Software for accounting firms in 2026, step by step
Six steps of a firm's year, the main pick for each, its backups and the trap to avoid.
The short answer: run the firm in Karbon (Financial Cents if you work alone), collect documents through Liscio, keep client books in Intuit Accountant Suite or Xero, close the month with Double, prepare US returns in Drake and send engagement letters with Ignition. A solo practice can run this stack for about $58 a month plus its tax software; a five-person firm with 40 bookkeeping clients spends about $1,039 a month before tax software. We compared each tool on the real year of a small firm: onboarding a client, chasing documents, closing books, filing returns, getting paid. For each step you get the main pick, a backup and the trap that costs firms money.

One step, one tool, and its backup
Each step opens with what the category does and what to demand, then the main pick (why it wins, where it falls short, the tip that saves money) and its backups. TaxDome, the all-in-one many tax firms shortlist, and Aero Workflow, flat-priced at $108 a month billed annually for 1 to 5 users with no per-user pricing, are the other names you will meet in step 1. If you mostly need a document store, see our guide to document management for accounting firms.
Steps and tools
Run the firm: Karbon, practice management built around the team inbox
Main pickPractice management software is the operating system of an accounting firm. It holds the client list, turns recurring work (monthly bookkeeping, quarterly estimates, annual returns) into jobs with due dates, assigns each task to a person and shows who is overloaded. Most tools add a client portal, document requests, time tracking and invoicing. Before you compare, ask four things: what the billing unit is (per user, per client or flat), whether monthly billing exists for a firm your size, which ledgers it connects to, and what the client sees when you request a document.
Why it wins. Karbon starts from the place work actually arrives: email. Each team member's inbox is connected, so a client's question becomes a task in the right job instead of a message buried in one person's mail. Team costs $59 per user a month billed annually, Business $89. Your client count and document volume do not change the price, which matters once you pass 100 clients. Support by chat, phone or email runs 24/7 on every plan, and UK firms pay in pounds (Team at £34 per user a month on annual billing).
Where it falls short. Monthly billing is only available for teams of four or more, at $79 per user on Team. A three-person firm has to sign for a year. And Karbon is a workflow tool first: card payments cost 2.6% + $0.30 on standard cards, so compare that with ACH before you switch on payments.
Field tip. If you can pay annually, do it: on Team, the gap between $79 monthly and $59 annual is $240 per user a year. Start monthly only if you are four or more and want a trial run through one busy season.

Backup for small firms: Financial Cents, $19 a month for a solo practice
BackupFinancial Cents covers the same ground (workflows, client requests, a portal, billing) with a lighter setup, and its Solo plan is the lowest entry price in this step: $19 a month billed annually for a single-user firm. Team costs $49 per user billed annually or $69 monthly, Scale $69 or $89. A 14-day free trial needs no credit card, and Scale adds integrations with Drake, UltraTax, ProConnect, ProSeries and CCH Axcess.
Where it falls short. Solo does not grow with you: the plan is for single-user firms only, so your first hire moves you to Team. Monthly billing needs at least five users, and it does not mean month to month: every plan is a 12-month agreement, the monthly option only spreads the payments. The month-end close module is an add-on at $5 per client a month billed annually, on top of any plan.
Field tip. Count your bookkeeping clients before you add month-end close: at 60 clients the add-on is $300 a month, more than five Team seats.
- Price
- Solo $19/mo, Team $49/user/mo, billed annually
- Billing
- Per user, close add-on per client
- Best for
- Solo and small firms on QuickBooks
- Limit
- Monthly billing from 5 users

