CentSense vs Bonsai (2026): Which Is Better for Freelancers?

Published: May 11, 2026 · Reading time: 8 min

TL;DR: CentSense ($5/mo) is a focused Schedule C expense tracker with AI receipt scanning, mileage tracking, and per-client projects. Bonsai ($25–$39/mo) is a full freelance OS — proposals, contracts, invoicing, time tracking, plus a lighter expense module. CentSense wins on price (≈80% less per year), Schedule C output, and receipt OCR. Bonsai wins on workflow consolidation if you also need contracts and client billing in one app. Many freelancers run CentSense + a free invoicing tool and end up with stronger tax output for far less money.

If you're shopping for a freelance tool, you've probably looked at both CentSense and Bonsai. They're both designed for solo, 1099, and small-business freelancers — but they optimize for very different parts of the workflow.

This comparison helps you pick the right tool for your actual day-to-day, with honest trade-offs.

Quick Comparison

Where Each App Wins

CentSense wins for tax-time output and price

If your biggest pain point is lost deductions and a chaotic Schedule C at year end, CentSense is the focused tool. Every receipt — AI-scanned or manually added — gets auto-mapped to a Schedule C line (Line 8 advertising, Line 22 supplies, Line 24b meals at 50%, Line 30 home office, and so on). The year-end export is grouped by line number with totals, so your CPA's reconciliation work drops from hours to minutes.

It's also cheaper. Solo is $5/month — roughly $60/year. Bonsai's entry plan is $25/month — roughly $300/year. Over five years, the difference is $1,200, which for many solo freelancers is more than they pay their CPA annually.

Bonsai wins for workflow consolidation

If you don't have a dedicated invoicing tool and you want one app for proposals, contracts, invoicing, time tracking, and a basic expense ledger, Bonsai is the consolidator. Its template library covers freelance writing contracts, design SOWs, photography releases, and consulting MSAs. Time tracking can roll directly into invoices. For freelancers who hate stitching together five SaaS tools, that's real value.

The trade-off is depth on the expense side: Bonsai's expense module is functional but secondary, with no AI vision receipt scanning and less granular Schedule C mapping.

Side-by-Side: Real Workflows

Workflow 1: Freelance copywriter with three retainer clients

Edge: Bonsai if you value the invoicing + contracts piece. CentSense if you already invoice elsewhere.

Workflow 2: Multi-client freelance designer at $90k/year

Edge: Bonsai for the proposal-to-cash piece. CentSense for the tax-output piece. Many designers run both.

Workflow 3: Side-hustle freelance writer at $18k/year

Edge: CentSense, decisively. At $18k/year revenue, the $240 annual savings is meaningful and the simpler workflow lowers monthly friction.

Pricing Breakdown (2026)

The CentSense Solo plan is $240/year cheaper than Bonsai Starter — enough margin to subscribe to a dedicated invoicing tool (Stripe Invoicing is free, FreshBooks Lite is $102/year) and still come out ahead.

The Schedule C Question

This is the single biggest difference between the two apps.

CentSense was designed from the ground up around Schedule C. Every category in the app maps to a specific IRS line:

• Line 8 → Advertising
• Line 9 → Car and truck expenses (mileage at $0.725/mile)
• Line 11 → Contract labor
• Line 13 → Depreciation and §179
• Line 15 → Insurance
• Line 17 → Legal and professional services
• Line 22 → Supplies
• Line 24a → Travel
• Line 24b → Meals (50%)
• Line 25 → Utilities (phone, internet)
• Line 30 → Home office

The year-end export groups every transaction by line number, sums the totals, and produces a one-page summary your CPA can transcribe directly into Form 1040 Schedule C. See Schedule C Lines hub for the full line-by-line breakdown.

Bonsai's expense module is functional and exports clean CSVs, but Schedule C alignment is a manual mapping step at tax time.

When to Pick Bonsai

Pick Bonsai if:

• You need proposals, contracts, and e-signature in your workflow today
• You don't have invoicing handled (no Stripe, no Square, no FreshBooks)
• You bill by the hour and need time tracking that rolls into invoices
• You want a single tool and can afford $300–$468/year
• Expense tracking depth is secondary to client-facing workflows

When to Pick CentSense

Pick CentSense if:

• Your top pain point is lost receipts and chaotic Schedule C at year end
• You already invoice through Stripe, Square, PayPal, or FreshBooks Lite
• You want AI vision-based receipt scanning (not just manual entry)
• You want mileage tracking at the 2026 IRS rate baked in
• You want to spend $60/year instead of $300+
• You file your own return or want to cut your CPA's bill by handing over a clean export

The "Run Both" Stack

A surprising number of established freelancers run CentSense + a dedicated invoicing tool:

Even the most expensive CentSense + FreshBooks stack at $162/year is $138/year cheaper than Bonsai Starter — and you get stronger Schedule C output.

Common Questions

Does CentSense replace a CPA? No. Both tools improve recordkeeping; neither substitutes for personalized tax advice. CentSense reduces the hours your CPA bills.

Can I migrate from Bonsai to CentSense? Yes — export your Bonsai expenses to CSV, then import into CentSense. The Schedule C line mapping happens automatically on import.

Does Bonsai have mileage tracking? Bonsai supports manual mileage entry but lacks the automatic GPS-based trip detection and IRS-rate calculation that CentSense includes natively.
