Client Question Triage

A shared inbox built for small tax offices that logs client questions from text, WhatsApp and email, tags each one to a return, and shows who still owes an answer before filing day.

Read the full idea

Who pays
Owner of a small tax office with 2 to 10 preparers
The problem
Clients send questions by text, WhatsApp and email all season, and the office loses track of who answered what. The owner cannot see which returns still have an open question before the filing deadline.
The gap
General shared inbox tools like Front and Missive are not built around a tax return as the unit of work. They do not tag a message to a specific return, do not show open questions per return, and do not tie the queue to a filing deadline.
Already out there
  • Front front.com

    Aggregates team messaging into one inbox with assignment and reporting. Not built around tax returns or filing deadlines.

  • Missive happyfox.com

    Shared inbox plus team chat and collaborative drafts. No concept of a return or a filing deadline.

  • InBox Zero getinboxzero.com

    AI sorting and smart replies for shared inboxes. Generic, not tax specific.

People asking for it
The big assumption
Small tax offices will move client questions out of their personal phones and email into a shared tool during their busiest weeks.
Test it this week
Interview five independent preparers and ask them to walk through last season's client questions from their phone and inbox. Count how many were lost or double answered.

Prior Year Rescue

A referral service and simple intake form that lets an independent preparer hand off messy back-tax clients to a vetted preparer network for a flat fee, with no client poaching.

Read the full idea

Who pays
Independent tax preparer who refers the client
The problem
Preparers get clients with missing years, IRS notices and unfiled returns, and those jobs eat time they do not have in season. They turn the client away with nowhere to send them.
The gap
The results show free volunteer help (AARP Tax-Aide), big chains (H&R Block), and expat specialists (Greenback), but no neutral referral network where one independent preparer hands a messy back-tax client to another for a flat fee with a no-poaching rule.
Already out there
People asking for it
The big assumption
Preparers will trust a network enough to hand over a client and pay a flat referral fee without losing the client.
Test it this week
Ask ten independent preparers how many messy back-tax clients they turned away last season, and whether they would pay a flat fee to send those clients to a vetted preparer.

Client Document Chase

A simple tracker that shows which clients still owe documents, what is missing, and who has been reminded, so the office stops chasing the same people by hand.

Read the full idea

Who pays
Owner of a small tax office with 2 to 10 preparers
The problem
Every season the office chases the same clients for missing documents by text and email, and nobody knows who was already reminded. Returns sit unfinished while the deadline gets closer.
The gap
The results show general shared inbox tools and full tax software suites, but no lightweight tracker built for a small office that lists missing documents per client and the reminder history.
Already out there
People asking for it
The big assumption
Small offices will keep a separate document tracker updated when their tax software already holds client records.
Test it this week
Ask five preparers to list, from memory, which clients still owe documents today. If they cannot, test whether they would update a shared list daily.
