If you search for retainer management software, you'll find a lot of the same tools listed over and over. Scoro. Accelo. Teamwork. Productive.
They're all solid tools. They're also built for agencies with 10-50 person teams, project managers, account directors, and budgets to match.
If you're a solo freelancer or a small consultancy billing two or three retainer clients a month, these tools are overkill. You don't need automated workflows, resource forecasting, or AI-driven project timelines. You need to track your hours, show your client where they stand, and send the invoice.
This is an honest comparison of the tools available in 2026 — what they're good for, what they cost, and who they're actually built for.
What to look for in a retainer management tool
Before getting into the list, here's what actually matters if you're a freelancer managing retainers:
Client visibility. Can your client see their hours in real time, or do they only find out when the invoice arrives? This single feature prevents more invoice disputes than anything else. Read more about what a client portal actually does and why it matters.
Time tracking built in. Switching between a time tracker and a billing tool adds friction and introduces errors. The best tools do both.
Simple invoicing. You shouldn't need an accountant to generate a monthly invoice. It should be automatic, or close to it. See our guide on best freelance invoicing practices for what good invoicing looks like.
Price that makes sense. If you're billing $2,000/month in retainers, paying $150/month for billing software is a bad deal. Make sure you've also read how to price a retainer so you know what you should be billing in the first place.
With that in mind — here's the list.
1. Retallio — Best for solo freelancers who want client transparency

Price: Free for 1 client, $19/month for up to 10 clients
Built for: Solo freelancers and small consultancies on monthly retainers
Retallio is the only tool on this list built specifically around client transparency. When you add a retainer client, they automatically get a live portal where they can see your hours, your work logs, and their invoice building in real time throughout the month.
The idea is simple: if your client can watch the invoice grow, there's nothing to dispute when it arrives. The invoice conversation stops happening not because you explained yourself better, but because there's nothing left to explain.
What it does well:
- Live client portal that updates every time you log time
- Built-in timer tied directly to each client
- Automatic overage calculation when clients go over their included hours
- Clean, minimal interface that takes minutes to set up
What it doesn't do:
- No project management features
- No team collaboration
- Not built for agencies with multiple staff
Bottom line: If you're a solo freelancer tired of explaining your invoices every month, Retallio is built for exactly that problem. Nothing more, nothing less.
2. Retainable — Good client portal, but limited time tracking

Price: Starts around $29/month
Built for: Freelancers and small agencies who want client-facing portals
Retainable is the closest thing to Retallio in terms of concept — it gives clients a portal to view retainer usage. The interface is clean and the client-facing experience is solid.
Where it falls short is time tracking. Retainable focuses more on task management and deliverable tracking than on raw hour logging. If your retainer is time-based rather than deliverable-based, you'll likely still need a separate time tracker alongside it.
What it does well:
- Clean client-facing portal
- Good for task and deliverable tracking
- Collaboration features
What it doesn't do:
- Time tracking is limited
- Invoice generation requires manual work
- Pricing adds up quickly
3. Harvest — Best for straightforward time tracking and invoicing

Price: Free for 1 seat and 2 projects, $12/month per seat after that
Built for: Freelancers and small teams who need reliable time tracking with invoicing
Harvest has been around since 2006 and it shows — in a good way. It's reliable, well-designed, and does exactly what it says. You track time, you invoice clients, you get paid.
The gap with Harvest is the client experience. Clients don't get a portal. They get an invoice at the end of the month. There's no live view of hours, no way for them to check in mid-month. For clients who are budget-conscious or who've been burned by surprise invoices before, this can be a problem. This is exactly why clients question invoices — they have no visibility until the end of the month.
What it does well:
- Clean, fast time tracking
- Solid invoicing with Stripe integration
- Good reporting and project budgets
- Integrates with almost everything
What it doesn't do:
- No client-facing portal
- No live hour visibility for clients
- Can feel dated compared to newer tools
4. Toggl Track — Best pure time tracker, but you'll need other tools

