Built forConsultants

Invoicing built for independent consultants

Q: How do retainers work?

Log the retainer as a flat-rate line each period, or track hours against it. Either way it lands on a clean monthly invoice you send in one click.

Q: Is this built for a solo consultant?

Yes. There’s no professional-services-automation bloat, just fast time logging and professional invoices sized for an independent advisor.

Whether you bill by the hour, the day, or a monthly retainer, your time is the product. Cake logs it cleanly per client so invoicing never eats into billable hours.

Made for advisory work

Billing that respects your time

Hourly, day-rate, or retainer, logged per engagement and billed clean.

Log advisory time as you go

A two-hour strategy call, a full workshop day: log it against the client and Cake prices it from your rate. Your billable total is always accurate.

Keep engagements separate

Several clients on the go at once, each keeps its own rate and running total, so nothing crosses wires at invoice time.

Invoices that read professionally

A clean, itemized PDF that matches your rate. Your client’s finance team processes it without a second email.

FAQ

Questions, answered

Can I bill by the hour and by the day?