Backup for tax firms: Canopy, practice management with IRS tools on top
BackupCanopy suits a US firm whose year revolves around returns and IRS notices. The base plans include a CRM, document management with e-signature, a client portal, recurring workflows and invoicing: Standard at $74 per user a month and Plus at $109, both billed annually. On top sit add-ons that pure workflow tools leave to others: Tax Resolution at $50 per user a month (IRS transcripts, notice tracking), Tax Workflow Automation from $34 per client credit, and Close Automation at $10 per connected client a month with the first five included.
Where it falls short. The entry price is the highest of the four practice tools, and the add-ons are where the bill grows. Remote e-signature on Form 8879 also needs identity checks, sold at $1.25 per KBA credit. Card payments through Canopy cost 3.30% + $0.20, against 1% capped at $10 for ACH, so push clients towards ACH on large invoices.
Field tip. Price the add-ons on your real client list. Close Automation for 55 bookkeeping clients is $500 a month once the five included connections are used, so a firm that mostly does bookkeeping may pay less with Karbon plus a close tool.
- Price

Backup for deadline tracking: Jetpack Workflow, recurring work on one board
BackupJetpack Workflow does one job: it makes sure no recurring deadline slips. Unlimited projects, clients and templates come on Starter at $49 per seat a month, or $480 a year on annual billing; Premium adds time tracking, budget against actuals and capacity planning at $59 per seat, or $600 a year.
Where it falls short. It is a workflow board, not a full suite: plan on a separate portal and billing tool. Document storage is an add-on ($5 per 100 GB), and the guided onboarding package is a one-time $1,500.
Field tip. Build your templates yourself from last year's calendar before buying the $1,500 package; the onboarding only pays off for firms moving dozens of recurring jobs at once.
- Price
- $49/seat/mo, or $480 a year on Starter

Collect documents: Liscio, a client portal clients actually use
Main pickA client portal replaces email attachments with a secure place where clients upload documents, answer requests, sign forms and message the firm. Ask how a client logs in (app, link, password), whether requests chase the client on their own, and how files are named and filed when they arrive. For portals outside accounting, see our client portal software ranking.
Why it wins. Liscio Platform, at $49 per user a month billed annually, combines client tasks and requests, organizers, Outlook and Gmail integration and secure messaging. File Intelligence alone, at $19 per user a month, reads, classifies and names every incoming file. Tax organizers and deliveries cost $7 each without a bundle, $5 to $4 when you buy ahead.
Where it falls short. Bundles require at least one Platform seat, and identity checks for remote e-signature cost $2 per signer. If your practice management tool already has a portal your clients like, Liscio duplicates it.
Field tip. Buy organizers before tax season: 50 organizers cost $350 one by one and $250 in a bundle, and the same price tier also counts your deliveries.
- Price
- $49/user/mo billed annually (Platform)
- Billing
- Per user, organizers per unit
- Best for

- Limit
- Overlaps an existing portal
- Backup

Backup: SmartVault, document storage wired into tax software
BackupSmartVault is document management first: unlimited cloud storage, client folders and a portal, with SmartRequestAI to request and route tax documents at $15 per return, sold in bundles of 50 ($750) as an add-on to the annual Accounting Pro and Accounting Unlimited plans. Billed annually, Accounting Pro costs $65 per user a month and Accounting Unlimited $85; billed monthly, they cost $85 and $110.
Where it falls short. Every plan has a two-user minimum, so a solo preparer pays at least $130 a month on Accounting Pro. The client experience is a portal, not a task list.
Field tip. Choose SmartVault if your problem is filing and retention across years; choose Liscio if your problem is getting clients to respond.
- Price
- $65/user/mo billed annually
- Billing
- Per user, 2 users minimum
- Best for
- Firms with years of client files

Keep client books: Intuit Accountant Suite, the free hub for QuickBooks clients
Main pickYour clients' books live in their own accounting software, and the firm needs one login to reach all of them. For QuickBooks clients that hub was QuickBooks Online Accountant. It is being retired at the end of 2026, and firms move to Intuit Accountant Suite, which keeps the client list and a shared client inbox, and adds task automations and a standard month-end close, both still labeled beta.
Why it wins. The Core version has no monthly recurring fee and stays free for the firm. For US small businesses on QuickBooks, this is the hub you will open most; clients who outgrow it can read our guide to switching from QuickBooks.
Where it falls short. The paid Accelerate tier is free from 2027 only for Premier and Elite ProPartner firms; other firms pay once the beta ends. Read the terms before you build your close process on Accelerate features.
Field tip. Move before the deadline rather than during your busiest weeks: the switch needs no data migration, and doing it in a quiet month lets you check every client connection.
- Price
- Free (Core)
- Billing
- Per firm; clients pay their QuickBooks plan

