Ideas: financing a one-off marketing campaign
Most marketing finance conversations get straight to the cost of borrowing. The conversation worth having first is about whether the campaign is the right campaign at all. This article walks through the question in order: campaign-fit, then funding-fit.
The campaign-fit question
A campaign is finance-worthy when three things are true:
- You have data — even small data — on what comparable campaigns return. “We’ve never tried paid advertising” is not data; “our previous £400 test returned £1,800 of attributable sales” is.
- The campaign window is short and definite. Three weeks around a launch. The fortnight before Black Friday. The month leading up to an industry event. Open-ended “always-on” advertising is a working-capital expense, not a one-off finance.
- The conversion shape repays inside 60-90 days. E-commerce: yes, almost always. B2B with 30-60 day invoice terms: usually. B2B with quarterly procurement cycles: no — the cash returns too slowly for short-term finance to match.
Sizing the loan
The right loan amount is: tested CPA × target conversions × campaign window × 1.2. The 1.2 multiplier covers the inevitable mid-campaign tweaks (audience reweighting, creative refresh). If the answer comes out to more than 30% of your normal monthly trading inflow, your campaign is too ambitious for the cash position — scale down and re-quote.
The repayment shape
Match the loan term to the cash-return window. A 3-week campaign for an e-commerce store: 30-45 day loan. A 4-week campaign for B2B with 30-day invoice terms: 60-90 day loan. Most short-term lenders, including us, can match either.
The honest decision
The deciding question isn’t “can we get this loan?” but “would we run this campaign with our own cash if we had it?”. If yes and the cash isn’t there, finance bridges the gap. If no, the finance doesn’t change the answer. The business loans calculator handles campaign-sized borrowing (£500-£5,000 typically).
