  • Automated client onboarding as a workflow, so every new client gets the same steps regardless of who signs them.
  • Backups you have actually restored from once, rather than backups you believe exist.

Why firms choose Remindoo

Remindoo is the practice management and CRM layer: client records and pipeline, client onboarding workflows, white-label engagement letters, task and deadline management with automated reminders, team capacity planning, roles and permissions, online payment collection via Stripe, Xero and QuickBooks integrations, email communication and an AI assistant and dashboard.

Remindoo is built by a practicing chartered accountant who runs a 40-person accounting firm, so the workflows come from running a practice rather than from a product roadmap.

That origin shows in the specifics: separate internal and client-facing deadlines because the date you tell a client is not the date the work must be ready; automated document chasing because chasing is the single biggest consumer of junior time; and a capacity view because the question that keeps firm owners awake is not what is due but who can do it.

Remindoo does not prepare or file tax returns, and it has no IRS integration. It sits around the tax and ledger software you choose and keeps the firm itself organized.

Frequently asked questions

What software do I need to start an accounting firm?

At minimum: practice management and CRM, a general ledger platform, tax software if you prepare returns, secure document storage, e-signature, a payment method and professional email. Choose the practice management layer first, because it connects the others.

Do I need practice management software with only ten clients?

You can survive without it, but implementing at ten clients takes an afternoon while implementing at two hundred is a project. Starting early also means your deadlines, onboarding and documents have a consistent history from the beginning.

Is QuickBooks Online or Xero better for a new firm?

Both are capable. QuickBooks Online has the larger US installed base, so more incoming clients arrive on it; Xero is often preferred for interface and user model. The bigger decision is whether you support one or both. Remindoo integrates with both.

How does Remindoo compare with Karbon, TaxDome and Canopy?

All are established platforms with genuine strengths. Compare them on recurring work generation, automated client chasing, capacity visibility and how the price behaves as you add people. Confirm current pricing and features with each vendor directly.

Does Remindoo replace my tax software?

No. Remindoo manages clients, work, deadlines, documents, capacity and payments, and integrates with Xero and QuickBooks. Returns are prepared and filed in your tax software; Remindoo offers no e-file or IRS integration.

How many tools should a new firm run?

One per category. Duplicating a category is how client lists, deadlines and document versions diverge, and reconciling that manually consumes exactly the time the software was bought to save.
