Quoting a commission is a negotiation. Invoicing is an operations problem, and most independent creative technologists treat it as an afterthought — a PDF thrown together after the work is done, with no deposit, no due date pressure, and no plan for what happens if it’s ignored. That gap is where a surprising amount of unpaid work disappears.
What a real invoice needs
At minimum, every invoice should include: your legal or business name and contact details, the client’s name and billing contact, an invoice number (sequential — clients and your own bookkeeping both benefit), the date issued and the due date, a clear description of the work covered (tied to the quote or contract, not a vague one-liner), the amount due, accepted payment methods, and late-payment terms stated explicitly rather than implied. “Payment due on receipt” is not a due date — “Payment due within 15 days of invoice date” is.
Number every invoice, even your first one. INV-2026-001 looks like a functioning business; “invoice” with no number looks like it was created five minutes ago for this one client, because it probably was.
Deposits aren’t optional for project work
A deposit isn’t about distrust — it’s about aligning incentives before any work starts. Standard practice for commissioned creative-technology work is 30–50% up front, due before work begins, with the balance due on delivery or across milestones for longer projects. A deposit does two things simultaneously: it filters out clients who were never going to pay (nonpayment risk shows up immediately, before you’ve invested time), and it covers your costs if a client cancels mid-project.
If a client pushes back hard on a deposit for project-based work, that pushback is information. Established clients with existing vendor relationships sometimes have legitimate net-30 internal processes that make an upfront deposit awkward — that’s a reasonable thing to accommodate with a documented payment schedule instead. A new client who simply doesn’t want to commit money before seeing more work is a different signal entirely.
Structuring milestones on longer projects
For anything running more than a few weeks, break payment into milestones rather than one deposit and one final payment:
- Deposit (30–50%) — due before work starts
- Mid-project milestone(s) — tied to a concrete deliverable (a working prototype, an approved design, a completed draft), not a calendar date
- Final payment — due on delivery, before final files or source handoff where that’s contractually appropriate
Tying milestones to deliverables rather than dates protects both sides: the client isn’t paying for time that didn’t produce anything, and you’re not stuck waiting past a deadline you hit while payment stalls on something outside your control.
What to actually do when payment is late
Don’t skip straight to anger or silence — escalate in stages, in writing, with a paper trail.
- A few days after the due date: a short, friendly reminder. Assume an oversight, not bad faith.
- 1–2 weeks late: a firmer follow-up referencing the specific invoice number and due date, restating your payment terms (including any late fee specified in your contract — this is why stating one upfront matters).
- 2–4 weeks late: a direct message naming the consequence — work pauses on future deliverables, a formal notice period starts, whatever your contract specifies — not as a threat, but as the thing you said you’d do.
- Beyond that: for larger amounts, a collections service or small-claims filing becomes a real option. For most creative-tech invoice amounts, the credible threat of escalation resolves most situations before you actually need to use it.
The single best protection against all of this is upstream, not downstream: a signed agreement with payment terms spelled out before work starts, and a deposit collected before you begin. Chasing an invoice after the fact is always harder than enforcing terms everyone already agreed to.
