Use Case
Invoice Generator for Agencies
Agency invoices fail for a boring reason: they reach the wrong inbox without a PO number and sit in procurement for a month. The billing part is easy — the part worth getting right is making an invoice that a client finance team can process without asking you a question.

Billing needs for Agencies
- A client purchase order number on the invoice, because agency invoices usually route through procurement
- Retainer and milestone lines that can sit on the same document
- Scope notes attached to the line, so an over-servicing conversation has evidence
- SAC 998365 for advertising services, or 998311 for management consulting
- Separate billing contact from the day-to-day contact, since they are rarely the same person
Recommended workflow
- 1Quote first, and put a valid-until date on it. Agency scope drifts between the quote and the work, and a dated quote is what you point at when it does.
- 2Ask for the PO number before you invoice, not after. An invoice without one is the single most common reason agency payments stall in procurement.
- 3Bill the retainer and any overage as separate lines. A client who sees one lump sum disputes the whole invoice; a client who sees the overage line disputes the overage.
- 4Send to the finance contact and copy the account contact. Chasing the person who briefed you is chasing someone with no authority to pay.
- 5Follow up on day 3 after the due date, not day 30. Agency payment terms are usually 30 days from receipt, and "receipt" is the date finance logged it, not the date you sent it.

Why agency invoices get stuck in procurement
An agency invoice usually has to satisfy two different people. The account contact knows what the work was and has no ability to release money. The finance contact can release money and has no idea what the work was. An invoice that only makes sense to the first person will sit with the second.
What unblocks it is almost always structural rather than persuasive: a PO number in the reference field, line descriptions that match the wording on the PO, the GSTIN of the contracting entity, and a due date that matches the contract rather than your default. None of that is hard, but all of it is invisible until an invoice is 45 days late.
- Put the PO number in the invoice reference field, not in the body text
- Match line wording to the quote or PO wording, even where a better description exists
- Name the contracting entity exactly, including Pvt Ltd or LLP
- State the payment term as a date, not as "Net 30"
Retainers, milestones, and the month they collide
Most agencies run both models at once — a monthly retainer for ongoing work and milestone billing for projects. The friction arrives when a project milestone lands in a retainer month and the client sees two invoices in the same week from the same agency.
Putting both on one invoice with clearly separated sections is usually better than two documents. It gives the client one thing to approve, one payment to make, and one due date to track, and it makes the retainer look like the baseline it is rather than a competing charge.
Frequently Asked Questions
What SAC code applies to agency work?
Advertising services are usually SAC 998365. Management and consulting work is 998311, and design services fall under 998391. If an invoice mixes them, put each on its own line with its own SAC rather than picking one for the whole invoice.
Should a retainer be invoiced in advance or in arrears?
Either works, but the GST liability follows the invoice date or the payment date, whichever comes first. Invoicing a retainer in advance means the tax is due that month even if the work happens the next one — worth knowing before you change billing cycles mid-year.
How do I invoice for work beyond the agreed scope?
As a separate line on the same invoice, with the approval reference in the line description. Raising a second invoice for overage reads as a surprise; a labelled line on the expected invoice reads as a record.
What if the client wants to be billed by a different entity than the one we contracted with?
Invoice the entity named on the contract, and ask for a written instruction before changing it. The GSTIN on the invoice decides who can claim input credit, so billing the wrong group company means the right one cannot.
