Comparison Table
Harvest
SMBTime tracking and expense management software with invoicing and reporting for professional services teams.
Role-based approval chains for both time entries and expenses keep finance-facing data controlled.
Harvest is built around project-based time tracking and reconciliation between timesheets, expenses, and what accountants receive. Time entries support granular notes and assignment to projects, while expenses support receipt upload and categorization that aligns with project coding. Approval routing applies at the timesheet and expense levels, which helps service teams control billable utilization before finance review.
A key tradeoff is that bill formatting and e-billing submission formats are not its primary core workload, so firm teams with strict LEDES 1998B and court-specific submission requirements may need a separate billing system. Harvest fits firms that want tight project-to-approval control plus accounting posting via integrations, especially when project managers and cost accountants work from the same coded time and expense set.
- +Time and expenses share the same project context end to end
- +Timesheet and expense approval routing covers signoff before finance handoff
- +Receipt capture keeps expense documentation attached to line items
- +Accounting and PSA integrations reduce manual export and re-keying
- –Advanced litigation billing formats and e-billing submissions depend on external billing tools
- –Complex cost-code trees require careful configuration discipline
- –Utilization reporting depends on consistent project coding by staff
- –Split-billing allocation needs structured setup to avoid post-correction work

How to Choose the Right time and expense billing software
Time and expense billing software connects employee time capture and receipt-backed expense entry to project-coded approval routing and accounting-ready billing handoff. This buyer’s guide covers Harvest, BigTime, Clio, Bill4Time, TimeSolv, BQE Core, Kantata, Zoho Invoice, Deltek, and QuickBooks Time.
The biggest differences show up in approval control depth, how tightly expense and time stay linked to the same project execution records, and how much billing output depends on external billing tools or ERP modules. Harvest and BQE Core emphasize approval routing with a clear chain before finance handoff, while Zoho Invoice relies on Zoho Expense inputs to generate invoice-ready expense lines without rebuilding descriptions.
Time and expense billing software that routes project-coded approvals to billing and accounting
Time and expense billing software records billable time and expense lines under project or matter context, then pushes those transactions through an approval workflow that finance can trust for billing. In practice, tools like Harvest route both time entries and expenses through role-based approval chains tied to the project context so signoff happens before finance uses the data.
In legal and professional services workflows, Clio keeps matter-level status aligned by tying the reviewed time and expenses to matter billing workflow stages. In account-integrated workflows, QuickBooks Time reduces friction by feeding QuickBooks billing context after structured employee time approvals, while expense intake still depends on consistent mapping to QuickBooks accounts during accounting setup.
Approval routing depth, project linkage, and accounting handoff mechanics
A time and expense billing workflow succeeds when every time entry and expense line follows the same approval routing chain into billing and accounting. Harvest, BigTime, and BQE Core win attention for routing depth that keeps finance-facing records controlled before handoff.
Role-based approval chains that cover both time and expenses
Harvest routes both timesheet approvals and expense approvals using role-based approval chains tied to project context before finance handoff. Bill4Time also supports time and expense approval paths, but its automation depth can feel limited for complex routing chains.
Project or matter linkage that keeps reviewed work tied to billing status
Clio anchors reviewed time and expenses to matter billing workflow stages using matter-level status. Kantata keeps approval history attached to the same project execution records used for billing.
Receipt capture that attaches images to expense line items
BigTime captures mobile receipts and attaches images to specific expense line items to speed expense report reconciliation. Clio also reduces manual rekeying by using mobile receipt capture for expense reports.
Billing-impact controls such as write-down tracking
TimeSolv includes built-in write-down tracking with billing impact visibility during billing workflows. It pairs this with matter-level time capture to support structured billing export decisions.
Rounding and adjustments that follow the same approval path
Bill4Time configures time rounding and adjustments so they follow the same approval path as billing workflows. Harvest instead focuses on end-to-end sharing of project context across time and expenses before finance uses the data.
Configurable approval routing at the matter level with billable edits
BQE Core supports matter-level approval routing with billable edits before invoice generation. That matters when service firms require multi-step signoff that ties into invoice finalization rather than post-processing.
External system integration for time capture and invoicing readiness
Zoho Invoice relies on Zoho Expense receipt-driven expense lines to create invoice-ready items without rebuilding descriptions. QuickBooks Time fits firms that already use QuickBooks by feeding QuickBooks billing context after structured employee time approvals.
Choose the approval chain and accounting handoff model that matches internal governance
The deciding factor is where approvals happen relative to billing output creation. Harvest and BQE Core keep approval routing ahead of finance handoff, while Clio ties reviewed entries to matter billing workflow stages so billable status stays aligned.
Map the time and expense approval chain to the same ownership boundary
If approval signoff must happen for both time and expenses before accounting handoff, Harvest provides role-based approval chains that cover time entries and expenses. If approvals must align to matter billing workflow stages, Clio keeps the reviewed time and expenses tied to matter-level status for billing.