Backup: Xero, the ledger UK clients expect
BackupXero is the other ledger most firms support, and the usual choice in the UK. On the US price list, clients pay $27 a month on Early, $59 on Growing and $97 on Established after a three-month discount, and plans renew monthly until cancelled, so nobody is locked in. Payroll powered by Gusto adds $36 a month plus $6 per employee or contractor.
Where it falls short. Early allows only 20 invoices and 5 bills, and invoices created by connected apps can count toward that limit, so most active businesses land on Growing. Supporting both Xero and QuickBooks doubles the setup of every close checklist.
Field tip. Pick one primary ledger for new clients and price the second one higher: each extra ledger means another set of bank rules and reports to maintain. If a client wants to leave Xero, our page on switching from Xero lists the options.
- Price
- Clients from $27/mo (Early)
- Billing
- Per client file, monthly
- Best for

Close the month: Double, close and review across every client file
Main pickClose software sits on top of the client ledgers. It flags uncategorized transactions, sends clients a simple list of questions, tracks each file's close checklist and reviews the books before reports go out. Ask which ledgers it reads, how clients answer questions, and whether it bills per user or per client. Our guide to accounting close software compares the wider field.
Why it wins. Double reads QuickBooks Online and Xero files and bills only connected clients: Core at $10 per client a month, Plus at $25, Scale at $50 (Core is £8 in the UK). You can add as many team members and client contacts as you need for free, so a growing team costs nothing extra.
Where it falls short. You need at least one connected client to subscribe, and the per-client model grows with your book: 60 clients on Core is $600 a month.
Field tip. Mark quarterly clients as quarterly in your settings, but remember that every connected client is still billed monthly; disconnect files you no longer close.

Prepare returns: Drake Tax, professional tax software with a public price
Main pickTax software is a separate purchase from practice management: it prepares federal and state returns, runs diagnostics and e-files. US firms usually license it per tax year. Ask how many returns are included, what each extra return costs, and how many preparers can use the license.
Why it wins. Drake publishes its prices. Drake Tax Online, the cloud version, costs $299.99 for the tax year with the first user included, then $49.99 per individual return and $74.99 per business return; each extra user is $99. On the desktop side, Pay-Per-Return costs $379.99 a tax year with 10 individual returns included, Drake Tax 1040 150 covers 150 individual returns for $1,995, and Drake Tax Pro 250 covers 250 returns of any type for $2,495. Those are retail prices: Drake sells the desktop licenses cheaper before the season ($1,895 and $2,375).
Where it falls short. There is no monthly subscription: it is an annual license, paid before the season. Optional services such as payments and bank products cost extra.
Field tip. Do the break-even math and buy before the season. On desktop Pay-Per-Return, 43 individual returns cost $2,029.66 ($379.99 plus 33 extra returns at $49.99), already more than Drake Tax 1040 150 at its $1,995 retail price. If you also file business returns, compare with Pro 250 instead, which counts both types in its 250.

Win and bill clients: Ignition, proposals, engagement letters and payments
Main pickProposal software turns a price into a signed engagement letter and a payment schedule. The client accepts the services, signs and authorizes recurring billing in one flow, which ends the gap between signed and invoiced.
Why it wins. A client only counts toward your plan once they accept a proposal, and imported clients sit as leads at no charge. Solo costs $39 a month billed annually ($49 monthly) for practitioners under $150,000 in annual revenue, with 20 active clients and one user. Core costs $99 a month billed annually or $149 monthly.
Where it falls short. Extra active clients over your plan's inclusion cost $7 each a month on Solo, falling to $2 on the top plan. Payment processing fees come on top, with an extra 0.3% on the part of any direct debit above $3,000.
Field tip. Run the client count before you pick a plan: a solo firm with 30 active clients pays $39 plus 10 extra clients at $7, so Core's 50 included clients may cost less once you grow.