Price: Free for basic, $9/month per user for Pro
Built for: Anyone who needs reliable time tracking
Toggl is the most popular time tracker in the freelance world for a reason. It's fast, it works on everything, and the free tier is genuinely useful. If you just need to track time accurately, Toggl is hard to beat.
The problem is it stops there. No invoicing, no client portal, no retainer management. You'll need to pair it with something else to handle billing — typically FreshBooks, Wave, or a spreadsheet — and that's where the friction and errors creep in. For a full breakdown of better options, see 5 best Toggl alternatives for freelancers.
What it does well:
- The best pure time tracking experience available
- Fast timer, works everywhere
- Good reports and team features
- Free tier covers most freelancer needs
What it doesn't do:
- No invoicing
- No client portal
- No retainer-specific features
- Requires extra tools to complete the billing workflow
5. Scoro — Best for agencies who need everything in one place

Price: Starts at $26/user/month, minimum 5 users
Built for: Agencies and professional services teams
Scoro is genuinely impressive software. Real-time retainer dashboards, budget tracking, resource management, CRM, invoicing — it does everything. If you're running an agency with multiple team members and complex client relationships, it's worth looking at.
For solo freelancers, it's complete overkill. The minimum is 5 users, so you're paying at least $130/month before you've done anything. The interface takes time to learn. The feature set is designed for teams, not individuals.
What it does well:
- Comprehensive retainer management for agencies
- Real-time dashboards and budget tracking
- Excellent reporting and insights
What it doesn't do:
- Not built for solo freelancers
- Expensive (minimum 5 users)
- Complex to set up and maintain
6. ManyRequests — Best for productised services and client portals

Price: Starts at $99/month
Built for: Agencies offering productised or subscription-based services
ManyRequests is popular with design agencies and content studios who offer subscription-based services. It has a polished client portal where clients can submit requests, track status, and communicate.
It's less suited to time-based retainers. If you're billing by the hour, ManyRequests is more workflow than time tracking. The price is also significant — $99/month is a lot if you're a solo freelancer.
What it does well:
- Great client portal experience
- Good for request-based or deliverable-based work
- Professional white-label options
What it doesn't do:
- Not built for hourly retainers
- Expensive for solo freelancers
- Overkill if you just need time tracking and invoicing
7. Bonsai — Best all-in-one for freelancers who want contracts too

Price: Starts at $21/month
Built for: Freelancers who want contracts, proposals, time tracking, and invoicing in one place
Bonsai is the most well-rounded all-in-one tool for freelancers. It handles contracts, proposals, time tracking, invoicing, and expenses. If you're starting out and want one tool to handle everything, Bonsai is a strong option.
The retainer-specific features are decent but not deep. There's no live client portal. Clients get invoices, not visibility. For freelancers who have recurring issues with invoice disputes, Bonsai doesn't solve the root problem. If contracts are important to you, also read our retainer agreement template which covers what you actually need.
What it does well:
- Strong contracts and proposals
- Good all-in-one value
- Reasonable price for what you get
What it doesn't do:
- No live client portal
- Retainer features are basic
- Time tracking is not as fast as dedicated trackers
The honest summary
| Tool | Client Portal | Time Tracking | Invoicing | Best For | Price |
|---|---|---|---|---|---|
| Retallio | Live, real-time | Built in | Automatic | Solo freelancers | $19/mo |
| Retainable | Yes | Limited | Manual | Deliverable retainers | $29/mo |
| Harvest | No | Excellent | Built in | Time tracking + billing | $12/mo |
| Toggl | No | Best in class | None | Pure time tracking | Free/$9 |
| Scoro | Yes | Yes | Yes | Agencies (5+ users) | $130+/mo |
| ManyRequests | Yes | Limited | Yes | Subscription agencies | $99/mo |
| Bonsai | No | Good | Yes | All-in-one freelance | $21/mo |
Which one should you use?
If you're a solo freelancer billing two or three retainer clients and you're tired of the invoice conversation every month — Retallio is built for that exact problem. Start with the free plan, add your first client, and see what the portal looks like from their side.
If you need reliable time tracking and you handle invoicing separately — Toggl is still the best pure tracker available.
If you want an all-in-one tool and client transparency isn't your main concern — Bonsai gives you the most for the price.
If you're running an agency with a team — Scoro or Accelo are worth evaluating seriously.
The worst thing you can do is pay for a complex agency tool when all you need is something simple that keeps your clients informed. Start by understanding retainer vs project billing — knowing which model fits your business makes picking the right tool much easier.
