In most cases, the obligation of dispatching an invoice falls to the seller or service provider, which is the business or individual that furnishes goods or services. This practice is standard as it ensures proper financial documentation. However, exceptions exist due to specific agreements or unusual transaction circumstances. Ultimately, the onus typically remains with the provider.
Core Duties of the Invoice Issuer
The individual or entity responsible for issuing the invoice plays a crucial role in ensuring the payment process runs smoothly and adheres to compliance guidelines. Here's what they should do:
Delivery of comprehensive details: Essential data such as invoice number, date, the identities of buyer and seller, a detailed description of the supplied services or goods, quantity, total amount, payment terms, and applicable taxes should be clearly stated.
Adherence to compliance: The invoice must comply with local taxation regulations and industry standards, including VAT where applicable.
Prompt invoice dispatch: Postponing the sending of invoices might result in delayed payments, impacting cash flow negatively.
Efficient record-keeping: Properly maintained records aid accounting and payment reconciliation.
Managing overdue payments: Sending professional reminders and making necessary adjustments like issuing credit notes form part of the sender's duties.

Tip
Double-check your invoices for legal compliance, particularly in cross-border transactions, to ward off financial or legal troubles.
When Might a Recipient Send an Invoice?
Barring typical arrangements, there are occasions when the recipient might take on invoicing duties:
A self-billing setup, where the buyer drafts the invoice on behalf of the seller, is often used in sectors with automated procurement methods.
Reverse invoicing might arise, for instance, when goods are returned or within certain supply chain logistics.
Some parties might issue a debit note to amend invoices due to mismatches or partial deliveries.
Such arrangements are precise and typically dictated by pre-existing agreements or industry practices.
Are There Any Set Rules for Invoicing?
Deciding who should send an invoice often depends on legal mandates, contract stipulations, and industry norms.
For example, countries operating under VAT or GST, like those in the EU, mandate VAT-compliant invoices for B2B dealings. Contractual agreements may outline specific invoicing roles, and certain industries, such as construction, often have particular billing protocols dictated by project stages.

Mishandling invoice issuance can breed legal or financial repercussions, including tax compliance issues, disputes, or penalties. Always verify local requirements and contractual duties regarding invoicing positions.
How to Identify the Responsible Invoicing Party
Use these guidelines to clarify invoicing duties confidently:
Examine the agreement: Scrutinise the contract or transaction terms to discern invoicing duties.
Grasp industry norms: Typically, the seller or provider is expected to issue the invoice.
Evaluate financial documentation: Ascertain who logs the transaction as income or a pending receivable.
Communicate pre-emptively: Make roles clear before proceeding with transactions to sidestep potential confusion.
Preserve invoice copies: Keep all invoices for future accountability and reference.
This pragmatic approach ensures all parties involved experience clarity and mitigates potential misunderstandings.
