Key takeaways
- No single product wins on the sources I checked, so choose by workflow.
- Judge the tool on item-level request status, not on how its folders are organized.
- Set retention by document category, since the IRS gives 3 years and 7 years for different records.
- Ask for the date range of any SOC 2 report, not only the vendor's logo.
The roundups disagree
Search this question and you get a stack of roundups. The ones I checked name SmartVault, TaxDome, CCH Axcess Document, FileCenter, SuiteFiles, Financial Cents, Canopy and Karbon, and they do not agree on a winner. Several are written by the vendors they rank, and their price figures do not match. Treat any ranking without a date, a method and a disclosure as an opinion.
The products fall into four groups: dedicated document repositories, tools tied to a tax suite, all-in-one practice platforms, and collection tools built around client requests. Pick the group that matches the work first. Then compare two or three products inside that group. Decision rule: if the firm files its own electronic returns and needs Form 8879 signatures, put signing support on the first filter and drop any product that cannot store the signed form.
Storage and collection are different jobs
A repository answers where the 2025 bank statement for this client is. It organizes files by client, engagement and year, keeps versions and sets permissions. It does not know that the statement is still missing, or that the client promised it after the 15th.
A collection tool answers which items are still open for this client, who owes them and when the next reminder goes out. Each item carries its own state. The request model in Usual uses to do, submitted, redo, approved, not applicable and will send later, so a client with no brokerage account can close that item without another reminder.
Run this test in the demo. Ask the vendor to show every missing Form W-9 for 2026 across all clients. A repository needs a folder search for each client. A collection tool should return one list.
Criteria, and the test for each
Client portal. Ask whether a client can upload from a phone without creating a password. Ask whether a one-time code is required for sensitive requests, and whether the link stops working when the request closes. Test it with a photo of a bank statement taken on a phone, not a PDF made on a desktop.
Request tracking. The item is the unit, not the folder. Check for item-level status, a completion percentage per client, reminders that pause for one item, and a not applicable option that asks for a reason. A client who had no brokerage account should drop out of the reminder list the day they mark that item not applicable.
Retention. The IRS does not give one number for everything. Its guidance says to keep records for 3 years if the longer situations do not apply, and for 7 years if you file a claim for a loss from worthless securities or a bad debt deduction. Set the rule by document category inside the tool. Then ask the vendor how a deletion is logged and whether a legal hold stops it.
E-signature. For Form 8879, the IRS says the form is completed when the Practitioner PIN method is used, or when the taxpayer authorizes the ERO to enter or generate the taxpayer's PIN. Ask whether the tool stores the signed form as a file that can sit with the return. A product that signs only generic agreements leaves that step to a manual process, and the firm should know that before it buys.
Security: what a SOC 2 report does and does not tell you
The AICPA describes its SOC offerings as assurance reports that CPAs can provide, and it has published an exposure draft for proposed 2027 SOC 2 Trust Services Criteria. Ask which criteria version the vendor's report covers, the period it covers, and whether it covers the product you will use or a parent company. A logo on a website is not a report.
Ask also for the MFA options for staff and for clients, the region where the data is stored, and whether uploads are scanned before staff open them. An answer of in the cloud is not a region. Write each answer into the vendor file with the date you got it.
Form W-9 is the most sensitive routine document in a collection workflow. The IRS says the form is used to give the payee's correct taxpayer identification number to the person who is required to file. Keep it in a restricted folder, not an email thread, and check that the vendor record matches the form before the first payment.
Pricing: model the bill at your real client count
Vendors price in a few ways: per user, per active client, flat by team size, by module, or by quote only. The comparison I checked calls out tier cliffs and annual upfront billing as the two cost items that change a bill most.
Worked check. Count the firm's active clients and staff seats today, then add the clients you expect to onboard before March. Ask for the price at both numbers, and ask where the next tier starts. A per-user price that looks low at four seats can cost more than a per-client price once the active list crosses a tier boundary. Send the vendor this exact question: “What is the total at my current active client count and seat count, and at the count I expect in 90 days, and where does the next tier start?” Put both totals on one page before you compare.
Ask whether temporary seats in peak months are billed by the month or at the full annual rate. Get the answer in writing before you sign an annual contract.
A two-week trial with one real recurring request
Use the 1099 vendor list for the trial. It exercises every feature that matters: one item per vendor, a W-9 upload, a payment threshold check and a reminder schedule. Load five vendors with real 2026 payments so far, and note the vendors under $2,000 year to date, since they can cross the line before year end.
Check four things. A client can upload a W-9 from a phone. A vendor marked not applicable drops out of the reminder list. A will-send-later date pauses reminders until that date. The export lists each item with its status and the date it was received.
Time how long it takes a staff member to answer which vendors have not sent a W-9. If the answer needs more than one screen, the tool tracks documents, not requests.
Failure modes and fixes
The W-9 arrives as an email attachment, and nobody links it to the vendor. Fix: make the W-9 an item for each vendor, so an upload has a place to land and a status to change.
One retention number is set for every folder, so a closed client's files and the current year's statements are purged on the same date. Fix: set a rule for each category, write the reason into the firm's retention policy and place a legal hold before a dispute starts.
A vendor has no TIN and the file is treated as complete. Under IRS Topic no. 307, backup withholding applies at a flat 24% rate when the payee does not provide a correct TIN when required. Fix: keep the item open with a missing TIN status, and hold the vendor's next payment in the bookkeeping system until the item is closed.
The 1099 rule to load into the request
For payments made in 2026, the Form 1099-NEC threshold is $2,000 per payee. The IRS instructions say the $2,000 amount applies to tax years beginning after 2025, and that it may be adjusted for inflation beginning in calendar year 2027. Payments made in 2025 fall under the earlier rule, so check the 2025 instructions rather than copying last year's threshold into the template.
Forms 1099-NEC for 2026 payments are due to payees and the IRS by January 31, 2027. Because that date is a Sunday, the deadline moves to Monday, February 1, 2027. Set the request due date in early January, so the firm has time to chase a missing W-9 before the filing deadline.
Where Usual fits
Usual is built for the collection side of this split: recurring requests per client and tax year, item-level status, reminder schedules with escalation, and a client portal for uploads. Full-text search with OCR and routing files into tax software are not the focus, so a firm that needs them should check them directly in a trial, and keep a repository for those jobs if it has to.
