A well-built price grid is the difference between a store that controls margin and one that suffers it. On Shopify or PrestaShop, the grid can live in a shared Google Sheet, in native price lists, or in a dedicated tool. What matters is that it formally exists and is actively maintained.
The 4 axes of an e-commerce price grid
A good grid crosses four dimensions:
- Product — SKU or family (manufacturer reference, category, line).
- Customer segment — B2C, pro, reseller, enterprise, partners.
- Channel — direct site, marketplace (Amazon, Cdiscount), outbound feeds (Google Shopping, Meta).
- Context — full price, scheduled promo, sales period, private sales.
Concrete examples: 3 grid models that work
Single-product DNVB grid
Hybrid B2C + B2B grid
Advanced multi-segment grid
Building your price grid in 6 steps
- List real segments — not marketing segments, but the ones where you already apply a different price (retail consumer, pro with VAT ID, reseller with partner code).
- Pick currencies — based on real markets. EUR + USD covers 80% of French DNVBs.
- Define rounding rules — psychological (.90, .99), commercial (.50, .00), or exact (daily FX rate). Document the rule per currency.
- Choose the support — Sheets below 200 SKUs, Airtable or Seegea above. Shopify Plus price lists are useful but do not replace a single source.
- Sync with the CMS — push to Shopify or PrestaShop. Avoid CSV roundtrips that silently drift.
- Set up a monthly audit — grid ↔ CMS ↔ outbound feed gap check. 30 min/month saves weeks of cleanup later.
The 3 mistakes that make a grid unusable

Price grid and Shopify Plus price lists: how they fit together
Shopify Plus offers market-level price lists (B2B catalog, multi-currency). Powerful, but not a replacement for a source grid. The Shopify Plus price list is the execution channel — it needs an external source that computes and pushes the right prices. Seegea plays that source + control role.
Price grid and PrestaShop: customer groups and specific prices
PrestaShop natively handles customer groups (B2C, Pro, Reseller) with distinct prices, and specific prices with start/end dates. Backoffice editing is viable up to 200-300 SKUs. Beyond that, the UI slows down and mass edits become tedious — Seegea edits 500 prices in minutes on PrestaShop too.
Comparison: tools to maintain a price grid
| Criterion | Sheets + manual sync | Seegea |
|---|---|---|
| Setup time | 1 hour | 48 hours (guided onboarding) |
| Editing 500 prices | 20 to 30 min + manual push | 3 min + auto push |
| Multi-currency with rounding | Complex formulas | Configurable rules |
| Change history | 90 days (Google) | 365 days with diff |
| Rollback after mistake | Manual, listing by listing | Ctrl+Z, full bulk |
| Immediate push to CMS | CSV or ad hoc API | Native, immediate |
| Per-segment prices | Separate columns | Dedicated views per segment |

Price grid and SEO: the permanent-strikethrough trap
A healthy grid plans periods without promotion. Why? Because a permanent strikethrough (over 12 consecutive weeks) loses credibility, and because the Omnibus directive requires a reference price actually applied during the previous 30 days. If your grid always shows a discount, you no longer have a valid reference price — so no compliant strikethrough either.
Maintenance: the real topic
Building a grid is a project. Maintaining it is a ritual. The best teams we work with run a monthly audit (30 min) and a quarterly cleanup (2 hours). Without that rhythm, even the best grid degrades in 6 months.
Conclusion: the price grid is an asset, not a constraint
A clean, maintained grid becomes an operational asset that accelerates everything: new country launch, new line, flash promo, catalog refresh. Seegea was built in France, between Annecy and Chantilly, by e-commerce operators who know this work from the inside. If maintaining your grid is starting to weigh, a live demo will show you exactly what can be automated.
