Where a billing currency belongs
An international project needs more than the correct currency symbol on its invoice. The agreed rate, budget, and report must refer to the same currency, or a plausible-looking total can describe the wrong amount. The first question is where the tracker stores that agreement: on the client or on the individual project.
Harvest uses a client currency for its projects, Clockify assigns client currencies on Pro or higher, and Teetrack stores a currency per project. These models support different contract structures. They also need to be distinguished from exchange-rate conversion, which is a separate step when accounts require a total in one reporting currency.
This guide is published by Teetrack, which is included in the comparison. We checked the linked vendor documentation on September 18, 2026. The recommendations are based on that research; we have not tested these products side by side.
| Tool | Best fit | Plan / starting point | Main limitation |
|---|---|---|---|
| Harvest | Currency per client with invoices | Client currency setting; check plan capacity | No automatic currency conversion |
| Clockify | Client currencies in a team workspace | Pro or higher for client-specific currency | Feature is not included in Free |
| Teetrack | Project currencies for individual work | Paid billing and budget features | Single-user plans; separate accounting handoff |
1. Harvest: Currency per client with invoices
Harvest lets an account have a default currency and each client have a preferred one. The client’s currency applies to its projects, which works when all work for that client is billed consistently in EUR, USD, or another agreed currency. Reports separate amounts by currency; including the currency code also distinguishes USD from CAD when both use a dollar symbol.
The client-level model is restrictive if one customer signs contracts in different currencies. Harvest also performs no automatic conversion. Changing an invoice’s currency changes its designation without recalculating the amount, so changing EUR 100 to USD 100 does not apply an exchange rate. Any required conversion must be calculated separately.
2. Clockify: Client currencies in a team workspace
Clockify allows an administrator to define available currencies and assign one to each client on Pro or higher. For a team already using Clockify, that keeps the client’s rates and reported amounts in the agreed currency without introducing another time-recording system. The client remains the point where the currency agreement is stored.
Adding currencies to the workspace and assigning one to a client have different plan requirements. A list containing EUR and USD does not establish that each client can use its own currency on Free. The client assignment requires Pro, and any need to convert those amounts into a common reporting currency should be assessed separately.
3. Teetrack: Project currencies for individual work
Teetrack stores the billing currency with each project’s rate and budget settings. That allows an individual to keep different agreements at the project level, including separate projects for the same client. For example, two hours on a EUR project at 80 per hour produce EUR 160; two hours on a USD project at 100 per hour produce USD 200. The two amounts retain their own meaning in the billing record.
Adding them as an unqualified total of 360 would discard that meaning. Teetrack’s paid billing reports supply project amounts for the invoicing process; exchange-rate accounting still needs its own treatment. The standard plans cover one person, so shared team access is a separate requirement.
Match the currency model to the contract
If a client always pays in one currency, Harvest’s client setting fits that arrangement and carries it through invoicing. Clockify Pro serves client currencies within its existing team workspace. When agreements vary by project, Teetrack’s project setting provides that distinction for individual work.
Keep currency conversion separate in the decision. Recording the correct client amount and calculating its value in your accounting currency are two successive tasks, and the second requires an explicit exchange rate and conversion process.
