Harvest vs toggl for an agency that needs to bill clients accurately

Question

Accepted Answer

Time tracking tools for agencies are not all solving the same problem, and the Harvest versus Toggl comparison is a good illustration of how two tools that both track time can differ enough in practice that the right choice depends almost entirely on what your agency actually needs to do with the data.

Toggl Track is designed around simplicity and adoption. Its primary strength is making it as frictionless as possible for people to start and stop timers, categorize work, and see reports on where their time went. The interface is clean, the mobile and browser extension experiences are polished, and the barrier to getting a team to actually use it consistently is relatively low. Toggl Track's reporting shows time by project, client, and team member with good flexibility. For agencies that want high adoption rates across a team and primarily need time data for internal capacity planning or rough project estimates, Toggl Track tends to win on simplicity.

Harvest is built with billing more explicitly at the center. It has native invoicing capabilities that allow you to turn tracked time directly into client invoices without exporting to another tool. Time entries in Harvest are tied to billable and non-billable categories, and the tool tracks both at once so you always have a clear picture of your utilization rate — what percentage of time your team spent on work you can charge for versus overhead, internal projects, or admin. The invoicing that comes out of Harvest carries the tracked time details, which creates a transparent paper trail for clients who want to see exactly what they're being billed for and at what rate.

For an agency that is billing clients by the hour or on a time-and-materials basis, the Harvest invoicing workflow eliminates a significant manual step. Instead of exporting time data, reformatting it, and importing it into an accounting tool or a separate invoice template, you approve tracked time and generate an invoice in one flow. Harvest integrates with QuickBooks and Xero for accounting, so the invoice that goes to a client also hits your books without re-entry.

Where Toggl has an edge is in its reporting flexibility, particularly for agencies running a lot of internal projects or wanting nuanced views of how time is distributed across work types without necessarily needing to generate client invoices. Toggl's project dashboard views and team reporting can be more visually clear for capacity management discussions. Toggl also typically comes in at a lower price per seat, which matters when you're paying for an entire agency team.

The practical question for a billing-focused agency is how much of your revenue comes from time-tracked billable work that goes directly on client invoices. If the answer is most of it, Harvest's integrated invoicing eliminates enough manual work and potential for billing errors that the product earns its cost difference. If the agency bills on retainer or fixed-fee arrangements where client invoices aren't tied directly to tracked hours, the invoicing integration matters less and Toggl's simplicity and lower cost become more attractive. Many agencies in fixed-fee models use time tracking primarily to understand if projects are profitable, and for that use case either tool works reasonably well.
