Software for consultants: the consulting stack, step by step

Client management software for consultants does the paperwork between "we should work together" and "paid": a proposal with your scope and price, a contract signed online, invoices, and a portal where the client sees it all. Before comparing, require four things: proposals that turn into contracts and invoices without retyping, online payment, a client portal, and an export of your clients and invoices if you leave.

Why it wins. Bonsai covers that chain in one tool and lists its whole grid. Essentials costs $19 per user per month billed annually, or $25 billed monthly, and adds invoices and payments, proposals and contracts, scheduling (1 event type), forms and the client portal. Premium is $29 billed annually ($39 monthly) and adds integrations with QuickBooks, Xero, Zapier, Calendly and Google, plus the removal of Bonsai branding. The yearly plan is advertised as up to 4 months free.

Where it falls short. The cheapest plan is a trap for a consultant: Basic, at $9 per user per month billed annually, has time tracking, tasks, projects and a CRM, but no invoices, no proposals and no contracts, so you start at Essentials. Elite ($49 per user per month billed annually) requires 3 users minimum, or $147 a month billed annually. Online payments carry processing fees that vary by payment method, on top of the plan. The trial is 7 days, short for a sales cycle: send one real proposal during it.

Field tip. Users in 2026 praise fast support and an easy setup; the complaint that comes back is renewals charged on an account no longer used, so cancel in your settings and keep the confirmation email. To push signed clients into other tools, see the Bonsai integration for Zapier.

Who it's for. The consultant who wants a polished client journey: inquiry form, proposal, contract and payment in one flow, with a scheduler. Starter costs $36 a month on monthly billing, Essentials $59 and Premium $129; annual plans are discounted, with seasonal offers on top. Essentials adds the scheduler, automations, the QuickBooks Online integration and up to 2 team members, where Starter has 2 live lead forms and basic reports. The free trial lasts 30 days without a credit card, and a 60-day money-back guarantee follows. Check your country first: HoneyBook only serves businesses based in the US, Canada, the UK and Australia.

Where it falls short. The monthly Essentials price shows a lower figure for the first 3 months only, then $59: budget the full price. Card fees start at 2.7% plus 10 cents (the plan comparison lists 2.9% plus 25 cents) and bank transfers cost 1.5%, so a $5,000 invoice paid by card costs $135 to $145 in fees. Premium is the only plan with unlimited team members. In 2026, users praise how easy it is and complain about workflows that do not move clients to the next step and a Gmail sync that misses part of the thread: run each automation on your own email before a client sees it. If you are leaving it, see our guide to switching from HoneyBook.

Who it's for. Consultants who sell several services or run more than one brand and want deep custom workflows. Starter costs $35 a month or $335 a year, Premier $55 a month or $525 a year, with unlimited clients and projects on both. Extra brands cost $10 a month each, and users are priced in bands: 4 to 10 users for $25 a month, with 3 additional users free.

Where it falls short. Starter leaves out the scheduler, the automated workflows, public proposals, the bookkeeping integration and Zapier, and allows 1 active lead capture form: most consultants who pick Dubsado for automation, or to sync with their accounting, need Premier. The 21-day trial opens on the Premier plan, so you may build workflows you will lose on Starter. Compare other options in our Dubsado alternatives.

Who it's for. Consultants whose deals are large enough that the proposal itself sells: Qwilr turns a proposal into a web page with pricing the client can tick, analytics on how the client reads it, and acceptance online. The trial is 14 days on Starter, without a credit card. Starter costs $35 per user per month billed annually, or $49 billed monthly.

Where it falls short. It is a proposal tool: pair it with your client tool for invoices and time. Growth, at $55 per user per month, is annual billing only with a 5-user minimum, or $3,300 a year; Scale ($75) requires 10 users. A solo consultant stays on Starter, ideally billed annually: pages you build by hand are unlimited, but "documents" (proposals generated automatically through the API or the AI assistant) include 40 free on Starter, none when Starter is billed monthly, then $2.50 each. Payments collected through QwilrPay carry a 0.09% Qwilr fee on Starter, on top of Stripe's. Our ranking of proposal software for consultants compares it with PandaDoc and others, and our guide to switching from Qwilr covers the move out.

A booking tool gives prospects a link to pick a slot in your real calendar, with the video link and reminders sent for you. For a consultant, it removes the five emails before a discovery call. Require a two-way calendar sync, buffers between meetings and paid bookings if you sell sessions.

