The verdict in three sentences
For an office supplies company targeting firms in the City and Canary Wharf, Google Ads on next day delivery queries can open business accounts profitably when each account brings recurring monthly orders. In this fictional but representative case, cost per new account falls from about 520 GBP in month one to about 295 GBP in month six, driven by tighter keywords and a B2B account form plus a WhatsApp option answered within 15 minutes. Over time, the biggest lever is organic visibility on Google, which lowers acquisition cost because not every visit has to be paid for.
Starting point and setup
CityDesk Supplies is a fictional company, built for illustration and never presented as a real client. It delivers paper, toner, kitchen and cleaning supplies and light furniture to offices across central and east London. Before the test, 85 % of new accounts came from referrals and outbound calls.
| Setup element | Choice made | 2026 market ballpark |
|---|---|---|
| Google Ads media budget | Search only, EC1 to EC4, E14 and nearby postcodes | 3,000 to 6,000 GBP a month |
| Campaign management | External specialist | 800 to 1,800 GBP a month |
| Cost per click | "office supplies next day delivery London", "toner delivery City of London" | 1.80 to 4.50 GBP |
| Conversion point | B2B account opening form with VAT number, plus WhatsApp button | Reply target under 15 minutes |
| Qualified enquiries | Quote and account requests | 60 to 140 a month |
| New business accounts | First purchase order received | 10 to 22 a month |
| Average monthly order per account | After 3 months | 350 to 1,400 GBP |
Kolonell's prices for this kind of setup are separate: a paid campaign setup costs 100,000 FCFA (about 152 EUR), and monthly SEO ranges from 100,000 to 350,000 FCFA (about 152 to 534 EUR) depending on the plan.
Month by month results
| Month | Media spend | Clicks | Qualified enquiries | Accounts opened | Cost per account (media plus management) |
|---|---|---|---|---|---|
| 1 | 3,500 GBP | 1,150 | 52 | 9 | 522 GBP |
| 2 | 3,500 GBP | 1,260 | 64 | 12 | 392 GBP |
| 3 | 4,000 GBP | 1,450 | 79 | 14 | 371 GBP |
| 4 | 4,500 GBP | 1,640 | 96 | 17 | 335 GBP |
| 5 | 4,500 GBP | 1,700 | 104 | 19 | 300 GBP |
| 6 | 5,000 GBP | 1,880 | 118 | 21 | 295 GBP |
Calculation: cost per account = (media spend + 1,200 GBP management) divided by accounts opened. In month six, (5,000 + 1,200) / 21 = 295 GBP.
What brought the cost down
Generic terms such as "stationery" were excluded in favour of business intent queries. The account form asked only for company name, VAT number, delivery postcode and contact, cutting abandonment. A sales rep called every enquiry within the hour to offer 30 day payment terms and a first order discount.
Email follow ups to new accounts complied with UK GDPR and PECR rules for business contacts, with a clear opt out in every message.
Profitability and the role of organic search
With an average monthly order of 700 GBP and a 25 % gross margin, each account brings about 175 GBP of margin a month. A 295 GBP acquisition cost pays back in under two months if the account stays active. Over 12 months at 70 % retention, each account yields roughly 1,450 GBP of margin.
The limit is that every click is paid for, and London click prices rise as competitors bid on the same queries. Ranking organically and on Google Maps for "office supplies Canary Wharf" reduces that dependency. That is what Kolonell's Traffic Engine is for: being found on Google by the businesses searching for your service, with a weekly report on the enquiries generated.

Mini case study
Illustrative example: Tom, commercial director of CityDesk Supplies, compares two 12 month scenarios. Paid only: 54,000 GBP media and 14,400 GBP management for about 220 accounts, about 310 GBP per account. Mixed: paid search trimmed to 3,500 GBP a month plus a Traffic Engine Momentum plan at 225,000 FCFA (about 343 EUR) a month and a 300,000 FCFA (about 457 EUR) setup. If organic search adds 6 accounts a month from month four, cost per account drops towards 240 GBP, with an asset that keeps producing after ads stop.
FAQ
What Google Ads budget does a London B2B supplier need in 2026?
The 2026 market ballpark is 3,000 to 6,000 GBP a month in media plus 800 to 1,800 GBP in management. Below about 2,000 GBP, click volume is often too low to optimise.
Does WhatsApp work for B2B in London?
As a secondary channel, yes: in this case about 30 % of enquiries came through WhatsApp, mostly office managers on the move. The account form remains the main route because it captures VAT and billing details.
How long before results are reliable?
Allow 2 to 3 months to stabilise cost per account. Here it fell by 43 % between month one and month six.
Can organic search replace Google Ads?
It complements it: organic results take 3 to 6 months but you do not pay per click. Traffic Engine starts with a 100,000 FCFA (about 152 EUR) visibility audit, deducted from setup if you start within 30 days.
How should we track cost per account?
Tag every enquiry by source and link the first purchase order to it. A weekly review is enough to adjust bids.
Get found by the clients looking for you.
