Receipt Caker builds a consultant invoice in your browser: add your day or hourly rate, the engagement details, and the total updates live as you enter each line.
How do consultants usually bill clients?

What you can do

  • Bill advisory days or hours with per-line totals
  • Reference a named engagement or statement of work
  • Optional tax line calculated on your subtotal
  • Live preview that mirrors the exported file
  • Free watermarked PNG, or Pro PDF with your logo

Day rates and session-based work

Consultancy is often priced in day rates rather than a single lump sum. Add a line for each day or block of days, set the rate, and the quantity times rate gives the line total.

If you bill by the hour for shorter sessions, switch the quantity to hours instead. Receipt Caker does not care which unit you use; it just multiplies quantity by rate.

Tie the invoice to an engagement

Advisory clients usually want the invoice matched to a named engagement, project, or statement of work. Put that reference in the invoice so it maps to their internal records.

A clear engagement reference plus a unique invoice number makes your billing easy to approve and easy to find later, which tends to speed up sign-off on the client side.

Expenses and tax

If your engagement covers reimbursable expenses such as travel, add them as their own line items so the client can see exactly what they are paying for beyond your time.

Enable the tax field if you charge VAT or sales tax, and it is calculated on the subtotal and shown separately. Leave it off if tax does not apply to your work.

You keep control of delivery

When the numbers look right in the live preview, export a free watermarked PNG or a Pro watermark-free PDF branded with your own logo.

Receipt Caker generates the document only. It does not process the payment, email the client, or track paid status, so you keep the invoice moving through your own process.

Frequently asked questions

Can I mix day rates and hourly rates on one invoice?
Yes. Add some lines priced per day and others priced per hour, each with its own quantity and rate. The live preview totals them together into one subtotal, so an engagement that includes both full advisory days and short follow-up calls still produces a single clear invoice.
How do I show reimbursable expenses?
Add each expense as a separate line item with its own description and amount, such as travel or accommodation. Keeping them distinct from your advisory fees makes the invoice transparent and easier for the client to approve, since they can see exactly what is fee and what is a pass-through cost.
Does Receipt Caker track whether the consultant invoice was paid?
No. Receipt Caker creates the invoice document and nothing more. It does not track paid or unpaid status, send reminders, or sync with accounting software. You export the file, send it yourself, and monitor payment through your own records or bank.
Can I add my engagement or SOW reference?
Yes. There is room to include a project, engagement, or statement-of-work reference alongside the invoice number and date. This helps the client match your invoice to the agreed scope and their internal approvals, which usually makes sign-off faster and reduces back-and-forth.
Do I need an account to export my invoice?
No account is needed to build the invoice and export a watermarked PNG for free. If you want a clean, watermark-free PDF and your own logo on the document, you can upgrade to Pro, but the builder itself works without signing up.
Can I brand the invoice with my consultancy logo?
Logo upload is a Pro feature. On the free plan you get a professional layout with a watermark on the PNG export. Upgrading to Pro lets you add your consultancy logo and download a watermark-free PDF that looks fully branded for your advisory clients.
