Every engagement at One Guy Consulting is backed by a clear, itemized invoice so you always know exactly what you’re paying for and when payment is due. Invoices are sent electronically to the email address you provide during onboarding. You’ll receive each invoice with enough lead time to review it, ask questions, and pay before the due date — no surprises.

​
Invoice Schedule

The timing of your invoices depends on the type of engagement you’ve selected. Project-Based Work For fixed-scope projects, billing is split into two stages:
  • Deposit invoice — issued before work begins, typically 50% of the total project fee. Work starts once this invoice is paid in full.
  • Final balance invoice — issued upon delivery of the agreed final deliverable. The remaining balance is due within the standard payment terms.
Monthly Retainer Retainer clients are billed one full month in advance. Your invoice is issued on the same date each month (e.g., the 1st), and the retainer period begins once payment clears. Continued access to retainer services is contingent on the invoice being paid before the new period starts. Advisory Sessions Single advisory or consulting sessions are billed per session. You’ll receive an invoice immediately after the session is booked (or after it concludes, depending on what was agreed), with payment due before or shortly after the session takes place.

​
What’s Included in Each Invoice

Every invoice you receive contains the following:
  • Scope summary — a plain-language description of the work covered by this invoice, tied directly to what was agreed in your project brief or contract.
  • Line items — an itemized breakdown of services, hours, or deliverables being billed.
  • Invoice date and due date — clearly labeled so you know exactly when payment must be received.
  • Payment instructions — the accepted payment methods and any relevant account or link details needed to complete your payment.
  • Invoice number — a unique reference number to use in any correspondence about that specific invoice.

​
Payment Terms

Invoices are due within Net 15 — meaning payment must be received within 15 calendar days of the invoice date, unless a different arrangement has been agreed upon in writing. Late Payment Policy Prompt payment keeps the project on track and ensures your work remains a priority. If an invoice is not paid by the due date, the following steps apply:
  1. Day 3 past due — A payment reminder is sent to your email on file. This is a courtesy notice to flag that the invoice has not yet been received.
  2. Day 7 past due — Active work on your project or engagement pauses. No new deliverables will be produced or delivered until the outstanding balance is settled.
  3. Continued non-payment — If an invoice remains unpaid for an extended period, One Guy Consulting reserves the right to end the engagement. Any work completed to date remains the property of One Guy Consulting until payment is received in full.
If you anticipate difficulty paying by the due date, reach out proactively. Arrangements can sometimes be made — but only if you communicate in advance.
If you spot an error on an invoice — such as an incorrect amount, wrong billing period, or missing information — email support@oneguyconsulting.com within 5 business days of receiving the invoice. Include your invoice number and a brief description of what needs to be corrected. A revised invoice will be issued promptly, and the due date will be adjusted accordingly if the error originated on our end.
If an invoice remains unpaid beyond the 7-day grace period, all active work on your engagement will pause until the balance is cleared. This includes scheduled calls, in-progress deliverables, and any ongoing retainer services. Work will resume once payment is confirmed — typically within one business day of receipt.
