TL;DR

Plutio and COLO overlap heavily on scope; the decision is workflow speed, portal polish, and pricing shape.
Free-forever Solo plan on COLO; Plutio's cheapest plan is paid and gates users, contacts, and projects.
Portal on your own domain. COLO's client portal sits on yourbusiness.com; Plutio's is on a vendor-hosted URL.
Flat workspace pricing on Pro/Grow — no per-collaborator multiplier.

Why freelancers switch from Plutio to COLO

Plutio is the closest direct peer to COLO by feature scope. Proposals, contracts, projects, time, and invoicing all live inside one product, and the community is loyal. If your business is structured — repeat clients, defined services, recurring invoices — Plutio does its job.

The switching driver is almost always one of three things: (1) workflow speed — clients notice the difference between a portal that feels fast on mobile and one that feels a step slower; (2) portal polish — brand-on-your-domain matters more the higher your project value; (3) pricing shape — Plutio caps users, contacts, and projects on its lower tiers, and going up a tier to lift those caps is not always the same as adding the feature you actually want. COLO reverses each: modern mobile-first surface, client portal on your custom domain, and workspace-flat pricing with a free Solo below it.

Pricing comparison

Verify current numbers with each vendor before you decide.

Plutio — three tiers, priced by users and features.

Solo: single user, capped contacts and projects.
Studio: adds users and lifts caps; targeted at small agencies.
Agency: full users, full caps, white-label options.

COLO — free Solo, then flat workspace.

Solo: free-forever for one operator, no card, no trial timer.
Pro: flat workspace with multiple users, all core features.
Grow: flat workspace with expanded seats, storage, and automation.

Verify with each vendor before you decide.

The structural point: Plutio prices around users and caps; COLO prices around workspaces. If your team grows, the Plutio curve rises step-wise through tiers; COLO stays flat inside a plan.

When to pick COLO over Plutio

Free forever for a solo operator. No card, no trial timer.
You value a portal on your own domain. Client portal on yourbusiness.com reads as your brand, not Plutio's.
You want fewer caps on contacts and projects. COLO's Grow scales without contact caps that force tier upgrades.
Mobile-first daily project work. Replying, approving, and invoicing on the go without a UI that was designed for desktop first.
Workspace-flat pricing as you add teammates. No per-collaborator tax.

When to STAY with Plutio

You are deep into Plutio's flexible builder. If your proposals and contracts rely on Plutio's block-level builder patterns you have refined, migration effort is real.
You already use Plutio's white-label features on Agency. If your business runs on that specific white-label setup, only switch if a hard requirement above forces it.
Your team already knows Plutio. Re-training a team is a hidden cost. Weigh it honestly.

Migration guide — moving from Plutio to COLO

Export contacts, projects, invoices as CSV from the relevant Plutio screens.
Download signed contracts and key proposals as PDFs from the documents library.
Open a COLO workspace and import the CSV files; attach PDFs to matching client records.
Recreate your monthly-use templates — two or three proposals, one or two contracts, one intake form.
Reconnect your payment processor and send one live low-value invoice as a smoke test. See the getting paid guide.
Run both tools in parallel for two to four weeks while retainer cycles and in-flight invoices clear.
Update client-facing links — portal URL, payment links on outstanding invoices — to COLO.

Common gotchas: Plutio's block-level proposal builder does not export as portable HTML — you will rebuild the visual layout rather than paste it in. Recurring subscriptions with card-on-file need re-authorisation.
