BigTime

enterprise

Professional services automation software with time tracking, billing, invoicing, and project budgeting for mid-market firms.

9.1/10
Overall
Features9.1/10
Ease of Use9.0/10
Value9.2/10
Standout feature

Timesheet lock period enforcement prevents invoicing from drifting after approvals.

BigTime is built for organizations that need controlled timesheet approval and repeatable invoicing from the same source of work. Core capabilities include clock-based and manual time entry, approval workflows with timesheet lock periods, expense logging, and invoice generation tied to approved hours. Reporting spans project profitability roll-up and billing visibility, with utilization-style outputs designed for operational monitoring. Admin controls cover user permissions and auditability for changes across timesheets and billing objects.

A key tradeoff is that billing accuracy depends on enforcing a disciplined entry and approval process, especially when teams use both stopwatch capture and retroactive updates. BigTime fits best when billing rules are consistent per client and project, and when recurring invoice scheduling reduces manual invoice preparation. Teams that need heavy customization of invoice layouts or accounting mappings may find the configuration work non-trivial compared with simpler time trackers.

Pros
  • +Approval workflows tie changes to invoice-ready source data
  • +Recurring invoice scheduling reduces manual invoice preparation
  • +Project profitability roll-up supports billing and delivery visibility
  • +Admin permissions and audit trail support governance over edits
Cons
  • Billing depends on strict timesheet discipline and lock behavior
  • Invoice customization can require configuration work

Value8.6/10
Standout feature

Approval-driven invoice readiness that ties edited and approved timesheets to billing outputs.

Hubstaff’s time capture supports both stopwatch entries and retroactive timesheet editing, then routes approvals based on configured workflows. Invoice generation can pull from project activity and time records, which reduces manual reconciliation when clients expect hourly or retainer-based billing. Reporting groups tracked work by project and user, then highlights utilization and profitability drivers through aggregated roll-ups.

A key tradeoff is that bill rate logic and accounting output depth depend on how projects are structured inside Hubstaff, so teams with complex billing schemes may need extra process discipline. Hubstaff fits best when work can be mapped cleanly to projects and when internal approvals must happen before invoices are issued.

Pros
  • +Timesheet approvals connect directly to invoice-ready time records
  • +Project roll-ups support utilization and profitability reporting by owner
  • +Web and mobile tracking reduce gaps between field and office work
  • +Admin configuration enables consistent worklog governance across teams

How to Choose the Right time tracking and invoicing software

This buyer's guide covers time tracking and invoicing software built to convert recorded work into invoice-ready outputs, with BigTime, Harvest, and Hubstaff leading on controlled approval to billing flows. It also includes Bonsai, QuickBooks Online, Paymo, TimeCamp, Bill4Time, ClickTime, and Xero to cover different approaches to recurring invoice scheduling, billable-hour line creation, and project-level reporting.

The strongest systems connect timesheets to invoice generation with consistent governance, including BigTime timesheet lock period enforcement and Hubstaff approval-driven invoice readiness. The comparison also tracks how each tool handles invoicing workflows and reporting output that support project profitability roll-up and reconciliation accuracy.

Time Tracking and Invoicing Software for approval-controlled invoice generation

Time tracking and invoicing software records work as time entries and then uses those entries to generate invoices through configured billing rules, recurring invoice scheduling, and invoice line item mapping. The workflows often depend on a timesheet approval workflow that can lock the underlying time source to prevent invoice drift after signoff.

BigTime enforces a timesheet lock period so invoice generation stays tied to approved time records. Harvest links time and expense activity to project profitability roll-up so billable utilization and margin views align with the invoice outputs at the project level.

Core evaluation features for time tracking and invoicing workflows

Good time tracking and invoicing software does not just record hours. It turns approved time into invoice-ready line items through a governed workflow that prevents invoice drift after signoff.

The highest-impact differences show up in how approvals, recurring invoice scheduling, and project-level profitability roll-ups connect to invoice generation without forcing manual re-entry or reconciliation work.

  • Timesheet approval control tied to invoice readiness

    BigTime enforces a timesheet lock period so invoices cannot drift after approvals. Hubstaff ties edited and approved timesheets directly to invoice readiness.

  • Recurring invoice scheduling from the same work records

    Harvest and Paymo generate recurring billing outputs without manual invoice preparation by linking project activity, time, and expense to billing. QuickBooks Online also schedules recurring invoices but relies on clean project coding to keep reporting consistent.

  • Project profitability roll-up linked to invoice outputs

    Harvest builds project profitability roll-up views that tie time and expense activity to margin at the project level. Hubstaff also supports project roll-ups for utilization and profitability reporting by owner.

  • Invoice line item creation from time without rebuilding templates

    Bonsai creates invoices from logged billable hours into line items so teams avoid rebuilding invoice line structures. ClickTime uses retainer drawdown style line control inside recurring invoice scheduling to reduce invoice rework.

  • Approval-to-invoice automation that reduces round-trip reconciliation

    TimeCamp routes timesheet approvals into invoice generation from the same work records to reduce reconciliation loops. Bill4Time also ties approval signoff to invoice-ready line items and recurring billing drafts.

  • Accounting-grade traceability for project-linked invoicing

    Xero ties invoicing output to time entries for audit-friendly traceability and connects recurring invoicing to project time. BigTime complements that governance with a lock period that keeps invoice generation aligned to approved time sources.

