What is Karbon?
Karbon is practice management software for accounting firms. Its website presents solutions for small, mid-sized and large firms, as well as bookkeeping and tax practices. The product connects email with workflow, so client conversations, tasks and jobs sit together, and it adds workflow automation, time and budgets, billing and payments, and document management.
On the client side, Karbon offers client requests and a client portal called Karbon for Clients, which also has a mobile app. According to Karbon's site, clients reach their requests through a unique emailed link instead of a password, and firms can require two-factor authentication. Clients can upload files, see the status of their work, and complete approvals and e-signatures.
Karbon says it can send client requests on a schedule and follow up automatically when one is incomplete. Its document management connects with Dropbox, OneDrive including SharePoint, or Google Drive, or you can use Karbon's own storage. Karbon also lists AI features, mostly for summarizing and drafting email and client updates.
Why firms look for a Karbon alternative
Karbon is designed to run an accounting firm's daily work, and it is a strong choice for that. Firms that search for a Karbon alternative in the context of document collection usually have a narrower need. They are not unhappy with workflow software in general. They want fewer rounds of chasing before a client's file is complete.
Common reasons include the following. The firm is small and does not need team workflow, shared email or time tracking. The firm is not an accounting practice at all, and Karbon is built for accountants. Or the firm already sends client requests but still spends time opening each upload to find blurry photos, missing pages or statements for the wrong period, since Karbon's site does not describe automatic checks on uploaded files.
In each case the firm is looking for a tool that does the collection step well and leaves the rest of its setup alone. That is a different purchase from practice management software, and it is fair to compare the two only on the part they share: asking a client for documents and getting usable files back.
How DocAsker works as a Karbon alternative
You build a checklist of the documents you need, from a ready-made one or from scratch. Each item can include an instruction, an example and the checks that apply, such as a required date range, a signature or a minimum validity. You send the client one secure link. They need no account, password or app, and the link works on any phone or computer.
Each upload is checked by AI as it arrives. DocAsker reads the file for image quality, document type, dates and periods, filled-in signature fields and completeness. When a check fails, the client sees why in plain words, for example that a bank statement covers the wrong months, and can upload a better file straight away. Your team sees files that passed, plus anything flagged for review.
- Reminders follow the schedule you pick, by email on every plan and by SMS on Pro and Firm.
- Each reminder lists only the items still missing or waiting for a retake.
- Reminders stop on their own when the checklist is complete.
- Accepted files are renamed to a consistent pattern and filed to the DocAsker workspace, or to Google Drive, Dropbox or OneDrive on Pro and Firm.
Karbon alternative for accounting and bookkeeping firms
Consider a bookkeeping firm closing the month for 40 clients. On the first working day, each client gets a DocAsker link asking for last month's bank and credit card statements, payroll reports and any loan statements. A client uploads a statement for the previous month by mistake. DocAsker compares the period with the request, explains the problem, and the client uploads the right one.
At year end, the checklist grows: full-year statements, fixed asset purchase invoices, signed representation letters. Signature checks catch the letter that came back unsigned, and completeness checks catch the 12-page statement that arrived as 9 pages. Your accountants start the job with a complete folder. What you need will differ by client and jurisdiction, so adjust each checklist before sending it.
If your firm runs on Karbon, this does not have to change. Keep work, email and billing in Karbon, send the DocAsker link from your usual client email, and have accepted files filed to the Google Drive, Dropbox or OneDrive account your team already uses, renamed to one consistent pattern.
DocAsker vs Karbon: key differences
Automatic checks vs team review
With Karbon, clients upload files against a request and your team is notified, then someone opens the files to see whether they are usable. Karbon's site does not describe automatic checks on what was uploaded. DocAsker checks every file on arrival for blur, glare and cut-off edges, document type, dates and periods, signatures and missing pages. A failed check goes back to the client with the reason, so the retake happens while they still have the document in hand.
One job vs the whole firm
Karbon ties together email, workflow, time and budgets, billing and payments, document management, e-signatures and a client portal. That is valuable when a team of accountants needs one view of all client work. DocAsker handles one job: collecting documents and checking them. It has no workflow, billing or e-signature features. It is a much smaller product, which also means there is little to set up and nothing else to migrate.
Who it is built for
Karbon is built for accounting firms, and its features assume accounting work: repeating client work, email connected to workflow, time tracked against budgets. DocAsker is built around the document request itself, so it serves accounting and bookkeeping firms as well as immigration consultants, law firms, compliance teams, agencies, HR teams and mortgage brokers. If your practice is not an accounting firm, a document collection tool is usually the closer fit.
When Karbon may suit you better
- You run an accounting firm and want email, workflow, time, billing and client requests in one system.
- You want client requests sent on a schedule and followed up automatically from the same system that holds your client work.
- You need e-signatures and client approvals in the same place as document requests. DocAsker does not offer them.
- You want clients to have a portal and mobile app where they can follow the progress of their work.
When DocAsker is the better Karbon alternative
- You need document collection only, and a practice management system is more than you want to adopt.
- Your team loses time on files that have to be requested twice: blurry photos, wrong months, missing pages, unsigned forms.
- You want every reminder to name exactly what is still missing, and to stop when the checklist is complete.
- You are not an accounting firm, or you collect documents such as passports and IDs where validity dates matter.
How to switch from Karbon to DocAsker
- 1
Rebuild your requests as checklists
There is no automatic import from Karbon. Take the items from the client requests you send most often and rebuild them from a ready-made DocAsker checklist or a blank one. Add an instruction, an example and the checks each item needs.
- 2
Send new document requests from DocAsker
Use DocAsker links for new document requests and let open Karbon client requests finish as they are. Choose a reminder schedule. On Pro or Firm, connect Google Drive, Dropbox or OneDrive so accepted files are renamed and filed where your team expects them.
- 3
Keep Karbon for workflow if it works for you
Karbon does much more than collect documents. Most firms that use it for email, jobs, time and billing can keep doing so and use DocAsker only for the collection step. If you leave Karbon completely, arrange other tools for those jobs first, because DocAsker does not replace them.
