# Billing and invoicing
## What's the difference between "On Acceptance", "On Completion" and "Recurring"?
Each service has fees in up to three buckets. The totals for each sit at the top of the **Services** tab.
* **On Acceptance**: the invoice is created when the client accepts, and is dated on the day they accept.
* **On Completion**: the invoice is dated on the proposal's **Service End Date** by default. You can bring that date forward, or split the work into several invoices, milestone-style.
* **Recurring**: billed every month or week (see the next question) across the service period.
## What does Recurring Services on the Details tab do?
It only applies to **recurring** fees. It sets how often recurring services bill: **Monthly** (the default) or **Weekly**, plus **Quarterly** where your site offers it. **Invoice day** sets which day they're issued, and **Due** sets the payment terms. The line underneath reads it back, for example *12 monthly invoices on the 28th, each due 14 days later*.
It does **not** control On Acceptance or On Completion invoices.
## Can one service bill on a different frequency from the rest?
Yes. Open the service's **Edit** window and, under **Recurring**, set **How often**: like the proposal, **Monthly**, **Quarterly** or **Half-yearly**. **Annual** is offered when the service period is longer than a year. On a one-year proposal, put a once-a-year fee in **On Acceptance** or **On Completion** instead.
## If a client accepts some time after the proposal is sent, which date goes on the invoice?
The **date they accept**. On Acceptance invoices are dated on acceptance, not on the day the proposal was sent.
## Why does a recurring fee say "8 of 12 periods" or "4 on acceptance"?
The service period has already started. If the **Service Start Date** is in the past when the client accepts, the periods that have already gone by are billed together on acceptance, and the rest are scheduled as normal. In the example below, 4 monthly periods have passed, so they are added to the On Acceptance invoice and the remaining 8 are scheduled.
## Where can I see every invoice a proposal will raise?
On the **Billing** tab. It shows the full schedule: what is invoiced on acceptance, each recurring run (click **Show the invoices** to list them) and what is held until completion.
## Can I invoice an On Completion fee before the Service End Date?
Yes. On Completion invoices default to the **Service End Date** (often the end of the financial year), but you don't have to wait. Change the **Invoice date** on the **Billing** tab. You can do this from the proposal, the Opportunity or the job.
To bill one service on its own, for example when it finishes before the rest, click **Invoice separately**.
## Where do I see the invoices once they're in Xero?
On the **Xero** tab. It shows the Xero site and tracking category the proposal bills to, and every invoice raised from it, with what is outstanding, overdue and paid. Click **Sync from Xero** to pull in the latest.
## What is the WIP tab for?
It tracks time and costs recorded against the proposal's work, and what has been invoiced from WIP or written off. **To bill** shows anything recorded that the proposal doesn't already cover.