Pick the project linkage model that matches how billing records are created
If billing depends on project execution records that must retain approval history, Kantata keeps approval history associated with the project workflow records used for billing. If billing output depends on invoice generation with billable edits, BQE Core routes matter-level approvals into invoice finalization with edits before generation.
Decide whether expense reconciliation friction is solved in the expense tool or in invoicing
If expense reconciliation should minimize retyping, Zoho Invoice converts Zoho Expense receipt-driven lines into invoice-ready items without rebuilding descriptions. If expense reconciliation should stay inside a unified billing workflow, BigTime attaches mobile receipts to expense line items and ties the expense entries into report lines via approvals.
Select a billing-impact control level that fits margin governance needs
If write-down visibility must appear during billing workflows, TimeSolv includes built-in write-down tracking that shows billing impact alongside matter-level approvals. If controlled billing outputs must follow time rounding and adjustments inside the approval path, Bill4Time keeps those adjustments aligned with the same approval path.
Choose between controlled configuration and dependency-heavy workflows
If the firm wants to keep approvals and billing inputs within the same configuration system, Bill4Time and Deltek provide project and client billing configuration that controls time rounding, adjustments, and cost code driven inputs. If the firm already uses QuickBooks or needs Zoho invoicing, QuickBooks Time and Zoho Invoice shift some workflow dependency into QuickBooks or Zoho modules.
Plan for governance work where the cost structure and allocations are complex
If complex cost-code trees or multi-step approval chains require careful configuration discipline, Harvest notes that complex cost-code trees need careful setup. If allocation rules are complex across projects, BigTime calls out that complex allocation rules demand careful setup to avoid reconciliation drift.
Which service firms benefit from these time and expense billing workflow models
Time and expense billing software fits service firms that must route billable time and receipt-backed expenses into approval-controlled billing and accounting outputs. The strongest fit depends on whether the firm’s governance center is project approvals, matter billing stages, or invoice readiness from an existing expense intake workflow.
Professional services firms that require role-based approval control across both time and expenses
Harvest keeps time and expense approvals on a shared project context so signoff happens before finance handoff. This reduces the risk of finance receiving expense lines that bypass the same approval controls used for time.
Legal teams that run matter-first billing workflow stages
Clio ties reviewed time and expenses to matter billing workflow stages so billable status stays aligned to the matter. TimeSolv also emphasizes matter-level time capture and write-down tracking during billing workflows.
Firms that need mobile receipt capture with attached images for faster reconciliation
BigTime attaches mobile receipt images to expense line items and links expense entry lines to report lines for faster reconciliation. Clio similarly uses mobile receipt capture to reduce manual rekeying for expense reports.
Operations teams that already operate inside QuickBooks or need QuickBooks billing context
QuickBooks Time fits firms that want controlled employee time approvals feeding QuickBooks billing context without requiring a separate PSA layer. This reduces friction for teams already living in QuickBooks structures.
Service firms standardizing invoicing flows through Zoho Expense to Zoho Invoice
Zoho Invoice fits firms using Zoho Expense because receipt-driven expense lines flow into invoice-ready items without rebuilding descriptions. This keeps the invoicing step closer to expense intake and reduces manual invoice line work.
Common implementation pitfalls in time and expense billing workflows
Most failures come from misaligning approvals with the accounting or billing object that finance expects. Other failures come from assuming mobile receipts automatically translate into invoice-ready or GL-ready lines without disciplined mapping.
Approvals that cover time but allow expense lines to bypass the same routing boundary
Harvest covers both timesheet approvals and expense approvals using project context so finance receives signoff-complete records. Bill4Time also keeps expense capture tied to billing records through its approval path, but teams should validate end-to-end routing for all expense entry types.
Relying on a matter or project workflow without maintaining consistent governance discipline
Clio calls out that governance takes discipline to keep approval routing and billing rules consistent. BQE Core also notes that approval edits and billable edits increase the need for consistent configuration for allocations and billing rules.
Underestimating the setup effort for complex allocation rules and cost structures
BigTime flags that complex allocation rules demand careful setup across projects. Deltek similarly notes that cost structure setup and workflow configuration require disciplined setup to keep billing inputs consistent.
Assuming billing output formats or e-billing submissions are fully handled inside the time and expense tool
Harvest specifically states that advanced litigation billing formats and e-billing submissions depend on external billing tools. TimeSolv also warns that bill formatting and e-billing submission workflows can take setup time.
Mapping accounting details without aligning the accounting system’s chart of accounts and structure
QuickBooks Time calls out that accounting detail mapping depends on QuickBooks account setup discipline. Zoho Invoice notes that ledger-level controls for bill-to-GL mapping require careful configuration.
