Teamwork vs. HourTab for retainer client hours visibility

July 12, 2026 · ~13 min read

Teamwork.com is one of the few project management platforms built specifically for client-service agencies. Where tools like Asana, Monday.com, ClickUp, and Jira are designed for internal team productivity, Teamwork has always had a client-work orientation: client accounts, project-level billing, time tracking built into task views, client portals, and — notably — native retainer billing that lets agencies track monthly hours budgets per client.

That native retainer billing is a genuine differentiator. If you are comparing Teamwork to Jira or Asana for a retainer-heavy agency, Teamwork’s retainer features are a meaningful advantage. The agency can configure a monthly hours budget per client, log time against that budget, generate retainer utilization reports, and see at a glance which clients are approaching their cap and which have hours remaining.

But if the question is “can my retainer clients see their own hours balance without logging in somewhere?” — the answer in Teamwork is no. Teamwork’s retainer tracking is an internal agency view. The client-facing side requires a Teamwork account and a login, and what clients see in Teamwork’s portal is project activity, not a live hours-remaining balance they can check in ten seconds. This post explains that gap clearly and shows how Teamwork and HourTab work together in a complete retainer billing workflow.

What Teamwork actually does for retainer agencies

Teamwork’s feature set is built around the agency workflow: client accounts at the top level, multiple projects per client, tasks and milestones within projects, team member time logging against tasks, billing rates per user or per project, and invoicing tools that pull from logged time. For agencies running ten to one hundred retainer clients, this is a comprehensive operational platform.

The retainer feature (available on Growth plan and above) allows agencies to create retainer records linked to a client. Each retainer record has a monthly hours budget, a start date, and a renewal period. As team members log time in Teamwork, hours are counted against the retainer budget. The agency account manager can see a retainer overview showing hours consumed vs. budget remaining, pull a retainer report for billing, and get alerts when specific clients approach their cap.

This is substantially more useful than what agencies get from generic project management tools. An agency trying to track retainer budgets in Basecamp is maintaining that tracking manually, in a spreadsheet or a pinned document, with no automatic connection to time logs. Teamwork connects the time logging and the retainer budget natively, which eliminates the manual reconciliation step and reduces billing errors.

Teamwork also includes time tracking built into tasks: team members can log hours directly against a Teamwork task, or use the built-in timer to log real-time. Time logs can be marked as billable or non-billable, assigned to billing rates, and filtered by date range for reporting. The time tracking layer is more integrated into the project workflow than external time trackers like Toggl or Harvest, which require manual linking between project activity and time entries.

The gap: Teamwork’s retainer billing is internal, not client-facing

Every Teamwork retainer feature described above is an internal view — available to the agency’s account managers, project managers, and billing team. The information about how many hours a client has consumed and how many remain is inside Teamwork, accessible only to users who have Teamwork accounts with the appropriate permissions.

Teamwork does have a client portal that gives clients a view into their projects. With the right permissions configured by the agency, clients can log into the client portal and see:

• Task lists for their projects, with status and assignees
• Project progress and milestones
• Files and documents shared by the agency
• Project updates and announcements
• Team member availability (if enabled)

What clients cannot see in Teamwork’s client portal: their retainer hours balance. The portal shows project activity, not the retainer billing tracking. A client who logs in and navigates to their project view will see what tasks are in progress, what was recently completed, and what’s coming up. They will not see “18 of 30 hours used this month · 12 hours remain · resets September 1” because that information lives in the retainer billing section of Teamwork, which is an internal agency view, not a client portal view.

Some agencies work around this by granting clients access to specific time reports within Teamwork — essentially giving the client enough Teamwork access to generate their own utilization report. This requires the client to have a Teamwork account, know how to filter a time report by client and date range, interpret the report correctly, and convert the raw hours data into the “hours remaining” number they actually want. For most retainer clients — whose primary interest is knowing how many hours they have left, not how to use Teamwork’s reporting interface — this is too much friction.

The account requirement: what Teamwork client access actually requires

Whether the client is using Teamwork’s standard client portal or a specially configured time report view, they need a Teamwork account. Creating a Teamwork account requires an email address, a password, and email verification. For clients who already use Teamwork (they have their own Teamwork subscription for their internal work), this is no barrier. For clients who don’t — which describes most small business and startup retainer clients — it is one more SaaS account in an already cluttered account landscape.

The account friction matters at the moment of peak relevance. The client emails their account manager: “Can you let me know where we stand on hours? We want to add a new feature but don’t want to go over.” The account manager points them to the Teamwork client portal. The client remembers they created a Teamwork login six months ago but can’t remember the password. They reset it, log in, navigate through the Teamwork interface to find the relevant project, realize they can’t see the retainer balance from the project view, give up, and email the account manager again.

A client checking a HourTab URL has a different experience: they click the bookmark, the page loads showing their current balance and work log, they answer their own question in under ten seconds, and the email to the account manager doesn’t get sent. The difference between a login and a URL is the difference between a question the client answers themselves and a question that becomes an admin task for the account manager.

