TL;DR

Bonsai is polished at "one operator, one book of clients"; COLO is built for that plus the day you add a sub-contractor, a VA, or a partner.
Free-forever Solo plan on COLO; Bonsai starts paid and its higher tiers add per-user cost.
Portal on your own domain. COLO's client portal lives on yourbusiness.com.
Deeper project management — tasks, milestones, deliverables the client can see and approve — instead of a to-do list for you alone.

Why freelancers switch from Bonsai to COLO

Bonsai has earned its user base among solo designers, writers, and developers with a genuinely clean interface and a coherent product feel. Contracts and proposals sit in the same head-space as invoicing and time tracking; a solo freelancer with a steady book of clients can run a whole year of work in Bonsai without ever wanting for a feature that is not there. That is a hard thing to build and Bonsai does it well.

The friction shows up at the seams of "solo". The moment you bring in a sub-contractor to help with a project, the tool starts asking for another paid seat rather than giving you a way to keep them in the loop as a collaborator. The moment a client expects to log into a portal that carries your studio name, you notice how much of the portal's chrome is Bonsai's rather than yours. And the moment the retainer client's expectations creep from "invoice me monthly" to "let me see the project plan and approve deliverables," you realise Bonsai's project surface is fine for you and thin for them. COLO gets you the same clean solo experience with those three ceilings raised: collaboration without a per-seat toll, a portal on your own domain, and real client-visible milestones and tasks.

Pricing comparison

Both vendors update their pricing pages; verify current numbers before you decide.

Bonsai — tiered plans, single user by default.

Starter: entry plan for a solo freelancer with core proposals, contracts, and invoicing.
Professional: adds client CRM, forms, and workflows; still targeted at one operator.
Business: unlocks additional users, subaccounts, and more — priced per additional user.

COLO — free Solo, then flat workspace.

Solo: free-forever for one operator, no card, no trial timer.
Pro: flat workspace with multiple users, proposals, contracts, projects, invoicing, portal.
Grow: flat workspace with expanded seats, storage, and automation.

Verify with each vendor. SaaS pricing changes; treat this as the shape, not the number.

If you are a genuine single-operator on a stable book, Bonsai's Starter is competitive with COLO's Solo — but Solo is free. Once you need a second user, the two curves diverge: Bonsai's per-user Business tier compounds with team size; COLO's Pro/Grow is workspace-flat.

When to pick COLO over Bonsai

You want a free-forever solo tier. No card, no trial timer, no upgrade gate on the proposal-to-invoice path.
You collaborate with sub-contractors. COLO's workspace-flat pricing on Pro/Grow means adding a designer or developer to a project is not a per-seat billing event.
You want a portal on your own domain. Client portal on yourbusiness.com, not on a vendor's hosted URL.
Your projects have deliverables the client should approve. Real project management with milestones and tasks the client can see beats a private to-do list.
You expect to grow into a small studio. COLO's growth path is on the same platform; Bonsai's growth path involves paying per user or moving.

When to STAY with Bonsai

You are firmly single-operator and expect to stay that way. Bonsai's Starter/Professional plan handles solo work well, and re-platforming to save a modest amount is not worth the disruption.
You use Bonsai's tax and bookkeeping helpers heavily. If year-end reporting inside Bonsai has become the way you close your books, weigh that carefully against a switch.
Your clients love the Bonsai UI. Client-facing polish is real and worth respecting. Migrate only if a hard requirement above forces it.

Migration guide — moving from Bonsai to COLO

Export clients, projects, and invoice history from Bonsai as CSV; download signed contracts and sent proposals as PDFs from the documents library.
Open a COLO workspace and import the CSVs; attach contract PDFs to the matching client records.
Recreate your most-used templates — the two or three proposals, one or two contracts, and one intake form you use monthly.
Reconnect your payment processor (Stripe, PayPal, or local) and send one live low-value invoice to test the flow. See the getting paid guide.
Run both tools in parallel for two to four weeks while retainer cycles bill out and in-flight invoices clear.
Update payment links on outstanding invoices to the COLO portal; retain the Bonsai account read-only until the parallel window closes.
Cancel Bonsai after export archive. Keep a full CSV/PDF archive on your side before you cancel.

Common gotchas: Bonsai time-tracking history exports as CSV but line-item detail formatting varies — check the first import batch by hand. Recurring subscriptions with card-on-file need re-authorisation in the new processor.

FAQ

Is there a free plan for solo operators? Yes — COLO ships a free-forever Solo plan. Bonsai's entry tier is paid.

Does COLO replace Bonsai end-to-end? For most solo freelancers, yes. Proposals, contracts, projects, invoicing, portal, and chat are native. The one caveat is heavy tax/bookkeeping features on Bonsai's top tier — many operators keep QuickBooks for that.

How long does the migration take? Most operators complete the data import in an afternoon and run both tools in parallel for two to four weeks.

Will my Bonsai contracts remain valid after switching? Yes — e-signed contracts remain legally valid regardless of platform. Attach PDFs to the client record in COLO.

Can I add a sub-contractor without extra cost? On COLO's paid workspace-flat plans, adding a collaborator does not multiply the bill. On Bonsai's Business tier it does — verify current per-user rates.

Can I keep Bonsai's tax features? If tax features are the reason you use Bonsai, pair COLO for the proposal-to-invoice flow with Bonsai (or QuickBooks / FreshBooks) for the accounting layer.

Does COLO have time tracking? Yes — native, per-project, with billable rates rolled into invoices.

Can I white-label the portal? Yes — the COLO client portal lives on your own custom domain.

Is there an import script for Bonsai data? Bonsai exports CSV; COLO imports CSV directly. No custom script is required for the standard fields (clients, projects, invoices).

What if I need to move back? Full CSV export of clients, projects, and invoices is available at any time.
