Overview

One-off invoices let you bill customers for charges that aren’t part of a recurring subscription. Use them for consulting fees, implementation work, setup costs, or any other ad-hoc charge. Unlike subscription invoices, which are generated automatically from a billing cycle, one-off invoices are created manually and do not recur. They appear alongside subscription invoices in the Billing & Payments tab, but display a billing frequency of Non-recurring and a type of One-time so your customers know it’s a one-time charge.
One-off invoices requires the feature to be enabled for your account. If you don’t see the option to create an invoice on your Billing page, please reach out to Salesbricks Support.

Creating a one-off invoice

You can create a one-off invoice from two places: the Billing page or the Customer page. Either entry point opens the same invoice creation form.

Option 1 — Create an invoice from the Billing page

Go to Billing from the main navigation, then click the New invoice + button in the top-right corner. Select the customer you want to invoice (or create a new one).

Option 2 — Create an invoice from the Customer tab

Go to Customers, select the customer you want to invoice, and click the Billing & Payments tab. Click the New invoice + button in the top-right corner to open the invoice creation form.

Complete the invoice form

As you fill in the form on the left, a live PDF preview on the right updates in real time so you can see exactly what the customer will receive. 1. Fill in the invoice details
  • Accounts payable email — The email address where the invoice will be sent.
  • Purchase order number (optional) — A PO number for the customer’s records.
  • Due date — When payment is expected.
  • Start date / End date (optional) — Define a service period for the charge.
  • Invoice memo (optional) — A short note that appears on the invoice (e.g., “One-time invoice for implementation fees”).

Custom service period: The start and end dates let you define exactly when the service was (or will be) delivered, independent of the invoice or due dates. This is useful for charges like consulting retainers (“Apr 1 – Apr 30”) or phased implementation work that spans multiple months.
2. Add one or more charges Under Invoice details, add each line item you want to bill for:
  • Charge name — The name of the product or service (e.g., “Implementation”).
  • Amount — The dollar amount for the charge.
  • Description — A description that appears on the invoice (e.g., “Implementation of premium plan”).

Multiple charges on a single invoice: Click Add charge + to bundle several line items into one invoice. For example, you could bill “Implementation” at $1,000 and “User Training” at $500 together on the same one-off invoice — the customer receives a single document with both charges itemized.
Use descriptive line items like “January consulting, 10 hours” rather than just “Consulting” so customers clearly understand what they’re being charged for.
3. Apply adjustments (optional) If you need to apply a credit or one-time discount, click Add adjustment + under the Adjustments section. Enter the amount and a memo describing the reason.
Adjustments are a flexible way to apply credits, promotional discounts, or goodwill gestures without changing your line item pricing. The adjustment appears as a separate line on the final invoice (e.g., “Credit for one-time discount: –$100.00”), giving customers a clear record of the reduction.
4. Configure payment options Under Invoice payment, you can optionally check Process the amount due in the invoice using a saved payment method to enable auto-pay. If enabled, choose when the charge should run:
OptionBehavior
Charge on invoice issue dateAuto-pay runs immediately when the invoice is issued. Outstanding invoices will be charged immediately upon switching to this setting.
Charge on invoice due dateAuto-pay runs on the due date based on the set payment terms (e.g., Net 30).
Charge on invoice due date (order form only)Auto-pay runs on the due date for order form orders only. Electronic payment orders are charged immediately.
5. Attach documents (optional) Under Attachments, click Add document + to upload supporting files like a statement of work or signed agreement. You can provide an optional document name and drag and drop a PDF, or click to select a file.
Attachments on one-off invoices are stored at the invoice level only — they are not inherited by subscriptions or other invoices.
6. Choose how to deliver the invoice Under Invoice delivery, pick one of:
  • Create and send invoice now — The invoice is created and the customer is notified via email.
  • Create only — The invoice is created but not sent. You can send it later from the bill statement page.

After the invoice is created

Once created, the one-off invoice appears in the customer’s Billing & Payments tab labeled as One-time to distinguish it from subscription invoices. You can click into it at any time to open the Bill statement page, where you can:
  • View the summary — See invoice totals, line items, service period, billing frequency, and payment terms in one place.
  • Record a payment — Manually mark the invoice as paid if payment was collected outside of Salesbricks.
  • Share the invoice — Send or resend the invoice to the customer.
  • Adjust the invoice amount — Modify the total if needed.
  • Edit details — Update fields like the memo, PO number, or attachments.
  • Regenerate or download the PDF — Get a fresh copy of the invoice document.
The Invoice log on the right side of the page provides a full audit trail of all activity on the invoice.
