An invoice requests a payment from another entity on Lemma, without giving them access to your accounts and without you needing access to theirs. You can bill any entity in your organization, once your entities are grouped into one, or any entity you already have access to — read-only access counts. See Invoice contacts for the full rules on who you can bill from and bill to. Go to Invoicing to send one.

When to use an invoice instead of team access

If two entities transact often and it’s fine for both sides to see the shared history, add each other as team members so someone can move money directly. Use an invoice for the opposite case: two entities do business but neither should see the other’s balances or transaction history. For example, two independently owned practices refer patients to each other and periodically settle a referral fee. Neither wants the other to see their bank balance, so instead of sharing account access, one sends the other an invoice for the agreed amount. Invoices are also useful when someone can propose a payment but shouldn’t be able to move money themselves. A read-only member of one entity who is also an owner of another can send an invoice from the entity they own to the entity where they only have read access — the recipient’s own owner still decides whether to pay it.

Line items

Every invoice has one or more line items — a description and amount for each service or product being billed. Line items must sum to the invoice total, and they’re locked once the invoice is sent so the record can’t be altered afterward. Use them to give the recipient an auditable breakdown of exactly what a payment covers, instead of a single lump sum.

Another way to keep control: approval rules

Invoicing lets a read-only member propose a payment without ever touching the recipient’s money — the owner on the other side decides whether it goes through. If you want that same kind of oversight on transfers your own team initiates, approval rules are the tool for the job: set a threshold, and any transfer above it waits for an owner’s sign-off before a dollar leaves the account. Pair the two and every dollar moving in or out of your entity has a second set of eyes on it.
