Best Project Software With Invoicing for Agencies

Harvest keeps the path from hours to invoice short. A team tracks time against projects and tasks, then turns the logged hours into an invoice in a few clicks, with expenses and payments in the same flow. Teams at $9 per seat each month on annual billing adds unlimited projects and clients, while Enterprise at $14 adds approvals and more controls. The free plan covers 1 seat and 2 projects, which suits a solo operator testing the flow.

The trade-off is project depth. Harvest is a time and invoicing tool first, so its task boards and project views are lighter than ClickUp or Asana. Flex usage fees also apply for active projects, clients, tasks, and invoicing on top of the seat price, so an agency should read the pricing page before budgeting. For an agency that wants clean time tracking and fast invoicing without a heavy project system, Harvest is the simplest choice here.

Paymo combines project management, time tracking, and invoicing in one account, which suits an agency that wants a single system for client work. Plus at $10.9 per user each month on annual billing adds unlimited users, clients, and projects, plus timesheet reports and integrations, while Solo at $5.9 a month covers one user. The free plan covers 1 user, 1 client, and 2 projects, with time tracking and invoices included.

The limits are the single-user free and Solo plans, so a team starts paying on Plus, and Gantt charts and dependencies only arrive on Pro at $16.9 per user each month. Paymo also has a smaller integration list than Asana or Monday, so a team that relies on many outside apps should check the list first. For an agency of five or more that wants projects, time, and invoices together, Paymo Plus is a strong value at $10.9.

Avaza prices by account, not by seat, which changes the maths for a growing agency. Startup at $11.95 per month covers the core quote-to-invoice flow, while Basic at $23.95 and Business at $47.95 add more timesheet and admin users. The free plan covers 1 timesheet user, 5 active projects, and 5 invoices a month, with unlimited project collaborators on every plan. An agency can invite clients and collaborators without paying for each head.

The limit is the role pricing. Extra timesheet or admin users cost $7 each per month, so a team of 10 timesheet users pays more than the base plan price, and the interface is less visual than Monday or ClickUp. Avaza also has fewer templates than larger rivals. For an agency with many collaborators and a small core team, the flat account price keeps costs low, and the quote-to-invoice flow covers the billing work end to end.

ClickUp packs tasks, docs, whiteboards, goals, and time tracking into one account, which suits an agency that wants one system for all client work. The free plan covers unlimited tasks and members, plus docs and whiteboards, so a team can run real work on it before spending anything. Core at $9 per user each month on annual billing adds native time tracking, more storage, and guest permissions, which covers the next step for most agencies.

The limit for billing is that native invoicing needs Business at $17 per user each month, so an agency that wants invoices inside ClickUp pays more than the $9 starting price. ClickUp also has so many views and settings that a new team can spend its first week configuring instead of working. An agency that mainly needs tasks and time, and bills from another app, will find Core a strong value, while a team that wants invoicing built in should look at Teamwork or Harvest.

Monday turns client work into colour-coded boards that a whole team can read at a glance, which helps an agency where everyone follows several clients at once. Basic at $9 per seat each month on annual billing adds unlimited boards, docs, and guests, while Standard at $12 adds automations, timelines, and Gantt views. The free plan covers up to 2 seats, so it works for two founders, but a team of five will need a Basic plan from the start.

The limit for billing is that Monday has no native invoicing, so an agency must connect an accounting app or add an invoicing app from the marketplace. Automations also sit on Standard, not Basic, so the real cost for a team that wants those features is $12 per seat each month. An agency that values a clear visual board and already bills from QuickBooks or Xero will get a lot from Monday, while a team that wants invoicing built in should pick Teamwork or Paymo.

Asana gives an agency a clear structure for client work, with projects, sections, tasks, and subtasks that stay tidy as the team grows. Starter at $10.99 per user each month on annual billing adds timeline views, dashboards, and more guests, while the free plan covers up to 10 collaborators with unlimited tasks and projects. That free tier is generous for an agency that mainly needs shared task lists and deadlines.

The limits for billing are clear. Asana has no native invoicing, so an agency must bill from another app, and time tracking needs Advanced at $24.99 per user each month. Reporting is also thin on Starter, with only basic project dashboards. An agency that runs client projects in Asana and bills from FreshBooks or Harvest will find the combination works well, while a team that wants one account for tasks, time, and invoices should look at Teamwork instead.

FreshBooks is an invoicing and accounting tool first, with projects and time tracking added so an agency can bill from the same account it tracks work in. Lite at $23 a month covers 5 billable clients with invoicing, payments, estimates, expenses, and time tracking, while Plus at $43 covers 50 clients and adds proposals and retainers. Premium at $70 removes the client cap and adds project profitability reports. There is no free plan, only a 30-day trial.

The trade-off is project depth. FreshBooks covers tasks, time, and project profitability, but its project views are lighter than ClickUp or Teamwork, so an agency with complex project plans may find it thin. Lite also caps at 5 billable clients, and extra team members cost $11 each per month, so a growing agency should budget for Plus. For an agency that wants billing done right and project tracking as a bonus, FreshBooks is the most finance-first option here.
