A secure client portal for accountants is usually sold on encryption, and encryption is the part you are least likely to get wrong. Transport security is standard, storage encryption is standard, and no small practice is going to out-engineer its vendor on either. The failures that actually happen to accounting practices are duller and more human: a shared login because seats cost money, a document emailed because the portal was awkward that morning, an ex-member of staff who still has access, a client's records sitting in a personal inbox because that is where they arrived. The IRS makes the duty plain for tax professionals in Publication 4557, and it is a duty about practice rather than about a product. This guide separates what the software should do from what your practice has to do, because a portal only closes the gaps it is actually used for.
What the software should give you
Encryption in transit and at rest, individual logins rather than a shared one, the ability to revoke access immediately, and a record of who sent or opened what and when. That last item is the one people forget to ask for and the one that answers the question a year later. None of this is exotic, and a vendor who cannot describe it plainly is a vendor to leave alone.
What no portal can do for you
It cannot stop a client emailing you a spreadsheet, cannot decide how long you should keep a record, and cannot make a certification you do not hold. It also cannot fix a practice that shares one login because the seats are expensive. Those are process decisions, and buying software does not settle any of them, whatever the sales page implies.
The habits that decide the result
Give every member of staff their own login and remove it the day they leave. Send requests through the portal so clients learn that is where things go. Do not accept records by email once the portal is live, because a single exception teaches the client the rule does not hold. Review who has access to what on a schedule rather than when something goes wrong.
Questions people ask about secure client portal for accountants
Does a secure portal make us compliant?
No. It is one control among several and the obligation stays with the practice. Read Publication 4557 for what the IRS expects of tax professionals, and check your own professional body and any client contracts, because a portal purchase does not discharge a duty that was never about software alone.
Is Tickmarko certified to a security standard?
We are not going to dress up what we hold. Documents travel over HTTPS and are stored encrypted at rest by our storage provider. If your regulator or a client contract requires a specific named certification, check what we publish against that requirement before relying on us for it.
What happens to client documents if we stop subscribing?
You can export your clients, documents and engagements at any time while the subscription is active and for 90 days after it ends. There is no export fee. Deciding how long to retain what you export is a records management question for your jurisdiction.
