Use this page when Basecamp holds the work history and you need an invoice that reflects billable tasks, people, dates, and expenses. Basecamp supplies the project and to-do context, while the invoice record needs commercial fields such as invoice number, client details, payment terms, descriptions, rates, amounts, tax treatment, subtotals, and totals.
Basecamp itself is the source of work context, not the final accounting system. Its project data can include identifiers, names, status, descriptions, and client-company details when present. To-do records can identify the work item through title or content, parent list, project, assignees, dates, and completion status. Those details help you describe billable work clearly instead of sending a vague hourly total.
A clean Basecamp billing workflow starts by deciding which projects, to-dos, and time entries belong on the invoice. Basecamp timesheet-style data is structured around date, hours, description, person, project, and parent recording, such as a to-do, message, card, document, upload, schedule entry, or project timesheet. Those fields become the practical source for invoice breakdowns.
The invoice should group work in the format your client expects. A project-level invoice works for retainers and simple monthly services. A task-level breakdown works better when the client reviews specific deliverables. A person-level breakdown fits staff augmentation or specialist billing. Each line needs a description, quantity of hours, rate, amount, and any billable expense that belongs with the work.
United States private-sector invoices do not follow a single federal invoice form or a national VAT or GST invoice regime. Invoices are supporting documents for business records, and sales and use tax obligations come from state and local rules. Tax treatment depends on nexus, the taxable product or service, the customer location, and the applicable state and local rate.
Avoid treating every Basecamp project as taxable in the same way. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas defines 16 broad categories of taxable services. A seller that makes taxable sales may need a state seller permit or sales-tax account where required, but there is no United States VAT or GST registration number for ordinary invoices.
A one-off invoice tool is enough when you have a short Basecamp project, a single client, and a small set of lines you can review manually. It gives you a finished document without installing another system. This works well for a standalone invoice, a corrected draft, or a project where the time data already sits in a clean export.
A managed workflow matters when Basecamp work repeats every week, several people log time, and invoice accuracy depends on approvals, rates, and reporting. Everhour can connect Basecamp work context to customizable reports with 45+ columns, filters, grouping, exports, scheduled email delivery, and profitability views, then billing can use approved data instead of reconstructed notes.

Basecamp stores project work, tasks, messages, schedules, and time-related context, but it is not the final invoicing or accounting system for most billing workflows. A practical setup uses Basecamp as the source of billable work, then sends approved time, task descriptions, rates, expenses, and totals into an invoice generator or accounting workflow.
Project name, to-do title, assignee, date, hours, description, and completion status matter most because they explain the work behind each invoice line. Client-company data also helps when it is present on the project. These fields let you group charges by project, task, person, or date instead of sending one unexplained amount.
A Basecamp invoice should show every to-do separately only when the client reviews work at that level. Monthly service clients often prefer project or phase summaries with hours and totals. Clients that approve detailed deliverables need task-level descriptions, especially when different rates, expenses, or billable and non-billable decisions apply across the same project.
United States sales tax should not be applied automatically to every Basecamp invoice. The United States has no national VAT or GST invoice regime, and sales and use tax depends on state and local rules, nexus, service or product taxability, and customer location. A service that is taxable in one state can be exempt or treated differently in another.
The most common dispute comes from invoice lines that do not match the client's view of the work. A line that says "project work, 20 hours" gives the client no task, date range, person, or deliverable to verify. Basecamp task titles, descriptions, dates, and assignees should support the billing narrative before the invoice goes out.
Everhour Reporting lets teams turn Basecamp-linked time into reports with 45+ columns, filters, grouping, date ranges, and exports. Admins can review billable time, non-billable time, costs, invoice status, budget metrics, and project details before the invoice is prepared.
Everhour embeds time tracking controls in the Basecamp web interface through its browser extension, then uses synced project names, task titles, and tags in billing workflows. Billable time can be priced with configured rates, selected as uninvoiced time, and turned into invoices with hours, rates, expenses, subtotals, and totals.
Connect Basecamp work to Everhour reports, review approved billable time, and keep invoice inputs tied to projects, tasks, rates, and profitability.
