Soraban

Soraban sits between client document collection and the tax software, which is where preparers lose hours every busy season. It is built for US returns and the US tax stack, and should be judged on how well it serves that market.

What it does well. The workflow is complete: intake, document sorting, extraction, workpapers, review, e-signature and payment in one flow. It pushes extracted data into UltraTax, Lacerte, Drake and CCH Axcess, the packages US firms already use, so it adds to the stack instead of replacing it. Security claims are specific, with SOC 2 Type II, annual third-party audits and an IRS 8879 e-signature flow the vendor says meets NIST IAL2. Traction is real: named firm testimonials, a claim of more than 350 firms, Y Combinator backing and a reported Series A led by Altos Ventures.

Where it falls short. Pricing is not published and there is no free trial; firms start with a demo and onboarding that the vendor says takes weeks. Accuracy figures are inconsistent on the page, quoting 99.9 to 100 percent in one place and 99 percent in another, and the on-page counters showed placeholders, so insist on testing your own documents. ProConnect support is listed as coming soon, which matters if that is your engine. Funding totals reported by third parties conflict, so treat them with caution.

Best for. US tax practices preparing individual and small business returns in UltraTax, Lacerte, Drake or CCH Axcess that want less manual data entry. In a trial, run twenty real client packs, measure corrections, and check what happens when a document is misclassified.

Verdict. A focused, credible workflow tool for US preparers, strongest where document volume is the bottleneck. Compare SurePrep for larger firms and Black Ore Tax Autopilot for per-return automation. Also ask how data is deleted after a client leaves, who reviews the AI flags before a return is finalised, and what a mid-season price change would look like, since busy season is the worst time to renegotiate.
