B2B Fintech

SMB financial workflow SaaS for bookkeepers, small accounting firms, and finance ops at growth-stage companies. Mordor embedded finance: $125.95B (2025) → $454.48B (2031), 23.84% CAGR. Solo-accessible slice: SMB financial workflow tools at the bookkeeper/accountant layer — month-end close checklists ($49-99/mo, QBO/Xero integration), vertical cash flow forecasting ($49-79/mo, Plaid + invoice data), and bank fee/subscription audits ($29-49/mo). FX rails, embedded lending, and cross-border payments require bank partnerships and compliance infra — not solo-accessible.

Unsolved problems

3 problems · 6 ideas

Problem 01

Solo bookkeepers and small accounting firms (1–5 staff) doing month-end close for 5–20 clients have no structured close checklist — they rely on memory and email threads to track which accounts are reconciled, which journal entries are posted, and what's still outstanding, leading to missed items and slow close.

CloseCheck

Month-end close checklist and variance tool for bookkeepers: create a reusable close checklist per client (reconcile checking, post payroll JE, review AP aging, etc.), track completion status for each period, flag account variances vs. prior month automatically via QBO/Xero API, and generate a close summary for client delivery.

Revenue$49/mo for up to 5 clients; $99/mo unlimited clients

BookkeeperDesk

Client workflow manager for solo bookkeepers: track open tasks by client and deadline, standardize monthly deliverables per client engagement, and generate a status dashboard showing which clients are behind on data delivery — replacing the 'post-it notes and memory' system.

Revenue$49/mo per bookkeeper

Problem 02

Agency owners and freelancers with irregular income (retainer + project-based) can't use horizontal cash flow tools (Float, Pulse) because those tools assume recurring revenue — they need a forecasting tool that understands retainer income, project milestones, and late-paying clients.

AgencyFlow

Cash flow forecasting tool for agencies and freelancers: connect bank accounts via Plaid and invoicing tools (FreshBooks, Harvest, QuickBooks) → model retainer income as recurring, project milestones as expected dates, and outstanding invoices as probability-weighted inflows → show 90-day cash position with 'what-if' scenarios for new project wins or client losses.

Revenue$49/mo per agency owner; annual plan at $399/yr

FreelanceFloat

Cash flow planner for freelancers and solopreneurs: connect bank + invoice data, track outstanding invoices by expected payment date, model estimated vs. actual income for the next 3 months, and get an alert when projected cash position drops below your survival threshold — replacing the 'mental math every Sunday' approach.

Revenue$29/mo per freelancer; free tier up to 10 invoices

Problem 03

SMB owners and finance ops managers don't know how much they're spending on SaaS subscriptions or bank fees — overpaying on zombie subscriptions, merchant processing tiers, and bank wire fees that could be negotiated or eliminated.

SpendAudit

SaaS and bank fee auditor for SMBs: connect bank accounts via Plaid (read-only), automatically categorize and identify recurring SaaS subscriptions, flag bank fees that appear above standard rates for the account tier, and generate a 'money left on the table' report with negotiation scripts for each overcharge.

Revenue$29/mo subscription; one-time $99 audit report for non-subscribers

SubScan

Recurring expense monitor for small businesses: identify all active subscriptions and recurring charges from bank/card transactions, categorize by department and owner, flag subscriptions with no usage evidence (unused licenses), and surface duplicate tools — with a savings estimate for each cut.

Revenue$19/mo for SMBs with up to $500K/yr in transactions
