# Set your Finance defaults
> Set the currency, due days, document numbering, tax and shipping defaults DMLY copies onto every invoice you raise.
Finance settings hold the defaults DMLY copies onto your documents as they are created: the
currency you bill in and how long a client has to pay (invoices only), how your documents are
numbered (invoices, orders and expenses), and how tax and shipping are applied (invoices and
orders). Expenses carry their own default currency on the Expenses tab.
Set these before you raise your first invoice. Defaults are **copied at the moment a document
is created**, not linked to it — changing a default later leaves every document you already
issued exactly as it was. Fixing a wrong default on a sent invoice means
[voiding and re-issuing](/finance/invoices) it, not editing the setting.
## Invoice defaults
| Setting | What it does |
| -------------------- | --------------------------------------------------------------------------------------------------------------------- |
| **Default currency** | The currency each new invoice is raised in. |
| **Default due days** | The due date is the issue date plus this many days. An invoice past its due date is marked **Overdue** automatically. |
| **Invoice notes** | Copied onto each new invoice. |
**Default due days** ships as `0`. Left at `0`, invoices are raised with no due date at all and
never go Overdue — set it to 1 or more if you want due dates.
Your default terms are copied onto each new invoice too.
If you leave **Default currency** empty, DMLY works the currency out in order: the currency
on the invoice's own lines, then your workspace's business currency, then US dollars as a
last resort. Setting it explicitly is better than relying on that.
Every line on one invoice must be in the same currency — DMLY does not convert between
currencies, and an invoice whose lines disagree with *each other* is rejected. A default
currency that disagrees with your Offerings' prices is not rejected: it is applied anyway,
the amounts are not converted, and the invoice silently misstates the money. Set your
default currency to match the currency your Offerings are priced in.
## Document numbering
Each document type has its own prefix and its own running counter, per workspace. Out of the
box:
| Document | Prefix | First number |
| -------- | ------ | ------------ |
| Invoice | `INV` | `INV-0001` |
| Order | `ORD` | `ORD-0001` |
| Expense | `E` | `E-0001` |
Numbers are padded to four digits and are unique within your workspace — DMLY will never
issue the same number twice, even if two people create invoices at the same moment.
Only the **Invoice prefix** and the **Expense prefix** are editable — you set them on the
Invoice and Expenses tabs. The order prefix is fixed at `ORD` and cannot be changed. Change a
prefix you can edit and it applies to documents created from then on; numbers already issued
keep the number they were given.
If your accountant needs a particular numbering format, agree it before you start
invoicing. There is no renumbering of documents you have already issued.
## Invoice branding
The invoice PDF and print view are branded from your **workspace's business details**, not
from anything in Finance settings: your workspace name is used as the business name, along
with your logo, address, email, phone and registration number. Update your business details
and every invoice you generate afterwards picks them up.
The PDF downloads as `invoice-.pdf` — for example `invoice-INV-0001.pdf`.
## Tax
Tax is applied exactly as you configure it. DMLY does not work out what you owe, and does
not file or report anything on your behalf. Confirm your rates with your accountant before
you invoice.
Three things about tax are worth knowing before you set a rate:
* **A Service can override the workspace rate.** When an invoice is generated from an
[appointment](/appointments/payments), a tax rate set on that [Service](/appointments/services)
wins over your workspace default. If a booking invoice shows tax you did not expect, check
the Service before the workspace setting.
* **Coupons discount the total including tax.** A percentage coupon takes its percentage off
the subtotal *plus* tax, so it behaves as a percentage off the total the client sees. See
[Coupons](/finance/coupons).
* **Shipping is only taxed if you say so.** See below.
## Shipping
Shipping and other charges on an invoice are **not taxed by default**. Tax applies to them
only when you turn on **Apply tax to shipping**, and then at your workspace's default product
tax rate — falling back to the default service rate — rather than at any line's own rate.
**Apply tax to shipping** has no effect unless a tax on the Taxes tab is marked as applying
to all products or to all services. With the toggle on and neither default set, DMLY charges
no tax on shipping and gives you no warning.
If your shipping charges should carry tax in your country, turn it on before you invoice —
an invoice already sent keeps the tax it was issued with.
## Expense classification
Your vendors, expense categories and expense accounts are also managed under Finance
settings. They are the lists you pick from when recording an expense — see
[Expenses](/finance/expenses).
## What is not here
Connecting Stripe, PayPal, Paystack, Razorpay, MyFatoorah or Mercado Pago, and setting
each one's webhook.
What you charge lives in Offerings. Finance settings only cover the defaults wrapped
around those prices.
Nothing on this page affects what you pay DMLY. That is a separate system.