Why it wins. The free plan works for a solo consultant: one event type and one calendar connection. Standard costs $10 per seat per month billed yearly, or $12 monthly, and adds unlimited event types and payments through Stripe or PayPal; Teams is $16 billed yearly, or $20 monthly.

Where it falls short. The free plan's single event type means you cannot offer a free 20-minute call and a paid 90-minute session side by side: that is the moment you pay. HoneyBook Essentials includes a scheduler, and so does Bonsai Essentials, but limited to 1 event type (unlimited from Premium): skip Calendly if one of them already covers the calls you sell. See the Calendly integration for Zapier and our guide to switching from Calendly.

A CRM keeps every prospect, conversation and deal in one place, so a referral from six months ago does not go cold. For a consultant, the pipeline is the business: require deal stages, email logging and reminders.

Why it wins. HubSpot's free tools cost $0 a month for up to 2 users and cover contacts, deals, a pipeline and the log of your sales activities, enough for one consultant. They also include 1 personal meetings link, with HubSpot branding: if you only need one booking page, it can stand in for Calendly. Starter starts at $20 per seat per month, with special pricing for new customers that brings it down to $7 per seat on annual billing ($10 on monthly), for a limited time.

Where it falls short. The launch price is for new customers and for a limited time: budget the standard $20 per seat when you renew. Read our HubSpot review before you upgrade, compare it in our best CRM for the self-employed, and the HubSpot alternatives if the price grows faster than your pipeline.

Time tracking matters to a consultant even on fixed fees: it tells you which projects you underpriced. Require a timer, timesheets by project and client, and one-click invoices from tracked hours.

Why it wins. Harvest turns hours into invoices and has a free plan: 1 seat and 2 projects. Teams starts at $9 per seat per month, $108 per seat billed annually, or $11 monthly; Enterprise starts at $14, or $17.50 monthly. The trial is 30 days.

Where it falls short. The price is a base rate: additional invoices, projects, clients and tasks are billed based on what you use, so a busy month costs more than the headline. The free plan's 2 projects run out with your third client, and the accounting and payment integrations that sync invoices and payments with QuickBooks, Xero or Stripe start on Teams. Compare it with Clockify and Toggl Track in our timesheet software ranking. See the Harvest integration for Zapier and our guide to switching from Harvest.

Accounting software keeps your books: bank feeds, expenses, sales tax and the reports your accountant needs. Your client tool sends invoices; the accounting tool reconciles them with your bank. Require bank reconciliation, a sync with your invoicing tool and access for your accountant.

Why it wins. Xero's grid is public and has no per-user license fees, so your accountant logs in at no extra cost. Simple costs $10 a month, Early $27, Growing $59 and Established $97, after an intro offer of 80% off for the first 3 months for new US customers. Subscriptions renew monthly until cancelled. We pick Early for a practice: Simple caps you at 10 invoices and 3 bills, Early at 20 invoices and 5 bills, with real-time reports and a 30-day cash flow forecast. QuickBooks Online is the other name the guides cite; Bonsai Premium and HoneyBook Essentials sync with QuickBooks Online.

Where it falls short. The invoice cap counts more than the invoices you type: invoices created by connected apps may count toward it, so a client tool that pushes every invoice into Xero can hit 20 in a busy month. Growing, at $59, lifts the cap. And once you upgrade, you can move back to a cheaper plan only 1 month later. Project time and cost tracking is only on Established, at $97 a month: track time in Harvest instead. For other accounting options, see our accounting software for the self-employed. To sync paid invoices from other tools, see the Xero integration for Zapier; our guide to switching from Xero covers exports.

Professional services automation (PSA) software runs a consulting firm rather than a solo practice: budgets per project, resource planning, time, and profit per client. It is worth it once several people log time and you need to know which clients make money.

Why it wins. Productive publishes its prices: Essential costs $10 per user per month billed yearly, or $12 monthly, and already includes budgeting and resource planning; Professional is $25 billed yearly, or $29 monthly, and adds rate cards, advanced reports and invoicing integrations. The trial is 14 days without a credit card.

Where it falls short. It is built for teams: every plan requires at least 3 seats, so even a solo consultant pays $30 a month billed yearly; the price calculator opens at 10 users, and paying by wire transfer needs at least 10 seats on an annual plan. The HubSpot integration sits on Ultimate, a plan priced on request. Our ranking of PSA software for consulting firms compares it with Teamwork.com, BigTime and Scoro. Our guide to switching from Productive covers the move out.