What clients actually need vs. what Teamwork provides

The question retainer clients ask is simple: “How many hours do I have left this month?” They don’t want a project management platform. They don’t want a task board. They don’t want to learn Teamwork’s reporting interface. They want one number, updated regularly, accessible instantly.

Teamwork is designed to answer the agency’s operational questions: which clients are over budget, which projects are behind schedule, which team members have capacity, how should we invoice this client this month. These are legitimate and important questions for the agency. They are not the question the client is asking.

HourTab is designed to answer the client’s question: a single page, publicly accessible via a URL, showing the client their current hours used, hours remaining, billing cycle reset date, and a log of what was worked on this cycle. The client doesn’t need an account. They don’t need to understand any project management concepts. They click their bookmark and see their balance.

These are different tools solving different problems for different users. Teamwork solves the agency’s operational and billing problems. HourTab solves the client’s self-serve information problem. The combination of both eliminates the friction that exists when the agency has complete visibility and the client has none.

The Teamwork + HourTab workflow for retainer agencies

For agencies using Teamwork as their primary project management platform, integrating HourTab requires no changes to the existing Teamwork workflow. The steps:

Teamwork manages the project work: task management, team collaboration, project status tracking, milestone management, and all the operational project activity the agency runs for each client. Team members log time in Teamwork against tasks, or use the built-in timer. Teamwork’s internal retainer tracking gives the account manager real-time visibility into budget utilization.

HourTab provides the client-facing layer. Once per week, the account manager exports a time report from Teamwork filtered by client and current billing period. The export is a CSV of time entries — date, team member, task, hours logged. Upload that CSV to HourTab. HourTab parses the entries, calculates hours consumed vs. the retainer cap, and updates the client’s URL with the current balance and work log.

The client has a URL they bookmarked on day one of the retainer. When they click it, they see their current balance, updated as of the most recent CSV upload. For most agencies, once-weekly uploads are sufficient — the client’s information is never more than seven days old, which is current enough for the decision-making the client actually needs. The upload process takes about three to five minutes per client.

Agencies that prefer a single time tracking source of truth outside of Teamwork (Harvest, Toggl, Clockify) can export from those tools instead. The workflow is the same: filter by client and billing period, export CSV, upload to HourTab. The source of the CSV doesn’t matter to HourTab; any properly formatted time-tracker export works.

Teamwork vs. HourTab: feature comparison

When Teamwork’s retainer billing is sufficient (and when it isn’t)

Teamwork’s retainer billing is sufficient if your clients are actively engaged in Teamwork and willing to use the Teamwork interface to check their own utilization. Some agencies — particularly those doing long-term web development or digital marketing for clients who are themselves tech-comfortable and already using Teamwork — have clients who are active Teamwork users and can navigate to their retainer information independently.

Teamwork’s retainer billing is not sufficient if your clients don’t want to learn Teamwork, don’t want another SaaS account, or if the clients’ primary interest is a quick self-serve hours check rather than a full view of project activity. For agencies where a significant portion of clients fall into this category — small businesses, non-technical founders, clients who use the agency precisely so they don’t have to manage technology themselves — Teamwork’s client portal creates friction that doesn’t serve the relationship.

The test: would your retainer clients answer “how many hours do I have left?” correctly without assistance after looking at Teamwork for five minutes? If the answer is uncertain, a HourTab URL answers the question in five seconds with no Teamwork knowledge required.

How Teamwork compares to other agency project management tools on retainer billing

It is worth noting where Teamwork stands relative to other tools commonly used by agencies:

Asana, Monday.com, ClickUp: No native retainer billing concept. These tools manage tasks, projects, and team workflows but have no built-in monthly hours budget, billing cycle, or retainer tracking. Agencies using these tools manage retainer billing entirely in external spreadsheets or accounting tools. Teamwork’s native retainer feature is a genuine advantage over this group.

Jira + Tempo: Jira’s native time tracking is minimal; Tempo Timesheets (the standard Atlassian Marketplace add-on) provides billing-level time tracking and reporting. Tempo handles internal billing reports well but has no client-facing hours URL. Similar to Teamwork in that the billing intelligence is internal.

Basecamp: Deliberately excludes time tracking and billing. Basecamp’s philosophy is that it should not be a billing tool, and it isn’t. Agencies using Basecamp handle all retainer billing in separate time trackers and spreadsheets. Teamwork has substantially more built-in billing support than Basecamp.

Productive, Accelo, Function Point: Agency-specific platforms with more complete billing features than Teamwork, including more sophisticated retainer management and some client portal billing features. These platforms are typically priced higher and require more setup investment. The client-facing retainer visibility is better than Teamwork’s but still generally requires client login to the platform.

Across all of these categories, the common limitation is the same: internal billing intelligence is not the same as no-login client-facing balance information. HourTab fills the same gap regardless of which project management platform the agency uses internally.
