Who this stack is for
1–5 person accounting or bookkeeping practice. You serve small businesses ($0-$50M revenue) and the owners delegate their books entirely to you. You have:
- At least 10 active monthly bookkeeping clients or 50+ tax-season clients.
- A physical office, or a clear work-from-home setup with dedicated infrastructure.
- Compliance obligations (client data retention, IRS requirements, state PTR rules).
If you’re a solo bookkeeper with fewer than 5 clients, skip the practice management software — you’re not there yet. A spreadsheet and Google Calendar is enough.
If you’re a mid-sized firm (10+ staff) — the tools still apply but you’ll likely want the Enterprise tier of everything. The shape of the stack doesn’t change.
The essential stack (Day 1)
Client accounting: QuickBooks Online Accountant (ProAdvisor)
This isn’t a choice. QuickBooks Online is what US small businesses use; if you want to serve them, you need QuickBooks Online Accountant (ProAdvisor program) access — it’s free if you become certified. The alternative (Xero Partner) is the right pick if 30%+ of your clients are outside the US or if you’ve made a strategic decision to differentiate on Xero expertise.
Practice management: Karbon or Canopy
The bookkeeping-and-nothing-else tools (QBO, Xero) don’t handle YOUR workflow — client onboarding, task templates across clients, time tracking, billing your time, collection. Karbon and Canopy both do. Pick Karbon if your team is ≤5 and you want better UX; Canopy if you also need client portal + document management baked in.
Password manager: 1Password Business
Client login vaults are a compliance obligation, not a nice-to-have. You’ll have hundreds of client QBO logins, bank logins, payroll logins. 1Password Business’s audit logs and shared vault structure are what your E&O insurance auditor wants to see.
Secure document exchange: ShareFile (or equivalent)
Clients email tax documents. This is a bad idea. ShareFile (or Citrix Files, or Clio Docs if you’re also a law firm) encrypts document transfer, tracks who downloaded what, and gives clients a portal rather than an email chain. Don’t cheap out here — the audit log alone pays for it.
Internal wiki: Notion
Client-specific procedures (how to close their books), firm-wide SOPs (onboarding, tax season checklists), training materials for new staff — all belong in Notion. The wiki you build in year one becomes the firm’s moat.
Add these at 10+ seats or $1M revenue
- Power BI or Tableau — once you’re advising clients on numbers (not just compiling them), you need visualization beyond QBO dashboards.
- Gusto Partner — payroll for clients. If 20%+ of your clients need payroll, become a Gusto or ADP partner.
- Slack Connect — for select clients where email is too slow. Not all clients; they’ll abuse it.
Skip these (but everyone recommends them)
- Separate time-tracking tool (Harvest, Toggl) — Karbon and Canopy both have time tracking built in. Don’t double up.
- Dedicated CRM — Karbon has pipeline management. A dedicated CRM layer isn’t needed at this scale.
- Virtual phone system for each partner — one shared number with an IVR + routing is fine. Ruby Receptionists if you want a human answer.
Compliance notes
- Client data retention: match your state’s PTR (practitioner record keeping) rule — usually 3-7 years. Build retention into your document management.
- IRS Publication 1075 (if you handle federal returns): your systems need to meet their security requirements. ShareFile, QBOA, and 1Password Business all have SOC 2 Type II.
- State privacy acts (CCPA, SHIELD, etc.): if you serve clients in those states, your PII handling must comply.
Total monthly cost
At list prices for a 5-seat firm:
- QBOA: Free (with certification)
- Karbon: $59/user/mo × 5 = $295/mo
- ShareFile Premium: $100/mo
- 1Password Business: $40/mo
- Notion Business: $90/mo ($18/user × 5)
- Total: $525/mo
Add another $200-400/mo for incidentals (training, tax research tools, e-sign volume). Call it $800/mo all-in for a 5-person firm — meaningfully less than one billable hour per week.
FAQ
Do I need QBO if most of my clients use Xero?
No. Pick one primary platform and specialize. Most US practices pick QBO. If you picked Xero strategically, lean in — the Xero Partner program has real marketing support in markets where Xero is strong.
Can I use Google Drive instead of ShareFile?
Technically yes. Practically, the audit-log and per-file download tracking that ShareFile provides is what satisfies compliance reviews. Google Drive Business has some of this but the experience is weaker. Save money here only if you’re solo and small.
What about tax prep software?
Depends on your tax mix. For 1040-heavy practices, UltraTax or Lacerte. For business returns, ProConnect or Drake. This is a big decision — we’d cover it in a separate tax-software-for-small-practices guide, not in a SaaS stack page.
