Features

Built for the full lifecycle of a consulting business

Sif covers everything from tracking your hours to paying your team — so you're not stitching together five different tools to run a company of ten people.

Time tracking

Know exactly what your time is worth

Every hour worked can be attached to a client, project, and billing rate. Sif keeps a running total so you never have to reconstruct a month of work from memory at invoice time.

  • Log hours manually or use a running timer
  • Attach time entries to clients, projects, or tasks
  • Multiple billing rates per client
  • Edit and correct entries before invoicing

Expenses

Every cost captured, whoever paid it

Whether it's a billable client expense or an employee paying something out of pocket and needing reimbursement, Sif keeps it all in one place. Nothing falls off the invoice, and your team gets paid back without the back-and-forth.

  • Record expenses per client or project
  • Mark as billable or for employee reimbursement
  • Attach receipts and notes
  • Included automatically when invoicing
  • Trip logs and daily allowances for salary input

Invoicing

From logged work to sent invoice in minutes

Sif calculates the invoice from your time and expense records. You review, adjust if needed, and send. The numbers are right because they come from what you logged — not from manual re-entry.

  • Auto-calculated from time and expenses
  • Professional layout, ready to send
  • Track status — draft, sent, paid
  • Credit notes for corrections and disputes
  • Full audit trail per invoice

Tasks

A task system that keeps up with your team

  • Assign tasks to any team member
  • Link tasks to clients and projects
  • Simple, uncluttered interface
  • No limit on the number of tasks

  • Trip log tracking for mileage and travel reimbursement

  • Salary input reports ready for your payroll provider