How to choose based on governance depth, automation flow, and reporting alignment

A time tracking and invoicing tool should be selected by the workflow it can enforce, not by how many time capture methods exist. The decision hinges on whether approvals lock the time source before invoice generation and whether recurring billing uses the same approved records.

Teams should also match reporting output to billing needs. Harvest and Hubstaff emphasize project-level margin and utilization views, while accounting-heavy setups often expect invoice traceability tied to projects inside Xero or invoice generation inside QuickBooks Online.

  • Choose the invoice safety model: lock or draft-only

    If invoices must never drift after approval, BigTime is built around timesheet lock period enforcement that prevents invoice changes after signoff. If invoice creation can be built from approvals into repeatable outputs but requires careful operational discipline, Hubstaff and TimeCamp both focus on approval-driven invoice readiness from the same work records.

  • Decide whether recurring invoices are computed from project activity or assembled from templates

    For recurring billing that is generated from project activity, time, and expense composition, Harvest and Paymo support recurring invoice scheduling tied to those inputs. If recurring invoices must align to customer and project detail inside QuickBooks Online, that path depends on strict project coding and consistent time capture and approvals.

  • Pick the reporting anchor that matches how profitability is managed

    If project profitability roll-ups must reflect both time and expense activity at margin level, Harvest provides project-level profitability roll-up tied to invoice-ready project reporting. If profitability needs are organized around owner-level utilization and profitability roll-ups, Hubstaff supports project roll-ups built from approved work records.

  • Match invoice line creation speed to the billing style complexity

    For faster time-to-invoice with minimal invoice administration, Bonsai creates invoice line items directly from logged billable hours. For retainer-style billing cycles where invoice line control must reduce manual invoice rework, ClickTime adds retainer drawdown style line control within recurring invoice scheduling.

  • Validate how accounting exports and mappings will be handled

    If invoice traceability and project-linked accounting output inside an accounting platform is a priority, Xero provides project-linked invoicing tied to time entries and supports automation via API. If accounting output depends on round-trip reconciliation and export mapping discipline, Bill4Time and TimeCamp both flag mapping work as a key implementation factor.

  • Check fit for complex billing formats and governance complexity

    If complex billing structures require careful project and rate card setup, Hubstaff can require more configuration to match billing formats beyond time-based billing. If recurring billing templates are likely to need careful alignment to billing policies, TimeCamp highlights template setup as a workflow constraint.

Who time tracking and invoicing software fits best

Time tracking and invoicing software is most effective when the workflow converts recorded work into invoice-ready outputs under a defined approval process. The right fit depends on whether invoicing is driven by locked approvals, recurring schedules, or project profitability roll-ups.

Several tools also distinguish themselves by how much billing administration is required, which matters when billing cycles include retainers or when invoice outputs need finance-grade traceability.

  • Services firms with strict approval-to-invoice controls

    BigTime fits firms that need timesheet approval governance because the timesheet lock period prevents invoice drift after approvals. Hubstaff also fits teams that require approval-driven invoice readiness tied to invoice-ready time records.

  • Agencies running repeatable billing from approved time logs

    Hubstaff is a fit for agencies that want approved time logs to convert into repeatable invoices through timesheet approvals. TimeCamp is also aligned when approval routing should feed invoice generation from the same work records to reduce reconciliation work.

  • Professional services teams managing project margin and utilization in invoice planning

    Harvest fits teams that want project profitability roll-up views that tie time and expense activity to margin at the project level. Paymo supports recurring invoice automation tied to project profitability through role-based rate cards based on time and expense composition.

  • Small service teams prioritizing quick time-to-invoice with less invoice administration

    Bonsai fits small teams that want stopwatch capture to flow directly into invoice line items without rebuilding line structures. ClickTime fits teams managing recurring cycles where retainer-style line control reduces manual invoice rework.

  • Accounting-driven teams that need accounting-native traceability inside a ledger workflow

    Xero fits service teams that require project-linked invoicing tied to time entries for audit-friendly traceability. QuickBooks Online fits accounting teams that want recurring invoice scheduling tied to customer accounts with billable time and project detail.

Common implementation mistakes in time tracking and invoicing

Many failures in time tracking and invoicing software come from workflow mismatches rather than missing features. The most frequent problems show up when approvals are not disciplined, when invoice templates do not match billing policies, or when project coding is inconsistent enough to break profitability and reconciliation outputs.

Another common mistake is expecting advanced finance workflows such as trust account escrow to appear as native modules in time tracking systems.

  • Treating approval workflows as optional when the tool depends on lock behavior

    BigTime assumes strict timesheet discipline because invoice generation ties to the enforced timesheet lock period. If that discipline cannot be maintained, billing outputs will not reflect the intended approved sources.

  • Underestimating setup work for project codes and rate cards used by recurring billing

    Harvest and Paymo depend on consistent project tracking discipline because the project profitability roll-up is only reliable when teams track time and expense consistently. Hubstaff also warns that complex billing structures require careful project and rate card setup.

  • Choosing a platform that fits time entry but not invoice template complexity

    TimeCamp can require careful setup of invoicing templates to match billing policies, which can slow adoption when billing formats are varied. Bonsai limits accounting depth for GL mapping and cost-to-bill rollups, which can force extra export work for finance teams.

  • Expecting advanced payment and trust workflows to exist as native modules

    Bill4Time and ClickTime both focus on approval-linked recurring schedules and role-based rate cards, but Bill4Time does not represent advanced payment workflows like trust account escrow as native modules.