Build the stack around the billing unit, not the feature list
Software for an accounting firm is not one product. It is a hub (practice management) plus specialist tools around it: a portal to collect documents, the ledgers your clients keep their books in, a close tool, tax software and a way to sign and bill clients. The hub tracks the work; the others do it. So the first rule is to choose the hub, then pick tools that connect to it and to QuickBooks or Xero.
The second rule is to find each tool's billing unit, because it decides your bill more than the headline price: per user (Karbon, Canopy, Liscio, SmartVault), per seat (Jetpack), flat by team size (Aero), per connected client (Double, Canopy Close Automation, Financial Cents close), per return (Drake) or per active client (Ignition). A firm with 4 people and 200 clients should lean towards per-user tools; a solo bookkeeper with 15 clients can afford per-client ones.
Third, read the contract terms: monthly billing often has a team minimum, annual plans have a set term, and tax software is paid per tax year before the season. If you also run payroll for clients, see payroll software for accountants; for engagement letters alone, our proposal software guide goes further.

- Is monthly billing allowed for a team your size, and what does the annual term commit you to?
- Does the tool read QuickBooks Online and Xero, and who maintains the integration?

Questions about accounting firm software
Do tax preparers need a written information security plan?
Yes: federal law requires tax and accounting professionals to create and maintain a Written Information Security Plan (WISP) to protect client data. The IRS offers a template, Publication 5708, aimed at smaller practices. Your software choices (portal, storage, MFA) should appear in that plan, so pick tools whose security settings you can document.How do I get Form 8879 signed remotely?
With an e-signature tool that runs identity verification, usually knowledge-based authentication (KBA). The IRS requires the check every time a taxpayer e-signs Form 8878 or 8879 remotely, and a taxpayer who fails the questions after three attempts cannot sign that way. Count the cost per check in your budget.Is QuickBooks Online Accountant going away?
Yes, Intuit is retiring it at the end of 2026 and moving firms to Intuit Accountant Suite, with no data migration needed. Core stays free; the paid Accelerate tier is in a free beta extended into early 2027, after which only Premier and Elite ProPartner firms keep it free. Plan the move outside tax season and check each client connection afterwards.Do UK accountants need Making Tax Digital software for clients?
Yes, for clients whose qualifying income passes the threshold: £50,000 based on the 2024 to 2025 tax year, then £30,000 and £20,000 in the following two years. Those clients must keep digital records and send updates through software they choose and authorise.Do small accounting firms need audit software?
Only if you perform audits or reviews. Audit software analyzes full ledgers and documents the testing trail; a firm that does bookkeeping, tax and advisory work can skip it and put that budget into close and portal tools.Which practice management software has the best AI?
Judge the AI on one job, not on a demo. Canopy includes its Coworker assistant in every plan with monthly AI credits per user, still in open beta. Liscio's File Intelligence ($19 per user a month billed annually) reads, classifies and names every incoming file. Intuit Accountant Suite runs reconciliation and categorization tasks across clients from a chat prompt, also in beta. Ask each vendor what happens when the credits run out.Can an accounting firm run on spreadsheets and email?
For a handful of clients, yes, but deadlines and documents slip as you grow. Spreadsheets have no task owner, no client reminders and weak access control, which also makes a WISP harder to write. Most practice tools let you try before you pay: Financial Cents runs a 14-day free trial with no credit card, enough to rebuild one month of recurring work in it.Should the firm pay for client ledger subscriptions?
Usually the client pays, but some firms bundle it into a fixed fee. If you bundle, avoid the cheapest plan: Xero's Early plan allows 20 invoices, and invoices sent by connected apps can count toward that limit, so a client with a payment or e-commerce app hits it fast. Price the bundle on Growing ($59 a month after the introductory discount) plus your time.
