The verdict in three sentences
A PrestaShop B2B store converting at 0.8 %, while distributors in its sector run at 2 to 4 %, almost always suffers from three flaws: weak product search, no quick order by SKU and poorly displayed customer prices. A targeted PrestaShop redesign costs 15,000 to 35,000 EUR (about 16,000 to 38,000 USD) and ships in 3 to 5 months, versus 30,000 to 80,000 EUR to migrate to another platform. Unless there is a proven technical limit, the redesign offers the best gain-to-risk ratio.
Why your B2B store converts poorly
A professional buyer does not browse. They arrive with a list of part numbers, often copied from their ERP or an old purchase order, and want to order in 3 minutes. On a store designed like a consumer site, they must search for each product, see a list price instead of their negotiated price and cannot find the pack size. They give up and call the sales rep, or order from a better-equipped competitor.
Audits of PrestaShop B2B stores show recurring causes: 25 to 40 % of searches returning nothing relevant, 4 to 6 second mobile load times on a 15,000-SKU catalog, a 5-step checkout with no net-30 option, and modules piled up over the years that conflict with each other.
Redesign, migration or status quo
| Criterion | Status quo | PrestaShop redesign | Migration to another platform |
|---|---|---|---|
| Cost (2026 ballpark) | 0 EUR | 15,000 to 35,000 EUR | 30,000 to 80,000 EUR |
| Timeline | None | 3 to 5 months | 5 to 9 months |
| SEO risk (traffic loss) | None | Low if URLs are kept | Medium, redirects required |
| Target conversion rate | 0.8 % | 1.8 to 2.5 % | 2 to 3 % |
| Annual maintenance | 3,000 to 8,000 EUR | 4,000 to 9,000 EUR | 6,000 to 20,000 EUR depending on licence |
| Team training | None | Light | Significant |
| When it is the right call | Never beyond a year | Up to 50,000 SKUs, PrestaShop 8 or 9 | Multi-warehouse, very complex B2B, heavy API needs |
Migration makes sense when PrestaShop is genuinely the bottleneck: several companies and warehouses in one catalog, multi-level pricing rules per group and customer, or order volumes that overload the database. In most cases the problem is design, not platform.
Conversion levers and their cost
| Lever | Cost within a redesign (2026 ballpark) | Observed effect on conversion |
|---|---|---|
| Advanced search (typo tolerance, part numbers, synonyms) | 3,000 to 8,000 EUR | +20 to +40 % successful searches |
| Quick order by SKU and list import (CSV, paste) | 2,500 to 6,000 EUR | Order in 2 to 3 minutes instead of 10 |
| Customer prices, discounts and pack sizes shown at login | 2,000 to 5,000 EUR | Fewer drop-offs caused by list prices |
| 2-step checkout with net-30 and PO number | 2,500 to 6,000 EUR | Up to +30 % completed orders |
| Mobile performance (under 2.5 s first render) | 2,000 to 5,000 EUR | Bounce rate down 15 to 25 % |
| Reorder from order history | 1,500 to 4,000 EUR | Higher purchase frequency |
| Module clean-up and upgrade to PrestaShop 9 | 1,500 to 5,000 EUR | Stability, security, speed |
Method matters as much as features: 2 to 3 weeks of audit (search log analysis, session recordings, interviews with 5 to 10 customers), then releases in batches, each measured. For search rankings, keeping URLs and a redirect map prevents traffic loss, which we handle through our SEO offer. The store side is covered on our e-commerce page.
Mini case study
Emma, e-commerce manager at an electrical supplies distributor in Manchester, runs an 18,000-SKU PrestaShop store with 25,000 monthly visits from trade customers, a 0.8 % conversion rate and an average order of 650 EUR (about 560 GBP).
- Current online revenue: 25,000 × 0.8 % × 650 = 130,000 EUR a month, or 1,560,000 EUR a year.
- Cautious post-redesign target: 1.8 %, so 25,000 × 1.8 % × 650 = 292,500 EUR a month.
- Some of those orders already came by phone: counting only 40 % of the gain as new revenue gives 0.4 × 162,500 × 12 = 780,000 EUR a year.
- Gross margin at 22 %: 171,600 EUR a year.
- Redesign cost: 30,000 EUR, plus 7,000 EUR annual maintenance.

FAQ
What conversion rate should a B2B store target?
Well-equipped B2B distributors usually convert 2 to 4 % of logged-in customer visits. Moving from 0.8 % to 1.8 % in the first year is a realistic goal.
Should we leave PrestaShop?
Rarely. Up to 50,000 SKUs and on PrestaShop 8 or 9, a redesign is enough. Migration, at 30,000 to 80,000 EUR, is justified for complex multi-warehouse setups or pricing rules the platform cannot handle.
How long does a redesign take?
Allow 3 to 5 months: 2 to 3 weeks of audit, 8 to 14 weeks of design and development, then 2 to 4 weeks of acceptance testing and phased launch.
Will we lose search rankings?
No, if product and category URLs are kept or redirected one by one. A redesign without a redirect map can cost 20 to 50 % of organic traffic for several months.
Which lever delivers the most?
Product search and quick order by SKU. In catalogs above 10,000 SKUs, they often account for more than half of the conversion gain.
