The verdict in three sentences
For a London beauty brand supplying hair salons, spas and independent pharmacies, a trade portal with customer-specific pricing typically costs £30,000 to £60,000 ex VAT in 2026. The storefront is the cheap part: the budget goes into account-level price lists, ordering rules and a reliable two-way sync with your ERP or accounting system. Brands recover the investment through fewer order-desk hours, fewer pricing errors and stockists who reorder at 11 pm without waiting for a rep.
What a beauty trade portal has to handle
Your stockists do not share one price. A Mayfair salon group has net prices agreed per SKU, a chain of pharmacies negotiated a tiered discount, and a new independent salon sits on the standard trade list. The portal must show each logged-in buyer their own prices, their own assortment (professional back-bar sizes for salons, retail packs and point-of-sale material for pharmacies) and their own terms.
Ordering rules belong in the system rather than in a rep's memory: a minimum order value of £250, free delivery above a threshold, 30-day invoice terms for approved accounts and card payment upfront for new ones. Product compliance matters too, with batch numbers, ingredient lists and safety information downloadable from each product page. Since buyer contact data is personal data, the build also needs UK GDPR basics: a lawful basis, retention rules and access controls per user.
| Feature | What it fixes | 2026 market ballpark (ex VAT) |
|---|---|---|
| Price lists per account and per range | No more manual discount maths | £5,000 to £10,000 |
| Assortment by channel (salon or retail) | The right catalogue for each stockist | £2,500 to £5,000 |
| Minimum order value and carriage rules | Fewer unprofitable small drops | £1,000 to £3,000 |
| 30-day terms with credit limits | Controlled exposure without chasing | £3,000 to £7,000 |
| ERP or accounting sync (items, stock, prices, orders) | No rekeying, trustworthy stock | £10,000 to £22,000 |
| Quick reorder and saved lists | A salon reorders in two minutes | £1,500 to £4,000 |
| Batch data and product safety documents | Faster answers to pharmacists | £1,500 to £4,000 |
The integration line swings the total most. If prices live in your ERP and must flow both ways, expect the upper half of the range; if your team can manage price lists in the portal admin, you can stay close to £30,000.
Comparing your options
London brands usually shortlist one of the provider types below. Rank them on total cost over three years, how many pricing exceptions you have and how easily you could switch provider later.
| Option | Upfront cost | Running cost | Lead time | Best fit |
|---|---|---|---|---|
| B2B features on a SaaS platform (Shopify type) | £8,000 to £20,000 setup | Monthly subscription, public price varies by plan, plus apps | 6 to 10 weeks | Simple price lists, stable catalogue |
| Specialist freelancer | £12,000 to £25,000 | Variable, key person risk | 8 to 16 weeks | Small brand, light integration |
| Specialist B2B ecommerce agency | £30,000 to £60,000 | 10 to 18 % of build per year | 12 to 20 weeks | 300 to 2,000 accounts, ERP link |
| ERP partner or systems integrator | £45,000 to £100,000 | Support retainer | 16 to 28 weeks | Multi-brand group, complex flows |
| Kolonell (nearshore team in Dakar) | Medium to complex custom app: 6,100 to 22,870 EUR and up (4,000,000 to 15,000,000 FCFA and up) | Premium maintenance 183 EUR (120,000 FCFA) per month | Set at scoping | Brands wanting custom build at controlled cost |
Market figures are 2026 ballparks; Kolonell's prices come from its public price list. Whoever you pick, ask for separate lines for the integration, the migration of existing price lists and a pilot with 10 to 20 real stockists.
Mini case study
Illustrative example: Olivia, Head of Sales at a London haircare and skincare brand, serves 450 stockists who order roughly every three weeks, about 7,800 orders a year. Her order desk spends 10 minutes keying each one, and 2.5 % contain a wrong price or SKU, costing around £70 each to fix through credit notes and re-deliveries.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
With a £48,000 portal and 65 % of orders moving online in year one: 5,070 orders × 10 minutes = 845 hours saved, worth £27,900 at £33 per loaded hour. Errors fall from 195 to roughly 95, saving £7,000. Minus £7,000 of annual support, the net gain is about £27,900 a year, so payback lands at around 21 months, and sooner once adoption passes 80 %. The softer win: salon owners place orders after closing time instead of texting their rep.
FAQ
How much does a B2B trade portal cost for a London cosmetics brand?
Plan for £30,000 to £60,000 ex VAT for 300 to 2,000 accounts, as a 2026 market ballpark. The lower end assumes price lists managed in the portal, the upper end a full ERP integration.
Do we need to rebuild our consumer website?
No, the trade portal can sit on a subdomain or behind a login on your existing site. That avoids a £10,000 to £25,000 redesign and lets you pilot with 10 stockists first.
How do we offer 30-day terms safely?
Each account gets a credit limit, and the portal blocks or switches to card payment once it is reached. New accounts pay upfront for their first 3 months; for statutory interest on late payments, check the Late Payment of Commercial Debts legislation on GOV.UK.
How long does a launch take?
Count 12 to 20 weeks with a specialist agency, including 3 to 4 weeks for price list migration and testing. A SaaS-based setup can go live in 6 to 10 weeks if exceptions are rare.
Will our field reps lose their role?
No, they stop keying reorders and spend the time on new accounts and in-salon education. Freeing 800 hours a year of order desk time is roughly half a full-time role redeployed to growth.
