Karbon is practice management built around the firm's email. You triage the inbox as a team, comment on a message, and turn it into a task on a client and a job. Jobs come from templates, with a status, an assignee, and a due date. Clients get requests and a portal for documents. You record time on the work and create the invoice in Karbon. Contacts, invoices, and payments can sync with QuickBooks Online Accountant or with Xero. The client's books stay in that ledger. Karbon is not where you categorize their bank feed.

Double is the close workspace that writes back to QuickBooks Online or Xero and does not try to be the firm's inbox. TaxDome and Canopy are the tax-season practice systems, with organizers and e-sign aimed at return delivery. Botkeeper automates categorization on the client file. Karbon is the operating layer: who has the email, who has the job, and whether it has been billed.

Firms stay when email is where work goes to die. A shared thread, a comment, and a job status replace the side message that never got written down. Billing sits on the same job, so you can see time against the work without exporting a spreadsheet. You can collect in Karbon and let the ledger update from the sync, or keep invoicing where you already do it.

Share, assign, and comment on email inside Karbon so a message is tied to the client and the job. Integrated email is listed on Team, the entry plan. The pricing page does not name Gmail versus Outlook. Web, iOS, and Android apps are listed.

Triage the firm inbox on the client

Create work from a template, assign tasks, and watch status on a dashboard. The comparison table lists 35 workflow statuses, 40 work templates, and 30 work types on Team. Business raises those caps to 50, 75, and 45. Enterprise lists them as unlimited. Business adds task automation and automatic client reminders.

Run jobs from templates

Send a client request, share documents, and keep the thread on the job. The client portal is listed with tasks and document sharing. eSignature is sold as credit bundles, not included as unlimited signing. A request uses one credit. A request with knowledge-based authentication uses two. Proposals and engagement letters sent through Karbon Engagements do not use those credits.

Ask the client and file the reply

Team includes time tracking, budget reporting, billing, payments, and engagements. Record time where the job lives, then invoice from Karbon. Card payments on the pricing page are 2.6% plus $0.30, premium cards 3.6% plus $0.30, American Express 3.9% plus $0.30, and ACH 1% plus $0.30 capped at $5.

Time the work and send the invoice

QuickBooks Online Accountant: contacts sync both ways, invoices sync from Karbon to QuickBooks, and payments sync both ways. Xero: contacts sync both ways, Karbon invoices sync to Xero, service types can map to Xero accounts, and payments sync both ways, including partial payments. The Business plan is the one that lists industry integrations. The integration pages do not name a plan gate.

Sync invoices to QuickBooks Online or Xero

Karbon puts firm email, jobs, and billing in one place. Team is $59/user/mo annual. Monthly billing starts at 4 users. Quote for Enterprise.

Glean.ai is accounts payable with a record of what each vendor bill was for. You forward invoices to an address Glean gives you. The bill shows up in the app within minutes, and line items (items, quantities, unit prices) are typically added within 24 hours. You approve, then pay by ACH, check, or an international payment. Bills, payments, and prepaid amortization schedules sync to the general ledger. It books accruals and reversals, flags duplicate bills, and lets you open a bill change and see the driver.

Bill.com and Tipalti are built to approve and pay suppliers, Tipalti especially when payees are global and high volume. Stampli is a shared AP inbox. Ramp and Brex put controls on cards they issue. Glean does not issue the card. It reads vendor invoices, and the company says the same workspace covers costs put on credit cards, so finance can ask why a vendor total moved. The only published plan syncs QuickBooks and Xero. NetSuite, Sage Intacct, and Microsoft Dynamics are on the custom plan. Vic.ai is closer if you only want coding automation and you already have a way to pay.

Finance teams keep it when the hard question is why this vendor went up, and whether the bill should be accrued or spread as a prepaid. Unlimited users means a department approver does not add a seat. You still close in your ledger. Glean is the vendor-spend file beside it.

Glean creates an email address for vendor bills. Most invoices appear in the app within minutes of receipt. Line-item detail is typically added within 24 hours. The plans page says you do not key the header or the lines.

Forward the invoice, skip the data entry

Line items are kept so you can look at quantities and unit prices over time, not only the amount due. The product page also lists duplicate-bill detection, renewal notices, variance explanations, and vendor pricing benchmarks.

See why the vendor bill changed

Automated accrual bookings and reversals, and prepaid amortization schedules, are listed on every plan description on the pricing page. Those schedules sync to the general ledger with the bills and the payments.

Book accruals and prepaid schedules

Custom approval workflows are included. ACH and check are marked free on both plans. A USD international payment is listed at $10 plus 0.20% per transaction. FX international payments are marked free. US payment services are provided by Visa Global Services Inc., with Currencycloud named for payment and e-money services.

Approve, then pay from the same bill

Basic shows QuickBooks and Xero. The integrations page says QuickBooks Online and QuickBooks Desktop. Pro adds Oracle NetSuite, Sage Intacct, and Microsoft Dynamics, and that plan has no published price. An extra entity is $50. A historical invoice import is $1.50 each.

Sync the ledger you already close in

Glean.ai captures invoice lines, books accruals and prepaids, and syncs bills to QuickBooks or Xero. This is the AP product, not Glean search.
