Stacks
Stop doing unpaid admin. Start billing for every hour you work.
Could one tool handle all this? Maybe — here's why we recommend a focused stack instead →
How this stack works
Monday morning: check this week's schedule. Every booking already has client name, project, and meeting type auto-populated — nothing to copy.
What your client sees: A professional booking page that respects their timezone.
Verification: Zero calendar conflicts. Booking link live in email signature.
During every work session: start a Toggl timer. Tag the entry with the client name and project. AI-powered suggestions pre-fill entries after the first week.
Verification: Every billable session has a logged entry. No hours reconstructed from memory.
End of week (Friday, 15 minutes): review your Toggl dashboard. Confirm billable hours per client are accurate. Mark anything non-billable.
Verification: Weekly summary shows hours by client with correct billable status.
Generate invoice from Toggl's native QuickBooks integration. Toggl pushes time entries directly into QuickBooks — no CSV export, no copy-paste. Set payment terms, click send.
What your client sees: A professional invoice with itemized time entries and a one-click payment link.
Verification: Invoice sent with payment link. Automatically logged in QuickBooks.
QuickBooks sends automatic payment reminders at 3, 7, and 14 days if unpaid. When payment arrives, it's recorded and categorized automatically.
What your client sees: A polite automatic reminder if they haven't paid. Nothing else from you.
Verification: Payment recorded in QuickBooks. Cash flow dashboard updated.

Why this stack
Three tools connect natively here. Toggl Track has a built-in QuickBooks integration — not a Zapier bridge, not a CSV export. You track time in Toggl, click export, and QuickBooks receives clean line items ready to invoice. That native connection is the reason this stack is lean.
Zapier appears in this stack as an optional convenience layer (Calendly → Toggl auto-sync), not as load-bearing glue. If you skip Zapier, you lose the automatic time-entry creation when a booking is confirmed. You gain $20/month and one less thing that can break.
The stack's strength is reconstruction-proof time records. Toggl captures time as it happens, tagged to the right client. If a client questions your invoice, you can show them a timestamped log — not a memory-based estimate.
The tools
Clients book themselves. You set your availability, share a link, and Calendly handles time zones, sends reminders, and prevents double-booking. The back-and-forth that eats 2 hours per week disappears.

Could you just use Bonsai?
If you send 2–5 invoices per month and don't need detailed per-client time analytics, Bonsai alone is simpler and cheaper. Bonsai's integrated time tracking, invoicing, and contracts in one tool covers most solo consultant needs cleanly. This stack is purpose-built for consultants who bill hourly across multiple clients and need reconstruction-proof time records that can withstand client scrutiny.
